Happy Earth Day 2009

Its that time of the year again, that’s right, earth day April 22 2009!

If you frequent this blog, visit my websites (StorageIO, The Green and Virtual Data Center or Green Data Storage), track twitter, attended any of my speaking engagements, webcast, podcast, videos, radio interviews, seen press or media coverage, not to mention read any of my reports, articles, tips or books, it should not come as a surprise that I have something to say about Green IT and closing the Green Gap.

The Green and Virtual Data Center (CRC)

Common themes have included awareness of the green gap and how to address or close it including discussions around IT transformation, infrastructure optimization, boosting productivity and efficiency to support business sustainability among others. While its tempting to go on and on about different trends, topics, techniques, technologies and related themes with a back drop of earth day, lets leave it at this for now in the sake of brevity and efficiency.

There’s plenty of existing content to be recycled and reused or seen and viewed for today including at some of the above links. However, rest assured, there is more content in the works pertaining to enabling Green IT with a focus around data center productivity, efficiency and sustainability, doing more with less, or, doing more with what is available.

So happy earth day 2009, chat with you again soon.

Ok, nuff said.

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.

MSP Business Journal Names Greg Schulz an Eco-tech Warrior

In the April 10th, 2009 issue of the Minneapolis St. Paul (MSP) Business Journal, guess who was named one of three Eco-Tech Warriors? That’s right, yours truly (See the article here).

Photo by Nancy Kuehn – MSP Business Journal

What can I say, I’m flattered and appreciate the coverage. Besides seeing the finished article in the special report, the real fun was doing the photo shoot with the props including the heavy swords, those were not plastic (Hummm, Iron Chef?)!

The photo shoot with the other two “Eco-Warriors” Tom Diamond of New Boundary Technology, and Travis Pakonen of Encompass Solutions along with Nancy Kuehn our photographer as well as the artistic and project management folks from MSP Business Journal were an absolute blast to work with.

For those of you looking for policy management as well as energy management tools for desktops, workstations and PCs, checkout Tom Diamonds New Boundary Technologies and their solutions. Likewise, I hear good things from friends who have used the services of Travis Pakonen and N’Compass for their data center projects.

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.

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

    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).

    Learn more about the above and other related topics at the StorageIO In the news, tips, events and Industry Trends White Paper as well as Books and Blog pages.

    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.

    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.

    Shifting Industry Trend, from Purchase to Leasing?

    Storage I/O trends

    I’m seeing and hearing a trend talking with vendors, vars and customers of what appears to be a shifting trend from purchasing to leasing of IT equipment which for some might be as surprising as saying that the sun rises in the east and sets in the west. Typically, or at least looking back in time, leases tend to be popular when cash is at a premium or during rapid growth phases such as during the dot com craze bubble of last decade.

    Purchasing tends to be more popular when lease rates are high or when cash reserves are enough to take advantage of buy opportunities Consequently with tight credit and focus by many organizations on cash flow and cash reserves, it should not be as much of a surprise to see a shift to leasing. However what’s a bit different from earlier economic downturns when IT organizations typically shift from purchase to lease, is the tight credit markets or ability of some organizations to finance acquisitions. Consequently it will be interesting to see if there is a shifting trend from purchasing to lease particularly as the credit markets begin to open.

    What are you seeing or doing, purchasing, leasing, out-sourcing or shifting to managed service providers or doing nothing?

    Ok, nuff said.
