Introduction to Fibre Channel Fibre Channel Terminology Fibre Channel Terminology AL_PA: Arbitrated Loop Physical Address. Auto-select addressing: Default addressing assignment method for libraries that picks an available address and uses it as the hard address from then on. Fabric: Switched interconnect methodology that supports high-speed data routing in Fibre Channel networks. Fibre Channel: A transport protocol that allows high-speed communication among workstations, super-computers, mainframes, data storage devices, and other peripherals. Fibre Channel is capable of transmitting and receiving data simultaneously. Fibre Channel Arbitrated Loop (FC-AL): Topology that provides a low-cost solution for attaching multiple Fibre Channel ports in a loop without switches. Hard addressing: Addressing assignment method that allows you to set and maintain a fixed address. Hub: A device that provides a multiple port loop interconnect system to implement a FC-AL using a physical "star" configuration. Point to Point: Fibre Channel topology in which two Fibre Channel devices are connected together. Protocol: A data transmission convention that encompasses timing, control formatting, and data representation. Soft addressing: Addressing mode that looks for an unused address during every power cycle. Switch: A device that provides a (n by n) interconnect to allow a port to have full communication bandwidth with any other port while other communications are occurring. Topology: The logical arrangement of nodes on a network. Appendix C C- 3 Fibre Channel
