Data Infrastructure and IT Industry Activity Trends

Data Infrastructure Data Protection and Backup BC BR DR HA Security

World Backup day is coming up on March 31 which is a good time to remember to verify and validate that your data protection is working as intended. On one hand I think it is a good idea to call out the importance of making sure your data is protected including backed up.

On the other hand data protection is not a once a year, rather a year around, 7 x 24 x 365 day focus. Also the focus needs to be on more than just backup, rather, all aspects of data protection from archiving to business continuance (BC), business resiliency (BR), disaster recovery (DR), always on, always accessible, along with security and recovery.

Some data spring thoughts, perspectives and reminders. Data lakes may swell beyond their banks causing rivers of data to flood as they flow into larger reservoirs, great data lakes, gulfs of data, seas and oceans of data. Granted, some of that data will be inactive cold parked like glaciers while others semi-active floating around like icebergs. Hopefully your data is stored on durable storage solutions or services and does not melt.

Data Infrastructure Server Storage I/O flash SSD NVMe
Various NAND Flash SSD devices and SAS, SATA, NVMe, M.2 interfaces

Non-Volatile Memory (NVM) including various solid state device (SSD) mediums (e.g. nand flash, 3D XPoint, MRAM among others), packaging (drives, PCIe Add in cars [AiC] along with entire systems, appliances or arrays). Also part of the continue evolution of NVM, SSD and other persistent memories (PM) including storage class memories (SCM) are different access protocol interfaces.

Keep in mind that there is a difference between NVM (medium) and NVMe (access), NVM is the generic category of mediums or media and devices such as nand flash, nvram, 3D XPoint among others SCM (and PMs). In other words, NVM is what data devices use for storing data, NVMe is how devices and systems are accessed. NVMe and its variations is how NVM, SSD, PM, SCM media and devices get accessed locally, as well as over network fabrics (e.g. NVMe-oF an FC-NVMe).

NVMe continues to evolve including with networked fabric variations such as RDMA based NVMe over Fabric (NVMe-oF), along with Fibre Channel based (FC-NVMe). The Fibre Channel Industry Association trade group recently held its second multi-vendor plugfest in support of NVMe over Fibre Channel.

Has Object Storage failed to live up to its industry hype lacking traction? Or, is object storage (also known as blobs) progressing with customer adoption and deployment on normal realistic timelines? Recently I have seen some industry comments about object storage not catching on with customers or failing to live up to its hyped expectation. IMHO object storage is very much alive along with block, file, table (e.g. database SQL and NoSQL repositories), message/queue among others, as well as emerging blockchain aka data exchanges.

Various Industry and Customer Adoption Deployment timeline
Various Industry and Customer Adoption Deployment Timeline (Via: StorageIOblog.com)

An issue with object storage is that it is still new, still evolving, many IT environments applications do not yet speak or access objects and blobs natively. Likewise as is often the case, industry adoption and deployment is usually early and short term around the hype, vs. the longer cycle of customer adoption and deployment. The downside for those who only focus on object storage (or blobs) is that they may be under pressure to do things short term instead of adjusting to customer cycles which take longer, however real adoption and deployment also last longer.

While the hype and industry buzz around object storage (and blobs) may have faded, customer adoption continues and is here to stay, along with block, file among others, learn more at www.objectstoragecenter.com. Also keep in mind that there is a difference between industry and customer adoption along with deployment.

Some recent Industry Activities, Trends, News and Announcements include:

In case you missed it, Amazon Web Services (e.g. AWS) announced EKS (Elastic Kubernetes Service) which as its name implies, is an easy to use and manage Kubernetes (containers, serverless data infrastructure) running on AWS. AWS joins others including Microsoft Azure Kubernetes Services (AKS), Googles Kubernetes Engine, EasyStack (ESContainer for openstack and Kubernetes),VMware Pivotal Container Service (PKS) among others. What this means is that in the container serverless data infrastructure ecosystem Kubernetes container management (orchestration platform) is gaining in both industry as well as customer adoption along with deployment.

What this all means and wrap-up

Data Infrastructures are what exists inside physical data centers spanning cloud, converged, hyper-converged, virtual, serverless and other software defined as well as legacy environments. The fundamental role of data infrastructures comprising server (compute), storage, I/O networking hardware, software, services defined by management tools, best practices and policies is to provide a platform for applications along with their data to deliver information services. With March 31 being world backup day, also focus on making sure that on April 1st you are not a fool trying to recover from a bad data protection copy. With the continued movement to flash SSD along with other forms of storage class memory (SCM) and persistent memories (PM), data moves at a faster rate meaning data protection is even more important to get you out of trouble as fast as you get into issues.

