Working with a small FAS2750, 2 x ~10tb Aggregates. The only intention for this system is to use for VMware datastores via iscsi.
It seems thin volumes, and unreserved space luns are the general recommendation for this setup. What isn't clear to me is how to take advantage of the space savings from dedupe. As far as I can tell the only way to access this saved space would be to over provision luns from a volume which just feels kind of strange. I'd basically be taking a guess at what savings I might get and would need to watch space fairly closely.
Looking for suggestions or just confirmation that basically over provisioning luns is the only way to use the space savings in this scenario.
