On Tuesday, I covered much of the Feb 26 announcements, but left the IBM System Storage DS8000 for today so that it can haveits own special focus.
Many of the enhancements relate to z/OS Global Mirror, which we formerly called eXtended Remote Copy or "XRC", not to be confused with our "regular" Global Mirror that applies to all data. For those not familiar with z/OS Global Mirror, here is how it works. The production mainframe writes updates to the DS8000, and the DS8000 keeps track of these in cache until a "reader" can pull them over to the secondary location.The "reader" is called System Data Mover (SDM) which runs in its own address space under z/OS operating system. Thanks to some work my team did several years ago, z/OS Global Mirror was able to extend beyond z/OS volumes and include Linux on System z data. Linux on System z can use a "Compatible Disk Layout" (CDL) format (now the default) that meetsall the requirements to be included in the copy session.
IBM has over 300 deployments of z/OS Global Mirror, mostly banks, brokerages and insurance companies. The feature can keep tens of thousands of volumes in one big "consistency group" and asynchronously mirror them to any distance on the planet, with the secondary copy recovery point objective (RPO) only a few seconds behind the primary.
- Extended Distance FICON
Extended Distance FICON is an enhancement to the industry-standard FICON architecture (FC-SB-3) that can help avoid degradation of performance at extended distances by implementing a new protocol for "persistent" Information Unit (IU) pacing. This deals with the number of packets in flight between servers and storage separated by long distances, andcan keep a link fully utilized at 4Gpbs FICON up to 50 kilometers. This is particularly important for z/OS GlobalMirror "reader" System Data Mover (SDM). By having many "reads" in flight, this enhancementcan help reduce the need for spoofing or channel-extender equipment, or allow you to choose lower-costchannel extenders based on "frame-forwarding" technology. All of this helps reduce your total cost of ownership (TCO)for a complete end-to-end solution.
This feature will be available in March as a no-charge update to the DS8000 microcode.For more details, see the [IBM Press Release]
- z/OS Global Mirror process offload to zIIP processors
To understand this one, you need to understand the different "specialty engines" available on the System z.
On distributed systems where you run a single application on a single piece of server hardware, you mightpay "per server", "per processor" or lately "per core" for dual-core and quad-core processors. Software vendors were looking for a way to charge smaller companies less, and larger companies more. However, you might end up paying the same whether you use 1GHz Intelor 4GHz Intel processor, even though the latter can do four times more work per unit time.
The mainframe has a few processors for hundreds or thousands of business applications.In the beginning, all engines on a mainframe were general-purpose "Central Processor" or CP engines. Based on theircycle rate, IBM was able to publish the number of Million Instructions per Second (MIPS) that a machine witha given number of CP engines can do. With the introduction of side co-processors, this was changed to "Millionsof Service Units" or MSU. Software licensing can charge per MSU, and this allows applications running in aslittle as one percent of a processor to get appropriately charged.
One of the first specialty engines was the IFL, the "Integrated Facility for Linux". This was a CP designatedto only run z/VM and Linux on the mainframe. You could "buy" an IFL on your mainframe much cheaper than a CP,and none of your z/OS application software would count it in the MSU calculations because z/OS can't run on theIFL. This made it very practical to run new Linux workloads.
In 2004, IBM introduced "z Application Assist Processor" (zAAP) engines to run Java, and in 2006, the "z Integrated Information Processor" (zIIP) engines to run database and background data movement activities.By not having these counted in the MSU number for business applications, it greatly reduced the cost for mainframe software.
Tuesday's announcement is that the SDM "reader" will now run in a zIIP engine, reducing the costs for applicationsthat run on that machine. Note that the CP, IFL, zAAP and zIIP engines are all identical cores. The z10 EC hasup to 64 of these (16 quad-core) and you can designate any core as any of these engine types.
- Faster z/OS Global Mirror Incremental Resync
One way to set up a 3-site disaster recovery protection is to have your production synchronously mirrored to a second site nearby, and at the same time asynchronously mirrored to a remote location. On the System z,you can have site "A" using synchronous IBM System Storage Metro Mirror over to nearby site "B", and alsohave site "A" sending data over to size "C" using z/OS Global Mirror. This is called "Metro z/OS Global Mirror"or "MzGM" for short.
In the past, if the disk in site A failed, you would switch over to site B, and then send all the data all over again. This is because site B was not tracking what the SDM reader had or had not yet processed.With Tuesday's announcement, IBM has developed an "incremental resync" where site B figures out what theincremental delta is to connect to the z/OS Global Mirror at site "C", and this is 95% faster than sendingall the data over.
- IBM Basic HyperSwap for z/OS
What if you are sending all of your data from one location to another, and one disk system fails? Do you declare a disaster and switch over entirely? With HyperSwap, you only switch over the disk systems, but leave therest of the servers alone. In the past, this involved hiring IBM Global Technology Services to implementa Geographically Dispersed Parallel Sysplex (GDPS) with software that monitors the situation and updates thez/OS operating system when a HyperSwap had occurred. All application I/O that were writing to the primary locationare automatically re-routed to the disks at the secondary location. HyperSwap can do this for all the disk systems involved,allowing applications at the primary location to continue running uninterrupted.
HyperSwap is a very popular feature, but not everyone has implemented the advanced GDPS capabilities.To address this, IBM now offers "Basic HyperSwap", which is actually going to be shipped as IBMTotalStorage Productivity Center for Replication Basic Edition for System z. This will run in a z/OSaddress space, and use either the DB2 RDBMS you already have, or provide you Apache Derby database for thosefew out there who don't have DB2 on their mainframe already.
