Fibre Channel Overview

Working With Fibre Channel

Fibre Channel devices may use either of two modes: soft or hard 
addressing. Hard addressing is similar to the existing SCSI approach. 
Fibre Channel devices can only use the assigned address. If that address 
is already being used by another device, the Fibre Channel device will 
not respond to any bus activity. Soft addressing is similar to LAN 
addressing, where the system determines device addresses. As part of 
the addressing protocol, all Fibre Channel devices have one or more 
unique addresses that are not duplicated any where in the world. These 
addresses are provided by ANSI to manufactures of Fibre Channel 
products.
