    I submitted an Internet Draft with the subject name on behalf of a team of 
    authors.  The I-D announcement, including the abstract, is below.  This 
    draft can be obtained from: 
    "Datamover Architecture for iSCSI" (DA) describes an architectural
    model for iSCSI so that new "Datamover protocols" - such as iSER,
    see the separate announcement forwarded to the list by Mike Ko - 
    can be designed based on this architecture.   Recommended reading
    is DA, followed by iSER.  The relevant related specifications (RDMAP, 
    DDP and MPA) are currently being defined by the RDDP WG.
    Review and comments are welcome.

     Title  : Datamover Architecture for iSCSI (DA)
     Author(s) : M. Chadalapaka et al.

    iSCSI is a SCSI transport protocol that maps the SCSI family of 
    application protocols onto TCP/IP.  The Datamover Architecture for 
    iSCSI (DA) defines an abstract model in which the movement of data 
    between iSCSI end nodes is logically separated from the rest of the 
    iSCSI protocol in order to allow iSCSI to adapt to innovations 
    available in new IP transports.  The new Datamover protocol provides 
    a reliable transport for all iSCSI PDUs, but actually moves 
    the data required for certain iSCSI PDUs without involving the 
    remote iSCSI layer itself.  This document begins with an 
    introduction of a few new abstractions, defines a layered 
    architecture for iSCSI and Datamover protocols, and then models the 
    interactions within an iSCSI end node between the iSCSI layer and 
    the Datamover layer that happen in order to transparently perform 
    remote data movement within an IP fabric.  It is intended that this 
    definition would help map iSCSI to generic RDMA-capable IP fabrics 
    in the future comprising TCP, SCTP, and possibly other underlying 
    network transport layers.

    NOTE: The mail server at can return the document in
     MIME-encoded form by using the "mpack" utility.  To use this
     feature, insert the command "ENCODING mime" before the "FILE"
     command.  To decode the response(s), you will need "munpack" or
     a MIME-compliant mail reader.  Different MIME-compliant mail readers
     exhibit different behavior, especially when dealing with
     "multipart" MIME messages (i.e. documents which have been split
     up into multiple messages), so check your local documentation on
     how to manipulate these messages.
