Last week, fellow IBMer Ron Riffe started his three-part series on the Storage Hypervisor. I discussed Part I already in my previous post [Storage Hypervisor Integration with VMware]. We wrapped up the week with a Live Chat with over 30 IT managers, industry analysts, independent bloggers, and IBM storage experts.
This week, Ron continues this meme with his post [Enabling Private IT for Storage Cloud -- Part II (management controls)]. Here's an excerpt:
A storage hypervisor increases the utilization of storage resources, and optimizes what is most scarce in your environment. For Linux, UNIX and Windows servers, you typically see utilization rates of 20 to 35 percent, and this can be raised to 55 to 80 percent with a storage hypervisor. But what is most scarce in your environment? Time! In a competitive world, it is not big animals eating smaller ones as much as fast ones eating the slow.
If this sounds all too familiar, it is similar to the benefits that one gets from a server hypervisor -- better utilization of CPU resources, optimizing the management and administration time, with the agility and flexibility to deploy new technologies in and decommission older ones out.
Arthur Cole disagrees. His blog post asks [

Jon Toigo on his DrunkenData blog brings back the sanity with his post [Once More Into the Fray]. Here is an excerpt:
Did you miss out on last Friday's Live Chat? We are doing it again this Friday, covering parts I and II of Ron's posts, so please join the conversation! The virtual dialogue on this topic will continue in another [Live Chat] on September 30, 2011 from 12 noon to 1pm Eastern Time.

Can you believe it has been five years since I started blogging?
(If you absolutely abhor the navel-gazing associated with blog
Back in July 2005, IBM decided to merge together two brands, IBM eServer and IBM TotalStorage, into a single all-encompassing "IBM Systems" brand. Thus TotalStorage brand became the "IBM System Storage" product line of the "IBM Systems" brand. The next six months was spent renaming some (not all) of the products. The following January, I was named the Marketing Strategist for this new product line, with the mission to help promote the new naming convention.
We looked at possibly doing a regularly-scheduled podcast, but nobody back then, including myself, were familar with audio editing tools. Instead, we chose a blog. Most blogs at IBM are internal, safely hidden behind the firewall, accessible only to IBM employees. I wanted mine to be different, to be accessible to the public, clients, prospects, IBM Business Partners, and yes, even those working for IBM's various competitors. One thing I like about blogs is that if you have a typo, or make a mistake, you can go back and correct it after it has posted.
Marketing through social media is quite different than traditional marketing techniques. Management was supportive, but legal wanted to review and approval everything I wrote before I posted it onto my blog. Official IBM Press Releases, for example, go through a dozen reviews before they are finally made public. I refused. This kind of review and approval would ruin the blogging process.
Fortunately, this blog was not my first attempt at technical writing. Our legal counsel reviewed my past trip reports from various conferences, and decided to let me blog without review. Occasionally, someone will reivew my blog once already posted, and ask me to make some corrections. It reminds me of my favorite saying used heavily within IBM:
It is easier to get forgiveness than permission.
Despite these delays, we managed to launch this blog in September 2006, just in time to celebrate the 50th anniversary of disk systems. IBM introduced the industry's first commercial disk system on September 13, 1956.
Over the years, this blog has helped sales reps and IBM Business Partners close deals, and address the FUD their prospects heard from competition. I have helped my readers get in touch with the right people within IBM. And, I have "sent the elevator back down", helping other IBMers launch their own blogs, including [Barry Whyte], [Elisabeth Stahl], and [Anthony Vandewerdt].
Today, bloggers have a profound impact on the world. Not everyone has a positive view on this. Bloggers and other users of social media have been seen as whistle-blowers for fraudulent corporations, as activists against corrupt governments and dictators, and as subject matter experts and fact checkers referenced during television and radio newscasts. In a recent movie, one of the major characters was a trouble-making blogger, and another character describes his blogging as nothing more than "graffiti with punctuation."
I want to thank all of my readers for making this the #1 most influential blog on IBM DeveloperWorks in 2011! This blog has been [published in a series of books], Inside System Storage Volume I and Volume II. And yes, before you all ask in the comments below, I am actively working on Volume III.
For a bit of nostalgia, I invite you to read my first 21 blog posts that I posted back in [September 2006].
Every September, IBM Tucson spends a Wednesday or Saturday to help out local non-profit charities. The event is orgnaized the the local United Way. My first one was packing boxes of food for the [Community Food Bank of Southern Arizona] on September 12, 2001, the day after the [tragic events in New York and Washington DC]. The mindless activity of putting a bottle, bag or can into one box after another helped us cope with the shock and awe that week.
