FCF+NPV Networking

FCF+NPV 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. A SAN allows a maximum of 239 switches. When more edge switches are required, NPV switches can be deployed. As shown in Figure 2-23, NPVA functions as an access switch and needs to forward LAN, SAN, and Inter-Process Communication (IPC) traffic. FCFA serves as an aggregation switch and needs to forward SAN traffic. To ensure link reliability between ServerA and Array, two links are deployed: ServerA-NPVA-FCFA-Array and ServerA-NPVB-FCFB-Array. CE series switches only support single-hop FCF.

Figure 2-23 Typical networking of the FCF and NPV switch (FCoE interface)

As shown in Figure 2-24, the FCF and NPV use FC interfaces to connect to storage device and servers.


Only CE8860EIand CE6850U-HI support FC interfaces.
