What model server are you using? I've got a p640 with 2 6228s and used a
script to test. With 3 instances of the script, I maxed out at approx.
100MB/s on that server. When I used 2 servers (1 instance on each), I was
able to get around 70-75MB/s per server. These tests were using multiple
LUNs on a Hitachi 9200...

Curious, how did you come up with these numbers? I can't think of any tools
that tell could tell you that, short of a third-party product.
