I agree that a basic RAID may be desirable. We have a series of dual
Xeon 2.4GHz with 1-2Gig RAM processing maybe 1/2 million pieces of email
a day. These machines in particular do spamassassin and run in parallel
(6 machines behind a load balancer). During mail bombs the machines show
signs of sweating under the perl load and there is the recurring issus
of either softupdates causing backtraces or some other memory paging
event causing them - again only under the severest of loads. We do not
use a RAID solution on those so using a simple strip may help avoid the
situation we are seeing (5.2.1-Release-P8). We also use FreeBSD on our
primary MX machines (again a load-balanced series of 3 machines) and
these are not running any perl processes - simply sendmail with
extensive access lists. These machines run flawlessly and combined
handle some 2 million+ emails a day.
