How to test your HDD SSD AFA Hybrid or cloud storage

server storage data infrastructure i/o hdd ssd all flash array afa fundamentals

Updated 2/14/2018

Over at BizTech Magazine I have a new article 4 Ways to Performance Test Your New HDD or SSD that provides a quick guide to verifying or learning what the speed characteristic of your new storage device are capable of.

An out-take from the article used by BizTech as a "tease" is:

These four steps will help you evaluate new storage drives. And … psst … we included the metrics that matter.

Building off the basics, server storage I/O benchmark fundamentals

The four basic steps in the article are:

  • Plan what and how you are going to test (what’s applicable for you)
  • Decide on a benchmarking tool (learn about various tools here)
  • Test the test (find bugs, errors before a long running test)
  • Focus on metrics that matter (what’s important for your environment)

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).

aggregation causes aggravation
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.

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.

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.

Left MSI ProBox rear-view Right MSI ProBox front view

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.

MSI Probox internal view

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.

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. Check out the following links to read some extra perspectives about RAID and keep in mind, what might apply to enterprise may not be relevant for consumer or SMB and vise versa.

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.

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.

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.

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).

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

(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?

There are also these for doing board level connections

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.

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.

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.

What does server storage I/O scaling mean to you?

What does server storage I/O scaling mean to you?

Scaling means different things to various people depending on the context or what it is referring to.

For example, scaling can me having or doing more of something, or less as well as referring to how more, or less of something is implemented.

Scaling occurs in a couple of different dimensions and ways:

  • Application workload attributes – Performance, Availability, Capacity, Economics (PACE)
  • Stability without compromise or increased complexity
  • Dimension and direction – Scaling-up (vertical), scaling-out (horizontal), scaling-down

Scaling PACE – Performance Availability Capacity Economics

Often I hear people talk about scaling only in the context of space capacity. However there are aspects including performance, availability as well as scaling-up or scaling-out. Scaling from application workloads perspectives include four main group themes which are performance, availability, capacity and economics (as well as energy).

  • Performance – Transactions, IOP’s, bandwidth, response time, errors, quality of service
  • Availability – Accessibility, durability, reliability, HA, BC, DR, Backup/Restore, BR, data protection, security
  • Capacity – Space to store information or place for workload to run on a server, connectivity ports for networks
  • Economics – Capital and operating expenses, buy, rent, lease, subscription

Scaling with Stability

The latter of the above items should be thought of more in terms of a by-product, result or goal for implementing scaling. Scaling should not result in a compromise of some other attribute such as increasing performance and loss of capacity or increased complexity. Scaling with stability also means that as you scale in some direction, or across some attribute (e.g. PACE), there should not be a corresponding increase in complexity of management, or loss of performance and availability. To use a popular buzz-term scaling with stability means performance, availability, capacity, economics should scale linear with their capabilities or perhaps cost less.

Scaling directions: Scaling-up, scaling-down, scaling-out

server and storage i/o scale options

Some examples of scaling in different directions include:

  • Scaling-up (vertical scaling with bigger or faster)
  • Scaling-down (vertical scaling with less)
  • Scaling-out (horizontal scaling with more of what being scaled)
  • Scaling-up and out (combines vertical and horizontal)

Of course you can combine the above in various combinations such as the example of scaling up and out, as well as apply different names and nomenclature to see your needs or preferences. The following are a closer look at the above with some simple examples.

server and storage i/o scale up
Example of scaling up (vertically)

server and storage i/o scale down
Example of scaling-down (e.g. for smaller scenarios)

server and storage i/o scale out
Example of scaling-out (horizontally)

server and storage i/o scale out
Example of scaling-out and up(horizontally and vertical)

Summary and what this means

There are many aspects to scaling, as well as side-effects or impacts as a result of scaling.

Scaling can refer to different workload attributes as well as how to support those applications.

Regardless of what you view scaling as meaning, keep in mind the context of where and when it is used and that others might have another scale view of scale.

