Converged networks with Fibre Channel over Ethernet and Data Center Bridging

18
This is 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 disaggregating the traffic to the
legacy LAN and SAN infrastructure. Figure 12 compares traditional deployment to the first phase of
converged network deployment.

Figure 13 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. Converged network
switches will replace separate FC, 10 GbE, and IB switches.
