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.

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.

Happy Earth Day 2010!

Here in the northern hemisphere it is late April and thus mid spring time.

That means the trees sprouting their buds, leaves and flowering while other plants and things come to life.

In Minnesota where I live, there is not a cloud in the sky today, the sun is out and its going to be another warm day in the 60s, a nice day to not be flying or traveling and thus enjoy the fine weather.

Among other things of note on this earth day 2010 include:

  • Minnesota Twins new home Target Field was just named the most Green Major League Baseball (MLB) stadium as well as greenest in the US with its LEED (or see here) certification.
  • Icelands Eyjafjallajokull volcano continues to spew water vapor steam, CO2 and ash at a slower rate than last week when it first erupted with some speculating that there could be impending activity from other Icelandic volcanos. Some estimates placed the initial eruption CO2 impact and subsequent flight cancellations to be neutral, essentially canceling each other out, however Im sure we will be hearing many different stories in the weeks to come.

  • Image of Iceland Eyjafjallajokull Volcano Eruption via Boston.com

  • Flights to/from and within Europe and the UK are returning to normal
  • Toyota continues to deal with recalls on some of their US built automobiles including the energy efficient Prius, some of which may have been purchased during the recent US cash for clunkers (CFC) program (hmm, is that ironic or what?)
  • Greenpeace in addition to using a Facebook page to protest Facebook data center practices is now targeting cloud IT in general including just before the Apple iPad launch (Heres some comments from Microsoft).
  • Vendors in all industries are lining up for the second coming of Green marketing or perhaps Green Washing 2.0

The new Green IT, moving beyond Green wash and hype

Speaking of Green IT including Green Computing, Green Storage, Virtualization, Cloud, Federation and more, here is a link to a post that I did back in February discussing how the Green Gap continues to exist.

The green gap exists and centers around the confusion of what Green means along with the common disconnects between core IT issues or barriers to becoming more efficient, effective, flexible and optimized from both an economic as well as environmental basis to those commonly messaged to under the green umbrella (read more here).

Regardless of where you stand on Green, Green washing, Green hype, environmentalism, eco-tech and other related themes, for at least a moment, set aside the politics and science debates and think in terms of practicality and economics.

That is, look for simple, recurring things that can be done to stretch your dollar or spending ability in order to support demand (See figure below) in a more effective manner along with reducing waste. For example to meet growing demand requirements in the face of shrinking or stagnate budgets, the action is to stretch available resources to do more work when needed, or retain more where applicable with the same or less footprint. What this means is that while common messaging is around reducing costs, look at the inverse which is to do more with available budgets or resources. The result is green in terms of economic and environmental benefits.

IT Resource demand
Increasing IT Resource Demand

Green IT wheel of oppourtunity
Green IT enablement techniques and technologies

Look at and understand the broader aspects of being green which has both economical and environmental benefits without compromising on productivity or functionality. There are many aspects or facets of being green beyond those commonly discussed or perceived to be so (See Green IT enablement techniques and technologies figure above).

Certainly recycling of paper, water, aluminum, plastics and other items including technology equipment are important to reduce waste and are things to consider. Another aspect of reducing waste particularly in IT is to avoid rework that can range from finding network bottlenecks or problems that result in continuous retransmission of data for failed backup, replication or data transfers that cause lost opportunity or resource consumption. Likewise programming errors (bugs) or miss configuration that results in rework or lost productivity also are forms of waste among others.

Another theme is that of shifting from energy avoidance to energy efficiency and effectiveness which are often thought to the same. However the expanded focus is also about getting more work done when needed with the same or less resources (See figure below) for example increasing activity (IOPS, transactions, emails or video served, bandwidth or messages) per watt of energy consumed.

