Test 9.4.2 - SSP XFER_RDY IU – REQUESTED OFFSET Large Transfer
Purpose: To determine that the DUT, an SSP Target port, properly sets the DATA OFFSET field when transmitting
DATA frames.

9.2.2.3 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator.
Revision History: September 27, 2004
Test Setup: The DUT and the Testing Station are physically connected. The DUT is not power on.
Test Procedure (SSP Target):
• Power on the DUT.
• 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 a SAS Initiator.
• The Testing Station should open an SSP connection to the DUT and transmit a SCSI WRITE
command for 65536 bytes. Close the connection
• Allow the DUT to open an SSP connection to the Testing Station and transmit XFER_RDY, SCSI
response frame to the received command.
Observable Results: Verify that for each XFER_RDY frame, the DUT sets the REQUESTED OFFSET field to the
REQUESTED OFFSET value of the previous XFER_RDY frame plus the WRITE DATA LENGTH field of the
previous XFER_RDY frame.