Lenovo ThinkServer TD340 StorageIO lab Review

Storage I/O trends

Lenovo ThinkServer TD340 Server and StorageIO lab Review

Earlier this year I did a review of the Lenovo ThinkServer TS140 in the StorageIO Labs (see the review here), in fact I ended up buying a TS140 after the review, and a few months back picked up another one. This StorageIOlab review looks at the Lenovo ThinkServer TD340 Tower Server which besides having a larger model number than the TS140, it also has a lot more capabilities (server compute, memory, I/O slots and internal hot-swap storage bays. Pricing varies depending on specific configuration options, however at the time of this post Lenovo was advertising a starting price of $1,509 USD for a specific configuration here. You will need to select different options to decide your specific cost.

The TD340 is one of the servers that Lenovo has had prior to its acquisition of IBM x86 server business that you can read about here. Note that the Lenovo acquisition of the IBM xSeries business group has begun as of early October 2014 and is expected to be completed across different countries in early 2015. Read more about the IBM xSeries business unit here, here and here.

The Lenovo TD340 Experience

Lets start with the overall experience which was very easy other than deciding what make and model to try. This includes going from first answering some questions to get the process moving, agreeing to keep the equipment safe, secure, insured as well as not damaging anything. Part of the process also involved answering some configuration related questions and shortly there after a large box from Lenovo arrived.

TD340 is ready for use
TD340 with Keyboard and Mouse (Monitor and keyboard not included)

One of the reasons I have a photo of the TD340 on a desk is that I initially put it in an office environment similar to what I did with the TS140 as Lenovo claimed it would be quiet enough to do so. I was not surprised and indeed the TD340 is quiet enough to be used where you would normally find a workstation or mini-tower. By being so quiet the TD340 is a good fit for environments that need a server that has to go into an office environment as opposed to a server or networking room.

Welcome to the TD340

Speeds and Feeds

The TD340 that I tested was a Machine type 7087 model 002RUX which included 4 x 16GB DIMMs and both processor sockets occupied.

You can view the Lenovo TD340 data sheet with more speeds and feeds here, however the following is a summary.

  • Operating systems support include various Windows Servers (2008-2012 R2), SUSE, RHEL, Citrix XenServer and VMware ESXi
  • Form factor is 5U tower with weight starting at 62 pounds depending on how configured
  • Processors include support for up to two (2) Intel E5-2400 v2 series
  • Memory includes 12 DDR3 DRAM DIMM slots (LV RDIMM and UDIMM) for up to 129GB.
  • Expansion slots vary depending on if a single or dual cpu socket. Single CPU socket installed has 1 x PCIe Gen3 FH/HL x8 mechanical, x4 electrical, 1 x PCIe Gen3
  • FH/HL x16 mechanical, x16 electrical and a single PCI 32bit/33 MHz FH/HL slot. With two CPU sockets installed extra PCIe slots are enabled. These include single x PCIe GEN3: FH/HL x8 mechanical, x4 electrical, single x PCIe GEN3: FH/HL x16 mechanical, x16 electrical, three x PCIe GEN3: FH/HL x8 mechanical, x8 electrical and a single PCI 5V 32-bit/33 MHz: FH/HL
  • Two 5.25” media bays for CD or DVDs or other devices
  • Integrated ThinkServer RAID (0/1/10/5) with optional RAID adapter models
  • Internal storage varies depending on model including up to eight (8) x 3.5” hot swap drives or 16 x 2.5” hot swap drives (HDD’s or SSDs).
  • Storage space capacity varies by the type and size of the drives being used.
  • Networking interfaces include two (2) x GbE
  • Power supply options include single 625 watt or 800 watt, or 1+1 redundant hot-swap 800 watt, five fixed fans.
  • Management tools include ThinkServer Management Module and diagnostics

What Did I do with the TD340

After initial check out in an office type environment, I moved the TD340 into the lab area where it joined other servers to be used for various things.

Some of those activities included using the Windows Server 2012 Essentials along with associated admin activities as well as installing VMware ESXi 5.5.

