Normally, IBM has its announcements on Tuesdays, but this week it was on Monday!
I am here in New York City, at the Kaufmann Theater of the American Museum of Natural History, for the
[IBM Storage Innovation Executive Summit]. We have about 250 clients here, as well as many bloggers and storage analysts.
My day started out being interviewed by Lynda from Stratecast, a division of [Frost & Sullivan]. This interview will be part of a video series that Stratecast is doing about the storage industry.
(About the venue: American Museum of Natural History was built in 1869. It was featured in the film "Night at the Museum". In keeping with IBM's focus on scalability and preservation, the museum here boasts skeletons of the largest dinosaurs. The five-story building takes up several city blocks, and the Kaufmann theater is buried deep in the bottom level, well shielded from cell phone or Wi-Fi signals allowing me to focus on taking notes the traditional way, with pen and paper.)
Deon Newman, IBM VP of Marketing for Northa America, was our Master of Ceremonies. Today would be filled with market insight, best practices, thought leadership, and testimonials of powerful results.
This is my first in a series of blog posts on this event.
- Information Explosion on a Smarter Planet
Bridget van Kralingen, IBM General Manager for North America, indicated that storage is finally having its day in the sun, moving from the "back office" to the "front office". According to Google's Eric Schmidt, we now create, capture and replicate more date in two days than all of the information recorded from the dawn of time to the year 2003.
1928: IBM's innovative 80-column punch card stored nearly twice as much as its 50-column predecessor.
1947: Bing Crosby decided to do his radio show by recording it at his convenience on magnetic tape, rather than doing it live. This was the motivation for IBM researches to investigate tape media, delivering the first commercial tape drive in 1952. One tape reel could hold the equivalent of 30,000 punch cards.
1956: the IBM RAMAC mainframe was the first computer to access data randomly with an externally-attached disk system, the "350 Disk Unit", which stored 5 million 7-bit characters (about 5MB) and weighed over 500 pounds. Compare that today's cell phone that can store several GB of data in a handheld device.
1978: IBM invented Redundant Array of Independent Disks (RAID) through a collaboration with University of Berkeley.
1993: IBM introduces the [IBM 9337 Disk Storage Array], the first external disk storage system for distributed operating systems. This was based on the Serial Storage Architecture [SSA] protocol.
1995: IBM launches products that support Storage Area Networks (SAN), based on the Fibre Channel Protocol. IBM's internal codenames for disk products were all names of sharks, and so our internal mantra was that a healthy storage diet was comprised of "Plenty of Fish and Fibre".
2010: IBM ships Easy Tier, the world's easiest-to-use sub-LUN automated tiering capability, for the IBM System Storage DS8700 disk system.
Storage is growing (in capacity) at 40 percent per year, but IT budgets are only growing (in dollars) by a measly 1 to 5 percent. She cited the success at [Sprint], presented at the October 2010 launch. By combining IBM SAN Volume Controller with a three-tier storage architecture, Sprint lowered their raw capacity from 10PB to 8.4PB, increasing utilization from 35 to 78 percent. This involved shrinking from six storage vendors to three, and reducing total number of disk arrays from 166 down to 96. The resulting system has only 38 percent of their data on their most expensive Tier-1 storage, the rest is now living on less expensive Tier-2 and Tier-3 storage.
Companies are entering the era of Big Data with an insatiable appetite for collecting and analyzing data for marketplace insights. IBM [InfoSphere BigInsights], based on the Apache Hadoop, has helped customers make sense of it all. Innovative technology, expertise and marketplace insight will provide the competitive path forward in the coming decade.
- Storage Challenges and Opportunities in 2011 and Beyond
I always enjoy hearing Stan Zaffos, Gartner Research VP, present at the annual [Data Center Conference] in Las Vegas every December. His analysis and research focuses on storage systems and emerging storage technologies.
