Thin Provisioning Information

Item Description

Thin Provisioning

Whether the Thin Provisioning function is enabled or disabled is displayed.

Maximum Pool Capacity

The maximum pool capacity that is specified for the storage system is displayed.

The maximum pool capacity is the maximum total capacity for TPPs and FTRPs that can be created in the storage system. The chunk size for creating TPPs or FTRPs varies depending on the maximum pool capacity. Refer to "The Maximum Number of Pools, Maximum Pool Capacity, and Determined Chunk Size for Each Model" for details.

This item is displayed only when the Thin Provisioning function for the storage system is enabled.

Caution

  • The actual available capacity is limited if the maximum physical capacity of the drives that can be installed is smaller than the maximum pool capacity. For example, when using an ETERNUS DX8900 S4 that is configured only with 900 GB drives, the actual capacity that can be used is approximately 3.6 PB even if the maximum pool capacity is "8.00 PB".

Total Physical Capacity

The total physical capacity of the TPPs in the storage system is displayed.

This item is displayed only when the Thin Provisioning function for the storage system is enabled.