New family of Intel Xeon Scalable Processors enable software defined data infrastructures (SDDI) and SDDC

Intel Xeon Scalable Processors SDDI and SDDC

server storage I/O data infrastructure trends

Today Intel announced a new family of Xeon Scalable Processors (aka Purely) that for some workloads Intel claims to be on average of 1.65x faster than their predecessors. Note your real improvement will vary based on workload, configuration, benchmark testing, type of processor, memory, and many other server storage I/O performance considerations.

Intel Scalable Xeon Processors
Image via Intel.com

In general the new Intel Xeon Scalable Processors enable legacy and software defined data infrastructures (SDDI), along with software defined data centers (SDDC), cloud and other environments to support expanding workloads more efficiently as well as effectively (e.g. boosting productivity).

Data Infrastructures and workloads

Some target application and environment workloads Intel is positioning these new processors for includes among others:

  • Machine Learning (ML), Artificial Intelligence (AI), advanced analytics, deep learning and big data
  • Networking including software defined network (SDN) and network function virtualization (NFV)
  • Cloud and Virtualization including Azure Stack, Docker and Kubernetes containers, Hyper-V, KVM, OpenStack VMware vSphere, KVM among others
  • High Performance Compute (HPC) and High Productivity Compute (e.g. the other HPC)
  • Storage including legacy and emerging software defined storage software deployed as appliances, systems or server less deployment modes.

Features of the new Intel Xeon Scalable Processors include:

  • New core micro architecture with interconnects and on die memory controllers
  • Sockets (processors) scalable up to 28 cores
  • Improved networking performance using Quick Assist and Data Plane Development Kit (DPDK)
  • Leverages Intel Quick Assist Technology for CPU offload of compute intensive functions including I/O networking, security, AI, ML, big data, analytics and storage functions. Functions that benefit from Quick Assist include cryptography, encryption, authentication, cipher operations, digital signatures, key exchange, loss less data compression and data footprint reduction along with data at rest encryption (DARE).
  • Optane Non-Volatile Dual Inline Memory Module (NVDIMM) for storage class memory (SCM) also referred to by some as Persistent Memory (PM), not to be confused with Physical Machine (PM).
  • Supports Advanced Vector Extensions 512  (AVX-512) for HPC and other workloads
  • Optional Omni-Path Fabrics in addition to 1/10Gb Ethernet among other I/O options
  • Six memory channels supporting up to 6TB of RDIMM with multi socket systems
  • From two to eight  sockets per node (system)
  • Systems support PCIe 3.x (some supporting x4 based M.2 interconnects)

Note that exact speeds, feeds, slots and watts will vary by specific server model and vendor options. Also note that some server system solutions have two or more nodes (e.g. two or more real servers) in a single package not to be confused with two or more sockets per node (system or motherboard). Refer to the where to learn more section below for links to Intel benchmarks and other resources.

Software Defined Data Infrastructures, SDDC, SDX and SDDI

What About Speeds and Feeds

Watch for and check out the various Intel partners who have or will be announcing their new server compute platforms based on Intel Xeon Scalable Processors. Each of the different vendors will have various speeds and feeds options that build on the fundamental Intel Xeon Scalable Processor capabilities.

For example Dell EMC announced their 14G server platforms at the May 2017 Dell EMC World event with details to follow (e.g. after the Intel announcements).

Some things to keep in mind include the amount of DDR4 DRAM (or Optane NVDIMM) will vary by vendors server platform configuration, motherboards, several sockets and DIMM slots. Also keep in mind the differences between registered (e.g. buffered RDIMM) that give good capacity and great performance, and load reduced DIMM (LRDIMM) that have great capacity and ok performance.

Various nvme options

What about NVMe

It’s there as these systems like previous Intel models support NVMe devices via PCIe 3.x slots, and some vendor solutions also supporting M.2 x4 physical interconnects as well.

Note that Broadcom formerly known as Avago and LSI recently announced PCIe based RAID and adapter cards that support NVMe attached devices in addition to SAS and SATA.

server storage data infrastructure sddi

What About Intel and Storage

In case you have not connected the dots yet, the Intel Xeon Scalable Processor based server (aka compute) systems are also a fundamental platform for storage systems, services, solutions, appliances along with tin-wrapped software.

What this means is that the Intel Xeon Scalable Processors based systems can be used for deploying legacy as well as new and emerging software-defined storage software solutions. This also means that the Intel platforms can be used to support SDDC, SDDI, SDX, SDI as well as other forms of legacy and software-defined data infrastructures along with cloud, virtual, container, server less among other modes of deployment.

Image Via Intel.com

Moving beyond server and compute platforms, there is another tie to storage as part of this recent as well as other Intel announcements. Just a few weeks ago Intel announced 64 layer triple level cell (TLC) 3D NAND solutions positioned for the client market (laptop, workstations, tablets, thin clients). Intel with that announcement increased the traditional aerial density (e.g. bits per square inch or cm) as well as boosting the number of layers (stacking more bits as well).

