Hi Chris,
Following are the details on each field.
Space Saving:Actual space saved due to dedupe. Displays the savings achieved through deduplication.
Physical Used:Displays the active file system data of all the deduplication-enabled volumes in the aggregate.
Effective Used:Displays the active file system data of all the deduplicated volumes in the aggregate without deduplication space savings.
Total Deduped Space: Is not documented at all.
looking at the example this is what I assume.
Total Deduped Space:Sum of the total capacity of all aggr where there is atlest one volume with dedupe enabled.