From energy avoidence to effectiveness
Shifting from energy avoidance to effectiveness

One of the many techniques and approaches for addressing energy including stretching resources and being green include intelligent power management (IPM). With IPM, the focus is not strictly centered around energy avoidance, instead about inteligently adapting to different workloads or activity balancing performance and energy. Thus when there is work to be done, get the work done quickly with as little energy as possible (IOP or activity per watt), when there is less work, provide lower performance and thus smaller energy requirements, or when no work to be done, going into additional energy saving modes. Thus power management does not have to be exclusively about turrning off the lights or IT equipment in order to be green.

The following two figures look at Green IT past, present and future with an expanding focus around optimization and effectiveness meaning getting more work done, storing more data for longer periods of time, meeting growth demands with what appears to be additional resources however at a lower per unit cost without compromising on performance, availability or economics.

Green IT wheel of oppourtunity
Green IT: Past, present and future shift from avoidance to efficiency and effectiveness

Green IT wheel of oppourtunity
The new Green IT: Boosting business effectiveness, maximize ROI while helping the environment

If you think about going green as simply doing or using things more effectively, reducing waste, working more intelligently or effectively the benefits are both economical and environmentally positive (See the two figures above).

Instead of finding ways to fund green initiatives, shift the focus to how you can enable enhanced productivity, stretching resources further, doing more in the same or smaller footprint (floor space, power, cooling, energy, personal, licensing, budgets) for business economic and environmental sustainability with the result being environmental encampments.

Also keep in mind that small percentage changes on a large or recurring basis have significant benefits. For example a small change in cooling temperatures while staying within vendor guideline recommendations can result in big savings for large environments.

 

Bottom line

If you are a business and discounting green as simply a fad, or perhaps as a public relations (PR) initiative or activity tied to reducing carbon footprints and recycling then you are missing out on economic (top and bottom line) enhancement opportunities.

Likewise if you think that going green is only about the environment, then there is a missed opportunity to boost economic opportunities to help fund those inititiaves.

Going green means many different things to various people and is often more broad and common sense based than most realize.

That is all for now, happy earth day 2010

The other Green Storage: Efficiency and Optimization

Some believe that green storage is specifically designed to reduce power and cooling costs.

The reality is that there are many ways to reduce environmental impact while enhancing the economics of data storage besides simply booting utilizing.

These include optimizing data storage capacity as well as boosting performance to increase productivity per watt of energy used when work needs to be done.

Some approaches require new hardware or software while others can be accomplished with changes to management including reconfiguration leveraging insight and awareness of resource needs.

Storage Efficiency and Optimization – The Other Green

For those of you in the New York City area, I will be presenting live in person at Storage Decisions September 23, 2009 conference The Other Green, Storage Efficiency and Optimization.

Throw out the "green“: buzzword, and you’re still left with the task of saving or maximizing use of space, power, and cooling while stretching available IT dollars to support growth and business sustainability. For some environments the solution may be consolation while others need to maintain quality of service response time, performance and availability necessitating faster, energy efficient technologies to achieve optimization objectives.

To accomplish these and other related issues, you can turn to the cloud, virtualization, intelligent power management, data footprint reduction and data management not to mention various types of tiered storage and performance optimization techniques. The session will look at various techniques and strategies to optimize either on-line active or primary as well as near-line or secondary storage environment during tough economic times, as well as to position for future growth, after all, there is no such thing as a data recession!

Topics, technologies and techniques that will be discussed include among others:

  • Energy efficiency (strategic) vs. energy avoidance (tactical), whats different between them
  • Optimization and the need for speed vs. the need for capacity, finding the right balance
  • Metrics & measurements for management insight, what the industry is doing (or not doing)
  • Tiered storage and tiered access including SSD, FC, SAS, tape, clouds and more
  • Data footprint reduction (archive, compress, dedupe) and thin provision among others
  • Best practices, financial incentives and what you can do today

This is a free event for IT professionals, however space I hear is limited, learn more and register here.

For those interested in broader IT data center and infrastructure optimization, check out the on-going seminar series The Infrastructure Optimization and Planning Best Practices (V2.009) – Doing more with less without sacrificing storage, system or network capabilities Seminar series continues September 22, 2009 with a stop in Chicago. This is also a free Seminar, register and learn more here or here.

