This IBM® Redpapers™ publication is a guide to Copy Services as managed by AIX® in a IBM PowerVM™ virtualized environment. The goal of this paper is to provide step-by-step procedures about how storage subsystem-based Copy Services are accomplished in a virtualized environment and the approach for which they should be adopted.

This paper focuses on Copy Services technology from EMC, Hitachi, and IBM within the following storage subsystem models:
- Hitachi USP V
- IBM DS8300

The storage software products that will be used for the different Copy Services are as follows:
- EMC TimeFinder
