I/O, I/O how well do you know good bad ugly server storage I/O iops?

How well do you know good bad ugly I/O iops?

server storage i/o iops activity data infrastructure trends

Updated 2/10/2018

There are many different types of server storage I/O iops associated with various environments, applications and workloads. Some I/Os activity are iops, others are transactions per second (TPS), files or messages per time (hour, minute, second), gets, puts or other operations. The best IO is one you do not have to do.

What about all the cloud, virtual, software defined and legacy based application that still need to do I/O?

If no IO operation is the best IO, then the second best IO is the one that can be done as close to the application and processor as possible with the best locality of reference.

Also keep in mind that aggregation (e.g. consolidation) can cause aggravation (server storage I/O performance bottlenecks).

Example of aggregation (consolidation) causing aggravation (server storage i/o blender bottlenecks)

And the third best?

It’s the one that can be done in less time or at least cost or effect to the requesting application, which means moving further down the memory and storage stack.

Leveraging flash SSD and cache technologies to find and fix server storage I/O bottlenecks

On the other hand, any IOP regardless of if for block, file or object storage that involves some context is better than those without, particular involving metrics that matter (here, here and here [webinar] )

Server Storage I/O optimization and effectiveness

The problem with IO’s is that they are a basic operations to get data into and out of a computer or processor, so there’s no way to avoid all of them, unless you have a very large budget. Even if you have a large budget that can afford an all flash SSD solution, you may still meet bottlenecks or other barriers.

IO’s require CPU or processor time and memory to set up and then process the results as well as IO and networking resources to move data too their destination or retrieve them from where they are stored. While IO’s cannot be eliminated, their impact can be greatly improved or optimized by, among other techniques, doing fewer of them via caching and by grouping reads or writes (pre-fetch, write-behind).

server storage I/O STI and SUT

Think of it this way: Instead of going on multiple errands, sometimes you can group multiple destinations together making for a shorter, more efficient trip. However, that optimization may also mean your drive will take longer. So, sometimes it makes sense to go on a couple of quick, short, low-latency trips instead of one larger one that takes half a day even as it accomplishes many tasks. Of course, how far you have to go on those trips (i.e., their locality) makes a difference about how many you can do in a given amount of time.

Locality of reference (or proximity)

What is locality of reference?

This refers to how close (i.e., its place) data exists to where it is needed (being referenced) for use. For example, the best locality of reference in a computer would be registers in the processor core, ready to be acted on immediately. This would be followed by levels 1, 2, and 3 (L1, L2, and L3) onboard caches, followed by main memory, or DRAM. After that comes solid-state memory typically NAND flash either on PCIe cards or accessible on a direct attached storage (DAS), SAN, or NAS device. 

server storage I/O locality of reference

Even though a PCIe NAND flash card is close to the processor, there still remains the overhead of traversing the PCIe bus and associated drivers. To help offset that impact, PCIe cards use DRAM as cache or buffers for data along with meta or control information to further optimize and improve locality of reference. In other words, this information is used to help with cache hits, cache use, and cache effectiveness vs. simply boosting cache use.

SSD to the rescue?

What can you do the cut the impact of IO’s?

There are many steps one can take, starting with establishing baseline performance and availability metrics.

The metrics that matter include IOP’s, latency, bandwidth, and availability. Then, leverage metrics to gain insight into your application’s performance.

Understand that IO’s are a fact of applications doing work (storing, retrieving, managing data) no matter whether systems are virtual, physical, or running up in the cloud. But it’s important to understand just what a bad IO is, along with its impact on performance. Try to identify those that are bad, and then find and fix the problem, either with software, application, or database changes. Perhaps you need to throw more software caching tools, hypervisors, or hardware at the problem. Hardware may include faster processors with more DRAM and faster internal busses.

Leveraging local PCIe flash SSD cards for caching or as targets is another option.

You may want to use storage systems or appliances that rely on intelligent caching and storage optimization capabilities to help with performance, availability, and capacity.

Where to gain insight into your server storage I/O environment

There are many tools that you can be used to gain insight into your server storage I/O environment across cloud, virtual, software defined and legacy as well as from different layers (e.g. applications, database, file systems, operating systems, hypervisors, server, storage, I/O networking). Many applications along with databases have either built-in or optional tools from their provider, third-party, or via other sources that can give information about work activity being done. Likewise there are tools to dig down deeper into the various data information infrastructure to see what is happening at the various layers as shown in the following figures.

windows and linux storage I/O performance
Insight and awareness via operating system tools on Windows and Linux

In the above example, Spotlight on Windows (SoW) which you can download for free from Dell here along with Ubuntu utilities are shown, You could also use other tools to look at server storage I/O performance including Windows Perfmon among others.

vmware server storage I/O performance
Using Visual ESXtop to dig deeper into virtual server storage I/O performance

vmware server storage i/o cache
Gaining insight into virtual server storage I/O cache performance

Wrap up and summary

There are many approaches to address (e.g. find and fix) vs. simply move or mask data center and server storage I/O bottlenecks. Having insight and awareness into how your environment along with applications is important to know to focus resources. Also keep in mind that a bit of flash SSD or DRAM cache in the applicable place can go along way while a lot of cache will also cost you cash. Even if you cant eliminate I/Os, look for ways to decrease their impact on your applications and systems.

Green and Virtual IT Data Center Primer

Green and Virtual Data Center Primer

Moving beyond Green Hype and Green washing

Green IT is about enabling efficient, effective and productive information services delivery. There is a growing green gap between green hype messaging or green washing and IT pain point issues including limits on availability or rising costs of power, cooling, floor-space as well as e-waste and environmental health and safety (PCFE). To close the gap will involve addressing green messaging and rhetoric closer to where IT organizations pain points are and where budget dollars exists that can address PCFE and other green related issues as a by-product. The green gap will also be narrowed as awareness of broader green related topics coincide with IT data center pain points, in other words, alignment of messaging with IT issues that have or will have budget dollars allocated towards them to sustain business and economic growth via IT resource usage efficiency. Read more here.

There are many aspects to "Green" Information Technology including servers, storage, networks and associated management tools and techniques. The reasons and focus of "Green IT" including "Green Data Storage ", "Green Computing" and related focus areas are varied to discuss diverse needs, issues and requirements including among others:

  • Power, Cooling, Floor-space, Environmental (PCFE) related issues or constraints
  • Reduction of carbon dioxide (CO2) emissions and other green house gases (GHGs)
  • Business growth and economic sustain in an environmental friendly manner
  • Proper disposal or recycling of environmental harmful retired technology components
  • Reduction or better efficiency of electrical power consumption used for IT equipment
  • Cost avoidance or savings from lower energy fees and cooling costs
  • Support data center and application consolidation to cut cost and management
  • Enable growth and enhancements to application service level objectives
  • Maximize the usage of available power and cooling resources available in your region
  • Compliance with local or federal government mandates and regulations
  • Economic sustain and ability to support business growth and service improvements
  • General environmental awareness and stewardship to save and protect the earth

While much of the IT industry focuses on CO2 emissions footprints, data management software and electrical power consumption, cooling and ventilation of IT data centers is an area of focus associated with "Green IT" as well as a means to discuss more effective use of electrical energy that can yield rapid results for many environments. Large tier-1 vendors including HP and IBM among others who have an IT and data center wide focus have services designed to do quick assessments as well as detailed analysis and re-organization of IT data center physical facilities to improve air flow and power consumption for more effective cooling of IT technologies including servers, storage, networks and other equipment.

Similar to your own residence, basic steps to improve your cooling effectiveness can lead to use of less energy to cut your budget impact, or, enable you to do more with what you already have with your cooling capacity to support growth, acquisitions and or consolidation initiatives. Vendors are also looking at means and alternatives for cooling IT equipment ranging from computer assisted computational fluid dynamics (CFD) software analysis of data center cooling and ventilation to refrigerated cooling racks some leveraging water or inert liquid cooling.

Various metrics exists and others are evolving for measuring, estimating, reporting, analyzing and discussing IT Data Center infrastructure resource topics including servers, storage, networks, facilities and associated software management tools from a power, cooling and green environmental standpoint. The importance of metrics is to focus on the larger impact of a piece of IT equipment that includes its cost and energy consumption that factors in cooling and other hosting or site environmental costs. Naturally energy costs and CO2 (carbon offsets) will vary by geography and region along with type of electrical power being used (Coal, Natural Gas, Nuclear, Wind, Thermo, Solar, etc) and other factors that should be kept in perspective as part of the big picture.

Consequently your view and needs or interests around "Green" IT may be from an electrical power conservation perspective to maximize your power consumption or to adapt to a given power footprint or ceiling. Your focus around "Green" Data Centers and Green Storage may be from a carbon savings standpoint or proper disposition of old and retired IT equipment or from a data center cooling standpoint. Another area of focus may be that you are looking to cut your data footprint to align with your power, cooling and green footprint while enhancing application and data service delivery to your customers.

Green and Virtual Metrics

Chapter 5 "Measurement, Metrics, and Management of IT Resources" in the book "The Green and Virtual Data Center" (CRC Press) takes a look at the importance of being able to measure and monitor to enable effective management and utilization of IT resources across servers, storage, I/O networks, software, hardware and facilities.

There are many different points of interest for collecting metrics in an IT data center for servers, storage, networking and facilities along with various points of interest or perspectives. Data center personal have varied interest from a facilities to a resource (server, storage, networking) usage and effectiveness perspective for normal use as well as planning purposes or comparison when evaluating new technology. Vendors have different uses for metrics during R&D, Q/A testing and marketing or sales campaigns as well as on-going service and support. Industry trade groups including 80 Plus, SNIA and the green grid along with government groups including the EPA Energy Star are working to define and establish applicable metrics pertinent for Green and Virtual data centers.

Activity / Watt Amount of work accomplished per unit of energy consumed. This could be IOPS, Transactions or Bandwidth per watt. Indicator how much work and how efficient energy is being used to accomplish useful work. This metric applies to active workloads or actively used and frequently accessed storage and data. Examples would be IOPS per watt, Bandwidth per watt, Transactions per watt, Users or streams per watt. Activity per watt should also be used in conjunction with another metric such as how much capacity is supported per watt and total watts consumed for a representative picture.

