Volume
A Volume is a fixed amount of storage. One Volume can span over more than one
physical hard disk drive. It all depends on how you set up your Volumes. The controller
treats one or more hard disk drives or unused space on a hard disk drive as a single array.
A Volume provides the ability to concatenate storage from various hard disk drives
regardless of the size of the space on those hard disk drives. A Volume is useful in
scavenging space on hard disk drives unused by other arrays. A Volume does not provide
any performance or data redundancy benefit.
WAN

WDS
