IBM had over a dozen storage-related announcements this week. This is my third and final part in my series to provide a quick overview of the announcements.
- IBM Tivoli® Storage Manager v6.3
IBM Tivoli Storage Manager is market-leading software that provides not just backup, but also HSM and archive capabilities across a wide variety of operating systems. Originally developed in the IBM Almaden Research Center, it then moved about 15 years ago to Tucson to become a commercial product.
The new TSM v6.3 introduces site-to-site hot-standby disaster recovery feature that replicates the TSM meta data and data for fast recovery. The maximum number of objects supported has doubled to four billion. Reporting has been enhanced using technologies borrowed from IBM Cognos. Lastly, a feature on Tivoli Storage Productivity Center has been carried forward to deploy and update agents on the various clients.
For more details, see fellow IBM blogger Richard Vining's post on
[TSM v6.3 Announcements]
- IBM Tivoli Storage FlashCopy® Manager v3.1
IBM Tivoli Storage FlashCopy Manager coordinates application-aware backups through the use of point-in-time copy services such as FlashCopy or Snapshot on various IBM and non-IBM disk systems. The versions can remain on disk, or optionally processed by Tivoli Storage Manager to move them to external storage such as tape for added protection.
There will always be a spot in my heart for this product, as the method to use FlashCopy for application-aware backups on the mainframe was my 19th patent, and subsequently delivered as a series of enhancements to DFSMS over the past decade on the z/OS operating system. It is good to see this innovation has "jumped over" to distributed systems.
The new FlashCopy Manager v3.1 adds support for HP-UX and VMware, expands support for IBM DB2 and Oraqcle databases, and introduces an interface for custom business applications.
For more details, see fellow IBM blogger Del Hoobler's post on
[TSM FlashCopy Manager v3.1 Announcements].
- IBM Tivoli Storage Manager for Virtual Environments v6.3
TSM for VE is a new addition to the TSM family, focused on being able to coordinate hypervisor-aware data protection. Initially it supports VMware, but IBM has plans to support a variety of other server virtualization hypervisors as well, as over 40 percent of companies run two or more hypervisors in their data center.
The new TSM for VE v6.3 adds a VMware vCenter plug-in, and support for hardware-based disk snapshots.
- IBM Tivoli Storage Productivity Center v4.2.2
A long time ago, I was the chief architect IBM Tivoli Storage Productivity Center v1, now we are already up to v4.2.2 release!
IBM has added enhanced reporting based on IBM Cognos technology, including storage tiering analysis reports (STAR). Few companies keep all of their storage tiers in a single disk system. Rather, they have different boxes, and often from different vendors. IBM's Productivity Center can report on both IBM and non-IBM disk systems. New this release is support for the internal disks of the Storwize V7000 midrange disk system.
Productivity Center's "SAN Planner" has been enhanced to consider XIV replication criteria. This SAN Planner helps clients decide where to carve LUNs, and to make sure they pick the right place given all of the criteria such as remote copy replications.
Last year, we introduced Productivity Center for Disk Midrange Edition (MRE) which to offer lower price when you are only managing midrange disk systems DS5000, DS3000, Storwize V7000 and SVC managing these. This was so successful, that we now have TPC Select, which is basically Productivity Center Standard Edition (SE) for these midrange disk systems.
Whew! I have already heard from some of my readers to slow down, that this is too much information to deal with all at once. IBM has tried everything from having just a few announcements nearly every Tuesday, to having huge launches every two to three years, and settled in the middle with announcements about four to five times per year.

Continuing my coverage of the [IBM System Storage Technical University 2011], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This year, we had two, one for System x called "Ask the eXperts", and one for System Storage called "Storage Free-for-All". This post covers the latter.
(Disclaimer: Do not shoot the messenger! We had a dozen or more experts on the panel, representing System Storage hardware, Tivoli Storage software, and Storage services. I took notes, trying to capture the essence of the questions, and the answers given by the various IBM experts. I have spelled out acronyms and provided links to relevant materials. The answers from individual IBMers may not reflect the official position of IBM management. Where appropriate, my own commentary will be in italics.)
