Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target with 2 LUNs within the same SSP
Target Port. If the DUT is an initiator, it will need to have software capable of generating SCSI traffic.
Revision History: September 23, 2004
Test Setup: The DUT and the Testing Station are physically connected. The SAS Initiator DUT is attached to the
SAS Target through a SAS Protocol analyzer.
Test Procedure (SSP Initiators):
• Allow the DUT to open a connection to the attached SAS Target. Observe commands from the DUT to
each LUN on the target.
Observable Results: If the DUT is an initiator, verify that the TAG field is unique for commands to different LUNs
no the SSP target port.
