disk array.

Volumes and their

This represents the internal (physical) hard drives.

Used Space

This represents how much of a volume’s capacity is currently filled by 
files.

Locked Volume

Used Space (snapshot)

Snapshots (records of changes to files within a volume) are stored in the

how much of that space is currently filled by snapshots. See 

 for more on snapshots.

This is space on the disk array that is not allocated to volumes and is not 
(yet) used by snapshots.
