Pinned topic zNext - One Box to Rule them All?

‏2010-07-02T14:21:14Z |
I expect everyone is excited about the July 22 announcement. Will zNext include AIX, Teradata, even Windows?

I've blogged about it here including an amusing illustration, I'd be delighted if you were to visit and give me your thoughts. Or follow this comment, it would be good to get Destination z a bit busier.

    Alan, I assume you're referring to the z196-announcements (and all related stuff)? Fascinating. Almost too good to be true. Multi-platform, single management, one single image. And all this thru the magic of this "Universal Resource Manager" (zBX?).

    I've been trying to get hold of docs that tell me just how this thing (URM / zBX) does it, but couldn't find anything. It actually does exist, doesn't it? I mean, it's GA?

    Would be nice if you could point me to something that would elaborate on how this stuff is actually done, how the zBX (URM?) actually works. I don't expect any in-depth technical details (although...), but would appreciate something at a greater level of detail than the announcement.

      Hi Willem
      There is some more high level stuff here on the zEnterprise Unified Resource Manager (zManager) here
      http://www-03.ibm.com/systems/z/hardware/zenterprise/zmanager.html

      The best technical resources so far are the draft Redbooks such as this one
      http://www.redbooks.ibm.com/redpieces/abstracts/sg247832.html?Open

      More will follow but yes, zManager is GA, and is a development of Systems Director, which has been around for a while, redbook here
      http://www.redbooks.ibm.com/abstracts/sg247694.html?Open

      Hope this helps. Follow my new dW blog here for more...
      https://www.ibm.com/developerworks/mydeveloperworks/blogs/zSecurity/?lang=en
      And yes, zEnterprise is very exciting!
      Thanks

        Alan,

        Thanks! These docs look just like what I've been looking for.

        By the way, your "One Box to Rule them All", it does make you think of something like:

        One Box to find them
        One Box to bring them all
        and in the Darkness bind them

        Mount Doom is located in Armonk nowadays?

            Alan,

            A couple of questions:

            [1] I trust that RMF is aware of the zBX? I mean, suppose the zBX does speed up DB2 transactions and RMF isn't aware of its existence, wouldn't this give you a completely erroneous impression of the DB2-environment? Does the zBX appear in any other monitor, be it a DB2 internal one or not?

            [2] How does IBM intend this zBX to be used? Thru an API? I mean, does IBM intend to allow application-developers to "directly" use the zBX in their applications? More or less like using ZIIPs or ZAAPs?

              Willem,

              Alan asked me to contribute to this thread, so here goes.

              It's probably worth commenting first that the blades running in the zBX are simply running whatever operating system is supported for that blade, under a virtualisation environment. So with the Power blades they will be running AIX on Power/VM and when the x86 blades appear* they'll be running Linux. You can see their basic performance and status information within URM, but as far as application monitoring is concerned they are just targets for your existing monitoring solution (Tivoli etc). For the IBM System Analytics Optimiser blades (which I infer you are discussing) these are effectively accelerators for existing DB2 on z/OS queries and are essentially a "black box" as far as external monitoring is concerned.

              So, to answer you questions:
              (1) RMF is not aware of the zBX either as a general purpose blade environment or as the Analytics Optimiser. Of course your DB2 monitoring of query performance will show extreme performance improvement for queries that are directed to the Analytics Optimiser, and this fact may be reflected in your RMF statistics.
              (2) The Analytics Optimiser blades do have similar "operational" characteristics to zAAPs and zIIPs, there is no API and their usage is controlled by DB2 - and loading the data to them for queries will be a periodic function. The other blades types provide a virtualised environment (AIX, Linux) on which to run existing or new applications which ideally benefit from proximity to your System z conventional (or Linux on System z) workloads - say for example application server front ends to database or J2EE server running on z/OS or Linux on z.

              I've only scratched the surface here - I'm sure the manuals that Alan has recommended can assist with further details