So, it seemed fitting on the 10th anniversary of that event to go back to the Community Food Bank and help pack boxes of food. The facility received nearly $200,000 in donations in response to the [shooting of US Congresswoman Gabrielle Giffords]. Her husband, astronaut Mark Kelly, suggested that dontaions go in part to the Tucson Community Food Bank, and with the money they were able to expand operations, dedicating a portion as the [Gabrielle Giffords Family Assistance Center] to bring together food handouts with the [Supplemental Nutrition Assistance Program for food stamps, and the Women with Infant Children (WIC) program. One-stop assistance!
This year, nearly 500 Tucson IBMers to complete 22 projects at 17 nonprofit agencies. We were not alone, we were joined by volunteers from Bank of America, Texas Instruments, Tucson Medical Center, Geico Insurance, University of Arizona, Cox Cable TV, Desert Diamond Casinos, The Westin La Paloma Resort and Spa, the Arizona Lottery, Community Partnership of Southern Arizona (CPSA), Pizza Hut, Arizona Daily Star, 94.9 MixFM Radio, BizTucson, and News 4 Tucson (our local NBC affiliate).
In a bit of competition, our team, Team B, of 14 IBMers, competed against another team, Team A, of 20 people. Despite having fewer people, we were able to pack 746 boxes, representing 20,000 pounds of food, beating out Team A which only packed 18,000 pounds. (I have chosen not to identify anyone on Team A, no need to rub their noses in it. This was all for a good cause.)
Each box contained cereal, canned evaporated milk, canned vegetables and fruits, fruit juice, rice, and dry beans. My job on the assembly line was to put two half-gallon jugs of grape juice in the box and move it down the line.
What lessons can a team of people learn from an activity like this?
This was a great day for a good cause. The Community Food Bank qualifies for the Arizona [Working Poor Tax Credit] program. For every dollar the Community Food Bank receives, they can give 10 dollars of food to someone in need.
Special thanks to Greg Kishi for being our team leader for this event, and to Carol Tribble for taking these photographs.
Over on the Tivoli Storage Blog, there is an exchange over the concept of a "Storage Hypervisor". This started with fellow IBMer Ron Riffe's blog post [Enabling Private IT for Storage Cloud -- Part I], with a promise to provide parts 2 and 3 in the next few weeks. Here's an excerpt:
Then another IBM blogger, Richard Vining, continued this meme with his post [VMware Data Protection with a Storage Hypervisor]. There are [different meanings for the word "protect"], but Richard's usage relates to protecting against unexpected loss. Here's an excerpt:
At this point, you might scratch your head and ask "Does this Storage Hypervisor exist, or is this just a theoretical exercise?" The answer of course is "Yes, it does exist!" Just like VMware offers vSphere and vCenter, IBM offers block-level disk virtualization through the SAN Volume Controller(SVC) and Storwize V7000 products, with a full management support from Tivoli Storage Productivity Center Standard Edition.
SVC has supported every release of VMware since the 2.5 version. IBM is the leading reseller of VMware, so it makes sense for IBM and VMware development to collaborate and make sure all the products run smoothly together. SVC presents volumes that can be formatted for VMFS file system to hold your VMDK files, accessible via FCP protocol. IBM and VMware have some key synergies:
But unlike tools that work only with VMware, IBM's storage hypervisor works with a variety of server virtualization technologies, including Microsoft Hyper-V, Xen, OracleVM, Linux KVM, PowerVM, z/VM and PR/SM. This is important, as a recent poll on the Hot Aisle blog indicates that [44 percent run 2 or more server hypervisors]!
For a set of best practices combining VMware with SVC, check out this IBM Redpaper titled [VMware Proof of Practice and Performance Guidelines on the SAN Volume Controller].
Join the conversation! The virtual dialogue on this topic will continue in a [live group chat] this Friday, September 23, 2011 from 12 noon to 1pm EDT. Join me and about 20 other top storage bloggers, key industry analysts and IBM Storage subject matter experts to discuss storage hypervisors and get questions answered about improving your private storage environment.

Last February, IBM introduced Watson on the Jeopardy! game show. These three shows were re-aired this week in the United States. I wrote a series of blog posts back then:
This last one on how to build your own Watson, Jr. has gotten over 69,000 hits! While several people told me they plan to build their own, I have not heard back from anyone yet, so perhaps it is taking longer than expected.
IBM and Wellpoint announced this week that it will be [putting Watson to work] in healthcare. [Wellpoint] is one of the largest health benefits company in the United States, with over 70 million people served through its affiliate plans and its various subsidiaries. I am one of the development lab advocates for Wellpoint, and have been proud to work with the account team to help Wellpoint achieve their goals.
