Sampling Techdocs - November 2011-Janary 2012

Here I am again with another review of interesting TechDocs documents I came across while browsing through the latest publications. If you're completely unfamiliar to Techdocs, here's an introduction to it.
  • White paper : IBM System Storage DS8800 and DS8700 Performance with Easy Tier 3rd Generation
    Easy Tier 3rd generation "further expands Easy Tier to manage hybrid storage pools with up to three tiers including Solid State Drives (SSDs), Enterprise Disks, and Nearline Disks". But the paper is not only for people using hybrid pools : "Auto Rebalance has also been extended to include management of homogenous pools containing only a single tier of storage". Easy Tier 3 is available from DS8000 LIC Release 6.2.
  • Workshop material : WAS z/OS V8 Wildfire Workshop Material
    WebSphere Application Server for z/OS Version 8 was made available in 2011. It has many new features and functions associated with it, including updated open standard application interface specification support. This is the handout material of a 5-unit wildfire workshop on it. Units are 'Introduction and Overview', 'Administrative Model', 'The Split JVM Model', 'Accessing z/OS Data', 'WebSphere Optimized Local Adapters' and Hands-on lab instructions.
  • Technical Document : Using z/VM FBA Emulation in a Second-Level ID
    Starting point : "z/VM can access SCSI disks through the services of an I/O layer known as FBA Emulation, introduced with z/VM 5.1. FBA Emulation was added to z/VM to remove one of the \barriers to entry" for Linux on System z: ECKD DASD. With FBA Emulation, a site with no traditional mainframe installation can install and run z/VM and Linux guests without having to invest in mainframe DASD".
    "The z/VM FBA Emulation feature allows z/VM systems to access and use SCSI-over-FCPdisks via a SAN fabric. FBA Emulation is straightforward to use at a first-level system but complexity arises at second-level. This article presents a review of using FBA Emulation and the alternatives for using these disks in a second-level ID".
Well that's it for now. And, as I always say : just check them out !
