Well, it's Wednesday! Normally, IBM makes its announcements on Tuesday's, but this week that landed on the 13th, and some people are superstitious, so we pushed it back to today. Fellow IBM master inventory Barry Whyte starts the first in a series of posts with: New SVC v5 CF8 node with native SSD support.
There are really two separate items being announced for the IBM System Storage SAN Volume Controller (SVC):
SVC v5 software
The software moves from a 32-bit kernel to a 64-bit kernel. Fortunately, IBM had the foresight to know that would happen back in 2005, so models 8F2, 8F4 and 8G4 can be upgrade to this new software level and gain new functionality. This is because these models have 64-bit capable processors. Those with six-year-old 4F2 will continue to run on SVC 4.3.1, but should consider it's about time to upgrade soon.
New 2145-CF8 model
The CF8 is based on the IBM System x 3550M2. Each node can have up to 4 Solid-State Drives (SSD) that can be treated as SVC Managed Disk Groups. Virtual disks can be easily migrated from hard disk drives (HDD) over to SSD, processed, and then move them back to HDD. By treating the SSD as managed disks, rather than an extension of the cache, we are able to support all of the features and functions in a seamless manner.
As Barry says, IBM has been working on this for quite a while, and based on initial responses looks to be quite successful in the market!
(Note: I have been informed that this week the U.S. Federal Trade Commission has [announced an update] to its
[16 CFR Part 255: Guides Concerning the Use of Endorsements and Testimonials in Advertising]. As if it were not obvious enough already, I must emphasize that I work for IBM, IBM provides me all the equipment and related documentation that I need for me to blog about IBM solutions, and that I am paid to blog as part of my job description. Both my boss and I agree I am not paid enough, but that is another matter. Beginning December 1, 2009, all positive mentions of IBM products, solutions and services on this blog might be considered a "celebrity endorsement" by the FTC and others under these new guidelines. Negative mentions of IBM products are probably typos.)
At a conference once, a presenter discussing tips and techniques about public speaking told everyone to be
aware that everyone in the audience is "tuned into radio station WIIFM" (What's In It For Me). If a member of the audience cannot figure out why the information being presented is relevant to them individually, they may not pay attention for long. Likewise, when it comes to archiving data for long term retention, I think we have many people are tuned into KEFM (the Keep Everything Forever methodology). Two classic articles from Drew Robb on the subject are [Can Data Ever Be Deleted?] and [Experts Question 'Keep Everything' Philosophy].
(Note: For those of my readers who do not live in the US, most radio stations start with
the letter "K" if they are on the left half of the country, and "W" if they are on the right half. See
Thomas H. White's [Early Radio History] to learn more.)
Contrary to popular belief, IBM would rather have their clients implement a viable archive strategy than just mindlessly buying more disk and tape for a "Keep Everything Forever" methodology. Keeping all information around forever can be a liability, as data that you store can be used against you in a court of law. It can also make it difficult to find the information that you do need, because the sheer volume of information to sort through makes the process more time consuming.
The problem with most archive storage solutions is that they are inflexible, treating all data the same under a common set of rules. The IBM Information Archive is different. You can have up to three separate "collections".
Each collection can have its own set of policies and rules. You can have a collection that is locked down
for compliance with full Non-Erasable, Non-Rewriteable (NENR) enforcement, and another collection that allows
full read/write/delete capability.
Each collection can consist of either files or objects. Unlike other storage devices that force you to convert files into objects, or objects into files for their own benefit.
IBM Information Archive is scalable enough to support up to a billion of either files or objects per collection.
Each collection can span storage tiers, even across disk and tape resources.
Object collections are accessed using IBM System Storage Archive Manager (SSAM) application programming interface (API). People who use IBM Tivoli Storage Manager (TSM) archive or IBM System Storage DR550 are already familiar with this interface. An object can represent the archived slice of a repository, a set of rows from a database, a collection of emails from an individual mailbox user, etc.
File collections can be used for any type of data you would store on a NAS device. This includes databases, email repositories, static Web pages, seismic data, user documents, spreadsheets, presentations, medical images, photos, videos, and so on.