IOPS / Watt

Number of I/O operations (or transactions) / energy (watts)

Indicator of how effectively energy is being used to perform a given amount of work. The work could be I/Os, transactions, throughput or other indicator of application activity. For example SPC-1 / Watt, SPEC / Watt, TPC / Watt, transaction / watt,  IOP / Watt.

Bandwidth / Watt GBPS or TBPS or PBPS / Watt Amount of data transferred or moved per second and energy used. Often confused with Capacity per watt This indicates how much data is moved or accessed per second or time interval per unit of energy consumed. This is often confused with capacity per watt given that both bandwidth and capacity reference GByte, TByte, PByte.

Capacity / Watt

GB or TB or PB (storage capacity space / watt

Indicator of how much capacity (space) or bandwidth supported in a given configuration or footprint per watt of energy. For inactive data or off-line and archive data, capacity per watt can be an effective measurement gauge however for active workloads and applications activity per watt also needs to be looked at to get a representative indicator of how energy is being used

Mhz / Watt

Processor performance / energy (watts)

Indicator of how effectively energy is being used by a CPU or processor.

Carbon Credit

Various power, cooling, floor space and green storage or IT  related metrics

Metrics include Data center Efficiency (DCiE) via the greengrid which is the indicator ratio of a IT data center energy efficiency defined as IT equipment (servers, disk and tape storage, networking switches, routers, printers, etc) / Total facility power x 100 (for percentage). For example, if the sum of all IT equipment energy usage resulted in 1,500 kilowatt hours (kWh) per month yet the total facility power including UPS, energy switching, power conversation and filtering, cooling and associated infrastructure costs as well as IT equipment resulting in 3,500 kWh, the DCiE would be (1,500 / 3,500) x 100 = 43%. DCiE can be used as a ratio for example to show in the above scenario that IT equipment accounts for about 43% of energy consumed by the data center with in this scenario 57% of electrical energy being consumed by cooling, conversion and conditioning or lighting.

Power usage effectiveness (PUE) is the indicator ratio of total energy being consumed by the data center to energy being used to operate IT equipment. PUE is defined as total facility power / IT equipment energy consumption. Using the above scenario PUE = 2.333 (3,500 / 1,500) which means that a server requiring 100 watts of power would actually require (2.333 * 100) 233.3 watts of energy that includes both direct power and cooling costs. Similarly a storage system that required 1,500 kWh of energy to power would require (1,500*2.333) 3,499.5 kWh of electrical power including cooling.

Another metric that has the potential to have meaning is Data center Performance Efficiency (DCPE) that takes into consideration how much useful and effective work is performed by the IT equipment and data center per energy consumed. DCPE is defined as useful work / total facility power with an example being some number of transactions processed using servers, networks and storage divided by energy for the data center to power and cool the equipment. An relatively easy and straightforward implementation of DCPE is an IOPs per watt measurement that looks at how many IOPs can be performed (regardless of size or type such as reads or writes) per unit of energy in this case watts.

DCPE = Useful work / Total facility power, for example IOPS per watt of energy used

DCiE = IT equipment energy / Total facility power = 1 / PUE

PUE = Total facility energy / IT equipment energy

IOPS per Watt = Number of IOPs (or bandwidth) / energy used by the storage system

The importance of these numbers and metrics is to focus on the larger impact of a piece of IT equipment that includes its cost and energy consumption that factors in cooling and other hosting or site environmental costs. Naturally energy costs and CO2 (carbon offsets) will vary by geography and region along with type of electrical power being used (Coal, Natural Gas, Nuclear, Wind, Thermo, Solar, etc) and other factors that should be kept in perspective as part of the big picture. Learn more in Chapter 5 "Measurement, Metrics, and Management of IT Resources" in the book "The Green and Virtual Data Center" (CRC) and in the book Cloud and Virtual Data Storage Networking (CRC).

Cloud storage: Is It All About Cost?

Is cloud storage all about removing cost, cost cutting, free storage? Or perhaps even getting something else in addition to free storage?

You might ask: what type of cloud storage am I referring to? That’s a great question. After all, there are many types or categories of public cloud storage services, not to mention private and hybrid options. There are cloud storage services for consumers to save and share their photos, videos, music and other documents to. Then there is business and enterprise file, document, object and collaboration cloud storage options. Read the entire article here.

    Server storage I/O Intel NUC nick knack notes – First impressions

    Storage I/O trends

    Server storage I/O Intel NUC nick knack notes – First impressions

    This is the first of a two-part (part II here) series of my experiences (and impressions) using an Intel NUC ( a 4th generation model) for various things about cloud, virtual, physical and software defined server storage I/O networking.

    The NUC has been around new for a few years and continues to evolve and recently I bought my first one (e.g. a 4th generation model) to join some other servers that I have. My reason for getting a NUC is to use it as a simple low-power platform to run different software on including bare-metal OS, hypervisors, cloud, virtual and software defined server storage and networking applications on that might otherwise be on an old laptop or mini-tower.

    Introducing Intel Next Unit Computing aka NUC

    For those not familiar, NUC is a series of products from Intel called Next Unit Computing that offer an alternative to traditional mini-desktop or even laptop and notebooks. There are several different NUC models available including the newer 5th generation models (click here to see various models and generations). The NUCs are simple, small units of computing with an Intel processor and room for your choice of memory, persistent storage (e.g. Hard Disk Drive (HDD) or flash Solid State Device (SSD), networking, video, audio and other peripheral device attachment.

    software (not supplied) is defined by what you choose to use such as a Windows or *nix operating system, VMware ESXi, Microsoft Hyper-V, KVM or Xen hypervisor, or some other applications. The base NUC package includes front and rear-side ports for attaching various devices. In terms of functionality, think of a laptop without a keyboard or video screen, or in terms of a small head-less (e.g. no monitor) mini-tower desktop workstation PC.

    Which NUC to buy?

    If you need to be the first with anything new, then jump direct to the recently released 5th generation models.

    On the other hand, if you are looking for a bargain, there are some good deals on 4th generation or older. likewise depending on your processor speed and features needed along with available budget, those criteria and others will direct you to a specific NUC model.

    I went with a 4th generation NUC realizing that the newer models were just around the corner as I figured could always get another (e.g. create a NUC cluster) newer model when needed. In addition I also wanted a model that had enough performance to last a few years of use and the flexibility to be reconfigured as needed. My choice was a model D54250WYK priced around $352 USD via Amazon (prices may vary by different venues).

    Whats included with a NUC?

    My first NUC is a model D54250WYK (e.g. BOXD54250WYKH1 ) that you can view the specific speeds and feeds here at the Intel site along with ordering info here at Amazon (or your other preferred venue).

    View and compare other NUC models at the Intel NUC site here.

    The following images show the front-side two USB 3.0 ports along with head-phone (or speaker) and microphone jacks. Looking at the rear-side of the NUC there are a couple of air vents, power connector port (external power supply), mini-display and HDMI video port, GbE LAN, and two USB 3.0 ports.

    Warranty3-year limited

    Processor Speeds and Feeds

    There are various Intel Core i3 and i5 processors available depending on specific NUC model, such as my 54250WYK has a two core (1.3Ghz each) 4th generation i5-4250U (click here to see Intel speeds and feeds) which includes Intel Visual BIOS, Turbo Boost, Rapid Start and virtualization support among other features.

    Note that features vary by processor type, along with other software, firmware or BIOS updates. While the 1.3Ghz two core (e.g. max 2.6Ghz) is not as robust as faster quad (or more) cores running at 3.0Ghz (or faster), for most applications including as a first virtual lab or storage sand box among other uses, it will be fast enough or comparable to a lower-mid range laptop capabilities.

    What this all means

    In general I like the NUC so much that I bought one (model 54250) and would consider adding another in the future for somethings, however also see the need to continue using my other compute servers for different workloads.

    This wraps up part I of this two-part series and what this means is that I like the idea of a Intel NUC I bought one. Continue reading in part-two here where I cover the options that I added to my NUC, initial configuration, deployment, use and additional impressions.

    Ok, nuff said for now, check out part-two here.

    Server storage I/O Intel NUC nick knack notes – Second impressions

    Storage I/O trends

    Server storage I/O Intel NUC nick knack notes – Second impressions

    This is the second of a two-part series about my first and second impressions of the Intel NUC (Next Unit Computing). In the first post (here) I give an overview and my first impressions while in this post lets look at options added to my NUC model 54250, first deployment use and more impressions.

    Intel® NUC with Intel® Core™ i5 Processor and 2.5-Inch Drive Support (NUC5i5RYH) via Intel.com

    What you will want to add to a NUC

    Since the NUC is a basic brick with a processor mounted on its mother board, you will need to add memory, some type of persistent storage device (mSATA, SATA or USB based) and optionally a WiFi card.

    One of the nice things about the NUC is that in many ways it is the equivalent functionality of a laptop or mini-tower without the extra overhead (cost, components, packaging) enabling you to customize as needed for your specific requirements. For example there is no keyboard, mouse, video screen, WiFi, Hard Disk Drive (HDD) or flash Solid State Device (SSD) included with an operating system pre-installed. There is no least memory required enabling you to decide how much to configure while using compatible laptop style memory. Video and monitors attach via HDMI or mini-port including VGA devices via an adapter cable. Keyboard and mouse if needed are handled via USB ports.

    Here is what I added to my NUC model 5420.

    1Crucial 16GB Kit (2 x 8GB) DDR3 1600 (PC3-12800) SODIMM 204-Pin Notebook Memory
    1Intel Network 7260 WiFi Wireless-AC 7260 H/T Dual Band 2×2 AC+Bluetooth HMC. Here is link to Intel site for various drivers.
    1500GB Samsung Electronics 840 EVO mSATA 0.85-Inch Solid State Drive
    1SATA HDD, SSD or HHDD/SSHD (I used one of my existing drives)

    Note that you will also need to supply some type of Keyboard Video Mouse (KVM), in my case I used a HDMI to VGA adapter cable to attach the NUC via HDMI (for video) and USB (keyboard and mouse) to my Startech KVM switch.