Stan provided his perspective on the storage industry. He suggested a top-down approach, based on the market trends that Gartner is closely monitoring. He suggests focusing heavily on managing data growth, using SLAs to improve efficiency, and to follow Gartner's recommended actions. His statement, "If something is not sustainable, then it is unsustainable." resonated well with the audience. His key three points:
- Design to meet but not exceed Service Level Agreements (SLAs)
- Re-evaluate your ratio of SAN versus NAS based on growth of unstructured data content,
- Explore the variety of Cloud options available.
Those of us who have been in this business a long time recognize that the problems haven't changed, just the dimensions. When in the past three decades were IT budgets generous and plentiful? When was there more than enough IT staff to handle all the requests in a timely manner? When hasn't there been a period of information growth? Gartner's analysis external control block (RAID protected disk systems) is growing revenue at 8.7 percent. Raw TBs of disk capacity is growing at 55 percent, and expected to be 100 Exabytes by 2015.
SAN has four times more revenue than NAS today, but NAS is growing faster. NAS was only 9 percent marketshare in 2010, but is projected to grow to 32 percent by 2015. SAN can offer higher price/performance for traditional OLTP and database workloads, but NAS is better suited for unstructured data, backups and archives, assisted by storage efficiency features like real-time compression and data deduplication. Which industries create the most unstructured data? The ones involved in filling out forms! This includes government, insurance agencies, manufacturing, mining and pharmaceuticals.
The phrase "good enough" should no longer be considered an insult. Too often IT departments design solutions that far exceed negotiated Service Level Agreements (SLAs), and they should instead focus on just meeting them instead. Modular storage systems are often sufficient for most workloads. Slower 7200RPM SATA disks can be one third the price of faster 15K RPM Fibre Channel drives, and often sufficient performance for the tasks required. Unified storage, such as IBM N series, can help simplify capacity planning, as storage can be re-purposed if different workloads grow at different rates. The key is to focus on meeting SLAs based on the price-vs-risk factor. Take a minimalist approach with fewer SLAs, fewer management classes, and fewer storage vendors.
Stan suggests a two-pronged approach: Capacity management through content analytics and classification, and Efficient Utilization through Thin Provisioning, storage virtualization, Quality of Service (QoS), compression and deduplication capabilities. This features will be ubiquitous by 2013. If you are worried that these technologies mean more information packed onto fewer devices, Stan's response was "If it's not there, it can't break." Storing data on fewer disks or tape cartridges means less chance something will fail.
Stan feels IT shops using Thin Provisioning should continue to charge their end-users on what they ask for (the full allocation request) rather than what the thin-provisioned amount actually is on the storage devices themselves. For example, if someone asks for 100GB LUN to be allocated to their system, but this only takes up 30GB of actual data space, chargeback the full 100GB!
It can take five years for new technology to get 50 percent adopted. The Romans took eight years to build the [Colosseum]. His research on "network convergence" found that 42 percent planned to use iSCSI, 32 percent Fibre Channel over Ethernet (FCoE) or other Top-of-Rack(TOR) converged switches, and 16 percent looking for full convergence of servers, switches and storage. Features like IBM Easy Tier automatic sub-LUN tiering were introduced later, and so have not been adopted as widely as other features like Thin Provisioning that have been around since the 1990's IBM RAMAC Virtual Array.
Stan felt that Public and Private clouds were two different approaches. Public clouds offer reservation-less provisioning. Private clouds offer improved agility, but can be more complex to set up, and has the risk of idle capacity similar to traditional IT datacenter deployments. Storage and File virtualization should be considered a pre-req for adopting Cloud technologies.
Storage IT teams need to adopt more than just technical skills. They need to learn about legal and government regulatory compliance issues, financial considerations, and would even benefit doing some "marketing". Why marketing? Because often IT departments need end-users to change their attitudes and behaviours, and this can be accomplished through internal marketing campaigns.
This certainly was a great way to start the day!

