________________________________




This is a reminder that the Storage Maintenance BOF will
be held in about 2 weeks at the IETF meetings in San Francisco.
Please plan to attend if you're interested:

THURSDAY, March 26, 2009
Continental 1&2                   TSV                   storm
Storage Maintenance BOF

The BOF description is at:
http://www.ietf.org/mail-archive/web/ips/current/msg02669.html
<http://www.ietf.org/mail-archive/web/ips/current/msg02669.html>=20

The initial agenda is here:
http://www.ietf.org/mail-archive/web/ips/current/msg02670.html
<http://www.ietf.org/mail-archive/web/ips/current/msg02670.html>=20

I'm going to go upload that initial agenda as the BOF agenda,
and it can be bashed at the meeting.

The primary purpose of this BOF is to answer two questions:
(1) What storage maintenance work (IP Storage, Remote Direct
                Data Placement) should be done?
(2) Should an IETF Working Group be formed to undertake that
                work?

Everyone gets to weigh in on these decisions, even those who
can't attend the BOF meeting.  Anyone who thinks that there is
work that should be done, and who cannot come to the BOF meeting
should say so on the IPS or RDDP mailing lists (and it'd be a
good idea for those who can come to do this).  As part of the
email, please indicate how you're interested in helping (author
or co-author of specific drafts, promise to review and comment
on specific drafts).

Here's a summary of the initial draft list of work items:
- iSCSI: Combine RFCs into one document, removing unused features.
- iSCSI: Interoperability report on what has been implemented and
                interoperates in support of Draft Standard status for
iSCSI.
- iSCSI: Add backwards-compatible features to support SAM-4.
- iFCP: The Address Translation mode of iFCP needs to be deprecated.
- RDDP MPA: Small startup update for MPI application support.
- iSER: A few minor updates based on InfiniBand experience.

Additional work (e.g., updated/improved iSNS for iSCSI, MIB changes,
updated ipsec security profile [i.e., IKEv2-based]) is possible if
there's interest.

There are (at least) four possible outcomes:
(A) None of this work needs to be done.
(B) There are some small work items that make sense.  Individual
                drafts with a draft shepherd (i.e., David Black) will
                suffice.
(C) A working group is needed to undertake more complex work
                items and reach consensus on design issues.  The WG can
                be "virtual" and operate mostly via the mailing list
                until/unless controversial/contentious issues arise.
(D) There is a lot of complex work that is needed, and a WG
                that will plan to meet at every IETF meeting should be
                formed.

Please note that the IETF "rough consensus" process requires a
working group in practice to be effective.  This makes outcome
(C) look attractive to me, as:
- I'm coming under increasing pressure to limit travel, and
                the next two IETF meetings after San Francisco are not
                in the US.
- I'd rather have the "rough consensus" process available and
                not need it than need it and not have it available.

Setting an example for how to express interest ...

---------------
I think that the iSCSI single RFC and interoperability report are
good ideas, but I want to see a bunch of people expressing interest
in these, as significant effort is involved.  It might make sense
to do the single iSCSI RFC but put off the interoperability report
(the resulting RFC would remain at Proposed Standard rather than
going to Draft Standard), as I'm not hearing about major iSCSI
interoperability issues.

I think the latter four items (SAM-4 for iSCSI, deprecate iFCP
address translation, MPI fix to MPA and iSER fixes) should all
be done.

I plan to author the iFCP address translation deprecation draft,
and review all other drafts.

I think that a virtual WG should be formed that plans to do its
work primarily via the mailing list.  I believe the SAM-4 work
by itself is complex enough to need a working group - I would
expect design issues to turn up at least there and in determining
whether to remove certain iSCSI features, but I'm cautiously
optimistic that the mailing list is sufficient to work these
issues out (and concerned that travel restrictions are likely to
force use of the mailing list).

Ok, who wants to go next?

Thanks,

<tt>Please plan to attend if you're interested:</tt><br>
<br>
<tt>THURSDAY, March 26, 2009</tt><br>

