IBM System Storage DS8000 Easy Tier Server

IBM® Easy Tier® Server is one of several Easy Tier enhancements introduced with the IBM DS8000® Licensed Machine Code 7.7.10.xx.xx. Easy Tier Server is a unified storage caching and tiering solution across IBM AIX® servers and supported direct-attached storage (DAS) flash drives. Easy Tier Server manages placing a copy of the "hottest" volume extents on flash drives attached to an AIX server. Data can be read directly from flash drives local to the application host rather than from cache or disk drives in the DS8870, while maintaining other advanced feature functions.

This IBM Redpaper™ publication explains the Easy Tier Server concept and explores key aspects of its architecture, design, and implementation.

From a more practical standpoint, this publication also contains numerous illustrations and examples that help you set up, manage, and monitor Easy Tier Server.
