HP e1200-160 manual Scsi to Fibre Channel Protocol Process, StorageWorks Router

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.
