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 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.

Odds and Ends – Getting Caught Up, News and Other Updates

This post is a collection of various odds and ends, news and updates as Im getting caught up on some things.

Here’s a link to the first of what will be a series of up-coming short articles appearing at Byte and Switch related to my new book "The Green and Virtual Data Center" (CRC). The first installment appeared recently and is titled "Green IT & the Green Gap" and the theme of the installment is that in going green, you enable a business to grow, diversify, and expand its use of IT, all of which have economic benefits. Learn more about the green gap here.

Also over at Byte and Switch, Paul Travis recently did an article "Going Green & the Economic Downturn" that takes a look the shifting green focus to that around economic and cost cutting opportunities during current finical turmoil. Also on the Green front, Drew Robb has an interesting article talking about server and IT data center "Green IT Myths vs. Realities" appearing in ServerWatch. Another new green and economic sustainability for IT data center article can be found over at Greener Computing with a link here. While on the topic of my new book, writer and blogger, Heather Clancy has some comments about "The Green and Virtual Data Center" (CRC) over at ZDNET. Dave Simpson of InfoStor fame has a blog post as well that mentions my new book, check it out here. Also, check out this posting over at Datacenterlinks blogsite as well as a post over at Green Data Center blog site.

Meanwhile inventory and book availability continue to improve at Amazon.com and other venues around the world as back-logs from pre-orders and initial book sales resulted in some sell-out or initial limited availability. My publisher CRC informs me that plenty of books are flowing out and into the distribution supply chain to meet risking demand including bulk and special promotional and educational sales. Thanks to all of you have obtained copies of my new book, drop me a note with your comments and feedback when you get a chance. Also watch for additional book news, reviews, reports and other programs to be announced over the coming weeks.

For addressing data center bottlenecks, on the tiered storage and Solid State Device (SSD) front, that’s for both RAM and FLASH based, here’s an article over at Processor.com worth a look at. Here are a couple of other recent articles over at Processor.com addressing small form factor servers and refurbished servers, as well as freeing up data center space. Steve Kovosky has an interesting blog post over at Virtualization Conversation about Virtualization: Life Beyond Consolidation building on a previous blog posting I did a few weeks back pertaining to server and storage virtualization trends and directions. Here’s a recent article by Paul Shread over at Enterprise Storage Forum about T10 Object Storage Devices (OSD) and their current status or lack of progress including Sun’s shifting focus.

Speaking of data protection for physical and virtual environments, tape, data protection management, monitoring and managing IT resource effectiveness not to mention stretching your IT budget dollar, here’s a link to an article over at CTR in which yours truly provides some commentary. Also on the data protection theme, Walaika Haskins over at TechNewsWorld has a good article about "Figuring Out the Best Way to Stash Your Data". Data dedupe continues to be a popular topic for discussion and Cindy Waxer recently wrote an article appearing at Inc. Technology pertaining to Dedupe and Disaster Recovery (DR) and Business Continence (BC). Also on the dedupe front, here’s a industry trends and perspective solutions brief over on the EMC site pertaining to policy based data dedupe deployment (don’t worry, its not a data dedupe debate document, however I suppose some of the Drs’ and Divas’ of Dedupe may see it that way which will give them something to debate ;) ) with a focus around when to use which type or mode of dedupe processing to meet different applications requirements (may require registration, however its free, the document that is).

Is There a Data and I/O Activity Recession?

Storage I/O trends

With all the focus on both domestic and international economic woes and discussion of recessions and depressions and possible future rapid inflation, recent conversations with IT professionals from organizations of all size across different industry sectors and geographies prompted the question, is there also a data and I/O activity recession?

Here’s the premise, if you listen to current economic and financial reports as well as employment information, the immediate conclusion is that yes, there should also be an I recession in the form of contraction in the amount of data being processed, moved and stored which would also impact I/O (e.g. DAS,, LAN, SAN, FAN or NAS, MAN, WAN) networking activity as well. After all, the server, storage, I/O and networking vendors earnings are all being impacted right?

As is often the case, there is more to the story, certainly vendor earnings are down and some vendors are shipping less product than during corresponding periods from a year or more ago. Likewise, I continue to hear from both IT organizations, vars and vendors of lengthened sales cycles due to increased due diligence and more security of IT acquisitions meaning that sales and revenue forecasts continue to be very volatile with some vendors pulling back on their future financial guidance.