The net result is not only more bits per square inch, also more per cubic inch or cm. This is all part of a continued evolution of NAND flash including from 2D to 3D, MCL to TLC, 32 to 64 layer.  In other words, NAND flash-based Solid State Devices (SSDs) are very much still a relevant and continue to be enhanced technology even with the emerging 3D XPoint and Optane (also available via Amazon in M.2) in the wings.

server memory evolution
Via Intel and Micron (3D XPoint launch)

Keep in mind that NAND flash-based technologies were announced almost 20 years ago (1999), and are still evolving. 3D XPoint announced two years ago, along with other emerging storage class memories (SCM), non-volatile memory (NVM) and persistent memory (PM) devices are part of the future as is 3D NAND (among others). Speaking of 3D XPoint and Optane, Intel had announcements about that in the past as well.

Where To Learn More

Learn more about Intel Xeon Scalable Processors along with related technology, trends, tools, techniques and tips with the following links.

What This All Means

Some say the PC is dead and IMHO that depends on what you mean or define a PC as. For example if you refer to a PC generically to also include servers besides workstations or other devices, then they are alive. If however your view is that PCs are only workstations and client devices, then they are on the decline.

However if your view is that a PC is defined by the underlying processor such as Intel general purpose 64 bit x86 derivative (or descendent) then they are very much alive. Just as older generations of PCs leveraging general purpose Intel based x86 (and its predecessors) processors were deployed for many uses, so to are today’s line of Xeon (among others) processors.

Even with the increase of ARM, GPU and other specialized processors, as well as ASIC and FPGAs for offloads, the role of general purpose processors continues to increase, as does the technology evolution around. Even with so called server less architectures, they still need underlying compute server platforms for running software, which also includes software defined storage, software defined networks, SDDC, SDDI, SDX, IoT among others.

Overall this is a good set of announcements by Intel and what we can also expect to be a flood of enhancements from their partners who will use the new family of Intel Xeon Scalable Processors in their products to enable software defined data infrastructures (SDDI) and SDDC.

Ok, nuff said (for now…).

Happy Earth Day 2016 Eliminating Digital and Data e-Waste

Happy Earth Day 2016 Eliminating Digital and Data e-Waste

With Earth Day 2016 on April 22, here are some thoughts about electronic waste (e-waste).

For those involved in data management or data infrastructures, the following are five tips to help cut the overhead and resulting impact of digital e-waste and later physical e-waste. Most conversations involving e-waste focus on the physical aspects from disposing of electronics along with later impacts. While physical e-waste is an important topic, lets expand the conversation including other variations of e-waste including digital. By digital e-waste I’m referring to the use of physical items that end up contributing to traditional e-waste.

digital and data ewaste

Digital e-waste ranges from the overhead of keeping extra copies of data that result in an expanding data footprint that in turn requires extra physical resources and their impact. Addressing physical e-waste also means keeping digital (not the physical items) including data waste in perspective.

Also note that digital or data waste may in fact not be waste per say if it exists as a by-product of making sure applications, data and resulting information are protected, preserved, secured and served for when needed. The warning is what can be done to make sure there are good useful effective and efficient copy data that has a relative low data footprint overhead impact, more on this later.

Here are six themes to consider to cut the impact without costing or compromising your organization when address e-waste (physical, digital, data).

1. Understand Digital e-waste

You might be familiar with the term e-waste (electronic waste), you know, those physical items that get discarded from supporting your digital lifestyle. The reason awareness around e-waste is important is because of the environmental impacts of discarding all those devices. The more known about the issue, impacts, causes and effects helps to drive awareness as well as insight into what can be done to mitigate those items.

ewaste

Devices range from smart and dumb cell phones, personal digital assistants (PDAs), tablets, notebook and workstation computers, MP3 devices, cameras, video display monitors along with larger servers, storage and networking technology, not to mention all the other Internet of Things (IoT) and Internet of Device (IoD) items. What’s important to know about physical e-waste is the impact of the various components. You can learn more about physical e-waste impact in general with a web search such as Google e-waste impact.

2. Reuse, Repurpose, Redeploy, Reconfigure, Re-Tool, Recycle

Reconfigure and retool where possible by re-driving installing newer, more energy-efficient high-capacity drives, or more performance effective devices. Besides replacing Hard Disk Drives (HDD), Solid State Devices (SSDs), magnetic tape among other mediums, look at the pro’s and con’s of replacing CPU processor sockets, upgrading memory and PCIe I/O cards for networking or storage among other enhancements.