TD340 is ready for use
TD340 with Keyboard and Mouse (Monitor and keyboard not included)

What I liked

Unbelievably quiet which may not seem like a big deal, however if you are looking to deploy a server or system into a small office workspace, this becomes an important considerations. Otoh, if you are a power user and want a robust server that can be installed into a home media entertainment system, well, this might be a nice to have consideration ;). Speaking of IO slots, naturally I’m interested in Server Storage I/O so having multiple slots is a must have, along with the processor that is multi-core (pretty much standard these days) along with VT and EP for supporting VMware (these were disabled in the BIOS however that was an easy fix).

What I did not like

The only thing I did not like was that I ran into a compatibility issue trying to use a LSI 9300 series 12Gb SAS HBA which Lenovo is aware of, and perhaps has even addressed by now. What I ran into is that the adapters work however I was not able to get the full performance out of the adapters as compared to on other systems including my slower Lenovo TS140s.

Summary

Overall I give Lenovo and the TD340 an "B+" which would have been an "A" had I not gotten myself into a BIOS situation or been able to run the 12Gbps SAS PCIe Gen 3 cards at full speed. Likewise the Lenovo service and support also helped to improve on the experience. Otoh, if you are simply going to use the TD340 in a normal out of the box mode without customizing to add your own adapters or install your own operating system or Hypervisors (beyond those that are supplied as part of the install setup tool kit), you may have an "A" or "A+" experience with the TD340.

Would I recommend the TD340 to others? Yes for those who need this type and class of server for Windows, *nix, Hyper-V or VMware environments.

Would I buy a TD340 for myself? Maybe if that is the size and type of system I need, however I have my eye on something bigger. On the other hand for those who need a good value server for a SMB or ROBO environment with room to grow, the TD340 should be on your shopping list to compare with other solutions.

Disclosure: Thanks to the folks at Lenovo for sending and making the TD340 available for review and a hands on test experience including covering the cost of shipping both ways (the unit should now be back in your possession). Thus this is not a sponsored post as Lenovo is not paying for this (they did loan the server and covered two-way shipping), nor am I paying them, however I have bought some of their servers in the past for the StorageIOLab environment that are companions to some Dell and HP servers that I have also purchased.

    VMware VVOLs storage I/O fundementals (Part 1)

    VMware VVOL’s storage I/O fundamentals (Part I)

    Note that this is a three part series with the first piece here (e.g. Are VMware VVOL’s in your virtual server and storage I/O future?), the second piece here (e.g.VMware VVOL’s and storage I/O fundamentals Part 1) and the third piece here (e.g. VMware VVOL’s and storage I/O fundamentals Part 2).

    Some of you may already be participating in the VMware beta of VVOL involving one of the initial storage vendors also in the beta program.

    Ok, now let’s go a bit deeper, however if you want some good music to listen to while reading this, check out @BruceRave GoDeepMusic.Net and shows here.

    Instead of a VM host accessing its virtual disk (aka VMDK) which is stored in a VMFS formatted data store (part of ESXi hypervisor) built on top of a SCSI LUN (e.g. SAS, SATA, iSCSI, Fibre Channel aka FC, FCoE aka FC over Ethernet, IBA/SRP, etc) or an NFS file system presented by a storage system (or appliance), VVOL’s push more functionality and visibility down into the storage system. VVOL’s shift more intelligence and work from the hypervisor down into the storage system. Instead of a storage system simply presenting a SCSI LUN or NFS mount point and having limited (coarse) to no visibility into how the underlying storage bits, bytes as well as blocks are being used, storage systems gain more awareness.

    Keep in mind that even files and objects still get ultimately mapped to pages and blocks aka sectors even on nand flash-based SSD’s. However also keep an eye on some new technology such as the Seagate Kinetic drive that instead of responding to SCSI block based commands, leverage object API’s and associated software on servers. Read more about these emerging trends here and here at objectstoragecenter.com.

    With a normal SCSI LUN the underlying storage system has no knowledge of how the upper level operating system, hypervisor, file system or application such as a database (doing raw IO) is allocating the pages or blocks of memory aka storage. It is up to the upper level storage and data management tools to map from objects and files to the corresponding extents, pages and logical block address (LBA) understood by the storage system. In the case of a NAS solution, there is a layer of abstractions placed over the underlying block storage handling file management and the associated file to LBA mapping activity.