However, does that mean fewer servers, storage, I/O and networking components not to mention less software is being shipped? In some cases there is or has been a slow down. However in other cases, due to pricing pressures, increased performance and capacity density where more work can be done by fewer devices, consolidation, data footprint reduction, optimization, virtualization including VMware and other techniques, not to mention a decrease in some activity, there is less demand. On the other hand, while some retail vendors are seeing their business volume decrease, others such as Amazon are seeing continued heavy demand and activity.

Been on a trip lately through an airport? Granted the airlines have instituted capacity management (e.g. capacity planning) and fleet optimization to align the number of flights or frequency as well as aircraft type (tiering) to the demand. In some cases smaller planes, in other cases larger planes, for some more stops at a lower price (trade time for money) or in other cases shorter direct routes for a higher fee. The point being is that while there is an economic recession underway, and granted there are fewer flights, many if not most of those flights are full which means transactions and information to process by the airlines reservations and operational as well as customer relations and loyalty systems.

Mergers and acquisitions usually mean a reduction or consolidation of activity resulting in excess and surplus technologies, yet talking with some financial services organizations, over time some of their systems will be consolidated to achieve operating efficiency and synergies, near term, in some cases, there is the need for more IT resources to support the increased activity of supporting multiple applications, increased customer inquiry and conversion activity.

On a go forward basis, there is the need to support more applications and services that will generate more I/O activity to enable data to be moved, processed and stored. Not to mention, data being retained in multiple locations for longer periods of time to meet both compliance and non regulatory compliance requirements as well as for BC/DR and business intelligence (BI) or data mining for marketing and other purposes.

Speaking of the financial sector, while the economic value of most securities is depressed, and with the wild valuation swings in the stock markets, the result is more data to process, move and store on a daily basis, all of which continues to place more demand on IT infrastructure resources including servers, storage, I/O networking, software, facilities and the people to support them.

Dow Jones Trading Activity Volume (Courtesy of data360.org)

For example, the amount of Dow Jones trading activity is on a logarithmic upward trend curve in the example chart from data360.org which means more transactions selling and buying. The result of more transactions is that there are also an increase in the number of back-office functions for settlement, tracking, surveillance, customer inquiry and reporting among others activities. This means that more I/Os are generated with data to be moved, processed, replicated, backed-up with additional downstream activity and processing.

Shifting gears, same things with telephone and in particular cell phone traffic which indirectly relates on IT systems particular for support email and other messaging activity. Speaking of email, more and more emails are sent every day, granted many are spam, yet these all result in more activity as well as data.

What’s the point in all of this?

There is a common awareness among most IT professionals that there is more data generated and stored every year and that there is also an awareness of the increased threats and reliance upon data and information. However what’s either not as widely discussed is the increase in I/O and networking activity. That is, the space capacity often gets talked about, however, the I/O performance, response time, activity and data movement can be forgotten about or its importance to productivity diminished. So the point is, keep performance, response time, and latency in focus as well as IOPS and bandwidth when looking at, and planning IT infrastructure to avoid data center bottlenecks.

Finally for now, what’s your take, is there a data and/or I/O networking recession, or is it business and activity as usual?

Ok, nuff said.

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.

Do you have your copy of “The Green and Virtual Data Center” yet?

For those not familar with my new book, "The Green and Virtual Data Center" (Auerbach), or, for those who have already ordered your copy (Thank You and look for them to arrive soon) as today marks the offical publication date, or, I guess you could say the birthday for "The Green and Virtual Data Center".

Thus, I am pleased to share with you the news about the formal launch and publication (read the press release) of my new book, “The Green and Virtual Data Center”, which is released today by Auerbach/CRC-Press and is available at Amazon, Barnes & Noble, Borders, CRC-Press and other venues around the world.

The book focuses on the idea that IT infrastructure resources configured and deployed in a highly virtualized manner can be combined with other techniques and technologies to achieve a simplified and cost-effective delivery of IT services in a clean, green, and profitable manner. ?The Green and Virtual Data Center? covers these technologies and techniques that todays data centers should be considering while trying to maximize resources, such as power, cooling, floor space, storage, server performance, and network capacity.

Some of the topics include:
• Energy and data footprint reductions
• Cloud-based storage and computing
• Intelligent and adaptive power management
• Server, storage, and networking virtualization
• Tiered servers for storage, network, and data centers
• Energy avoidance and energy efficiency

It feels like Grand Central Station here…

Things have been busy (which is very good) and I feel like I’m at Grand Central station (Terminal) with the new year off to a flurry of activity ranging from my regular consulting, research and client advisory engagement projects, recent speaking appearances (San Jose and Tucson ), doing interviews with the media as well as vendor briefings.