<br>
<tt>I'm going to go upload that initial agenda as the BOF =
agenda,</tt><br>
<tt>and it can be bashed at the meeting.</tt><br>
<br>
<tt>The primary purpose of this BOF is to answer two questions:</tt><br>
<tt>(1) What storage maintenance work (IP Storage, Remote =
Direct</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Data =
Placement)
should be done?</tt><br>
<tt>(2) Should an IETF Working Group be formed to undertake =
that</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; =
work?</tt><br>
<br>
<tt>Everyone gets to weigh in on these decisions, even those =
who</tt><br>
<tt>can't attend the BOF meeting. &nbsp;Anyone who thinks that there =
is</tt><br>
<tt>work that should be done, and who cannot come to the BOF =
meeting</tt><br>
<tt>should say so on the IPS or RDDP mailing lists (and it'd be =
a</tt><br>
<tt>good idea for those who can come to do this). &nbsp;As part of =
the</tt><br>
<tt>email, please indicate how you're interested in helping =
(author</tt><br>
<tt>or co-author of specific drafts, promise to review and =
comment</tt><br>
<tt>on specific drafts).</tt><br>
<br>
<tt>Here's a summary of the initial draft list of work items:</tt><br>
<tt>- iSCSI: Combine RFCs into one document, removing unused =
features.</tt><br>
<tt>- iSCSI: Interoperability report on what has been implemented =
and</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; =
interoperates in
support of Draft Standard status for iSCSI.</tt><br>
<tt>- iSCSI: Add backwards-compatible features to support =
SAM-4.</tt><br>
<tt>- iFCP: The Address Translation mode of iFCP needs to be =
deprecated.</tt><br>
<tt>- RDDP MPA: Small startup update for MPI application =
support.</tt><br>
<tt>- iSER: A few minor updates based on InfiniBand experience.</tt><br>
<br>
<tt>Additional work (e.g., updated/improved iSNS for iSCSI, MIB =
changes,</tt><br>
<tt>updated ipsec security profile [i.e., IKEv2-based]) is possible =
if</tt><br>
<tt>there's interest.</tt><br>
<br>
<tt>There are (at least) four possible outcomes:</tt><br>
<tt>(A) None of this work needs to be done.</tt><br>
<tt>(B) There are some small work items that make sense. =
&nbsp;Individual</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; drafts with =
a draft
shepherd (i.e., David Black) will</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; =
suffice.</tt><br>
<tt>(C) A working group is needed to undertake more complex =
work</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; items and =
reach
consensus on design issues. &nbsp;The WG can</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; be
&quot;virtual&quot; and operate mostly via the mailing list</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; until/unless
controversial/contentious issues arise.</tt><br>
<tt>(D) There is a lot of complex work that is needed, and a WG</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; that will =
plan to
meet at every IETF meeting should be</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; =
formed.</tt><br>
<br>
<tt>Please note that the IETF &quot;rough consensus&quot; process =
requires a</tt><br>
<tt>working group in practice to be effective. &nbsp;This makes =
outcome</tt><br>
<tt>(C) look attractive to me, as:</tt><br>
<tt>- I'm coming under increasing pressure to limit travel, and</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; the next two =
IETF
meetings after San Francisco are not</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; in the =
US.</tt><br>
<tt>- I'd rather have the &quot;rough consensus&quot; process available =
and</tt><br>
<tt>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; not need it =
than
need it and not have it available.</tt><br>
<br>
<tt>Setting an example for how to express interest ...</tt><br>
<br>
<tt>---------------</tt><br>
<tt>I think that the iSCSI single RFC and interoperability report =
are</tt><br>
<tt>good ideas, but I want to see a bunch of people expressing =
interest</tt><br>
<tt>in these, as significant effort is involved. &nbsp;It might make =
sense</tt><br>
<tt>to do the single iSCSI RFC but put off the interoperability =
report</tt><br>
<tt>(the resulting RFC would remain at Proposed Standard rather =
than</tt><br>
<tt>going to Draft Standard), as I'm not hearing about major =
iSCSI</tt><br>
<tt>interoperability issues.</tt><br>
<br>
<tt>I think the latter four items (SAM-4 for iSCSI, deprecate =
iFCP</tt><br>
<tt>address translation, MPI fix to MPA and iSER fixes) should =
all</tt><br>
<tt>be done.</tt><br>
<br>
<tt>I plan to author the iFCP address translation deprecation =
draft,</tt><br>
<tt>and review all other drafts.</tt><br>
<br>
<tt>I think that a virtual WG should be formed that plans to do =
its</tt><br>
<tt>work primarily via the mailing list. &nbsp;I believe the SAM-4 =
work</tt><br>
<tt>by itself is complex enough to need a working group - I =
would</tt><br>
<tt>expect design issues to turn up at least there and in =
determining</tt><br>
<tt>whether to remove certain iSCSI features, but I'm =
cautiously</tt><br>
<tt>optimistic that the mailing list is sufficient to work =
these</tt><br>
<tt>issues out (and concerned that travel restrictions are likely =
to</tt><br>
<tt>force use of the mailing list).</tt><br>
<br>

<tt>Ok, who wants to go next?</tt><br>
