Fellow master inventor and blogger Barry Whyte (IBM) recounts the past 20 years of history in IT storage from his perspective in a series of blog posts. They are certainly worth a read:
In his last post in this series, he mentions that the amazingly successful IBM SAN Volume Controller was part of a set of projects:
"IBM was looking for "new horizon" projects to fund at the time, and three such projects were proposed and created the "Storage Software Group". Those three projects became know externally as TPC, (TotalStorage Productivity Center), SanFS (SAN File System - oh how this was just 5 years too early) and SVC (SAN Volume Controller). The fact that two out of the three of them still exist today is actually pretty good. All of these products came out of research, and its a sad state of affairs when research teams are measured against the percentage of the projects they work on, versus those that turn into revenue generating streams."
But this raises the question: Was SAN File System just five years too early?
IBM classifies products into three "horizons"; Horizon-1 for well-established mature products, Horizon-2 was for recently launched products, and Horizon-3 was for emerging business opportunities (EBO). Since I had some involvement with these other projects, I thought I would help fill out some of this history from my perspective.
Back in 2000, IBM executive [Linda Sanford] was in charge of IBM storage business and presented that IBM Research was working on the concept of "Storage Tank" which would hold Petabytes of data accessible to mainframes and distributed servers.
In 2001, I was the lead architect of DFSMS for the IBM z/OS operating system for mainframes, and was asked to be lead architect for the new "Horizon 3" project to be called IBM TotalStorage Productivity Center (TPC), which has since been renamed to IBM Tivoli Storage Productivity Center.
In 2002, I was asked to lead a team to port the "SANfs client" for SAN File System from Linux-x86 over to Linux on System z. How easy or difficult to port any code depends on how well it was written with the intent to be ported, and porting the "proof-of-concept" level code proved a bit too challenging for my team of relative new-hires. Once code written by research scientists is sufficiently complete to demonstrate proof of concept, it should be entirely discarded and written from scratch by professional software engineers that follow proper development and documentation procedures. We reminded management of this, and they decided not to make the necessary investment to add Linux on System z as a supported operating system for SAN file system.
In 2003, IBM launched Productivity Center, SAN File System and SAN Volume Controller. These would be lumped together with Horizon-1 product IBM Tivoli Storage Manager and the four products were promoted together as the inap
The SAN File System was the productized version of the "Storage Tank" research project. While the SAN Volume Controller used industry standard Fibre Channel Protocol (FCP) to allow support of a variety of operating system clients, the SAN File System required an installed "client" that was only available initially on AIX and Linux-x86. In keeping with the "open" concept, an "open source reference client" was made available so that the folks at Hewlett-Packard, Sun Microsystems and Microsoft could port this over to their respective HP-UX, Solaris and Windows operating systems. Not surprisingly, none were willing to voluntarily add yet another file system to their testing efforts.
Barry argues that SANfs was five years ahead of its time. SAN File System tried to bring policy-based management for information, which has been part of DFSMS for z/OS since the 1980s, over to distributed operating systems. The problem is that mainframe people who understand and appreciate the benefits of policy-based management already had it, and non-mainframe couldn't understand the benefits of something they have managed to survive without.
(Every time I see VMware presented as a new or clever idea, I have to remind people that this x86-based hypervisor basically implements the mainframe concept of server virtualization introduced by IBM in the 1970s. IBM is the leading reseller of VMware, and supports other server virtualization solutions including Linux KVM, Xen, Hyper-V and PowerVM.)
To address the various concerns about SAN File System, the proof-of-concept code from IBM Research was withdrawn from marketing, and new fresh code implementing these concepts were integrated into IBM's existing General Parallel File System (GPFS). This software would then be packaged with a server hardware cluster, exporting global file spaces with broad operating system reach. Initially offered as IBM Scale-out File Services (SoFS) service offering, this was later re-packaged as an appliance, the IBM Scale-Out Network Attached Storage (SONAS) product, and as IBM Smart Business Storage Cloud (SBSC) cloud storage offering. These now offer clustered NAS storage using the industry standard NFS and CIFS clients that nearly all operating systems already have.