SPC and Storage Benchmarking Games

Storage I/O trends

There is a post over in one of the LinkedIn Discussion forums about storage performance council (SPC) benchmarks being miss-leading that I just did a short response post to. Here’s the full post as LinkedIn has a short post response limit.

While the SPC is far from perfect, it is at least for block, arguably better than doing nothing.

For the most part, SPC has become a de facto standard for at least block storage benchmarks independent of using IOmeter or other tools or vendor specific simulations, similar how MSFT ESRP is for exchange, TPC for database, SPEC for NFS and so forth. In fact, SPC even recently rather quietly rolled out a new set of what could be considered the basis for Green storage benchmarks. I would argue that SPC results in themselves are not misleading, particularly if you take the time to look at both the executive and full disclosures and look beyond the summary.

Some vendors have taken advantage of the SPC results playing games with discounting on prices (something that’s allowed under SPC rules) to show and make apples to oranges comparisons on cost per IOP or other ploys. This proactive is nothing new to the IT industry or other industries for that matter, hence benchmark games.

Where the misleading SPC issue can come into play is for those who simply look at what a vendor is claiming and not looking at the rest of the story, or taking the time to look at the results and making apples to apples, instead of believing the apples to oranges comparison. After all, the results are there for a reason. That reason is for those really interested to dig in and sift through the material, granted not everyone wants to do that.

For example, some vendors can show a highly discounted list price to get a better IOP per cost on an apple to oranges basis, however, when processes are normalized, the results can be quite different. However here’s the real gem for those who dig into the SPC results, including looking at the configurations and that is that latency under workload is also reported.

The reason that latency is a gem is that generally speaking, latency does not lie.

What this means is that if vendor A doubles the amount of cache, doubles the number of controllers, doubles the number of disk drives, plays games with actual storage utilization (ASU), utilizes fast interfaces from 10 GbE  iSCSI to 8Gb FC or FCoE or SAS to get a better cost per IOP number with discounting, look at the latency numbers. There have been some recent examples of this where vendor A has a better cost per IOP while achieving a higher number of IOPS at a lower cost compared to vendor B, which is what is typically reported in a press release or news story. (See a blog entry that also points to a CMG presentation discussion around this topic here.

Then go and look at the two results, vendor B may be at list price while vendor A is severely discounted which is not a bad thing, as that is then the starting list price as to which customers should start negotiations. However to be fair, normalize the pricing for fun, look at how much more equipment vendor A may need while having to discount to get the price to offset the increased amount of hardware, then look at latency.

In some of the recent record reported results, the latency results are actually better for a vendor B than for a vendor A and why does latency matter? Beyond showing what a controller can actually do in terms of levering  the number of disks, cache, interface ports and so forth, the big kicker is for those talking about SSD (RAM or FLASH) in that SSD generally is about latency. To fully effectively utilize SSD which is a low latency device, you would want a controller that can do a decent job at handling IOPS; however you also need a controller that can do a decent job of handling IOPS with low latency under heavy workload conditions.

Thus the SPC again while far from perfect, at least for a thumb nail sketch and comparison is not necessarily misleading, more often than not it’s how the results are utilized that is misleading. Now in the quest for the SPC administrators to try and gain more members and broader industry participation and thus secure their own future, is the SPC organization or administration opening itself up to being used more and more as a marketing tool in ways that potentially compromise all the credibility (I know, some will dispute the validity of SPC, however that’s reserved for a different discussion ;) )?

There is a bit of Déjà here for those involved with RAID and storage who recall how the RAID Advisory Board (RAB) in its quest to gain broader industry adoption and support succumbed to marketing pressures and use or what some would describe as miss-use and is now a member of the “Where are they now” club!

Don’t get me wrong here; I like the SPC tests/results/format, there is a lot of good information in the SPC. The various vendor folks who work very hard behind the scenes to make the SPC actually work and continue to evolve it also all deserve a great big kudos, an “atta boy” or “atta girl” for the fine work that have been doing, work that I hope does not become lost in the quest to gain market adoption for the SPC.

