Hello,
Has anybody upgraded to 8.1.4 P9 7-Mode yet? I am looking to upgrade to 8.1.4 P9 from 8.1.4 P3 shortly.
I am especially curious if there are any known issues with 8.1.4 P9 because it is currently the latest release in the 8.1.4 family. If 8.1.4 P9 turns out to be problematic, we will be forced to upgrade to an 8.2.X release.
We've been hesitant to upgrade to an 8.2.X release because our average controller utilization is 40-45% (avg_processor_busy) and, as I understand it, we can expect a bump of 10-20% CPU utilization on account of new code/features that have been introduced in 8.2.x.
Thanks, Phil

Yep, last week, from 8.1.3.

Just works, but were using only NFS, CIFS, Snapmirror.

We don't graph CPU usage on these boxes, so I don't know.
We won't upgrade to 8.2 because it does not support flash cache (at least on FAS3210). But we will upgrade to some 25xx box with CDOT next month. (And our FAS6290 FMCs probably too.)
Grtnx,

What (which) FAS models is this..?
As you'd expect the 10-20% CPU util increase, well, it depends :-) On which protocols are in use and the workload parameters
Oh and: Happy new year, close now!

They are our old systems. Specifically, FAS3240's with 512GB Flash Cache. They service mostly NFS and Fibre Channel workloads. A fair amount of CIFS and very little iSCSI. All of them are running deduplication jobs against 15-20 volumes with a decent change rate. All the 3240's serve as both the source and destinations for snapmirror relationships.
We get pretty good use out of the 3240's but we'll be happy when it is time to replace them. In the meantime, it would be nice if we could get them to 8.2 like our newer 7-mode systems. Worst case scenario is we upgrade to 8.2 and performance is terrible due to the increased CPU utilization.
It is difficult to label the workloads they service. The heaviest hitters are Microsoft Exchange, SQL Server and vSphere. We host a range of virtual machines on this filer, including virtualized SQL servers. A diverse set of workloads is probably the best I can do to describe the workload.
Thank you much for the response! -Phil
