While the physical interfaces to systems on a Fibre Channel-based Storage Area Net- work (SAN) must be Fibre Channel, the technology can support several protocols. This diagram shows several hypothetical device-protocol combinations, such as Intelligent Peripheral Interface protocol (IPI) and High-Performance Parallel Interface protocol (HIPPI).
