Can anybody point me in the right direction in regards to optimizing
performance on an IBM FastT 200 SAN?

We have our SAN up and running, but the performance is pitiful. We
can only get 12MBps throughput. Definitely not what we envisioned.

I've tweaked the numerous settings recommended by IBM in all their
optimization manuals, but can't get any faster throughput. We are
ready to chuck all this expensive equipment.

Any help would be greatly appreciated.