Pro’s include being able to use the chassis longer reducing amount of physical e-waste, however at some point it can be more cost-effective to do a total replacement. However the longer you can use the asset or device the more that has as a positive benefit to cut e-waste.

Repurpose, reuse and redeploy assets such as servers, storage and networking devices in a hand me down approach assuming there is a value or benefit in doing so.

Recycle when done, dispose of the technology properly including for storage secure erase of digital media and later physical handling.

3. Responsible Recycle and Disposition of technology (including secure digital destruction)

What are you doing with, how are you disposing of physical items ranging from laptops, workstations, tablets, phones, MP3 players, TVs and monitors, servers, network and storage devices among others when no longer needed?

Are you securely erasing your digital data on HDDs as well as SSDs or even tape and optical devices before they are disposed of? If not, you should be. For example if you are not yet using or looking at Self Encrypting Drives (SED) including HDDs and SSDs for securing your data, start investigating them. Sure they have a security value proposition for when lost or stolen, however they can also cut the time to secure erase to a given standard from days or hours to minutes or seconds.

These will become e-waste

Smart shopping up front, what you want, what you need, how long can you leverage, spend more up front to get something that can last 3-5 years vs. discarding in 1.5-3 years.
Smart management with insight, know your cost and impacts, not just for PR purpose, for profit and practicality

4. Plan acquisitions with disposition in mind

Redesign and design for replacement, maximizing what you have or will acquire, using it for longer time to cut costs, improve productivity (and profitability) while reducing e-waste overhead contributing footprint.

For example, do you need or want to have the latest in new technology replacing that phone, tablet, watch or other IoT or IoD item as soon as something newer comes along? No worries if you are also doing something responsible with what was new and now old by such as donating or giving it to somebody else who might be able to get a few more years worth of use out of it before it becomes e-waste.

On the other hand, if you are acquiring technology with a 2-3 year useful life plan, what would it take to upgrade that item to a larger or more robust version using it for 3-5 years. Granted, you might not use it in its primary role for the longer duration, however can it be repurposed for some other uses? Also from a technology acquisition perspective, have a forecast and plan that can help you make smart, informed decisions up front knowing when upgrades or extra resources will be needed to prolong the usefulness of the item.

Of course you can also simply move everything to the cloud and out-source your e-waste footprint to the vendor, MSP or cloud provider.

5. Understand Changing Data Value

Keep in mind that data has either no value, some value or unknown value all of which can change over time. For example some data has value for seconds, minutes or hours and can then be discarded. Other data have some value which can be low or high which determines how as well as when, where and how to protect, preserve, secure and serve it when needed. Then there is data that has an unknown value. However, that can change over time.

Different and Changing Data Value

Over time your data may end up having no value meaning it can be discarded, or, it might have some value (low or high) meaning change how it should be protected, preserved, secured and served. Then there is data that may stay in limbo or unknown status indefinitely or until somebody, or some software or via other means decide if it has value or not.

The point is that to cut digital e-waste is to discard data with no value as soon as possible, protect, preserve, secure and serve data with value appropriately. Likewise, for all of that growing data with an unknown value, rethink how it is protected and stored, all of which has an impact on both physical as well as digital e-waste.

This means having insight and awareness into your environment, applications, data, settings, configuration and metadata, not only of the space being used, or when it was last updated. Also, look beyond when data was last modified or changed, look at when it was last read or accessed to decide how protected and secured including virus and other scans.

6. Data Footprint Reduction (DFR)

Implement data footprint reduction (DFR) to lower overhead impact not only at the target or downstream destination using compression, dedupe and other techniques. Also, move upstream to the source where the problem starts and address it there. Addressing at the source leverages various techniques from Archiving, Backup/Data Protection Modernization (rethinking what saved, when, how often, etc), Cleanup, Compression and Consolidation, Data management, Deletion and Dedupe along with storage tiering, RAID/Parity/Mirroring/Replication/Erasure Code and Advanced Parity/LRC/Forward Error Correction and other technologies.

For example if you have 10TB of data, how many copies do you have and why, how are those copies protected and what is their overhead. The issue and concern should not be primarily how many copies, rather, if those copies add or give value, then what can you do to keep them while reducing their overhead impact, besides simply trying to compress or dedupe everything. Hint, start exploring copy management as well as revisiting what you protect, when, where, why, how often along with options for implementing DFR as close to the data source as possible, as well as downstream.

Where To Learn More

What This All Means

Gain insight and awareness into what is occurring with physical and digital ewaste side stepping the greenwashing and other activity. Small steps implemented by many will have a big impact. Every bit, byte, block, blob, bucket file or object along with their copies have an impact, hopefully as well as a benefit, a question is how can you reduce the overhead while increasing your return on innovation reducing costs, complexity and overhead while enhancing organization capabilities. There are many techniques, technologies, tools and approaches to apply to various environments, after all, everything is not the same, yet there are similarities. Happy Earth Day 2016 and happy spring to those of you in the northern hemisphere (as well as elsewhere).

