Wrapping up my coverage of the of the [IBM Edge 2013] conference, I have some photos of people I ran into at the Solutions Center.
Leslie Hattig and Lisa Stone, both account managers for [MarkIII Systems], an IBM Business Partner located in Houston, TX. These ladies are inseparable BFFs, I have never seen one without the other! I first met them at the [Storage Symposium in Chicago] back in 2009.
Stacy Tabor was our Community Manager for the [Storage Community]. This community covers IT Storage challenges, hot topics, architecture and solutions. You'll find industry news, videos, blog discussion threads on timely topics, exclusive analyst white papers and experts opinions. I am a frequent contributor, myself, and thank Stacy for her past service. She helped run a "Social Media Hour" at Edge for all the bloggers like me to get to meet each other.
I could not resist getting a picture with this Las Vegas Cirque du Soleil] dancer. This was an invitation-only event, sponsored by IBM Business Partners, that I was invited to during the Social Media Hour. (See, it pays to be social!) I think the visual effects of the flag she was waving turned out really well in the picture! And yes, in case you are wondering, that is my favorite grape-flavored beverage (GFB) in my left hand. Posing for this picture was quite the balancing act, but then I am also a certified yoga instructor, so I was able to manage!
Tanaz Sowdagar is an IBM Storage Rep for our Business Development Team. This includes finding other companies to OEM our technology and re-brand it under their own names. I have worked with Tanaz for many years, helping answer questions that potential OEM parnters have about our products and technologies for this purpose.
This was Michelle, my Conference Room Monitor. Each room had one, scanning the bar-codes on each badge for all the attendees, keeping count of the number of people for each session, supporting anything the speaker needs, like getting the A/V guy to come help set up the laptop projector.
Since this was Friday, last day of the conference. I decide to dress casually, consistent with many company's [Casual Friday] dress code policy. I am wearing the "IBM Edge Rocks" tee-shirt given out at the concert and Solutions center the first few nights.
Getting this shot right took several takes, as the man I handed my camera to had apparently never seen a digital camera before, did not know how to focus, and some
Finally, leaving Las Vegas, I sat next to Mrs. Joey Clark, wife of "Bulldog" Clark of the Utah band [Blammity Blam]. She also sometimes plays violin with the band. She is a newly-wed, and not sure if Joey is her name, or her husband's name. (Joey, if you are out there, and want me to correctly identify you, please write a comment in the section below.)
What I have learned however, is that if a beautiful girl is sitting next to me on the plane, she will either talk to me the entire flight, implying that she is single, or mention within the first 30 seconds of conversation that she is married. Sadly for me, it was the latter.
(We were both flying on to Dallas, TX, whereupon she was going to visit her parents in Florida, and I was on my way to Sao Paulo, Brazil to get stuck there amongst the protesters in what is now called the [V for Vinegar movement], but I will save that for another blog post!)
Well, that wraps up my coverage of Edge 2013. I am sorry it took so many months to cover all the material, but I did not want to have it go uncovered much longer.
Next year's [Edge 2014] is expected to be bigger and better. It will in Las Vegas again, but this time at the Venetian Hotel, May 19-23, 2014. I plan to be there!

Monday marked the first official day of [IBM Edge 2013] conference. This is actually three conferences in one: Executive Edge for the high-level executives, Winning Edge for the Business Partners, and Technical Edge for storage administrators and IT manager/directors. I attended the latter.
The General Session was kicked off by an awesome drumbeat-heavy song performed by a band from North Carolina called [Delta Rae]. Their use of drums reminded me of Adam Ant.
Deon Newman, IBM VP of Marketing, Systems and Technology Group, North America, served as today's master of ceremonies. He was pleased to announce there were more then 4,700 attendees at this event -- representing more than 60 countries -- a huge increase over the attendance we had last year. Here are my notes of the opening General Session:
Stephen Leonard, IBM General Manager, Sales, Systems & Technology Group
Consumers expect an always-on technology experience. We, as consumers, are leaving a trail of data that is getting wider and wider every day. Data is the new "natural resource", but plentiful and never ending.
In 1996, about 29 percent of IT spend was for adminstration and management, today it has grown to 68 percent. Some 34 percent of IT projects deploy late.
Stephen emphasized the themes of Smarter Computing: (a) systems that are designed for the data, (b) software-defined environments, that are (c) open and collaborative.
Stephen cited a customer example from [Jaguar Land Rover], a manufacturer of sporty automobiles and rugged 4x4 vehicles. IBM developed a ["Virtual Dealership"] for them. Rather that trying to maintain additional physical bricks-and-mortar facilities, which can be expensive to staff and fill with vehicles across their wide portfolio, the virtual dealership allows prospective customers to try out vehicles through simulation. This virtual dealership could be taken to where prospective clients are, such as a sporting event or shopping mall.
Ed Walsh, IBM VP of Marketing, System Storage and Networking
Ed presented the "data economics" of all-Flash arrays. IBM recently acquired Texas Memory Systems, and renamed the RamSan products to IBM FlashSystem, and committed to invest an additional $1 Billion US dollars in flash technologies.
On a $-per-IOPS basis, IBM FlashSystems can be 30 percent lower total-cost-of-ownership TCO than disk-based alternatives. The cost of Flash is offset by 17 percent fewer servers from having higher CPU utilization rates, resuling in 38 percent lower software license fees. Flash is also more efficient, with 74 percent lower in environmental costs, and 35 percent lower operational support costs. For many situations, Flash is the solution for poorly written software applications.
Ed also mentioned IBM's strong support for open source and open standards. Over the past 15 years, IBM as been a major contributor for open source efforts like Linux, Eclipse and Apache. IBM continues that tradition, with contributions to OpenStack and Hadoop.
Without going into any details, Ed also hinted that IBM announced 65 new or refreshed products in Storage, Networking and PureSystems. The details of each announcement would be explained during the break-out sessions during the week.
Charles Long, Founder and CEO of Centerline Digital
[Centerline Digital] does computer-generated animations in support of corporate marketing efforts.
(FTC disclosure: I work for IBM, and have worked closely with Centerline Digital marketing agency when I was the chief marketing strategist for System Storage back in 2006-2007. I was not paid or provided any products or services to mention any of the clients mentioned in this post.)
Charles indicates that internet technologies have converted "Analog dollars to digital pennies". Using IBM PureFlex with Storwize V7000 storage, real-time compression, and Tivoli Endpoint Manager, Centerline was able to drastically improve their business. He feels the old joke of "Better, Faster, Cheaper - Choose Any Two!" no longer applies with IBM solutions!
Ambuj Goyal, IBM General Manager, System Storage and Networking
Formerly my fifth-line manager in charge of Software and Systems, Ambuj switched to be the General Manager of System Storage and Networking group earlier this year.
In his former roles, Ambuj managed software and hardware product lines, but he feels storage is a completely different animal. In the past, clients focused on choosing the best servers, then chose their storage as an afterthought. Today, Ambuj feels that processors are now a commodity, and that storage is becoming the forethought.
Ambuj also highlighted the evolution of IBM's Software-Defined Environment:
In 2003, IBM introduced its the SAN Volume Controller, a storage hypervisor. Now, over 10,000 clients enjoy the benefits of a Software-Defined Environment using SAN Volume Controller.
In the last few years, industry-led innovations that complement SAN Volume Controller were made available, such as [BridgeWorks' SANslide] and [Actifio's Copy Data Storage system].
SmartCloud Virtual Storage Center represents the "third generation" for policy-driven management, combining SAN Volume Controller, Tivoli Storage Productivity Center, FlashCopy Manager and the Storage Analytics Engine.
IBM is trying to help people keep their business critical apps running securely, to be able to start quickly, add value and functions at scale, and to leverage all of this data-intensive solutions to help drive new business and gain customer insight.
Joseph Balsamo, VP of Platform Engineering at Prudential Insurance
While the IT department of [Prudential Insurance] is focused on the three V's -- Volume, Velocity and Variety -- Joe is more focused on solutions, status and cost. His mission was to strengthen the role of IT as a partner through business aligned services. Prudential has deployed XIV, N series, SAN Volume Controller (SVC) and Storwize V7000 disk systems, with the following results:
Reduced their $-per-IOPS by 75 percent
No additional storage administrators
85 percent utilization through thick-to-thin migrations
Reduced their $-per-MB by 50 percent
Reduced their 72-hour RPO to 15 seconds
These benefits were achieved over the past 24 months of deployment.
Paulo Carvao, IBM Vice President, North America Systems & Technology Group
Paulo is Deon Newman's boss. He presented BlueInsight, IBM's internal "Business Analytics" cloud accessible by over 200,000 users, with over 1 PB of content.
Inside IBM, the deployment of a Smarter Infrastructure has allowed for 25 percent capacity growth at flat IT budget, with 30,000 fewer Megawatts and 103,000 square feet.
Bernie Meyerson, IBM Fellow and VP of Innovation
Fellow filmmaker Bernie Meyerson presented the video ["A Boy and his Atom"], which was made by moving individual atoms around with a electronic tunneling microscope. It has been verified by Guinness World Records™ as [The World's Smallest Stop-Motion Film].
Why is this significant? Today's disk writes each bit of information across 1200 atoms, and the smallest number of atoms that can retain information is 12 bits, so sometime in the next 7 to 10 years, the improvements in magnetic bit density for disk will stop.
For silicon chips, the smallest practical feature is 7 nanometers, about 35 atoms wide. We are quickly approaching that limit also.

