As a related side note: If the bandwidth you get is not what you
expect, it may well be that your switch is bad (or that your disks are
slow). That was my experience a couple of years ago, so we implemented
a switch benchmark called "Switchbench", that helps to identify the
bandwidth bottleneck in a network.
