You can use the GetVolumeAccessGroupEfficiency method to get efficiency information about a volume access group. Only the volume access group you provide as the parameter in this API method is used to compute the capacity.

Parameter

This method has the following input parameter:

Name Description Type Default value Required

volumeAccessGroupID

Specifies the volume access group for which capacity is computed.

integer

None

Yes

Return value

This method has the following return value:

Name

Description

Type

compression

The amount of space saved by data compression for all volumes in the volume access group. Stated as a ratio where a value of 1 means data has been stored with no compression.

float

deduplication

The amount of space saved by not duplicating data for all volumes in the volume access group. Stated as a ratio.

float

thinProvisioning

The ratio of space used to the amount of space allocated for storing data. Stated as a ratio.

float

timestamp

The last time efficiency data was collected after garbage collection.

ISO 8601 data string

missingVolumes

The volumes that could not be queried for efficiency data. Missing volumes can be caused by a recent garbage collection, temporary network loss or restarted services since the garbage collection cycle.

integer array