Today, these former Horizon-1 products are now Horizon-2 and Horizon-3. They have evolved. Tivoli Storage Productivity Center, GPFS and SAN Volume Controller are all market leaders in their respective areas.

Here are some upcoming events related to IBM Storage!
If you sell IBM and/or Oracle solutions, please join me for IBM Oracle Virtual University 2013!
A few weeks ago, I recorded a session on IBM Storage: Overview, Positioning and How to Sell that will be available on demand starting tomorrow, February 26th, at the IBM Oracle Virtual University 2013.
It's one of 65 new sessions that will help IBM to surround Oracle applications with IBM infrastructure, services and industry solutions. Oracle software, after all, runs best on IBM hardware. Other highlights of Oracle Virtual University include a live executive State of the Alliance session with Q&A, Oracle keynote, updates by Oracle product managers, sessions on PureSystems, Selling IBM into an Oracle environment, Cloud, and much more.
Visit the [Orace Virtual University 2013 Registration page] to register.
(Update: For employees of IBM, Oracle and their respective business partners, the replays for this event is available until Feb 26, 2014. Visit the [Orace Virtual University 2013 Replay page])
There will be live technical teams on hand throughout launch day to answer your questions in real time, so I hope you can carve out 30 minutes or more on February 26th to take advantage of these available resources.
After helping launch the first Pulse back in 2008, I have sadly not been back since. Last year, I was invited to attend as a last-minute replacement for another speaker, but I was busy [having emergency surgery].
This year's [Pulse 2013] conference looks amazing. It will be held in Las Vegas, Nevada. Guest Speaker Payton Manning, NFL 4-time MVP football player, and Carrie Underwood, 6-time Grammy award winner, join IBM's Software Group executives and experts on how IBM Tivoli can help optimize your IT infrastructure.
Sadly, once again, I will not be there at Pulse. This time, I will be on the East Coast visiting clients instead, but my on-premise correspondent, Tom Rauchut, has informed me that he will be there. Hopefully, he will provide me something to write about.
Later in March, I will be in Brussels, Belgium for the Storage Expo. This is held March 20-21, at the Brussels-Expo venue. I will be presenting several topics each day, as well as visit clients in the area. This event comes on behalf of IBM Belgium in association with IBM Business Partner IRIS-ICT.
If you plan to participate in any of these events, let me know!

The expo opened last night. There are so many fantastic demos and product experts. Las Vegas has a Tivoli buzz on right now.
I'm working in the Hands On Labs room. Pulse labs kicked off Sunday. The hot topics included Cloud, Storage, Automation, Asset Management, and BigFix (a company IBM [acquired and products will now be called Tivoli Endpoint Manager])
I'll try to get you a few updates along the way.

I gotten several emails expressing worry that I have fallen off the face of th earth. The last two weeks have been educational and eye-opening for me. I can't provide details in my blog, so I will just say that it involved government agencies that IBM refers to as "dark accounts", and that I am now back safely in the USA. Between adjusting to time zone differences, ridiculously long hours, and restricted access to the internet, I was unable to blog lately.
Instead, I will resume my coverage of the [IBM System Storage Technical University 2011]. The "Solutions Expo" runs Monday evening through Wednesday lunch. This is a chance for people to explore all the solutions that are part of IBM's large "eco-system" for IBM System storage and System x products. There were several sponsors for this event.
As is often the case at these conferences, the various booths hand out fun items. The hot items this year were tie-dyed tee-shirts from Qlogic, and propeller beanies from the IBM rack and power systems team. Here is Amanda, one of the bartenders showing off the latter.
After the expo on Tuesday night, my friends at [Texas Memory Systems] held an after-party. Unlike the pens, tee-shirts and keychains at the Expo, these guys had a raffle for real storage products. Here is Erik Eyberg handing out a RamSan PCIe card, valued at $14,000 or so. IBM recently certified the TMS RamSan as External SSD storage for the IBM SAN Volume Controller (SVC). The SVC can optimize performance using this for automated sub-LUN tiering with the IBM System Storage Easy Tier feature.

