DS8000 Thin Provisioning

An IBM Redpaper publication


Thin provisioning can help by reducing the amount of unused storage typically allocated to applications or users. Thin provisioning, as now available for the DS8000, defers the allocation of actual space on the storage subsystem until when data must effectively be written to disk
This IBM® Redpaper is intended to provide an overall understanding of how Thin Provisioning works on the DS8000. It provides some insights into the function design and its implementation on the DS8000 and contains illustrations for the configuration of thin provisioned volumes from either the DS GUI or the DS CLI.
This paper also includes considerations that will help you decide what applications will effectively benefit from Thin Provisioning and takes you through some scenarios and utilities for migrating from standard to thin provisioned volumes.
