Fiber Channel Over Ethernet (FCoE)

Definition - What does Fiber Channel Over Ethernet (FCoE) mean?

Fiber Channel over Ethernet (FCoE) is a protocol that encapsulates Fiber Channel (FC) frames over Ethernet networks. FCoE relies on storage area network (SAN) mapping without Ethernet forwarding dependence for robust and reliable SAN performance. FCoE utilizes 10 gigabit (Gb) Ethernet networks and fully adheres with FC protocol requirements. FCoE links to networks via converged FC host bus adapters and/or Ethernet network interface cards (NIC). FCoE provides FC-2 layer transfer for upper FC-3 and FC-4 layer transmission and replaces FC0 and FC1 Ethernet stack layers. FCoE does not function in routed Internet Protocol (IP) networks. Many storage and network vendors support FCoE, which is a standard component of the International Committee for Information Technology Standards (INCITS) T11 FC-BB-5.

Techopedia explains Fiber Channel Over Ethernet (FCoE)

FC is a dominant storage solution that delivers viable input/output (I/O) consolidation and maintains FC security, latency and traffic management. FCoE deploys easily, depending on organization and product requirements. The three key FCoE components are as follows: Native FC encapsulation into Ethernet frames FC replacement of lossless Ethernet media access control (MAC) addresses Ethernet extensions, which enable lossless fabric FCoE features are as follows: Operates in the network protocol stack Requires Ethernet standard enhancements for flow control support Ethernet bypasses industry consolidation protocols One time only Ethernet wiring Enables FC network device frame transmission at data transfer rates (DTR) of over 10 gigabits per second (gbps) Simplifies user engagement Integrates FC network and management software FCoE requires the following FC extensions: FC encapsulation into Ethernet frames FC N_port identification and Ethernet MAC address mapping Ethernet extensions for lossless Ethernet fabric during congestion
