Shifting from energy avoidance to energy efficiency

Storage I/O trends

I’m continually amazed at the number of people in the IT industry from customers to vendors, vars to media and even analysts who associate Green IT with and only with reducing carbon footprints. I guess I should not be surprised given the amount of rhetoric around Green and carbon both in the IT industry as well as in general resulting in a Green Gap.

The reality as I have discussed in the past is that Green IT while addressing carbon footprint topics, is really more about efficiency and optimization for business economic benefits that also help the environment. From a near-term tactical perspective, Green IT is about boosting productivity and enabling business sustainability during tough economic times, doing more with less, or, doing more with what you have. On a strategic basis, Green IT is about continued sustainability while also improving top and bottom line economics and repositioning IT as a competitive advantage resource.

There is a lot of focus on energy avoidance, as it is relatively easy to understand and it is also easy to implement. Turning off the lights, turning off devices when they are not in use, enabling low-power, energy-savings or Energy Star® (now implemented for servers with storage being a new focus) modes are all means to saving or reducing energy consumption, emissions, and energy bills.

Ideal candidates for powering down when not in use or inactive include desktop workstations, PCs, laptops, and associated video monitors and printers. Turning lights off or implementing motion detectors to turn lights off automatically, along with powering off or enabling energy-saving modes on general-purpose and consumer products has a significant benefit. New generations of processors such as the Intel Xeon 5xxx or 7xxx series (formerly known as Nehalem) provide the ability to boost performance when needed, or, go into various energy conservation modes when possible to balance performance, availability and energy needs to applicable service requirements, a form of intelligent power management.

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 the complement—do the same work using less energy.

Tiered Storage
Figure 1 the Many Faces of Energy Efficiency (Source: “The Green and Virtual Data Center” (CRC)

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.

Given the shared nature of their use along with various intersystem dependencies, not all data center resources can be powered off completely. Some forms of storage devices can be powered off when they are not in use, such as offline storage devices or mediums for backups and archiving. Technologies such as magnetic tape or removable hard disk drives that do not need power when they are not in use can be used for storing inactive and dormant data.

Avoiding energy use can be part of an approach to address power, cooling, floor space and environmental (PCFE) challenges, particularly for servers, storage, and networks that do not need to be used or accessible at all times. However, not all applications, data or workloads can be consolidated, or, powered down due to performance, availability, capacity, security, compatibility, politics, financial and many other reasons. For those applications that cannot be consolidated, the trick is to support them in a more efficient and effective means.

Simply put, when work needs to be done or information needs to be stored or retrieved or data moved, it should be done so in the most energy-efficient manner aligned to a given level of service which can mean leveraging faster, higher performing resources (servers, storage and networks) to get the job done fast resulting in improved productivity and efficiency.

Tiering is an approach that applies to servers, storage, and networks as well as data protection. For example, tiered servers include large frame or mainframes, rack mount as well as blades with various amounts of memory, I/O or expansion slots and number of processor cores at different speeds. Tiered storage includes different types of mediums and storage system architectures such as those shown in figure 2. Tiered networking or tiered access includes 10Gb and 1Gb Ethernet, 2/4/8 Gb Fibre Channel, Fibre Channel over Ethernet (FCoE), iSCSI, NAS and shared SAS among others. Tiered data protection includes various technologies to meet various recovery time objectives (RTO) and recovery point objectives (RPO) such as real-time synchronous mirroring with snapshots, to periodic backup to disk or tape among other approaches, techniques and technologies.

Technology alignment (Figure 2), that is aligning the applicable type of storage or server resource and devices to the task at hand to meet application service requirements is essential to archiving an optimized and efficient IT environment. For example, for very I/O intensive active data as shown in figure 2, leveraging ultra fast tier-0 high-performance SSD (FLASH or RAM) storage, or for high I/O active data, tier-1 fast 15.5K SAS and Fibre Channel storage based systems would be applicable.

