Term Description
Unused space Storage space that is physically currently available for the NAS volume. To calculate the amount
of available space for a NAS volume, use: (unused NAS volume reserved space) + (NAS volume
unreserved space
Overcommitted space Storage space allotted to a thin-provisioned volume over and above the actually available
physical capacity of the NAS pool. To calculate the amount of overcommitted space for a NAS
volume, use: (Total volume space) (NAS pool capacity)
With thin provisioning, storage space is consumed only when data is physically written to
the NAS volume, not when the NAS volume is initially allocated. More storage space can be
allocated to the NAS volumes than has been allocated in the NAS pool itself.
Snapshot space Storage space occupied by snapshots of a NAS volume
Data reduction saving Storage space reclaimed as a result of data reduction processing
Managing the Storage Profile for a NAS Cluster or Pool
Storage Center Storage Profiles control how Storage Center manages volume data. The selected Storage Profile dictates which
storage tier accepts initial writes, as well as how data progression moves pages between storage tiers to balance performance
and cost.
For more information about Storage Profiles, see the Storage Manager Administrators Guide.
