Eric, one final question:
http://www.lsi.jp/storage_home/products_home/host_bus_adapters/sas_hbas/lsisas3041er/index.html
This obviously has 4 SAS/SATA ports (regular cables) and looks like it 
would be great in Linux/SW raid for SAS/SATA disks.

This (8 port version):
http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/lsisas3081er/index.html
Has two SFF-8087 mini-SAS connectors.

It states "two (4) x1 SATA cables"

Does this mean:

8087 ------------> 8087 (with 4 lanes)

Thus it would require the purchase of an additional breakout cable or 
attachment to a special SATA/SAS enclosure.

or:

8087 ------------> regular sas/sata/1
                    regular sas/sata/2
                    regular sas/sata/3
                    regular sas/sata/4

Justin.