For active and on-line data, that’s where energy efficiency in the form of fast disk drives including RAM SSD or FLASH SSD (for reads, writes are another story) and in particular fast 15.5K or 10K FC and SAS energy efficient disks and their associated storage systems come into play. The focus for active data and storage systems should be around more useful work per unit of energy consumed in a given footprint. For example, more IOPS per watt, more transactions per watt, more bandwidth or video streams per watt, more files or emails processed per watt.

Tiered Storage

Figure 2 Tiered Storage: Balancing Performance, Availability, Capacity and Energy to QoS (Source: “The Green and Virtual Data Center” (CRC)

For low-performance, low activity applications where the focus is around storing as much data as possible with the lowest cost including for disk to disk based backup, slower high capacity SATA based storage systems are the fit (lower right in figure 2). For long-term bulk storage to meet archiving, data retention or other retention needs as well as storing large monthly full backups or long term data preservation, tape remains the ticket for large environments with the best combination of performance, availability capacity and energy efficiency and cost per footprint.

General approaches to boost energy efficiency include:

  • Do more work using the same or less amount of power and subsequently cooling
  • Leverage faster processors/controllers that use the same or less power
  • Apply applicable RAID level to application and data QoS requirements
  • Consolidate slower storage or servers to a faster, more energy-efficient solution
  • Use faster disk drives with capacity boost and that draw less power
  • Upgrade to newer, faster, denser, more energy-efficient technologies
  • Look beyond capacity utilization; keep response time and availability in mind
  • Leverage IPM, AVS, and other techniques to vary performance and energy usage
  • Manage data both locally and remote; gain control and insight before moving problems
  • Leverage a data footprint reduction strategy across all data and storage tiers
  • Utilize multiple data footprint techniques including archive, compression and de-dupe
  • Reduce data footprint impact, enabling higher densities of stored on-line data

Find a balance between energy avoidance and energy efficiency, consolidation and business enablement for sustainably, hardware and software, best practices including policy and producers, as well as leveraging available financial rebates and incentives. Addressing green and PCFE issues is a process; there is no one single solution or magic formula.

Efficient and Optimized IT Wheel of Oppourtunity

Figure 3 Wheel of Opportunity – Various Techniques and Technologies for Infrastructure Optimization (Source: “The Green and Virtual Data Center” (CRC)

Instead, leverage a combination of technologies, techniques, and best practices to address various issues and requirements is needed (Figure 3). Some technologies and techniques include among others infrastructure resource management (IRM), data management, archiving (including for non-compliance), and compression (on-line and off-line, primary and secondary) as well as de-dupe for backups, space saving snapshots, and effective use of applicable raid levels.

Green washing and green hype may fade away, however power, cooling, footprint, energy (PCFE) and related issues and initiatives that enable IT infrastructure optimization and business sustainability will not fade away. Addressing IT infrastructure optimization and efficiency is thus essential to IT and business sustainability and growth in an environmentally friendly manner which enables shifting from talking about green to being green and efficient.

Catch of the day or post of the day!

Ok, I know, its been a couple of weeks since my last post. Sure I have been tweeting now and then, attending several briefings with new emerging as well as existing vendors for up-coming announcements, not to mention getting some other content out from webcasts, to podcasts, or videos, interviews, articles, tips and presentations at various events, pertaining to Green IT, virtualization, cloud storage and computing, backup, data protection, performance, capacity planning among other topics.

Anyway, for now a quick post as I have many others that I have been wanting to do and will be doing soon, however wanted to get a few things out sooner vs. later, and after all, all work and no play makes for a dull day right?

Well, last week after spending a couple of days in Chicago at Storage Decisions where I presented a couple of sessions and recorded several videos, I had a chance to get out and do some fishing and catching. Fishing is always great, however catching (and release) is even more fun, especially when you can catch some, toss some, and keep some for dinner which is what occurred last week when my friend Rob and me ventured out for a couple of hours and found where the fish were (see picture) on the St. Croix river.

