Test 9.1.3 - SSP Frames Structure – NUMBER OF FILL BYTES

Purpose: To determine that the DUT properly sets the NUMBER OF FILL BYTES field.

References:

9.2.1 SAS Standard

Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target. If the DUT is a SAS Intiator,
software capable of generating SCSI commands.

Revision History: April 11, 2005

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):

• Wait for the DUT to open an SSP connection to the attached SAS target. Allow the DUT to transmit a

SCSI WRITE command to the Testing Station. The target should respond with XFER_RDY and wait
for the DUT to transmit DATA frames.

Observable Results: If the DUT is an initiator, verify that the NUMBER OF FILL BYTES field in the SSP
Command frame is set to 0.