Ok, nuff said, for now

Green and Virtual Data Center Links

Updated 10/25/2017

Green and Virtual IT Data Center Links

Moving beyond Green Hype and Green washing

Green hype and green washing may be on the endangered species list and going away, however, green IT for servers, storage, networks, facilities as well as related software and management techniques that address energy efficiency including power and cooling along with e-waste, environmental health and safety related issues are topics that wont be going away anytime soon.

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.

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).

What this all means

The result of a green and virtual data center is that of a flexible, agile, resilient, scalable information factory that is also economical, productive, efficient, productive as well as sustainable.

SSD and Green IT moving beyond green washing

SSD and Green IT moving beyond green washing

Keeping in mind that there is no such thing as a data or information recession, not to mention that people and data are living longer, there is the need to discuss expanding data footprints. When researching his new article over on SearchSolidstateStorage.com John Hilliard reached out to ask about SSD, Green IT, energy efficiency and effectiveness trends and perspectives (you can read the article and my comments here).

In the past when Green IT and Green storage was mentioned, discussions focused around energy avoidance along with space capacity reduction. While storage efficiency and optimization in the context of space-saving and capacity consolidation are part of Green storage, so too are storage IO consolidation with SSD. For inactive or less frequently accessed data, storage optimization and efficiency can focus on using various data footprint reduction techniques including archive, backup and data protection modernization, compression, dedupe, data management and deletion, along with storage tiering and thin provisioning among others.

SSD and IO consolidation for Green IT and productivity

On the other hand, for active data where performance is important, the focus expands to how to be more effective and boosting productivity with IO consolidation using SSD and other technologies.

Note that if your data center infrastructure is not efficient, then it is possible that for every watt of energy consumed, a watt (or more) of energy is needed to cool. However if your data center cooling is effective with a resulting low or good PUE, you may not be seeing a 1:1 watt or energy used for storage to cooling ratio as was more common a few years ago.

IMHO while reducing carbon footprints is a noble and good thing, however if that is your own focus or value proposition for a solution such as SSD or other Green technologies and techniques including data footprint reduction, you are missing many opportunities.

Have a read of John’s article that includes some of my comments on energy efficiency and effectiveness to support enhanced productivity, or the other aspect of Green IT being economic enabling to avoid missed opportunities.

Green IT deferral blamed on economic recession might be result of green gap

Storage I/O Industry Trends and Perspectives

I recently saw a comment somewhere that talked about Green IT being deferred or set aside due to lack of funding because of ongoing global economic turmoil. For those who see Green IT in the context of the green washing efforts that requiring spending to gain some benefits that I can understand. After all, if your goal is to simply go and be or be seen as being green, there is a cost to doing that.

With tight or shrinking IT budgets, there are other realities and while organizations may want to do the right thing helping the environment, however that is often seen as overhead to financial conscious management.

On the other hand, turn the green washing messaging off or at least dial-it back a bit as has been the case the past couple of years.

Expand the Green IT discussion or change it around a bit from that of being seen or perceived as being green by energy efficiency or avoidance to that of effectiveness, enhanced productivity, doing more with what you have or with less and there is a different opportunity.

That opportunity is to meet the financial and business goals or requirements that as a by-product help the environment. In other words, expand the focus of Green IT to that of economics and improving on resource effectiveness and the environment gets a free ride, or, Green gets self-funded.

The Green and Virtual Data Center Book addressing optimization, effectivness, productivity and economics

The challenge is what I refer to as the Green Gap, which is the disconnect between what is talked about (e.g. messaging) and thus perceived to be Green IT and where common IT opportunities exist (or missed opportunities have occurred).

Green IT or at least the tenants of driving efficiency and effectiveness to use energy more effectively, address recycling and waste, removable of hazardous substance and other items continues to thrive. However, the green washing is subsiding and overtime organizations will not be as dismissive of Green IT in the context of improving productivity, reducing complexity and costs, optimization and related themes tied to economics where the environment gets a free ride.

SNW Fall 2011 revisited and SNIA Emerald program

A couple of weeks ago I traveled down to Orlando Florida for a few days to attend the fall 2011 SNW (Storage Networking World) produced in conjunction by IDG Computerworld and the Storage Networking Industry Association (SNIA).

SNIA and SNW

While at the Orlando event, SNIA executive director Leo Legar asked me how many SNWs I had attended and my responses was on which continent?

My answer was part in fun however also serious as I have been attending SNWs (in addition to other SNIA events) for over ten years in both North and South America as well as in Europe including presenting SNIA tutorials and SNW sessions.

