Sampling Techdocs - up to May 2014

Here I am again with an overview 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.
  • FAQ : z/OS 2.1 Frequently Asked Question
    This FAQ is a collection of questions that were raised by customers during several presentations on z/OS 2.1 that have been answered by subject matter experts. Too many diverse topics to sum them all up, so just have a look.
  • Technical Document : IBM drives to Storage Systems cheat sheet
    I'm sure I mentioned this one before but here's an update on this one-pager showing the currently offered drive types for current IBM Storage Systems including of course DS8000 and XIV.
    • Tool : IBM Storage Tier Advisory Tool Charting Utility
      You surely know about the DS8000 Storage Tier Advisor Tool (STAT). Data from the monitoring process by Easy Tier  is included in a summary report that you can download to a Windows system. The STAT application allows you to view the data when you point your browser to that file. Now - on top of this - the Charting Utility does exactly what its name says. This Utility will format some of the data provided and create charts like
      • Skew Chart - Workload activity by percentage of capacity
      • Movement Chart - Easy Tier data movement activity
      • Workload Chart - Capacity utilization by extent pool 
    • Technical Document : IBM System Storage Easy Tier Quick Start
      Ok, ok, I'm cheating a bit here, this one is not on Techdocs but I came across it while following a link on the charting utility. "This publication introduces the IBM® System Storage Easy Tier Quick Start, which helps you get started with Easy Tier functions using the IBM System Storage DS Storage Manager". If you have to set up Easy Tier, this is a document you're surely going to like.
    Well that's it for now. And, as I always say : just check them out !
