How FC target nodes connect to the network
Storage systems and hosts have adapters so they can be directly connected to each other or to FC switches with optical cable. For switch or storage system management, they might be connected to each other or to TCP/IP switches with Ethernet cable.
When a node is connected to the FC SAN, it registers each of its ports with the switch’s Fabric Name Server service, using a unique identifier.
