Preface

This redbook provides a foundation for understanding VSE/ESAs support for the IBM 9393 RAMAC Virtual Array (RVA). It covers existing support and the recently available IXFP/SnapShot for VSE/ESA and peer-to-peer remote copy support for the RVA. It also covers using IXFP/SnapShot for VSE/ESA for VSE/VSAM.

The redbook is intended for use by IBM client representatives, IBM technical specialists, IBM Business Partners, and IBM customers who are planning to implement IXFP/SnapShot for VSE/ESA on the RVA.
