Efficiency info

Hi, is there a cmdlet that shows the total amount of space saved in a volume due to all efficiencies, including cross-volume dedupe?

You're likely looking for an attribute of the volumes.

PS C:\Users\Administrator.DEMO> $vols = Get-NcVol
PS C:\Users\Administrator.DEMO> $vols[-1].VolumeSisAttributes | fl


CompressionSpaceSaved                      : 0
DeduplicationSpaceSaved                    : 0
DeduplicationSpaceShared                   : 0
IsSisLoggingEnabled                        : True
IsSisStateEnabled                          : True
IsSisVolume                                : True
NcController                               : cluster1
PercentageCompressionSpaceSaved            : 0
PercentageDeduplicationSpaceSaved          : 0
PercentageTotalSpaceSaved                  : 0
TotalSpaceSaved                            : 0
CompressionSpaceSavedSpecified             : True
DeduplicationSpaceSavedSpecified           : True
IsSisLoggingEnabledSpecified               : True
IsSisStateEnabledSpecified                 : True
IsSisVolumeSpecified                       : True
PercentageCompressionSpaceSavedSpecified   : True
PercentageDeduplicationSpaceSavedSpecified : True
PercentageTotalSpaceSavedSpecified         : True
TotalSpaceSavedSpecified                   : True

Probably TotalSpaceSaved

@karmic estuary Thanks for the info ! I don't see compaction and cross-volume-dedupe on the list. Do you know if TotalSpaceSaved contains these as well ?

cross-volume-dedupe I would think this would be under the hosting aggregate's attributes.
Use $vols[-1] | Get-Member to discover the attributes in-terminal. Unfortunately I don't have the cycles at the moment.
fl is the alias for Format-List but I will say this sometimes reveals more attributes: $vol[-1] | select * | fl