Grand Central Station New York City - December 2008

Green Power and Cooling Tools and Calculators

In the course of doing research and consulting work with various IT organizations, VARs, trade groups and vendors over the past couple of years, not to mention in preparing for my new book "The Green and Virtual Data Center" (Auerbach), I have come across (see a list here) several tools, calculators and modeling or sizing utilities pertaining to power, cooling, floor-space, EH&S (PCFE) also known as green topics.

Many vendors and organizations including APC, Dell, EMC, Emerson, IBM, HP and Sun among others have various types of green and related calculators in support of PCFE, performance and related sizing activities. These and other tools differ in what information they provide as well as the level of detail and configuration information, however, the tools are also evolving. As an example, EMC blogger Mark Twomey aka Storagezilla has a new post discussing an updated version of their updated calculator that is now web based tool for PCFE and green sizing.

Remember The Alamo

Yesterday I made a quick trip down to San Antonio Texas (SAT) to do a keynote talk about "BC/DR and Virtual Environments" along with a sprinkling of IT effieincy aka Green; consolidation, power, cooling, footprint, data management and cloud topics mixed in the discussion. The dinner event was put on by TechTarget with the local host being Mobius (not to be confused with Moby, the artist). Mobius is a Texas value added reseller (VAR) and the event took place at Morton’s near the river walk in downtown SAT. This was my second trip to SAT in about two months have done a morning seminar talk about the "Wide World of Archiving – Life beyond Compliance" back in October, also downtown SAT.

It was a great event with a lively and interesting audience who provide good feedback and conversation sharing their experiences, concerns, issues and what they are looking at or for.

Some general take away’s that I have from talking with the IT folks who were in attendance at the event include:

Do you homework and due diligence with regard to using VCBs for VMware backups

Pay attenion to the details when re-architecting and updating data protection for virtual environments

iSCSI and FC as well as FCoE all have different roles and places now and into the future for virtual environments

Concern about clouds, they are interesting, are a tiered resource to compliment other resources

Cloud services need to be part of BC/DR including in plans to isolate against disruptions such what occurred with Amazon and others

Not all servers can be consolidated due to different reasons and issues

Virtualization platforms (software and appliance or storage system based) can be used for replication, migration and consolidation

Virtual tape libraries are being adopted while tape usage continues

Discussion around different tiers of storage, tiered access (e.g. iSCSI, FC, FCoE, IBA, NAS, etc) and tiered data protection

A common theme is doing more with less, maintaining service levels and support business growth

Now on a different note, from technology and trends to travel.

If you travel enough for business like I have had, you know that its not all jet set lifestyle like people think or assume, in fact many times what I get to see of a city or venue is the view from window of a car or train on the way from an airport to a venue, a hotel and sometimes a dinner event. However now and then, even on quick trips like yesterdays where I was in SAT for 15 hours, opportunities exist to get out even if its for just a moment and take in a site or two, see some of the city or area. Last night was an example of getting a chance to see something interesting when I walked the 7-8 blocks from the venue (I had gone directly from the airport to Mortons).

Walking back to my hotel (it was a nice evening for a walk) last night, I walked around and near the river walk and low and behold, I stopped, turned and looked and there it was, the Alamo (see photo below taken from my cell phone) in all its splendor. It actually looks a lot smaller than what I thought it would look like, however it was fun to do some inadvertent site seeing before an early morning flight home.

Remember the Alamo via Greg’s Cell Phone Camera 12/10/08

Now lets put travel into perspective here a bit.

When I woke up yesterday morning it was 3F at home in Stillwater, by time I got to the airport it was a balmy 9F, by mid afternoon when I arrived in SAT and stood in the taxi line, it was a down right tropical in the mid 50s F. This morning when I woke up around 5:30AM for my early morning flight home, it was a cool 35F in SAT with a forecast of getting back up into the 50s (F) today while it was a pleasant 13F when I arrived back at my office early afternoon, the fun of traveling!

Thanks to everyone who came out to last nights event and it was great to have had a chance to meet and visit with you, hopefully next time we will have more time for follow-up questions, however feel free to drop me a note. Also thanks too the Techtarget, Mobius and Mortons folks for putting a great event together, and, remember the Alamo and if you have not been there, check it and the river walk out!

Downloads for fall 2008 San Francisco Storage Decisions now available

The TechTarget Storage Media Group has posted on Bitpipe the session presentations from the recent fall (November 17-19th) 2008 San Francisco Storage Decisions event. If you have never been to a Storage Decisions event, it?s a great venue for meeting with IT and storage professionals as well as vendors who also show up to show their wares and meet with the attendees. Make no mistake about it, Storage Decisions is not a vendor to vendor meet and industry network event like SNW or a vendor sponsored user group like VMworld or EMCworld, rather, its focused on the IT and storage professional and encourages speakers to be frank and candid in their discussions of technologies, techniques and even of vendors and their solutions.

