Well, it's Tuesday, in the United States at least, and you know what that means... IBM Announcements! I am actually down under in Sydney, Australia, and it is Wednesday already as I write this. I feel like a time traveler.
IBM announces their latest disk system, the [IBM System Storage DCS3700], designed for high-performance computing (HPC), business analytics, video broadcasting, and other sequential workloads. The "DCS" stands for Deep Computing Storage. IBM already has the DCS9900 for large enterprise deployments, so this smaller DCS3700 is targeted for midrange deployments.
In a compact 4U package, the DCS3700 packs dual active-active controllers and up to 60 disk drives. The controller drawer can support two additional expansion drawers, of 60 drives each in 4U drawers, for a maximum total of 180 drives in 12U of rack space. Packed with "green" 7200RPM energy-efficient 2TB drives, a system can have up to a 360TB raw capacity. The system supports RAID levels 0, 1, 3, 5, 6, and 10.
The system comes with the latest 6Gbps SAS connections for host attachment, but you can choose 8Gbps Fibre Channel Protocol (FCP) instead, allowing the DCS3700 to be managed by SVC or Storwize V7000.
IBM introduced the Linear Tape File System last year, which I explained in my post [IBM Celebrates 10 Year Anniversary for LTO tape], and released it as open source to the rest of the Linear Tape Open [LTO] Consortium so that the entire planet can benefit from IBM's innovation. IBM presented a technology demonstration of its Linear Tape File System - Library Edition at the NAB conference, showing how this new IBM library offering of the file system can put mass archives of rich media video content at the users fingertips with the ease of library automation.
From left to right, here is Atsushi Nagaishi (Toshiba) and Shinobu Fujihara (IBM). Fujihara-san is from IBM's Yamato lab in Japan where some of the LTFS development was done. The Yamato Lab was not damaged by the [Earthquakes in Japan].
With the capabilities of LTFS, IBM has introduced an entirely new role for tape, as an attractive high capacity, easy to use, low cost and shareable storage media. LTFS can make tape usable in a fashion like removable external disk, a giant alternative to floppy diskettes, DVD-RW and USB memory sticks with directory tree access and file-level drag-and-drop capability. LTFS can allow the for passing of information around from one system or employee to another. And as for high video storage capacity, a 1.5TB LTO-5 cartridge can hold about 50 hours of XDCAM HD video!

IBM was once again #1 leader in Tape worldwide for the year 2010. With this exciting new win, tape is not just for backup and archive anymore!
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.
Optimizing Storage Infrastructure for Growth and Innovation
This session started off with my former boss, Brian Truskowski, IBM General Manager of System Storage and Networking.
We've come a long way in storage. In 1973, the "Winchester Drive" was named after the famous Winchester 3030 rifle. The disk drive was planning to have two 30MB platters, hence the name. When it finally launched, it would have two 35MB platters, for a total raw capacity of 70MB.
Today, IBM announced the verison 6.2 of SAN Volume Controller with support for 10GbE iSCSI. Since 2003, IBM has sold over 30,000 SAN Volume Controllers. An SVC cluster can now manage up to 32PB of disk storage.
IBM also announced new 4TB tape drive (TS1140), LTFS Library Edition, the TS3500 Library Connector, improved TS7600 and TS7700 virtual tape libraries, enhanced Information Archive for email, files and eDiscovery, new Storwize V7000 hardware, new Storwize Rapid Application bundles, new firmware for SONAS and DS8000 disk systems, and Real-Time Compression support for EMC disk systems. I plan to cover each of these in follow-on posts, but if you can't wait, here are [links to all the announcements].
Customer Testimonial - CenterPoint Energy
"CenterPoint is transforming its business from being an energy distribution company that uses technology, to a technology company that distributes energy."
-- Dr. Steve Pratt, CTO of CenterPoint Energy
The next speaker was Dr. Steve Pratt is CTO of [CenterPoint Energy]. CenterPoint is 110 years old (older than IBM!) energy company that is involved in electricity, gasoline distribution, and natural gas pipeline. CenterPoint serves Houston, Texas (the fourth largest city in the USA) and surrounding area.
CenterPoint are transforming to a Smart Grid involving smart meters, and this requires the best IT infrastructure you can buy, including IBM DS8000, XIV and SAN Volume Controller disk systems, IBM Smart Analytics System, Stream Analytics, IBM Virtual Tape Library, IBM Tivoli Storage Manager, and IBM Tivoli Storage Productivity Center.
Dr. Pratt has seen the transition of information over the years:
Data Structure, deciding how to code data to record it in a structured manner
Information Reporting, reporting to upper management what happened
Intelligence Aggregation, finding patterns and insight from the data
Predictive Analytics, monitoring real-time data to take pro-active steps
Autonomics, where automation and predictive analysis allows the system to manage itself
What does the transition to a Smart Grid mean for their storage environment? They will go from 80,000 meter reads, to 230,400,000 reads per day. Ingestion of this will go from MB/day to GB/sec. Reporting will transition to real-time analytics.
Dr. Pratt prefers to avoid trade-offs. Don't lose something to get something else. He also feels that language of the IT department can help. For example, he uses "Factor" like 25x rather than percent reduction (96 percent reduced). He feels this communicates the actual results more effectively.