Are there any plans to improve the use of BRMS [Backup Recovery and Media Services for IBM i
] with [Tivoli Storage Manager (TSM)
It should be against the law to connect these two together. IBM has no plans to make any further improvements.
When will [IBM BladeCenter S
] support 2.5-inch drives?
You are in the wrong session! Go to "Ask the eXperts" session next door!
The TSM GUI sucks! Are there any plans to improve it?
Yes, we are aware that products like IBM XIV have raised the bar for what people expect from graphical user interfaces. We have plans to improve the TSM GUI. IBM's new GUI for the SAN Volume Controller and Storwize V7000 has been well-received, and will be used as a template for the GUIs of other storage hardware and software products. The GUI uses the latest HTML5, Dojo widgets and AJAX technologies, eliminating Java dependencies on the client browser.
Can we run the TSM Admin GUI from a non-Windows host?
IBM has plans to offer this. Most likely, this will be browser-based, so that any OS with a modern browser can be used.
As hard disk drives grow larger in capacity, RAID-5 becomes less viable. What is IBM doing to address this?
IBM is aware of this problem. IBM offers RAID-DP on the IBM N series, RAID-X on the IBM XIV, and RAID-6 on its other disk systems.
TPC licensing is outrageous! What is IBM going to do about it?
IBM introduced the [Tivoli Storage Productivity Center for Disk Midrange Edition (MRE)] to help address the cost when Small and Medium-sized Businesses managing SVC, Storwize V7000, DS5000 and DS3000 disk systems.
What is the adoption rate of IBM Easy Tier?
About 25 percent of DS8000 disk systems have SSD installed. Now that IBM DS8000 Easy Tier supports "any two" tiers, roughly 50 percent of DS8000 now have Easy Tier activated. No idea on how Easy Tier has been adopted on SVC or Storwize V7000.
We have an 8-node SVC cluster, should we put 8 SSD drives into a single node-pair, or spread them out?
We recommend putting a separate Solid-State Drive in each SVC node, with RAID-1 between nodes of a node-pair. By separating the SSD across I/O groups, you can reduce node-to-node traffic.
How well has SVC 6.2 been adopted?
The inventory call-home data is not yet available. The only SVC hardware model that does not support this level of software was the 2145-4F2 introduced in 2003. Every other model since then can be updated to this level.
Will IBM offer 600GB FDE drives for the IBM DS8700?
Currently, IBM offers 300GB and 450GB 15K RPM drives with the Full-Disk Encryption (FDE) capability for the DS8700, and 450GB and 600GB 10K RPM drives with FDE for the IBM DS8800. IBM is working with its disk suppliers to offer FDE on other disk capacities, and on SSD and NL-SAS drives as well, so that all can be used with IBM Easy Tier.
Is there a reason for the feature lag between the Easy Tier capabilities of the DS8000, and that of the SVC/Storwize V7000?
We have one team for Easy Tier, so they implement it first on DS8000, then port it over to SVC/Storwize V7000.
Does it even make sense to have separate storage tiers, especially when you factor in the cost of SVC and TPC to make it manageable?
It depends! We understand this is a trade-off between cost and complexity. Most data centers have three or more storage tiers already, so products like SVC can help simplify interoperability.
Are there best practices for combining SVC with DS8000? Can we share one DS8000 system across two or more SVC clusters?
Yes, you can share one DS8000 across multiple SVC clusters. DS8000 has auto-restripe, so consider having two big extent pools. The queue depth is 3 to 60, so aim to have up to 60 managed disks on your DS8000 assigned to SVC. The more managed disks the better.
The IBM System Storage Interopability Center (SSIC) site does not seem to be designed well for SAN Volume Controller.