Every January, we look back into the past as well as look into the future for trends to watch for the upcoming year. Ray Lucchesi of Silverton Consulting has a great post looking back at the [Top 10 storage technologies over the last decade]. I am glad to see that IBM has been involved with and instrumental in all ten technologies.
Looking into the future, Mark Cox of eChannel has an article [Storage Trends to Watch in 2011], based on his interviews with two fellow IBM executives: Steve Wojtowecz, VP of storage software development, and Clod Barrera, distinguished engineer and CTO for storage. Let's review the four key trends:
- Cloud Storage and Cloud Computing
No question: Cloud Computing will be the battleground of the IT industry this decade. I am amused by the latest spate of Microsoft commercials where problems are solved with someone saying "...to the cloud". Riding on the coat tails of this is "Cloud Storage", the ability to store data across an Internet Protocol (IP) network, such as 10GbE Ethernet, in support of Cloud Computing applications. Cloud Storage protocols in the running include NFS, CIFS, iSCSI and FCoE.
Mark writes "..vendors who aren't investing in cloud storage solutions will fall behind the curve."
- Economic Downturn forces Innovation
The old British adage applies: "Necessity is the mother of invention." The status quo won't do. In these difficult economic times, IT departments are running on constrained budgets and staff. This forces people to evaluate innovative technologies for storage efficiency like real-time compression and data deduplication to make better use of what they currently have. It also is forcing people to take a "good enough" attitude, instead of paying premium prices for best-of-breed they don't really need and can't really afford.
- IT Service Management
Companies are getting away from managing individual pieces of IT kit, and are focusing instead on the delivery of information, from the magnetic surface of disk and tape media, to the eyes and ears of the end users. The deployment mix of private, hybrid and public clouds makes this even more important to measure and manage IT as a set of services that are delivered to the business. IT Service Management software can be the glue, helping companies implement ITIL v3 best practices and management disciplines.
- Smarter Data Placement
A recent survey by "The Info Pro" analysts indicates that "managing storage growth" is considered more critical than "managing storage costs" or "managing storage complexity".
This tells me that companies are willing to spend a bit extra to deploy a tiered information infrastructure if it will help them manage storage growth, which typically ranges around 40 to 60 percent per year. While I have discussed the concept of "Information Lifecycle Management" (ILM), for the past four years on this blog, I am glad to see it has gone mainstream, helped in part with automated storage tiering features like IBM System Storage Easy Tier feature on the IBM DS8000, SAN Volume Controller and Storwize V7000 disk systems. Not all data is created equal, so the smart placement of data, based on the business value of the information contained, makes a lot of sense.
These trends are influencing what solutions the various different vendors will offer, and will influence what companies purchase and deploy.

For most of us in the United States, it is cold out there, so you better "bundle up!"
Today, IBM announces the [IBM Storwize Rapid Application Storage] bundle, an integrated solution that improves storage efficiency and application availability. It comes in two offerings:
The "Basic" offering includes a single IBM Storwize V7000 controller enclosure, and three year warranty package that includes software licenses for IBM Tivoli Storage FlashCopy Manager (FCM) and IBM Tivoli Storage Productivity Center for Disk - Midrange Edition (MRE). Planning, configuration and testing services for the software are included and can be performed by either IBM or an IBM Business Partner.
The "Standard" offering allows for multiple IBM Storwize V7000 enclosures, provides three year warranty package for the FCM and MRE software, and includes implementation services for both the hardware and the software components. These services can be performed by IBM or an IBM Business Partner.
Why bundle? Here are the key advantages for these offerings:
- Increased storage utilization! First introduced in 2003, IBM SAN Volume Controller is able to improve storage utilization by 30 percent through virtualization and thin provisioning. IBM Storwize V7000 carries on this tradition. Space-efficient FlashCopy is included in this bundle at no additional charge and can reduce the amount of storage normally required for snapshots by 75 percent or more. IBM Tivoli Storage FlashCopy Manager can manage these FlashCopy targets easily.