SNW is always good for meeting up with old friends and acquaintances along with meeting new ones including twitter tweeps (hashtag #snwusa #snw2011 @sniacloud @snwusa) and the recent event was no exception. Granted SNW is smaller than it was during its peak in the mid 2000s however it was great to go for a couple of days of meetings, checking out the expo hall and some sessions as well as getting out and about meeting people involved with servers, storage, networking, virtualization, cloud, hardware, software and services.

SNW remains as its name implies (Storage Networking World) an event around networking as in conversations, learning, knowledge exchange, information gathering and meetings not to mention the hands on lab. I found the two days I was there adequate to get the meetings and other activities I had planned, along with time for impromptu meetings. ANother observation was that during the peak of the large mega SNW events, while there were more meetings, they were also much shorter along the lines of speed dating vs. those a couple of weeks ago where there was time to have quality conversations.

Some of the news at the recent SNW event, involved SNIA and their Green Storage Initiative (GSI) announcing the availability of the Emerald program Green IT storage energy metrics that have been in the works for several years. The SNIA Emerald program consists of specifications, taxonomies, metrics and measurements standards to gauge various types of storage power or energy usage to gauge its effectiveness. In other words, yes, Green IT and Green storage are still alive, they just are not as trendy to talk about as they were a few years ago which a shift in focus towards productivity, effective use and supporting growth to help close the green gap and missed IT as well as business opportunities.

Also during the recent SNW event, I did a book signing event sponsored by SNIA. If you have not done so, check out the SNIA Cloud Storage Initiative (CSI) who arranged for several of my new book Cloud and Virtual Data Storage Networking to be given away. Book signings are fun in that I get to meet lots of people and hear what they are doing, encountering, looking for, have done, concerned or excited about. It was handy having SNIA CSI material available at the table as I was signing books and visiting with people to be able to give them information about things such as CDMI not to mention hearing what they were doing or looking for. Note to SNIA, if we do this again, lets make sure to have someone from the CSI at the table to join in the fun and conversations as there were some good ones. Learn more about the activities of the SNIA CSI including their Cloud Data Management Initiative (CDMI) here.

SNIA Cloud Storage Initiaive CSI

Thanks again to SNIA for arranging the book signing event and for those who were not able to get a copy of my new book before they ran out, my publisher CRC Press Taylor and Francis has arranged a special SNIA and SNW discount code. To take advantage of the SNIA and SNW discount code, go to the CRC Press web site (here) and apply the discount code KVK01 during checkout for catalog item K12375 (ISBN: 9781439851739).

30 percent discount code for Cloud and Virtual Data Storage Networking Book

Thanks again to Wayne Adams (@wma01606), Leo Legar and Michael Meleedy among others who arranged for a fantastic fall 2011 SNW event along with everyone who participated in the book signing event and other conversations while in Orlando and to those who were involved virtually via twitter.

Practical Email optimization and archiving strategies

Email is a popular tool for messaging, calendaring, and managing contacts along with attachments in most organizations.

Email and messaging

Given the popularity of email and diverse ways that it is used for managing various forms of unstructured data attachments including photos, video, audio, spreadsheets, presentations and other document objects, there are corresponding back end challenges. Those back end challenges including managing the data storage repositories (e.g. file systems and storage systems) that are used for preserving and serving email documents along with enabling regulatory or compliance mandates.

Email archiving is an important enabler for regulatory compliance and e-discovery functions. However there is another important use for E-mail archiving which as a data footprint reduction (DFR) technique and technology enables storage optimization, being green and supporting growth while stretching budgets further. There is after all no such thing as a data or information recession and all one has to do to verify the trend is to look at your own email activity.

Industry Trend: Data growth and demand

There are however constraints on time, budgets and demands to do more while relying on more information and email has become a central tool for messaging including social media networking, handling of attachments and means to manage all of that data.

DFR enables more data to be stored, retained, managed and maintenance in a cost effective manner. This includes storing more data managed per person, where when the additional data being retained adds value to an organization. Also included is keeping more data readily accessible, not necessarily instantly accessible, however but within minutes instead of hours or days depending on service requirements.

Data footprint reduction (DFR) techniques and technologies

Here is a link to a recent article that I did presenting five tips and strategies for optimizing e-mail using archiving.

Hopefully many of you will find these to be common sense tips being implemented, however if not, now is the time to take action to stretch your resources further to do more.

In general email optimization tips include:

  • Set policies for retention and disposal
  • Establish filters and rules
  • Index and organize your inbox
  • Archive messages regularly
  • Perform routine cleanup and optimization
  • Leverage cloud data protection services and solutions

When it comes to archiving projects, walk before you run, establish success to build upon for broader deployment of E-mail archiving by finding and address low hanging fruit opportunities.

