Physical Summary

This item displays the capacity of physical logical devices and the number of devices. For details about this item, see the Physical Summary table.

Virtual Summary

This item displays capacity of virtual logical devices and the number of devices. For details about this item, see the table below about virtual summary.

Total Saving: Displays the ratio and capacity reduced by the capacity saving function against all data in a storage system.

When you use the capacity saving function, the saving ratio is calculated against metadata, garbage data, and parity data generated by the storage system in addition to user data. If the amount of used data volume before the capacity saving function is executed is smaller than the used pool capacity, a value which is invalid and smaller than the actually saved capacity might be displayed as the saved capacity.

Software Deduplication: Displays the ratio reduced by the deduplication function against all data in a storage system.

Software Compression: Displays the ratio reduced by the software compression function against all data in a storage system.

FMD Compression: Displays the ratio reduced by the FMD compression function against all data in a storage system.

Total DP Subscription Rate

This item displays the ratio of virtual logical device capacity to physical logical device capacity in the pool volume of Dynamic Provisioning.

For a Dynamic Provisioning pool in which Thin Image pairs are created, the virtual logical device capacity includes the snapshot data capacity.

Total Number of LDEVs

The number of LDEVs. The information displayed in this field depends on the type of system. See the following table.

Allocated

This item displays the capacity of path-defined volumes and the number of logical devices that the host can recognize. This capacity does not include the control cylinder.

Reserved - Used DP Pool

When Total is selected in Internal / External, this item displays the total capacity of the pages that are actually used in pool* of Dynamic Provisioning and the number of logical devices. The total capacity does not include the control cylinder. The pool volumes of Thin Image are not included in the Dynamic Provisioning pool volumes.For Virtual Storage Platform G200, Virtual Storage Platform G400, Virtual Storage Platform G600, Virtual Storage Platform G800, Virtual Storage Platform F400, Virtual Storage Platform F600, Virtual Storage Platform F800, the pool volumes of Thin Image are not included in the Dynamic Provisioning pool volume.

For a DP pool in which Thin Image pairs are created, the total page capacity includes the snapshot data capacity.

When an item other than Total is selected in Internal / External, this item displays the number of logical devices that are actually used in the Dynamic Provisioning pool*. The capacity does not display in this item, but is counted as part of Reserved - Other.

Reserved - Unused DP Pool

When the total is selected in Internal / External, this item displays the capacity remaining after subtracting the Used DP Pool value from the total capacity of pool* of Dynamic Provisioning. Pool volume of Thin Image is not included in pool volume of Dynamic Provisioning. Control cylinder is not included in the capacity. The number of logical devices does not display. For Virtual Storage Platform G200, Virtual Storage Platform G400, Virtual Storage Platform G600, Virtual Storage Platform G800, Virtual Storage Platform F400, Virtual Storage Platform F600, Virtual Storage Platform F800, the pool volumes of Thin Image are not included in the Dynamic Provisioning pool volume.

When an item other than Total is selected in Internal / External, the capacity and the number of logical devices are not displayed in this item, and the capacity is counted as part of Reserved - Other.

Reserved - Other

This item displays the total capacity and the number of logical devices of the following volumes:

• Journal volumes
• Thin Image pool volumes

The control cylinder is not included in the capacity.

The total capacity includes:

• The pool-VOL capacity that is not used as pool capacity
• The capacity of the system pool-VOL management area (approx. 4.1 GB per pool)

When an item other than Total is selected in Internal / External, the capacities for Reserved - Used HDP Pool and Reserved - Unused HDP Pool are also counted as part of this item.

Available Space - Unallocated

Displays volume capacity and number of logical devices which path is not allocated. The volumes of Reserved - Used DP Pool , Reserved - Unused DP Pool, and Reserved - Other are not included.

Available Space - Free Space

Displays the free space in which users can create volumes. The number of logical devices is not displayed for this item.

Physical Total

This item displays the total capacity of physical logical devices and the number of logical devices. Control cylinder is not included in the capacity.

DP Allocated ^*