Update: There has been some confusion on this last point, so let me explain the keydifferences between the different levels of service:
- Basic HyperSwap: single-site high availability for the disk systems only
- GDPS/PPRC HyperSwap Manager: single- or multi-site high availability for the disk systems, plus some entry-level disaster recovery capability
- GDPS/PPRC: highly automated end-to-end disaster recovery solution for servers, storage and networks
I apologize to all my colleagues who thought I implied that Basic HyperSwap was a full replacement for the morefull-function GDPS service offerings.
- Extended Address Volumes (EAV)
Up until now, the largest volume you could have was only 54 GB in size, and many customers still are using 3 GB and 9 GB volume sizes. Now, IBM will introduce 223 GB volumes. You can have any kind of data set on these volumes,but only VSAM data sets can reside on cylinders beyond the first 65,280. That is because many applications still thinkthat 65,280 is the largest cylinder number you can have.
This is important because a mainframe, or a set of mainframes clustered together, can only have about 60,000disk volumes total. The 60,000 is actually the Unit Control Block (UCB) limit, and besides disk volumes, youcan have "virtual" PAVs that serve as an alias to existing volumes to provide concurrent access.
Aside from the first item, the Extended Distance FICON, the other enhancements are "preview announcements" which means that IBM has not yet worked out the final details of price, packaging or delivery date. In many cases, the work is done, has been tested in our labs, or running beta in select client locations, but for completeness I am required to make the following disclaimer:
All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced for general availability.

|Today was a special day! IBM launched the world's first "Global Archive Solutions Center" in Guadalajara, Mexico.We had a formal "ribbon cutting", shown here were the following dignitaries (from left to right):|
- Eugenio Godard, IBM Guadalajara site level executive
- Andy Monshaw, IBM General Manager of IBM System Storage
- Cindy Grossman, IBM VP of Tape and Archive solutions
- Luis Guillermo Martinez Mora, Secretary of economic development for the state of Jalisco, Mexico
- José Décurnex, IBM General Manager for the country of Mexico
In the morning, we had a series of speeches from Cindy Grossman, Andy Monshaw, Eugenio Godard, and Federico Lepe (technology advisor for the governor for the state of Jalisco, Mexico).
|While the hordes of press journalists, analysts and clients were taking the lab tour, we took a snap of thefront entrance. The day was packed with activity. |
- After the lab tour, IBMers Clod Barrera and Craig Butler presented to the analysts.
- Cindy Grossman explained why IBM created a solutions center specific to archive solutions, and why wechose Guadalajara for its location.
- I presented the pains and challenges companies are facing, and why they should partner with IBM forarchive solutions to address those requirements
|Harley Puckett and I split the group. Harley is my colleague at the IBM Tucson ExecutiveBriefing Center who was the focal point for the various aspects of launching for the past eight months.He presented and moderated the presentations and demos to a collection of prospective clients. |
That's me on the left, with Harley on the right.
I moderated a series of speakers to press and analysts. These included:
- Mark LaBelle, Spectrum Health server and storage manager, and Steve Lawrence, Spectrum Health image solutions architect, presented their success story using IBM Grid Medical Archive Solution (GMAS). [Spectrum Health] manages seven hospitals and 130 service locations in Michigan, USA.

The proof-of-concept that IBM Haifa research center developed back in 1998 became what we now call the iSCSI protocol.The book iSCSI: The Universal Storage Connection
introduces the history as follows:
In the fall of 1999 IBM and Cisco met to discuss the possibility of combining their SCSI-over-TCP/IP efforts. After Cisco saw IBM's demonstration of SCSI over TCP/IP, the two companies agreed to develop a proposal that would be taken to the IETF for standardization.
There are three ways to introduce iSCSI into your data center:
- Through a gateway, like the IBM System Storage N series gateway, that allows iSCSI-based servers connect to FC-based storage devices
- Through a SAN switch or director, a FC-based server can access iSCSI-based storage, an iSCSI-based server accessing FC-based storage, or even iSCSI-based servers attaching to iSCSI-based storage.
- Directly through the storage controller.
IBM has been delivering the first method with its successful IBM System Storage N series gateway products, buttoday we have announced additional support for the second and third methods.Here's a quick recap.
- New SAN director blades
Supporting the second method, IBM TotalStorage SAN256B Director is enhanced to deliver iSCSI functionality with a new M48 iSCSI Blade, which includes 16 ports (8 Fibre Channel ports; and 8 Ethernet ports for iSCSI connectivity). We also announced a new Fibre Channel M48 Blade which provides 10 Gbps Fibre Channel Inter Switch Link (ISL) connectivity between SAN256B Directors.
- Entry Level Disk Systems
Supporting the third method, IBM introduces new iSCSI-capabable disk systems, including the IBM System Storage DS3300 model using SAS drives, N3300 A10/A20 models and N3600 A10/A20 models supporting use of FC and SATA drives.The DS3000 Express models include frequently requested options, including appropriate host bus adapters (HBA) and cables. Likewise, we have announced hardware features for our IBM N series , such as TCP offload engine (TOE) network interface cards (NIC), HBA and cables.
With support for Boot-over-iSCSI, diskless rack-optimized and blade servers can boot Windows or Linux over Ethernet,eliminating the management hassles with internal disk.
All of this is part of IBM's overall push into the Small and Medium size Business marketplace, making it easier to shop for and buy from IBM and its many IBM Business Partners, easier to deploy and install storage, and easier tomanage the storage once you have it.

Well it's Tuesday, which means its time to look at recent announcements.While I was on vacation last week, IBM made a lot of storage announcements October 23.Josh Krischer gives his summary on WikiBon [October 2007 Review
].Austin Modine of the The Register
went so far as to say that [IBM goes crazy with storage system updates
- IBM System Storage DS8000 series
This is "Release 3" software/microcode upgrades on our existing "Turbo" hardware.
- IBM FlashCopy SE -- Here "SE" stands for Space Efficient. Rather than allocating a full 100% of the space for the FlashCopy destination, you can set aside just a fraction, and this will hold all the changed blocks, similar to whatIBM already offers on the DS4000 series.
