> I am currently doing some benchmark on OpenIndiana ZFS for my SAN environment where I will run VMs and I wonder if dedup could have impact on performance. I want to set it off (as it on by default) so I use "zfs set dedup=off poolname. I'm not sure it was really disabled. How can I check this?

Deduplication is disabled by default, I wonder why you think otherwise?

You can get the deduplication setting for all datasets by running:
zfs get dedup
