What have I been doing this winter?

Its been almost a month since my last post and want to say hello and let you know what I have been doing.

What I have been doing is:

  • Accumulating a long list of ideas for upcoming blog post, article, tips, webinars and other content.
  • Recording some podcasts, web casts doing interviews and commentary along with a few articles here and there.
  • Working with some new venues where if all comes together you should be seeing material or commentary appearing soon.
  • Filling some dates for the 2011 out and about events and activities page.
  • Doing research in several different areas as well as working with clients on various project activities, many of which that are NDA.
  • Getting some recently finished content ready to appear on the main web site as well as in the blog and other venues.
  • Attending vendor events and briefing sessions on solutions some of which are yet to be announced.
  • Enjoying the cold and snowy winter as best as can be (see some videos here) while trying to avoid cold and flue season.

In addition to the above, I have been trying to stay very focused on is getting my new book which is titled Cloud and Virtual Data Storage Networking (CRC) wrapped up for a summer 2011 release. This is my third solo book project that is in addition to co writing or contributing to several other book projects.

Cloud and Virtual Data Storage Networking

Im doing the project the old fashioned way which means writing it myself as opposed to using ghost writers along with a traditional publishing house (CRC, same as my last book) all of which takes a bit more time. For anyone who has done a project like this you know what is involved. For those who have not it includes research, writing, editing, working with editors and copyeditors, subject matter experts doing initial reviews, illustrations and page layouts, markups, more edits and proofs. Then there are the general project management activities along with marketing and rollout plans, companion presentation material working with the publisher and others.

Anyway, hope you are all doing well, look forward to sharing more with you soon, now it is time to get back to work…

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.

Ok, nuff said.

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

March Metrics and Measuring Social Media

What metrics matter for social media and networking?

Of course the answer should be it depends.

     

For example, would that be number of followers or how many posts, tweets or videos you post?

How about the number of page hits, pages read or unique visitors to a site, perhaps time on site?

Or, how about the number of times a visitor returns to a site or shares the link or information with others?

What about click through rates, page impressions, revenue per page and related metrics?

Maybe the metric is your blog ranking or number of points on your favorite community site such as Storage Monkeys or Wikibon among others?

Another metrics could be number of comments received particularly if your venue is more interactive for debate or discussion purposes compared to a site with many viewers who prefer to read (lurk). Almost forgot number of LinkedIn contacts or face book friends along with you tube and other videos or pod casts as well as who is on your blog roll.

Lets not forget how many are following or those being followed along with RSS subscribers as metrics.

To say that there are many different metrics along with reasons or interests around them would be an understatement to say the least.

Why do metrics matter in social networking?

One reason metrics are used (even by those who do not admit it) is to compare status amongst peers or others in your sphere of influence or in adjacent areas.

Who Are You and Your Influences
Some spheres of influence and influences

In additional metrics also matter for those looking to land or obtain advertising sponsors for their sites or perhaps to help gain exposure if looking for a new job or career move. Metrics also matter to gauge the effectiveness or return on investment with social media that could range from how many followers to how far your brands reach extends into other realms and venues.

In the case of twitter, for some the key metric is number of followers (e.g. popularity) or those being followed with other metrics being number of posts or tweets along with re tweets and list inclusions.For blogs and web sites, incoming links along with site activity among other metrics factor into various ranking sites. Web site activity can be measured in several ways including total hits or visits, pages read and unique visitors among others.

Having been involved with social media from a blogging along with twitter perspective for a couple of years not to mention being a former server and storage capacity planner I find metrics to be interesting. In addition to the metrics themselves, what is also interesting is how they are used differently for various purposes including gauging cause and effect or return on social networking investment.

Regardless of your motives or objectives with metrics, here is a quick synopsis of some tools and sites that I have come across that you may already be using, or if not, that you might be interested in.

What are some metrics?

If you are interested in your twitter effectiveness, see your report card at tweet grade. Another twitter site that provides a twitter grade based on numerous factors is Twitter Grader while Klout.com characterizes your activity on four different planes similar to a Gartner Magic quadrant. Over at the customer collective they have an example of a more thorough gauge of effectiveness looking at several different metrics some of which are covered here.

