Add 2x 146GB disks in RAID1 for OS and swap. In anything with intensive I/O it really helps. Go SAS for both OS disks and data if you can. I've found SAS seriously out performs SATAII for multiple mixed simultaneous read/write operations. SATAII, although MTBF is much better than it used to be still has problems with multiple simultaneous I/O requests and will become a serious bottleneck. We use 3 routing nodes running amavisd-new writing to a single database on a host which houses multiple databases. We use mailzu to view the quarantine and release messages plus an inhouse app to manage the sql tables for policies. The database host is a Dell PE1950, 4G RAM, with LSI MegaRAID (which is our bottleneck on I/O, PERC controllers are slow) and 2 RAID1 giving seperate spindles for OS and data. We don't have near the mail you handle (only around 20k/day) but the DB host does around 30 queries/second average.
