topology

With respect to FC, the configuration of the FC network and

the resulting communication paths allowed. There are three

possible topologies:

Point-to-point: A direct link between two communication

ports

Switched fabric: Multiple N_Ports linked to a switch by

F_Ports

Arbitrated loop: Multiple NL_Ports connected in a loop
