Allocation summary

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 Hitachi 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.

For Last Updated in HDvM - SN, 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.