Sample metricsSample Metrics

Customer Collective Metrics and Rankings

Similar to Technorati, Tekrati, or other directory and index sites, Wefollow is a popular venue for tracking twitter tweeps based on various has tags for example IT or storage among many others. Tweet level provides a composite ranking determined by influence, popularity, engagement and trust. Talkreview.com provides various metrics of blog and websites including unique visitor traffic estimates while Compete.com shows estimated site visitor traffic with option to compare to others. Interested to see how your website or blog is performing in terms of effectiveness and reach in addition to Compete.com, then check out talkreviews.com or Blog grader that looks at and reports on various blog metrics and information.

The sites and tools mentioned are far from an exhaustive listing of sites or metrics for various purposes, rather a sampling of what is available to meet different needs. For example there are Alexa, Goggle and Yahoo rankings among many others.

Wefollow as an example or discussion topic

One of the things that I find interesting is the diversity in the metrics and rankings for example if you were to say look at wefollow for a particularly category in the top 10 or 20, then use one or more of the other tools to see how the various rankings change.

A month or so ago I was curious to see if some of the sites could be gamed beyond running up the number of posts, tweets, followers or followings along with re tweets of which some sites appear to be influenced by. As part of determining what metrics matter and which to ignore or keep in the back pocket for when needed, I looked at and experiment with wefollow.

For those who might have been aware of what I was doing, I went from barely being visible for example in the storage category to jumping into the top 5. Then with some changes, was able to disappear from the top 5 and show up elsewhere and then when all was said and done, return to top rankings.

Does this mean I put a lot of stock or value in wefollow or simply use it as a gauge and metric along with all of the others? The answer is that it is just that, another metric and tool that can be used for gauging effectiveness and reach, or if you prefer, status or what ever your preference and objective are.

How did I change my rankings on wefollow? Simple, experimented with using various tags in different combinations, sometimes only one, sometimes many however keeping them relevant and then waiting several days. Im sure if you are inclined and have plenty of time on your hands, someone can figure out or find out how the actual algorithms work, however for me right now, I have other projects to pursue.

What is the best metric?

That is going to depends on your objectives or what you are trying to accomplish.

As with other measurements and metrics, those for social media provide different points of reference from how many followers to amount of influence.

Depending on your objective, effectiveness may be gauged by number of followers or those being followed, number of posts or the number of times being quoted or referenced by others including in lists.

In some cases rankings that compare with others are based on those sites knowing about you which may mean having to register so that you can be found.

Bottom line, metrics matter however what they mean and their importance will vary depending on objectives, preferences or for accomplishing different things.

One of the interesting things about social networking and media sites is that if you do not like a particularly ranking, list, grade or status then either work to change the influence of those scores, or, come up with your own.

What is your take on metrics that matter, which is of course unless they do not matter to you?

Ok, nuff said.

Its US Census time, What about IT Data Centers?

It is that once a decade activity time this year referred to as the US 2010 Census.

With the 2010 census underway, not to mention also time for completing and submitting your income tax returns, if you are in IT, what about measuring, assessing, taking inventory or analyzing your data and data center resources?

US 2010 Cenus formsUS 2010 Cenus forms
Figure 1: IT US 2010 Census forms

Have you recently taken a census of your data, data storage, servers, networks, hardware, software tools, services providers, media, maintenance agreements and licenses not to mention facilities?

Likewise have you figured out what if any taxes in terms of overhead or burden exists in your IT environment or where opportunities to become more optimized and efficient to get an IT resource refund of sorts are possible?

If not, now is a good time to take a census of your IT data center and associated resources in what might also be called an assessment, review, inventory or survey of what you have, how its being used, where and who is using and when along with associated configuration, performance, availability, security, compliance coverage along with costs and energy impact among other items.

IT Data Center Resources
Figure 2: IT Data Center Metrics for Planning and Forecasts

How much storage capacity do you have, how is it allocated along with being used?

What about storage performance, are you meeting response time and QoS objectives?

Lets not forget about availability, that is planned and unplanned downtime, how have your systems been behaving?

