Key metric terms and descriptions for storage systems with HPE Storage OS prior to 3.3.1

  • Admin Free Space: Admin Rsvd Space that is not used. This is 0 (zero) for snapshots.

  • Admin Raw Rsvd Space: Raw physical drive space that is reserved for the admin space (snapshot metadata) in a virtual volume. This is 0 (zero) for snapshots.

  • Admin Rsvd Space: Space that is reserved for admin space in a virtual volume (Admin Used Space + Admin Free Space). This is 0 (zero) for snapshots.

  • Admin Used Space: Admin space (snapshot metadata) space that is used by virtual volumes. This is 0 (zero) for snapshots.

  • Admin Vcopy Space: Admin space that is used by snapshots only. This is 0 (zero) for all virtual volumes that are not snapshots. The value is calculated by running the HPE 3PAR CLI updatesnapspace command. HPE 3PAR System Reporter does not run this command. Beginning with HPE Storage OS 2.3.1, running the updatesnapspace command can be scheduled to run periodically.

  • Compaction Ratio: Ratio of the physical storage space that virtual volumes consume compared to their virtual size. The ratio applies to both thinly provisioned and thinly deduped virtual volumes.

  • Dedup Ratio: Ratio of the physical storage space that would have been used without deduplication, compared to the physical storage space used by thinly deduped virtual volumes. The dedup ratio does not include savings from inline zero detection.

  • Snap Free Space: Snap space that is not used. This is 0 (zero) for snapshots.

  • Snap Raw Rsvd Space: Raw physical drive space that is reserved for snap (copy) space in a virtual volume. This is 0 (zero) for snapshots.

  • Snap Rsvd Space: Space that is reserved for snap (copy) space in a virtual volume (Snap Used Space + Snap Free Space). This is 0 (zero) for snapshots.

  • Snap Used Space: Snap (copy) space that is used in a virtual volume. This is 0 (zero) for snapshots.

  • Snap Vcopy Space: Snap (copy) space that is used in snapshots only. This is 0 (zero) for virtual volumes that are not snapshots. The value is calculated by running the HPE 3PAR CLI updatesnapspace command. HPE 3PAR System Reporter does not run this command. Beginning with HPE Storage OS 2.3.1, running the updatesnapspace command can be scheduled to run periodically.

  • User Free Space: User space that is not used. This is 0 (zero) for snapshots.

  • User Raw Rsvd Space: Raw physical drive space that is reserved for user space in a virtual volume. This is 0 (zero) for snapshots.

  • User Used Space: User space that is used in a virtual volume. For fully provisioned virtual volumes, all User Rsvd Space is considered used. For thinly provisioned virtual volumes, only some portion of the User Rsvd Space can be used (the rest is User Free Space). This is 0 (zero) for snapshots.

  • User Rsvd Space: Space that is reserved for user space in a virtual volume. This is 0 (zero) for snapshots.

  • Total Raw Rsvd Space: Total raw physical drive space (User + Snap + Admin) that is reserved for a virtual volume. This is 0 (zero) for snapshots.

  • Total Rsvd Space: Total reserved space for a virtual volume (User Rsvd Space + Snap Rsvd Space + Admin Rsvd Space). This is 0 (zero) for snapshots.

  • Total Used Space: Total used space for a virtual volume (User Used Space + Snap Used Space + Admin Used Space). This is 0 (zero) for snapshots.

  • Total Vcopy Space: Total (Snap + Admin) Vcopy space used by snapshots only. This is 0 (zero) for all virtual volumes that are not snapshots. The value is calculated by running HPE 3PAR CLI updatesnapspace command. HPE 3PAR System Reporter does not run this command. Beginning with the HPE Storage OS 2.3.1, running the updatesnapspace command can be scheduled to run periodically.