Yes, we are aware of that. It was designed based on traditional Hardware Compatability Lists (HCL), but storage virtualization presents unique challenges.
How does the 24-hour learning period work for IBM Easy Tier? We have batch processing that runs from 2am to 8am on Sundays.
You can have Easy Tier monitor across this batch job window, and turn Easy Tier management between tiers on and off as needed.
Now that NetApp has acquired LSI, is the DS3000 still viable?
Yes, IBM has a strong OEM relationship with both NetApp and LSI, and this continues after the acquisition.
If have managed disks from a DS8000 multi-rank extent pool assigned to multiple SVC clusters, won't this affect performance?
Yes, possibly. Keep managed disks on seperate extent pools if this is a big concern. A PERL script is available to re-balance SVC striped volumes as needed after these changes.
Is the IBM [TPC Reporter
] a replacement for IBM Tivoli Storage Productivity Center?
No, it is software, available at no additional charge, that provides additional reporting to those who have already licensed Tivoli Storage Productivity Center 4.1 and above. It will be updated as needed when new versions of Productivity Center are released.
We are experiencing lots of stability issues with SDD, SDD-PCM and SDD-DSM multipathing drivers. Are these getting the development attention they deserve?
IBM's direction is to shift toward native OS-based multipathing drivers.
Is anyone actually thinking of deploying public cloud storage in the near-term?
A few hands in the audience were raised.
None of the IBM storage devices seem to have [REST API
]. Cloud storage providers are demanding this. What are IBM plans?
IBM plans to offer REST on SONAS. IBM uses SONAS internally for its own cloud storage offerings.
If you ask a DB2 specialist, an AIX specialist, and a System Storage specialist, on how to configure System p and System Storage for optimal performance, you get three different answers. Are there any IBMers who are cross-functional that can help?
Yes, for example, Earl Jew is an IBM Field Technical Support Specialist (FTSS) for both System p and Storage, and can help you with that.
Both Oracle and Microsoft recommend RAID-10 for their applications.
Don't listen to them. Feel free to use RAID-5, RAID-6 or RAID-X instead.
Resizing SVC source volumes forces ongoing FlashCopy or Metro Mirror relatiohships to be stopped. Does IBM plan to address this?
Currently, you have to stop, resize both source and target, then start the relationship again. Consider getting IBM Tivoli Storage Productivity Center for Replication (TPC-R).
What ever happened to IBM [Grid Medical Archive Solution (GMAS)
IBM continues to support this for exising clients. For new deployments, IBM offers SONAS and the Information Archive (IA).
When will I be able to move SVC volumes between I/O groups?
You can today, but it is disruptive to the operating system. IBM is investigating making this less disruptive.
Will XIV ever support the mainframe?
It does already, with support for both Linux and z/VM today. For VSE support, use SVC with XIV. For those with the new zBX extension, XIV storage can be used with all of the POWER and x86-based operating systems supported. IBM has no plans to offer direct FICON attachment for z/OS or z/TPF.
Not a question - Kudos to the TSM and ProtecTIER team in supporting native IP-based replication!
When will IBM offer POWER-based models of the XIV, SVC and other storage devices?
IBM's decision to use industry-standard x86 technology has proven quite successful. However, IBM re-looks at this decision every so many years. Once again, the last iteration determined that it was not worth doing. A POWER-based model might not beat the price/performance of current x86 models, and maintaining two separate code bases would hinder development of new innovations.
We have both System i and System z, what is IBM doing to address the fact that PowerHA and GDPS are different?
IBM TPC-R has a service offering extension to support "IBM i" environments. GDPS plans to support multi-platform environments as well.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.

Yes, it's Tuesday, and that means more IBM Announcements! A lot was announced today, so I have selected an eclectic mix for your enjoyment.
