Re: iSCSI: Require iSCSI to use packet formats similar to FC, etc??

[julian_satran@il.ibm.com]

It doesn't add too much (as Robert had so many misgiving about the
performance statements).
I could not find any other two SCSI transports that have similar formats
(even on serial buses - SBP, SST and FCP are
very dissimilar).  As for gateway - remapping is the least of their issues
- state is the major one and we went a long way to minimize this for the
only other relevant serial-SCSI protocol - FCP.  I don't see why we should
make this a requirement.

Robert Snively proposes that the iSCSI Requirements document include the
following requirement WRT gateway devices:

   iSCSI MUST use packet formats similar to the common
   packet formats used by other packetized SCSI protocols where
   possible to allow both simple bridging gateways and more
   sophisticated translating gateways.