The IBM Information Archive solution was designed to work with a variety of Enterprise Content Management (ECM) software, and is part of the overall IBM Smart Archive strategy.
Well, it's Tuesday, and that means IBM announcements! Today is bigger, as there are a lot of Dynamic Infrastructure announcements throughout the company with a common theme, cloud computing and smart business systems that support the new way of doing things. Today, IBM announced its new "IBM Smart Archive" strategy that integrates software, storage, servers and services into solutions that help meet the challenges of today and tomorrow. IBM has been spending the past few years working across its various divisions and acquisitions to ensure that our clients have complete end-to-end solutions.
IBM is introducing new "Smart Business Systems" that can be used on-premises for private-cloud configurations, as well as by cloud-computing companies to offer IT as a service.
IBM [Information Archive] is the first to be unveiled, a disk-only or blended disk-and-tape Information Infrastructure solution that offers a "unified storage" approach with amazing flexibility for dealing with various archive requirements:
For those with applications using the IBM Tivoli Storage Manager (TSM) or IBM System Storage Archive Manager (SSAM) API of the IBM System Storage DR550 data retention solution, the Information Archive will provide a direct migration, supporting this API for existing applications.
For those with IBM N series using SnapLock or the File System Gateway of the DR550, the Information Archive will support various NAS protocols, deployed in stages, including NFS, CIFS, HTTP and FTP access, with Non-Erasable, Non-Rewriteable (NENR) enforcement that are compatible with current IBM N series SnapLock usage.
For those using NAS devices with PACS applications to store X-rays and other medical images, the Information Archive will provide similar NAS protocol interfaces. Information Archive will support both read-only data such as X-rays, as well as read/write data such as Electronic Medical Records.
Information Archive is not just for compliance data that was previously sent to WORM optical media. Instead, it can handle all kinds of data, rewriteable data, read-only data, and data that needs to be locked down for tamper protection. It can handle structured databases, emails, videos and unstructured files, as well as objects stored through the SSAM API.
The Information Archive has all the server, storage and software integrated together into a single machine type/model number. It is based on IBM's General Parallel File System (GPFS) to provide incredible scalability, the same clustered file system used by many of the top 500 supercomputers. Initially, Information Archive will support up to 304TB raw capacity of disk and Petabytes of tape. You can read the [Spec Sheet] for other technical details.
For those who prefer a more "customized" approach, similar to IBM Scale-Out File Services (SoFS), IBM has [Smart Business Storage Cloud]. IBM Global Services can customize a solution that is best for you, using many of the same technologies. In fact, IBM Global Services announced a variety of new cloud-computing services to help enterprises determine the best approach.
In a related announcement, IBM announced [LotusLive iNotes], which you can think of as a "business-ready" version of Google's GoogleApps, Gmail and GoogleCalendar. IBM is focused on security and reliability but leaves out the advertising and data mining that people have been forced to tolerate from consumer-oriented Web 2.0-based solutions. IBM's clients that are already familiar with on-premises version of Lotus Notes will have no trouble using LotusLive iNotes.
There was actually a lot more announced today, which I will try to get to in later posts.
Bruce Allen from BR Allen Associates LLC, an IT technology strategy and consulting firm, has written an excellent 9-page White Paper contrasting IBM and EMC's latest strategies. Here are some key excerpts:
"The term “information infrastructure” is over 40 years old, but its characteristics and requirements in today’s world are quite new indeed. Specifically, federating all storage enterprise wide, consolidating and standardizing onto virtualized, high-capacity media, and enabling dynamic, cloud-ready provisioning are among the major new IT challenges. Moreover, continued explosive storage growth demands that a systematic approach be crafted to address the full spectrum of current and future (information) compliance, availability, retention and security goals. For many customers, this transformation must occur amidst a storage growth rate of 50%-70% CAGR.
...IBM’s Information Infrastructure focus is a core element and foundational pillar in its Dynamic Infrastructure and New Intelligence initiatives, both well defined and tightly coupled to an umbrella vision and strategy called “Smarter Planet.” It is also important to remember that IBM has its own vast, internal infrastructure, and is transforming it in the same manner prescribed to customers. IBM’s increased investment in solution centers and expertise to develop and test drive customer solutions demonstrates its resolve in this area.
