Term
What are the three fibre channel topologies?
Definition
1. Point to point
2. Arbitrated loop
3. Switched Fabric
Term
What topology is the simplest Fibre Channel topology, consisting of two directly connected node ports (N_Ports).
Definition
Point to point
Term
What topology is a uni-directional ring, similar to token ring, supporting up to 126 interconnected devices (+ the loop master)?
Definition
Aribitrated Loop
Term
What topology is an interconnection topology based on one or more interconnected Fibre Channel switches?
Definition
Switched Fabric
Term
What topology provides a low-cost connectivity between a modest number of loop ports using a shared-media and shared-bandwidth scheme?
Definition
Arbitrated Loop
Term
What topology provides low-cost connectivity between two N_Ports?
Definition
Point to point
Term
What topology provides higher-cost connectivity between a larger number of ports using a switched interconnect scheme that provides high aggregate bandwidth, isolation between ports, and better concurrent maintenance capabilities.