Ok, so then this should all then beg the question of what is the best benchmark. Simple, the one that most closely resembles your actual applications, workload, conditions, configuration and environment.

Ok, nuff said.

U.S. EPA Looking for Industry Input on Energy Star for Storage

Following up on previous blog posts, here is some information that the U.S. EPA is looking for comments from industry on an Energy Start for enterprise storage program following on the heels of the Energy Star for Server program.

US EPA Energy Star LogoUS EPA Energy Star wants and needs you!
U.S. EPA Energy Star Wants and Needs You!

Here’s the message received from the EPA via their mailing list this past week (in italics below):

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

Please see the attached letter from the U.S. Environmental Protection Agency (EPA) announcing their intent to pursue development of an ENERGY STAR specification for Enterprise Storage equipment.  If you have any questions or concerns, please contact Andrew Fanara, EPA, at fanara.andrew@epa.gov or Stephen Pantano, ICF International, at spantano@icfi.com.

Thank you for your support of ENERGY STAR.

Here’s the intro letter excerpted from the above email notification (in italics below):

April 23, 2009

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

This letter is intended to inform all stakeholders that the U.S. Environmental Protection Agency (EPA) intends to continue its efforts towards the development of an ENERGY STAR® specification for enterprise data storage equipment. Following is an outline of EPA’s general goals and next steps.


ENERGY STAR is a voluntary partnership between government, businesses, and purchasers designed to encourage the manufacture, purchase, and use of efficient products to help protect the environment. Products that earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict energy efficiency guidelines. Manufacturers that qualify their products to meet ENERGY STAR requirements may use the label as a tool to educate their customers about the enhanced value of these products.

To date:
•More than 2,000 manufacturers are partnering with ENERGY STAR,
•More than 40,000 product models carry the ENERGY STAR label across more than 50 product categories,
•More than 70% of Americans recognize the ENERGY STAR label,
•Consumers have purchased more than 2.5 billion ENERGY STAR qualified products, and
•Americans, with the help of ENERGY STAR, saved enough energy in 2008 to avoid greenhouse gas emissions equivalent to those from 29 million cars — while saving $19 billion on utility bills.

In the last several years, the energy saving opportunities in data centers have been well documented. However, barriers to energy efficiency still persist and need to be addressed. EPA is pursuing a dual strategy to overcome these challenges by helping purchasers more easily identify energy efficient IT equipment with the use of the ENERGY STAR designation, and by encouraging organizations to benchmark the energy performance of their data centers.


In pursuit of this strategy, EPA will introduce an ENERGY STAR Computer Server specification in the coming weeks. In addition, EPA recently conducted a scoping effort to evaluate enterprise storage products for inclusion in the ENERGY STAR program. EPA reviewed available market research and facilitated discussions with product manufacturers, industry associations, and other interested parties. EPA concluded that IT purchasers would benefit from access to standardized information about the energy performance of storage equipment made available through the ENERGY STAR program. As a result, EPA intends to begin the specification development process. Details on this process will be forthcoming in the next several weeks.

To be added to the enterprise storage e-mail distribution list, please send your full contact information to Stephen Pantano at spantano@icfi.com. To stay informed about the ENERGY STAR specification development process for computer servers and other EPA data center initiatives please visit: www.energystar.gov/datacenters.


Thank you for your continued support of ENERGY STAR and please direct additional questions to Andrew Fanara at fanara.andrew@epa.gov or Stephen Pantano of ICF International, at spantano@icfi.com.

Sincerely,

Andrew Fanara
U.S. Environmental Protection Agency, Climate Protection Partnerships Division ENERGY STAR Program Manager

My take on the Energy Star programs is that as long as they add value including reflecting how energy is effectively used both when IT equipment such as servers and storage are in use, as well as in energy saving or avoidance modes are reflected, they can and should be a good thing.