    Following images show on the left Intel WiFi card installed and on the right, a Samsung 840 EVO mSATA 500GB flash SSD installed above the WiFi card. Also notice on the far right of the images the two DDR3 "notebook" class DRAM DIMM slots.

    NUC WiFi cardmSATA SSD
    Left: Intel WiFi card installed and Right Samsung EVO mSATA SSD card (sits above WiFi card)

    Note that the NUC (as do many laptops) accepts 9mm or smaller thin 7mm height HDDs and SSDs in its SATA drive bay. I mention this because some of the higher-capacity 2TB 2.5" SFF drives are taller than 9m as shown in the above image and do not fit in the NUC internal SATA drive bay. While many devices and systems support 2.5" drive slots for HDD, SSD or HHDD/SSHDs, pay attention to the height and avoid surprises when something does not fit like it was assumed to.

    2.5 HDD and SSDs
    Low-profile and tall-profile 2.5" SFF HDDs

    Additional drives and devices can be attached using external USB 3.0 ports including HDDs, SSDs or even USB to GbE adapters if needed. You will need to supply your own operating system, hypervisor, storage, networking or other software, such as Windows, *nix, VMware ESXi, Hyper-V, KVM, Xen, OpenStack or any of the various ZFS based (among others) storage appliances.

    Unpacking and physical NUC installation

    Initial setup and physical configuration of the NUC is pretty quick with the only tool needed being a Philips screw driver.

    NUC and components ready for installation
    Intel NUC 5420 and components ready for installation

    With all the components including the NUC itself laid out for a quick inventory including recording serial numbers (see image above), the next step is to open up the NUC by removing four Philip screws from the bottom. Once the screws are removed and bottom plate removed, the SATA drive bay opens up to reach the slots of memory, mSATA SSD and WiFi card (see images below). Once the memory, mSATA and WiFi cards are installed, the SATA drive bay coverage those components and it is time to install a 2.5" standard height HDD or SSD. For my first deployment I installed temporarily installed on of my older HHDDs a 750GB Seagate Momentus XT that will be replaced by something newer soon.

    After the components are installed, it is time to replace the bottom cover plate of the NUC securing in place with the four screws previously removed. Next up is attaching any external devices via USB and other ports including KVM and LAN network connection. Once the hardware is ready, its time to power up the NUC and checkout the Visual BIOS (or UEFI) as shown below.

    Intel NUC Visual BIOSIntel NUC Visual BIOS display
    NUC VisualBIOS screen shot examples

    At this point unless you have already installed an operating system, hypervisor or other software on a HDD, SSD or USB device, it is time to install your prefered software.

    Windows 7

    First up was Windows 7 as I already had an image built on the HHDD that required some drivers to be added. specifically, a visit to the Intel resources site (See NUC resources and links section later in this post) was made to get a LAN GbE, WiFi and USB drivers. Once those were installed the on-board GbE LAN port worked good as did the WiFi. Another driver that needed to be download was for a USB-GbE adapter to add another LAN connection. Also a couple of reboots were required for other Windows drivers and configuration changes to take place to correct some transient problems including KVM hangs which eventually cleared themselves up.

    Windows 2012 R2

    Following Windows 7, next up was a clean install of Windows 2012 R2 which also required some drivers and configuration changes. One of the challenges is that Windows 2012 R2 is not officially supported on the NUC with its GbE LAN and WiFi cards. However after doing some searches and reading a few posts including this and this, a solution was found and Windows 2012 R2 and its networking are working good.

    Ubuntu and Clonezilla

    Next up was a quick install of Ubuntu 14.04 which went pretty smooth, as well as using Clonezilla to do some drive maintenance, move images and partitions among other things.

    VMware ESXi 5.5U2

    My first attempt at installing a standard VMware ESXi 5.5U2 image ran into problems due to the GbE LAN port not being seen. The solution is to use a different build, or custom ISO that includes the applicable GbE LAN driver (e.g. net-e1000e-2.3.2.x86_64.vib) and some useful information at Florian Grehl site (@virten) and over at Andreas Peetz site (@VFrontDe) including SATA controller driver for xahci. Once the GbE driver was added (same driver that addresses other Intel NIC I217/I218 based systems) along with updating the SATA driver, VMware worked fine.

    Needless to say there are many other things I plan on doing with the NUC both as a standalone bare-metal system as well as a virtual platform as I get more time and projects allow.

    What about building your NUC alternative?

    In addition to the NUC models available via Intel and its partners and accessorizing as needed, there are also special customized and ruggedized NUC versions similar to what you would expect to find with laptop, notebooks, and other PC based systems.

    If you are looking to do more than what Intel and its partners offer, then there are some other options such as to increase the number of external ports among other capabilities. One option which I recently added to my collection of systems is an DIY (Do It Yourself) MSI ProBox (VESA mountable) such as this one here.

    With the MSI ProBox, they are essentially a motherboard with an empty single cpu socket (e.g. LGA 1150 up to 65W) for supporting various processors, two empty DDR3 DIMM slots, 2 empty 2.5" SATA ports among other capabilities. Enclosures such as the MSI ProBox give you flexibility creating something more robust beyond a basic NUC yet smaller than a traditional server depending on your specific needs.

    Looking for other small form factor modular and ruggedized server options as an alternative to a NUC, than check out those from Xi3, Advantech, Cadian Networks, and Logic Supply among many others.

    Storage I/O trends

    First NUC impressions

    Overall I like the NUC and see many uses for it from consumer, home including entertainment and media systems, video security surveillance as well as a small server or workstation device. In addition, I can see a NUC being used for smaller environments as desktop workstations or as a lower-power, lower performance system including as a small virtualization host for SOHO, small SMB and ROBO environments. Another usage is for home virtual lab as well as gaming among other scenarios including simple software defined storage proof of concepts. For example, how about creating a small cluster of NUCs to run VMware VSAN, or Datacore, EMC ScaleIO, Starwind, Microsoft SOFS or Hyper-V as well as any of the many ZFS based NAS storage software applications.

    Pro’s – Features and benefits

    Small, low-power, self-contained with flexibility to choose my memory, WiFi, storage (HDD or SSD) without the extra cost of those items or software being included.

    Con’s – Caveats or what to look out for

    Would be nice to have another GbE LAN port however I addressed that by adding a USB 3.0 to GbE cable, likewise would be nice if the 2.5" SATA drive bay supported tall height form-factor devices such as the 2TB devices. The work around for adding larger capacity and physically larger storage devices is to use the USB 3.0 ports. The biggest warning is if you are going to venture outside of the official supported operating system and application software realm be ready to load some drivers, possibly patch and hack some install scripts and then plug and pray it all works. So far I have not run into any major show stoppers that were not addressed with some time spent searching (google will be your friend), then loading the drivers or making configuration changes.

    Storage I/O trends

    What this all means

    Intel NUC provides a good option for many situations that might otherwise need a larger mini-tower desktop workstations or similar systems both for home, consumer and small office needs. NUC can also be used for specialized pre-configured application specific situations that need low-power, basic system functionality and expansion options in a small physical footprint. In addition NUC can also be a good option for adding to an existing physical and virtual LAB or as a basis for starting a new one.

    So far I have found many uses for NUC which free up other systems to do other tasks while enabling some older devices to finally be retired. On the other hand like most any technology, while the NUC is flexible, its low power and performance are not enough to support other applications. However the NUC gives me flexibility to leverage the applicable unit of compute (e.g. server, workstation, etc.) that is applicable to a given task or put another way, use the right technology tool for the task at hand.

    For now I only need a single NUC to be a companion to my other HP, Dell and Lenovo servers as well as MSI ProBox, however maybe there will be a small NUC cluster, grid or ring configured down the road.

    What say you, do you have a NUC if so, how is it being used and tips, tricks or hints to share with others?

    Ok, nuff said for now.

    Revisiting RAID data protection remains relevant resource links

    Revisiting RAID data protection remains relevant and resources

    Storage I/O trends

    Updated 2/10/2018

    RAID data protection remains relevant including erasure codes (EC), local reconstruction codes (LRC) among other technologies. If RAID were really not relevant anymore (e.g. actually dead), why do some people spend so much time trying to convince others that it is dead or to use a different RAID level or enhanced RAID or beyond raid with related advanced approaches?

    When you hear RAID, what comes to mind?

    A legacy monolithic storage system that supports narrow 4, 5 or 6 drive wide stripe sets or a modern system support dozens of drives in a RAID group with different options?

    RAID means many things, likewise there are different implementations (hardware, software, systems, adapters, operating systems) with various functionality, some better than others.

    For example, which of the items in the following figure come to mind, or perhaps are new to your RAID vocabulary?

    RAID questions

    There are Many Variations of RAID Storage some for the enterprise, some for SMB, SOHO or consumer. Some have better performance than others, some have poor performance for example causing extra writes that lead to the perception that all parity based RAID do extra writes (some actually do write gathering and optimization).

    Some hardware and software implementations using WBC (write back cache) mirrored or battery backed-BBU along with being able to group writes together in memory (cache) to do full stripe writes. The result can be fewer back-end writes compared to other systems. Hence, not all RAID implementations in either hardware or software are the same. Likewise, just because a RAID definition shows a particular theoretical implementation approach does not mean all vendors have implemented it in that way.

    RAID is not a replacement for backup rather part of an overall approach to providing data availability and accessibility.

    data protection and durability

    What’s the best RAID level? The one that meets YOUR needs

    There are different RAID levels and implementations (hardware, software, controller, storage system, operating system, adapter among others) for various environments (enterprise, SME, SMB, SOHO, consumer) supporting primary, secondary, tertiary (backup/data protection, archiving).

    RAID comparison
    General RAID comparisons

    Thus one size or approach does fit all solutions, likewise RAID rules of thumbs or guides need context. Context means that a RAID rule or guide for consumer or SOHO or SMB might be different for enterprise and vise versa, not to mention on the type of storage system, number of drives, drive type and capacity among other factors.