Catch of the Day

Rob on left (Bruins warm up jacket for Bass fishing), Greg on the right (Mustang PFD Jacket)

Catch of the day line-up
From right to left, bottle bass (caught at the dock ;) ), stripped bass, northern pike (swamp shark), more stripped bass, and another bottle bass (also caught at the dock).

Ok, nuff fish talk for now, back to work, get a few things done, and then maybe this weekend, get another blog post done, maybe some fishing, and enjoying the summer weather before heading off to Toronto on Monday for Storage Decisions on Tuesday, then a couple of webcasts and web radio events on Wednesday among other activities.

Determining Computer or Server Energy Use

Recently I posted a response to a question over at IT Knowledge Exchange (e.g. ITKE) about how to determine power or energy use.

In a nutshell:

Depending on what you are looking for, or trying to accomplish, you may, or may not need a formula per say.

For example, if all you need to know is how many volts, amps, watts, kva, or btu’s are used by a particular computer or other IT device for that matter, first things first check the “tag” or “label” on the device as well as included documentation, or, on-line spec sheets and documentation.

There are also some measuring devices including among others Kill A Watt that you can plug a device into and see volts, amps, watts, and so forth.

Ok, that might have been the obvious and easy part, now on to the next step.

Often a name plate may give kva however not watts, or perhaps amps and volts however not kva or some other metric. This is where the various conversion formulas come into play.

For example, if you know volts and amps, you can get watts, if you know kva along with watts, amps or volts, you can derive the others, or, if you have btus, you can watts, or if you know watts you can get btus and so forth.

Btu/Hour = watts * 3.413
Watts = Btu/Hour * 0.293
Watts = Amps * Volts
Volts = Watts / Amps
Amps = Watts / Volts
VoltAmps (Va) = Volts * amps
KVA = (Volts * Amps) / 1000

Here’s a link to some additional conversions and formulas that along with many others are found in my new book “The Green and Virtual Data Center” (CRC).

www.thegreenandvirtualdatacenter.com/greenmetrics.html

In “The Green and Virtual Data Center” (CRC). book, there is an entire chapter on metrics, where and how to find them, formulas, conversions as well as other related items including determining energy costs, carbon footprints, cooling and more across servers, storage, networks, facilities along with associated management tools.

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.

IBM Out, Oracle In as Buyer of Sun

Following on the heals of IBM in talks with Sun that broke down a week or so ago, today’s news is Oracle has agreed to buy Sun extending Larry Ellison’s software empire as well as boosting his hardware empire from fast sport platforms to server, storage and other IT data center hardware.

What’s the real play and story here is certainly open to discussion and debate, is it good, is it bad, who are the winners and losers will be determined as the dust settles, not to mention as responses from across the industry, not to mention new product announcements and enhances slated by some for as early as this week. What if any role does Cisco wanting to get into servers and maybe storage play, does Oracle want to make sure they remain at the big table?

Regarding discussions of this deal, what it means, the twitter world has been abuzz already this morning, click here to see and follow some of the conversations, perspectives and insights being exchanged.

Nuf said for now, its time to get ready to head off to the airport as I’m doing several events speaking and keynote sessions this week on the right coast while the left coast is abuzz with the Sun & Oracle activity.

Ok, nuff said.

Storage Decisions Spring 2009 Sessions Update

StorageDecisions Logo

The conference lineup and details for the Spring 2009 Storage Decisions event (June 1st and 2nd) in Chicago is coming together including two talks/presentations that I will be doing. One will be in Track 2 (Disaster Recovery) titled "Server Virtualization, Business Continuance and Disaster Recovery" and the other in Track 6 (Management/Executive) titled "The Other Green — Storage Efficiency and Optimization" with both sessions leveraging themes and topics from my new book "The Green and Virtual Data Center" (CRC).

