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
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.

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.

Server Storage I/O Network Virtualization Whats Next?

Server Storage I/O Network Virtualization Whats Next?
Server Storage I/O Network Virtualization Whats Next?
Updated 9/28/18

There are many faces and thus functionalities of virtualization beyond the one most commonly discussed which is consolidation or aggregation. Other common forms of virtualization include emulation (which is part of enabling consolidation) which can be in the form of a virtual tape library for storage to bridge new disk technology to old software technology, processes, procedures and skill sets. Other forms of virtualization functionality for life beyond consolidation include abstraction for transparent movement of applications or operating systems on servers, or data on storage to support planned and un-planned maintenance, upgrades, BC/DR and other activities.

So the gist is that there are many forms of virtualization technologies and techniques for servers, storage and even I/O networks to address different issues including life beyond consolidation. However the next wave of consolidation could and should be that of reducing the number of logical images, or, the impact of the multiple operating systems and application images, along with their associated management costs.

This may be easier said than done, however, for those looking to cut costs even further than from what can be realized by reducing physical footprints (e.g. going from 10 to 1 or from 250 to 25 physical servers), there could be upside however it will come at a cost. The cost is like that of reducing data and storage footprint impacts with such as data management and archiving.

Savings can be realized by archiving and deleting data via data management however that is easier said than done given the cost in terms of people time and ability to decide what to archive, even for non-compliance data along with associated business rules and policies to be defined (for automation) along with hardware, software and services (managed services, consulting and/or cloud and SaaS).

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.

    The Alamo
    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!

    Data Migration Tips

    Storage I/O trends

    Data migration and movement, whether to support technology upgrades or replacements, tiered storage, ILM, consolidation, BC/DR and load balancing among other things is something that most if not all IT environments do at some point in time. Some organizations based on size or other criteria may be more involved with data migration on a more routine basis using host software, appliances or migration tools, storage system as well as migration services.

    Robert (Bob) Scheier has a new article over on SearchStorage about Eight data migration tips” that provides a good basis or starting point for learning more about issues, options and general items to consider with regard to data movement and migration. Read more what Robert and those he talks with including me in his new article here.

    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.

    Storage Optimization: Performance, Availability, Capacity, Effectiveness

    Storage I/O trends

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

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

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

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

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

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

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

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

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

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

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

    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.

    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.

    From ILM to IIM, Is this a solution sell looking for a problem?

    Storage I/O trends

    Enterprise Storage Forum has a new piece about what could be the successor to ILM from a marketing rallying cry perspective in the form of Intelligent Information Management (IIM).

    Information management is an important topic, however, given tough economic times, can IIM be joined into some other discussions about efficiency and boosting productivity to help justify its cost what ever that cost may be in terms of more hardware, software and people to carry out? With EMC and Gartner banging the drum, it will be interesting to see who else jumps on the IIM bandwagon.

    On the other hand, lets see what over variations surface perhaps an VIIM (Virtualized IIM), or a IIMaaS (IIM as a Service), or how about Cloud IIM or GIIM (Green IIM) among others like xIIM where you plug what ever letter you want in front if IIM (something that someone missed out on a few years ago by not grabbing xLM).

    While I see the importance of data management, the bottom line is going to be how to budget and build a business case when sustaining business growth in tough economic times is a common theme. Hopefully we can see some business case and justifications that can involve some self-funded, that is, the cost of adopting and deploying IIM is covered by the savings in associated hardware and software management and maintenance fees as well as a means of boosting overall IT and data management productivity.

    CMG, Enabling “The Green and Virtual Data Center”

    Storage I/O trends

    Last week I was invited to by Tom Becchetti and the Minneapolis CMG folks to keynote at their session hosted at the Brocade facity in Minneapolis along with other speakers from Brocade, IBM, Teamquest and Sun.

    The theme of my talk was “The Green and Virtual Data Center and The Importance of Metrics” which can be downloaded here.

    I have been a member of CMG for many years as a former performance and capacity planning analyst when I worked in IT organizations and having presented at many CMG events around the world. While CMG has been around for many decades and has seen its share of ups and downs. With a current focus on boosting use, maximizing resource usage, improving service delivery and performance while using less energy in smaller footprints, now is the perfect opportunity for CMG to re-invent itself and show relevance as the organization that knows how to measure, watch, model and manage resource usage and service delivery effectiveness across different technology domains including servers, storage, networks, applications, operating systems and facilities. There is a golden opportunity for CMG members to step up and leverage their skills across different technology domains working with others to establish metrics, models and baselines.

    In my new book, “The Green and Virtual Data Center” (Auerbach) I include a chapter on metrics and measurement as well as many other topics and themes that tie into the notion of effective and efficient data centers need to carry out Infrastructure Resource Management (IRM) which is also a chapter in the book, that includes performance and capacity planning across technology domains.

    Watch for more on this topic.

    Ok, nuff said.
