Re: HF20 de-dupe statistics
Hello!
Deduplication is performed at the Application Category level, and thus the dedupe results cannot be reported on a per-volume basis as there could be many blocks shared across many volumes that are part of the same Application Category.
If you head to Monitor->Capacity, you can see the dedupe/compression savings on the App Category level there. Alternatively, the overall Pool Capacity figures also include the global dedupe/compression savings.

Re: HF20 de-dupe statistics
And what exactly do "Application Category level" mean in this case?

Re: HF20 de-dupe statistics
That's ok! If they're CSV attached shared drives, then that's exactly how it should be.

Re: HF20 de-dupe statistics
I know. I ment, the application statistics is not worth much, as all is reported as the same application :)