Well, I'm back safely from my tour of Asia. I am glad to report that Tokyo, Beijing and Kuala Lumpur are pretty much how I remember them from the last time I was there in each city. I have since been fighting jet lag by watching the last thirteen episodes of LOST season 6 and the series finale.
Recently, I have started seeing a lot of buzz on the term "Storage Federation". The concept is not new, but rather based on the work in database federation, first introduced in 1985 by [A federated architecture for information management] by Heimbigner and McLeod. For those not familiar with database federation, you can take several independent autonomous databases, and treat them as one big federated system. For example, this would allow you to issue a single query and get results across all the databases in the federated system. The advantage is that it is often easier to federate several disparate heterogeneous databases than to merge them into a single database. [IBM Infosphere Federation Server] is a market leader in this space, with the capability to federate DB2, Oracle and SQL Server databases.
Fellow blogger and BFF, Marc Farley (3PAR) has an excellent post [Zeroing in on a definition for federated storage]. Here's an excerpt:
To some extent, IBM SAN Volume Controller (SVC), XIV, Scale-Out NAS (SONAS), and Information Archive (IA) offer most, if not all, of these capabilities. EMC claims its VPLEX will be able to offer storage federation, but only with other VPLEX clusters, which brings up a good question. What about heterogenous storage federation? Before anyone accuses me of throwing stones at glass houses, let's take a look at each IBM solution:
Even in an ant colony, there are only a few types of ants, with typically one queen, several males, and lots of workers. But all the ants are red. You don't see colonies that mix between different species of ants. For databases, federation was a way to avoid the much harder task of merging databases from different platforms. For storage, I am surprised people have latched on to the term "federation", given our mixed results in the other "federations" we have formed, which I have conveniently (IMHO) ranked from least effective to most effective:
Given the mixed results with "federation", I think I will avoid using the term for storage, and stick to the original term "scale-out architecture".
Well, it's Tuesday again, and you know what that means? IBM Announcements!
Today I want to write about a very recent enhancement for IBM storage clients. This announcement was specific to all IBM Storage clients using IBM Spectrum Control.
IBM recently announced a new solution for existing Spectrum Control clients to obtain a cloud based version and get even more value from their Spectrum Control investment. Whether you have Spectrum Control Standard, Advanced, Select or Virtual Storage Center all versions are covered under this new solution.
In this new solution for existing clients of Spectrum Control, they are entitled to this new solution using existing Spectrum Control licensed capacity. This new solution which is a cloud based Software as a Service (SaaS) offering is titled Storage Insights for Spectrum Control. For current Spectrum Control clients this new solution is provided with no additional costs.
Since the release of Storage Insights & Storage Insights Pro existing clients with Spectrum Control have asked for a similar cloud based option. Today we have that option.
Full details on what is provided In the IBM Storage Insights for Spectrum Control solution can be obtained at [ Storage Insights for Spectrum Control Knowledge Center]
I have provided in the following table a review by version of the features available with this new announcement to the Spectrum Control family of solutions.
If your existing Spectrum Control instance is providing your requirements then consider Storage Insights for Spectrum Control for the added value of enhance IBM Storage Support, and constantly getting access to the latest features of Storage Insights for Spectrum Control without any of the maintenance or upgrade activities.
Whatever reason you may need to reach out to IBM Storage Support, with IBM Support having immediate access to your storage configuration details will reduce the time and your teams effort to get a resolution or recommendation from IBM on how to proceed.
Wrapping up my coverage of the 2013 IT Security and Storage Expo in Belgium, I noticed some interesting things in the other booths.
The EMC booth had a whiteboard so that clients could do some one-on-one collaboration. All of their cocktail waitresses were wearing sharp pin-stripe coats with matching mini-skirts.
Another booth had a "virtual graffiti wall". Using a "digital spraycan", you could write on the wall. I am not sure what connection this had with anything the company had to offer, but perhaps they also wanted to collaborate with attendees on solutions. In either case, it was very cool, and brought a lot of traffic.
(FTC Disclosure: I work for IBM. I was not paid to mention any of the other companies, their products or people on this blog post. Mentioning other companies is not to be considered an endorsement of any kind.)
