Viewing Information About SmartDedupe and SmartCompression

Context

This section describes how to view the related parameters of a single LUN after SmartDedupe and SmartCompression are enabled. To view the capacity saved by SmartDedupe, capacity saved by SmartCompression, and capacity saved by SmartDedupe and SmartCompression of all LUNs in a storage pool, see the section about viewing storage pool information in the basic storage service configuration guide for block specific to your product model and version.

      Table 3-1 Related parameters of SmartDedupe and SmartCompression

      Parameter	Description	Value
      Total Space before Saving	Storage space occupied by data before SmartDedupe and SmartCompression are enabled	[Example] 1000.000 MB
      Total Space Saved	Storage space saved after SmartDedupe and SmartCompression are enabled	[Example] 20.000 MB (2%)
      Enable deduplication	The deduplication function is enabled. After SmartDedupe is enabled, the check box is selected.	[Example] Enabling data deduplication (SmartDedupe)
      Saved Space after Deduplication	Size of storage space (storage pool capacity) saved by the deduplication of data written to LUNs. The unit is MB (%). MB: indicates the saved storage space. %: indicates the percentage of the size of deduplicated data in the total size of data written to the LUNs. NOTE: When SmartDedupe is not enabled or the system has not performed data deduplication, the value of the parameter is 0.000 MB (0%).	[Example] 10.000 MB (1%)
      Enable data compression	The compression function is enabled. After SmartCompression is enabled, the check box is selected.	[Example] Enabling data compression (SmartCompression)
      Saved Space after Compression	Size of storage space (storage pool capacity) saved by the compression of data written to LUNs. The unit is MB (%). MB: indicates the saved storage space. %: indicates the percentage of the size of compressed data in the total size of data written to the LUNs. NOTE: When SmartCompression is not enabled or the system has not performed data compression, the value of the parameter is 0.000 MB (0%).	[Example] 10.000 MB (1%)
