Yes, I would be very interested. (In case you don't know, I'm the
person who ported ccd from NetBSD... :)
Well, for the list, I will release the BSDi driver. It has
some superfluous fluff associated with Bus Reset that should
be removed (The SCSI system is handed back individual error
responses for each outstanding request, no need for the
driver to resend the requests). The BSDi driver started out
under FreeBSD, but just before completion it was transfered
over and ported to the BSDi system and TTD (Tested To Death
:-). The SCSI system is different, so it has diverged
somewhat.
We have one volunteer that is willing to port the code over,
he conveniently already has some of our controllers to work
with. Anyone interested in writing a NetBSD port would be
appreciated.
I will be responsible for dealing with any issues associated
with the driver from DPT's standpoint, and would like anyone
working on this driver to keep me up to date. I will no doubt
be responsible for support ...
By the way, does DPT allow us to stripe across controllers? (I tried
looking at www.dpt.com, but could get to none of the pages....)
When we Stripe across controllers, it is done from within the
driver. It would be far better for the SCSI system writers to
place striping across controllers within that layer (as is
done under Linux).

I am not on any of the freebsd mailing lists, it is unfortunate
that I am burdened with cc:Mail here and have no hope of
keeping up with the list. However, I am very willing to answer
any questions associated with the porting efforts for the BSDi
driver!
