Description of Working Group:

    The IETF IPS (IP Storage) and RDDP (Remote Direct Data Placement)
    working groups have produced a significant number of storage protocols
    (e.g., iSCSI, iSER and FCIP) for which there is significant usage. The
    time has come to reflect feedback from implementation and usage into
    updated RFCs; this work may include:

    - Implementation-driven revisions and updates to existing protocols
    (i.e., updated RFCs that match the "running code").

    - Interoperability reports as needed for the resulting revised protocols
    that are appropriate for Draft Standard RFC status.

    - Minor protocol changes or additions. Backwards compatibility is required.

    Significant changes to the existing protocol standards are out of scope,
    including any work on version 2 of any of these protocols. Security for
    these protocols is based on the functionality specified in RFC 3723
    (Securing Block Storage Protocols over IP); the working group does not
    intend to make major changes or updates to that RFC.

    Stability is critical to the usage of these protocols, so backwards
    compatibility with existing implementations will be a requirement
    imposed on for all protocol changes and additions. Note that this is a
    requirement for implementation compatibility - if it is the case that
    all implementations of a protocol have done something different than
    what the RFC specifies, it is appropriate for a new RFC to document what
    the "running code" actually does and deprecate the unused original behavior.

    List of work items:

    (1) iSCSI: Combine RFCs 3720 (iSCSI), 3980 (NAA names), 4850 (node
    architecture key) and 5048 (corrections/clarifications) into one draft
    (3720bis), removing features that are not implemented in practice. This
    draft should be prepared so that it could become a Draft Standard RFC,
    but the Working Group has decided not to advance it to Draft Standard

    (2) iSCSI: Add features to support at least SAM-4 (4th version of the
    SCSI architecture) in a backwards-compatible fashion, as iSCSI is
    currently based on SAM-2. This will be a separate draft from the iSCSI
    update in the previous item. The Working Group may add additional minor
    useful iSCSI features to this draft, including features from draft
    versions of SAM-5. The iSCSI MIB (RFC 4544) should be updated to provide
    SNMP support for new features as appropriate.

    (3) FCIP: IP Protocol number 133 was allocated to a precursor of the
    FCIP protocol in 2000, but this allocated number is not used by FCIP.
    The Working Group has documented the deployed pre-standard use of this
    protocol number in RFC 6172, and IANA has updated the registry entry
    to reference RFC 6172.

    (4) iFCP: The Address Translation mode of iFCP needs to be deprecated
    (SHOULD NOT implement or use), as there are significant technical
    problems with its specification, and moreover, only the Address
    Transparent mode of iFCP is in use. This will be done via a short draft
    that updates RFC 4172, and not via a complete rewrite of RFC 4172.
    The Working Group has deprecated iFCP Address Translation mode in
    RFC 6172 and made the corresponding changes to the iFCP MIB (originally
    RFC 4369) in RFC 6173.

    (5) RDDP MPA: Good support for MPI applications requires a small update
    to the startup functionality to allow either end of the connection to
    initiate. In addition, a couple of minor changes to RDDP connection
    setup are needed based on implementation experience.

    (6) iSER: Experience with Infiniband implementations suggest a few minor
    updates to reflect what has been done in practice.

    (7) RDMA Protocol: Experience with the rddp (iWARP) RDMA Protocol
    (RFC 5040) suggests that some minor extensions are needed, specifically,
    the addition of immediate data support and remote atomic operations.

    The Working Group is expected to maintain good working relationships
    with INCITS Technical Committee T10 (SCSI standards) and INCITS
    Technical Committee T11 (Fibre Channel standards) via overlaps in
    membership as opposed to appointment of formal liaisons. The liaison
    process (including IAB appointment of a liaison or liaisons) remains
    available for use if needed.

    Recent changes in INCITS rules have removed public access to some T10
    and T11 standards documents that are expected to be needed for the WG's
    program of work. Arrangements have been made with T10 and T11 for IETF
    participants to obtain copies of specific standards their personal use
    in IETF work as needed; contact the WG chair(s) for details.