- Improved storage administrator productivity! The new IBM Storwize V7000 Graphical User Interface can help improve administrator productivity up to 2 times compared to other midrange disk solutions. The IBM Tivoli Storage Productivity Center for Disk - Midrange Edition provides real-time performance monitoring for faster analysis time.
- Increased application performance! This bundle includes the "Easy Tier" feature at no additional charge. Easy Tier is IBM's implementation of sub-LUN automated tiering between Solid-State Drives (SSD) and spinning disk. Easy Tier can help improve application throughput up to 3 times, and improve response time up to 60 percent. Easy Tier can help meet or exceed application performance levels with its internal "hot spot" analytics.
- Increased application availability! IBM Tivoli Storage FlashCopy Manager provides easy integration with existing applications like SAP, Microsoft Exchange, IBM DB2, Oracle, and Microsoft SQL Server. Reduce application downtime to just seconds with backups and restores using FlashCopy. The built-in online migration feature, included at no additional charge, allows you to seamlessly migrate data from your old disk to the new IBM Storwize V7000.
- Significantly reduced implementation time! This bundle will help you cut implementation time in half, with little or no impact to storage administrator staff. This will help you realize your return on investment (ROI) much sooner.

Continuing my post-week coverage of the [Data Center 2010 conference], Wendesday afternoon included a mix of sessions that covered storage and servers.
- Enabling 5x Storage Efficiency
Steve Kenniston, who now works for IBM from recent acquisition of Storwize Inc, presented IBM's new Real-Time Compression appliance. There are two appliances, one handles 1 GbE networks, and the other supports mixed 1GbE/10GbE connectivity. Files are compressed in real-time with no impact to performance, and in some cases can improve performance because there is less data written to back-end NAS devices. The appliance is not limited to IBM's N series and NetApp, but is vendor-agnostic. IBM is qualifying the solution with other NAS devices in the market. The compression can compress up to 80 percent, providing a 5x storage efficiency.
- Townhall - Storage
The townhall was a Q&A session to ask the analysts their thoughts on Storage. Here I will present the answer from the analyst, and then my own commentary.
Are there any gotchas deploying Automated Storage Tiering?
Analyst: you need to fully understand your workload before investing any money into expensive Solid-State Drives (SSD).
Commentary: IBM offers Easy Tier for the IBM DS8000, SAN Volume Controller, and Storwize V7000 disk systems. Before buying any SSD, these systems will measure the workload activity and IBM offers the Storage Tier Advisory Tool (STAT) that can help identify how much SSD will benefit each workload. If you don't have these specific storage devices, IBM Tivoli Storage Productivity Center for Disk can help identify disk performance to determine if SSD is cost-justified.
Wouldn't it be simpler to just have separate storage arrays for different performance levels?
Analyst: No, because that would complicate BC/DR planning, as many storage devices do not coordinate consistency group processing from one array to another.
Commentary: IBM DS8000, SAN Volume Controller and Storwize V7000 disk systems support consistency groups across storage arrays, for those customers that want to take advantage of lower cost disk tiers on separate lower cost storage devices.
Can storage virtualization play a role in private cloud deployments?
Analyst: Yes, by definition, but today's storage virtualization products don't work with public cloud storage providers. None of the major public cloud providers use storage virtualization.
Commentary: IBM uses storage virtualization for its public cloud offerings, but the question was about private cloud deployments. IBM CloudBurst integrated private cloud stack supports the IBM SAN Volume Controller which makes it easy for storage to be provisioned in the self-service catalog.
Can you suggest one thing we can do Monday when we get back to the office?
Analyst: Create a team to develop a storage strategy and plan, based on input from your end-users.
Commentary: Put IBM on your short list for your next disk, tape or storage software purchase decision. Visit
[ibm.com/storage] to re-discover all of IBM's storage offerings.
What is the future of Fibre Channel?
Analyst 1: Fibre Channel is still growing, will go from 8Gbps to 16Gbps, the transition to Ethernet is slow, so FC will remain the dominant protocol through year 2014.
