General Description

1.3System Configuration

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.

Figure 1.1 Example of SAS system configuration (Dual port internal cabled environment)

Figure 1.2 Example of SAS system configuration (Dual port internal backplane environment)

(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.
