No, our TSM server is one of the few servers we run that has its own iron.
It's a dual 2GHz Xeon, 2.5G RAM, RHEL 3.0, DB on local 15k RPM RAID 1, disk
pools on SAN (RAID 5 array, 10k RPM).

That's very good performance, out of curiosity,
is your TSM server also running on top of VM ?
I know VM instances can talk to each other over the memory instead of
over the net