Analyst 2: Fibre Channel will still be around, but NAS, iSCSI and FCoE are all growing at a faster pace. Fibre Channel will only be dominant in the largest of data centers.
Commentary: Ask a vague question, get a vague answer. Fibre Channel will still be around for the next five years.
However, SAN administrators might want to investigate Ethernet-based approaches like NAS, iSCSI and FCoE where appropriate, and start beefing up their Ethernet skills.
- Will Linux become the Next UNIX?
Linux in your datacenter is inevitable. In the past, Linux was limited to x86 architectures, and UNIX operating systems ran on specialized CPU architectures: IBM AIX on POWER7, Solaris on SPARC, HP-UX on PA-RISC and Itanium, and IBM z/OS on System z Architecture, to name a few. But today, Linux now runs on many of these other CPU chipsets as well.
Two common workloads, Web/App serving and DBMS, are shifting from UNIX to Linux. Linux Reliability, Availability and Serviceability (RAS) is approaching the levels of UNIX. Linux has been a mixed blessing for UNIX vendors, with x86 server margins shrinking, but the high-margin UNIX market has shrunk 25 percent in the past three years.
UNIX vendors must make the "mainframe argument" that their flavor of UNIX is more resilient than any OS that runs on Intel or AMD x86 chipsets. In 2008, Sun Solaris was the number #1 UNIX, but today, it is IBM AIX with 40 percent marketshare. Meanwhile HP has focused on extending its Windows/x86 lead with a partnership with Microsoft.
The analyst asks "Are the three UNIX vendors in it for the long haul, or are they planning graceful exits?" The four options for each vendor are:
- Milk it as it declines
- Accelerate the decline by focusing elsewhere
- Impede the market to protect margins
- Re-energize UNIX base through added value
Here is the analyst's view on each UNIX vendor.
IBM AIX now owns 40 percent marketshare of the UNIX market. While the POWER7 chipset supports multiple operating systems, IBM has not been able to get an ecosystem to adopt Linux-on-POWER. The "Other" includes z/OS, IBM i, and other x86-based OS.
HP has multi-OS Itanium from Intel, but is moving to Multi-OS blades instead. Their "x86 plus HP-UX" strategy is a two-pronged attack against IBM AIX and z/OS. Intel Nehalem chipset is approaching the RAS of Itanium, making the "mainframe argument" more difficult for HP-UX.
Before Oracle acquired Sun Microsystems, Oracle was focused on Linux as a UNIX replacement. After the acquisition, they now claim to support Linux and Solaris equally. They are now focused on trying to protect their rapidly declining install base by keeping IBM and HP out. They will work hard to differentiate Solaris as having "secret sauce" that is not in Linux. They will continue to compete head-on against Red Hat Linux.
An interactive poll of the audience indicated that the most strategic Linux/UNIX platform over the next next five years was Red Hat Linux. This beat out AIX, Solaris and HP-UX, as well as all of the other distributions of Linux.
The rooms emptied quickly after the last session, as everyone wanted to get to the "Hospitality Suites".

The client that bought these dozen IBM System Storage DS8800 disk systems also bought three DS8700 systems.
Governor's Celebration of Innovation [GCOI] is an annual awards gala, with attendees who include technologists, corporate executives, entrepreneurs, investors, and policymakers. Last week, IBM was awarded "Innovator of the Year" in the Large Company category for its Easy Tier feature of the IBM DS8700 that allows optimal use of Solid-State Drives through sub-LUN automatic movement of data. IBM's Long Term File System (LTFS) was also a finalist under consideration.
The award was presented to Cindy Grossman, IBM VP and Senior Location Executive for Tucson. Joining her were Dr. Krishna Nathan, Ed Childers, Glen Jaquette, Vincent Hsu, Rick Krebsbach, Gene Leo, Denise Lopez, Hironobu Nagura, Calline Sanchez, Johnny Smith, and Dr. Cheng-Chung Song.
