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.
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:
FCoE features are as follows:
FCoE requires the following FC extensions:
