Disk group capacity
The capacity-related terms for disk groups that are used by HP P6000 Command View depend
on the controller software version on the storage system. The terms are described below. Capacity
measures of MB, GB and TB are binary values. See Storage capacity FAQ.
HP XCS 10000000
HP P6000 Command View displays uses these capacity terms for disk groups:
• Total capacity. Shows the formatted physical disk drive capacity of the disk group.
• Allocated capacity. Shows the amount of disk group capacity that is being used for virtual
disks.
• Available capacity (estimated). Shows the capacity remaining in a disk group if all new virtual
disks were to be created as either Vraid0, Vraid1, Vraid5, or Vraid6 (see Vraid overview).
◦ Physical. This value is estimated from various factors such as the number and size of
virtual disks that might typically be created. The actual available physical capacity may
be more or less than the estimate.
◦ Thin provisioning. This value is based on the maximum addressable storage space of the
storage system.
• Requested capacity. Shows the amount of space in disk group that has been requested for
virtual disks.
• Oversubscribed capacity. Shows the amount of space requested via thin provisioning that
exceeds the physical capacity that can be allocated.
HP XCS 9.5x
HP P6000 Command View displays uses these capacity terms for disk groups:
• Total capacity. Shows the formatted physical disk drive capacity of the disk group.
• Allocated capacity. Shows the amount of disk group capacity that is being used for virtual
disks.
• Available (estimated). Shows the unallocated capacity remaining in a disk group if all new
virtual disks were to be created as either Vraid0, Vraid1, Vraid5, or Vraid6 (see Vraid
overview). This value is estimated from various factors such as the number and size of virtual
disks that might typically be created. The actual available capacity may be more or less than
the estimate.
• Requested. Shows the amount of space in disk group that has been requested for virtual disks.
