A SCSI host issues a command to the router.
The SCSI controller in the router interprets the command and places it in
buffer memory.
The router processor interprets data and programs the router Fibre
Channel controller to process the transaction.
The router Fibre Channel controller translates data into an FCP protocol
packet and sends it to the Fibre Channel target.
The Fibre Channel target interprets the FCP protocol packet and executes
the command.