    RAID comparison
    General basic RAID comparisons

    Thus the best RAID level is the one that meets your specific needs in your environment. What is best for one environment and application may be different from what is applicable to your needs.

    Key points and RAID considerations include:

    · Not all RAID implementations are the same, some are very much alive and evolving while others are in need of a rest or rewrite. So it is not the technology or techniques that are often the problem, rather how it is implemented and then deployed.

    · It may not be RAID that is dead, rather the solution that uses it, hence if you think a particular storage system, appliance, product or software is old and dead along with its RAID implementation, then just say that product or vendors solution is dead.

    · RAID can be implemented in hardware controllers, adapters or storage systems and appliances as well as via software and those have different features, capabilities or constraints.

    · Long or slow drive rebuilds are a reality with larger disk drives and parity-based approaches; however, you have options on how to balance performance, availability, capacity, and economics.

    · RAID can be single, dual or multiple parity or mirroring-based.

    · Erasure and other coding schemes leverage parity schemes and guess what umbrella parity schemes fall under.

    · RAID may not be cool, sexy or a fun topic and technology to talk about, however many trendy tools, solutions and services actually use some form or variation of RAID as part of their basic building blocks. This is an example of using new and old things in new ways to help each other do more without increasing complexity.

    ·  Even if you are not a fan of RAID and think it is old and dead, at least take a few minutes to learn more about what it is that you do not like to update your dead FUD.

    Wait, Isn’t RAID dead?

    There is some dead marketing that paints a broad picture that RAID is dead to prop up something new, which in some cases may be a derivative variation of parity RAID.

    data dispersal
    Data dispersal and durability

    RAID rebuild improving
    RAID continues to evolve with rapid rebuilds for some systems

    Otoh, there are some specific products, technologies, implementations that may be end of life or actually dead. Likewise what might be dead, dying or simply not in vogue are specific RAID implementations or packaging. Certainly there is a lot of buzz around object storage, cloud storage, forward error correction (FEC) and erasure coding including messages of how they cut RAID. Catch is that some object storage solutions are overlayed on top of lower level file systems that do things such as RAID 6, granted they are out of sight, out of mind.

    RAID comparison
    General RAID parity and erasure code/FEC comparisons

    Then there are advanced parity protection schemes which include FEC and erasure codes that while they are not your traditional RAID levels, they have characteristic including chunking or sharding data, spreading it out over multiple devices with multiple parity (or derivatives of parity) protection.

    Bottom line is that for some environments, different RAID levels may be more applicable and alive than for others.

    • Maintain Situational Awareness
    • Design for Performance and Availability
    • Determine Networked Server and Storage Patterns
    • Make Use of Applicable Technologies and Techniques

    If RAID is alive, what to do with it?

    If you are new to RAID, learn more about the past, present and future keeping mind context. Keeping context in mind means that there are different RAID levels and implementations for various environments. Not all RAID 0, 1, 1/0, 10, 2, 3, 4, 5, 6 or other variations (past, present and emerging) are the same for consumer vs. SOHO vs. SMB vs. SME vs. Enterprise, nor are the usage cases. Some need performance for reads, others for writes, some for high-capacity with low performance using hardware or software. RAID Rules of thumb are ok and useful, however keep them in context to what you are doing as well as using.

    What to do next?

    Take some time to learn, ask questions including what to use when, where, why and how as well as if an approach or recommendation are applicable to your needs.

    What This All Means

    What is my favorite or preferred RAID level?

    That depends, for some things its RAID 1, for others RAID 10 yet for others RAID 4, 5, 6 or DP and yet other situations could be a fit for RAID 0 or erasure codes and FEC. Instead of being focused on just one or two RAID levels as the solution for different problems, I prefer to look at the environment (consumer, SOHO, small or large SMB, SME, enterprise), type of usage (primary or secondary or data protection), performance characteristics, reads, writes, type and number of drives among other factors. What might be a fit for one environment would not be a fit for others, thus my preferred RAID level along with where implemented is the one that meets the given situation. However also keep in mind is tying RAID into part of an overall data protection strategy, remember, RAID is not a replacement for backup.

    What this all means

    Like other technologies that have been declared dead for years or decades, aka the Zombie technologies (e.g. dead yet still alive) RAID continues to be used while the technologies evolves. There are specific products, implementations or even RAID levels that have faded away, or are declining in some environments, yet alive in others. RAID and its variations are still alive, however how it is used or deployed in conjunction with other technologies also is evolving.

    DIY converged server software defined storage on a budget using Lenovo TS140

    Attention DIY Converged Server Storage Bargain Shoppers

    Software defined storage on a budget with Lenovo TS140

    server storage I/O trends

    Recently I put together a two-part series of some server storage I/O items to get a geek for a gift (read part I here and part II here) that also contain items that can be used for accessorizing servers such as the Lenovo ThinkServer TS140.

    Image via Lenovo.com

    Likewise I have done reviews of the Lenovo ThinkServer TS140 in the past which included me liking them and buying some (read the reviews here and here), along with a review of the larger TD340 here.

    Why is this of interest

    Do you need or want to do a Do It Yourself (DIY) build of a small server compute cluster, or a software defined storage cluster (e.g. scale-out), or perhaps a converged storage for VMware VSAN, Microsoft SOFS or something else?

    Do you need a new server, second or third server, or expand a cluster, create a lab or similar and want the ability to tailor your system without shopping or a motherboard, enclosure, power supply and so forth?

    Are you a virtualization or software defined person looking to create a small VMware Virtual SAN (VSAN) needing three or more servers to build a proof of concept or personal lab system?

    Then the TS140 could be a fit for you.

    storage I/O Lenovo TS140

    Why the Lenovo TS140 now?

    Recently I have seen a lot of site traffic on my site with people viewing my reviews of the Lenovo TS140 of which I have a few. In addition have got questions from people via comments section as well as elsewhere about the TS140 and while shopping at Amazon.com for some other things, noticed that there were some good value deals on different TS140 models.

    I tend to buy the TS140 models that are bare bones having power supply, enclosure, CD/DVD, USB ports, power supply and fan, processor and minimal amount of DRAM memory. For processors mine have the Intel E3-1225 v3 which are quad-core and that have various virtualization assist features (e.g. good for VMware and other hypervisors).

    What I saw on Amazon the other day (also elsewhere) were some Intel i3-4130 dual core based systems (these do not have all the virtualization features, just the basics) in a bare configuration (e.g. no Hard Disk Drive (HDD), 4GB DRAM, processor, mother board, power supply and fan, LAN port and USB with a price of around $220 USD (your price may vary depending on timing, venue, prime or other membership and other factors). Not bad for a system that you can tailor to your needs. However what also caught my eye were the TS140 models that have the Intel E3-1225 v3 (e.g. quad core, 3.2Ghz) processor matching the others I have with a price of around $330 USD including shipping (your price will vary depending on venue and other factors).

    What are some things to be aware of?

    Some caveats of this solution approach include:

    • There are probably other similar types of servers, either by price, performance, or similar
    • Compare apples to apples, e.g. same or better processor, memory, OS, PCIe speed and type of slots, LAN ports
    • Not as robust of a solution as those you can find costing tens of thousands of dollars (or more)
    • A DIY system which means you select the other hardware pieces and handle the service and support of them
    • Hardware platform approach where you choose and supply your software of choice
    • For entry-level environments who have floor-space or rack-space to accommodate towers vs. rack-space or other alternatives
    • Software agnostic Based on basically an empty server chassis (with power supplies, motherboard, power supplies, PCIe slots and other things)
    • Possible candidate for smaller SMB (Small Medium Business), ROBO (Remote Office Branch Office), SOHO (Small Office Home Office) or labs that are looking for DIY
    • A starting place and stimulus for thinking about doing different things

    What could you do with this building block (e.g. server)

    Create a single or multi-server based system for

    • Virtual Server Infrastructure (VSI) including KVM, Microsoft Hyper-V, VMware ESXi, Xen among others
    • Object storage
    • Software Defined Storage including Datacore, Microsoft SOFS, Openstack, Starwind, VMware VSAN, various XFS and ZFS among others
    • Private or hybrid cloud including using Openstack among other software tools
    • Create a hadoop big data analytics cluster or grid
    • Establish a video or media server, use for gaming or a backup (data protection) server
    • Update or expand your lab and test environment
    • General purpose SMB, ROBO or SOHO single or clustered server

    VMware VSAN server storageIO example

    What you need to know

    Like some other servers in this class, you need to pay attention to what it is that you are ordering, check out the various reviews, comments and questions as well as verify the make, model along with configuration. For example what is included and what is not included, warranty, return policy among other things. In the case of some of the TS140 models, they do not have a HDD, OS, keyboard, monitor, mouse along with different types of processors and memory. Not all the processors are the same, pay attention, visit the Intel Ark site to look up a specific processor configuration to see if it fits your needs as well as visit the hardware compatibility list (HCL) for the software that you are planning to use. Note that these should be best practices regardless of make, model, type or vendor for server, storage, I/O networking hardware and software.

    What you will need

    This list assumes that you have obtained a model without a HDD, keyboard, video, mouse or operating system (OS) installed

    • Update your BIOS if applicable, check the Lenovo site
    • Enable virtualization and other advanced features via your BIOS
    • Software such as an Operating System (OS), hypervisor or other distribution (load via USB or CD/DVD if present)
    • SSD, SSHD/HHDD, HDD or USB flash drive for installing OS or other software
    • Keyboard, video, mouse (or a KVM switch)

    What you might want to add (have it your way)

    • Keyboard, video mouse or a KVM switch (See gifts for a geek here)
    • Additional memory
    • Graphics card, GPU or PCIe riser
    • Additional SSD, SSHD/HHDD or HDD for storage
    • Extra storage I/O and networking ports

    Extra networking ports

    You can easily add some GbE (or faster ports) including use the PCIe x1 slot, or use one of the other slots for a quad port GbE (or faster), not to mention get some InfiniBand single or dual port cards such as the Mellanox Connectx II or Connect III that support QDR and can run in IBA or 10GbE modes. If you only have two or three servers in a cluster, grid, ring configuration you can run point to point topologies using InfiniBand (and some other network interfaces) without using a switch, however you decide if you need or want switched or non-switched (I have a switch). Note that with VMware (and perhaps other hypervisors or OS) you may need to update the drives for the Realtek GbE LAN on Motherboard port (see links below).

