No, I mean, how many drives do you have, what kind of RAID controller,
if any, how they're configured, and so on.  :)  Sorry wasn't really
clear there was I?

The vmstat numbers are horrible by the way, assuming they're in 1k
blocks, you're reading and writing at < 1 Meg a second.  It almost
looks like a degraded RAID-5 array.
