For the Serial Attached SCSI, the ANSI standard defines Point-to-Point technology. Figure 1.1 and Figure 1.2 give examples of the SAS system configuration.

(1)Port addressing

Every device connected with the SAS protocol has a unique address (SAS address). SAS addresses are in the Name Address Authority (NAA) IEEE Registered format defined by SCSI Primary Command-3 (SPC-3).

An SAS address consists of 8 bytes as a unique value set for each device.

The initiator can implement an I/O operation on a disk drive by using the corresponding SAS address stored by the HDDs.
