Figure 47 (page 78) shows a converged SAN fabric with servers using CNAs connected to a
B-series CN switch and a DC SAN Director Switch 10/24 FCoE Blade.

NOTE: Consider the following for a converged SAN fabric with an FCoE blade:
• End-to-end FCoE is supported through FC ISLs.
• FCoE traffic can be carried across multiple FC ISL hops, eventually terminating in FC or FCoE
storage.
As an example, a CNA connected to the B-series CN switch on the left side can communicate with
an FCoE target connected to the B-series FCoE blade on the right, going through Fabric A or B
depending on where it is connected.
