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: September 23, 2004
Test Setup: The DUT and the Testing Station are physically connected.
Test Procedure (SSP Targets):
• 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 initiator.
• The Testing Station should open an SSP connection to the DUT. The Testing Station should transmit a
Test Unit Ready command to the DUT, then close the connection.
• Wait for the DUT to open an SSP connection to the Testing Station. Allow the DUT to transmit a SCSI
Response to the Testing Station. The Testing Station should repeat this 100 times.
Observable Results: If the DUT is an initiator, verify that the Information Unit in the SSP Command frame is
between 28 and 284 bytes long. If the DUT is a target, verify that the Information Unit in the SSP Response frame
is between 24 and 1024 bytes long.