This marks the first commercial deployment of IBM Watson. This is a joint effort. IBM will develop the base IBM Watson for healthcare platform, and Wellpoint will then develop healthcare-specific solutions to run on this platform. Watson's ability to analyze the meaning and context of human language, and quickly process vast amounts of information to suggest options targeted to a patient's circumstances, can assist decision makers, such as physicians and nurses, in identifying the most likely diagnosis and treatment options for their patients.
Is this going to put doctors out of business? No. Physicians find it challenging to read and understand hundreds or thousands of pages of text, and put this into their practice. IBM Watson, on the other hand, can scan through hundred of millions of pages in just a few seconds to help answer a question or provide recommendations. Together, doctors armed with access to IBM Watson will be able to improve the quality and effectiveness of medical care.
From an insurance point of view, improving the quality of care will help reduce medical mistakes and malpractice lawsuits. This is a win-win for everyone except ambulance-chasing lawyers!
Last week, US President Barack Obama declared September 2011 as "National Preparedness Month". Here is an excerpt of the press release:
IBM has several webinars to help you prepare for upcoming disasters.
Today, September 8, at 4pm EDT, IBM is hosting a [CloudChat on Business Resilience] will focus on resiliency and continuity in the cloud—a timely topic considering the recent weather events on the East Coast of the U.S. This chat will include Richard Cocchiara, IBM Distinguished Engineer and CTO, IBM Business Continuity and Resiliency Services (@RichCocchiara1) and Patrick Corcoran, Global Business Development, IBM Business Continuity and Resiliency Services (@PatCorcoranIBM).
Don't think you can afford Disaster Recovery planning? Next week, September 13, I will be joined with a few other experts on freeing up much needed funds from your tight IT budget, by being more efficient. The Webinar [Taming Data Growth Made Easy] is part of IBM's "IT Budget Killer" series.
Lastly, on September 21, IBM will have the Webinar [Planning for Disaster Recovery in a Power Environment: Best Practices to Protect Your Data]. This will cover principal lessons learned from disasters like Hurricane Katrina and the World Trade Center, local and regional considerations for Disaster Recovery Planning, planning Recovery Time Objectives (RTOs), and best practices for automation, mirroring and multiple Site Operational Efficiencies. A customer case study from University of Rochester Medical Center (URMC) will help reinforce the concepts, with a discussion on how a major hospital ensures Business Continuity via Contingency Planning using IBM Power Systems. The speakers in clude Steve Finnes, World Wide Offering Manager for IBM Power Systems, Vic Peltz, Consulting IT Architect for WW Business Continuance Technical Marketing, and Rick Haverty, Director of IT Infrastructure at University of Rochester Medical Center (URMC).
Hopefully, you will find these webinars useful and informative!
We had our first "Future of IT Storage" Lunch-and-Learn here in Indianapolis, IN. We held it at the [Harry & Izzy's Restaurant], which looks like it has been in business for quite a while, but actually was only started four years ago. It is the sister restaurant for St. Elmo's next door which has been running since 1902, so it maintains a sense of that heritage, but with a bit more casual atmosphere.
I presented [The Future of Storage] that I mentioned in my blog post [Infoboom Webinar]. If you missed it, you can check out the [presentation deck and replay]. We had a lively Q&A throughout the presentation, so I am happy about that.
Please note that in the wake of Hurricane Irene, the [Burlington, MA (Boston Area) event] has been postponed, probably to October or November. We have already notified all the people who signed up, but in case you planned just to show up, I wanted to let you know here in this blog.
Special thanks to Karen Harrison and Kerry Ingram for their help in setting up this event! Also a shout-out to Leanna and Amy, our two waitresses who served us today!
Wrapping up my coverage of the [IBM System Storage Technical University 2011], I attended a few sessions on Friday morning. The last session was Glenn Anderson's "IT Game Changers: the IT Professional's Guide to Becoming a Technology Trailblazer." Glenn used to run the Storage University events, but now is the conference manager for the System z mainframe events.
Glenn organized this talk from lessons from the following books:
Glen suggested that IT professionals should understand the dissatisfaction with IT that is driving companies to switch over to Cloud Computing. IT professionals should adopt a service-oriented approach, realize the full potential of new disruptive technologies, and know when to "jump the curve" to the next generation of technology. For example, IT professionals should lead the movement to Cloud. If you build your own private cloud, or purchase some time for instances on a public cloud, you will be in a better position to be the "trusted advisor" to IT management.
