[Beowulf] Dual Processor & Dual IDE / SATA drives?

[Richard Fryer]

The several dual processor Opteron MB's I've looked at do seem to take
advantage of the dual memory channels.

We've wondered if dual hard drives (either SATA or IDE) are likely to
improve performance over single drives.

Has anyone attempted to isolate this issue in tests?  Is it related to dual
processor specific or would a single processor system have the same
(advantage / disadvantage) of two over one?

Thanks.
