Allocation summary

The following table describes the fields and settings in the allocation summary section of the Storage Systems window.

Item	Description
Internal / External	This item switches the displayed items. Total: Displays information on both the internal volumes and the external volumes. Internal Only: Displays information on only the internal volumes. External Only: Displays information on only the external volumes.
Capacity Unit	This item switches the displayed units of the capacity. Appropriate: Displays the capacity in appropriate unit depending on the capacity of each item. TB/GB/MB: Displays the capacity of the specified unit.
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. Total Efficiency: Displays the ratio of the total saving effect achieved by accelerated compression, capacity saving (compression and deduplication), snapshot, and Dynamic Provisioning. The ratio of the system data is not included. Data Reduction: Displays the data reduction ratio before and after performing the accelerated compression function and the capacity saving function (compression and deduplication). The ratio of the system data is not included Software Saving: Displays the capacity reduction ratio for data which is before and after performing the capacity saving function. The ratio of the system data is not included. Compression: Displays the capacity compression ratio for data which is before and after performing the capacity saving function. Deduplication: Displays the capacity deduplication ratio for data which is before and after performing the capacity saving function. Pattern Matching: Displays the capacity reduction ratio for data before and after performing pattern matching of the capacity saving function. FMD Saving: Displays the capacity reduction ratio for data which is before and after performing the accelerated compression function. The ratio of the system data is not included. Compression: Displays the capacity compression ratio for data which is before and after performing the accelerated compression function. Pattern Matching: Displays the capacity reduction ratio for data before and after performing pattern matching of the accelerated compression function. Snapshot: Displays the efficiency ratio achieved by snapshot. The ratio of the system data is not included. Provisioning: Displays the efficiency ratio achieved by Dynamic Provisioning. The ratio of the system data is not included. Date and time for calculation: The start date and time and the end date and time for the calculation are displayed within the square brackets. 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 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.
Total Number of LDEVs	The number of LDEVs. The information displayed in this field depends on the type of system. See the following table.

Physical summary

The following table describes the fields and settings in the physical summary section of the Storage Systems window.

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 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. 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. 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: Thin Image pool volumes Quorum disk 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) Volumes that belong to a parity group for which accelerated compression is enabled, but are not registered in a 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.

Virtual summary

The following table describes the fields and settings in the virtual summary section of the Storage Systems window.