    Extra storage ports

    For extra storage space capacity (and performance) you can easily add PCIe G2 or G3 HBAs (SAS, SATA, FC, FCoE, CNA, UTA, IBA for SRP, etc) or RAID cards among others. Depending on your choice of cards, you can then attach to more internal storage, external storage or some combination with different adapters, cables, interposers and connectivity options. For example I have used TS140s with PCIe Gen 3 12Gbs SAS HBAs attached to 12Gbs SAS SSDs (and HDDs) with the ability to drive performance to see what those devices are capable of doing.

    TS140 Hardware Defined My Way

    As an example of how a TS140 can be configured, using one of the base E3-1224 v3 models with 4GB RAM, no HDD (e.g around $330 USD, your price will vary), add a 4TB Seagate HDD (or two or three) for around $140 USD each (your price will vary), add a 480GB SATA SSD for around $340 USD (your price will vary) with those attached to the internal SATA ports. To bump up network performance, how about a Mellanox Connectx II dual port QDR IBA/10GbE card for around $140 USD (your price will vary), plus around $65 USD for QSFP cable (you your price will vary), and some extra memory (use what you have or shop around) and you have a platform ready to go for around or under $1,000 USD. Add some more internal or external disks, bump up the memory, put in some extra network adapters and your price will go up a bit, however think about what you can have for a robust not so little system. For you VMware vgeeks, think about the proof of concept VSAN that you can put together, granted you will have to do some DIY items.

    Some TS140 resources

    Lenovo TS140 resources include

    • TS140 StorageIOlab review (here and here)
    • TS140 Lenovo ordering website
    • TS140 Data and Spec Sheet (PDF here)
    • Lenovo ThinkServer TS140 Manual (PDF here) and (PDF here)
    • Intel E3-1200 v3 processors capabilities (Web page here)
    • Enabling Virtualization Technology (VT) in TS140 BIOS (Press F1) (Read here)
    • Enabling Intel NIC (82579LM) GbE with VMware (Link to user forum and a blog site here)

    Image via Lenovo.com

    What this all means

    Like many servers in its category (price, capabilities, abilities, packaging) you can do a lot of different things with them, as well as hardware define with accessories, or use your own software. Depending on how you end how hardware defining the TS140 with extra memory, HDDs, SSDs, adapters or other accessories and software your cost will vary. However you can also put together a pretty robust system without breaking your budget while meeting different needs.

    Is this for everybody? Nope

    Is this for more than a lab, experimental, hobbyist, gamer? Sure, with some caveats Is this apples to apples comparison vs. some other solutions including VSANs? Nope, not even close, maybe apples to oranges.

    Do I like the TS140? Yup, starting with a review I did about a year ago, I liked it so much I bought one, then another, then some more.

    Are these the only servers I have, use or like? Nope, I also have systems from HP and Dell as well as test drive and review others

    Why do I like the TS140? It’s a value for some things which means that while affordable (not to be confused with cheap) it has features, salability and ability to be both hardware defined for what I want or need to use them as, along with software define them to be different things. Key for me is the PCIe Gen 3 support with multiple slots (and types of slots), reasonable amount of memory, internal housing for 3.5" and 2.5" drives that can attach to on-board SATA ports, media device (CD/DVD) if needed, or remove to use for more HDDs and SSDs. In other words, it’s a platform that instead of shopping for the motherboard, an enclosure, power supply, processor and related things I get the basics, then configure, and reconfigure as needed.

    Another reason I like the TS140 is that I get to have the server basically my way, in that I do not have to order it with a smallest number of HDDs, or that it comes with an OS, more memory than needed or other things that I may or may not be able to use. Granted I need to supply the extra memory, HDDs, SSDs, PCIe adapters and network ports along with software, however for me that’s not too much of an issue.

    What don’t I like about the TS140? You can read more about my thoughts on the TS140 in my review here, or its bigger sibling the TD340 here, however I would like to see more memory slots for scaling up. Granted for what these cost, it’s just as easy to scale-out and after all, that’s what a lot of software defined storage prefers these days (e.g. scale-out).

    The TS140 is a good platform for many things, granted not for everything, that’s why like storage, networking and other technologies there are different server options for various needs. Exercise caution when doing apples to oranges comparison on price alone, compare what you are getting in terms of processor type (and its functionality), expandable memory, PCIe speed, type and number of slots, LAN connectivity and other features to meet your needs or requirements. Also keep in mind that some systems might be more expensive that include a keyboard, HDD with an OS installed that if you can use those components, then they have value and should be factored into your cost, benefit, return on investment.

    And yes, I just added a few more TS140s that join other recent additions to the server storageIO lab resources…

    Anybody want to guess what I will be playing with among other things during the up coming holiday season?

    Ok, nuff said, for now…

    Server Storage I/O Cables Connectors Chargers & other Geek Gifts

    Server Storage I/O Cables Connectors Chargers & other Geek Gifts

    server storage I/O trends

    This is part one of a two part series for what to get a geek for a gift, read part two here.

    It is that time of the year when annual predictions are made for the upcoming year, including those that will be repeated next year or that were also made last year.

    It’s also the time of the year to get various projects wrapped up, line up new activities, get the book-keeping things ready for year-end processing and taxes, as well as other things.

    It’s also that time of the year to do some budget and project planning including upgrades, replacements, enhancements while balancing an over-subscribed holiday party schedule some of you may have.

    Lets not forget getting ready for vacations, perhaps time off from work with some time upgrading your home lab or other projects.

    Then there are the gift lists or trying to figure out what to get that difficult to shop for person particular geek’s who may have everything, or want the latest and greatest that others have, or something their peers don’t have yet.

    Sure I have a DJI Phantom II on my wish list, however also have other things on my needs list (e.g. what I really need and want vs. what would be fun to wish for).

    So here are some things for the geek or may have everything or is up on having the latest and greatest, yet forgot or didn’t know about some of these things.

    Not to mention some of these might seem really simple and low-cost, think of them like a Lego block or erector set part where your imagination will be your boundary how to use them. Also, most if not all of these are budget friendly particular if you shop around.

    Replace a CD/DVD with 4 x 2.5″ HDD’s or SSD’s

    So you need to add some 2.5" SAS or SATA HDD’s, SSD’s, HHDD’s/SSHD’s to your server for supporting your VMware ESXi, Microsoft Hyper-V, KVM, Xen, OpenStack, Hadoop or legacy *nix or Windows environment or perhaps gaming system. Challenge is that you are out of disk drive bay slots and you want things neatly organized vs. a rat’s nest of cables hanging out of your system. No worries assuming your server has an empty media bay (e.g. those 5.25" slots where CDs/DVDs or really old HDD’s go), or if you can give up the CD/DVD, then use that bay and its power connector to add ones of these. This is a 4 x 2.5" SAS and SATA drive bay that has a common power connector (molex male) with each drive bay having its own SATA drive connection. By each drive having its own SATA connection you can map the drives to an on-board available SATA port attached to a SAS or SATA controller, or attach an available port on a RAID adapter to the ports using a cable such as small form factor (SFF) 8087 to SATA.

    sas storage enclosuresas sata storage enclosure
    (Left) Rear view with Molex power and SATA cables (Right) front view

    I have a few of these in different systems and what I like about them is that they support different drive speeds, plus they will accept a SAS drive where many enclosures in this category only support SATA. Once you mount your 2.5" HDD or SSD using screws, you can hot swap (requires controller and OS support) the drives and move them between other similar enclosures as needed. The other thing I like is that there are front indicator lights as well as by each drive having its own separate connection, you can attach some of the drives to a RAID adapter while others connected to on-board SATA ports. Oh, and you can also have different speeds of drives as well.

    Power connections

    Depending on the type of your server, you may have Molex, SATA or some other type of power connections. You can use different power connection cables to go from one type (Molex) to another, create a connection for two devices, create an extension to reach hard to get to mounting locations.

    Warning and disclosure note, keep in mind how much power you are drawing when attaching devices to not cause an electrical or fire hazard, follow manufactures instructions and specification doing so at your own risk! After all, Just like Clark Grizzwald in National Lampoon Christmas Vacation who found you could attach extension cord to splitters to splitters and fan-out to have many lights attached, you don’t want to cause a fire or blackout when you plug to many drives in.


    National Lampoon Christmas Vacation

    Measuring Power

    Ok so you do not want to do a Clark Grizzwald (see above video) and overload a power circuit, or perhaps you simply want to know how many watts, amps or quality of your voltage is.

    There are many types of power meters along with various prices, some even have interfaces where you can grab event data to correlate with server storage I/O networking performance to do things such as IOP’s per watt among other metrics. Speaking of IOP’s per watt, check out the SNIA Emerald site where they have some good tools including a benchmark script that uses Vdbench to drive hot band workload (e.g. basically kick the crap out of a storage system).

    Back to power meters, I like the Kill A Watt series of meters as they give good info about amps, volts, power quality. I have these plugged into outlets so I can see how much power is being used by the battery backup units (BBU) aka UPS that also serve as power surge filters. If needed I can move these further downstream to watch the power intake of a specific server, storage, network or other device.

    Kill A Watt Power meter

    Standby and backup power

    Electrical power surge strips should be a given or considered common sense, however what is or should be common sense should be repeated so that it remains common sense, you should be using power surge strips or other devices.

    Standby, UPS and BBU

    For most situations a good surge suppressor will cover short power transients.