Instead of trying to do to much, find opportunities that can be addressed and leveraged as examples to build business cases to move forward.

By having some success stories and proof points, these can be used to help convince management to support additional steps not to mention getting them to back your polices to achieve success.

An effective way to convince management these days is to show them how by taking additional Email archiving steps you can support increased growth demand, reduce costs while enhancing productivity not to mention adding compliance and ediscovery capabilities as side benefits.

You can read more here and here, ok, nuff said for now.

Is FCoE Struggling to Gain Traction, or on a normal adoption course?

Here is an article by Drew Robb over at Enterprise Storage Forum about Fibre Channel over Ethernet (FCoE) and its state of adoption. Drews article includes comments and perspectives from myself around where FCoE is going and why it is on a long road and not a sprint for a short temporal technology play (e.g. not a quick passing fad or bandwagon trend).

If you measure FCoE adoption in months, sure, its been slow to gain adoption and deployment similar to how Ethernet, Fibre Channel (FC) and even iSCSI took time to evolve. Part of the time involved is for developing the standards, implementing the technology as well as expanding the capabilities of the new tools. Another part of the time required for technologies that are targeted to be around for a decade or more include ecosystem maturity, education not to mention customers being comfortable with along with having budget to buy the new items.

I have previously said that FCoE was in the trough of disillusionment and depending on your view, that could be either entering, exiting or there to stay. Not surprisingly some cheerleaders thought that saying FCoE was in the trough of disillusionment was being cynical, while some cynics were cheerleading.

My point around FCoE is that any technology or paradigm that goes through a hype cycle that will actually have long term legs or be around for years if not decades goes through a post initial hype disillusionment phase before reappearing. Technologies or trends that go through the trough of disillusionment that will eventually reappear sometimes go to Some Day Isle for rest and relaxation (R and R). Some Day Isle for those not familiar with it is a visional or fictional place that some day you will go to, a wishful happy place so to speak that is perfect for hyperbole R and R. After some R and R, these trends, technologies or techniques often reappear well rested and ready for the next wave of buzz, fud, hype and activity.

Certainly there have been and will continue to be more battles or matches tied to early deployments along with plenty of hype or FUD. After all, if FCoE were to simply pack up and go away like some cynics or naysayers suggest, what will they have to talk, blog, write or speak about? Similarly if FCoE magically goes mainstream tomorrow, the cheerleaders will have to find a new bandwagon or Shiny New Toy (SNT) to rally around.

Also as I have said in the past, its not if, rather when FCoE will be deployed in yours or your customers environment along with how and using what tools or technologies. Another question to pose around FCoE as a converged technology is will you use it in a true converged manner meaning adapting how server, storage and networking resources are managed including best practices? Or, will you use FCoE in a hybrid SAN or LAN mode using traditional SAN and LAN management practice and separate teams perhaps even battling over who owns the tools or technology.

Fwiw, in case you did not pick up on it from my previous posts, tips, articles and coverage in books, I think that FCoE has a very bright future as does NAS and iSCSI along with shared SAS as complimentary technologies when used for the applicable scenario.

What is your take, Is FCoE struggling to gain traction?

Is FCoE on a normal technology evolution path and timeline?

Is it too early to tell what the future holds for FCoE?

Is FCoE too little to late and if so why?

Ok, nuff said for now.

As the Hard Disk Drive HDD continues to spin

As the Hard Disk Drive HDD continues to spin

server storage data infrastructure i/o iop hdd ssd trends

Updated 2/10/2018

Despite having been repeatedly declared dead at the hands of some new emerging technology over the past several decades, the Hard Disk Drive (HDD) continues to spin and evolve as it moves towards its 60th birthday.

More recently HDDs have been declared dead due to flash SSD that according to some predictions, should have caused the HDD to be extinct by now.

Meanwhile, having not yet died in addition to having qualified for its AARP membership a few years ago, the HDD continues to evolve in capacity, smaller form factor, performance, reliability, density along with cost improvements.

Back in 2006 I did an article titled Happy 50th, hard drive, but will you make it to 60?

IMHO it is safe to say that the HDD will be around for at least a few more years if not another decade (or more).

This is not to say that the HDD has outlived its usefulness or that there are not other tiered storage mediums to do specific jobs or tasks better (there are).

Instead, the HDD continues to evolve and is complimented by flash SSD in a way that HDDs are complimenting magnetic tape (another declared dead technology) each finding new roles to support more data being stored for longer periods of time.

After all, there is no such thing as a data or information recession!

What the importance of this is about technology tiering and resource alignment, matching the applicable technology to the task at hand.