Happy New Year, everyone!
Continuing this week's theme about the future, fellow blogger, published author, and futurist David Houle is coming out with a new book this month titled [Entering the Shift Age]. This is a follow-on to his book, [The Shift Age].
Since this book cites IBM studies explicitly, his PR department asked me to review it. If you are an aspiring author that has a book you want me review, and it relates to the topics my blog covers like Cloud, Big Data, storage, and the explosion of information, feel free to send me a copy!
(FTC Disclosure: I work for IBM. I was not paid by anyone to mention this book on my blog. I was provided an "Uncorrected Advanced Copy" of this book at no cost to me for this review. I do not know David Houle personally, have not read any of his prior works, nor have I ever seen him speak at public events. This post is neither a paid nor celebrity endorsement of this author, his book, nor any other books by this author.)
First, let's get a few details out of the way:
Title: Entering the Shift Age, 284 pages
Author: David Houle, futurist
Genre: Non-fiction, trends and predictions
Publisher: Sourcebooks, Inc.
Publish date: January 2013
As I mentioned in my post [Historians vs. Futurists], there is only one past, but there are many potential futures. There seems to be as many futurists out there as there are potential futures. I suspect not everyone will agree with all that David has written. However, this reminds me of one of my favorite quotes:
"When two futurists always agree, one is no longer necessary." -- old Italian adage
In his book, David asks a series of thought-provoking questions, then answers them with his views and opinions on how the future will roll out:
- Is humanity now entering a new age that is different than the Information age?
- If so, what should we call it?
- Which forces are driving this new age?
- How will this impact various aspects and institutions of society?
David feels humanity is indeed entering a new age, which he calls the Shift Age. This is driven by three forces: the shift to globalization of culture and politics, the flow of power and influence to individuals, and the acceleration of electronic connectedness.
In a sense, David is like a hunter-gatherer from the Stone age, hunting down trends and gathering ideas from others. In much the same way my compost brings renewed purpose to the rinds and pits of my fruits and vegetables, David's book does a good job paraphrasing the works of many of today's leading futurists.
David predicts the decade we are now in, the 2010's, will mark the end of the Information age, a transition period to this new era, that will lead to transformations in government, education, health, technology, and energy.
Over the past two weeks, I had time to enjoy a variety of movies. I had seen several whose stories wrapped around key moments of transition.
- "Gone with the Wind", as well as the new offering "Lincoln" from Steven Spielberg. Both are set in the 1860's, the time of the [American Civil War], pitting the Industrial-age forces of the North, against the Agricultural-age economy of the South. This time saw the transition from slavery to freedom.
- "Doctor Zhivago", set in the time of World War I, on the German-Russian front, as well as the Russian Revolution of 1917, and the resulting Civil War between the Red Guard and the White Army. This saw the transition from a Russian government ruled by Czars, to one ruled by the people through Communism.
- "Lawrence of Arabia", also set in the time of World War I, but south in Arabia. T. E. Lawrence was able to bring several warring Arab tribes together to defeat the Turks, and was a key figure in the transition to an Arab National Council.
Some might call these completely unexpected [Black Swan] events, while others might feel they are merely fortunate (or misfortunate) sequences of events that led to inevitable social change. Has something happened, or will something happen later this decade, that will drive us to leave the Information Age?
David's previous book, The Shift Age, was published back in 2007, and a lot has happened in the past six years: a global financial melt-down recession; the Arab Spring uprisings in the Middle East; Barack Obama was elected and re-elected; man-made climate change in the form of hurricanes, tsunamis and superstorms hit various parts of the world; brush fires lit up Australia, and BP's Deepwater Horizon oil rig exploded off the Gulf coast, just to name a few.
David's new book reflects the impact of these recent events, from discussions on his [Evolutionshift] blog, to Q&A sessions he has after his public speaking presentations. For those who are not interested in the wide array of topics he covers in this one book, David also offers [a dozen different mini-eBooks] that cover specific topics like [Technology, Energy and Health].
My Rating: Moist and Flaky
Who should read this book: If you are a time-traveler from 1975 that came to this decade to learn all about what your future has in store, but can only select one book to read before you zoom back to your own time period, this would be the book I recommend.
I do not want to imply this is a quick read, or one that you can't put down once you start reading it. Just like you should not gulp down a full bottle of cheap Vodka in one sitting, this book should be read over a series of days, as I did, so that you can mull over in your mind the different points and thoughts he is trying to convey.

