A new IETF working group has been formed in the Transport Area. For additional information, please contact the Area Directors or the WG Chairs. STORage Maintenance (storm) ---------------------------------- Last Modified: 2009-08-04 Current Status: Active Working Group Chairs: - David L. Black <black_david@emc.com> - Tom Talpey <ttalpey@microsoft.com> Transport Area Director(s): - Magnus Westerlund <magnus.westerlund@ericsson.com> - Lars Eggert <lars.eggert@nokia.com> Transport Area Advisor: - Lars Eggert <lars.eggert@nokia.com> Mailing Lists: General Discussion: storm@ietf.org To Subscribe: storm-request@ietf.org In Body: (un)subscribe Archive: http://www.ietf.org/mail-archive/web/storm/index.html 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. 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. Initial 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 it is up to the to decide whether to advance it to Draft Standard. (2) iSCSI: Add features to support 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 bullet. The Working group may add additional minor useful iSCSI features to this draft. (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 will consider whether this allocated number should be returned to IANA for future reallocation. (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. A combined draft is expected that encompasses items (3) and (4). (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. (6) iSER: Experience with Infiniband implementations suggest a few minor updates to reflect what has been done in practice. 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. Goals and Milestones: June 2009 First version of FCIP protocol number and iFCP Address Translation mode draft July 2009 First version of iSCSI SAM-4 (and other) new features draft. Aug 2009 First version of RDDP MPA startup change draft Sep 2009 Working Group Last Call on FCIP protocol number and iFCP address change draft Sep 2009 First version of combined iSCSI draft (3720bis) Oct 2009 First version of iSER update draft Oct 2009 Working Group Last Call on RDDP MPA startup change draft. Dec 2009 Functionally complete iSCSI SAM-4 (and other) new features draft. Feb 2010 Working Group Last Call on iSER update draft March 2010 Working Group Last Call on iSCSI SAM-4 (and other) new features draft. April 2010 Working Group decision on whether to seek Draft Standard RFC status for the combined iSCSI draft (3720bis). [Note: decision may be made significantly before this date.] Sep 2010 Working Group Last Call on combined iSCSI draft (3720bis) _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