- Microsoft Windows support on IBM Mainframes
Last year's announcement of the new IBM zEnterprise included the zEnterprise BladeCenter Extention (zBX) which could run POWER7 and x86 operating systems, but managed by the mainframe's overall Unified Resource Manager. Initially, this was intended for AIX and Linux-x86, but today, IBM [announced a statement of general direction to support Microsoft Windows] on the zBX extension by end of this year. Of course, the standard disclaimer applies: All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Any reliance on these statements of general direction is at the relying party's sole risk and will not create liability or obligation for IBM.
- New 15K RPM drives for IBM Storwize V7000
Last October, when IBM introduced the Storwize V7000, it offered both large (3.5 inch) and small form factor (2.5 inch) drives. Unfortunately, a few people were upset that there were no 15K RPM drives for the small form factor models. There were SSD and 10K RPM drives, but nothing in between. Today, IBM [announced new 15K RPM drives of 146GB capacity] have been qualified for both the controller and expansion drawers.
- New RVU licensing for IBM Tivoli products
IBM [announced it is changing over to this new RVU licensing model], from the previous PVU license, based on processor value units. What is an RVU? An RVU is a unit of measure by which the program can be licensed. RVU Proofs of Entitlement (PoE) are based on the number of units of a specific resource used or managed by the program. This makes sense, resource management software should be charged by the amount of resources you manage, not the size of the server the software runs on. This change also enables running on server virtualization and live movement of VM guest images from one type of host machine to another.
If you are contemplating a visit to an IBM [Executive Briefing Center], then April and May is a great time to come to Tucson. The weather is ideal here. The cold snap appears to be over, and spring is in the air!

It's Tuesday again, and that means one thing.... IBM Announcements! On the heels of [last week's announcements], IBM announced some additional products of interest to storage administrators.
- IBM Information Archive
Back in 2008, IBM [unveiled the Information Archive]. This storage solution provides automated policy-based tiering between disk and tape, with non-erasable non-rewriteable enforcement to protect against unethical tampering of data. The initial release supported [both files and object storage], with support for different collections, each with its own set of policies for management. However, it only supported NFS initially for the file protocol. Today, IBM announces the addition of CIFS protocol support, which will be especially helpful in healthcare and life sciences, as much of the medical equipment is designed for CIFS protocol storage.
Also, Information Archive will now provide a full index and search feature capability to help with e-Discovery. Searches and retrievals can be done in the background without disrupting applications or the archiving operations.
To learn more, read the [announcement letter].
- IBM Tivoli Storage Manager
IBM Tivoli Storage Manager for Virtual Environments V6.2 extends capabilities that currently exist in IBM Tivoli Storage Manager. TSM backup/archive clients run fine on guest operating systems, but now this new extension improves backup for VMware environments. TSM provides incremental block-level backups utilizing VMware's vStorage APIs for Data Protection and Changed Block Tracking features.
To minimize impact to the VMware host, TSM for VE make use of non-disruptive snapshots and offload the backup processing to a vStorage backup server. This supports file-level recovery, volume-level recovery, and full VM recovery. Of course, since it is based on TSM v6, you get advanced storage efficiency features such as compression and deduplication to minimize consumption of disk storage pools.
To learn more, see the [announcement letter].
- IBM Tivoli Monitoring for Virtual Servers V6.2.3
IBM Tivoli Monitor has been extended to support virtual servers, including VMware, Linux KVM, and Citrix XenServer. This can help with capacity planning, performance monitoring, and availability. Tivoli Monitor will help you understand the relationships between physical and virtual resources to help isolate problems to the correct resource, reducing the time it takes for debug issues between servers and storage. See the
Next week is [IBM Pulse2011 Conference] in Las Vegas, February 27 to March 2. Sorry, I don't plan to be there this year. It is looking to be a great conference, with fellow inventor Dean Kamen as the keynote speaker. For a blast from the past, read my blog posts from Pulse2008 [Main Tent sessions] and [Breakout sessions].

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

Well, it's Tuesday, and you know what that means! IBM Announcements!
