Volume type

DP-VOL (V-VOL)

The LDEV number is handled in the same way as for normal volumes.

Maximum number of DP-VOLs

For VSP Fx00 models, only SSD can be specified.

For VSP G800 or VSP F800:

• Up to 14,080 per pool (For a pool with data direct mapping enabled, up to 1,023 per pool). Any number of available DP-VOLs can be associated with a pool.
• For a pool with Deduplication enabled, the maximum number of DP-VOLs with Compression or Deduplication and Compression enabled is 14,080.
• For a pool with Deduplication disabled, the maximum number of DP-VOLs with Compression enabled is 14,080.
• Up to 14,080 volumes per system. If external volumes and V-VOLs are used, the total number of external volumes and V-VOLs must be 14,080 or fewer.

For VSP G400, G600 and VSP F400, F600:

• Up to 4,095 per pool (For a pool with data direct mapping enabled, up to 1,023 per pool). Any number of available DP-VOLs can be associated with a pool.
• For a pool with Deduplication enabled, the maximum number of DP-VOLs with Compression or Deduplication and Compression enabled is 3,960.
• For a pool with Deduplication disabled, the maximum number of DP-VOLs with Compression enabled is 3,967.
• Up to 4,095 volumes per system. If external volumes and V-VOLs are used, the total number of external volumes and V-VOLs must be 4,095 or fewer.

For VSP G200:

• Up to 2,047 per pool (For a pool with data direct mapping enabled, up to 1,023 per pool). Any number of available DP-VOLs can be associated with a pool.
• For a pool with Deduplication enabled, the maximum number of DP-VOLs with Compression or Deduplication and Compression enabled is 1,912.
• For a pool with Deduplication disabled, the maximum number of DP-VOLs with Compression enabled is 1,919.
• Up to 2,047 volumes per system. If external volumes and V-VOLs are used, the total number of external volumes and V-VOLs must be 2,047 or fewer.

Volume capacity

Volume capacity from 46.87 MB to 256 TB per volume.

• TB: 0.01 to 256
• GB: 0.04 to 262,144
• MB: 46.87 to 268,435,456
• Blocks: 96,000 to 549,755,813,888

Total maximum volume capacity is as follows:

• VSP G800 or VSP F800: 6.5 PB (the shared memory must be installed)
• VSP G400, G600 or VSP F400, F600: 6.5 PB (the shared memory must be installed)
• VSP G200: 3.5 PB (the shared memory must be installed)

Path definition

Available.

LDEV format

Available. Quick Format is not available.

System option mode (SOM) 867 ON: When you format an LDEV on a DP-VOL, the capacity mapped to the DP-VOL is released to the pool as free space.

When you format a DP-VOL, the storage system releases the allocated page area in the DP-VOL. The quick format operation cannot be performed. If the LDEV format is applied to V-VOLs that are enabled for full allocation, the used capacity of the pool is not changed before the LDEV format is applied.

Caution:

• For a DP-VOL with deduplication and compression enabled, a deduplication system data volume whose LDEV status is Blocked cannot be formatted.
• For a DP-VOL with deduplication and compression enabled, a deduplication system data volume whose capacity saving status is Failed cannot be formatted.