If you store your VMware bits on external SAN or NAS-based disk storage systems, this post is for you. The subject of the post, VM Volumes, is a potential storage management game changer!
Fellow blogger Stephen Foskett mentioned VM Volumes in his [Introducing VMware vSphere Storage Features] presentation at IBM Edge 2012 conference. His session on VMware's storage features included VMware APIs for Array Integration (VAAI), VMware Array Storage Awareness (VASA), vCenter plug-ins, and a new concept he called "vVol", now more formally known as VM Volumes. This post provides a follow-up to this, describing the VM Volumes concepts, architecture, and value proposition.
"VM Volumes" is a future architecture that VMware is developing in collaboration with IBM and other major storage system vendors. So far, very little information about VM Volumes has been released. At VMworld 2012 Barcelona, VMware highlights VM Volumes for the first time and IBM demonstrates VM Volumes with the IBM XIV Storage System (more about this demo below). VM Volumes is worth your attention -- when it becomes generally available, everyone using storage arrays will have to reconsider their storage management practices in a VMware environment -- no exaggeration!
But enough drama. What is this all about?
(Note: for the sake of clarity, this post refers to block storage only. However, the VM Volumes feature applies to NAS systems as well. Special thanks to Yossi Siles and the XIV development team for their help on this post!)
The VM Volumes concept is simple: VM disks are mapped directly to special volumes on a storage array system, as opposed to storing VMDK files on a vSphere datastore.
The following images illustrate the differences between the two storage management paradigms.
You may still be asking yourself: bottom line, how will I benefit from VM Volumes?
Well, take a VM snapshot for example. With VM Volumes
, vSphere can simply offload the operation by invoking a hardware snapshot of the hardware volume. This has significant implications:
- VM-Granularity: Only the right VMs are copied (with datastores, backing up or cloning individual-VM portions of hardware snapshot of a datastore would require more complex configuration, tools and work)
- Hardware Offload: No ESXi server resources are consumed
- XIV advantage: With XIV, snapshots consume no space upfront and are completed instantly.
Here's the first takeaway: With VM Volumes, advanced storage services (which cost a lot when you buy a storage array), will become available at an individual VM level. In a cloud world, this means that applications can be provisioned easily with advanced storage services, such as snapshots and mirroring.
Now, let's take a closer look at another relevant scenario where VM Volumes will make a lot of difference - provisioning an application with special mirroring requirements:
- VM Volumes case: The application is ordered via the private cloud portal. The requestor checks a box requesting an asynchronous mirror. He changes the default RPO for his needs. When the request is submitted, the process wraps up automatically: Volumes are created on one of the storage arrays, configured with a mirror and RPO exactly as specified. A few minutes later, the requestor receives an automatic mail pointing to the application virtual machine.
- Datastores case #1: As may be expected, a datastore that is mirrored with the special RPO does not exist. As a result, the automated workflow sets a pending status on the request, creates an urgent ticket to a VMware administrator and aborts. When the VMware admin handles that ticket, she re-assigns the ticket to the storage administrator, asking for a new volume which is mirrored with the special RPO, and mapped to the right ESXi cluster. The next day, the volume is created; the ticket is re-assigned to the storage admin, with the new LUN being pointed to. The VMware administrator follows and creates the datastore on top of it. Since the automated workflow was aborted, the admin re-assigns the ticket to the cloud administrator, who sometime later completes the application provisioning manually.
- Datastores case #2: Luckily for the requestor, a datastore that is mirrored with the special RPO does exist. However, that particular datastore is consuming space from a high performance XIV Gen3 system with SSD caching, while the application does not require that level of performance, so the workflow requires a storage administrator approval. The approval is given to save time, but the storage administrator opens a ticket for himself to create a new volume on another array, as well as a follow-up ticket for the VMware admin to create a new datastore using the new volume and migrate the application to the other datastore. In this case, provisioning was relatively rapid, but required manual follow up, involving the two administrators.
Here's the second takeaway: With VM Volumes, management is simplified, and end-to-end automation is much more applicable. The reason is that there are no datastores. Datastores physically group VMs that may otherwise be totally unrelated, and require close coordination between storage and VMware administrators.
Now, the above mainly focuses on the VMware or cloud administrator perspective. How does VM Volumes impact storage management?
VM's are the new hosts: Today, storage administrators have visibility of physical hosts in their management environment. In a non-virtualized environment, this visibility is very helpful. The storage administrator knows exactly which applications in a data center are storage-provisioned or affected by storage management operations because the applications are running on well-known hosts. However, in virtualized environments the association of an application to a physical host is temporary. To keep at least the same level of visibility as in physical environments, VMs should become part of the storage management environment, like hosts. Hosts are still interesting, for example to manage physical storage mapping, but without VM visibility, storage administrators will know less about their operation than they are used to, or need to. VM Volumes enables such visibility, because volumes are provided to individual VMs. The XIV VM Volumes demonstration at VMworld Barcelona, although experimental, shows a view of VM volumes, in XIV's management GUI.
Here's a screenshot:
That's not all!
Storage Profiles and Storage Containers: A Storage Profile is a vSphere specification of a set of storage services. A storage profile can include properties like thin or thick provisioning, mirroring definition, snapshot policy, minimum IOPS, etc.
- Storage administrators define a portfolio of supported storage services, maintained as a set of storage profiles, and published (via VASA integration) to vSphere.
- VMware or cloud administrators define the required storage profiles for specific applications
VMware and storage administrators need to coordinate the typical storage requirements and the automatically-available storage services. When a request to provision an application is made, the associated storage profiles are matched against the published set of available storage profiles. The matching published profiles will be used to create volumes, which will be bound to the application VMs. All that will happen automatically.
Note that when a VM is created today, a datastore must be specified. With VM Volumes, a new management entity called Storage Container (also known as Capacity Pool) replaces the use of datastore as a management object. Each Storage Container exposes a subset of the available storage profiles, as appropriate. The storage container also has a capacity quota.
Here are some more takeaways
- New way to interface vSphere and storage management: Storage administrators structure and publish storage services to vSphere via storage profiles and storage containers.
- Automated provisioning, out of the box: The provisioning process automatically matches application-required storage profiles against storage profiles available from the specified storage containers. There is no need to build custom scripts and custom processes to automate storage provisioning to applications
- The XIV advantage:
- XIV services are very simple to define and publish. The typical number of available storage profiles would be low. It would also be easy to define application storage profiles.
- XIV provides consistent high performance, up to very high capacity utilization levels, without any maintenance. As a result, automated provisioning (which inherently implies less human attention) will not create an elevated risk of reduced performance.
Note: A storage vendor VASA provider is required to support VM Volumes, storage profiles, storage containers and automated provisioning. The IBM Storage VASA provider runs as a standalone service that needs to be deployed on a server.
To summarize the VM Volumes value proposition:
- Streamline cloud operation by providing storage services at VM and application level, enabling end-to-end provisioning automation, and unifying VMware and storage administration around volumes and VMs.
- Increase storage array ROI, improve vSphere scalability and response time, and reduce cloud provisioning lag, by offloading VM-level provisioning, failover, backup, storage migration, storage space recycling, monitoring, and more, to the storage array, using advanced storage operations such as mirroring and snapshots.
- Simplify the adoption of VM Volumes using XIV, with smaller and simpler sets of storage profiles. Apply XIV's supreme fast cloning to individual VMs, and keep automation risks at bay with XIV's consistent high performance.
For additional information about VM Volumes, check out [VMware Storage APIs for VM and Application Granular Data Management] blog post by Duncan Epping, a Principal Architect in the Technical Marketing group at VMware!
Until you can get your hands on a VM Volumes-capable environment, the VMware and IBM developer groups will be collaborating and working hard to realize this game-changing feature. The above information is definitely expected to trigger your questions or comments, and our development teams are eager to learn from them and respond. Enter your comments below, and I will try to answer them, and help shape the next post on this subject. There's much more to be told.

