I just checked online and I think the MSA500 G2 has it's own SCSI RAID
controllers, so you are actually just using the 5i as a SCSI attach, which
it's not good at (no reordering/command queueing, etc). So, just using a
simple SCSI adapter to connect to the MSA might be a big win.

Yes, it has its own redundant controller,
