Converged networks with Fibre Channel over Ethernet and Data Center Bridging

7
In the first phase of migration to converged fabrics, CNAs will connect to converged fabric access switches
that support DCB-enabled Ethernet, legacy Ethernet, and legacy FC. The CNAs will provide converged
connectivity between servers and the first-hop switch before splitting the traffic to the legacy LAN and SAN
infrastructure. Figure 6 compares traditional deployment to the first phase of converged network
deployment.
Figure 6: In phase 1 of the migration to converged fabrics, CNAs connect to converged fabric access switches.
Figure 7 shows how the next phases of deployment may occur as you update existing data centers or build
new ones. Eventually a server will require only a single pair of redundant CNAs (or a single dual-port
CNA). Converged network switches will replace separate FC, 10 GbE, and IB switches.