CIOs should encourage IT to be part of the corporate strategy, but may have to fix the broken IT funding model. The IT department should be a "value center" not a "cost center" as it has been traditionally treated. When treated as a "cost center", IT departments only focus on cost reductions, and not looking at ways that the IT department can help drive revenues, improve customer service, or enhance employee productivity. A well-orgnized IT department can be a competitive advantage.
Taking a "service-oriented" approach allows IT and Business Process to come together. Often times, IT and business professionals don't communicate well, and this new service-oriented approach can bridge the gap. Service Oriented Architecture [SOA] can help connect existing legacy applications to the new Cloud Computing environment.
IT budgets should consist of two parts. Strategic funding for new IT projects, and an operational budget for keeping current applications running. Roughly 45 percent of capital investment in USA goes toward IT. Too often, the IT department is focused on itself, on technology and reducing costs, and not enough on aligning IT with business transformation. When IT is used in conjunction with a sound business strategy, their can be significant payoff.
After 550 years, the printing press and printed materials are being pushed from center. While other electronic media like radio and television have been around for a while, the internet and digital publishing are constantly available, and represent a shift from traditional printed materials.
When evaluating new technologies, IT professionals should ask themselves a few questions. Is it easy to use? Does it enable people to connect in new ways? Is it more cost-effective, or tap new sources of revenue? Does it shift power from one player to another? A new intellectual ethic is taking hold. Becoming an IT Game Changer can help stay one step ahead as Cloud Computing and other new IT platforms are adopted.
Continuing my coverage of the [IBM System Storage Technical University 2011], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This year, we had two, one for System x called "Ask the eXperts", and one for System Storage called "Storage Free-for-All". This post covers the latter.
(Disclaimer: Do not shoot the messenger! We had a dozen or more experts on the panel, representing System Storage hardware, Tivoli Storage software, and Storage services. I took notes, trying to capture the essence of the questions, and the answers given by the various IBM experts. I have spelled out acronyms and provided links to relevant materials. The answers from individual IBMers may not reflect the official position of IBM management. Where appropriate, my own commentary will be in italics.)Are there any plans to improve the use of BRMS [Backup Recovery and Media Services for IBM i] with [Tivoli Storage Manager (TSM)]?
It should be against the law to connect these two together. IBM has no plans to make any further improvements.When will [IBM BladeCenter S] support 2.5-inch drives?
You are in the wrong session! Go to "Ask the eXperts" session next door!The TSM GUI sucks! Are there any plans to improve it?
Yes, we are aware that products like IBM XIV have raised the bar for what people expect from graphical user interfaces. We have plans to improve the TSM GUI. IBM's new GUI for the SAN Volume Controller and Storwize V7000 has been well-received, and will be used as a template for the GUIs of other storage hardware and software products. The GUI uses the latest HTML5, Dojo widgets and AJAX technologies, eliminating Java dependencies on the client browser.Can we run the TSM Admin GUI from a non-Windows host?
IBM has plans to offer this. Most likely, this will be browser-based, so that any OS with a modern browser can be used.As hard disk drives grow larger in capacity, RAID-5 becomes less viable. What is IBM doing to address this?
IBM is aware of this problem. IBM offers RAID-DP on the IBM N series, RAID-X on the IBM XIV, and RAID-6 on its other disk systems.TPC licensing is outrageous! What is IBM going to do about it?
IBM introduced the [Tivoli Storage Productivity Center for Disk Midrange Edition (MRE)] to help address the cost when Small and Medium-sized Businesses managing SVC, Storwize V7000, DS5000 and DS3000 disk systems.What is the adoption rate of IBM Easy Tier?
About 25 percent of DS8000 disk systems have SSD installed. Now that IBM DS8000 Easy Tier supports "any two" tiers, roughly 50 percent of DS8000 now have Easy Tier activated. No idea on how Easy Tier has been adopted on SVC or Storwize V7000.We have an 8-node SVC cluster, should we put 8 SSD drives into a single node-pair, or spread them out?
We recommend putting a separate Solid-State Drive in each SVC node, with RAID-1 between nodes of a node-pair. By separating the SSD across I/O groups, you can reduce node-to-node traffic.How well has SVC 6.2 been adopted?
The inventory call-home data is not yet available. The only SVC hardware model that does not support this level of software was the 2145-4F2 introduced in 2003. Every other model since then can be updated to this level.Will IBM offer 600GB FDE drives for the IBM DS8700?
Currently, IBM offers 300GB and 450GB 15K RPM drives with the Full-Disk Encryption (FDE) capability for the DS8700, and 450GB and 600GB 10K RPM drives with FDE for the IBM DS8800. IBM is working with its disk suppliers to offer FDE on other disk capacities, and on SSD and NL-SAS drives as well, so that all can be used with IBM Easy Tier.Is there a reason for the feature lag between the Easy Tier capabilities of the DS8000, and that of the SVC/Storwize V7000?
