SUMMARY: IP over SCSI

Original question:
Does anyone know if there are drivers written to run IP over SCSI???

Here is the data collected:
There is an RFC on this very thing:
          ftp://ftp.internic.net/rfs/rfc2143.txt

A Linux effort:
     http://lacota.interpath.net/~jfbeam/Linux/SCSI-IP/MIRROR/design/index.htm

Yet another:
     http://www.wwa.com/~scottr/sd/design/index.htm

"I believe Morningstar PPP will do PPP over SCSI." - Rick Fincher

A commercial site?
     http://www.dolphinfast.com

There is an article in the Linux Journal #52 (August 1998) on this topic.
You can probably read the article on the Linux Journal homepage
          http://www.ssc.com

And finally:
u-kevin@megami.veritas.com said the following:
If you mean "can I use a normal SCSI bus as an interprocessor link", the
answer is "sort of" - there is a slave mode interface once done someplace
that can send stuff back and forth on Solaris. (sorry the details are
fuzzy, it was a long time ago...) Dunno about Linux.

If you mean "is there a plug and play IP stack that uses the SCSI bus", I
believe the answer is no.

FC has, as part of the spec, the ability to do IP, but I don't personally
know of anybody who has implemented it yet.

More accurately - I was once involved in doing a slave mode for the Solaris
SCSA stuff, and I think it is still floating around, though I don't know
Sun's current use/availability. We used it for inter-processor communications.
Never saw an IP stack done for it.

A lot of FC implementations are really just slave mode on a Unix box that
acts like a disk to implement storage area networks. FC has the hooks for
IP, but again, I don't know of any vendor who has implemented it.
