Supermicro also lists this: http://www.supermicro.com/products/accessories/addon/AOC-USAS-L8i.cfm http://www.lsi.com/storage_home/products_home/standard_product_ics/sas_ics/lsisas1068e/index.html Not much onboard ram, but it's PCI-E and even SAS. CDW lists it for $155. That would be cheaper than buying a new board with a PCI-X slot or two, and would even handle SAS drives. Claims to be based on the "LSISAS 1068E SAS controller". Any idea if that is supported? I don't see it listed in the mfi man page. LSI has a Linux driver for download. That card looks like it would be just what I need.
