What is FC-Fabric?

Fibre Channel (FC) is a high-speed data transfer protocol (commonly running at 1, 2, 4, 8, 16, 32, 64, and 128 gigabits per second rates) providing in-order, lossless delivery of raw block data. Fibre Channel networks form a switched fabric because the switches in a network operate in unison as one big switch. An FC fabric is a switched network topology that interconnects FC devices using FC switches, usually to create a SAN. An FC switch is a Layer 3 network switch that is compatible with the FC protocol, forwards FC traffic, and provides FC services to the components of the FC fabric.
