Resource Requirements: SAS Protocol Analyzer and Generator

Test Setup: The DUT and the Testing Station are physically connected.
Test Procedure (SSP Target):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is a target the Testing Station should transmit an Identify Address frame
indicating that it is an Edge Expander.
• The Testing Station should open an SSP connection to the DUT from another address, imitating a SAS
Initiator.
• Wait for the DUT to transmit OPEN_ACCEPT and RRDY. The Testing Station should transmit a
SCSI INQUIRY command to the DUT, then close the connection.
• Wait for the DUT to open an SSP connection to the Testing Station to the same address that sourced
the SCSI INQUIRY command.
• The Testing Station should wait for the DUT to transmit an OpenAddress frame for an SSP
connection. The Testing Station should not respond to the OpenAddress frame with OPEN_ACCEPT
or OPEN_REJECT.
Observable Results: Verify that 1msec after transmitting the OpenAddress frame, the DUT transmitted BREAK.