    APC power strips and battery backup
    Image via APC and model similar to those that I have

    For slightly longer power outages of a few seconds to minutes, that’s where battery backup up (BBU) units that also have surge suppression comes into play. There are many types, sizes with various features to meet your needs and budget. I have several of theses in a couple of different sizes not only for servers, storage and networking equipment (including some WiFi access points, routers, etc), I also have them for home things such as satellite DVR’s. However not everything needs to stay on while others simply need to stay on long-enough in order to shutdown manually or via automated power off sequences.

    Alternate Power Generation

    Generators are not just for the rich and famous or large data center, like other technologies they are available in different sizes, power capacity, fuel sources, manual or automated among other things.

    kohler residential generator
    Image via Kohler Power similar to model that I have

    Note that even with a typical generator there will be a time gap from the time power goes off until the generator starts, stabilizes and you have good power. That’s where the BBU and UPS mentioned above comes into play to bridge those time gaps which in my cases is about 25-30 seconds. Btw, knowing how much power your technology is drawing using tools such as the Kill A Watt is part of the planning process to avoid surprises.

    What about Solar Power

    Yup, whether it is to fit in and be green, or simply to get some electrical power when or where it is not needed to charge a battery or power some device, these small solar power devices are very handy.

    solar charger

    For example you can get or easily make an adapter to charge laptops, cell phones or even power them for normal use (check manufactures information on power usage, Amps and Voltage draws among other warnings to prevent fire and other things). Btw, not only are these handy for computer related things, they also work great for keeping batteries on my fishing boat charged so that I have my fish finder and other electronics, just saying.

    Fire suppression

    How about a new or updated smoke and fire detection alarm monitor, as well as fire extinguisher for the geek’s software defined hardware that runs on power (electrical or battery)?

    The following is from the site Fire Extinguisher 101 where you can learn more about different types of suppression technologies.

    Image via Fire Extinguisher 101
    • Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire it can extinguish. Geometric symbol (green triangle)
    • Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish. Geometric symbol (red square)
    • Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires – the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive. Geometric symbol (blue circle)
    • Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium, titanium, potassium and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating – they are designed for class D fires only. Geometric symbol (Yellow Decagon)
    • Class K fire extinguishers are for fires that involve cooking oils, trans-fats, or fats in cooking appliances and are typically found in restaurant and cafeteria kitchens. Geometric symbol (black hexagon)

    Wrap up for part I

    This wraps up part I of what to get a geek V2014, continue reading part II here.

    Part II 2014 Server Storage I/O Geek Gift ideas

    Part II 2014 Server Storage I/O Geek Gift ideas

    server storage I/O trends

    This is part two of a two part series for what to get a geek for a gift, read part one here.

    KVM switch

    Not to be confused with a software defined network (SDN) switch for the KVM virtualization hypervisor, how about the other KVM switch?

    kvm switch
    My KVM switch in use, looks like five servers are powered on.

    If you have several servers or devices that need a Keyboard Video Mouse connection, or are using A/B box or other devices, why not combine using a KVM switch. I bought the Startech shown above from Amazon which works out to be under $40 a port (connection) meaning I do not have to have Keyboards, Video monitors or Mouse for each of those systems.

    With my KVM shown above, I have used the easy setup to name each of the ports via the management software so that when a button is pressed, not only does the applicable screen appear, also a graphic text message overlay tell me which server is being displayed. This is handy for example as I have some servers that are identical (e.g. Lenovo TS140s) running VMware that a quick glance can help me verify I’m on the right one (e.g. without looking at the VMware host name or IP). This feature is also handy during power on self test (POST) when the servers physical or logical (e.g. VMware, Windows, Hyper-V, Ubuntu, Openstack, etc..) identity is known. Another thing I like about these is that on the KVM switch there is a single VGA type connector, while on the server end there is a VGA connector for attaching to the monitor port of the device, and a break out cable with USB for attaching to server to get Keyboard and Mouse.

    Single drive shoe box

    Usually things are in larger server or storage systems enclosures, however now and then there is the need to supply power to a HDD or SSD along with a USB or eSATA interface for attaching to a system. These are handy and versatile little aluminum enclosures.

    single drive sata enclosuredisk enclosure

    Note that you can now also find these types of cables that can do same or similar function for in side a server connection (check out this cable among others at Amazon)

    USB-SATA cable

    It would be easy to assume that everybody would have these by now particular since everybody (depending on who you listen to or what you read) has probably converted from a HDD to SSD. However for those who have not done an HDD to SSD, or simply a HDD to newer HDD conversion, or that have an older HDD (or SSD) lying around, these cables come in very handy. attach one end (e.g. the SATA end) to a HDD or SSD and the other to a USB port on a laptop, tablet or server. Caveat however with these is that they generally only have power (via USB) for a 2.5″ type drive so for a larger more power-hungry 3.5″ device, you would need a different powered cable, or small shoe box type enclosure.

    eSATA cable
    (Left) USB to SATA and (Right) eSATA to SATA cables

    Mophie USB charger

    There are many different types of mobile device chargers available along with multi-purpose cables. I like the Mophie which I received at an event from NetApp (Thanks NetApp) and the flexible connector I received from Dyn while at AWS re:Invent 2014 (Thanks Dyn, I’m also a Dyn customer fwiw).
    power chargerpower cable
    (Left) Mophie Power station and (Right) multi-connector cable

    The Mohpie has USB connector so that you can charge it via a charging station or via a computer, as well as attach a USB to Apple or other device connector. There is also a small connector for attach to other devices. This is where the dandy Dyn device comes into play as it has a USB as well as Apple and many other common connectors as shown in the figure below. Google around and I’m sure you can find both for sale, or as giveaways or something similar.

    SAS SATA Interposer

    sas interposerserver storage power
    (Left) SAS to SATA interposer (Right) Molex power with SATA connector to SAS

    Note that the above are intended for passing a SAS signal from a device such as HDD or SSD to a SAS based controller that happens to have SATA mechanical or keyed interfaces such as with some servers. This means that the real controller needs to be SAS and the attached drives can be SATA or SAS keeping in mind that a SATA device can plug into a SAS controller however not vise versa. You can find the above at Amazon among other venues. Need a dual-lane SAS connector as an alternative to the one shown above on the right, then check this one out at Amazon.

    Need to learn more about the many different facets of SAS and related technologies including how it coexists with iSCSI, Fibre Channel (FC), FCoE, InfiniBand and other interfaces, how about getting a free copy of SAS SANs for Dummies?

    SAS SANS for dummies

    There are also these for doing board level connections

    esata connectorsata to esata cablesata male to male gender changer
    Some additional SAS and SATA drive connectors

    In the above on the left are a female to female SATA cable with a male to male SATA gender changer attached to be used for example between a storage device and the SATA connector port on a servers motherboard, HBA or RAID controller. In the middle are shown some SATA female to female cables, as well as a SATA to eSATA (external SATA) cable (middle), and on the right are some SATA Male to SATA Male gender changes also shown being used on the left in the above figures.

    Internal Power cable / connectors

    If you or your geek are doing things in the lab or other environment adding and reconfiguring devices such as some of those mentioned above (or below), sooner or later there will be the need to do something with power cables and connectors.

    power meter
    Various cables, adapters and extender

    In the above figure are shown (top to bottom) a SATA male to molex, SATA female to SATA male and to its right SATA female to Molex. Below that are two SATA females to Molex, below that is a SATA male to dual Molex and on the bottom is a single SATA to dual SATA. Needless to say there are many other combinations of connectors as well as different genders (e.g. Male or Female) along with extenders. As mentioned above, pay attention to manufacturers recommend power draw and safety notices to prevent accidental electric shock or fire.

    Intel Edison kit for IoT and IoD

    Are you or your geek into the Internet of Things (IoT) or Internet of Devices (IoD) or other similar things and gadgets? Have you heard about Intel’s Edison breakout board for doing software development and attachment of various hardware things? Looking for something to move beyond a Raspberry Pi system?

    Over the hills, through the woods WiFi

    This past year I found Nanostation extended WiFi devices that solved a challenge (problem) which was how to get a secure WiFi signal up to a couple hundred yards through a thick forest between some hill’s.


    Image via UBNT.com, check out their other models as well as resources for different deployments

    The problem was it was to far and too many tree’s with leaves use a regular WiFi connection and too far to run cable if I did not need to. I found the solution by getting a pair of the Nanostation M2 putting them into bridge mode, then doing some alignment with their narrow beam antennas to bounce a signal through the woods. For those who simply need to go a long distance, these devices can be reconfigured to go several km’s line of sight. Click on the image above to see other models of the Nanostation as well as links to various resources on how they can be used for other things or deployments.

    How about some software

    • UpDraft Backup – This is a WordPress blog plugin that I use to back up my entire web including the templates, plug-ins, MySQL database and all other related components. While my dedicated private server gets backed up by my service provider (Bluehost), I wanted an extra detail of protection along with a copy placed at a different place (e.g. at my AWS account). Updraft is an example of an emerging class of tools for backing up and protecting cloud based and cloud born data. For example EMC recently acquired cloud backup startup Spanning who has the ability of protecting Salesforce, Google and other cloud based data.
    • Visual ESXtop – This is a great free tool that provides a nice interface and remote access for doing ESXtop functions normally accomplished from the ESXi console.
    • Microsoft Diskspd – If you or your geek is into server storage I/O performance and benchmark that has a Windows environment and looking for something besides Iometer, have them download the Microsoft Diskspd free utility.
    • Futuremark PCmark – Speaking of server storage I/O performance, check out Futuremark PCmark which will give your computer a great workout from graphics and video to compute, storage I/O and other common tasks.
    • RV Tools – Need to know more about your VMware virtual environment, take a quick inventory or something else, then your geek should have a copy of RV Tools from Robware.
    • iVMControl – For that vgeek how wants to be able to do simple VMware tasks from an iPhone, check out iVMControl tools. Its great, I don’t use it a lot, however there are times where I don’t need to or want to use a tablet or PC to reach my VMware environment, that’s when this virtual gadget comes into play.

