2.5.7 Fibre Channel over Ethernet
Fibre Channel over Ethernet (FCoE) allows for the convergence of Fibre Channel and
Ethernet traffic onto a single adapter and a converged fabric.
Figure 2-16 compares existing Fibre Channel and network connections and FCoE
connections.

Table 2-13 on page 47 lists the available Fibre Channel over Ethernet Adapter. It is a
high-performance, Converged Network Adapter (CNA) using SR optics. Each port can
simultaneously provide network interface card (NIC) traffic and Fibre Channel functions.