    Storage I/O basics
    Storage I/O and IOP basics and addressing: LBA’s and LBN’s

    Getting back to VVOL, instead of simply presenting a LUN which is essentially a linear range of LBA’s (think of a big table or array) that the hypervisor then manages data placement and access, the storage system now gains insight into what LBA’s correspond to various entities such as a VMDK or VMX, log, clone, swap or other VMware objects. With this more insight, storage systems can now do native and more granular functions such as clone, replication, snapshot among others as opposed to simply working on a coarse LUN basis. The similar concepts extend over to NAS NFS based access. Granted, there are more to VVOL’s including ability to get the underlying storage system more closely integrated with the virtual machine, hypervisor and associated management including supported service manage and classes or categories of service across performance, availability, capacity, economics.

    What about VVOL, VAAI and VASA?

    VVOL’s are building from earlier VMware initiatives including VAAI and VASA. With VAAI, VMware hypervisor’s can off-load common functions to storage systems that support features such as copy, clone, zero copy among others like how a computer can off-load graphics processing to a graphics card if present.

    VASA however provides a means for visibility, insight and awareness between the hypervisor and its associated management (e.g. vCenter etc) as well as the storage system. This includes storage systems being able to communicate and publish to VMware its capabilities for storage space capacity, availability, performance and configuration among other things.

    With VVOL’s VASA gets leveraged for unidirectional (e.g. two-way) communication where VMware hypervisor and management tools can tell the storage system of things, configuration, activities to do among others. Hence why VASA is important to have in your VMware CASA.

    What’s this object storage stuff?

    VVOL’s are a form of object storage access in that they differ from traditional block (LUN’s) and files (NAS volumes/mount points). However, keep in mind that not all object storage are the same as there are object storage access and architectures.

    object storage
    Object Storage basics, generalities and block file relationships

    Avoid making the mistake of when you hear object storage that means ANSI T10 (the folks that manage the SCSI command specifications) Object Storage Device (OSD) or something else. There are many different types of underlying object storage architectures some with block and file as well as object access front ends. Likewise there are many different types of object access that sit on top of object architectures as well as traditional storage system.

    Object storage I/O
    An example of how some object storage gets accessed (not VMware specific)

    Also keep in mind that there are many different types of object access mechanism including HTTP Rest based, S3 (e.g. a common industry defacto standard based on Amazon Simple Storage Service), SNIA CDMI, SOAP, Torrent, XAM, JSON, XML, DICOM, IL7 just to name a few, not to mention various programmatic bindings or application specific implementations and API’s.

    April and May 2014 Server and StorageIO Update newsletter


    Server and StorageIO Update newsletter – April and May 2014

    Welcome to the April and May 2014 edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics.

    The good news is that while spring is running late (as is this newsletter ;) here in the Stillwater MN area as well as other parts of the world, both are finally here. To say that a lot has been going on and things busy would be an understatement, however that is probably also the situation with you as well. So what has been going on during April and May 2014?

    Industry and Technology Updates

    Sony and Fujifilm (with their partner IBM) are trading marketing and proof of concept (POC) lab material in the efforts to show tape is still alive for data storage. Sony announced a month or so ago that it was moving the bar to 185TB per tape (without dedupe). Not to be out done, Fujifilm announced in late May that they in conjunction with IBM have a POC for a 154 TB LTO in the works.

    Greg Schulz Storage I/OGreg Schulz on break
    On the Hard Disk Drive (HDD) front, Seagate released a new 6TB device that they claim to be fast. I asked Seagate to send me one of the drives to see how fast it really is vs. their claims. While I have not completed all tests yet, what I can tell you is that the 6TB 3.5" 12Gbps SAS 7.2K RPM drive is like an american football linebacker or fullback. Its big, bulky, high-capacity, resilient with 10 to the 15 bit error rate (higher than normal high-capacity HDD’s) and fast.

    Sure the 6TB HDD is not in the speed race of a quick SSD or SSHD or 15K, however I was surprised at just how fast it is for its space capacity. Watch for a follow-up review in the not so distant future and if a WD 6TB drive were to show up on my door step can give some perspectives on that as well.