From an energy or power and cooling standpoint, what is the consumption along with metrics aligned to productivity and effectiveness. These include IOPS per watt, transactions per watt, videos or email along with web clicks or page views per watt, processor GHz per watt along with data movement bandwidth per watt and capacity stored per watt in a given footprint.

Other items to look into for data centers besides storage include servers, data and I/O networks, hardware, software, tools, services and other supplies along with physical facility with metrics such as PUE. Speaking of optimization, how is your environment doing, that is another advantage of doing a data center census.

For those who have completed and sent in your census material along with your 2009 tax returns, congratulations!

For others in the US who have not done so, now would be a good time to get going on those activities.

Likewise, regardless of what country or region you are in, its always a good time to take a census or inventory of your IT resources instead of waiting every ten years to do so.

Ok, nuff said.

PUE, Are you Managing Power, Energy or Productivity?

With a renewed focus on Green IT including energy Efficiency and Optimization of servers, storage, networks and facilities, is your focus on managing power, energy, or, productivity?

For example, do you use or are interested in metrics such as Greengrid PUE or 80 Plus efficient power supplies along with initiatives such as EPA Energy Star for servers and emerging Energy Star for Data Center for Storage in terms of energy usage?

Or are you interested in productivity such as amount of work or activity that can be done in a given amount of time,or how much information can be stored in a given footprint (power, cooling, floor space, budget, management)?

For many organizations, there tends to be a focus and in both managing power along with managing productivity. The two are or should interrelated, however there are some disconnects with some emphasis and metrics. For example, the Green grid PUE is a macro facilities centric metric that does not show the productivity, quality or measure of services being delivered by a data center or information factory. Instead, PUE provides a gauge of how the habitat, that is the building and power distribution along with cooling are efficient with respect to the total energy consumption of IT equipment.

As a refresher, PUE is a macro metric that is essentially a ratio of how much total power or energy goes into a facility vs. the amount of energy used by IT equipment. For example, if 12Kw (smaller room/site) or 12Mw (larger site) are required to power an IT data center or computer room for that matter, and of that energy load, 6kWh or 6Mw, the PUE would be 2. A PUE of 2 is an indicator that 50% of energy going to power a facility or computer room goes towards IT equipment (servers, storage, networks, telecom and related equipment) with the balance going towards running the facility or environment which typically has had the highest percentage being HVAC/cooling.

In the case of EPA Energy Star for Data Centers which initially is focused on the habitat or facility efficiency, the answer is measuring and managing energy use and facility efficiency as opposed to productivity or useful work. The metric for EPA Energy Star for Data Center initially will be Energy Usage Effectiveness (EUE) that will be used to calculate a ratting for a data center facility. Those data centers in the top25 percentile will qualify for Energy Star certification.

Note the word energy and not power which means that the data center macro metric based on Green grid PUE rating looks at all source of energy used by a data center and not just electrical power. What this means is that a macro and holistic facilities energy consumption could be a combination of electrical power, diesel, propane or natural gas or other fuel sources to generate or create power for IT equipment, HVAC/Cooling and other needs. By using a metric that factor in all energy sources, a facility that uses solar, radiant, heat pumps, economizers or other techniques to reduce demands on energy will make a better rating.

By using a macro metric such as EUE or PUE (ratio = Total_Power_Used / IT_Power_Needs), a starting point is available to decide and compare efficiency and cost to power or energize a facility or room also known as a habitat for technology.

Managing Productivity of Information Factories (E.g. Data Centers)
What EUE and PUE do not reflect or indicate is how much data is processed, moved and stored by servers, storage and networks within a facility. On the other hand or extreme from macro metrics are micro or component metrics that gauge energy usage on an individual device basis. Some of these micro metrics may have activity or productivity indicator measurements associated with them, some don’t. Where these leave a big gap and opportunity is to fill the span between the macro and micro.

This is where work is being done by various industry groups including SNIA GSI, SPC and SPEC among others along with EPA Energy Star among others to move beyond macro PUE indicators to more granular effectiveness and efficiency metrics that reflect productivity. Ultimately productivity is important to gauge,  the return on investment and business value of how much data can be processed by servers, moved via networks or stored on storage devices in a given energy footprint or cost.

