|
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 Efficiency |
This field is blank if the calculation for items below is not complete. A hyphen (-) is displayed if the information is invalid. For details, see the Provisioning Guide.
NoteThe date and time in the square brackets are the system date and time (date, time, and timezone) of the storage system. For Last Updated in
Hitachi Device Manager - Storage Navigator, the date and time based on the system date and time (date, time, and timezone) of the SVP are displayed. Therefore, if the settings of the system date and time for the storage system and the ones for the SVP are different, the date and time in the square brackets in this window and the date and time displayed for Last Updated are also different. For details about system date and time settings for storage systems and SVPs, see the
Service Processor Technical Reference.

| Total Saving (Software Deduplication, Software Compression, FMD Compression) |
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. |

|
Item |
Description |
|
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 HDP 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. For a HDP 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 HDP Pool |
When the total is selected in Internal / External, this item displays the capacity remaining after subtracting the Used HDP Pool value from the total capacity of pool of Dynamic Provisioning. Control cylinder is not included in the capacity. The number of logical devices does not display. 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:
The control cylinder is not included in the capacity. The total capacity includes:
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 HDP Pool , Reserved - Unused HDP 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. |
