What flash cache issue do you mean (it was apparently off-list reply)? Flash cache is not supported on FAS3210, but the problem appeared in Data ONTAP 8.1 already. FAS3240 should be OK, at least from formal support PoV.

Thanks for the info!
Peter - I did not know flash cache would potentially be an issue. We are using flash cache on our 3240 systems. Will definitely look into this further.
Mike - glad to hear it has worked out well for you with the 2240s! That makes me feel a little more optimistic about the possibility that we can upgrade our 2240s.

So far, no issues related to CPU, rather, the usual IOPS ceiling/need to add disks which comes with growth over time.

Just curious if anybody is running an ONTAP 8.2.x 7-mode release on a 2240, 3240 or comparable unit? If so, was there a noticeable increase in cpu utilization and/or client response time following the upgrade to 8.2.x?
We are currently evaluating an 8.2.3 7-mode upgrade from 8.1.3. On 8.1.3, we do see periods in which average processor utilization is in the 80-90% range. We're told we may want to avoid upgrading those units to an 8.2 release as 8.2 requires an additional 10-20% cpu out of the gate.
Thanks, Phil
