We havea
Quad-Intel XEON 2.0GHz (1MB cache), 12GB memory, running RH9, PG 7.4.0. There's
an internal U320, 10K RPM RAID-10 setup on 4 drives.
We are expecting

Other than the disks, I am curious what other people are using in terms
of the horsepower needed. The Quad server has been keeping up, but we
are expecting quite high loads in the near future, and I am not sure if
just by having the disks on a high-end storage will do it.