Well, it's Tuesday again, and you know what that means... IBM Announcements!
This month, I am celebrating my six-year "blogoversary". I started blogging September 1, 2006 to celebrate [the 50th anniversary of disk system innovations].
This month, I am pleased to announce the new [IBM STG Executive Briefing Center] website, representing a huge improvement over the previous website we had been using over the past two years. STG refers to IBM's Systems and Technology Group, the division that focuses on servers, storage, switches and the system software that makes them run. This new website is for the dozen STG EBCs that span the globe. The new website reminds me of this famous quote:
"Perfection is achieved, not when there is nothing left to add, but when there is nothing left to take away"
-- Antoine de Saint-Exupery
Let's take a quick look at what makes it so much better.
- Self-service Portal
The previous website required registration. At every briefing, those of us who work in the EBCs had to pass around a sign-up sheet for email addresses from each attendee so that we could send them an invitation to register for the site. We would have a hard time reading people's handwriting, resulting in some emails coming back rejected.
Inspired by self-service gas stations, automated teller machines, and the many self-service portals of Cloud Computing, the new website has everything up-front, without registration. IBM Business Partners and sales representatives can easily request a briefing at any of the dozen briefing centers represented!
- IBM-managed and IBM-hosted
We had a difficult time explaining to our attendees why our previous website was hosted on a lone machine and maintained by a third party. Think about it, IBM manages the data centers of over 400 clients. IBM has provided web hosting to the most mission critical workloads, with high levels of availability and reliability, and is recognized as one of the "Big 5" Cloud companies. I have done web design myself in my career, and we were terribly disappointed with the third party chosen to create and maintain our previous website, constantly having to point out errors in their HTML and CSS.
For the new website, IBM took back control. Staff from each EBC, myself included, came up with a simple page to bring the essence of each location to life. Special thanks to my colleage Hal Jennings, from the Austin EBC, for bringing this altogether!
- Simplified Navigation
Despite two years of manually registering attendees to use the previous website, Google Analytics showed that few people visited, and the few that did spent little time exploring the vast repository of content.
The new website is vastly simpler. The front page points to all twelve EBCs, and a single mouse click gets you to the location you are interested in, with all the details you need to make a decision to book a briefing, and the contact information to make it happen.
- Elimination of Wasted and Duplicate Effort
In the previous website, we spent as much as 15 hours just to create, voice over, edit and produce a single 15-minute recorded presentation. Less than six percent of the previous website visitors watched more than five minutes of these videos, making us feel that most of our effort was wasted.
The EBC staff kept wasting their time, month after month, thanks to all-stick, no-carrot tactics that mandated minimums for contributions for more and more content that nobody was ever looking at. Even more disappointing was that much of our work duplicated the formal responsibilities of our IBM Marketing team. They weren't happy about this either, causing confusion between the roles of our two teams.
Finally, we said enough was enough! The new STG EBC website is a marvel in minimalism. If you want to see presentations, videos, expert profiles, or partake in on-going conversations, I welcome you to visit the [IBM Expert Network], the [IBM Storage YouTube Channel], and the [Storage Community] where they belong.
I invite you all to check out the new [IBM STG Executive Briefing Center] website. Let me know what you think in the comments below!

Can Structured Query Language [SQL] be considered a storage protocol?
Several months ago, I was asked to review a book on SQL, titled appropriately enough "The Complete Idiot's Guide to SQL", by Steven Holzner, Ph.D. As a published author myself, I get a lot of these requests, and I agreed in this case, given that SQL was invented by IBM, and is a good fundamental skill to have for Business Analytics and Database Management.
(FTC Disclosure: I work for IBM but was not part of the SQL development team. I was provided a copy of this book for free to review it. I was not paid to mention this book, nor told what to write. I do not know the author personally nor anyone that works for his publicist. All of my opinions of the book in this blog post are my own.)
Despite an agreed-upon standard for SQL, each relational database management system (RDBMS) has decided to customize it for their own purposes. First, SQL can be quite wordy, so some RDBMS have made certain keywords optional. Second, RDBMS offer extra features by adding keywords or programming language extentions, options or parameters above and beyond what the SQL standard calls for. Third, the SQL standard has changed over the years, and some RDBMS have opted to keep some backward compatibility with their prior releases. Fourth, some RDBMS want to discourage people from easily porting code from one RDBMS to another, known in the industry as vendor lock-in.
Throughout my career, I have managed various databases, including Informix, DB2, MySQL, and Microsoft SQL Server, so I am quite familiar with the differences in SQL and the problems and implications that arise.
Most authors who want to write about SQL typically make a choice between (a) stick to the SQL standard, and expect the reader to customize the examples to their particular DBMS; or (b) stick to a single RDBMS implemenation, and offer examples that may not work on other RDBMS.
I found the book "The Complete Idiot's Guide to SQL" covered the basics quite well, but with an odd twist. The basics include creating databases and tables, defining columns, inserting and deleting rows, updating fields, and performing queries or joins. The odd twist is that Steven does not make the typical choice above, but rather shows how the various DBMS are different than standard SQL syntax, with actual working examples for different RDBMS.
You might be thinking to yourself that only an idiot would work in a place that had to require knowledge of multiple RDBMS. The sad truth is that most of the medium and large companies I speak to have two or more in production. This is either through acquisitions, or in some cases, individual business units or departments implementing their own via the [Shadow IT].
(For those who want to learn SQL and try out the examples in this book, IBM offers a free version of DB2 called [DB2-C Express] that runs on Windows, Linux, Mac OS, and Solaris.)
Last week, while I was in Russia for the [Edge Comes to You] event, I was interviewed by a journalist from [Storage News] on various topics. One question stuck me as strange. He asked why I did not mention IBM's acquisition of Netezza in my keynote session about storage. I had to explain that Netezza was not in the IBM System Storage product line, it is in a different group, under Business Analytics, where it belongs.
While it is true that Netezza can store data, because it has storage components inside, the same could also be said about nearly every other piece of IT equipment, from servers with internal disk, to digital cameras, smart phones and portable music players. They can all be considered storage devices, but doing so would undermine what differentiates them from one another.
Which brings me back to my original question: Should we consider SQL to be a storage protocol? For the longest time, IT folks only considered block-based interfaces as storage protocols, then we added file-based interfaces like CIFS and NFS, and we also have object-based interfaces, such as IBM's Object Access Method (OAM) and the System Storage Archive Manager (SSAM) API. Could SQL interfaces be the next storage protocol?
Let me know what you think on this. Leave a comment below.

