Serial Attached SCSI, An Architecture For Linux
https://www.linuxsymposium.org/2006/view_proposal.php?hide_vote=1&content_key=2
---------------------------------
This paper would start with an overview of SCSI (SCSI-3, that is), its
object oriented nature and why such is the direction of SCSI.

Then an introduction to SAS from this SCSI point of view will be given,
i.e. where it fits in the object oriented model, why and how. There may be
very little SAS technical introduction--a couple of sentences, something
anyone would understand and something sufficient for the latter sections of
the paper.

Then an introduction to SAS as an architecture in a SCSI stack would
follow. A layered, object oriented model will be presented, similar to the
one found in my code.

This will be accompanied with a SCSI "architectural roadmap", the how and
why the architecture.

Then an overview of pure-SCSI drivers would be given (at this point the
paper talks about implementations at each layer of the software
stack). Those are implementations which hide the transport layer completely
in their firmware, and present a pure SCSI "picture", a la SAM, to the
OS. How and why they do it.

Then the paper would talk about what unifies those implementations, how it
can be done, and why it should be done this way. An introduction to SDI,
SCSI Driver Interface, would be presented. Why SDI makes sense and how it
can be done for a SCSI stack architecture in an object oriented way. Who
registers it, what they implement, how and why.

There would be a section on a SCSI/ATA Translation, SAT, and a SAT
Layer. Where it fits, how and why. What its interface is and why.

The paper would include pictures and figures as necessary to show layers,
object oriented concepts and the like.

I think you mistyped linux-scsi when you actually wanted to send this to
the OLS list?

So you would like dissenting voices to speak in forums
that nobody listens to? Am I to believe that nobody who
reads this list had a hand in the above miscarriage?

In my reply to Luben's original post, I cc-ed the
linux-kernel list. Now I can turn off the internet
and play with my new SAS box :-)

the posting is off-topic for the list. that's for certain.
if people on the OLS commitee are also on that list is irrelevant;
stalking them is not good especially if there are real venues

.. and you just added another list where the postings are off-topic.

On the face of it, the Ottawa Linux Symposium has some
explaining to do. This following quote is from:
http://www.linuxsymposium.org/2006/cfp.php

"Step 2 Committee Review"

"The programme committee will review your proposal per
 the guidelines above. Notification of acceptance or
 rejection will be sent by February 15th, 2006."

Luben, it looks like you failed at Step 2.5 (hidden):
political correctness. Perhaps OLS approved another
paper from a different author on a similar subject?

For reference here is the OLS review committee who, it
would seem, "approved" Luben's paper:
  Jeff Garzik, Red Hat Software
  Gerrit Huizenga, IBM
  Andrew Hutton, Steamballoon Incorporated
  Dave Jones, Red Hat Software
  Ben LaHaise, Intel Corporation
  Matt Mackall, Selenic Consulting
  Patrick Mochel, Intel Corporation
  Craig Ross, Linux Symposium

I can understand a rejection; I mean, last year there was already a BOF
about the topic, which makes the "newness" of the talk less. In weighing
the undoubtedly very many proposals, the OLS committee needs to make
hard choices obviously; and I can see the point of preferring new talks
over talks which cover a topic that was discussed the year before.

that to me doesn't sound like a conspiracy, but just running a
conference sanely.

Bummer... 

I was really looking forward to having this BOF this year, as I
unfortunately missed last years.