Technology tiering (Servers, storage, networking, snow removal) is about aligning the applicable resource that is best suited to a particular need in a cost as well as productive manner. The HDD remains a viable tiered storage medium that continues to evolve while taking on new roles coexisting with SSD and tape along with cloud resources. These and other technologies have their place which ideally is finding or expanding into new markets instead of simply trying to cannibalize each other for market share.

Here is a link to a good story by Lucas Mearian on the history or evolution of the hard disk drive (HDD) including how a 1TB device that costs about $60 today would have cost about a trillion dollars back in the 1950s. FWIW, IMHO the 1 trillion dollars is low and should be more around 2 to 5 trillion for the one TByte if you apply common costs for management, people, care and feeding, power, cooling, backup, BC, DR and other functions.

Where To Learn More

View additional NAS, NVMe, SSD, NVM, SCM, Data Infrastructure and HDD related topics via the following links.

Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

Software Defined Data Infrastructure Essentials Book SDDC

What This All Means

IMHO, it is safe to say that the HDD is here to stay for at least a few more years (if not decades) or at least until someone decides to try a new creative marketing approach by declaring it dead (again).

Ok, nuff said, for now.

Have VTLs or VxLs become Zombies, Declared dead yet still alive?

Have you heard or read the reports and speculation that VTLs (Virtual Tape Libraries) are dead?

It seems that in IT the all to popular trend is to declare something dead so that your new product or technology can have a chance of making it in to the market or perhaps seen in a better light.

Sometimes this approach works to temporary freeze the market until common sense and clarity returns to the market or until something else fun to talk about comes along and in other cases, the messages can fall on deft ears.

The approach of declaring something dead tends to play well for those who like shiny new toys (SNT) or new shiny toys (NST) and being on the popular, cool trendy bandwagon.

Not surprisingly, while some actual IT customers can fall into the SNT or NST syndrome, its often the broader industry including media, bloggers, analysts, consultants and other self proclaimed or anointed pundits as well as vendors who latch on to the declare it dead movement. After all, who wants to talk about something that is old, boring and already being sold to paying customers who are using it. Now this is not a bad thing as we need a balance of up and coming challengers to keep the status quo challenged, likewise we need a balance of the new to avoid death grips on the old and what is working.

Likewise, many IT customers particularly larger ones tend to be very risk averse and conservative with their budgets protecting their investments thus they may only go leading bleeding edge if there is a dual redundant blood bank with a backup on hot standby (thats some HA humor BTW).

Another reason that declaring items dead in support of SNT and NST is that while many of the commonly declared dead items are on the proverbial plateau of productivity for IT customers, that also can mean that they are on the plateau of profitability for the vendors.

However, not all good things last and at sometime, there is the need to transition from the old to the new and this is where things like virtualization including virtual tape libraries or virtual disk libraries or virtual storage library or what ever you want to call a VxL (more on what a VxL is in a moment) can come into play.

I realize that for some, particularly those who like to grasp on to SNT, NST and ride the dead pool bandwagons this will probably appear as snarky or cynical which is fine, after all, for some, you should be laughing to the bank and if not, you may in fact be missing out on an opportunity for playing in the dead pool marketing game.

Now back to VxL.

In the case of VTLs, for some it is the T word that bothers them, you know T as in Tape which is not a SNT or NST in an age where SSD has supposedly killed the disk drive which allegedly terminated tape (yeah right). Sure tape is not being used as much for backup as it has in the past with its role shifting to that of longer term retention, something that it is well suited for.

For tape fans (or cynics) you can read more here, here and here. However there is still a large amount of backup/restore along with other data protection or preservation (e.g. archiving) processing (software tools, processes, procedures, skill sets, management tools) that still expects to see tape.

Hence this is where VTLs or VxLs come into play leveraging virtualization in an Life Beyond Consolidation (and here) scenario providing abstraction, transparency, agility and emulation and IMHO are still very much alive and evolving.

Ok, for those who do not like or believe in or of its continued existence and evolving role, substitute the T (tape) with X and you get a VxL. That is, plug in what ever X word that makes you happy or marketable or a Shiny New TLA. For example Virtual Disk Library, Virtual Storage Library, Virtual Backup Library, Virtual Compression Library, Virtual Dedupe Library, Virtual ILM Library, Virtual Archive Library, Virtual Cloud Library and so forth. Granted some VxLs only emulate tape and hence are VTLs while others support NAS and other protocols (or personalities) not to mention functionality ranging from replication, DFR as well as automated policy management.

However, keep in mind that if your preference is VTL, VxL or what ever other buzzword bingo name that you want to use or come up with, look at how virtualization in the form of abstraction, transparency and emulation can bridge the gap between the new (disk based data protection) combined with DFR (Data Footprint Reduction) and the old (existing backup/restore, archive or other management tools and processes.

Here are some additional links pertaining to VTLs (excuse me, VxLs):

  • Not to mention here, here, here, here or here.
