[Ips] Proposed Storm WG Charter

[Black_David at emc.com]

The proposed WG charter for the Storm WG is attached.

The major changes from the charter discussed at the
storm BOF in San Francisco are:
- Deferred decision on whether to take iSCSI to Draft
	Standard RFC status; the WG gets to decide
	(i.e., it's not an up-front commitment to seed
	 Draft Standard RFC status).
- Added some text about maintaining good informal working
	relationships with T10 and T11; the formal IETF
	Liaison process is available as a last resort, but
	this is not the best way to get things done.
- There are a set of goals and milestones.

I have expressions of interest from draft authors for all
six of the work items listed on this draft charter.

If you have any concerns about this charter or want to
comment on it, please speak up ASAP, ... BUT ...

... the forum for discussion of this charter is the new
storm at ietf.org mailing list - if you're interested,
please join that list and make sure your comments go
there.  The list archives should be available on-line.

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.

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.