...In contrast, storage vendor EMC references information infrastructure as half of its bifurcated strategy,1 with virtualization being the other half. The two are represented by slightly overlapping circles, and interestingly, these two circles essentially mirror the EMC organization. ...Analysis of both the strategy and the organization indicates a continued strong product focus, a stark contrast to IBM’s strategy that puts solutions first and products second.
...IBM’s Information Infrastructure strategy and portfolio takes a more holistic approach and appears to be shifting its own organizations and partners from pure product focus to a true solution orientation that more directly addresses customer needs. ...IBM views these elements as integral to any information-led transformation, but its competitors fall well short in this arena.
...As a system vendor, IBM clearly has a more in-depth set of offerings and a more elegant strategy and vision for providing a dynamic information environment than its competitors. None of the other system vendors have made the strides, or the investments, that IBM has.
...Because of its size and breadth, IBM uniquely has all of the pieces, and also has a vast information infrastructure of its own to build and manage. IBM often uses its internal systems to showcase new capabilities, as shown in these examples:
In an early cloud computing production pilot, IBM was able to reduce costs by managing more than 92,000 worldwide users with one storage cloud and one delivery team. Lessons learned from this deployment helped IBM establish cloud computing requirements for today’s products and services.
In 2009, IBM deployed a unified, centralized customer support portal for all technical support tools and information. The portal unifies all IBM systems, software, and services support sites, including those from recent acquisitions. By leveraging its own portal, database, and storage technology, IBM was able to consolidate multiple support sites into a single portal. The new portal dramatically simplifies the user experience for clients with multiple IBM products, while helping IBM control infrastructure costs.
...a key difference between IBM and EMC is IBM’s orientation to total-solution provisioning, not just for one application at a time, but for the entire set of infrastructure needs that customers have. To ensure this, a clearly articulated strategy and vision keeps IBM’s focus on the bigger picture as it addresses each customer’s requirements.
...Efforts tied to cloud computing have helped vendor organizations to work together better toward composite and integrated solutions, but the vague specifications and lack of immediate revenue keep most vendor sales organizations focused on their respective products. The only other way to address the challenges of integrating people and technology as described above is to put a clear strategy in place with specific tactical goals and objectives. This is where IBM leads the industry in making demonstrable progress in building solutions that achieve the goals of its dynamic infrastructure model and strategy.
...IBM is in a unique position to deliver and support the full information infrastructure “stack” and address all of its clients’ information-centric challenges. The combination of IBM’s storage technology, information management products, aggressive financing, and best-of-breed integrated services supported by world-class expertise and proven experience, provide the building blocks for the world’s strongest information infrastructure portfolio.
Mr. Allen also discusses the successes of two real client examples, Virginia Commonwealth University Health Systems (VCUHS), and INTTRA, the largest multi-carrier e-commerce platform for the ocean shipping industry.
Well, it's Tuesday, which means IBM Announcements!
We have both disk and tape related announcements today.
2 TB Drives
Yes, they are finally here. IBM now offers [2 TB SATA drives for its IBM System Storage DCS9900 series] disk systems. These are 5400 RPM, slower than traditional 7200 RPM SATA drives. This increases the maximum capacity of a single DCS9900 from 1200 TB to 2400 TB. The DCS9900 is IBM's MAID system (Massive Array of Idle Disk) which allows for drive spin-down to reduce energy costs and is ideal for long term retention of archive data that must remain on disk for High Performance Computing or video streaming.
TS3000 System Console
The TS3000 System Console [provides improved features for service and support] of up to 24 tape library frames or 43 unique tape systems. Tape frames include those of the TS7740, TS7720 and TS7650. Tape systems include TS3500, TS3400 or 3494 libraries as well as stand-alone TS1120 and TS1130 drives. Having the TS3000 System Console in place is a benefit to both IBM and the customer, as it improves IBM's ability to provide service in a more timely manner.
