Spanning of multiple disks
|
Eliminates media size limitations. |
Striping
|
Increases
throughput and bandwidth. |
Mirroring or RAID-5
|
Increases data availability. |
Online relayout
|
Allows volume layout changes without application or database downtime. Online relayout can be used to change performance or reliability characteristics of underlying storage. |
Volume resynchronization
|
Ensures that all mirrors contain exactly the same
data and that the data and parity in RAID-5 volumes agree. |
Dirty Region Logging (DRL)
|
Speeds the recovery of mirrored volumes after a system
crash. |
Volume snapshots
|
Allows backup of volumes based on disk mirroring.
VxVM provides full-sized and space-optimized instant snapshots,
which are online and off-host point-in-time copy solutions.

Hot-relocation
|
Automatically restores data redundancy in mirrored and RAID-5
volumes when a disk fails. |
Dynamic multipathing (DMP)
|
Allows for transparent failover, load sharing, and
hot plugging of physical disks. |
Volume sets
|
Allows
several volumes to be represented by a single logical mount device. |
Dynamic LUN Expansion
|
Allows you to resize a disk after it has been initialized
while preserving the existing data on the disk. |
Storage Expert
|
Helps diagnose configuration problems with VxVM. |
Cluster Volume Manager (CVM)
