I'm about to propose a Birds of a Feather (BOF) session for IETF in San Francisco to discuss forming a working group (tentative name: STORM [STORage Maintenance] to update iSCSI and other IPS protocols. The primary purpose of this work would be to reflect implementation experience in the specifications - this is NOT intended to be a means of working on version 2 or even version 1.1. The initial draft of the BOF proposal follows - by the time the BOF is held (and hopefully well before, there will be a draft charter) - the purpose of the BOF meeting will be to discuss the draft charter and proposed plan of work in order to decide whether to ask that a working group be formed. I wrote this text quickly, so all suggestions for edits are welcome. A number of people have already expressed interest in the draft work items listed below - in particular, Julian Satran, Kalman Meth and Mallikarjun Chadalapaka have all indicated an intention to work on the updated iSCSI specification. Additional work items can be added - it would be useful for anyone suggesting a work item to indicate their intended role/contribution for that work item (e.g., draft author). For the implementation survey (basis for possibly taking iSCSI to Draft Standard status), I'd be interested in hearing from anyone who's interested *and* has worked on past imp Thanks, --David ------------------------------------------------------------------ Proposed Transport Area (TSV) BOF: STORM (STORage Maintenance) Proposed for IETF San Francisco (March 22-27, 2009) The IETF ips (IP Storage) and rddp (Remote Direct Data Placement) working groups have produced a number of protocols (e.g., iSCSI) that have been implemented and are being used (to varying degrees). The purpose of this BOF is to determine whether a working group should be formed for protocol maintenance and update based primarily on implementation experience. This work is envisioned to encompass: - Implementation-driven revisions and updates to existing protocols. - Interoperability reports so that some of the resulting revised protocols can be taken to Draft Standard RFC status. - Minor protocol changes or additions; this is anticipated to include iSCSI features for SAM-4 compliance and an MPA startup change needed to better support MPI applications. The work will not include wholesale changes to the existing protocols; this is not intended to be an opportunity to produce version 2 (or even version 1.1) of any of the protocols. Backwards compatibility with existing implementations will be required for all changes and additions. Initial draft list of work items: - iSCSI: Combine RFCs 3720 (iSCSI), 3980 (NAA names), 4850 (node architecture key) and 5048 (corrections/clarifications) into one document, removing features that are not implemented in practice (e.g., markers). - iSCSI: Interoperability report on what has been implemented and is known to interoperate in support of taking iSCSI to Draft Standard RFC status. The decision about whether to target Draft Standard RFC status would be discussed in the BOF in San Francisco - this may entail updates to RFC 3722 [stringprep for iSCSI] and 3723 [security]. - iSCSI: Add features to support SAM-4 (4th version of SCSI architecture) in a backwards-compatible fashion. iSCSI is currently based on SAM-2. - iFCP: The Address Translation mode of iFCP needs to be retired (SHOULD NOT implement or use), as there are problems with it, and only the Address Transparent mode of iFCP is in use. A short draft should be sufficient to do this (i.e., a complete rewrite of RFC 4172 is not anticipated). - RDDP MPA: Good support for MPI applications requires a small update to the startup functionality to allow either end of the connection to initiate. - iSER: Experience with InfiniBand implementations suggest a few minor updates to reflect what has been done in practice. Additional work (e.g., updated/improved iSNS for iSCSI, MIB changes) is possible if there's interest. I believe I have private expressions of interest or commitment to the items explicitly listed above. _______________________________________________ Ips mailing list Ips@ietf.org https://www.ietf.org/mailman/listinfo/ips
