Introduction

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.
