1
A SCSI host issues a command to the router.
2
The SCSI controller in the router interprets the command and places it in
buffer memory.
3
The router processor interprets data and programs the router Fibre
Channel controller to process the transaction.
4
The router Fibre Channel controller translates data into an FCP protocol
packet and sends it to the Fibre Channel target.