- Dynamic Volume Expansion -- In the past, if you needed more space for a LUN, you had to carve out a newer one elsewhere, and then copy the data over from the old to the new, leaving the old LUN around to be re-used or leftstranded. With this enhancement, you can just upgrade the LUN in place, making it bigger as needed, similar to whatIBM already offers on the DS4000 series and SAN Volume Controller. This applies to CKD volumes for the System zmainframe users out there as well.
- Storage Pool Striping -- striping volumes across RAID ranks to eliminate or reduce hot-spots, and provide betterload balancing. Many used SAN Volume Controller in front of the DS8000 to do this, but now you can do it natively inthe DS8000 itself.
- z/OS Global Mirror Multiple Reader -- for System z customers, "z/OS Global Mirror" is the new name for XRC. Thisenhancement improves the throughput of sending updates to the remote disaster recovery location.
- DS Storage Manager enhancements, the element manager software has been enhanced, and is pre-installed on the new IBM System Storage Productivity Center, which I will talk about below.
- Intermix of DS8000 machine types -- this is especially useful to allow new frames to have co-terminating warrantieswith the base units. In other words, as you expand your system, you can ensure that the entire chunk of iron runs outof warranty all at the same time, to simplify your decision making process to upgrade or contract for extended service.
See the [DS8000 Announcement Letter] for more details.
- IBM System Storage SAN Volume Controller 4.2.1
BarryW summarizes the updates in the[Announced SVC 4.2.1] release.If you have problems with the link he provides in his post, here is the [SVC 4.2.1 Announcement Letter].
- IBM System Storage Productivity Center
One of the biggest complaints about IBM TotalStorage Productivity Center is that it is software that needs to beinstalled on its own server, and that this installation process can take a day or two. Why wait? Now you can havea hardware console that has the DS8000 Storage Manager software, SVC Admin Console software, and IBM TotalStorageProductivity Center "Basic Edition" pre-installed. Here are the key features.
- Pre-installed and tested console
- DS8000 R3 GUI integration
- Cohabitation of SVC 4.2.1 GUI and CIMOM
- Automated device discovery
- Asset and capacity reporting, including tape library support
- Device configuration
- Advanced topology viewer
See the[System Storage Productivity Center - Announcement letter] for more details."Basic Edition" can be upgraded to "Standard Edition" to get full functionality.
- IBM System Storage N series
Our "Release 9" applies across the board, from N3000 to N5000 to N7000 series models, includingnew host bus adapters, and the new Data OnTAP 7.2.4 release level.
The Virtual File Manager (VFM) was announced as one of our latest [Storage Virtualization Solutions]. VFMprovides a global namespace that aggregates the file systems from Linux, UNIX, and Windows file servers, as well asN series storage, into a consolidated environment.
See the [N series Announcement Letter] for more details.
- IBM TS7520 Virtualization Engine
IBM's virtual tape library (VTL) for the distributed systems platform, has been enhanced to provide:
- Up to 12TB of disk cache, using 750GB SATA disk.
- F05 Tape Frames installed as TS7520 base units through a 32 port fibre channel switch
- Support for LTO generation 4 tape drives, both as virtual tape drives and as physical tape drives within IBM automated tape libraries attached to the TS7520. This allows you to use Encryption capabilities of LTO4.
See the [TS7520 Announcement Letter] for more details.
- IBM System Storage DS6000 series
The latest 300GB 15K RPM drives are now supported.
- IBM System Storage DS4000 series
This was a software/microcode upgrade release for the DS4000 series.
- RAID-6 support on the DS4700 Express models and the DS4200 Model 7V
- Support for greater than 2 TB volumes on selected supported operating systems
- 8K cache block size
- DS4000 Storage Manager v10.10 increases the number of FlashCopy tasks, remote mirror pairs, and storage partitions.
See the [DS4000 Announcement Letter] for more details.
- IBM System Storage DS3000 series
DS3000 series now supports SATA disk, and can be attached to AIX and Linux on System p servers. This appliesto the DS3200, DS3300 and DS3400 models.See the [DS3000 Announcement Letter] for more details.
- IBM System Storage TS2240
These are LTO4 Half-High drives, which can support encryption.See the [TS2240 Announcement Letter] for details.
Perhaps Austin is right, we might have gone crazy announcing all of this at once.

When times are tough, people revert back to their "default programming", and companies search for their"core strengths".The Redwoods Group calls this the[Native Language Theory
]. Here'san excerpt:
A young carpenter immigrates to the United States from Italy, unable to speak a word of English. Upon arrival, he moves into a small apartment by himself and begins looking for a job in construction. With some luck and a lot of hard work, he quickly lands a job at a local construction site. Over the coming weeks he learns how to say “hello” and “goodbye” to his English-only coworkers. As time goes on, he is able to learn more complex phrases and commands and is now able to begin taking on jobs that better match his level of expertise.
Several years after the carpenter moved to the US, he now speaks fluent English and has started a family with an American woman and now speaks only English on the job site and at home. One afternoon, while hammering at the framing of a new home, the carpenter strikes his thumb. In what language does he curse?Italian, of course.
We believe that this story illustrates the nature of reacting to difficult, stressful, and, yes, painful situations by reverting to what you know best. This is the reason that coaches ask their players to make certain actions “instinctual” – simply, when times get tough, we do what we fall back on our native language.
Last September, in my post[Supermarketsand Specialty Shops] I mentioned how Forrester Research identified two kinds of IT vendors selling storage. On one side were the"information infrastructure" companies (IBM, HP, Sun, and Dell) that focus on providing one-stop shopping for clients that want all parts of an IT solution, including servers, storage, software and services. These I compared to "supermarkets".
