Ohh..those shelves. I -think- theyre FC7s and FC8s. Should work with
any head thru the 800 series of filers, I dont recall the official
answer on using those with 900s.
I get fuzzy with what I know works, and whats supported works.

Subject: F720 head upgrade?
My good old F720 seems to have run out of gas. It is now running at
100% CPU utilization all the time and application performance has gotten
really bad.
I'm hoping to be able to upgrade the head and still use the three drive
shelves. But I'm wondering why I'm seeing this poor performance all of
a sudden and if it really is normal behavior.
The F720 has a gigabit network interface but network usage never goes
over 10%. When network usage gets to 5%, which would mean 50 Mbps, the
CPU hits 100% and stays there.
Is that really the maximum capacity of an F720?
The three drive shelves are:
Shelf 0: EDM Kernel Version : 0.4 App. Version : 0.0
Shelf 1: VEM Kernel Version : 2.5 App. Version : 3.1
Shelf 2: VEM Kernel Version : 2.5 App. Version : 3.1
What options do I have for replacing the head with a faster one that
would work with these shelves?