Both announcements are part of IBM's strategy to provide cost-effective, energy-efficient, long-term retention storage for archive data.
I saw this as an opportunity to promote the new IBM Tivoli Storage Manager v6.1 which offers a variety of new scalability features, and continues to provide excellent economies of scale for large deployments, in my post [IBM has scalable backup solutions].
"So does TSM scale? Sure! Just add more servers. But this is not an economy of scale. Nothing gets less expensive as the capacity grows. You get a more or less linear growth of costs that is directly correlated to the growth of primary storage capacity. (Technically, it costs will jump at regular and predictable intervals, by regular and predictable and equal amounts, as you add TSM servers to the infrastructure--but on average it is a direct linear growth. Assuming you are right sized right now, if you were to double your primary storage capacity, you would double the size of the TSM infrastructure, and double your associated costs.)"
I talked about inaccurate vendor FUD in my post [The murals in restaurants], and recently, I saw StorageBod's piece, [FUDdy Waters]. So what would "economies of scale" look like? Using Scott's own words:
Without Economies of Scale
"If it costs you $5 to backup a given amount of data, it probably costs you $50 to back up 10 times that amount of data, and $500 to back up 100 times that amount of data."
With Economies of Scalee
"If anybody can figure out how to get costs down to $40 for 10 times the amount of data, and $300 for 100 times the amount of data, they will have an irrefutable advantage over anybody that has not been able to leverage economies of scale."
So, let's do some simple examples. I'll focus on a backup solution just for employee workstations, each employee has 100GB of personal data to backup on their laptop or PC. We'll look at a one-person company, a ten-person company, and a hundred-person company.
Case 1: The one-person company
Here the sole owner needs a backup solution. Here are all the steps she might perform:
Spend hours of time evaluating different backup products available, and make sure her operating system, file system and applications are supported
Spend hours shopping for external media, this could be an external USB disk drive, optical DVD drive, or tape drive, and confirm it is supported by the selected backup software.
Purchase the backup software, external drive, and if optical or tape, blank media cartridges.
Spend time learning the product, purchase "Backup for Dummies" or similar book, and/or taking a training class.
Install and configure the software
Operate the software, or set it up to run automatically, and take the media offsite at the end of the day, and back each morning
Case 2: The ten-person company
I guess if each of the ten employees went off and performed all of the same steps as above, there would be no economies of scale.
Fortunately, co-workers are amazingly efficient in avoiding unnecessary work.
Rather than have all ten people evaluate backup solutions, have one person do it. If everyone runs the same or similar operating system, file systems and applications, this can be done about the same as the one-person case.
Ditto on the storage media. Why should 10 people go off and evaluate their own storage media. One person can do it for all ten people in about the same time as it takes for one person.
Purchasing the software and hardware. Ok, here is where some costs may be linear, depending on your choices. Some software vendors give bulk discounts, so purchasing 10 seats of the same software could be less than 10 times the cost of one license. As for storage hardware, it might be possible to share drives and even media. Perhaps one or two storage systems can be shared by the entire team.
For a lot of backup software, most of the work is in the initial set up, then it runs automatically afterwards. That is the case for TSM. You create a "dsm.opt" file, and it can list all of the include/exclude files and other rules and policies. Once the first person sets this up, they share it with their co-workers.
Hopefully, if storage hardware was consolidated, such that you have fewer drives than people, you can probably have fewer people responsible for operations. For example, let's have the first five employees sharing one drive managed by Joe, and the second five employees sharing a second drive managed by Sally. Only two people need to spend time taking media offsite, bringing it back and so on.
Case 3: The hundred-person company
Again, it is possible that a hundred-person company consists of 10 departments of 10 people each, and they all follow the above approach independently, resulting in no economies of scale. But again, that is not likely.
Here one or a few people can invest time to evaluate backup solutions. Certainly far less than 100 times the effort for a one-person company.
Same with storage media. With 100 employees, you can now invest in a tape library with robotic automation.
Purchase of software and hardware. Again, discounts will probably apply for large deployments. Purchasing 1 tape library for all one hundred people is less than 10 times the cost and effort of 10 departments all making independent purchases.