Track 2: Disaster Recovery
Server Virtualization, Business Continuance and Disaster Recovery
Presented by Greg Schulz, Founder and Senior Analyst, StorageIO
Server virtualization has the potential to bring sophisticated business continuance (BC) and disaster recovery (DR) techniques to organizations that previously didn’t have the means to adopt them. Likewise, virtualized as well as cloud environments need to be included in a BC/DR plan to enable application and data availability. Learn tips and tricks on building an accessible BC/DR strategy and plan using server virtualization and the storage products that enable efficient, flexible green and virtual data centers.

Topics include:
* Cross technology domain data protection management
* Tiered data protection to stretch your IT budget dollar
* What’s needed to enable BC/DR for virtualized environments
* How virtualization can enable BC/DR for non-virtualized environments
* General HA, BC/DR and data protection tips for virtual environments

Track 6: Management/Executive
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 include:
* Energy efficiency (strategic) vs. energy avoidance (tactical)
* Optimization and the need for speed vs. the need for capacity
* Metrics and measurements for management insight
* Tiered storage and tiered access including SSD, FC, SAS and clouds
* Data footprint reduction (archive, compress, dedupe) and thin provision
* Best practices, financial incentives and what you can do today

See you in Chicago in June if not before then. Learn more about other upcoming events and activities on the StorageIO events page.

March and Mileage Mania Wrap-up

Today’s flight to Santa Ana (SNA) Orange County California for an 18 hour visit marks my 3rd trip to the left coast in the past four weeks that started out with a trip to Los Angeles. The purpose of today’s trip is to deliver a talk around Business Continuance (BC) and Disaster recovery (DR) topics for virtual server and storage environments along with related data transformation topics themes, part of a series of on-going events.

Planned flight path from MSP to SNA, note upper midwest snow storms. Thanks to Northwest Airlines, now part of Delta!
Planned flight path from MSP to SNA courtesy of Northwest Airlines, now part of Delta

This is a short trip to southern California in that I have to be back in Minneapolis for a Wednesday afternoon meeting followed by keynoting at an IT Infrastructure Optimization Seminar downtown Minneapolis Thursday morning. Right after Thursday morning session, its off to the other coast for some Friday morning and early afternoon sessions in the Boston area, the results of which I hope to be able to share with you in a not so distant future posting.

Where has March gone? Its been a busy and fun month out on the road with in-person seminars, vendor and user group events in Minneapolis, Los Angles, Las Vegas, Milwaukee, Atlanta, St. Louis, Birmingham, Minneapolis for CMG user group, Cincinnati and Orange County not to mention some other meetings and consulting engagements elsewhere including participating in a couple of webcast and virtual conference/seminars while on the road. Coverage and discussion around my new book "The Green and Virtual Data Center" (CRC) continues expand, read here to see what’s being said.

What has made the month fun in addition to traveling around the country is the interaction with the hundreds of IT professionals from organizations of all size hearing what they are encountering, what their challenges are, what they are thinking, and in general what’s on their mind.

Some of the common themes include:

  • There’s no such thing as a data recession, however the result is doing more with less, or, with what you have
  • Confusion abounds around green hype including carbon footprints vs. core IT and business issues
  • There is life beyond consolidation for server and storage virtualization to enable business agility
  • Security and encryption remain popular topic as does heterogeneous and affordable key management
  • End to end IT resource management for virtual environments is needed that is scalable and affordable
  • Performance and quality of service can not be sacrificed in the quest to drive up storage utilization
  • Clouds, SSD (FLASH), Dedupe, FCoE and Thin Provisioning among others are on the watch list
  • Tape continues to be used complimenting disks in tiered storage environments along with VTLs
  • Dedupe continues to be deployed and we are just seeing the very tip of the ice-berg of opportunity
  • Software licensing cost savings or reallocation should be a next step focus for virtual environments
  • Now, for a bit of irony and humor, overheard was a server sales person talking to a storage sales person comparing notes on how they are missing their forecasts as their customers are buying fewer servers and storage now that they are consolidating with virtualization, or using disk dedupe to eliminate disk drives. Doh!!!

