Let me be a little more detailed. If your SATL is in S/W on a Intel based host, then you would expect the CDB (SRB on Windows) to be in the standard buffer format for the processor. However, if the SATL is in HW on a SAS bus, then you would transmit the buffer in the manner required by the underlying transport. I believe this to be the original intent. Hope that helps. ________________________________ From: owner-t10@t10.org [mailto:owner-t10@t10.org] On Behalf Of Gary.Franco@emulex.com Sent: Wednesday, January 10, 2007 1:57 PM To: t10@t10.org Subject: Question regarding SCSI ATA Passthrough byte ordering All, Have a question with regard to byte ordering in the host for data destined to be transmitted or received from a SATA device using SAT. Should the data while it exists in the application client buffer be in network byte order (or big endian if you prefer to think of it that way) or should it be in the target devices byte ordering. __________________________________ Gary Franco Consultant Engineer Emulex Network Systems 972-671-7433 Dallas Office 972-671-7435 Dallas Office Fax 720-652-6387 Longmont Colorado Office 720-494-1817 Longmont Colorado Office Fax 972-839-5694 Cell Phone Today's Quote The mind is like a parachute.