In addition to doing a keynote session Wednesday evening November 19th on ?Hot Storage Topics for Channel Professionals? at the Storage Strategies for Channel Professionals Dinner event, I also did two presentations at Storage Decisions one in the management and executive track Management and Executive Track on Green and Efficient Storage , an (updated version from what was covered in September 2008 at New York) timely theme given my new book ?The Green and Virtual Data Center? (Auerbach) along with another session in the Storage and capacity management track of ?Clustered and Grid Storage — From SMB, to Scientific, to Social Networking and Web 2.0? (also updated from September 2008)

View the entire list of all Storage Decisions sessions here.

A big thanks to all who came out last week in San Francisco at Storage Decisions and who attended the sessions enabling great discussion and insight both during the sessions, as well as during lunches, breaks and exhibition hours.

Time In and Around Clouds

This past week I spent some time in, around and above the clouds literally and figutively. I was in the Netherlands the past few days doing a seminar with Brouwer Storage as well as key note presentation on Wednesday at the Dutch StorageExpo in Utrecht (a fabulous event with lots of buzz and activity, nice job Marloes!) before flying home today from my favorite airport (Amsterdam Schiphol).

(Following photo’s were taken this past summer on an early morning flight from my phone camera)

Low visibility as you can barely see the wingtip

In addition to flying above the clouds over the Atlantic (not the above photos), the fall clouds at home where it was snowing when I left and then raining when I returned, with wind and clouds (some occasional sun) while in Holland, and then the industry buzz around EMC’s cloud and clustered storage solution announcement (also here and here and here and here) called Atmos (aka the solution code named hulk and maui), this week had a strong cloud theme along with a dose of policy management.

Meeting regularly with IT professionals from organizations of all size as well as various vendors and vars around the world, is a great way to avoid having your thinking end up to much in the clouds, instead, staying rooted as to where IT issues and pain points are vs. where they are perceived to be.

However, the long plane ride with no cell phone or email or web access also made for some great time to relax and watch the clouds go by. In a few days I?m back in the air again as next week I will be in San Francisco presenting at Storage Decisions. Next weeks topics will include a session updated with new content looking at “Clustered Storage: From SMB, to Scientific, to File Serving, to Commercial, Social Networking and Web 2.0” and grids among other topics.

If you are in the area, stop by and say hello next Monday and Tuesday at the San Francisco Hilton.

Ok, nuff said.

SSD activity continues to go virtually round and round

Storage I/O trends

Solid State Disk (SSD) (both FLASH and RAM based) activities and discussions continue to go round and round (pun intended) with announcements (here, here, here, here, here, and here and among others) of various improvements and evolution for technologies focused from the consumer to the small office home office (SOHO) to small medium business (SMB) to enterprise with technologies from vendors including Intel, Sandisk, Seagate and many others.

Recent innovations are looking to address write performance issues or challenges associated with FLASH based SSD, which while better than magnetic hard disk drives (HDD), are slower than their RAM based counterparts.

Other activity includes extending the useful life or duration of how many times a FLASH based device can be rewritten or modified before problems arise or performance degrades. Yet another activity is Sandisk introducing “virtual RPM” (vRPM) metrics to provide consumers an indication of relative revolutions per minute (RPM) of a non-rotating SSD device to make comparisons to help with shopping decisions makings. Can you say SSDs going round and round and round at least in a virtual world? Now that should make for some interesting “virtual benchmarking” discussions!

Meanwhile industry trade groups include the SNIA Solid State Storage Initiative (SSSI) are gathering momentum to address marketing, messaging, awareness, education as well as metrics or benchmarks among things normally done around industry trade group camp fires and camp outs.

So, as the HDDs spin, so to does the activity in and around SSD based technologies.

Ok, nuff said.

HP Storage Virtualization Services Platform (SVSP)

Storage I/O trends

HP recently announced announced their new SAN Virtualization Services Platform (SVSP) which is an appliance with software (oh, excuse me, I mean platform) for enabling various (e.g. replication, snapshots, pooling, consolidation, migration, etc) storage virtualization capabilities across different HP (e.g. MSA, EVA and in "theory" XP) or in "theory" as well, 3rd party (e.g. EMC, Dell, HDS, IBM, NetApp, Sun, etc) storage.