    Now if those sales people can get their marketing folks to get them the play book for virtualization for business agility, improving performance and enabling business growth in an optimized, transformed environment, they might be able to talk a different story with their customers for new opportunities…

    What’s on deck for April? More of the same, however also watch and listen for some additional web based content including interviews quotes and perspectives on industry happenings, articles, tips and columns, reports, blogs, videos, podcasts, webcasts and twitter activity as well as appearances at events in Boston, Chicago, New Jersey and Providence among other venues.

    To all of those who came out to the various events in March, thank you very much and look forward to future follow-up conversations as well as seeing you at some of the upcoming future events.

    Cheers gs

    Out and About Update

    As part of the continuing on the road theme and series, this post is being done while traveling for this weeks adventures and events including stops in Atlanta, St. Louis and wrapping up the week in Minneapolis at the local CMG quarterly meeting event. At both last weeks events in Las Vegas and Milwaukee as well as this weeks events talking with IT professionals from various organizations, a consistent theme is that there is no data or I/O recession, however there is the need to do more with less while enabling business sustainability.

    While VMware remains the dominant server virtualization platform, I’m hearing of more organizations using Citrix or other Xensource based technologies along with some Microsoft HyperV adopters in part to leverage lower cost of ownership compared to VMware in instances where not all of the feature functionality of the robust VMware technology is needed. This will be an interesting scenario to keep an eye on in the weeks and months to come to see if there are any shifting patterns on the server virtualization front while trying to stretch IT dollars further to do more.

    On the Merger & Acquisition (M&A) scene, coverage of on again, off-again and recently rekindled rumored of IBM buying Sun is rampant from the Wall Street Journal to twitter and most points in between. There have been many storm clouds around Sun the past several years from a business and technology perspective, and perhaps the best thing is for Sun and IBM to combine forces and resources, bridging the gap between old physical worlds and new virtual cloud enabled worlds so to speak. Personally, I like the idea for many different reasons and think that some shape or form of an IBM and Sun deal either in entirety, or pieces is far more likely to occur and sooner, than seeing funds returned from either AIG or Bernard Madoff, the other top news items this week, nuf said for now about IBM and Sun.

    Also this week, other activity included Cisco announcing that they are testing the waters to enter into the server market space to help jumpstart the converged networking space with some of my initial comments here and here. Check out StorageIO in the news page here for other comments on various IT industry trends, technologies and related activities including a recent piece by Drew Robb about The State of the Data Storage Job Market.

    Lets see how this plays out with more to say later, thanks again for everyone who came out for last weeks as well as this weeks events, look forward to seeing and talking with you again soon I hope.

    Cheers – gs

    Work and Entertainment From Coast to Coast

    A week ago I was in St. Petersburg, Tampa and Miami Florida for a mix of work and relaxation along with Karen (Mrs. Schulz), visiting with my cousin and her husband who lives in the St. Pete beach area for a few days before back to work. While in the St. Pete and Tampa area, for fun, we did an afternoon at Busch Garden including a ride on Montu. For those who have not ridden on Montu, here’s a video I found that someone recorded to help give you a perspective of the ride. Other fun activities included stops or time at Billys Stonecrab and Seafood joint, Kayaking, lounging pool-side, shelling at Ft. Desoto and St. Pete Beach as well as a visit to the Hurricane among others.

    In Miami, the pool area at the Four Seasons including a nice cabana pool-side spot to escape the cool breeze made for a great relaxing and catch-up on some work spot while Karen relaxed in the sun. Some of the restraunts in Miami we visited when taking a break from work included Gordon Birsch and Rosa for some outstanding, made at the table side fresh Guacamole en Molcajet!.

    Speaking of work, the Florida trip involved doing keynotes at events in both Tampa and Miami with a theme of IT Infrastructure Optimization with both events being well attended. Themes included doing more with less, or, doing more with what you have, addressing data footprint and data management to boost productivity, how to address the continued growth in data and need to process, move and store more data and information. A discussion point prompted the thought of if there is a data recession or not (See previous blog post and here). Other topics of discussion and interested included converged networking for voice, data and general networking, security, server and storage virtualization, performance and capacity planning, data protection and BC/DR among others.

    This past week involved a lunch and learn Keynote in the Minneapolis area with a local VAR, before a quick trip to the other (left) coast for another IT Infrastructure Optimization session and keynote, this time in Los Angeles. Some common themes heard from IT professionals at this past weeks events echoed those heard in Florida as well as concern about managing encryption keys not to mention securing virtual environments and software licensing models in virtualized server environments. The trip to LA also enabled a quick visit with friend Bruce Rave of Go Deep fame who provided a great tour and sightseeing of the Hollywood music scene.

    Hollywood stops included dinner at Genghis Cohens (The duck and cashew chicken were outstanding) followed by visits to the Cat and Fiddle and Infamous Rainbow Bar & Grill next door to legendary Roxy. People watching was great as was the music and ambiance including a Nikki Sixx of Motely Crew sighting at the Rainbow as well as Dr. Sanjay Gupta of CNN seen in hotel lobby minutes after appearing on Larry King Live.

    Thanks too everyone who came out and participated in the seminar events in Tampa, Miami, Minneapolis and LA, look forward to seeing and hearing from you again soon. Now its time to get ready to head off too the airport for this weeks events and activities including stops in Las Vegas and Milwaukee among others.

    Cheers

    On The Road Again: An Update

    A while back, I posted about a busy upcoming spring schedule of activity and events, and then a few weeks ago, posted an update, so this can be considered the latest "On The Road Again" update. While the economy continues to be in rough condition and job reductions or layoffs continuing, or, reduction in hours or employees being asked to take time off without pay or to take sabbaticals, not to mention the race to get the economic stimulus bill passed, for many people, business and life goes on.

    Airport parking lots have plenty of cars in them, airplanes while not always full, are not empty (granted there has been some fleet optimization aka aligning capacity to best suited tier of aircraft and other consolidation or capacity improvements). Many organizations cutting back on travel and entertainment (T&E) spending, either to watch the top and bottom line, avoid being perceived or seen on the news as having employees going on junkets when they may in fact being going to conferences, seminars, conventions or other educational and related events to boost skills and seek out ways to improve business productivity.

    One of the reason that I have a busy travel schedule in addition to my normal analyst and consulting activities is that many events and seminars are being scheduled close to, or in the cities where IT professionals are located who might otherwise have T&E restrictions or other constraints from traveling to industry events, some of which are or will be impacted by recent economic and business conditions.

    Last week I was invited to attend and speak at the FujiFilm Executive Seminar, no private jets were used or seen, travel was via scheduled air carriers (coach air-fare). FujiFilm has a nice program for those interested in or involved with tape whether for disk to tape backup, disk to disk to tape, long term archive, bulk storage and other scenarios involving the continued use and changing roles of tape as a green data storage medium for in-active or off-line data. Check out FujiFilm TapePower Center portal.

    This past week I was in the big "D", that’s Dallas Texas to do another TechTarget Dinner event around the theme of BC/DR, Virtualization and IT optimization. The session was well attended by a diverse audience of IT professionals from around the DFW metroplex. Common themes included discussions about business and economic activity as well as the need to keep business and IT running even when budgets are being stretched further and further. Technology conversations included server and storage virtualization, tiered storage including SSD, fast FC and SAS disk drives, lower performance high capacity "fat" disk drives as well as tape not to mention tiered data protection, tiered servers and other related items.

    The Green Gap continues to manifest itself in that when asked, most people do not have Green IT initiatives, however, when asked they do have power, cooling, floor-space, environmental (PCFE) or business economic sustainability concerns, aka, the rest of the Green story.

