Fibre Channel over Ethernet
In this chapter
FCoE overview
Fibre Channel over Ethernet (FCoE) leverages Ethernet enhancements, called Data Center Bridging
(DCB), to transport encapsulated Fibre Channel frames over Ethernet. Ethernet is the physical layer
over which the encapsulated FC frames are transported.
One of the barriers to using Ethernet as the basis for a converged network has been the limited
bandwidth that Ethernet has historically provided. However, with 10 Gbps Ethernet, the available
bandwidth now offers the potential to consolidate all the traffic types over the same link.
Unlike Fibre Channel, Ethernet is not a peer-to-peer protocol. The mechanism used to discover new
ports, MAC address assignments and FC logins and logouts is called the FCoE Initialization Protocol
(FIP).
