I know that if a Filer is not busy serving data it will run background task at a higher priority that will use the spare CPU while the Filer is not under load.
In an active/active config the Filer CPU shouldn't be over 50% on each controller as above this the Filer is not longer HA.
My question is if a Filer is showing low latency and isn't busy but its CPU is at 50% on each controller is this an issue?
I'm not clear if you have two controllers showing 40/50% CPU due to background tasks that isn't busy whether it will still be HA if one controller were to fail? My thinking is those background tasks will just run at a lower level (some may not run in failover state??)
