Dave,

Thanks for filling in the details I was missing about the TOE history.

Glad to see you laugh about the ski stuff.  I thought about snowboarding
then realized I would make a great mogal for someone to do an ali off.  If
you are open to questions about TOE/RDMA stuff, would like to chat with
you and see your POV on the subject.

Luben,

Reading Dave's points above tends to point to adaptec's current direction,
as we all know. TOEs were rejected.

I stated I would help with SAS adoption because there is a SAS-Transport
model.  I asked about a possible libadaptec + libsas, and still waiting to
see if you and adaptec are up for the task.  Right now the only path open
is the one Jeff Garzik is putting forward along with James and Christop.
I have a vested interest in seeing SAS-Transport, otherwise I would have
cut and run a long time ago.

These long email threads where everyone is shout from the top of their
hill never wins anything.  After a while the hill becomes flat (from all
the stomping), and you become old and tired.

LSI pointed out they mask there SAS in firmware and make it show up in a
scsi-like or scsi state.  They also pointed out other vendors have taken
this road.  Even if Adaptec did not go this way in hardware, there still
has to be a way to map into SCSI ... sheesh this is Adaptec known for
SCSI.

Just an FYI, would suggest you cool your heels and listen for the quiet
responses.  There is more heat than light right now; maybe this thread
will offset some of the cost in the energy criss.  Will pass on advice
handed to me (when I was a maintainer) relax and listen, nobody is out to
get you (and they were right).

Cheers,

Andre

PS I didn't listen to that advice back then, don't make the same mistake.
