Thank you much for the info.
I will take a look. I think the prices I have been seeing may exclude us
getting another 4 proc box this soon. My boss asked me to get something in
the 15K range (I spent 30 on the Dell). 
The HP seemed to run around 30 but it had a lot more drives then the dell
(speced it with 14 10k drives).

I can and will most likely build it myself to try getting a bit more bang
for the buck and it is a second server so if it dies it should not be a

FYI everyone using our system (after a week of dealing with many bugs) have
been saying how much they like the speed.
I did have to do a lot of creative ideas to get it working in a way that
appears faster to the client.
Stuff like the queries default to limit 50 and as they hit next I up the
limit (also a flag to just show all records and a count, it used to default
to that). The two worst queries (our case and audit applications) I created
denormalized files and maintain them through code. All reporting comes off
those and it is lightning fast.

I just want to say again thanks to everyone who has helped me in the past
few months.

Battery-backed avoids corruption if you have an unexpected power loss. 
It's considered mandatory with large-cache write-back controllers if you 
can't afford to lose any data.

Sounds like you need to try another vendor. Are you aiming for two RAID 
10 arrays or one RAID 10 and one RAID 5?

There's unlikely to be many common components between their workstation 
and server offerings. You would expect case, power, graphics, 
motherboard, storage controller and drives to all be different. But I'd 
challenge that 50% failure stat anyway. Which components exactly? Hard 
drives? Power supplies?

Almost anyone can build a workstation or tower server, and almost anyone 
else can service it for you. It gets trickier when you're talking 2U and 
especially 1U. But really, these too can be maintained by anyone 
competent. So I wonder about some people's obsession with 
vendor-provided service.

Realistically, most Opteron solutions will use a Tyan motherboard (no 
idea if this includes HP). For 4-way systems, there's currently only the 
S4882, which includes an LSI dual channel SCSI controller. Different 
vendors get to use different cases and cooling solutions and pick a 
different brand/model of hard drive, but that's about it.

Tyan now also sells complete servers - hardly a stretch seeing they 
already make the most important bit (after the CPU). Given the level of 
interest in this forum, here's their list of US resellers:

If it's a tower server, build it yourself or pay someone to do it. It 
really isn't challenging for anyone knowledgeable about hardware.