There were some interesting costumes. Leila from [Aerohive] wearing a "bee costume" complete with black wings. Hans from STS in a bright orange business suit. (Orange is the national color of Belgium). Sophie from Fortinet handed out champagne. The plastic glassware were cones that snapped onto her tray, but they had no flat bottom to rest your glass down, so you had to hold it the entire time until you finished drinking it. The Homer Simpson sticker eating the Apple logo shows the Belgians have a sense of humor!
The NetApp booth had a huge banner claiming that "Data OnTap" was the #1 storage OS. Obviously Windows, AIX, Solaris and Linux aren't consider "storage Operating Systems" per se. Is NetApp claiming they outsell FreeNAS, the only other storage OS that I can think of?
While IBM and I.R.I.S-ICT easily won the "Best Looking Big Booth" award, I have to give the "Best Looking Small Booth" award to my friends at Hitachi Data Systems. Like EMC, the Hitachi team did not have any equipment on the floor, but they made use of their tiny space by having a Japanese theme, with cocktail waitresses in kimonos.
Continuing my coverage of the IT Security and Storage Expo in Brussels, Belgium, we had a nice reception Wednesday evening.
Clara handed out Ceasar Chicken salads. Joelle handed out small rolled up pieces of duck.
Ilsa is an IBM expert in System x, VMware and the PureSystems family on hand to help with the demos and any client questions. I.R.I.S.-ICT employee Ans is only in her 20's, but is recognized as one of Belgium's leading experts in System z mainframe. I used to be the lead architect for DFSMS on z/OS, so we had plenty to talk about.
Of course, the best time for the press to ask for interviews is during the reception, where everyone is relaxed and ready to speak. I am "media-trained" which allows me to speak to the press about IBM matters. I do a lot of these interviews either over the phone, or on camera.
I took a picture to capture the typical setup. Mandy on the left is asking me questions, while camera operator Lisa focuses on my body language. The trick is to spend 80 percent of the time focused on your interviewer, and then 20 percent looking into the camera for strategic pauses. If Mandy decides to use any of the footage, she will be sending me the YouTube video link!
(If you are interested in Media Training, I recommend fellow blogger Brad Phillips' post [21 Most Essential Media Training Links])
Hans and Sophie from Veeam stopped by the IBM booth to say hello. (See 2010 Aug 27 blog post comparing Veeam to Tivoli Storage Manager). These two DJ's kept the IBM and I.R.I.S-ICT booth hopping.
Belgium is a small country, and many of the IT storage people know each other. This made for quite the party! Our group closed up the booth around 8:30pm and we went over to join their friends at Arrow and Huawei. Here is Maiva from Huawei.
The Belgium IT Security and Storage Expo was a great success!
(I am back to the USA in Portland, Oregon this week, so these posts relate to last week.)
However, that wasn't to say I didn't encounter a few challenges during my week in Belgium. The first was getting to the venue. The Belgium Expo is a large complex of buildings to the north of the city. The local IBM team suggested I go to the facility a day in advance so that I would be able to see where it was and how to get there.
I was staying in the center of town, in Place Rogier section. I had many transportation options:
Upon arrival to the building complex, I was unsure of which building I needed to be in. Standing in front of the beautiful Building 5, I found this legend that provided the answer: Building 8. In front of Building 12 was a map that showed where Building 8 was located on the campus.
For this event, IBM joined forces with IBM Business Partner I.R.I.S-ICT to have a fabulous booth, with plenty of experts and equipment demos. As is often the case, the team had to work late into the night to get all the equipment set up, all the podiums and counters constructed, and the demos fully operational.
Apparently, I was not the only one to have troubles finding the place, so I did not feel alone. Some with cars drove around the complex several times before figuring out which parking lot to park in. Others parked at the first spot they found, and still ended up walking as much as I did.
For future reference, If you plan to attend any event at the Belgium Expo, either (a) ask for more explicit directions, and (b) plan to do lots of walking!
