The answer to your question is yes.
I forgot my machine has 4 processors in it.
Your CPU utilization profile does not match mine so, I do not know if I can
help.
We have a P660-6H1 identically configured, except I use Shark Disk and
Magstar tape using FC and the Ethernet is Gigabit. The only time I see high
CPU utlization is during backups coming down the ethernet. At about
70MB/sec it pegs the system. A copy of a diskpool to tape or tape to tape
takes about 3% of the system. We currently have 12 FC drives on the systems
and have never seen it over 35% utlization during no backups coming in, but
CPU usage is linear on the arrival of IP packets.
Our disk pool is about 512GB we copy about 7TB a day, because we create an
onsite and offsite copy. We backup about 850GB a day from around 150
clients (AIX, NT, W2K, SGI, Solaris Clients). We have a lot of data that
will be moved to SAN tape soon that will relieve the Gigabit. We are adding
2 more FC cards (will be 6 then for tape coping).
Do not know what to say. I am getting about twice the amount through the
system with the same configuration except. GIGABIT and FC disk and tape.
