[LON-CAPA-admin] Server Suggestions

Just putting this out there for some quick systems advice.

We've been running 3 Dell Poweredge 2650's - Dual 2GHz Xeons, 2MB RAM, 
dual power supply.
One has a 3 disk RAID array and a tape backup. We have one spare that I 
recently pressed into service. All 4 chasses(spelling of plural?) are 
interchangeable, so if one dies (particularly the library server), I just 
switch out the disks and keep going.

They are now 3.5 years old, I'm seeing a few flaky SCSI issues on the 
library servers (SCSI has gone offline a couple times in last 6 months, 
which creates a mild panic). They are off warranty/service.

I'm getting ready to put in for funds for a replacement library server. 
The idea would be to get two identical machines, so that if one dies I can 
switch over to the other quickly. I'd then keep the 2650's going until 
they drop.

Does anyone have suggestions? One obvious option is pick up two 2850s. How 
much of an advantage is a 6850? Are there suggestions of nice AMD systems 
that people have been happy with? I'm looking for rackmount.
