Agreed- but it's not quite fair to state that it's 300$- it is 300$ *plus*
per-port costs for a Gig Hub, right?
The only reason for doing IP over FC is if you already have a SAN for
FC-SCSI in place, and if that is the case, there's no particularly great
reason to use the FC-IP ULP because of the addeded software nonsense for
