Preface

Sun^TM Cluster 2.2 is a software product that supports specific two- to four-node server hardware configurations. It is compatible with the Solaris^TM 2.6 and Solaris 2.7 software environments. When configured properly, the hardware and software together provide highly available data services and parallel database access. Sun Cluster^TM depends upon the mirroring and disk group capabilities and other functionality provided by a volume manager. Sun Cluster supports Solstice DiskSuite^TM, Sun StorEdge Volume Manager^TM (SSVM), and Cluster Volume Manager (CVM).

The Sun Cluster 2.2 System Administration Guide documents the procedures for setting up hardware and installing, configuring, and administering the Sun Cluster software. This book is intended to be used with the hardware and software books listed under "Related Documentation".
