I picked up the machines on Saturday. The E5500 didn't have any disk bays
in it and I really don't have room for another refrigerator so I stripped
it for parts. I kept everything except for the cabinet sheet metal.

The E3500 doesn't have any disks in it either so it looks like I get to
learn about FC-AL. I removed one of the Sbus I/O boards from the E3500 and
installed two of the CPU boards from the E5500. It now has 8x336 MHz CPUs
and 8GB RAM. The Sbus I/O boards all have Emulex LP9002S 2Gb/s FC boards on
them. I don't have anything to connect them to though. I do have an old Sun
RAID with a FC (25MHz?) interface that contains 30x2GB disks. Will this
connect to the FC ports on the 3500?