This week, IBM announces its latest versions of IBM [Tivoli Storage Productivity Center v4.2] and [Tivoli Storage Productivity Center for Replication on System z v4.2]. I was the original lead architect for Productivity Center back in the version 1 and version 2 days, and am proud to see my little baby has grown up to be a fine young citizen. Analysts recognize IBM Tivoli Storage Productivity Center as one of the top three best SRM products currently in the marketplace. Here are the key highlights:
- Storage Resource Agent
The "Storage Resource Agent" introduced for Linux, AIX and Windows in v4.1 is a lightweight agent, written in native "C" language instead of Java, to avoid all the resources that Java consumes. In this release, it is now supported for HP-UX and Solaris, and adds file level and database level storage resource management (SRM) reporting for all five platforms.
For new customer deployments, this will eliminate all the pain setting up a "Common Agent Manager". The Productivity Center server will send out the agent, the agent collects the data, and can then optionally uninstall itself. In this manner, you always have the latest version of the code collecting the data. For those with Common Agent Manager already installed, you can continue running as is, or slowly transition over to the new lightweight agent methodology.
- Full support for IBM XIV Storage System
IBM XIV® Storage System support updated to include provisioning, data path explorer and performance management reporting. Before this release, Productivity Center could only discover and provide rudimentary capacity information for XIV systems. Now you can carve LUNs and monitor XIV disk performance just like you can with most other disk systems.
- Storage Area Network (SAN) configuration planning
For those who have both Productivity Center Standard Edition (SE) and Productivity Center for Replication, the SAN Config Planner is now "replication-aware" and will add LUNs to existing copy sessions, or create new copy sessions, and ensure that the devices chosen meet the appropriate criteria.
- HyperSwap™ for the IBM AIX® environment
On z/OS mainframes, if you experience an outage on a storage system, Productivity Center for Replication (TPC-R) can automatically swap to the synchronous mirror copy without disruption to the operating system or application. Now, IBM has extended this awesome feature to the AIX platform for high availability in POWER-based server environments.
- Detailed Session Reporting for Global Mirror
Before, TPC-R enforced the notion of only one Global Mirror master per storage system. Now, TPC-R v4.2 is capable of supporting multiple Global MIrror sessions, and provide more detailed session reporting for these environments. This can be useful if for some unknown reason the bits are not being shoveled from point A to point B, and you need to do some "problem determination".
- SVC Incremental FlashCopy
Productivity Center for Replication now adds support for the "Incremental" feature of SVC FlashCopy. While FlashCopy requests are processed instantaneously, there is background processing required that can consume cycles. Incremental processing keeps track of what changed since the last FlashCopy, and minimizes this behind-the-scenes overhead.
- Integrated Distributed Disaster Recovery manager
IBM Tivoli System Automation Application Manager [TSA-AM] can now integrate with TPC-R to provide application-aware disaster recovery capability. This can coordinate between IBM Tivoli System Automation for Multiplatforms [TSA-for-MP], IBM HACMP/PowerHA, as well as other clustering products like Microsoft Cluster Services (MSCS) and Veritas Cluster Services on Solaris. When TSA-AM detects an outage, it can notify Globally Dispersed Parallet Sysplex Distributed Cluster Management (GDPS-DCM) to take action. This integration was actually completed with TPC v4.1 back in April, but got buried deep inside our big storage launch, so I bring it up again as a gentle reminder that IBM offers the best end-to-end management on the planet.
At last month's Storage University, I presented an overview of [Tivoli Storage Productivity Center v4.1]. Many of the questions were along the lines of "When will TPC do xyz?" and all I could answer was "Soon" since I knew they would be delivered with this TPC v4.2 release, but I couldn't provide any more details than that at the time.