However industry will need to work together across different trade and focus groups as well as factor in how supporting metrics will be applicable and reflective thus accepted by IT data center environments. This means metrics and measurements for both active or working while in use energy efficiency modes such as IOPS, bandwidth, messages or transactions, files or videos per watt of energy, as well as metrics for in-active or dormant data such as capacity per watt per usable footprint. Check out Chapter 5 (Measurements and Metrics) in "The Green and Virtual Data Center" (CRC) to learn more.

Various industry trade and focus groups including Storage Performance Council (SPC), SNIA GSI, Green Grid, SPEC and others are working on various metrics and aligning themselves to work with EPA. If you are in an IT data center involved with servers or storage, consider getting involved with one or more of these groups to help influence and shape what these programs will look like or affect your organization in the future.

Ok, nuff said.

Storage Optimization: Performance, Availability, Capacity, Effectiveness

Storage I/O trends

With the IT and storage industry shying away from green hype, green washing and other green noise, there is also a growing realization that the new green is about effectively boosting efficiency to improve productivity and profitability or to sustain business and IT growth during tough economic times.

This past week while doing some presentations (I’ll post a link soon to the downloads) at the 2008 San Francisco installment of Storage Decisions event focused on storage professionals, as well as a keynote talk at the value added reseller (VAR) channel professional focused storage strategies event, a common theme was boosting productivity, improving on efficiency, stretching budgets and enabling existing personal and resources to do more with the same or less.

During these and other presentations, keynotes, sessions and seminars both here in the U.S. as well as in Europe recently, these common themes of booting efficiency as well as the closing of the green gap, that is, the gap between industry and marketing rhetoric around green hype, green noise, green washing and issues that either do not resonate with, or, can not be funded by IT organizations compared with the disconnect of where many IT organizations issues exist which are around power, cooling, floor space or footprint as well as EH&S (Environmental health and safety) and economics.

The green gap (here, and here, and here) is that many IT organizations around the world have not realized due to green hype around carbon footprints and related themes that in fact, boosting energy efficiency for active and on-line applications, data and workloads (e.g. doing more I/O operations per second-IOPS, transactions, files or messages processed per watt of energy) to address power, cooling, floor space are in fact a form of addressing green issues, both economic and environmental.

Likewise for inactive or idle data, there is a bit more of a linkage that green can mean powering things off, however there is also a disconnect in that many perceive that green storage for example is only green if the storage can be powered off which while true for in-active or idle data and applications, is not true for all data and applications types.

As mentioned already, for active workloads, green means doing more with the same or less power, cooling and floor space impact, this means doing more work per unit of energy. In that theme, for active workload, a slow, large capacity disk may in fact not be energy efficient if it impedes productivity and results in more energy to get the same amount of work done. For example, larger capacity SATA disk drives are also positioned as being the most green or energy efficiency which can be true for idle or in-active or non performance (time) sensitive applications where more data is stored in a denser footprint.

However for active workload, lower capacity 15.5K RPM 300GB and 400GB Fibre Channel (FC) and SAS disk drives that deliver more IOPS or bandwidth per watt of energy can get more work done in the same amount of time.

There is also a perception that FC and SAS disk drives use more power than SATA disk drives which in some cases can be true, however current generations of high performance 10K RPM and 15.5K RPM drives have very similar power draw on a raw spindle or device basis. What differs is the amount of capacity per watt for idle or inactive applications, or, the number of IOPS or amount of performance for active configurations.

On the other hand, while not normally perceived as being green compared to tape or IPM and MAID (1st generation and MAID 2.0) solutions, along with SSD (Flash and RAM), not to mention fast SAS and FC disks or tiered storage systems that can do more IOPS or bandwidth per watt of energy are in fact green and energy efficiency for getting work done. Thus, there are two sides to optimizing storage for energy efficiency, optimizing for when doing work e.g. more miles per gallon per amount of work done, and, how little energy used when not doing work.

