▼ -> Change Connection Mode: There are Loop / Point-to-Point / Fabric options.
。
Point-to-Point (FC-P2P): Two devices are connected directly to each other. This is the simplest
topology, with limited connectivity.
。
Loop (Arbitrated Loop)(FC-AL): In this design, all devices are in a loop or ring, similar to token
ring networking. Adding or removing a device from the loop causes all activity on the loop to be
interrupted. The failure of one device causes a break in the ring. Fibre Channel hubs exist to
connect multiple devices together and may bypass failed ports. A loop may also be made by
cabling each port to the next in a ring.
。
Fabric (Switched Fabric)(FC-SW): All devices or loops of devices are connected to Fibre Channel
switches, similar conceptually to modern Ethernet implementations. Advantages of this
topology over FC-P2P or FC-AL include.