In Figure 1 are shown four basic approaches (in addition to doing nothing) to energy efficiency. One approach is to avoid energy usage, similar to following a rationing model, but this approach will affect the amount of work that can be accomplished. Another approach is to do more work using the same amount of energy, boosting energy efficiency, or do same amount of work (or storage data) however with less energy.

The energy efficiency gap is the difference between the amount of work accomplished or information stored in a given footprint and the energy consumed. In other words, the bigger the energy efficiency gap, the better, as seen in the fourth scenario, doing more work or storing more information in a smaller footprint using less energy. Clock here to read more about Shifting from energy avoidance to energy efficiency.

Watch for new metrics looking at productivity and activity for servers, storage and networks ranging from MHz or GHz per watt, transactions or IOPS per watt, bandwidth, frames or packets processed per watt or capacity stored per watt in a given footprint. One of the confusing metrics is Gbytes or Tbytes per watt in that it can mean storage capacity or bandwidth, thus, understand the context of the metric. Likewise watch for metrics that reflect energy usage for active along with in-active including idle or dormant storage common with archives, backup or fixed content data.

What this all means is that work continues on developing usable and relevant metrics and measurement not only for macro energy usage, also, to gauge the effectiveness of delivering IT services. The business value proposition of driving efficiency and optimization including increased productivity along with storing more information in a given footprint is to support density and business sustainability.

Has SSD put Hard Disk Drives (HDDs) On Endangered Species List?

Storage I/O trends

Disclosure: I have been a user, vendor, author and analyst covering and a fan (and continue to be) of SSD for over 20 years

I have thought and wanting to post about this for a while, however recently several things popped up including moderating a panel where a vendor representative told the audience that the magnetic hard disk drive (HDD) would be dead in two, at most three years. While there were a few nods from those in the audience, the majority smiled politely, chuckled, looked at their watches or returned to doing email, twitters, texting or simply rolled their eyes in a way like, yeah right, we have heard this before ( ;) ).

Likewise, I have done many events including seminars, keynotes including at a recent CMG event (the performance and capacity planning group that I have been a part of for many years), webcasts and other interactions with IT pros, vendors, vars and media. These interactions have included among other topics, IT optimization, boosting server and storage efficiency, as well as the roll of tiering IT resources to boost efficiency, achieve better productivity while boosting performance in a cost-effective way during touch economic times, in other words, the other green IT!

Then the other day, I received an email from Mary Jander over at Internet Evolution. You may remember Mary from her days over at Byte & Switch. Mary was looking for a point, counter point, perspective and sound bit to a recent blog posting on her site and basically asked if I thought that the high performance HDD would be dead in a couple of years at the cost of FLASH SSD. Having given Mary some sound bits and perspectives which appear in her Article/Blog posting, there has since been a fun and lively discourse in Marys’ Internet Evolution blog comment section which could be seen by some as the pending funeral for high performance HDDs.

There has been a lot of work taking place including by industry trade groups such as the SNIA Solid State Storage Initiative (SSSI) among others, not to mention many claims, discussions, banter and even some trash talk about how the magnetic hard disk drives (HDD) that as a technology is over 50 years old now, is nearing the end of the road and is about to be replaced by FLASH SSD in the next two to three years depending on who you talk with or listen to.

That may very well be the case, however, I have a strong suspicion that while the high performance 3.5" Fibre Channel 15,500 Revolution per minute (15.5K RPM) HDD is nearing the end of the line, I don’t believe that the 2.5" small form factor (SFF) Serial Attached SCSI (SAS) 15.5K (maybe faster in the future?) high performance and larger capacity HDD will have met its demise in the two to three-year timeframe.