With a hundred employees, you may have some differences in operating system, file systems and applications. Still, this might mean two to five versions of dsm.opt, and not 10 or 100 independent configurations.
Operations is where the big savings happen. TSM has "progressive incremental backup" so it only backs up changed data. Other backup schemes involve taking period full backups which tie up the network and consume a lot of back end resources. In head-to-head comparisons between IBM Tivoli Storage Manager and Symantec's NetBackup, IBM TSM was shown to use significantly less network LAN bandwidth, less disk storage capacity, and fewer tape cartridges than NetBackup.
The savings are even greater with data deduplication. Either using hardware, like IBM TS76750 ProtecTIER data deduplication solution, or software like the data deduplication capability built-in with IBM TSM v6.1, you can take advantage of the fact that 100 employees might have a lot of common data between them.
So, I have demonstrated how savings through economies of scale are achieved using IBM Tivoli Storage Manager. Adding one more person in each case is cheaper than the first person. The situation is not linear as Scott suggests. But what about larger deployments? IBM TS3500 Tape Library can hold one PB of data in only 10 square feet of data center floorspace. The IBM TS7650G gateway can manage up to 1 PB of disk, holding as much as 25 PB of backup copies. IT Analysts Tony Palmer, Brian Garrett and Lauren Whitehouse from Enterprise Strategy Group tried IBM TSM v6.1 out for themselves and wrote up a ["Lab Validation"] report. Here is an excerpt:
"Backup/recovery software that embeds data reduction technology can address all three of these factors handily. IBM TSM 6.1 now has native deduplication capabilities built into its Extended Edition (EE) as a no-cost option. After data is written to the primary disk pool, a deduplication operation can be scheduled to eliminate redundancy at the sub-file level. Data deduplication, as its name implies, identifies and eliminates redundant data.
TSM 6.1 also includes features that optimize TSM scalability and manageability to meet increasingly demanding service levels resulting from relentless data growth. The move from a proprietary back-end database to IBM DB2 improves scalability, availability, and performance without adding complexity; the DB2 database is automatically maintained and managed by TSM. IBM upgraded the monitoring and reporting capabilities to near real-time and completely redesigned the dashboard that provides visibility into the system. TSM and TSM EE include these enhanced monitoring and reporting capabilities at no cost."
The majority of Fortune 1000 customers use IBM Tivoli Storage Manager, and it is the backup software that IBM uses itself in its own huge data centers, including the cloud computing facilities. In combination with IBM Tivoli FastBack for remote office/branch office (ROBO) situations, and complemented with point-in-time and disk mirroring hardware capabilities such as IBM FlashCopy, Metro Mirror, and Global Mirror, IBM Tivoli Storage Manager can be an effective, scalable part of a complete Unified Recovery Management solution.

Wish I was there, looks like a lot of good information!
This week, SHARE conference is being held at the Colorado Convention Center in Denver, Colorado. I covered this conference for 10 years earlier in my career. Now, my colleague Curtis Neal covers these on a regular basis, and is giving the following presentations this week:
IBM Virtual Tape Products: DILIGENT ProtecTIER and TS7700 Update
Wednesday (1:30-2:30pm), Curtis will present IBM's premier virtual tape libraries. The TS7650G ProtecTIER Data Deduplication solution supports distributed systems like Windows, UNIX and Windows. The TS7700 supports the IBM System z mainframe.
SAN Volume Controller Update
Thursday (8:00-9:00am), Curtis will cover the latest features of the IBM System Storage SAN Volume Controller (SVC). SVC has features like thin provisioning, vDisk mirroring, and cascaded FlashCopy support.
IBM System Storage DS5000 Update
Friday (8:00-9:00am), Curtis will cover the DS5100 and DS5300, and probably the new DS5020 model. These are midrange disk systems that provide excellent performance for distributed systems, full disk encryption, and intermix of FC and SATA drives.
Unlike other conferences where people just go once and are never seen again, SHARE brings back the same people back year after year, so that you can maintain relationships across organizations, and can carry on forward-looking strategic discussions.