    Livescribe Digital Pen and Paper

    How about a Livescribe digital pen and paper? Sure you can use a PC, Apple or other tablet, however some things are still easier done on a traditional paper and virtual pen. I got one of these about a year ago and use it for note taking, mocking up slides for presentations and in some cases have used this for creating figures and other things. It would be easy to see and place the Livescribe and a Windows or other tablet as an either or competitive however for me, I still see where they are better together addressing different things, at least for now.

    livescribe digital penlivescribe digital pen

    Tip: I you noticed in the above left image (e.g. the original) the lines in the top figure, compared to the lines in the figure on the right are different. If you encounter your livescribe causing lines to run on or into each other it is because your digital pen tip is sticking. It’s easy to check by looking at the tip of your digital pen and see if the small red light is on or off, or if it stays on when you press the pen tip. If it stays on, reset the pen tip. Also when you write, make sure to lift up on the pen tip so that it releases, otherwise you will get results like those shown on the right.

    Also check out this optional application that turns a Livescribe Echo pen like mine into a digital tablet allowing you to draw on-screen with certain applications and webinar tools.

    Some books for the geek

    Speaking of reading, for those who are not up on the No SQL and alternative SQL based databases including Mongo, Hbase, Riak, Cassandra, MySQL, add Seven Databases in Seven Weeks to your liust. Click on the image to read my book review of it as well as links to order it from Amazon. Seven Databases in Seven Weeks (A Guide to Modern Databases and the NoSQL Movement) is a book written Eric Redmond (@coderoshi) and Jim Wilson (@hexlib), part of The Pragmatic Programmers (@pragprog) series that takes a look at several non SQL based database systems.

    Where to get the above items

    • Ebay for new and used
    • Amazon for new and used
    • Newegg
    • PC Pit stop
    • And many other venues

    What this all means

    Note: Some of the above can be found at your favorite trade show or conference so keep that in mind for future gift giving.

    What interesting geek gift ideas or wish list items do you have?

    Of course if you have anything interesting to mention feel free to add it to the comments (keep it clean though ;) or feel free to send to me for future mention.

    In the meantime have a safe and happy holiday season for what ever holiday you enjoy celebrating anytime of the year.

    Data Storage Tape Update V2014, Its Still Alive

    Data Storage Tape Update V2014, It’s Still Alive

    server storage I/O trends

    A year or so ago I did a piece tape summit resources. Despite being declared dead for decades, and will probably stay being declared dead for years to come, magnetic tape is in fact still alive being used by some organizations, granted its role is changing while the technology still evolves.

    Here is the memo I received today from the PR folks of the Tape Storage Council (e.g. tape vendors marketing consortium) and for simplicity (mine), I’m posting it here for you to read in its entirety vs. possibly in pieces elsewhere. Note that this is basically a tape status and collection of marketing and press release talking points, however you can get an idea of the current messaging, who is using tape and technology updates.

    Tape Data Storage in 2014 and looking towards 2015

    True to the nature of magnetic tape as a data storage medium, this is not a low latency small post, rather a large high-capacity bulk post or perhaps all you need to know about tape for now, or until next year. Otoh, if you are a tape fan, you can certainly take the memo from the tape folks, as well as visit their site for more info.

    From the tape storage council industry trade group:

    Today the Tape Storage Council issued its annual memo to highlight the current trends, usages and technology innovations occurring within the tape storage industry. The Tape Storage Council includes representatives of BDT, Crossroads Systems, FUJIFILM, HP, IBM, Imation, Iron Mountain, Oracle, Overland Storage, Qualstar, Quantum, REB Storage Systems, Recall, Spectra Logic, Tandberg Data and XpresspaX.  

    Data Growth and Technology Innovations Fuel Tape’s Future
    Tape Addresses New Markets as Capacity, Performance, and Functionality Reach New Levels

    Abstract
    For the past decade, the tape industry has been re-architecting itself and the renaissance is well underway. Several new and important technologies for both LTO (Linear Tape Open) and enterprise tape products have yielded unprecedented cartridge capacity increases, much longer media life, improved bit error rates, and vastly superior economics compared to any previous tape or disk technology. This progress has enabled tape to effectively address many new data intensive market opportunities in addition to its traditional role as a backup device such as archive, Big Data, compliance, entertainment and surveillance. Clearly disk technology has been advancing, but the progress in tape has been even greater over the past 10 years. Today’s modern tape technology is nothing like the tape of the past.

    The Growth in Tape  
    Demand for tape is being fueled by unrelenting data growth, significant technological advancements, tape’s highly favorable economics, the growing requirements to maintain access to data “forever” emanating from regulatory, compliance or governance requirements, and the big data demand for large amounts of data to be analyzed and monetized in the future. The Digital Universe study suggests that the world’s information is doubling every two years and much of this data is most cost-effectively stored on tape.

    Enterprise tape has reached an unprecedented 10 TB native capacity with data rates reaching 360 MB/sec. Enterprise tape libraries can scale beyond one exabyte. Enterprise tape manufacturers IBM and Oracle StorageTek have signaled future cartridge capacities far beyond 10 TBs with no limitations in sight.  Open systems users can now store more than 300 Blu-ray quality movies with the LTO-6 2.5 TB cartridge. In the future, an LTO-10 cartridge will hold over 14,400 Blu-ray movies. Nearly 250 million LTO tape cartridges have been shipped since the format’s inception. This equals over 100,000 PB of data protected and retained using LTO Technology. The innovative active archive solution combining tape with low-cost NAS storage and LTFS is gaining momentum for open systems users.

    Recent Announcements and Milestones
    Tape storage is addressing many new applications in today’s modern data centers while offering welcome relief from constant IT budget pressures. Tape is also extending its reach to the cloud as a cost-effective deep archive service. In addition, numerous analyst studies confirm the TCO for tape is much lower than disk when it comes to backup and data archiving applications. See TCO Studies section below.

    • On Sept. 16, 2013 Oracle Corp announced the StorageTek T10000D enterprise tape drive. Features of the T10000D include an 8.5 TB native capacity and data rate of 252 MB/s native. The T10000D is backward read compatible with all three previous generations of T10000 tape drives.
    • On Jan. 16, 2014 Fujifilm Recording Media USA, Inc. reported it has manufactured over 100 million LTO Ultrium data cartridges since its release of the first generation of LTO in 2000. This equates to over 53 thousand petabytes (53 exabytes) of storage and more than 41 million miles of tape, enough to wrap around the globe 1,653 times.
    • April 30, 2014, Sony Corporation independently developed a soft magnetic under layer with a smooth interface using sputter deposition, created a nano-grained magnetic layer with fine magnetic particles and uniform crystalline orientation. This layer enabled Sony to successfully demonstrate the world’s highest areal recording density for tape storage media of 148 GB/in2. This areal density would make it possible to record more than 185 TB of data per data cartridge.
    • On May 19, 2014 Fujifilm in conjunction with IBM successfully demonstrated a record areal data density of 85.9 Gb/in2 on linear magnetic particulate tape using Fujifilm’s proprietary NANOCUBIC™ and Barium Ferrite (BaFe) particle technologies. This breakthrough in recording density equates to a standard LTO cartridge capable of storing up to 154 terabytes of uncompressed data, making it 62 times greater than today’s current LTO-6 cartridge capacity and projects a long and promising future for tape growth.
    • On Sept. 9, 2014 IBM announced LTFS LE version 2.1.4 4 extending LTFS (Linear Tape File System) tape library support.
    • On Sept. 10, 2014 the LTO Program Technology Provider Companies (TPCs), HP, IBM and Quantum, announced an extended roadmap which now includes LTO generations 9 and 10. The new generation guidelines call for compressed capacities of 62.5 TB for LTO-9 and 120 TB for generation LTO-10 and include compressed transfer rates of up to 1,770 MB/second for LTO-9 and a 2,750 MB/second for LTO-10. Each new generation will include read-and-write backwards compatibility with the prior generation as well as read compatibility with cartridges from two generations prior to protect investments and ease tape conversion and implementation.
    • On Oct. 6, 2014 IBM announced the TS1150 enterprise drive. Features of the TS1150 include a native data rate of up to 360 MB/sec versus the 250 MB/sec native data rate of the predecessor TS1140 and a native cartridge capacity of 10 TB compared to 4 TB on the TS1140. LTFS support was included.
    • On Nov. 6, 2014, HP announced a new release of StoreOpen Automation that delivers a solution for using LTFS in automation environments with Windows OS, available as a free download. This version complements their already existing support for Mac and Linux versions to help simplify integration of tape libraries to archiving solutions.

    Significant Technology Innovations Fuel Tape’s Future
    Development and manufacturing investment in tape library, drive, media and management software has effectively addressed the constant demand for improved reliability, higher capacity, power efficiency, ease of use and the lowest cost per GB of any storage solution. Below is a summary of tape’s value proposition followed by key metrics for each:

    • Tape drive reliability has surpassed disk drive reliability
    • Tape cartridge capacity (native) growth is on an unprecedented trajectory
    • Tape has a faster device data rate than disk
    • Tape has a much longer media life than any other digital storage medium
    • Tape’s functionality and ease of use is now greatly enhanced with LTFS
    • Tape requires significantly less energy consumption than any other digital storage technology
    • Tape storage has  a much lower acquisition cost and TCO than disk

    Reliability. Tape reliability levels have surpassed HDDs. Reliability levels for tape exceeds that of the most reliable disk drives by one to three orders of magnitude. The BER (Bit Error Rate – bits read per hard error) for enterprise tape is rated at 1×1019 and 1×1017 for LTO tape. This compares to 1×1016 for the most reliable enterprise Fibre Channel disk drive.

    Capacity and Data Rate. LTO-6 cartridges provide 2.5 TB capacity and more than double the compressed capacity of the preceding LTO-5 drive with a 14% data rate performance boost to 160 MB/sec. Enterprise tape has reached 8.5 TB native capacity and 252 MB/sec on the Oracle StorageTek T10000D and 10 TB native capacity and 360 MB/sec on the IBM TS1150. Tape cartridge capacities are expected to grow at unprecedented rates for the foreseeable future.

