Quick reference, you get one of these:
http://www.aberdeeninc.com/abcatg/Stirling-X888.htm
with dual 2.26GHz Nehalem CPUs, 48 Gigs ram, and 48 73K 15kRPM Seagate
barracudas for around $20,000. That's the same cost for a single
oracle license for one CPU. That's way overkill for what you're
talking about doing. A machine with 8 or 16 disks could easily handle
the load you're talking about.
