A Vdisk is a set of one or more physical disk drives forming a RAID group that serve as
backup storage for one or more volumes.
Vdisk
A volume can be viewed as a logical partition of a Vdisk. The RAID level of the volume
is the RAID level of the Vdisk.
Volume
A spare is a disk drive that has been assigned to provide fail-over storage for a failed
drive in a Vdisk. The controller automatically reconstructs a redundant (fault-tolerant)
Spare
Vdisk when one or more of its disks fail and a compatible spare disk is available. A
compatible disk has enough capacity to replace the failed disk and is the same type
(SAS or SATA). The SPT tool supports addition and deletion of global-spares. A
global-spare is reserved for use by any redundant Vdisk to replace a failed disk.