    While some attendees have started to use some new technologies including dedupe technology, most I find are still using a combination of disk and tape with some considering dedupe for the future for certain applications. Other technologies and trends being watched, however also ones with concerns as to their stability and viability for enterprise use include FLASH based SSD, Cloud computing and thin provisioning among others. Common themes I hear from IT professionals are that these are technologies and tools to keep an eye on, or, use on a selective basis and are essentially tiered resources to have in a tool box of technologies to apply to different tasks to meet various service requirements. Hopefully the Cowboys can put a fraction of the amount of energy and interest into and improving their environment that the Dallas area IT folks are applying to their environments, especially given the strained IT budgets vs. the budget that the Cowboys have to work with for their player personal.

    I always find it interesting when talking to groups of IT professionals which tend to be enterprise, SME and SMB hearing what they are doing and looking at or considering which often is in stark contrast to some of the survey results on technology adoption trends one commonly reads or hears about. Hummm, nuff said, what say you?

    Hope to see you at one of the many upcoming events perhaps coming to a venue near you.

    Cheers gs

    Server and Storage Virtualization – Life beyond Consolidation

    Storage I/O trends

    Ask someone what virtualization of IT servers or storage means and the typical response is to consolidate under-utilized physical servers or storage systems to reduce power, cooling, floor space and physical hardware costs.  However I commonly hear from IT professionals that not all of their servers or storage can be consolidated for various reasons. Some reasons why IT resources such as servers or storage cannot be consolidated include among others While consolidation is one the faces or capabilities, and certainly a common usage today, there are many other quality of service (QoS), performance, politics, financial ownership, security, software compatibility and vendor support to name a few.

    In the big picture, the percentage of all servers (or storage) that can be  consolidated ranges from as low as 15% to as high as 35%, or perhaps higher (or lower) depending on whose numbers you subscribe to. Likewise, the percentage of virtualized servers that have been virtualized for consolidation purposes is generally considered to be in the high 77-94% percent range based on different estimates.

    What this means, is that while the benefits of leveraging consolidation via server virtualization are well-known, not all servers can be consolidated for different reasons and the same holds true for storage and other IT resources. However, this does not mean that the majority of servers, storage or other IT resources cannot be virtualized to enable transparent management for maintenance, technology updates, load-balancing, supporting business continuance (BC) or disaster recovery (DR) along with other non consolidation centric functions. In other words, with consolidation, we are just seeing the tip of the virtualization iceberg (or mountain).

    There are several faces or functionality of virtualization technologies beyond consolidation including abstraction, emulation and providing transparency for enabling enhanced management and flexibility of IT resources. For example, virtual tape libraries leverage abstraction and emulation to enable new disk based technologies that combine replication, compression and de-duplication to cut  data footprint and enable BC/DR to co-exist with existing backup and data protection software, processes and procedures. Another example is using server or storage virtualization to provide an abstraction layer to support BC/DR enabling transparent movement of applications for consolidated, as well as non-consolidated servers. Technology upgrades are another time consuming and disruptive process where virtualization can be used to more seamlessly move applications and data while reducing or eliminating application downtime. In other words, the focus today is clearly on consolidation to drive up utilization and reduce costs; however there are even greater opportunities on a go forward basis for using different aspects of virtualization

    Note that this does not mean however that not all servers or storage cannot be virtualized, something that is a common misperception given the perception and industry messaging that incorrectly pigeon holes virtualization to mean consolidation, and consolidation to mean virtualization. To the contrary, the reality is that there is life beyond consolidation, there are even more scenarios and far greater market opportunity for non-consolidation virtualization deployments over time, then what has already been seen for first wave of consolidation centric virtualization scenarios.

    There is a very large market opportunity for virtualization of servers, storage and I/O networking in scenarios beyond consolidation for enabling transparent data and application movement, supporting BC/DR and other common time-consuming and disruptive IT infrastructure resource management tasks.

    Ok, nuff said.