    As for SSD, they are following the trend paths of tape and HDD’s of increasing in space capacity, coming down in price and improving on resiliency. While I see HDD and even tape surviving for some time, granted in different roles, I’m also a firm believer that flash SSD in some form are in your future. The question is how much, when, where, with what and from whom. Needless to say there is plenty of SSD related hardware and software activity occurring in the StorageIO labs ;).

    Vendors and revenue earnings, is there storage slowdown?

    In other industry news and activity, vendor quarterly earnings are out and there is mixed information (see this recent post of if there is an information recession). IBM is one of those who have announced lowered storage related revenues as NetApp had mixed results (as did other vendors). In addition IBM is officially saying they are finally dropping the NetApp (FAS/ONTAP) based N series (was originally reported a week or so ago via Bloomberg). Note that IBM will continue to OEM NetApp E series (e.g. Engenio based). Some of you might remember (or do a Google search) that IBM indicated a few years back that it was De emphasizing the N series or moving away from it. Perhaps this time they really mean it while NetApp could move to embrace those VAR’s and IBM business partners to sell NetApp vs. IBM branded versions of the product. Here are some more perspectives appearing in SearchStorage. Watch for more about NetApp in a future follow-up post.

    In some other industry news, you might remember back in the February StorageIO update newsletter there was mention of Avago buying LSI. Now Avago is selling the flash business of LSI to Seagate for about $450M USD in the ongoing flash dance for cache and cash.

    Staying busy is a good thing

    What have I been doing during April and May 2014 to stay busy besides getting ready for spring and summer fun including in and around the water?

    Via InformationSecurityBuzz:  Dark Territories MH370 Do You Know Where Your Information Is? We still dont know 100% where the missing Malaysian airlines flight 370 is which amplifies the fact that there are still dar territories or gaps in coverage in this large world. Likewise there are gaps in coverage in many IT environments yet tools and technologies are available to gain better situational awareness and insight.

    Via The Virtualization Practice: This piece looks at the EMC ViPR V1.1 and SRM V3.0 (Software Defined Storage Management) announcements from earlier this year, along with links to earlier announcement and technology analysis. Note that EMC announced May 5, 2014 ViPR 2.0 along with their new Elastic Cloud Storage Appliance (ECS) among other enhancements at EMC World. Additional perspectives on ViPR 2.0, Elastic Cloud Storage Appliance and EMCworld announcement summary analysis can be found here in this video (with text) that I did (produced via TechTarget) while at EMCworld 2014. Watch for more coverage of ViPR 2.0 and other related new as well as updated items from EMCworld 2014 in upcoming posts, articles and commentary.

    Via InfoStor: Data Archiving: Life Beyond Compliance. Today many people think or assume based on what they hear that Archiving is only for regulatory archiving. Meanwhile some of you may remember a time before the regulatory compliance era of the early 2000s when Archiving was used as a general purpose tool, technology and solution to many IT data management storage challenges. This piece I did over at InfoStor looks at Data Archiving: Life Beyond Compliance and how Archiving is also a key technology that are part of Data Footprint Reduction (DFR) that also includes compression, dedupe, thin provisioning amount other techniques and tools. Here is a related Email Archiving piece (beyond compliance) from over at StateTech along with Practical tips in a piece over at VMware Communities.

    Enterprise SSHD and Flash SSD – Better Together – Part of an Enterprise Tiered Storage Strategy The question to ask yourself is not if flash Solid State Device (SSD) technologies are in your future. Instead the questions are when, where, using what, how to configure and related themes. SSD including traditional DRAM and NAND flash-based technologies are like real estate where location matters; however, there are different types of properties to meet various needs.

    This means leveraging different types of NAND flash SSD technologies in different locations in a complementary and cooperative aka hybrid way. In this StorageIO Industry Trends Perspective thought leadership white paper we look at how enterprise class Solid State Hybrid Drives (SSHD) and how they address current and next generation tiered storage for virtual, cloud, traditional Little and Big Data infrastructure environments. This includes providing proof points running various workloads including Database TPC-B, TPC-E and Microsoft Exchange in the StorageIO Labscomparing SSHD, SSD and different HDDs.