Thus, a new form of being green to sustain business growth while boosting productivity is Gaining Realistic Economic Efficiency Now that as a by product helps both business bottom lines as well as the environment by doing more with less. These are themes that are addressed in my new book

“The Green and Virtual Data Center” (Auerbach) that will be formerly launched and released for generally availability just after the 1st of the year (hopefully sooner), however you can beat the rush and order your copy now to beat the rush at Amazon and other fine venues around the world.

Ok, nuff said.

Green Storage – Practical Ways to Reduce Power Consumption

Storage I/O trends

The busy 2008 fall events activities continue, last week was New Orleans at Arnauds and Chicago at Morton’s where the topic was BC/DR in and for virtualized environments in a series of dinner seminar events with IT professionals. This coming week it’s off to New York City and then Ceder Rapids Iowa. In New York City, I will be there to present at Storage Decisions on several topics including Green Storage – Practical Ways to Reduce Power Consumption on Tuesday, Clustered Storage – From SMB, to Scientific, to Social Networking and Web 2.0 on Wednesday morning. For those attending Storage Decisions in New York, stop by and say hello as I will also be in the expo hall during the ask the experts (ATE) sessions on Tuesday late afternoon. For those not attending, Storage Decisions usually posts a link to the slides shortly after the event as well as watch for several new pod casts, videos, tips and related content to appear soon, some of which will be produced next week while Im in New York City.

Also next week while in New York City, on Monday evening I will be the key-note speaker for the Storage Strategies for channel professionals event also at the New York Hilton.

Ok, nuff said.

Spring 2008 Storage Descisions Wrap-Up

Once again the Techtarget (TT) folks put on a great event at the spring 2008 edition of Storage Decisions (SD) event in Chicago, tip of the hat to the whole TT crew. SD is known as an IT consumer/user event as opposed to industry events like SNW that are known as a vendor to vendor networking event. TT has added a new form over the past year that occurs the day/night before SD focused on the channel and var audiences with a dinner networking seminar called StorageStrategies. While SD continues to be focused on the IT consumer aka user, the TT channel program is a means for vendors to get in front of perspective channel partners to tell their story and value proposition of why they should be partnered. It?s a fun and growing event that I have been involved with for over a year now talking with the channel folks about issues and opportunities to address the various needs IT organizations. If you are a vendor looking to expand your channel presence, or, a channel partner var looking for new solutions, technologies and partners, these series are a great way of networking.

The main focus however last week was the SD event which had a great turnout of around 550 IT and storage professionals (not counting vendors, exhibitors, vars, media and analysts). To put the attendance in perspective compared to other events. I guess you could virtualizes the attendance of IT folks at about 65,431 however the reality number quoted by TT and observed (during the sessions, lunch and so forth) was in the mid 500?s (not including vendors, exhibitors, vars, media, analysts, hotel personal, stumping politicians, high school marching bands, tour groups and the homeless). Talking with vendors and exhibitors, the census was that they were either getting a boat load of good leads, or, getting actual appointments and meetings for near term opportunities that might help their sales reps win or buy a new boat, car, home, or cup of coffee.

Having been both a customer and a vendor before becoming an analyst years ago, it?s fun to walk the exhibit area listening and watching the different approaches and pitches by the booth personal. Some are focused on just getting leads, some on showing you?re their demo, some on how well they memorized their buzzword laden sales pitch, some can even give you their elevator value prop pitch in less than 30 seconds to get you to stay for another five minutes prompting a rescheduling to give them another 20 minutes of time. I?m still waiting for some vendor to bring in the carnival midway skills game where participants use a water gun or other item to know that particular vendors competitors logo on a target down, or, to knock down various IT issues.

