FCoE overview
Fibre Channel over Ethernet (FCoE) enables you to transport FC protocols and frames over
Converged Enhanced Ethernet (CEE) networks. CEE is an enhanced Ethernet that enables the
convergence of various applications in data centers (LAN, SAN, and HPC) onto a single interconnect
technology.
FCoE provides a method of encapsulating the Fibre Channel (FC) traffic over a physical Ethernet
link. FCoE frames use a unique EtherType that enables FCoE traffic and standard Ethernet traffic to
be carried on the same link. FC frames are encapsulated in an Ethernet frame and sent from one
FCoE-aware device across an Ethernet network to a second FCoE-aware device. The FCoE-aware
devices may be FCoE end nodes (ENodes) such as servers, storage arrays, or tape drives on one
end and FCoE Forwarders on the other end. FCoE Forwarders (FCFs) are switches providing FC
fabric services and FCoE-to-FC bridging.