    Lenovo TS140 Server and Storage I/O Review

    Storage I/O trends

    Lenovo TS140 Server and Storage I/O Review

    This is a review that looks at my recent hands on experiences in using a TS140 (Model MT-M 70A4 – 001RUS) pedestal (aka tower) server that the Lenovo folks sent to me to use for a month or so. The TS140 is one of the servers that Lenovo had prior to its acquisition of IBM x86 server business that you can read about here.

    The Lenovo TS140 Experience

    Lets start with the overall experience which was very easy and good. This includes going from initial answering some questions to get the process moving, agreeing to keep the equipment safe, secure, insured as well as not damaging anything (this was not a tear down and rip it apart into pieces trial).

    Part of the process also involved answering some configuration related questions and shortly there after a large box from Lenovo arrived. Turns out it was a box (server hardware) inside of a Lenovo box, that was inside a slightly larger unmarked shipping box (see larger box in the background).

    TS140 with Keyboard and Mouse (Monitor not included)

    One of the reasons I have a photo of the TS140 on a desk is that I initially put it in an office environment as Lenovo claimed it would be quiet enough to do so. I was not surprised and indeed the TS140 is quiet enough to be used where you would normally find a workstation or mini-tower. By being so quiet the TS140 is a good fit for environments that need a small or starter server that has to go into an office environment as opposed to a server or networking room. For those who are into mounting servers, there is the option for placing the TS140 on its side into a cabinet or rack.

    Part II: What I did with Lenovo TS140 in my Server and Storage I/O Review

    Storage I/O trends

    Part II: Lenovo TS140 Server and Storage I/O Review


    This is the second of a two-part post series on my recent experiences with a Lenovo TS140 Server, you can read part I here.

    What Did I do with the TS140

    After initial check out in an office type environment, I moved the TS140 into the lab area where it joined other servers to be used for various things.

    Some of those activities included using the Windows Server 2012 Essentials along with associated admin activities. Also, I also installed VMware ESXi 5.5 and ran into a few surprises. One of those was that I needed to apply an update to VMware drivers to support the onboard Intel NIC, as well as enable VT and EP modes for virtualization to assist via the BIOS. The biggest surprise was that I discovered I could not install VMware onto an internal drive attached via one of the internal SATA ports which turns out to be a BIOS firmware issue.

    Lenovo confirmed this when I brought it to their attention, and the workaround is to use USB to install VMware onto a USB flash SSD thumb drive, or other USB attached drive or to use external storage via an adapter. As of this time Lenovo is aware of the VMware issue, however, no date for new BIOS or firmware is available. Speaking of BIOS, I did notice that there was some newer BIOS and firmware available (FBKT70AUS December 2013) than what was installed (FB48A August of 2013). So I went ahead and did this upgrade which was a smooth, quick and easy process. The process included going to the Lenovo site (see resource links below), selecting the applicable download, and then installing it following the directions.

    Since I was going to install various PCIe SAS adapters into the TS140 attached to external SAS and SATA storage, this was not a big issue, more of an inconvenience Likewise for using storage mounted internally the workaround is to use an SAS or SATA adapter with internal ports (or cable). Speaking of USB workarounds, have a HDD, HHDD, SSHD or SSD that is a SATA device and need to attach it to USB, then get one of these cables. Note that there are USB 3.0 and USB 2.0 cables (see below) available so choose wisely.

    USB to SATA adapter cable

    In addition to running various VMware-based workloads with different guest VMs.

    I also ran FUTREMARK PCmark (btw, if you do not have this in your server storage I/O toolbox it should be) to gauge the systems performance. As mentioned the TS140 is quiet. However, it also has good performance depending on what processor you select. Note that while the TS140 has a list price as of the time of this post under $400 USD, that will change depending on which processor, amount of memory, software and other options you choose.

    Composite score2274
    Compute11530
    System Storage2429
    Secondary Storage2428
    Productivity1682
    Lightweight2137

    PCmark results are shown above for the Windows Server 2012 system (non-virtualized) configured as shipped and received from Lenovo.

    What I liked

    Unbelievably quiet which may not seem like a big deal, however, if you are looking to deploy a server or system into a small office workspace, this becomes an important considerations. Otoh, if you are a power user and want a robust server that can be installed into a home media entertainment system, well, this might be a nice to have consideration ;).

