Fibre Channel routing concepts

Fibre Channel routing concepts

Fibre Channel routing introduces the following concepts:

•

Fibre Channel router (FC router)

A switch running the FC-FC routing service. Refer to 

“Supported platforms for FC-FC routing”

 on 

page 570 for a list of platforms that can be FC routers.

•

EX_Port and VEX_Port
An EX_Port and VEX_Port function similarly to an E_Port and VE_Port respectively, but 
terminate at the switch and do not propagate fabric services or routing topology information 
from one edge fabric to another. Refer to the 

Fibre Channel over IP Administrator’s Guide

 for 

details about VE_Ports.

•

Edge fabric
An edge fabric is a Fibre Channel fabric with targets and initiators connected through the 
supported platforms by using an EX_Port or VEX_Port.

•

Backbone fabric
A backbone fabric is an intermediate network that connects one or more edge fabrics. 
In a SAN, the backbone fabric consists of at least one FC router and possibly a number of 
Fabric OS-based Fibre Channel switches (refer to 

Figure 76

 on page 575). 

•

Inter-fabric link (IFL)
The link between an E_Port and EX_Port, or VE_Port and VEX_Port, is called an 

inter-fabric link

 

(IFL). You can configure multiple IFLs from an FC router to an edge fabric.

Figure 74

 shows a metaSAN consisting of three edge fabrics connected through a Brocade DCX 

with inter-fabric links.
