Veritas Volume Manager (VxVM) enables us to manage physical drives as logical devices. Applications and the operating system see a veritas disk/volume as a physical disc with configurable file systems, databases, and other managed data objects.
For computer and Storage Area Network (SAN) systems, VxVM offers simple online disc storage management. In order to boost I/O throughput and safeguard against hardware failure, VxVM can be configured to support the Redundant Array of Independent Disks (RAID) concept. Moreover, VxVM has capabilities that improve disc failure quick recovery and fault tolerance.
