FCoE configuration example (in IRF mode)
Network requirements
As shown in Figure 37 :
• Switch A and Switch B are connected to an Ethernet switch, and operate at the access layer of the
LAN.
• Switch A and Switch B are connected to Switch C and Switch D, respectively.
• The four switches operate as the FCF switches of the SANs.
Configure FCoE to meet the following requirements:
• The transmission network formed by Switch A, Switch B, and the Ethernet switch can use the server
to provide services for the LAN. The transmission network formed by switches A through D can
enable the server to access the disk device.
• Link backup is used to implement high availability for the packets to and from the server and disk
device.
• The bandwidth is increased for the link between Switch A and Switch C and the link between Switch
B and Switch D. Link backup and load sharing are implemented.
• Switch A and Switch B are uniformly managed, and the hardware resources and software
processing capabilities of the two switches are integrated. When one switch fails, the other switch
can quickly take over to avoid service interruption.
