Topology and connectors

An initiator may connect directly to a target via one or more PHYs (such a connection is called a port whether it uses one or more PHYs, although the term wide port is sometimes used for a multi-PHY connection).

The SAS connector is much smaller than traditional parallel SCSI connectors, allowing for the small 2.5-inch (64 mm) drives. SAS currently supports point data transfer speeds up to 6 Gbit/s, but is expected to reach 12 Gbit/s by the year 2012.
