Fabric Shortest Path First (FSPF) is a routing protocol used in SANs to ensure the shortest and most efficient path for data within the network. By using FSPF, the latency in a SAN can be minimized by automatically selecting the best path for data traffic. This is particularly important in a full mesh topology, where multiple paths are available between switches, as it optimizes traffic flow and reduces the chances of bottlenecks.
