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-2 (SPC-2).

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

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