On the other side were the storage component vendors (EMC, HDS, NetApp, and many others) that focus on specificstorage components. These I compared to "specialty shops", like butchers, bakers and candlestick makers.These often appeal to customers with big enough IT staffs with the skills to do their own system integration.The key difference seems to be that the supermarkets are client-focused, and the specialty shops are technology-focused, and different people prefer to do business with one side or another.This came in handy last November to explain Dell's acquisition of EqualLogic and discuss[IBMEntry-Level iSCSI offerings].
Some recent news seems to fit this model, in relation to the Native Language Theory.
Several argued that EMC was in the process of shifting sides, from disk specialty shop over to an everything-but-servers supermarket. Certainly many of its acquisitions in software, services, and VMwarewould support the notion that perhaps they are going through an identity crisis.The immediate beneficiary was HDS, the #2 disk specialty shop, that passedup EMC with innovative features in its USP-V disk system.
However, times are tough, especially in the U.S. economy that many storage vendors are focused on. EMCappears to have found its native language, going back to its roots of solid state storage systems thatthey started with back in 1979. This week EMC announced [Symmetrix DMX-4 support of Flash drives].Several bloggers review the technology involved:
Overall smart move for EMC to go back to its technology-focused disk specialty shop mode and go head-to-head against the HDS threat. With Web 2.0 workloads moving off these monolithic solutions and onto [clustered storage more appropriate for "cloud computing"], large enterprise-class disk systems like theIBM System Storage DS8000 and EMC DMX-4 can shift focus on what they do best: online transaction processing (OLTP) and large databases. However,I noticed the EMC press release mentions EMC as an "information infrastructure" company, so perhaps they stillhaven't resolved their identity crisis.
(For the record, IBM shipped [Flash drive-based storage last year], and announced [larger drive models] this week. As we have learned from last year, terms like "First" or "Leader" in corporate press releases should not always be taken literally.)
- Sun Microsystems
After Sun acquired StorageTek specialty shop, they too had a bit of an identity crisis.Fortunately, they realized their core strengths were on the "supermarket" side,moved storage in with servers in their latest restructuring, changed their NYSE symbol from SUNW to JAVA, and reset their focus on providing end-to-end solutions like IBM. For example, fellow blogger Taylor Allis from Sun mentions their latest in "clustered storage" in his post[IBM Buys XIV - Good Move].
Last August, in my post [Fundamental Changes for Green Data Centers], I mentioned that IBM consolidated 3900 rack-optimized servers onto 33 mainframes,and that this was part of our announcement that[since 1997, IBM has consolidated its strategic worldwide data centers from 155 to seven].I noticed in Nick Carr's Rough Type blog post[The Network is the Data Center] thatHP and Sun have followed suit:
In an ironic twist, some of today's leading manufacturers of server computers are also among the companies moving most aggressively to reduce their need for servers and other hardware components. Hewlett-Packard, for instance, is in the midst of a project to slash the number of data centers it operates from 85 to 6 and to cut the number of servers it uses by 30 percent. Now, Sun Microsystems is upping the stakes. Brian Cinque, the data center architect in Sun's IT department, says the company's goal is to close down all its internal data centers by 2015. "Did I just say 0 data centers?" he writes on his blog."Yes! Our goal is to reduce our entire data center presence by 2015."
While Nick feels this is ironic for Sun, known for UNIX servers based on their SPARC chip technology, I don't. Sun has shifted from being technology-focused to being client-focused.This is where the marketplace is going, and the supermarket vendors, being client-focused, are best positioned to adapt to this new world. In a sense, Sun found its roots. Nick summarizes this as:"The network, to spin the old Sun slogan, becomes the data center."
So, each move seems to strengthen their respective identities back to their origins, or at least help them communicate that to the market.

Continuing my two-part series on this week's announcements, I presentIBM's latest for tape and storage software.
- IBM TS7650 and TS7650G ProtecTIER deduplication
In addition to the [TS7650G gateway model] new [Enterprise Edition V2 software], IBM announced four new [TS7650 appliance models] for a complete, integrated solution. The fourconfigurations include the controller and disk:
- 7TB, single controller
- 18TB, single controller
- 36TB, single controller
- 36TB, dual controller in clustered configuration
These disk capacities can have up to 25x times their effective capacity with IBM's HyperFactorin-line deduplication capability. So the smallest 7TB model could be as effective as 175TB of traditionaldisk storage.
- IBM Tivoli Storage Manager (TSM) v6
After years and years in development, IBM announces[TSM v6]. Here's a quick summary of the key features:
- DB2 instead of an internal database
For years, people have complained that IBM used its own internal relational database. This was becausewhen TSM was first launched back in 1993, the DB2 did not have all the features on all of the various server platforms that TSM needed. Today, DB2is the leading relational database on all the key platforms that TSM server runs on, and therefore good enough for use within Tivoli Storage Manager. If you don't already have DB2, it is included for use with TSM v6.1 at no additional charge. Do you have to become a DB2 expert to use TSM? No! The TSM administration commands have been updated to hide all the complexity of DB2 away, behind the scenes. You now just use TSM commands to administer the database,as you did before. IBM will provide conversion utilities to help existing TSM customers migrate to thisnew database environment.
- Better Operational Reporting
Another big complaint was that TSM had fixed reporting, and administrators that wanted customized reportsoften had to resort to purchasing third party products. With the change over to DB2, TSM now enables youto create your own reports using Eclipse's Business Intelligence and Reporting Tools[BIRT]! If you haven't used BIRT, you can downloada free open source copy and start playing around with its capabilities. This is combined with a revamped GUI that provides a customizable dashboard using IBM's Integrated Solutions Console (ISC)infrastructure.
- Software-based Deduplication
Lastly, IBM has incorporated deduplication capability within the TSM v6.1 software for its own diskstorage pools. This is done in a post-process manner so as to dedupe all of your legacy backup dataas well, not just the new stuff, without impacting the current TSM server performance.