Wrapping up this week's theme on the future, fellow blogger David Spark has a great post on his SparkMinute blog titled [20 Brilliant Minds on the future of Hyperconnectivity].
(What does this have to do with Storage? When IBM got back into networking in a big way, they had to decide whether to combine it with one of the existing groups, or form its own group. IBM decided to merge networking with storage, which makes sense since the primary purpose of most networks is to access or transmit information stored somewhere else.)
Last April, the Wharton School and the Institute for the Future convened a one-day [After Broadband] workshop in San Francisco, California, that brought together a group of leading technologists, entrepreneurs, academics and policymakers to explore the future of broadband over the next decade.
At the event, David interviewed 20 people for 10 minutes, and the videos are now available online. Here is one I particularly liked, [David interviewing Bran Ferren of Applied Minds] on Vimeo.
A lot was announced yesterday, so I decided to break it up into several separate posts. This is part 2 in my 3-part series, focusing on: Storwize V7000 Unified, LTO-6 tape, and the SmartCloud Virtual Storage Center.
(to read the rest of the series, see [Part 1-Enterprise Systems: DS8000, TS7700 and XIV])
To learn more about all of the announcements today, see the [Storage Landing Page].

Many thanks to the 186 people who registered for yesterday's webcast "Solving the Storage Capacity Crisis -- Tools and Practices for Effective Management!" We had some excellent questions posed during the live Q&A:
The webcast was recorded, so in case you missed it, or just want to hear it again, the recording is now available in the [On24 archives].
Sorry folks. Due to scheduling conflict, today's Webcast "Solving the Storage Capacity Crisis -- Tools and Practices for Effective Management" has been postponed to September.
The new date is set for September 25. Here is the new [Registration Page]. Even if you were registered for the original one, you will need to register for this one.
Well, it's Tuesday again, and today I am announcing that we have a new IBM Storage blogger joining the Blogosphere: Raj Sharma!
Raj hails from Toronto, Canada and will be able to provide the Canadian perspective on all things Storage. I had the pleasure to meet Raj in person here in Tucson when him and dozens of his cohorts came down for a multi-customer briefing at the [IBM Executive Briefing Center] where I work.
This week, I am in Melbourne, Australia for the [IBM System x and System Storage Technical Symposium]. Here is a recap of Day 1:
technorati tags: IBM, Storage, Symposium, Melbourne, Australia, TPC, Storage Hypervisor, Storwize V7000, SVC, VAAI, vMotion, DWDM, TS1140, 3592-E07, TS3500, LTFS, Emmy, 3592-C07, FICON, The Presidents Cup, Royal Melbourne Golf Club, Tiger Woods, Michael Jordan
Continuing my coverage of the [IBM System x and System Storage Technical Symposium]. Here is a recap of Day 2:
Of course the big news is that U.S. President Barack Obama is here in Australia, with a stop in Canberra (not far from Melbourne), followed by a stop in Darwin on the north side of this country. This is his first official visit to Australia as president.

The Metro Atlanta Chamber (MAC) is focused on bringing businesses and jobs into the Metro Atalanta area, and to help its members connect with other companies that can help them thrive. The MAC cover the Metropolitan region of Atlanta (5.8 million people) and 28 counties in Georgia.
The event was called "Technology Thursday", where the MAC holds a meeting on the third Thursday of every month, to discuss technology issues. The audience was a mix of business owners, sales executives, and managers. The event allowed for people to network with each other, as well as learn something new from a subject matter expert. This was the last one for 2011, to avoid conflicts with upcoming holidays in November and December.
I spoke for an hour, then we raffled off two copies of my latest book, ["Inside System Storage: Volume II"].
Special thanks to Catherine Pearson, Nancy Whatley, and Jim Beach from the MAC, and Karen Harrison from IBM for their support of this event!
IBM had over a dozen storage-related announcements this week. This is my third and final part in my series to provide a quick overview of the announcements.
Whew! I have already heard from some of my readers to slow down, that this is too much information to deal with all at once. IBM has tried everything from having just a few announcements nearly every Tuesday, to having huge launches every two to three years, and settled in the middle with announcements about four to five times per year.
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!
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?
