Serial ATA Ports
There are six Serial ATA Ports (I-
SATA0~I-SATA 5) located on the

ports and two SATA3 ports. These
ports provide serial-link signal con-
nections, which are faster than Paral-
lel ATA. See the table on the right for
pin defi nitions.
SAS Ports
Eight Serial Attached SCSI ports
(SAS 0~3, 4~7) provide serial link
connections. These ports are sup-
ported by an LSI 2208 ccontroller.
See the table on the right for pin
defi nitions.
