Hi Pete,

I agree with Tom -- this looks like a great configuration. I always spec as
much memory as I can afford without breaking the bank. It looks like you
did the same...

We've avoided SAS in favor of more stripes on more SATA drives -- so far,
it's worked out reasonably well (knock on wood).

That looks like a reasonable config. I'd probably go with straight SATA,
especially using enterprise drives with a spare or two.

I've not mixed SAS and SATA on the same controller though I have heard it done.
Let me know if I can offer any help -- it looks like you have great specs...
