[imss] STORM proposed charter - 31 May 2009 version

[Black_David at emc.com]

What I believe is the final draft of the proposed charter
for the STORM WG is attached; I've done a bunch of editing
and added the info about T10 and T11 doc access.  This is
about to go out for wider review.

Also, a reminder that STORM discussion will stop cc:'ing
other mailing lists soon.  If you're interested in STORM
work, please subscribe to the storm at ietf.org mailing list:
https://www.ietf.org/mailman/listinfo/storm

Finally - this is a near-final reminder that the rddp at ietf.org
mailing list will be closing soon - all discussion of RDDP
protocols will move to the storm at ietf.org mailing list.

Thanks,
--David

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, making
backwards compatibility with existing implementations a requirement
for all protocol changes and additions.  This is a requirement for
implementation compatibility - if all implementations of a protocol
have done something different than what the RFC specified, then it
is appropriate for a new RFC to document what the "running code"
actually does and deprecate the unimplemented 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 WG to decide
	whether 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 that allocated number is not
	used by FCIP.  The working group will consider whether that
	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 it as specified in RFC
	4172, and moreover, only the Address Transparent mode of iFCP
	is in use.  This change is to be done via a short draft that
	updates RFC 4172, as opposed to a complete rewrite of RFC 4172.
	A combined draft is expected that encompasses items (3) and (4);
	this draft should also update the iFCP MIB (RFC 4369) to
	deprecate support for iFCP Address Translation mode.
(5) RDDP MPA: Good support for MPI applications requires a small
	update to MPA startup functionality to allow either end
	of the connection to initiate.
(6) iSER: Experience with Infiniband implementations suggests 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.

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.
