A network technology which encapsulates fiber channel frames inside an Ethernet frame is known as fiber channel over Ethernet. Fiber channel over Ethernet is basically a data storage protocol which enables communication over Ethernet. FCoE offers “high-speed Ethernet” infrastructure to move traffic and converge IP protocols and storage to a single interface. As defined by FC-BB-5T11 group, Fiber Channel over Ethernet (FCoE) is an approach to “I/O consolidation”. Conventionally, for data storage, TCP/IP networks were used by organization. Fiber channel offers high-speed data connections between the servers and computing devices. Fiber channel over Ethernet network comprises of FC ports, adapters, cables, and FC switches, among other components. FCoE provides I/O consolidation over Ethernet and allows Ethernet and fiber channel to share an integrated, single structure. As a result, Fiber channel over Ethernet offers benefits including less cables, switch ports, and adapters, proper server virtualization and storage, and seamless integration with “FC SANs”. This also helps in minimizing network complexities in the data center.

One of the major applications of FCoE is Storage Area Networks (SANs), as it results in use of fewer cables. FCoE protocols are used by large organizations for high density storage. FCoE protocol replaces the FC1 and FC0 layers of the fiber channel with Ethernet. Fiber channel over Ethernet (FCoE) transports the stored data using fiber channel protocol as compared to TCP/IP stack. This is achieved by mapping of fiber channel over “IEEE 802.3”, creating full duplex networks. Thus, Fiber channel over Ethernet allows data centers to have increased optimization in virtualization (server) combined with reduction in cooling requirements, and lesser number of interface cards and cables.
