We've not upgraded for ages, and we must do so.  But this should set an
interesting lower floor on the amount of hardware you need.

Sun Ultra 2, Solaris 7, 2x167MHz processors, 1.5GBytes RAM, two
Fast/Wide SCSI controllers, 200GBytes of usable disk built from a mess
of RAID 0+1 resulting from filesystem growth over the years:

As of this minute 473 (load average 0.16, 0.25, 0.26), average about 400
during the day.  Load average never seen to go even close to 1.
