IBM's zEnterprise Is A Game Changer For Application-Platform Choice

A quick note on a big announcement today by IBM that is being rolled out as I write this. No, I don't have a crystal ball - my colleague Brad Day and I spent a day in Poughkeepsie in late June for the full scoop - provided under NDA. The announcement is massive, so I'll just lay out the high points and a few of my thoughts on what it means to apps folks. I'll leave the deeper I&O/technical details to Brad and others in subsequent posts and research. My goal here is to get a conversation going here on what it may mean to apps people in your IT shops.

What's in the zEnterprise announcement?

  • It's a new computing environment that unifies Linux, AIX, and z/OS on a new server complex that includes mainframe servers, x86, and Power7 blades under a single set of management software: the zEnterprise Unified Resource Manager (URM).
  • A 10 Gb private data network joins the new z server (z196) and zBX - an ensemble that houses racks of x86 and Power7 blades. It also includes an intra-ensemble network that is physically isolated from all networks, switches, and routers - permitting removal of blade firewalls.
    • One client claims a 12-to-1 reduction in network hops by eliminating blade firewalls.
  • The z196 permits up to 96 Quad-core 5.02 ghz processors, 80 available for customer use, and 112 blades.

What is the impact on applications people and application-platform choice?

zEnterprise is a monster announcement that heralds a long laundry list of improvements - it would be impossible to cover all of the ramifications in a single blog post; however, a brief glimpse of some of the most notable improvements that affect applications folks include (zEnterprise as compared to z10):
