STORED This field contains the percentage of the defined functional capacity that contains stored data (occupying disk array storage) for the device or subsystem.

UNUSED This field contains the percentage of the defined functional capacity for the device or subsystem that does not yet contain data and is thus unused (that is, not occupying disk array storage).

PHYS. USED(MB) This heading covers the field containing the real capacity in megabytes, that occupies disk array storage, as opposed to the functional capacity. The difference between the stored and the physical used capacity is the savings due to compression and compaction performed by the RVA subsystem for this device.

COMP. RATIO This heading covers the field containing the real compaction ratio, which is the quotient of functional capacity stored/physical used capacity.