We have one team for Easy Tier, so they implement it first on DS8000, then port it over to SVC/Storwize V7000.Does it even make sense to have separate storage tiers, especially when you factor in the cost of SVC and TPC to make it manageable?
It depends! We understand this is a trade-off between cost and complexity. Most data centers have three or more storage tiers already, so products like SVC can help simplify interoperability.Are there best practices for combining SVC with DS8000? Can we share one DS8000 system across two or more SVC clusters?
Yes, you can share one DS8000 across multiple SVC clusters. DS8000 has auto-restripe, so consider having two big extent pools. The queue depth is 3 to 60, so aim to have up to 60 managed disks on your DS8000 assigned to SVC. The more managed disks the better.The IBM System Storage Interopability Center (SSIC) site does not seem to be designed well for SAN Volume Controller.
Yes, we are aware of that. It was designed based on traditional Hardware Compatability Lists (HCL), but storage virtualization presents unique challenges.How does the 24-hour learning period work for IBM Easy Tier? We have batch processing that runs from 2am to 8am on Sundays.
You can have Easy Tier monitor across this batch job window, and turn Easy Tier management between tiers on and off as needed.Now that NetApp has acquired LSI, is the DS3000 still viable?
Yes, IBM has a strong OEM relationship with both NetApp and LSI, and this continues after the acquisition.If have managed disks from a DS8000 multi-rank extent pool assigned to multiple SVC clusters, won't this affect performance?
Yes, possibly. Keep managed disks on seperate extent pools if this is a big concern. A PERL script is available to re-balance SVC striped volumes as needed after these changes.Is the IBM [TPC Reporter] a replacement for IBM Tivoli Storage Productivity Center?
No, it is software, available at no additional charge, that provides additional reporting to those who have already licensed Tivoli Storage Productivity Center 4.1 and above. It will be updated as needed when new versions of Productivity Center are released.We are experiencing lots of stability issues with SDD, SDD-PCM and SDD-DSM multipathing drivers. Are these getting the development attention they deserve?
IBM's direction is to shift toward native OS-based multipathing drivers.Is anyone actually thinking of deploying public cloud storage in the near-term?
A few hands in the audience were raised.None of the IBM storage devices seem to have [REST API]. Cloud storage providers are demanding this. What are IBM plans?
IBM plans to offer REST on SONAS. IBM uses SONAS internally for its own cloud storage offerings.If you ask a DB2 specialist, an AIX specialist, and a System Storage specialist, on how to configure System p and System Storage for optimal performance, you get three different answers. Are there any IBMers who are cross-functional that can help?
Yes, for example, Earl Jew is an IBM Field Technical Support Specialist (FTSS) for both System p and Storage, and can help you with that.Both Oracle and Microsoft recommend RAID-10 for their applications.
Don't listen to them. Feel free to use RAID-5, RAID-6 or RAID-X instead.Resizing SVC source volumes forces ongoing FlashCopy or Metro Mirror relatiohships to be stopped. Does IBM plan to address this?
Currently, you have to stop, resize both source and target, then start the relationship again. Consider getting IBM Tivoli Storage Productivity Center for Replication (TPC-R).What ever happened to IBM [Grid Medical Archive Solution (GMAS)]?
IBM continues to support this for exising clients. For new deployments, IBM offers SONAS and the Information Archive (IA).When will I be able to move SVC volumes between I/O groups?
You can today, but it is disruptive to the operating system. IBM is investigating making this less disruptive.Will XIV ever support the mainframe?
It does already, with support for both Linux and z/VM today. For VSE support, use SVC with XIV. For those with the new zBX extension, XIV storage can be used with all of the POWER and x86-based operating systems supported. IBM has no plans to offer direct FICON attachment for z/OS or z/TPF.Not a question - Kudos to the TSM and ProtecTIER team in supporting native IP-based replication!
Thanks!When will IBM offer POWER-based models of the XIV, SVC and other storage devices?
IBM's decision to use industry-standard x86 technology has proven quite successful. However, IBM re-looks at this decision every so many years. Once again, the last iteration determined that it was not worth doing. A POWER-based model might not beat the price/performance of current x86 models, and maintaining two separate code bases would hinder development of new innovations.We have both System i and System z, what is IBM doing to address the fact that PowerHA and GDPS are different?
IBM TPC-R has a service offering extension to support "IBM i" environments. GDPS plans to support multi-platform environments as well.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.
