Background
FC (Fibre Channel) is a high-speed network technology standard, mainly used for Storage Area Networks (SANs) of commercial data centers. Fibre channel networks form a switching fabric because they work in concert as one large switch. Fibre channel typically runs over fiber optic cables inside and between data centers. Most block stores run over a fibre channel fabric and support many upper layer protocols. From the perspective of the layered protocol stack, FC contains only the specification from the physical layer to the transport layer. Its upper layers define interfaces that encapsulate other protocols as application layer protocols, such as SCSI or IP protocols. And the whole protocol is FCP (FC protocol) after SCSI3 is packaged. The Fibre Channel Protocol (FCP) is a transport protocol that transports SCSI commands primarily over fibre channel networks. The host computer runs FICON commands set through the fibre channel due to its high reliability and throughput. Fibre channel may be used for flash memory transmitted over NVMe interface protocol.
