[openfabrics-ewg] [Openib-promoters] Microsoft chooses not to be on Agenda at Dev. Summit

Sujal, sorry, but I disagree. But maybe I just didn't explain myself. To
my knowledge WHQL testing has been discussed many times, but because of
the complexity of the stack, it's never been agreed to. I believe
additional work on the testing process was needed.


I also disagree with your statement about MSFT and iWARP. When the issue
of iWARP came up initially I called Jim Pinkerton personally to get his
views. He said he had no choice but to come to OpenIB as an
authoritative source of a single stack for IBA. However, for iWARP, Jim
said they intended to provide support natively in their OS, so there was
nothing for us to do for iWARP support in conjunction with the Windows
stack for IBA.


AFAIK, the only work before is to get the IBA stack WHQL certified - I
don't know that there's any iWARP work to be done. I'm happy to be
proven wrong, but that's what I understand

I second Asaf on this. 

There has been significant work done on the Windows IB stack.  But just
by a handful of vendors. 

The statement about Microsoft not doing WHQL on the OFA Windows stack is
incorrect.  The statement about Microsoft supporting iWARP only is
incorrect - their Longhorn strategy is transport agnostic.  SAN
providers for Longhorn can still come from OFA - no one is precluding
it.  Someone needs to do the real work.

The OFA Windows stack as it exists today in Beta form has been used by
Microsoft in some of their CCS deployments and is being actively tested
within MS.  There is no lack of support from Microsoft.  There is
however, lack of windows developer participation in OFA, relative to
Linux. That is the crux of the problem.

We can discuss how to fix that.

As I stated earlier today, not having MS lead the panel or attend at all
has nothing to do with having a session on the OFA windows project.
Voltaire and Mellanox have been working on this project and invested
more resources than SS.  Voltaire is shipping products based on this
project and our OEMs resell it.  As part of the OFA community Voltaire
decided to discontinue its proprietary stack when this project started.
We should treat it as a viable project.

If needed Voltaire will glad to lead this discussion next week it would
be even more appropriate to do it jointly with MLNX.

Bill, thanks for raising the question. I'm a little confused by what's
happening from the earlier initiative shown by SilverStorm in developing
and then "controlling" the Windows stack, through some of their
initiatives around version control and so on. It's not clear that's
continuing on, or that it's been handed off to someone

I'm afraid working with MSFT will be frustrating. They don't seem to
want to work with us on WHQL certification, and as you know they have
their plan for iWARP support, so we'll never have something in the
Windows arena that will works as seamlessly as what we envision for

My recommendation is to continue the work we've started recently with
SDP and make it clear we'd like to engage more broadly, because we do.
An IBA solution that leaves out Windows isn't nearly as appealing as one
that includes it

I'm certainly open to other ideas

Thanks, jim

Microsoft has withdrawn their "talk" on the basis it's a primarily Linux
agenda and attendees will not be that interested. They are saying they
have an observer present.

OF Windows seems to be somewhat in a hiatus? As an Alliance we should
out what we want to do about it?

One approach might be to form a small group to work out an approach to
Microsoft to try to form a tighter collaboration between the Alliance,
se, and Microsoft as an alternative to each of the IB h/w vendors
separately with them, as it appears is now the way it is going??

Microsoft has repeated their strong interest in working with the
but there so far the evidence of that work is where????

Thoughts, please!

Inserted Or and Yaron instead of Voltaire TBDs.

As for the Windows session - I believe we should have it even if
Microsoft doesn't show up. There are issues that we need to discuss

I've addressed these points in prior e-mails, so clearly the 
information is not being received somehow.  None of us have any more 
time before SC to continue this debate.  I'll happy continue to 
discuss this over food and beverage while at SC.

So -- see you all at SC!  :-)