    Something else that I liked is that the TS140 with the E3-1220 v3 family of processor supports PCIe G3 adapters which are useful if you are going to be using 10GbE cards or 12Gbs SAS and faster cards to move lots of data, support more IOPs or reduce response time latency.

    In addition, while only 4 DIMM slots is not very much, its more than what some other similar focused systems have, plus with large capacity DIMMs, you can still get a nice system, or two, or three or four for a cluster at a good price or value (Hmm, VSAN anybody?). Also while not a big item, the TS140 did not require ordering an HDD or SSD if you are not also ordering software the system for a diskless system and have your own.

    Speaking of IO slots, naturally I’m interested in Server Storage I/O so having multiple slots is a must have, along with the processor that is quad core (pretty much standard these days) along with VT and EP for supporting VMware (these were disabled in the BIOS. However, that was an easy fix).

    Then there is the price as of this posting starting at $379 USD which is a bare bones system (e.g. minimal memory, basic processor, no software) whose price increases as you add more items. What I like about this price is that it has the PCIe G3 slot as well as other PCIe G2 slots for expansion meaning I can install 12Gbps (or 6Gbps) SAS storage I/O adapters, or other PCIe cards including SSD, RAID, 10GbE CNA or other cards to meet various needs including software defined storage.

    What I did not like

    I would like to have had at least six vs. four DIMM slots, however keeping in mind the price point of where this system is positioned, not to mention what you could do with it thinking outside of the box, I’m fine with only 4 x DIMM. Space for more internal storage would be nice, however, if that is what you need, then there are the larger Lenovo models to look at. By the way, thinking outside of the box, could you do something like a Hadoop, OpenStack, Object Storage, VMware VSAN or other cluster with these in addition to using as a Windows Server?

    Yup.

    Granted you won’t have as much internal storage, as the TS140 only has two fixed drive slots (for more storage there is the model TD340 among others).

    However it is not that difficult to add more (not Lenovo endorsed) by adding a StarTech enclosure like I did with my other systems (see here). Oh and those extra PCIe slots, that’s where a 12Gbs (or 6Gbps) adapter comes into play while leaving room for GbE cards and PCIe SSD cards. Btw not sure what to do with that PCIe x1 slot, that’s a good place for a dual GbE NIC to add more networking ports or an SATA adapter for attaching to larger capacity slower drives.

    If VMware is not a requirement, and you need a good entry level server for a large SOHO or small SMB environment, or, if you are looking to add a flexible server to a lab or for other things the TS140 is good (see disclosure below) and quiet.

    Otoh as mentioned, there is a current issue with the BIOS/firmware with the TS140 involving VMware (tried ESXi 5 & 5.5).

    However I did find a workaround which is that the current TS140 BIOS/Firmware does work with VMware if you install onto a USB drive, and then use external SAS, SATA or other accessible storage which is how I ended up using it.

    Lenovo TS140 resources include

  • TS140 Lenovo ordering website
  • TS140 Data and Spec Sheet (PDF here)
  • Lenovo ThinkServer TS140 Manual (PDF here)
  • Intel E3-1200 v3 processors capabilities (Web page here)
  • Lenovo Drivers and Software (Web page here)
  • Lenovo BIOS and Drivers (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)
  • My experience from a couple years ago dealing with Lenovo support for a laptop issue
  • Summary

    Disclosure: Lenovo loaned the TS140 to me for just under two months including covering shipping costs at no charge (to them or to me) hence this is not a sponsored post or review. On the other hand I have placed an order for a new TS140 similar to the one tested that I bought on-line from Lenovo.

    This new TS140 server that I bought joins the Dell Inspiron I added late last year (read more about that here) as well as other HP and Dell systems.

    Overall I give the Lenovo TS140 an provisional "A" which would be a solid "A" once the BIOS/firmware issue mentioned above is resolved for VMware. Otoh, if you are not concerned about using the TS140 for VMware (or can do a work around), then consider it as an "A".

    As mentioned above, I liked it so much I actually bought one to add to my collection.

    Ok, nuff said (for now)