At this point, you might be thinking "Wait, what about IBM TS7650 ProtecTIER deduplication?" which is really two questions.
- Can I use TSM v6.1 with IBM TS7650 ProtecTIER?
Yes, however since TSM progressive incremental method is vastly more efficientthan other backup products like Veritas NetBackup or EMC Legato NetWorker, the TS7650 may only get 10x reductionof TSM backups, versus up to 25x with full-backups-every-night backup schemes. TSM only dedupes itsdisk storage pools, so it won't dedupe data directed at tape systems like the TS7650 or othertape libraries. This avoids the "double dedupe" concern.
- When should I use TSM's software version versus TS7650's hardware deduplication?
This is a positioning question. For now, the cut-over point is about 10TB per night backup processing. If youbackup more than 10TB per night, TS7650 hardware may be the better approach. If you are a smaller customer nowhere near that volume of data, then using TSM v6.1 software deduplication may be a morecost-effective solution. If you start small, and grow beyond 10TB per night, it is easy to bring ina TS7650 into an existing TSM environment and migrate the data over.
- Sub-capacity Licensing
If you run TSM server on a logical partition (LPAR) or virtual guest OS under VMware ESX, Xen or Microsoft'sHyper-V environment, why should you have to license it for the whole box? With TSM v6.1, you nowcan pay for only the amount of processors you use, down to a single core even.If you currently run TSM v5 on z/OS, you can migrate over to TSM v6.1 server for Linux on System z totake advantage of cost savings using IFL engines.
- IBM Tivoli Key Lifecycle Manager (TKLM) v1.0
Don't let the "v1.0" scare you, this is the successor to IBM's Encryption Key Manager (EKM) that hasthousands of clients using today with IBM encrypting tape drives. The new TKLM adds support for full disk encryption (FDE) drives--like those for the DS8000 I mentioned in [yesterday's post]--as well as new features to support key rotation for compliance and business controls.
- IBM Tivoli Storage Productivity Center
Last, but not least, we have IBM Tivoli Storage Productivity Center [TSPC]. No, that is not a typo. IBM is renaming IBM TotalStorage Productivity Center to Tivoli Storage Productivity Center toavoid trademark conflicts with the [Professional Golfer's Association].
This is not just renaming existing product. Here some key improvements:
- TSPC brings back together Productivity Center Standard Edition (Disk, Tape, SAN and Data) with Productivity Center for Replication, which were separate at birth a few years ago.
- TSPC adds support for IBM's Storage Enterprise Resource Planner[SERP] from theNovusCG acquisition.
- End-to-end view for EMC storage devices connected to supported servers via EMC Powerpath multipathing driver. As customers switch away from EMC Control Center over to IBM's Productivity Center, IBM can continue to provide support for existing EMC gear.
Of course, IBM will still offer IBM System Storage Productivity Center[SSPC] which is a piece of hardware pre-installed with Productivity Center software.
Hopefully, you can now see why I had to split up all these announcements into separate posts acrossmultiple days!

IBM had some big announcements today. The theme for today's announcement was "Protected Information", as there are many reasons to protect your most strategic asset, your information. Let's do a quick run-down of a few of them.
- IBM LTO generation 4
LTO 4 provides encryption at the drive level, and supports WORM cartridges similar to LTO 3. It continues the LTO consortium's strategy for higher capacity and faster performance. If you have LTO 1 or LTO 2, now is a good time to consider upgrading your tape technology. The combination of encryption and WORM protects your information against unauthorized access, and unethical tampering of the data. The support is from our largest automated tapelibrary (TS3500),to our smallest drives.
- TS7520 Virtualization Engine
The TS7520replaces the TS7510, providing enhanced Virtual Tape Library (VTL) capability. When you hear "storage virtualization" you often think disk, but IBM invented "tape storage virtualization" and this product continues that leadership.
- Support for Half-high LTO 3 drives
The TS3100 and TS3200 now support half-high LTO 3 drives, which means you can have twice the number of drives in each unit. LTO 4 drives can read and write to LTO 3 media, so this provides additional investment protection.
- IBM System Storage DR550 File System Gateway
This new offering provides much-needed CIFS and NFS access to the DR550, the worlds most flexible compliance-and-retention storage available. Already there is a large body of ISVs that support the DR550 today, and with this new gateway, the list is even longer. The DR550 provides encryption for both disk and tape data, as well as policy-based non-erasable, non-rewriteable enforcement, designed for compliance with government regulations like Sarbanes-Oxley Act, HIPAA, and many others.
- IBM System Storage SAN32B-3 switch
This is the first major deliverable from Brocade since their acquisition of McDATA. A powerful switch packs 4 Gbps support in a small 1U form factor. Start with 16 ports, then add in increments of 8 ports to a maximum of 32 ports.
I've provided all the links, so that you can delve deeply into all the data sheets.

Normally, IBM only makes announcements on Tuesdays, but today, Friday, IBM announces that it acquired Diligent Technologies. What? I got a lot ofquestions about this, so I thought I would start with this...
When I posted in January that[IBM Acquires XIV],fellow EMC blogger Mark Twomey of StorageZilla fame, sent me a comment:
"Ah now Tony I wasn't poking fun. Indeed I find it fascinating that Moshe who's been sitting out on the fringes for years having been banished for being an obstructionist to EMC entering the mid-market is now back.
Which reminds me what happens with Diligent? There his as well aren't they or has he packed his stake in that in?"
As you might have guessed, I am privy to a lot of stuff going on behind the scenes at IBM that I can't talk about in this blog, and all these rumors in the blogosphere about IBM acquisition of Diligent was a topic I couldn't officially recognize, defend or deny, until official IBM announcements were made.