    Media Life. Manufacturers specifications indicate that enterprise and LTO tape media has a life span of 30 years or more while the average tape drive will be deployed 7 to 10 years before replacement. By comparison, the average disk drive is operational 3 to 5 years before replacement.

    LTFS Changes Rules for Tape Access. Compared to previous proprietary solutions, LTFS is an open tape format that stores files in application-independent, self-describing fashion, enabling the simple interchange of content across multiple platforms and workflows. LTFS is also being deployed in several innovative “Tape as NAS” active archive solutions that combine the cost benefits of tape with the ease of use and fast access times of NAS. The SNIA LTFS Technical Working Group has been formed to broaden cross–industry collaboration and continued technical development of the LTFS specification.

    TCOStudies. Tape’s widening cost advantage compared to other storage mediums makes it the most cost-effective technology for long-term data retention. The favorable economics (TCO, low energy consumption, reduced raised floor) and massive scalability have made tape the preferred medium for managing vast volumes of data. Several tape TCO studies are publicly available and the results consistently confirm a significant TCO advantage for tape compared to disk solutions.

    According to the Brad Johns Consulting Group, a TCO study for an LTFS-based ‘Tape as NAS’ solution totaled $1.1M compared with $7.0M for a disk-based unified storage solution.  This equates to a savings of over $5.9M over a 10-year period, which is more than 84 percent less than the equivalent amount for a storage system built on a 4 TB hard disk drive unified storage system.  From a slightly different perspective, this is a TCO savings of over $2,900/TB of data. Source: Johns, B. “A New Approach to Lowering the Cost of Storing File Archive Information,”.

    Another comprehensive TCO study by ESG (Enterprise Strategies Group) comparing an LTO-5 tape library system with a low-cost SATA disk system for backup using de-duplication (best case for disk) shows that disk deduplication has a 2-4x higher TCO than the tape system for backup over a 5 year period. The study revealed that disk has a TCO of 15x higher than tape for long-term data archiving.

    Select Case Studies Highlight Tape and Active Archive Solutions
    CyArk Is a non-profit foundation focused on the digital preservation of cultural heritage sites including places such as Mt. Rushmore, and Pompeii. CyArk predicted that their data archive would grow by 30 percent each year for the foreseeable future reaching one to two petabytes in five years. They needed a storage solution that was secure, scalable, and more cost-effective to provide the longevity required for these important historical assets. To meet this challenge CyArk implemented an active archive solution featuring LTO and LTFS technologies.

    Dream Works Animation a global Computer Graphic (CG) animation studio has implemented a reliable, cost-effective and scalable active archive solution to safeguard a 2 PB portfolio of finished movies and graphics, supporting a long-term asset preservation strategy. The studio’s comprehensive, tiered and converged active archive architecture, which spans software, disk and tape, saves the company time, money and reduces risk.

    LA Kings of the NHL rely extensively on digital video assets for marketing activities with team partners and for its broadcast affiliation with Fox Sports. Today, the Kings save about 200 GB of video per game for an 82 game regular season and are on pace to generate about 32-35 TB of new data per season. The King’s chose to implement Fujifilm’s Dternity NAS active archive appliance, an open LTFS based architecture. The Kings wanted an open source archiving solution which could outlast its original hardware while maintaining data integrity. Today with Dternity and LTFS, the Kings don’t have to decide what data to keep because they are able to cost-effectively save everything they might need in the future. 

    McDonald’s primary challenge was to create a digital video workflow that streamlines the management and distribution of their global video assets for their video production and post-production environment. McDonald’s implemented the Spectra T200 tape library with LTO-6 providing 250 TB of McDonald’s video production storage. Nightly, incremental backup jobs store their media assets into separate disk and LTO- 6 storage pools for easy backup, tracking and fast retrieval. This system design allows McDonald’s to effectively separate and manage their assets through the use of customized automation and data service policies.

    NCSA employs an Active Archive solution providing 100 percent of the nearline storage for the NCSA Blue Waters supercomputer, which is one of the world’s largest active file repositories stored on high capacity, highly reliable enterprise tape media. Using an active archive system along with enterprise tape and RAIT (Redundant Arrays of Inexpensive Tape) eliminates the need to duplicate tape data, which has led to dramatic cost savings.

    Queensland Brain Institute (QBI) is a leading center for neuroscience research.  QBI’s research focuses on the cellular and molecular mechanisms that regulate brain function to help develop new treatments for neurological and mental disorders.  QBI’s storage system has to scale extensively to store, protect, and access tens of terabytes of data daily to support cutting-edge research.  QBI choose an Oracle solution consisting of Oracle’s StorageTek SL3000 modular tape libraries with StorageTek T10000 enterprise tape drives.   The Oracle solution improved QBI’s ability to grow, attract world-leading scientists and meet stringent funding conditions.

    Looking Ahead to 2015 and Beyond
    The role tape serves in today’s modern data centers is expanding as IT executives and cloud service providers address new applications for tape that leverage its significant operational and cost advantages. This recognition is driving investment in new tape technologies and innovations with extended roadmaps, and it is expanding tape’s profile from its historical role in data backup to one that includes long-term archiving requiring cost-effective access to enormous quantities of stored data. Given the current and future trajectory of tape technology, data intensive markets such as big data, broadcast and entertainment, archive, scientific research, oil and gas exploration, surveillance, cloud, and HPC are expected to become significant beneficiaries of tape’s continued progress. Clearly the tremendous innovation, compelling value proposition and development activities demonstrate tape technology is not sitting still; expect this promising trend to continue in 2015 and beyond.

    What this means and summary

    Like it not tape is still alive being used along with the technology evolving with new enhancements as outlined above.

    Good to see the tape folks doing some marketing to get their story told and heard for those who are still interested.

    Does that mean I still use tape?

    Nope, I stopped using tape for local backups and archives well over a decade ago using disk to disk and disk to cloud.

    Does that mean I believe that tape is dead?

    Nope, I still believe that for some organizations and some usage scenarios it makes good sense, however like with most data storage related technologies, it’s not a one size or type of technology fits everything scenario value proposition.

    Cloud Conversations: Revisiting re:Invent 2014 and other AWS updates

    server storage I/O trends

    This is part one of a two-part series about Amazon Web Services (AWS) re:Invent 2014 and other recent cloud updates, read part two here.

    Revisiting re:Invent 2014 and other AWS updates

    AWS re:Invent 2014

    A few weeks ago I attended Amazon Web Service (AWS) re:Invent 2014 in Las Vegas for a few days. For those of you who have not yet attended this event, I recommend adding it to your agenda. If you have interest in compute servers, networking, storage, development tools or management of cloud (public, private, hybrid), virtualization and related topic themes, you should check out AWS re:invent.

    AWS made several announcements at re:invent including many around development tools, compute and data storage services. One of those to keep an eye on is cloud based Aurora relational database service that complement existing RDS tools. Aurora is positioned as an alternative to traditional SQL based transactional databases commonly found in enterprise environments (e.g. SQL Server among others).

    Some recent AWS announcements prior to re:Invent include

    AWS vCenter Portal

    Using the AWS Management Portal for vCenter adds a plug-in within your VMware vCenter to manage your AWS infrastructure. The vCenter for AWS plug-in includes support for AWS EC2 and Virtual Machine (VM) import to migrate your VMware VMs to AWS EC2, create VPC (Virtual Private Clouds) along with subnet’s. There is no cost for the plug-in, you simply pay for the underlying AWS resources consumed (e.g. EC2, EBS, S3). Learn more about AWS Management Portal for vCenter here, and download the OVA plug-in for vCenter here.

    AWS Database

    For those who are not familiar, AWS has a suite of database related services including SQL and no SQL based, simple to transactional to Petabyte (PB) scale data warehouses for big data and analytics. AWS offers the Relational Database Service (RDS) which is a suite of different database types, instances and services. RDS instance and types include SimpleDB, MySQL, Postgress, Oracle, SQL Server and the new AWS Aurora offering (read more below).  Other little data database and big data repository related offerings include DynamoDB (a non-SQL database), ElasticCache (in memory cache repository) and Redshift (large-scale data warehouse and big data repository).

    In addition to database services offered by AWS, you can also combine various AWS resources including EC2 compute, EBS and other storage offerings to create your own solution. For example there are various Amazon Machine Images (AMI’s) or pre-built operating systems and database tools available with EC2 as well as via the AWS Marketplace , such as MongoDB and Couchbase among others. For those not familiar with MongoDB, Couchbase, Cassandra, Riak along with other non SQL or alternative databases and key value repositories, check out Seven Databases in Seven Weeks in my book review of it here.

    Amazon RDS for Aurora

    Aurora is a new relational database offering part of the AWS RDS suite of services. Positioned as an alternative to commercial high-end database, Aurora is a cost-effective database engine compatible with MySQL. AWS is claiming 5x better performance than standard MySQL with Aurora while being resilient and durable. Learn more about Aurora which will be available in early 2015 and its current preview here.

    Amazon EC2 C4 instances

    AWS will be adding a new C4 instance as a next generation of EC2 compute instance based on Intel Xeon E5-2666 v3 (Haswell) processors. The Intel Xeon E5-2666 v3 processors run at a clock speed of 2.9 GHz providing the highest level of EC2 performance. AWS is targeting traditional High Performance Computing (HPC) along with other compute intensive workloads including analytics, gaming, and transcoding among others. Learn more AWS EC2 instances here, and view this Server and StorageIO EC2, EBS and associated AWS primer here.

    Amazon EC2 Container Service

    Containers such as those via Docker have become popular to support developers rapidly build as well as deploy scalable applications. AWS has added a new feature called EC2 Container Service that supports Docker using simple API’s. In addition to supporting Docker, EC2 Container Service is a high performance scalable container management service for distributed applications deployed on a cluster of EC2 instances. Similar to other EC2 services, EC2 Container Service leverages security groups, EBS volumes and Identity Access Management (IAM) roles along with scheduling placement of containers to meet your needs. Note that AWS is not alone in adding container and docker support with Microsoft Azure also having recently made some announcements, learn more about Azure and Docker here.
