Bill,

Thanks for info.  Just curious, are you utilizing source-side dedupe or
relying on the TSM identify to identify all your duplicates
(post-process)? How does the maxsize parameter interact with source-side
dedup?  I'll have to look that up.

Eventually you have to reclaim your copy pools and based on your
hierarchies, it looks like reclamation would be feeding off from the large
4TB drives.  Have you had issues reclaiming from those pools?

Thanks!
Sergio
