Like at the end of 2012 for the first DS8870 release, then again in the second quarter of this year for important Easy tier updates, the European Storage Support Center in Mainz was one more time the host of ITSO Redbooks residencies for the DS8870 Release 7.2. announced 19 November 2013.
As usual, the Redbooks participants came from various parts of the world -- we hosted guests from Brasil, Canada, Indonesia and USA, together with participating authors from Mainz.
The team has prepared the following material:
Updates of the core DS8870 Architecture and Implementation Redbook, describing the new POWER7+ DS8870 model. POWER7+ comes with more L3 cache, a lot more transistors (2.1 vs. 1.2 bn per core), more cycle speed (GHz), compared to the previous POWER7-based DS8870. The new DS8870 can deliver 20% more max. IOps and has additional optimizations for flash configurations, also a new Business Class line has been introduced for it, and additional drive types. A draft of the book is available here.
The DS8000 Encryption Redpaper has undergone a major overhaul, introducing the IBM Security Key Lifecycle Manager V2.5 as a replacement of the IBM Tivoli Key Lifecycle Manager.
OpenStack is an upcoming hot topic for all our storage landscape, giving a subsystem-independent interface for automated provisioning in cloud environments used by some of our large clients. The DS8870 supports OpenStack Cinder by RPQ now, and we're preparing a Solution Guide for this.
The DS8000 Easy Tier Redpaper has been updated with latest enhancements, like the Cooperative Caching (Easy Tier Server) extending the Easy Tier functionality to Power servers. The paper also documents the new reporting functions that you get with the R7.2 code release for Easy Tier.