In between all my meetings, presentations, recording some new video techtalks (Data footprint reduction, hot topics for the channel, clustered storage and NAS for SMBs) and other activity at the recent Storage Decisions event in Chicago this past week, I was able to meet up with some friends and former co-workers for a relaxing dinner at Buddy Guy?s Legends across the street from the event hotel. Performing on stage was Vino Louden who plays the guitar with the sole and feeling of Stevie Ray Vaughn and creative flare of Jimmy Page backed by his three man band. If you have never been to Legends you still have time to go there as the joint is staying open until their new facility is ready.

As soon as TechTarget posts the links to the session presentations including my talks on ?Clustered Storage and NAS? that included Web 2.0 and bulk storage as well as my talk about ?Green and Energy Efficient Storage? I will post them on this blog.

The Many Faces of Solid State Devices/Disks (SSD)

Storage I/O trends

Here’s a link to a recent article I wrote for Enterprise Storage Forum titled “Not a Flash in the PAN” providing a synopsis of the many faces, implementations and forms of SSD based technologies that includes several links to other related content.

A popular topic over the past year or so has been SSD with FLASH based storage for laptops, also sometimes referred to as hybrid disk drives along with announcements late last year by companies such as Texas Memory Systems (TMS) of a FLASH based storage system combining DRAM for high speed cache in their RAMSAN-500 and more recently EMC adding support for FLASH based SSD devices in their DMX4 systems as a tier-0 to co-exist with other tier-1 (fast FC) and tier-2 (SATA) drives.

Solid State Disks/Devices (SSD) or memory based storage mediums have been around for decades, they continue to evolve using different types of memory ranging from volatile dynamic random access (DRAM) memory to persistent or non-volatile RAM (NVRAM) and various derivatives of NAND FLASH among other users. Likewise, the capacity cost points, performance, reliability, packaging, interfaces and power consumption all continue to improve.

SSD in general, is a technology that has been miss-understood over the decades particularly when simply compared on a cost per capacity (e.g. dollar per GByte) basis which is an unfair comparison. The more approaches comparison is to look at how much work or amount of activity for example transactions per second, NFS operations per second, IOPS or email messages that can be processed in a given amount of time and then comparing the amount of power and number of devices to achieve a desired level of performance. Granted SSD and in particular DRAM based systems cost more on a GByte or TByte basis than magnetic hard disk drives however it also requires more HDDs and controllers to achieve the same level of performance not to mention requiring more power and cooling than compared to a typical SSD based device.

The many faces of SSD range from low cost consumer grade products based on consumer FLASH products to high performance DRAM based caches and devices for enterprise storage applications. Over the past year or so, SSD have re-emerged for those who are familiar with the technology, and emerged or appeared for those new to the various implementations and technologies leading to another up swinging in the historic up and down cycles of SSD adoption and technology evolution in the industry.

This time around, a few things are different and I believe that SSD in general, that is, the many difference faces of SSD will have staying power and not fade away into the shadows only to re-emerge a few years later as has been the case in the past.

The reason I have this opinion is based on two basic premises which are economics and ecological”. Given the focus on reducing or containing costs, doing more with what you have and environmental or ecological awareness in the race to green the data center and green storage, improving on the economics with more energy efficiency storage, that is, enabling your storage to do more work with less energy as opposed to avoiding energy consumption, has the by product of improved economics (cost savings and improved resource utilization and better service delivery) along with ecological (better use of energy or less use of energy).

Current implementations of SSD based solutions are addressing both the energy efficiency topics to enable better energy efficiency ranging from maximizing battery life to boosting performance while drawing less power. Consequently we are now seeing SSD in general are not only being used for boosting performance, also we are seeing it as one of many different tools to address power, cooling, floor space and environmental or green storage issues.

Here’s a link to a StorageIO industry trends and perspectives white paper at www.storageio.com/xreports.htm.

Here’s the bottom line, there are many faces to SSD. SSD (FLASH or DRAM) based solutions and devices have a place in a tiered storage environment as a Tier-0 or as an alternative in some laptop or other servers where appropriate. SSD compliments other technologies and SSD benefits from being paired with other technologies including high performance storage for tier-1 and near-line or tier-2 storage implementing intelligent power management (IPM).
