SCSI to Fibre Channel Protocol Process
In this example, a SCSI host (initiator) on the SCSI bus issues commands and the
information is passed through the router to a target on the Fibre Channel Storage
Area Network (FC-SAN).
Figure 4 is an illustration of the process and Table 4
defines each step.

Item Description
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.
5 The Fibre Channel target interprets the FCP protocol packet and executes
the command.
