Generic Port (G_Port)
Definition - What does Generic Port (G_Port) mean?
The fiber channel was developed in 1988 and approved by the American National Standards Institute (ANSI) in 1994. It is a high-speed network technology for transferring data between workstations, mainframes, PCs, storage devices, supercomputers and other peripherals. One main objective of a FC is to provide a dependable interface for a remote operating system (OS) requiring a high bandwidth.
A G_Port supports a loop topology, which requires that all links be connected and operated at the same speed.

Most FC networks transmit small computer system interface commands using fiber channel networks, like a storage area network (SAN). The SAN is used for connecting servers, backup devices and disk arrays while possessing a very reliable redundant array of independent disks. If a server fails, then the additional server can support an array with a minimal loss of data and marginal downtime.