Sure HP has had a similar capability via their XP series which HP OEMs from Hitachi Ltd. (who also supplies the similar/same product to HDS which HP competes with), however what?s different from the XP based solution and the SVSP is that one (SVSP) is via software running on an appliance and the other implemented via software/firmware on dedicated Hitachi based hardware (e.g. the XP). One requires an investment in the XP which for larger organizations may be practical while the other enables smaller organizations to achieve the benefits of virtualization capabilties to enable efficient IT not to mention help transition from different generations of HP MSA, EVAs to newer versions of MSAs and EVAs or even to XPs .Other benefits of solutions like the HP SVSP which also include the IBM SAN Volume Controller (SVC) include cross storage system, or cross storage vendor based replication, snapshots, dynamic (e.g. thin) provisioning among other capabilities for block based storage access.

While there will be comparisons of HP SVSP to the XP, those in many ways will be apples to oranges, the more applicable apples to apples comparison would be IBM SVC to HP SVSP, or, perhaps HP SVSP to EMC Invista, Fujitsu VS900, Incipient, Falconstor or ?Datacore based solutions.

With the HP SVSP announcement, I’m suspecting that we will see the re-emergence of the storage virtualization in-band vs. out-of-band including fast-path control-path aka split path approaches being adopted by HP with the SVSP not to mention hardware vs. software and appliance based approaches as was the case a few years ago.

This time around as the storage virtualization discussions heat up again, we should see and hear the usual points, counter points and continued talk around consolidation and driving up utilization to save money and avoid costs. However, as part of enabling and transforming into an efficient IT organization (e.g. a ?Green and Virtual Data Center?) that embodies efficient, productivity in an economical and environmental friendly manner, virtualization discussions will also re-focus on using management transparency to enable data movement or migration for load-balancing, maintenance, upgrades and technology replacement, BC/DR and other common functions to enable more work to be done in the same or less anoint of time while supporting more data and storage processing and retention needs.

Thus similar to servers where not all servers have been, will be or can be consolidated, however most can be virtualized for management transparency for BC/DR and migration, the same holds true for storage, that is, not all storage can be consolidated for different quality of service reasons, however, most storage can be virtualized to assist with and facilatate common management functions.

IT Belt Tightening and Stratigies for IT Economic Sustainment

Storage I/O trends

There’s been and will continue to be lots of talk around tightening IT budgets and spending. Here’s a link to a piece by Chris Preimesberger over at eWeek titled “How the ‘Down’ Macroeconomy Will Impact the Data Storage Sector”.

Here’s another related piece by Marty Foltyn over on Internet News that looks at “Storage Technologies for a Slowing Economy”.

A macro trend that Im seeing and hearing more often is that with the demise or should I say, falling out of favor of Green hype and Green washing, there is a growing realization of the practical aspects of boosting efficiency and productivity with a by-product of being environmental friendly while addressing economic issues.

The so called Green Gap (See here, here, here, here, and here) exists between green hype and rhetoric which is now destined for the endangered species or extinction list, while core issues including power, cooling, floor space/footprint and environmental health & safety (EH&S) known as PCFE that need to be addressed are in fact covered under the broader green umbrella.

With the growing realization that efficiency gains that can boost IT productivity to sustain and enable business and economic growth also help the environment, there is awareness that those initiatives and activities that address PCFE and related issues are in fact green and part of many organizations agendas and budgets. Consequently going green for the sake of going green may be falling out of favor or off of budgets for many, addressing PCFE related issues to sustain business and economic growth are gaining in popularity though not always associated with as being green.

Thus in tough economic times where dollars and productivity become important, the new green will be that of efficiency and productivity with a by-product benefit being to help the environment, some of the themes in my book, The Green and Virtual Data Center (Auerbach) that you can pre-order now at Amazon.com and other venues around the world.

Ok, nuff said.

Storage Performance Council releases Component (SPC-1C and SPC-2C) results

Storage I/O trends

For those interested in benchmarking activities or debates, the Storage Performance Council (aka SPC) released their new component level tests along with some first results for disk drives.

What differs the component SPC tests (e.g. SPC-1C and SPC-2C) from their the total system tests (SPC-1C and SPC-2C) is that only specific components are tested, such as a disk drive or adapter without being part of a total solution. If you recall from back in January of this year, NetApp stirred things up a bit by submitting SPC results for themselves as well as for EMC.

Here’s a link to a presentation from SPC about SPC-1C and SPC-2C.

In addition to the SPC-1C and SPC-2C, there are also several new SPC-1 and SPC-2 submissions from a long list of vendors and their latest technologies including with more in the works.

Cheers
