Fiber Channel Over Ethernet Fcoe

Fibre channel over ethernet fcoe is a computer network technology that encapsulates fibre channel frames over ethernet networks.

Fiber channel over ethernet fcoe.

The specification was part of the international committee for information technology standards t11 fc bb 5 standard published in 2009. Fcoe utilizes 10 gigabit gb ethernet networks and fully adheres with fc protocol requirements. A classic data center design features a dedicated ethernet lan and a separate dedicated fibre channel fc san. In the past companies used ethernet strictly to share information among devices in their networks lan and they mainly relied on fibre channel for data storage san.

This allows fibre channel to use 10 gigabit ethernet networks or higher speeds while preserving the fibre channel protocol. Fibre channel over ip fcip or fc ip also known as fibre channel tunneling or storage tunneling is an internet protocol ip created by the internet engineering task force ietf for storage technology. With fcoe it is possible to run a single converged network. Fiber channel over ethernet fcoe is a protocol that encapsulates fiber channel fc frames over ethernet networks.

Fcoe requires the underlying ethernet to be full duplex and to provide lossless behavior for fibre channel traffic. Cnas utilise the fibre channel over ethernet fcoe protocol to allow storage data to be transferred in an ip packet using the same physical network as used by lan traffic. Fibre channel over ethernet fcoe solves the problem of organizations having to run parallel network infrastructures for their local area networks and their storage area networks as a result they have to operate separate switches host bus adapters hbas network interface cards and cables for each of these networks. Fcoe relies on storage area network san mapping without ethernet forwarding dependence for robust and reliable san performance.

Fcip entities are peers that communicate using tcp ip. Fcoe makes it possible to move fibre channel traffic across existing high speed ethernet infrastructure and converges storage and ip protocols onto a single cable transport and interface. There are a number of. Fcoe is short for fibre channel over ethernet.

As a standards based protocol that allows fibre channel frames to be carried over ethernet links fcoe obviates the need to run separate lan and san networks. Fibre channel over ethernet is a transport standard that takes fibre channel fc frames and encapsulates them within an enhanced ethernet network fcoe retains fibre channel upper level protocol. With fcoe it became possible for fibre channel frames to be encapsulated and transported over. Fcoe fibre channel over ethernet is a storage protocol that enable fibre channel communications to run directly over ethernet.
