Title : Datamover Architecture for iSCSI (DA)
Author(s) : M. Chadalapaka, et al.
Filename : draft-ietf-ips-iwarp-da-04.txt,.pdf
Pages : 65

iSCSI is a SCSI transport protocol that maps the SCSI family
of application protocols onto TCP/IP. 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. While DA defines the architectural functions
required of the class of Datamover protocols, it does not
define any specific Datamover protocols. Each such Datamover
protocol, to be defined in a separate document, 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 such as InfiniBand.

NOTE: The mail server at ietf.org 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
