It was our hope that asis would be run on the aggregate level and that would get rid of volume limits altogether. I believe in 7.3, the metadata was moved to the aggregate and that was the first step needed.
It seems to be taking longer than expected for 7.3.1 to get released, lets up its soon.

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.

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?? :)

might help us get around this size limitation. Thanks in advance. (No sales replies to this please) Ray
I believe that is still NetApp's hope as well, but I'm sure there are still plenty of hurdles that need to be cleared before we'll see it come to fruition. The one thing that would need to be taken into account is some sort of an exclusion property, as in I want deduplication to run across everything except for these two volumes. Deduplication is fantastic, but there are still places where it wouldn't be recommended to run it for performance and efficiency reasons.

Hearing that the meta data is moving to the aggregate level worries me, how will this effect aggregates that have say 10 volumes each with 20 million files in them ?
