Basic SAS Cable
Each Phy is Full Duplex, cable length up to 8 metres @ 300 MB/s in each direction
A Narrow port contains a single physical interface which consists of a transmit
pair and a receive pair, operates at 300MB/s Full Duplex and has a cable
length of up to 8 metres.
Form factor compatible with SATA: allows for SATA drives to connect to a
SAS backplane, which obviates the need to install an additional SATA
controller just to attach a DVD-writer, for example.
Note that SAS drives are not usable on a SATA bus and have their physical
connector keyed to prevent any plugging into a SATA backplane.