The reason I subscribe to this notion is that of a need for balancing performance, availability, capacity, energy to a given power, cooling, floor space and environmental need along with price to meet different tiers of application and data quality of service and service level needs. Simply put, there continues to be a need even with some the new or emerging enhanced intelligence capabilities of storage systems for tiered media. That is tier-0 ultra fast SSD (FLASH or RAM) in a 2.5" form factor with SATA shifting to SAS connectivity, tier-1 fast 2.5" SAS 15.5K large capacity HDDs, tier-2 2.5" SATA and SAS high-capacity, 5.4 to 10K HDDs, or, ultra large capacity SAS and SATA 3.5" HDDs to meet different performance, availability, capacity, energy and economic points.

Why not just use SSD FLASH for all high performance activity, after all it excels in reads correct? Yup, however, take a closer look at write performance which is getting better and better, even with less reliance on intelligent controllers, firmware and RAM as a buffer. However, there is still a need for a balance of Tier-0, Tier-1, Tier-2, Tier-3 etc mediums to balance different requirements and stretch strained IT budgets to do more efficiency.

Maybe I’m stuck in my ways and spend to much time talking with IT professionals including server or storage architects, as well as IT planners, purchasers and others in the trenches and not enough time drinking the cool-aid and believing the evangelists and truth squads ;). However there is certainly no denying that Solid State Devices (SSD) using either RAM or FLASH are back in the spotlight again as SSD has been in the past, this time for many reasons with adoption continuing to grow. I think that its safe to say that some HDDs will fade away like other earlier generations have, such as the 3.5" FC HDD, however other HDDs like the high performance 2.5" SAS HDDs have some time to enjoy before their funeral or wake.

What say you?

BTW, check out this popular (and its Free) StorageIO Industry Trends and Perspectives White Paper Report that looks at various data center performance bottlenecks and how to discuss them to transition towards becoming more efficient. However a warning, you might actually be inclined to jump on the SSD bandwagon.

Oh, and there’s nothing wrong with SSD, after all as I mentioned earlier, I’m a huge fan, however, I’m also a huge fan of spinning HDDs having skipped SSD in my latest computer purchases for fast 7.2K (or faster) HDDs with FLASH for portability (encrypted of course). After all, it’s also about balancing the different tiers of storage mediums to the task at hand, that is, unless you subscribe to the notion that one tool or technique should be used to solve all problems which is fine if that is your cup of tea.

Storage Effiency and Optimizaiton – Balancing Time and Space

Storage I/O trends

Here’s a link to the presentation I recently delivered at the Spring 2009 Minneapolis/St. Paul area CMG (Computer Measurement Group – CMG) March 20th, 2009 hosted by Nexus Information Systems and organized by Tom Becchetti. The theme of the event was "Is your storage efficient? There are many ways to rate your storage, how does yours stack up?". Tom organized a great event as usual with a diverse set of speakers for the well attended event graciously hosted by Keith Norbie of Nexus at their Minnetonka facility. The title of my presentation was "Storage Efficiency: Mirror Mirror On The Wall, Who or What is The Most Efficient of Them All? Finding the Correct Balance" that looked at balancing the need to reduce (or maximize) space (utilization) with time (performance) to meet different requirements including maintaining quality of service, response time and availability.

Keeping in mind that there is no such thing as a data or I/O performance recession, there is a common myth that storage optimization or efficiency is all about driving up storage space capacity utilization which can be true for some environments, applications, data or storage types. However there is also the need to maintain or boost performance, reduce response time and latency, doing more work in a more productive and efficieny manner. Not all data or storage can be consolidated to boost utilization without concern for degrading or in any other way penalizing performance, response time or availability.

Thus it is about time and space, that is, balancing data movement and processing rates with storage space capacity utilization and that sometimes, more is not better for performance when it comes to ratios or the number of components in a solution.

Likewise there is the need to balance energy avoidance with energy efficient, balancing the need to store more data in a smaller footprint using less energy and the need to process more data in less time efficiently for productivity.

These and other related themes are expanded on in more detail in my book "The Green and Virtual Data Center" (CRC). These and other related themes will covered in one of my upcoming presentations (The Other Green — Storage Efficiency and Optimization) at StorageDecisions in Chicago the week of June 1st, 2009, as well as in various seminars and events that I will be involved in the coming weeks and months.

Thanks to all those who helped organize, support, sponsored, presented and attended the recent CMG event, look forward to seeing or hearing from you all again soon.
