I'd be taking a serious look at the Sun x2100's discussed on this list
recently.  Bang for the buck looks awesome.  It's a sIngle Opteron 100
based system.  Then if you need more disk I/O and db heavy lifting add
a 2nd db machine.  You still get a Tyan based system but form a company
w/enough clout to kick Tyan in the butt andget them moving if a hw bug
is uncovered. 

fwiw- I don't like Maxtor HD's.  Yeah, I know SR raves about the
performance but I still don't see them as enterprise class storage
unless the emphasis is on cheap and mass.  Do you really need 12x300GB
of storage? If not and you're hooked on SATA why not consider the WD
Raptor/  Personally I'm still a SCSI guy when it comes to anything
that's going to be doing any disk I/ O though so take my $0.02 w/a
grain of salt.

Q: Because it reverses the logical flow of conversation.
A: Why is putting a reply at the top of the message frowned upon?
