Tivoli Storage Manager for z/OS Media 6.3

I mentioned this one already in a previous post as part of the October 12 annouInfocncements. So, I thought I'll take a look at the IBM site for some more information on this, but I must say it was a bit disappointing. When you go to the Tivoli Storage Manager page, there's not even a reference to TSM for z/OS Media.

But when you want some more content, there's the InfoCenter with a couple of entries ('What's New' and 'TSM for z/OS Media Overview'). And for those of you who prefer a .pdf there's the 'Installation and Configuration guide' which you can find over here. But if you want a good introduction, you can take a look at this presentation Bart Claeys (IBM Belgium) gave at the Total Solutions Event in September in Brussels. Mind you, it was still a preview at the time, but I haven't found any more recent, public presentations about this.

For the lazy ones, I mean, for those with limited time, let me summarize some of it. The deal was that TSM V6 was never announced for z/OS leaving many people with sometimes quite large investments in FICON attached material like Tape Libraries and Virtualisation Engines in the cold. So you had to convert to another platform that was not able to connect to your FICON attached equipment.

Well now, TSM for z/OS Media is the missing link between both. You can now migrate to V6 but you can still write your data via z/OS to your FICON attached equipment. The concept is also "designed to allow the tape volume and stored data that was previously inventoried by the Tivoli Storage Manager for z/OS V5.5 server remain accessible on the z/OS system by the Tivoli Storage Manager V6.3 server on AIX or Linux for System z without having to move the tape volume from the z/OS managed tape library" (quote from the announcement letter).

This is a representation of how TSM for z/OS 5.5 operates

TSM for z/OS V5 takes care of

• Database functions: nodes, administrators, policy, tracking of data
• Communication with clients, Admin Center, other TSM servers
• Performs the I/O to FICON (and other) tape and disk

And above is the new situation, with TSM V6 server on AIX or Linux on z taking over most or all of the functionalities of TSM for z/OS V5. But instead of attaching to storage devices, it can also communicate with the TSM for z/OS Media. So you can preserve your previous FICON investments. There are more details in the presentation, for those who are interested.

I'll just give you a quick overview of the migration path

• Install TSM 6.3 server on AIX or zSeries Linux
• Install z/OS media server
• TSM for z/OS 5.5 server move all storage to TAPE
• Extract and Load : TSM utility extracts records from TSM 5.5 z/OS database and loads into TSM v6 database on AIX or zLinux. There is no need to migrate data already written to tape by TSM on z/OS. So you can preserve stored archive (and backup) data avoiding time-consuming migration of data from existing storage pools.
• Begin backups with new distributed server
• Take TSM for z/OS 5.x server off line

Last but not least : pricing. Well, the goal seems to be to make this a cost neutral operation from a licensing perspective. I know, pretty vague, but I have no experience with it for the moment. So, do contact IBM or your local BP to sort this out with you, because it also seems to depend on the type of licensing you have now.

Planned availability date : November 11, 2011.

2011Q4 IBM mainframe announcements

A lot of interesting mainframe news was announced this week. I'm going to give you a brief overview of the announcements before I go into more details in some following posts. You shouldn't expect those to arrive before next week as I'm off to the IBM briefing center at Montpellier for the rest of the week - attending the Oracle on System z event.

The eye-catcher is of course Windows on zBX, but there's really much more. I'll start by giving you the titles of the announcements, the links and some brief information. Just to tease you for what's coming !


IBM DB2 Analytics Accelerator for z/OS , V2.1 enables a new class of business intelligence and data warehousing workloads for the IBM System z platform (ZP11-0546)
IDAA (yes, we needed another acronym) is the successor of ISAOpt (euh, IBM Smart Analytics Optimizer). It is based on Netezza technology and it should deliver an even far better performance. For the rest, it is implemented as transparantly as ISAOpt for DB2 for z/OS applications. What I find a bit annoying here is that it is not integrated into the zBX and therefore it is not managed by the Unified Resource Manager.


IBM z/VSE V5.1 - 64-bit virtual for future workloads (ZP11-0560)
z/VSE 5.1 is designed to

• "Provide 64-bit virtual addressing for workload growth or new applications.
• Introduce an architectural level set (ALS) that requires IBM System z9 or later.
• Exploit innovative IBM zEnterprise technology.
• Exploit enhanced IBM System Storage options.
• Offer new networking functions for more connectivity options.
• Provide Connector enhancements for high availability".

zEnterprise further extends hybrid computing with support for Microsoft Windows and other enhancements (ZG11-0275)
zHPF enhancements, APIs for the Unified Resource Manager, GDPS improvements and a lot more. But of course focus will mainly be on "Microsoft™ Windows™ on select IBM BladeCenter® HX5 (7873) blades installed in the zBX".


IBM z/VM V6.2 - Accelerate the journey to smarter computing with multi-system virtualization and virtual server mobility (ZP11-0499)
This had been a statement of direction for some time. Well, here it is now : "Multi-system virtualization clustering technology allowing up to four z/VM instances to be clustered in a Single System Image (SSI)". This also implies "Live Guest Relocation to move Linux™ virtual servers without disruption to the business, helping to avoid planned outages"


IBM Tivoli Storage Manager for z/OS Media V6.3 and IBM Tivoli Storage Manager Extended Edition for z/OS Media V6.3 enable FICON attached device access for IBM Tivoli Storage Manager V6.3 Server on AIX and Linux on System z (ZP11-0465)
I like this one as well. It took some time to deliver but it's finally there. Lots of customers were running TSM for z/OS and invested in FICON coupled tape or DASD solutions. But then it was announced that TSM V6 would no longer run on z/OS. So you had to convert to another platform that was not able to connect to your FICON attached equipment. So, this TSM for z/OS Media is the missing link between both. You can now migrate to V6 but you can still write your data via z/OS to your FICON attached equipment. The concept is also "designed to allow the tape volume and stored data that was previously inventoried by the Tivoli Storage Manager for z/OS V5.5 server remain accessible on the z/OS system by the Tivoli Storage Manager V6.3 server on AIX or Linux for System z without having to move the tape volume from the z/OS managed tape library".