In his latest post, Mark wonders about[the last Tape and Mainframe sales person on earth]. He recounts my interaction with fellow HDS blogger Hu Yoshia about the energy benefits ofVirtual Tape Libraries. Knowing that we were going to announcement IBM's acquisition of Diligent soon, I thoughtthis would be a worthy exchange, driving up the sales of Diligent boxes (whether you buy them from IBM or HDS).Diligent already had reselling arrangements with HDS, and IBM plans to continue thosearrangements going forward with HDS. As I have explained before in my post [Supermarketsand Specialty Shops], IBM and HDS cater to different customers, so if a customer who wants the best technologyfrom a specialty shop, they can buy IBM Diligent products from HDS, but if they want one-stop shopping, they can buyIBM Diligent directly from IBM or its other IBM Business Partners.
(Perhaps a more tricky situation is that Diligent also had an arrangement with Sun Microsystems, which competesdirectly against IBM as another IT supermarket vendor, but I have not heard how IBM has decided to handle thisgoing forward.)
For more on this intricate mess of interconnected companies, alliances and partnerships, read Dave Raffo's article[Data dedupe dance cardfilling up] over at Storage Soup.
So, let's tackle the first question:
- Q1. What will happen to IBM's real tape library business?
Come on! IBM is Number one in tape, we've had virtual tape libraries since 1997 (the first in the industry)and continue to do well in both virtual and real tape libraries. Both provide value to the customer, and bothhave their place as part of the overall "information infrastructure". This acquisition provides yet another choicefor clients on our "supermarket" shelf.
(For those following the ["which is greener"] discussion, the robot of the IBM TS3500 real tape library consumes185W per frame (when moving) and each tape drive consumes 50W (when actively working on a tape). Compared to 13W per SATA disk drive, each 6-drive frame of a TS3500 consumes as much electricity as 37 SATA disk drives. If you are not running backups 24x7, the total KWh per day for your tape library is actually quite less, but as several people have pointed out, there are customers that do run backups 80-90 percent of the time. LTO-4 tapes can hold 800GB uncompressed, and SATA disk are now available in 1TB (1000 GB) size, so you can have fun with your own comparisons.)
Meanwhile, Scott Waterhouse, one of the few people at EMC who understand tape workloadslike backup and archive, takes me to task in his Backup Blog
with his post[I want a Red Ferrari
].For those who are surprised that anyone at EMC might understand backup workloads, EMC did acquire a company calledLegato, and perhaps Scott came from that acquisition. I've never met Scott in person, but based solely only fromhis writings, he seems to know his stuff and makes strong arguments for using IBM Tivoli Storage Manager (TSM) with deduplication and virtual tape libraries.
While TSM does a good job of "deduplicating" at the client first, backing up only changed data, Scott feels database and email repositories must be backed up entirely each time, which is what happens in many other backup software products. Some clients might have 80 percent database/email and only 20 percent files, while others might have less than 20 percent database/email and 80 percent files, so this might influence whether deduplication will have small or big benefit.If TSM has to backup the entire database, even though little has changed since the last backup, that is where deduplication on a virtual tape library can come in handy. For IBM DB2 and Oracle databases, IBM TSM application-aware Tivoli Data Protection module interface backs up only changed data, not the entire file. Thanks to IBM's FilesX acquisition-- (also coincidently from Israel) --IBM can extend this support now to SQL Server databases as well.However, to be fair, Scott is partly correct, TSM does backup some database and email repositories in their entirety, which is why it is a good idea to have BOTH an IBM virtual tape library with deduplication and Tivoli Storage Manager to handle all cases. This brings us to the next question:
- Q2. What will happen to IBM's patented "progressive backup" technology?
IBM will continue to use TSM's progressive backup technology. TSM already works great with Diligent virtual tapelibraries. One example is LAN-free backup. In this configuration, the TSM client writes its backups directly toa virtual or real tape library, over the SAN, and then sends the list of files backed up to the TSM server over theLAN to record in its database. This can greatly reduce IP traffic on your LAN during peak backup periods. For more about this, see the IBM Redbook titled["Get More Out of Your SAN with IBM Tivoli Storage Manager"].
Jon Toigo from DrunkenData asks[Did IBM Do Due Diligence Before Making Diligent Acquisition a Done Deal?] which is probably always a valid question. Unlike XIV, I wasn't part of the Diligent acquisition team, so I can't provide first hand account of the process. I am told that the IBM team did all the right things to make sure everything is going to turn out right.Sadly, many companies that make acquisitions in the IT industry fail to make them work. Fortunately, IBM is one of the few companies that has a great success record, with over 60 acquisitions in the past six years.In the Xconomy forum, Wade Rousch writes[IBM and the Art of Acquisitions]and gives some insight why IBM is different. Jon did not understand why Cindy Grossman, IBM VP of tape and archive solutions, ran the analyst conference call for this announcement, which brings me to the next question:
- Q3. What is Diligent virtual tape library going to be categorized as, a disk system or a tape system?
IBM organizes its storage systems based on the host application workloads.Products to address disk workloads (SVC, DS8000 series, DS6000 series, DS4000 series, DS3000 series, N series, XIV Nextra) are in our disk systems group. Storage that appears to host applications like a tape system to address workloads like backup and archive (tape drives, libraries and tape virtualization) are in our tape and archive group. IBM Diligent has two products, one for big workloads and one for medium workloads. Both look liketape systems, so our tape and archive team, who understand tape workloads like backup and archive the best, are obviously the best choice to support IBM Diligent in the mix.
Some might remember that IBM already has deduplication in its IBM N series products, called Advanced Single InstanceStorage, or A-SIS. Here is an[IBM System Storage N Series A-SIS Deduplication Deployment and Implementation Guide. This brings up the fourth question:
- Q4. What will happen to N series A-SIS feature?
IBM will offer both N series and Diligent deduplication capabilities. For disk workloads, IBM N series offers a post-process deduplication feature at no additional charge. For tape workloads, IBM will now offer an in-line deduplication feature with Diligent Technologies. Different workloads, different offerings.
