Re: dell versus hp

Apart from the disks, you might also investigate using Opterons instead
of Xeons. there appears to be some significant dent in performance
between Opteron and Xeon. Xeons appear to spend more time in passing
around ownership of memory cache lines in case of a spinlock.
It's not yet clear whether or not here has been worked around the issue.
You should at least investigate it a bit.

We're using a HP DL385 ourselves which performs quite well.