Continuing my coverage of the annual [2010 System Storage Technical University], I participated in the storage free-for-all, which is a long-time tradition, started at SHARE User Group conference, and carried forward to other IT conferences. The free-for-all is a Q&A Panel of experts to allow anyone to ask any question. These are sometimes called "Birds of a Feather" (BOF). Last year, they were called "Meet the Experts", one for mainframe storage, and the other for storage attached to distributed systems. This year, we had two: one focused on Tivoli Storage software, and the second to cover storage hardware. This post provides a recap of the Storage Hardware free-for-all.
The emcee for the event was Scott Drummond. The other experts on the panel included Dan Thompson, Carlos Pratt, Jack Arnold, Jim Blue, Scott Schroder, Ed Baker, Mike Wood, Steve Branch, Randy Arseneau, Tony Abete, Jim Fisher, Scott Wein, Rob Wilson, Jason Auvenshine, Dave Canan, Al Watson, and myself, yours truly, Tony Pearson.
What can I do to improve performance on my DS8100 disk system? It is running a mix of sequential batch processing and my medical application (EPIC). I have 16GB of cache and everything is formatted as RAID-5.
We are familiar with EPIC. It does not "play well with others", so IBM recommends you consider dedicating resources for just the EPIC data. Also consider RAID-10 instead for the EPIC data.
How do I evaluate IBM storage solutions in regards to [PCI-DSS
Well, we are not lawyers, and some aspects of the PCI-DSS requirements are outside the storage realm. In March 2010, IBM was named ["Best Security Company"] by SC Magazine, and we have secure storage solutions for both disk and tape systems. IBM DS8000 and DS5000 series offer Full Disk Encryption (FDE) disk drives. IBM LTO-4/LTO-5 and TS1120/TS1130 tape drives meet FIPS requirements for encryption. We will provide you contact information on an encryption expert to address the other parts of your PCI-DSS specific concerns.
My telco will only offer FCIP routing for long-distance disk replication, but my CIO wants to use Fibre Channel routing over CWDM, what do I do?
IBM XIV, DS8000 and DS5000 all support FC-based long distance replication across CWDM. However, if you don't have dark fiber, and your telco won't provide this option, you may need to re-negotiate your options.
My DS4800 sometimes reboots repeatedly, what should I do.
This was a known problem with microcode level 760.28, it was detecting a failed drive. You need to replace the drive, and upgrade to the latest microcode.
Should I use VMware snapshots or DS5000 FlashCopy?
VMware snapshots are not free, you need to upgrade to the appropriate level of VMware to get this function, and it would be limited to your VMware data only. The advantage of DS5000 FlashCopy is that it applies to all of your operating systems and hypervisors in use, and eliminates the consumption of VMware overhead. It provides crash-consistent copies of your data. If your DS5000 disk system is dedicated to VMware, then you may want to compare costs versus trade-offs.
Any truth to the rumor that Fibre Channel protocol will be replaced by SAS?
SAS has some definite cost advantages, but is limited to 8 meters in length. Therefore, you will see more and more usage of SAS within storage devices, but outside the box, there will continue to be Fibre Channel, including FCP, FICON and FCoE. The Fibre Channel Industry Alliance [FCIA] has a healthy roadmap for 16 Gbps support and 20 Gbps interswitch link (ISL) connections.
What about Fibre Channel drives, are these going away?
We need to differentiate the connector from the drive itself. Manufacturers are able to produce 10K and 15K RPM drives with SAS instead of FC connectors. While many have suggested that a "Flash-and-Stash" approach of SSD+SATA would eliminate the need for high-speed drives, IBM predicts that there just won't be enough SSD produced to meet the performance needs of our clients over the next five years, so 15K RPM drives, more likely with SAS instead of FC connectors, will continue to be deployed for the next five years.
We'd like more advanced hands-on labs, and to have the certification exams be more product-specific rather than exams for midrange disk or enterprise disk that are too wide-ranging.
Ok, we will take that feedback to the conference organizers.
IBM Tivoli Storage Manager is focused on disaster recovery from tape, how do I incorporate remote disk replication.
