FCF+FSB Networking

FCF+FSB Networking

On a converged data center network, FCoE is used to implement network convergence. To reduce network construction costs, access switches are often deployed between servers and FCFs. As shown in Figure 2-25, FSBA is used as an access switch and needs to forward LAN, SAN, and Inter-Process Communication (IPC) traffic. FCFA serves as a core switch and needs to forward SAN traffic. To ensure that SAN traffic is correctly forwarded, FIP snooping is configured on FSBA. To ensure link reliability between ServerA and Array, two links are deployed: ServerA-FSBA-FCFA-Array and ServerA-FSBB-FCFB-Array. CE series switches only support single-hop FCF.

When both the FCF and FSB are used, you are advised to use dual-homing networking. This is because, in single-homing networking, the time required for link recovery may be excessive when the FCoE-enabled device connects to certain network adapters.

Figure 2-25 Typical FCF+FSB networking (FCoE interface)

As shown in Figure 2-26, the FCF uses the FC interface to connect to the storage device.


Only CE8860EIand CE6850U-HI support FC interfaces.
