We're using fas3050's as "flex caches". The busiest ones have 60 + flex vols on them in a 600G aggregate. Pay close attention to the NetAPp best practices for Flex Vols, and have a good understanding of your environment, the expected traffic thru each volume, etc, to set the sizes and reserve as appropriate in your environment.
Each flexcache volume has some memory and disk overhead, just to exist. As long as your total active working set doesn't exceed the aggregate size, sizing should be OK. Note to that flex cache volumes impose a load on the origin filer, too, so you'll want to monitor that as well.

We are ready to roll out flex-vols and are discussing about the possible performance impact of having lot of flex-vols on a aggregate. We are talking about having 20-30 flex-vols per aggregate.
