Overview

Veritas 5.1 SP1 suite of products include Base-VxFS, Base-VxVM, OnlineJFS, VxVM-Full, and CVM. Veritas Volume Manager (VxVM) is a storage management subsystem that enables you to manage physical disks as logical devices called volumes. A volume is a logical device that appears to a data management system as a physical disk. Veritas File System (VxFS) is an extent based, intent logging file system that is designed for use in UNIX environments, which require high performance and availability and deal with large volumes of data.

The Cluster Volume Manager (CVM) allows up to 32 nodes in a cluster to simultaneously access and manage a set of disks under VxVM control (VM disks). The same logical view of disk configuration and any changes to this is available on all the nodes. For more information on CVM, see the Managing Serviceguard manual, or the Veritas Volume Manager Administrator's Guide.

The HP Serviceguard Storage Management Suite integrates HP Serviceguard with Symantec’s Veritas Storage Foundation. This combination provides powerful database and storage management capabilities while maintaining the mission-critical reliability that HP Serviceguard customers have come to expect. For more information about HP Serviceguard Storage Management Suite, see HP Serviceguard Storage Management Suite Version A.04.00 Release Notes.
