Welcome Bob. That is a serious development and we are looking forward at
working with you. And there is no "comitee" - just a working group and 2
chairmen (the working group is an open forum).

Subject:  IP-attached ATA storage




There was some recent discussion about supporting ATA protocols over iSCSI.
At 3ware, we have been working on IP-attached ATA storage for quite a
while.
We are already shipping a line of ATA PCI controllers with internal packet
switching  hardware that exports virtual SCSI devices, and have device
drivers for several operating systems.  We are just about to come out of
stealth mode on the way we will extend these products to network-attached
block storage subsystems with our Storage Control Protocol over TCP/IP.  We
will be showing our product at Networld+Interop in Atlanta and plan to ship
production units by the end of the year.

Although our protocol has some differences from iSCSI, we hope in the long
run to work with the committee to ensure that the final iSCSI protocol is
suitable for ATA storage as well as SCSI.  Our initial protocol, which will
ship before there is an agreed standard, will naturally be a subset of what
is eventually standardized.  We will upgrade the customers to the standard
appropriately as it emerges.
We are not quite ready to disclose our protocol, but I will be attending
the
IETF meeting in Pittsburgh and hope to begin interacting with the committee
then.