This week, I am in beautiful Sao Paulo, Brazil, teaching Top Gun class to IBM Business Partners and sales reps. Traditionally, we have "Tape Thursday" where we focus on our tape systems, from tape drives, to physical and virtual tape libraries. IBM is the number #1 tape vendor, and has been for the past eight years.
(The alliteration doesn't translate well here in Brazil. The Portuguese word for tape is "fita", and Thursday here is "quinta-feira", but "fita-quinta-feira" just doesn't have the same ring to it.)
In the class, we discussed how to handle common misperceptions and myths about tape. Here are a few examples:
- Myth 1: Tape processing is manually intensive
In my July 2007 blog post [Times a Million], I coined the phrase "Laptop Mentality" to describe the problem most people have dealing with data center decisions. Many folks extend linearly their experiences using their PCs, workstations or laptops to apply to the data center, unable to comprehend large numbers or solutions that take advantage of the economies of scale.
For many, the only experience dealing with tape was manual. In the 1980s, we made "mix tapes" on little cassettes, and in the 1990s we recorded our favorite television shows on VHS tapes in the VCR. Today, we have playlists on flash or disk-based music players, and record TV shows on disk-based video recorders like Tivo. The conclusion is that tapes are manual, and disk are not.
Manual processing of tapes ended in 1987, with the introduction of a silo-like tape library from StorageTek. IBM quickly responded with its own IBM 3495 Tape Library Data Server in 1992. Today, clients have many tape automation choices, from the smallest IBM TS2900 Tape Autoloader that has one drive and nine cartridges, all the way to the largest IBM TS3500 multiple-library shuttle complex that can hold exabytes of data. These tape automation systems eliminate most of the manual handling of cartridges in day-to-day operations.
- Myth 2: Tape media is less reliable than disk media
For any storage media to be unreliable is to return the wrong information that is different than what was originally stored. There are only two ways for this to happen: if you write a "zero" but read back a "one", or write a "one" and read a "zero". This is called a bit error. Every storage media has a "bit error rate" that is the average likelihood for some large amount of data written.
According to the latest [LTO Bit Error rates, 2012 March], today's tape expects only 1 bit error per 10E17 bits written (about 100 Petabytes). This is 10 times more reliable than Enterprise SAS disk (1 bit per 10E16), and 100 times more reliable than Enterprise-class SATA disk (1 bit per 10E15).
Tape is the media used in "black boxes" for airplanes. When an airplane crashes, the black box is retrieved and used to investigate the causes of the crash. In 1986, the Space Shuttle Challenger exploded 73 seconds after take-off. The tapes in the black box sat on the ocean floor for six weeks before being recovered. Amazingly, IBM was able to successfully restore [90 percent of the block data, and 100 percent of voice data].
- Myth 3: Most tape restores fail
Why do people still believe that most tape restores fail? Curtis Preston, on his Backup Central blog, has a great post [Gartner Never Said 71 percent of Tape Restores Fail].
Analysts are quite upset when they are quoted out of context, but in this case, Gartner never said anything closely similar to this. Nor did the other analysts that Curtis investigated for similar claims. What Garnter did say was that disk provides an attractive alternative storage media for backup which can increase the performance of the recovery process.
Back in the 1990s, Savur Rao and I developed a patent to help backup DB2 for z/OS by using the FlashCopy feature of IBM's high-end disk system. The software method to coordinate the FlashCopy snapshots with the database application and maintain multiple versions was implemented in the DFSMShsm component of DFSMS. A few years later, this was part of a set of patents IBM cross-licensed to Microsoft for them to implement a similar software for Windows called Data Protection Manager (DPM). IBM has since introduced its own version for distributed systems called IBM Tivoli FlashCopy Manager that runs not just on Windows, but also AIX, Linux, HP-UX and Solaris operating systems.
Curtis suspects the "71 percent" citation may have been propogated by an ambitious product manager of Microsoft's Data Protection Manager, back in 2006, perhaps to help drive up business to their new disk-based backup product. Certainly, Microsoft was not the only vendor to disparage tape in this manner.
A few years ago, an [EMC failure brought down the State of Virginia] due to not just a component failure it its production disk system, but then made it worse by failing to recover from the disk-based remote mirror copy. Fortunately, the data was able to be restored from tape over the next four days. If you wonder why nobody at EMC says "Tape is Dead" anymore, perhaps it is because tape saved their butts that week.
(FTC Disclosure: I work for IBM and this post can be considered a paid, celebrity endorsement for all of the IBM tape and software products mentioned on this post. I own shares of stock in both IBM and Google, and use Google's Gmail for my personal email, as well as many other Google services. While IBM, Google and Microsoft can be considered competitors to each other in some areas, IBM has working relationships with both companies on various projects. References in this post to other companies like EMC are merely to provide illustrative examples only, based on publicly available information. IBM is part of the Linear Tape Open (LTO) consortium.)
Last year, Google lost the email data for half a million Gmail accounts due to a software error. Once again, tape came to the rescue, with [Google restoring lost Gmail data from tape backups].
- Myth 4: Vendors and Manufacturers are no longer investing in tape technology
IBM and others are still investing Research and Development (R&D) dollars to improve tape technology. What people don't realize is that much of the R&D spent on magnetic media can be applied across both disk and tape, such as IBM's development of the Giant Magnetoresistance read/write head, or [GMR] for short.
Most recently, IBM made another major advancement with tape with the introduction of the Linear Tape File Systems (LTFS). This allows greater portability to share data between users, and between companies, but treating tape cartridges much like USB memory sticks or pen drives. You can read more in my post [IBM and Fox win an Emmy for LTFS technology]!
Next month, IBM celebrates the 60th anniversary for tape. It is good to see that tape continues to be a vibrant part of the IT industry, and to IBM's storage business!

Well, it's Tuesday again, and you know what that means!
This Thursday is the Thanksgiving holiday here in the United States, so instead of announcing IBM products, I wanted to announce the general availability of my latest book, [Inside System Storage: Volume III].
This book includes blog posts from May 2008 to March 2009, along with the ever popular behind-the-scenes commentary on what was going on during IBM's launch of the Information Infrastructure initiative.
- Do you know someone who celebrates Chanukah, Christmas, Kwanza, or the Winter Solstice, and have a hard time finding the right gift?
- Do you know a client or IBM Business Partner that would appreciate a nominally-priced gift to thank them for their business?
- Do you know someone newly hired into IBM or another IT company that could benefit from behind-the-scenes insight and commentary?
As with the other two volumes, Inside System Storage: Volume III is available in your choice of paperback, hardcover, and eBook (Adobe PDF) format.
In the spirit of Thanksgiving, I would like to thank my editor, Susan Pollard, who put in the extra effort, working evenings and weekends, to get this book done in time for the upcoming holiday season. For those outside the United States, there is an American tradition to shop in brick-and-mortar stores on Black Friday (the day after Thanksgiving) and to shop on-line for books like mine on Cyber Monday (the Monday after Thanksgiving).
I would also like to thank my publisher, Lulu.com, for upgrading me to "Spotlight" level, so now I have a spotlight page titled [Books Written by Tony Pearson], making it easy for you to order any of my books in various formats.
And last, but not least, I would like to thank all my friends and family that were supportive these past few difficult months while I was putting this book together.
Next month, I will be in Las Vegas, Dec 4-8, speaking at Gartner's [Data Center Conference]. If you order a book today, and bring it with you to the IBM booth at the Solution Expo, I can sign it for you!

