Call IBM Global Services, and tell them you are interested in purchasing
an RS/6000 with a 7133 SSA drives, one tray off-site using the fiber
extenders.

With those, you can have your drives up to 2.4 km from the server they're
connected to, while they still are local to the machine. (And you still
get 4 simultaneous reads/writes in each direction of the loop, for a total
of 160 Mbyte/sec transfer.)