As with any acquisition, there will be some changes. The 100 folks from Diligent will get to learn the IBM wayof doing things. This brings me to our fifth and final question:
- Q5. What is the correct spelling: deduplication or de-duplication?
It appears that Diligent has a corporate-wide standard to hyphenate this term (de-duplication), but the "word police" at IBM that control and standardize all "proper spellings, trademarks, and capitalization" have sent me corporate instructions a few days ago that IBM does not to hyphenate this term (deduplication). So, going forward, it will be "deduplication", or "dedupe" for short.I suspect one of the first tasks that our new IBMers from Diligent will be doing is removing all those hyphens fromthe [Diligent Technologies website]!
That's all for now, I'm off to Chicago, Illinois tomorrow!

It's Tuesday, which means IBM announcements, and today IBM made some major announcementsthat support a [Dynamic Infrastructure
]! I hinted at this yesterday, choosing the week's theme to be all about Cloud Computing and Alternative Sourcing. I will briefly highlight today's announcements related to storage here, and try to go into more detail over the next few weeks.
- Ethernet switches and routers
In support of Cloud Computing and Cloud Storage, IBM is now back in theEthernet networking business. This is part of storage as protocols likeiSCSI, CIFS and NFS are gaining prominence. Extending IBM's existing OEMrelationship with Brocade, there are four series:
- [c-series] - "c" for Compact, these are 1U high fixed port switches
- [g-series] - "g" for Pay-as-you-Grow using IronStack stacking technology to allow up to 8 switches to be
glommed, glued, er.. "gathered" together as a single virtual chassis.
- [m-series] - "m" for Multiprotocol Label Switching [MPLS] which supports routing between LAN and WAN networks over OC12 and OC48 lines.
- [s-series] - "s" for slots, the B08S has eight slots, and the B16S has sixteen slots, supporting up to 384 ports. These models support Power-over-Ethernet [PoE] that simplifies attaching Voice-over-IP (VoIP) telephones and IP-based surveillance cameras.
IBM announced it will strengthen its partnership with Juniper Networks, and continues to consider Cisco a strategic partner as well. To help customer position themselves for Cloud Computing and Cloud Storage,IBM also launches some new services:
- IBM System Storage DS5000 disk system
The IBM [DS5000] now supports self-encrypting disk drives, known also as "full-disk encryption" or FDE, for added security, and 8Gbps Fibre Channel (FC) ports for added performance. The DS5300 model in particular now supports up to 448 disk drives for added scalability.
- Comprehensive Data Protection Solution
IBM's [Data Protection Solution] shows off IBM's awesome synergy between servers, storage and software. Combining System x servers, Tivoli Storage Manager FastBack software, and DS5000, DS4000 or DS3000 series disk systems. The solution is designed to both Windows-based servers and their applications, offering bare metal restores, and application–level protection for Oracle, SQL, Exchange and SAP.
- Tivoli Storage Productivity Center
Last February, IBM previewed the renaming of TotalStorage Productivity Center to its new name,Tivoli Storage Productivity Center. Today, IBM announces [Tivoli Storage Productivity Center v4.1]. Some key changes include:
- Productivity Center for Fabric has been merged into Productivity Center for Disk
- Productivity Center for Replication is now integrated, but remains separately licensed
- Productivity Center can now feed input to IBM's Novus Storage Enterprise Resource Planner [SERP]
- TS7650 ProtecTIER Data Deduplication IP-based replication
IBM previews IP-based replication which allows the TS7650 appliance or TS7650G gateway to sendvirtual tape data over to a remote location. This is instead of having the underlying disk systemsperform the replication on its behalf. Having the TS7650 do the replication is preferred, as itcan maintain virtual cartridge integrity, when a virtual tape is unmounted the replication can beginat that point.
This is just a small subset of all the announcements. For more information, see this 28-pagepresentation [Manage the Explosion of Information with IBM Information Infrastructure].

The TS3100 Tape Library
An astute reader brought this to my attention. The newest addition to our "IBM Express Portfolio"set of SMB-oriented offerings is the new TS3100 tape library. This has one LTO Gen 3 drive and up to 22 cartridges, which can be a mix of WORM and rewriteable cartridges,beautifully packaged in a small 2U high (3.5 inch) rack-mountable chassis. Each cartridge can hold up to 800GB uncompressed, or 1.6TB with typical 2-to-1 compression.
This tape library would be a great complement to TSM Express for backup, and to theDR550 Express for archive and compliance storage.
And now, for a limited time, there is a $1500 rebate, check website for details.

Today, January 16, IBM launches its latest disk system, the DS3000 series.
There are actually three products in the DS3000 series:
The DS3200 is a 2U high, 12 drive system that attaches to servers via 3Gbps Serial Attach (SAS) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are theDS3200 specifications.
The DS3400 is a 2U high, 12 drive system that attaches to servers via 4Gbps Fibre Channel (FC) interface.You can expand this to 48 drives by added EXP3000 expansion units. Here are the DS3400 specifications.
The EXP3000 is a 2U high, 12 drive expansion drawer. It was announced back in August 2006, but is part of theoverall DS3000 series. It can be used directly with servers, but is also designed to be attached to the back of the DS3200 or DS3400 to increase capacity.Here are the EXP3000 specifications.
With this announcement, IBM provides entry-level storage at the "less-than-$5000" price point, withsupport for intermix of 10K and 15K RPM drives, and scalable up to 14.4 TB capacity.This would be ideal storage for HP, Dell, IBM System x and BladeCenter servers.

It's Tuesday, and you know what that means-- IBM makes its announcements.