This week, IBM made over a dozen announcements related to IBM storage products. Here is part 2 of my overview:
- IBM System Storage® DS8000 series microcode
One of the advantages of acquiring XIV as IBM's other high-end disk system, is that it allows the DS8000 team to focus on the IBM i and z/OS operating systems. As a result, IBM DS8000 has over half the mainframe-attach market share.
For both the DS8700 and DS8800 models, IBM Easy Tier now support sub-LUN automated tiering across three storage tiers: Solid-State Drives, high-performance spinning disk drives (15K and 10K RPM), and high-capacity disk drives (7200 RPM).
For System z customers, the latest DS8000 microcode has synergy with z/OS and GDPS, now supporting 4x larger EAV volumes, faster high-performance FICON (zHPF), and Workload Manager (WLM) integration with the I/O Priority Manager. IBM has a world record SAP performance of 59 million account postings per hour. DB2 v10 for z/OS queries were measured at 11x faster using the new zHPF feature.
- IBM System Storage® DS8800 systems
On the hardware side, the DS8800 now supports a fourth frame to hold a total over 1,500 disk drives. Yes, we have customers that three frames wasn't enough, and they wanted more.
IBM is now also offering new drive options. Small Form Factor (2.5 inch) drives now include 300GB 15K RPM drives, and a 900GB 10K RPM drives. But wait! There's more! The DS8800 is no longer a SFF-only box, it now allows for mixing in Large form factor (3.5 inch) drives, starting with the 3TB NL-SAS 7200 RPM drive.
- IBM XIV® Storage System Gen3
We announced the XIV Gen3 already, but we have two enhancements.
First, we now offer a model based entirely on 3TB NL-SAS drives. If you are thinking, what IBM is going to put 3TB drives into everything? Yup. Once we go through all the pain and suffering of qualifying a drive, we make sure we get our money's worth!
Secondly, we have now an iPad application to manage the XIV. This has nothing to do with Apple CEO Steve Jobs passing away last week, it was merely coincidence.
- IBM Real-time Compression Appliances™ STN6500 and STN6800 V3.8
The latest software for RtCA now supports Microsoft SMB v2, and enhanced reporting so that storage admins know exactly the benefits of the compression ratios of different file extensions.
- IBM System Storage EXP2500 Express®
The EXP2500 is for direct-attach situations, like the IBM BladeCenter. IBM adds LFF 3.5-inch 3TB NL-SAS drives, SFF 2.5-inch 300GB 15K RPM SAS drives, and 900GB 7200 RPM NL-SAS drives.
My colleague Curtis Neal refers to these as "B.F.D" announcements, which of course stands for Bigger, Faster, Denser!

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:
"The idea of shopping from a catalog isn’t new and the cost efficiency it offers to the supplier isn’t new either. Public storage cloud service providers seized on the catalog idea quickly as both a means of providing a clear description of available services to their clients, and of controlling costs. Here’s the idea… I can go to a public cloud storage provider like Amazon S3, Nirvanix, Google Storage for Developers, or any of a host of other providers, give them my credit card, and get some storage capacity. Now, the “kind” of storage capacity I get depends on the service level I choose from their catalog.
Most of today’s private IT environments represent the complete other end of the pendulum swing – total customization. Every application owner, every business unit, every department wants to have complete flexibility to customize their storage services in any way they want. This expectation is one of the reasons so many private IT environments have such a heavy mix of tier-1 storage. Since there is no structure around the kind of requests that are coming in, the only way to be prepared is to have a disk array that could service anything that shows up. Not very efficient… There has to be a middle ground.
Private storage clouds are a little different. Administrators we talk to aren’t generally ready to let all their application owners and departments have the freedom to provision new storage on their own without any control. In most cases, new capacity requests still need to stop off at the IT administration group. But once the request gets there, life for the IT administrator is sweet!
Here comes the request from an application owner for 500GB of new “Database” capacity (one of the options available in the storage service catalog) to be attached to some server. After appropriate approvals, the administrator can simply enter the three important pieces of information (type of storage = “Database”, quantity = 500GB, name of the system authorized to access the storage) and click the “Go” button (in TPC SE it’s actually a “Run now” button) to automatically provision and attach the storage. No more complicated checklists or time consuming manual procedures.
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.
- Want faster time-to-market? A storage hypervisor can help reduce the time it takes to provision storage, from weeks down to minutes. If your business needs to react quickly to changes in the marketplace, you certainly don't want your IT infrastructure to slow you down like a boat anchor.
- Want more time with your friends and family? A storage hypervisor can migrate the data non-disruptively, during the week, during the day, during normal operating hours, instead of scheduling down-time on an evenings and weekends. As companies adopt a 24-by-7 approach to operations, there are fewer and fewer opportunities in the year for scheduled outages. Some companies get stuck paying maintenance after their warranty expires, because they were not able to move the data off in time.
- Want to take advantage of the new Solid-State Drives? Most admins don't have time to figure out what applications, workloads or indexes would best benefit from this new technology? Let your storage hypervisor automated tiering do this for you! In fact, a storage hypervisor can gather enough performance and usage statistics to determine the characteristics of your workload in advance, so that you can predict whether solid-state drives are right for you, and how much benefit you would get from them.
- Want more time spent on strategic projects? A storage hypervisor allows any server to connect to any storage. This eliminates the time wasted to determine when and how, and let's you focus on the what and why of your more strategic transformational projects.
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 [
'Storage Virtualization' or 'Virtualization-Optimized Storage Management'?] Here is an excerpt:
"Server virtualization is a fairly easy concept to understand: Add a layer of software that allows processing capability to work across multiple operating environments. It drives both efficiency and performance because it puts to good use resources that would otherwise sit idle.
Storage virtualization is a different animal. It doesn't free up capacity that you didn't know you had. Rather, it allows existing storage resources to be combined and reconfigured to more closely match shifting data requirements. It's a subtle distinction, but one that makes a lot of difference between what many enterprises expect to gain from the technology and what it actually delivers."
Jon Toigo on his DrunkenData
blog brings back the sanity with his post [Once More Into the Fray
]. Here is an excerpt:
"What enables me to turn off certain value-add functionality is that it is smarter and more efficient to do these functions at a storage hypervisor layer, where services can be deployed and made available to all disk, not to just one stand bearing a vendor’s three letter acronym on its bezel. Doesn’t that make sense?
I think of an abstraction layer. We abstract away software components from commodity hardware components so that we can be more flexible in the delivery of services provided by software rather than isolating their functionality on specific hardware boxes. The latter creates islands of functionality, increasing the number of widgets that must be managed and requiring the constant inflation of the labor force required to manage an ever expanding kit. This is true for servers, for networks and for storage.
Can we please get past the BS discussion of what qualifies as a hypervisor in some guy’s opinion and instead focus on how we are going to deal with the reality of cutting budgets by 20% while increasing service levels by 10%. That, my friends, is the real challenge of our times."
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 blogging-about-blogging posts, then by all means stop reading now!)
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.
-- Arthur Bloch [Yale Book of Quotations]
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].

