Nancy,

We are just beginning to think about replacing the older of our two TSM
servers.  I am thinking that a p6 570 may be overkill, but we are looking
at a p6 550 as it has a bit more head room than the 520 (in case we need it).

I'm sorry--I forgot to add some additional information.  Our p-570 has
four 1.9GHz CPU's (Power 5+) vs. two 4.2 GHz CPU's (Power 6) for the
p-520.