This is IBM's Unified Recovery Management, based on the seven tiers of disaster recovery established in 1983 at GUIDE conference. You can combine local recovery with FastBack, data center server recovery with TSM and FlashCopy manager, and combine that with IBM Tivoli Storage Productivity Center for Replication (TPC-R), GDOC and GDPS to manage disk replication across business continuity/disaster recovery (BC/DR) locations.
IBM Tivoli Storage Productivity Center for Replication only manages the LUNs, what about server failover and mapping the new servers to the replicated LUNs?
There are seven tiers of disaster recovery. The sixth tier is to manage the storage replication only, as TPC-R does. The seventh tier adds full server and network failover. For that you need something like IBM GDPS or GDOC that adds this capability.
All of my other vendor kit has bold advertising, prominent lettering, neon lights, bright colors, but our IBM kit is just black, often not even identifying the specific make or model, just "IBM" or "IBM System Storage".
IBM has opted for simplified packaging and our sleek, signature "raven black" color, and pass these savings on to you.
Bring back the SHARK fins!
We will bring that feedback to our development team. ("Shark" was the codename for IBM's ESS 800 disk model. Fiberglass "fins" were made as promotional items and placed on top of ESS 800 disk systems to help "identify them" on the data center floor. Unfortunately, professional golfer [<a href="http://www.shark.com/">Greg Norman</a>] complained, so IBM discontinued the use of the codename back in 2005.)
Where is Infiniband?
Like SAS, Infiniband had limited distance, about 10 to 15 meters, which proved unusable for server-to-storage network connections across data center floorspace. However, there are now 150 meter optical cables available, and you will find Infiniband used in server-to-server communications and inside storage systems. IBM SONAS uses Infiniband today internally. IBM DCS9900 offers Infiniband host-attachment for HPC customers.
We need midrange storage for our mainframe please?
In addition to the IBM System Storage DS8000 series, the IBM SAN Volume Controller and IBM XIV are able to connect to Linux on System z mainframes.
We need "Do's and Don'ts" on which software to run with which hardware.
IBM [Redbooks] are a good source for that, and we prioritize our efforts based on all those cards and letters you send the IBM Redbooks team.
The new TPC v4 reporting tool requires a bit of a learning curve.
The new reporting tool, based on Eclipse's Business Intelligence Reporting Tool [BIRT], is now standardized across the most of the Tivoli portfolio. Check out the [Tivoli Common Reporting] community page for assistance.
An unfortunate side-effect of using server virtualization like VMware is that it worsens management and backup issues. We now have many guests on each blade server.
IBM is the leading reseller of VMware, and understands that VMware adds an added layer of complexity. Thankfully, IBM Tivoli Storage Manager backups uses a lightweight agent. IBM [System Director VMcontrol] can help you manage a variety of hypervisor environments.
This was a great interactive session. I am glad everyone stayed late Thursday evening to participate in this discussion.

Well, it's Tuesday, and you all know what that means... IBM announcements!
This week, IBM announced the IBM Tivoli Storage Productivity Center for Disk Midrange Edition, affectionately referred to as "MRE". This is basically TPC for Disk but with two key differences:
- A special license that covers only DS3000, DS4000, DS5000 series, whether natively attached or virtualized behind SAN Volume Controller.
- A new pricing model based on the number on controllers and drawers, rather than by TB managed. For example, if you have a DS5300 and two expansion drawers, then you pay for three units of MRE. As you upgrade from smaller capacity disks to larger capacity disks, your license costs won't increase. This eliminates the quarterly hassle to "true up" your software licenses to match actual capacity that is required on TB-based licensing.
This includes the [new DS3500 model] that was announced last month. This was part of the set of solutions to [help midsized businesses].
A fresh new blogger on the scene, Anthony Vandewerdt (IBM), covers [10 things I like about the IBM DS3500], saving me the trouble.

It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
- Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
- Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
- Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
- Simultaneous Background Tasks
The TSM server has many background administrative tasks:
- Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
- Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
- Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
- Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
- Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.
