Test 9.1.2 - SSP Frames Structure – Information Unit
Purpose: To determine that the DUT does not transmit an SSP frame with an Information Unit exceeding 1024
bytes.
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 commands to the target. The DUT should transmit at least 50 commands.
• The target should respond to each received command with SCSI Response with status GOOD.
Observable Results: Verify that the Information Unit in the SSP Command frame is between 28 and 284 bytes
long.
