FAS2554 upgrade to ONTAP 9.1 - Is recommended?

alessice

Hi,

my FAS2554 (20x4TB+4x400SSD) is running 8.3.2P12 and works fine (I'm using only NFS as protocol).

Now I would like upgrade to 9.1P19 as suggested by Upgrade Advisor because for 8.3 NetApp don't provide anymore support.

Since FAS2554 was born with 8.3 so, is safe and recommended upgrade to 9.1?

Should I expect a drop in performance?

Thanks

We have FAS25xx series controllers running 9.5P4 with no issue, and upgrades have made them faster, not slower (when using the same features/workloads).

I'd go as high as possible. There are a few things that will make 9.3+ better. Ideally if you can go to 9.5Platest that would be the best.

Thanks Paul,

I will follow the upgrade path provided from Upgrade Advisor, so 8.3 -> 9.1, 9.1 -> 9.x and so on.

But ONTAP 9.5 can works fine with FAS2554 that have less RAM than 2750 (36GB vs 64GB)?

Yes. I've seen several filers on 9.5 on 2500s.

Hi,

I have done the upgrade via CLI and all works fine.

Only one thing need to fix, about every 5 minutes in the Events Log I found this debug messages:

acp.command.connect: Could not establish connection with 192.168.2.145.

and from console:
