A Fibre Channel host issues an encapsulated FCP protocol

The router Fibre Channel controller interprets the Fibre Channel

information, and places the packet in buffer memory.
The router interprets the Fibre Channel information packet and

programs the router SCSI controller to process the transaction.
The router SCSI controller sends the command to the SCSI device

(target).
The SCSI target interprets the command and executes it.
