(VMware integration specific term) The client that Data Protector
uses to communicate with VMware Virtual Infrastructure. This
can be a VirtualCenter Server system (VirtualCenter environment)
or an ESX Server system (standalone ESX Server environment).
(ADIC and STK specific term) A VOLume SERial number is a
label on the medium to identify the physical tape used in very
large libraries. A volser is a naming convention specific to
ADIC/GRAU and StorageTek devices.
A unit of data storage in an LVM system. A volume group can
consist of one or more physical volumes. There can be more
than one volume group on the system.
(Windows specific term) An empty directory on a volume that
can be used to mount another volume. The volume mount point
acts as a gateway to the target volume. Provided that the volume
is mounted, users and applications can refer to the data on the
mounted volume by the full (merged) filesystem path as if both
volumes are one integral part.

(HP StorageWorks Disk Array XP VSS provider specific term)
One of two XP VSS hardware provider operation modes. When
the XP provider is in the VSS compliant mode, the source volume
(P-VOL) and its replica (S-VOL) are in simplex, unpaired state
after a backup. Therefore the number of replicas (S-VOLs per a
P-VOL) rotated is not limited. Restore from a backup in such a
configuration is possible only by switching of the disks.
