Veritas Cluster and Veritas Volume Manager
Veritas Volume Manager or VxVM by Symantec is a storage management subsystem that allows you to manage physical disks as logical devices called volumes. A VxVM volume appears to applications and the operating system as a physical disk partition device on which file systems, databases and other managed data objects can be configured.
Veritas Cluster.com presents VxVM by Symantec.
VxVM provides easy-to-use online disk storage management for computing environments and Storage Area Network (SAN) environments. By supporting the Redundant Array of Independent Disks (RAID) model, VxVM can be configured to protect against disk and hardware failure, and to increase I/O throughput. Additionally, VxVM provides features that enhance fault tolerance and fast recovery from disk failure.
VxVM overcomes physical restrictions imposed by hardware disk devices by providing a logical volume management layer. This allows volumes to span multiple disks.
VxVM provides the tools to improve performance and ensure data availability and integrity. You can also use VxVM to dynamically configure disk storage while the system is active.