Today, IBM announced a variety of storage offerings, but I am going to just focus this poston just the new DR550 models. The DR550 is the leading disk-and-tape solution forstoring non-erasable, non-rewriteable (NENR) data. This type of data, often called fixed-contentor compliance data, was previously writtento Write-Once-Read-Only (WORM) optical media. However, Optical technology has not advanced as fastas magnetic recording, so disk and tape have taken over this role. While there are still a fewlaws on the books that mandate "optical media" as the storage solution, new laws like SEC 17a-4and Sarbanes-Oxley (SOX) allow for NENR solutions based on magnetic disk or tape instead.
As we had done for the IBM SAN Volume Controller (SVC), the DR550 was based on "off the shelf"components. The File System Gateway (FSG) was based on System x server, the DR550 hardwarebased on System p server and DS4000 disk arrays, with "hardened" versions of the AIX,DS4000 Storage Manager and IBM Tivoli Storage Manager (TSM) that we renamed the IBM SystemStorage Archive Manager (SSAM).
The DR550 is Ethernet-based, so it can be used with all IBM server platforms, from System xand BladeCenter, to System i, and System p, and even System z mainframe customers, as wellas non-IBM platforms from Sun, HP and others. There are two ways to get data stored ontothe DR550:
- Sending archive objects via the SSAM archive API. This is an API based on the XBSA open standardthat many applications have coded to.
- Writing files via standard CIFS and NFS protocols through the File System Gateway (FSG), an optional priced feature that you can have incorporated into the DR550.
Generally, business applications like SAP or Microsoft Exchange don't do this directly, but ratheryou have an "archive management application" that acts as the go-between broker. IBM offers IBM Content Manager, IBM CommonStore for eMail (Exchange and Lotus Domino), and IBM CommonStore for SAP.IBM also recently acquired FileNet and Princeton Softech that provide additional support. Third partyproducts like Zantaz and Symantec KVS Enterprise Vault have also passed System Storage Provencertification for the DR550. These go-between applications understand the underlying storagestructure of their respective applications, and can apply policies to extract database rows, individualemails, or other attachments, as appropriate, and either move or copy them into the DR550.
The DR550 has built in support to move data from disk to tape, through policy-based automation behind the scenes. This is the key differentiator fromdisk-only solutions. Rather than filling up an EMC Centera, and watching it sit there idle burning energyfor five to seven years, or however long you are required to keep the data, you can instead use the disk for the most recent months worth of data on a DR550. The DR550 attaches to tapedrives or libraries, not just IBM TS1120 or LTO based models, but hundreds of systems from other vendorsas well. You can combine this with either rewriteable or WORM tape cartridge media, depending on yourcircumstances. This can be directly cabled, or through a SAN fabric environment. Storing the bulk ofthis rarely-referenced data on tape makes the DR550 substantially more affordable and more green thandisk-only alternatives.
Let's take a look at the specific models:
- IBM System Storage DR550 DR1
The DR1 machine-type-model replaces the "DR550 Express" for small and medium size business workloads. This is a singleSystem p server with anywhere from 1 to 36 TB of raw disk capacity in a nice lockable 25U cabinet (see picture at left). On the original DR550 Express, the 25U cabinet was optional, but so many people opted for it, that wemade it standard feature. You can add the File System Gateway, which is a System x running Linuxwith NFS and CIFS protocols converted to SSAM API calls.
- IBM System Storage DR550 DR2
The DR2 machine-type-model replaces the larger "DR550" for enterprise workloads. This can be either a single or dual node System p configuration, anywhere from 6 to 168 TB in raw disk capacity, in a lockable 36U cabinet. This also allows for an optional File System Gateway, and in the case of thedual node configuration, you can have two System p servers, and two System x servers with two Ethernetand two SAN switches for complete redundancy.
Common Information Model (CIM) and SMI-S interfaces have been added so that IBM Director can providea "single pane of glass" to manage all of the components of the DR550.
The system is based on high-capacity 750GB SATA drives, installed in half-drawer (eight drives, 6 TB)and full-drawer (16 drives, 12 TB) increments. Your choices will be 7+P RAID5 or 6+P+Q RAID6.Here is an Intel article that explains [RAID6 P+Q].In the future, as new disk technologies are introduced, the DR550 supports moving the disk datafrom old to new seamlessly, without disrupting the data retention policies enforcement.
For more information, here is a [6-page brochure] thathas specifications for both the DR1 and DR2 models.

Well, it's Tuesday again, and we had several announcements this month, so here is a quick recap.We had some things announce May 13, and then some more announcements today, but since I was busywith conferences, will combine them into one post for the entire month of May 2008.
This time, I thought I would go "audio" with a recording from Charlie Andrews, IBM director ofproduct marketing for IBM System Storage:
If you are unable to listen, you can read the details for each here:
Also today IBM announced special 5-packs for LTO-4 and DDS-6 tape cartridge media. Here is the Press Release.

If you are ever down in Sao Paulo, Brazil, may I suggest not drinking "American amounts" of their "Brazilian Coffee". The coffee here is "robust", to say the least.
Yesterday, my blog focused on IBM iSCSI offerings that were announced in August.Also announced earlier this month, the Integrated Removable Media Manager (IRMM) on System zhas been years in the making.IRMM is a new robust systems management product for Linux® on IBM System z™ that manages open system media in heterogeneous distributed environments and virtualizes physical tape libraries. IRMM combines the capacity of multiple heterogeneous libraries into a single reservoir of tape storage that can be managed from a central point.By providing an integrated solution with the opportunity for both mainframe z/OS DFSMSrmm and distributed Tivoli® Storage Manager™ environments to be managed by IRMM, System z can now be a hub for the management of removable media.
The people who thought the "Mainframe is obsolete", and those that thought "Tape is dead", are both proven wrong again with this announcement. People are looking to deploy robust tape automation for backup and archive, and this convergence with mainframe makes perfect sense by providing business value that extends to other distributed systems.