Today's smarter consumers are driving the need for smarter technologies. Individual consumers and small businesses can make use of intelligent meters to help reduce their energy costs. Everything from smart cars to smart grids will need real-time analytics to deal with the millions of events that occur every day.
IBM's Data Protection and Retention Story
Brian Truskowski came back to provide the latest IBM messaging for Data Protection and Retention (DP&R). The key themes were:
Stop storing so much
Store more with what's on the floor
Move data to the right place
IBM announced today that the IBM Real-Time Compression Appliances now support EMC gear, such as EMC Celerra. While some of the EMC equipment have built-in compression features, these often come at a cost of performance degradation. Instead, the IBM Real-Time compression can offer improved performance as well as 3x to 5x reduction in storage capacity.
OVer 70 percent of data on disk has not be accessed in the last 90 days. IBM Easy Tier on the DS8700 and DS8800 now support FC-to-SATA automated tiering.
IBM is projecting that backup and archive storage will grow at over 50 percent per year. To help address this, IBM is launching a new "Storage Infrastructure Optimization" assessment. All attendees at today's summit are eligible for a free assessment.
Analytics are increasing the value of information, and making it more accessible to the average knowledge worker. The cost of losing data, as well as the effort spent searching for information, has skyrocketed. Users have grown to expect 100 percent uptime availability.
An analysis of IT environments found that only 55 percent was spent on revenue-producing workloads. The remaining 45 percent was spent on Data Protection and Retenion. That means that for every IT dollar spent on projects to generate revenue, you are spending another 90 cents to protect it. Imagine spending 90 percent of your house payments for homeowners' insurance, or 90 percent of your car's purchase price for car insurance.
IBM has organized its solutions into three categories:
Hyper-Efficient Backup and Recovery
Continuous Data Availability
What would it mean to your business if you could shift some of the money spent on DP&R over to revenue-producing projects instead? That was the teaser question posed at the end of these morning sessions for us to discuss during lunch.
During lunch, people were able to take a look at our solutions. Here are Dan Thompson and Brett Cooper striking a pose.
Hyper-Efficient Backup and Recovery
The afternoon was kicked off by Dr. Daniel Sabbah, IBM General Manager of Tivoli software. He started with some shocking statistics: 42 percent of small companies have experienced data loss, 32 percent have lost data forever. IBM has a solution that offers "Unified Recovery Management". This involves a combination of periodic backups, frequent snapshots, and remote mirroring.
IBM Tivoli Storage Manager (TSM) was introduced in 1993, and was the first backup software solution to support backup to disk storage pools. Today, TSM is now also part of Cloud Computing services, including IBM Information Protection Services. IBM announced today a new bundle called IBM Storwize Rapid Application Backup, which combines IBM Storwize V7000 midrange disk system, Tivoli FlashCopy Manager, implementation services, with a full three-year hardware and software warranty. This could be used, for example, to protect a Microsoft Exchange email system with 9000 mailboxes.
IBM also announced that its TS7600 ProtecTIER data deduplication solutions have been enhanced to support many-to-many bi-direction remote mirroring. Last year, University of Pittsburgh Medical Center (UPMC) reported that they were average 24x data deduplication factor in their environment using IBM ProtecTIER.
"You are out of your mind if you think you can live without tape!"
-- Dick Crosby, Director of System Administration, Estes
The new IBM TS1140 enterprise class tape drive process 2.3 TB per hour, and provides a density of 1.2 PB per square foot. The new 3599 tape media can hold 4TB of data uncompressed, which could hold up to 10TB at a 2.5x compression ratio.
The United States Golfers Association [USGA] uses IBM's backup cloud, which manages over 100PB of data from 750 locations across five continents.
Customer Testimonial - Graybar
Randy Miller, Manager of Technical System Administration at Graybar, provided the next client testimonial. Graybar is an employee-owned company focused on supply-chain management, serving as a distributor for electical, lighting, security, power and cooling equipment.
Their problem was that they had 240 different locations, and expecting local staff to handle tape backups was not working out well. They centralized their backups to their main data center. In the event that a system fails in one of their many remote locations, they can rebuild a new machine at their main data center across high-speed LAN, and then ship overnight to the remote location. The result, the remote location has a system up and running by 10:30am, faster than they would have had from local staff trying to figure out how to recover from tape. In effect, Graybar had implemented a "private cloud" for backup in the 1990s, long before the concept was "cool" or "popular".
In 2001, they had an 18TB SAP ERP application data repository. To back this up, they took it down for 1 minute per day, six days a week, and 15 minutes down on Sundays. The result was less than 99.8 percent availability. To fix this, they switched to XIV, and use Snapshots that are non-disruptive and do not impact application performance.
Over 85 percent of the servers at Graybar are virtualized.
Their next challenge is Disaster Recovery. Currently, they have two datacenters, one in St. Louis and the other in Kansas City. However, in the aftermath of Japan's earthquakes, they realize there is a nuclear power plan between their two locations, so a single incident could impact both data centers. They are working with IBM, their trusted advisors, to investigate a three-site solution.
This week, May 15-22, I am in Auckland, New Zealand teaching IBM Storage Top Gun sales class. Next week, I will be in Sydney, Australia.
