Test 9.3.4 - SSP Data IU – NUMBER OF FILL BY TES ZERO
Purpose: To determine that the DUT, an SSP Target port, properly sets the NUMBER OF FILL BYTES field when
transmitting DATA frames.
References:
9.2.2.4 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator.
Revision History: February 7, 2005
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 a SAS Initiator.
• The Testing Station should open an SSP connection to the DUT and transmit a SCSI READ_BUFFER
command for 1539 bytes. Close the connection
• Allow the DUT to open an SSP connection to the Testing Station and transmit DATA frames and a
SCSI response frame to the received command.
Observable Results: Verify that if the DUT sets the NUMBER OF FILL BYTES field to zero in a DATA frame,
the DUT continues to transmit DATA frames for that command.
