I found the manual for the 4 port U320 SCSI controller, and it listed
256 Meg for single data rate DIMM, and 512 Meg for DDR DIMM. This was
on the lsi at:

I believe.

They've got a new one coming out, that's SAS, like SCSI on SATA or
something. It comes with 256Meg, removeable, but doesn't yet say what
the max size it. I'd love to have one of these that could hold a couple
of gigs for a TPC type test.
