You can use the GetStorageContainerEfficiency method to retrieve efficiency information about a virtual volume storage container.

Parameters

This method has the following input parameter:

Name Description Type Default value Required

storageContainerID

The ID of the storage container for which to retrieve efficiency information.

integer

None

Yes

Return values

This method has the following return values:

Name

Description

Type

compression

The amount of space saved by data compression for all virtual volumes in the storage container. 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 virtual volumes in the storage container. Stated as a ratio.

float

missingVolumes

The virtual volumes that could not be queried for efficiency data. Missing volumes can be caused by the Garbage Collection (GC) cycle being less than an hour old, temporary loss of network connectivity, or restarted services since the GC cycle.

integer array

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 GC.

ISO 8601 data string