After the amount of flack Jon Toigo had to endure for not giving advanced notice to his upcoming Webcast, I thought I would better remind people about my own Webinar that is happening next Tuesday, August 23.
Fortunately, they do not overlap. Mine is at 1pm EDT, and Jon's Webcast is Part 4 of his Storage Virtualization series, [The Data Protection Imperative: How to Keep Rockin’ and Not Lose Your Assets] is earlier in the morning.
So here's the scoop, next Tuesday I will be presenting [The Future of Storage], August 23, 1pm to 2pm EDT. You can register to attend at the [Infoboom Registration Page]. Infoboom is a social community for business and IT leaders of small and midsize businesses brought to you by IBM.
But that's not all! After the webinar, I will then travel to various cities for face-to-face lectures. Here are the first two:
- September 7 - Indianapolis
- September 8 - Boston area
If you are near either of these two locations, contact your local IBM storage specialist or IBM business partner to participate.

The IBM Storwize V7000 was introduced last October, and has proven to be wildly successful. I saw two awesome reviews recently of the IBM Storwize V7000 disk system that I thought I would bring to your attention.
The first review is [IBM Storwize V7000] from Roger Howorth of ZDNet UK. Here are some quotes:
- "Under the hood, the Storwize V7000 is built from technologies originally developed for IBM's enterprise-class storage systems, so the V7000 benefits from a comprehensive set of high-end features that have been scaled down for mid-range buyers."
- "Initial configuration couldn't be simpler."
- "We really liked the layout and functionality of the GUI."
The second review is [IBM Storwize V7000 Disk System: Enterprise-class Function in a Midrange Storage Package] from Tony Palmer of Enterprise Strategy Group (ESG). Here are some quotes:
- "Storwize V7000 is virtual storage that offers efficiency and flexibility through built-in SSD optimization and "thin provisioning" technologies while enabling users to virtualize and re-use existing disk systems..."
- "Storwize V7000 advanced functionality also enables non-disruptive migration of data from existing storage, simplifying implementation and minimizing disruption to users."
- "The Storwize V7000 graphical user interface is a browser-based, easy to navigate intuitive GUI."
- "ESG Lab found that getting started with the Storwize V7000 disk system was intuitive and straightforward."
- "Easy Tier increases the efficiency and simplicity of deploying SSD drives."
This is a great review, following the February ESG Report on [IBM Storwize V7000: Real-world Mixed Workload Performance in VMware Environments].
If you are looking for midrange storage with a nice set of enterprise-class features, consider the Storwize V7000!

Well, it's Tuesday again, and you know what that means... IBM Announcements!
IBM thought the week that everyone is watching IBM Watson compete against humans on Jeopardy! would be a good week to launch new storage products.
- IBM XIV Storage System
Ever since my post [Double Drive Failure Debunked: XIV Two Years Later], the XIV storage systems have been flying off the shelves. IBM rolls out the new [XIV 10.2.4 microcode level] with some exciting new software features. Here are the highlights:
Full VMware Vstorage API for Array Integration (VAAI). Back in 2008, VMware announced new vStorage APIs for its vSphere ESX hypervisor: vStorage API for Site Recovery Manager, vStorage API for Data Potection, vStorage API for Multipathing. Last July, VMware added a new API called vStorage API for Array Integration [VAAI] which offers three primitives:
- Hardware-assisted Blocks zeroing. Sometimes referred to as "Write Same", this SCSI command will zero out a large section of blocks, presumably as part of a VMDK file. This can then be used to reclaim space on the XIV on thin-provisioned LUNs.
- Hardware-assisted Copy. Make an XIV snapshot of data without any I/O on the server hardware.
- Hardware-assisted locking. On mainframes, this is call Parallel Access Volumes (PAV). Instead of locking an entire LUN using standard SCSI reserve commands, this primitive allows an ESX host to lock just an individual block so as not to interfere with other hosts accessing other blocks on that same LUN.
Plans for a [fourth primitive called "Thin Provisioning Stun"] were mysteriously dropped. For now, VAAI support refers only to the three primitives above.
(Stephen, if you are reading this, please update your [VAAI in Plain English Support Matrix].)
Quality of Service (QoS) Performance Classes.
When XIV was first released, it treated all hosts and all data the same, even when deployed for a variety of different applications. This worked for some clients, such as [Medicare y Mucho Más]. They migrated their databases, file servers and email system from EMC CLARiiON to an IBM XIV Storage System. In conjunction with VMware, the XIV provides a highly flexible and scalable virtualized architecture, which enhances the company's business agility.
However, other clients were skeptical, and felt they needed additional "nobs" to prioritize different workloads. The new 10.2.4 microcode allows you to define four different "performance classes". This is like the door of a nightclub. All the regular people are waiting in a long line, but when a celebrity in a limo arrives, the bouncer unclips the cord, and lets the celebrity in. For each class, you provide IOPS and/or MB/sec targets, and the XIV manages to those goals. Performance classes are assigned to each host based on their value to the business.
Offline Initialization for Asynchronous Mirror.
Internally, we called this Truck Mode. Normally, when a customer decides to start using Asynchronous Mirror, they already have a lot of data at the primary location, and so there is a lot of data to send over to the new XIV box at the secondary location. This new feature allows the data to be dumped to tape at the primary location. Those tapes are shipped to the secondary location and restored on the empty XIV. The two XIV boxes are then connected for Asynchronous Mirroring, and checksums of each 64KB block are compared to determine what has changed at the primary during this "tape delivery time". This greatly reduces the time it takes for the two boxes to get past the initial synchronization phase.
- IBM Storwize V7000 Rapid Application Storage
Last month, IBM announced the [IBM Storwize V7000 Rapid Application Storage] bundle. There is now a [Business Advantage Calculator] to help cost-justify this bundle.
IP-based Replication. When IBM first launched the Storwize V7000 last October, people commented that the one feature they felt missing was IP-based replication. Sure, we offered FCP-based replication as most other Enterprise-class disk systems offer today, but many midrange systems also offer IP-based repliation to reduce the need for expensive FCIP routers. [IBM Tivoli Storage FastBack for Storwize V7000] provides IP-based replication for Storwize V7000 systems.
- Network Attached Storage
IBM announced two new models of the IBM System Storage N series. The midrange N6240 supports up to 600 drives, replacing the N6040 system. The entry-level N6210 supports up to 240 drives, and replaces the N3600 system. Details for both are available on the latest [data sheet].
IBM Real-Time Compression appliances work with all N series models to provide additional storage efficiency. Last October, I provided the [Product Name Decoder Ring] for the STN6500 and STN6800 models. The STN6500 supports 1 GbE ports, and the STN6800 supports 10GbE ports (or a mix of 10GbE and 1GbE, if you prefer). The IBM versions of these models were announced last December, but some people were on vacation and might have missed it. For more details of this, read the [Resources page], the [landing page], or [watch this video].
- IBM System Storage DS3000 series
IBM System Storage [DS3524 Express DC and EXP3524 Express DC] models are powered with direct current (DC) rather than alternating current (AC). The DS3524 packs dual controllers and two dozen small-form factor (2.5 inch) drives in a compact 2U-high rack-optimized module. The EXP3524 provides addition disk capacity that can be attached to the DS3524 for expansion.
Large data centers, especially those in the Telecommunications Industry, receive AC from their power company, then store it in a large battery called an Uninterruptible Power Supply (UPS). For DC-powered equipment, they can run directly off this battery source, but for AC-powered equipment, the DC has to be converted back to AC, and some energy is lost in the conversion. Thus, having DC-powered equipment is more energy efficient, or "green", for the IT data center.
Whether you get the DC-powered or AC-powered models, both are NEBS-compliant and ETSI-compliant.
- New Tape Drive Options for Autoloaders and Libraries
IBM System Storage [TS2900 Autoloader] is a compact 1U-high tape system that supports one LTO drive and up to 9 tape cartridges. The TS2900 can support either an LTO-3, LTO-4 or LTO-5 half-height drive.
IBM System Storage [TS3100 and TS3200 Tape Libraries] were also enhanced. The TS3100 can accomodate one full-height LTO drive, or two half-height drives, and hold up to 24 cartridges. The TS3200 offers twice as many drives and space for cartridges.
For more on this, see the [1Q2011 Storage Announcements page].

