Where did you find that the volume limitations went away in 7.3.1? I was under the impression that the limits stayed the same in 7.3, but simply doubled (ie 500G -> 1TB for 2020) in 7.3.1 .. anyone know which is true?

So far no confirmation from NetApp directly, we've all just "heard" things. I checked with my SE and he also had heard this but advised that they'd heard a lot of things that were supposedly to be included in 7.3.0 that weren't so to take it with a grain of salt.
Anyone from NetApp out there?? :)

I don't know if there is a limit to the number of ASIS volumes on a filer. I know there are limits to the number of active ASIS processes, but if you hit that, they just run in sequence like when the snapmirror/snapvault concurrent limits are hit.

I am evaluating the use of NFS datastore on NetApp for use with ESX. Initially the potential benefits of ASIS (dedup) had me just about sold, however, I discovered that with the FAS2020 we're looking at there is a 500GB limit to the size of ASIS enabled FlexVols. Bummer. I see this limit goes up to 1TB with the FAS2050, so I may need to compare that option as well... Mor! eover, I'm wondering what the limit on the *number* of max-sized AS IS enabled flexvols is per filer? Could I have 15 500GB ASIS enabled flexvols in the FAS2020 above? That wouldn't seem to make logical sense as I understand the limitation is tied to memory.... but this might help us get around this size limitation. Thanks in advance.

The last speculation I heard, which was pretty recently and a conservative one, was the A-SIS limits are still going to be in effect, but the limits are going to be raised and the amount is going to depend on the filer. I heard the smaller filers like the 2020, and possibly the 2050, will see a significant increase in A-SIS volume size of up to 100% and that the higher up the line you go the smaller that percentage of increase gets.