Well, it's Thursday, and today IBM is having a major launch for storage. We have lots of exciting announcements today, so here is the major highlights:
- IBM Storwize V7000 midrange disk system
Fellow blogger Rolf Potts just completed his [No Baggage Challenge], travelling around the world, twelve countries in six weeks with no luggage. I first learned of this trip from fellow published author and blogger Tim Ferriss in his post [How to Travel 12 Countries with No Baggage Whatsoever]. This trip was sponsored by a travel agency [BootsnAll.com] and travel clothing manufacturer [ScotteVest].
From New York, Rolf went to London, Paris, Madrid, Morocco, Cairo, South Africa, Bangkok Thailand, Malaysia, Singapore, New Zealand, Australia, and then back to United States. I was hoping to run into him while I was in Australia and New Zealand last month, but our schedules did not line up.
Travelingwithout baggage is more than just a convenience, it is a metaphor for the philosophy that we should keep only what we need, and leave behind what we don't. This was the approach taken by IBM in the design of the IBM Storwize V7000 midrange disk system.
The IBM Storwize V7000 disk system consists of 2U enclosures. Controller enclosures have dual-controllers and drives. Expansion enclosures have just drives. Enclosures can have either 24 smaller form factor (SFF) 2.5-inch drives, or twelve larger 3.5-inch drives. A controller enclosure can be connected up to nine expansion enclosures.
The drives are all connected via 6 Gbps SAS, and come in a variety of speeds and sizes: 300GB Solid-State Drive (SSD); 300GB/450GB/600GB high-speed 10K RPM; and 2TB low-speed 7200 RPM drives. The 12-bay enclosures can be intermixed with 24-bay enclosures on the same system, and within an enclosure different speeds and sizes can be intermixed. A half-rack system (20U) could hold as much as 480TB of raw disk capacity.
This new system, freshly designed entirely within IBM, competes directly against systems that carry a lot of baggage, including the HDS AMS, HP EVA, an EMC CLARiiON CX4 systems. Instead, we decided to keep the what we wanted from our other successful IBM products.
- Inspired by our successful XIV storage system, IBM has developed a web-based GUI that focuses on ease-of-use. This GUI uses the latest HTML5 and dojo widgets to provide an incredible user experience.
- Borrowed from our IBM DS8000 high-end disk systems, state-of-the-art device adapters provide 6 Gbps SAS connectivity with a variety of RAID levels: 0, 1, 5, 6, and 10.
- From our SAN Volume Controller, the embedded [ SVC 6.1 firmware] provides all of the features and functions normally associated with enterprise-class systems, including Easy Tier sub-LUN automated tiering between Solid-State Drives and Spinning disk, thin provisioning, external disk virtualization, point-in-time FlashCopy, disk mirroring, built-in migration capability, and long-distance synchronous and asynchronous replication.

- My New Book is Now Available!
Finally, the various "internal NDA" that kept me from publishing this sooner have expired, so now I have the long-awaited [Inside System Storage: Volume II], documenting IBM's transformation in its storage strategy, including behind-the-scenes commentary about IBM's acquisitions of XIV and Diligent. Available initially in paperback form. I am still working on the hard cover and eBook editions.
For those who have not yet read my first book, Inside System Storage: Volume I, it is still available from my publisher Lulu, in [hard cover], [paperback] and [eBook] editions.
- IBM System Storage DS8800
A lesson IBM learned long ago was not to make radical changes to high-end disk systems, as clients who run mission-critical applications are more concerned about reliability, availability and serviceability than they are performance or functionality. Shipping any product before it was ready meant painfully having to fix the problems in the field instead.
(EMC apparently is learning this same lesson now with their VMAX disk system. Their Engenuity code from Symmetrix DMX4 was ported over to new CLARiiON-based hardware. With several hundred boxes in the field, they have already racked up over 150 severity 1 problems, roughly half of these resulted in data loss or unavailability issues. For the sake of our mutual clients that have both IBM servers and EMC disk, I hope they get their act together soon.)
To avoid this, IBM made incremental changes to the successful design and architecture of its predecessors. The new DS8800 shares 85 percent of the stable microcode from the DS8700 system. Functions like Metro Mirror, Global Mirror, and Metro/Global Mirror, are compatible with all of the previous models of the DS8000 series, as well as previous models of the IBM Enterprise Storage Server (ESS) line.
The previous models of DS8000 series were designed to take in cold air from both front and back, and route the hot air out the top, known as chimney design. However, many companies are re-arranging their data centers into separate cold aisles and hot aisles. The new DS8800 has front-to-back cooling to help accommodate this design.
My colleague Curtis Neal would call the rest of this a "BFD" announcement, which of course stands for "Bigger, Faster and Denser". The new DS8800 scales-up to more drives than its DS8700 predecessor, and can scale-out from a single-frame 2-way system to a multi-frame 4-way system. IBM has upgraded to faster 5GHz POWER6+ processors, with dual-core 8 Gbps FC and FICON host adapters, 8 Gbps device adapters, and 6 Gbps SAS connectivity to smaller form factor (SFF) 2.5-inch SAS drives. IBM Easy Tier will provide sub-LUN automated tiering between Solid-State Drives and spinning disk. The denser packaging with SFF drives means that we can pack over 1000 drives in only three frames, compared to five frames required for the DS8700.

- IBM System Storage SAN Volume Controller v6.1
The [IBM System Storage SAN Volume Controller] software release v6.1 brings Easy Tier sub-LUN automated tiering to the rest of the world. IBM Easy Tier moves the hottest, most active extents up to Solid-State Drives (SSD) and moves the coldest, least active down to spinning disk. This works whether the SSD is inside the SVC 2145-CF8 nodes, or in the managed disk pool.
Tired of waiting for EMC to finally deliver FAST v2 for your VMAX? It has been 18 months since they first announced that someday they would have sub-LUN automatic tiering. What is taking them so long? Why not virtualize your VMAX with SVC, and you can have it sooner!
SVC 6.1 also upgrades to a sexy new web-based GUI, which like the one for the IBM Storwize V7000, is based on the latest HTML5 and dojo widget standards. Inspired by the popular GUI from the IBM XIV Storage System, this GUI has greatly improved ease-of-use.
