3.5. Topologies
3.5.1. Point-to-Point
The first topology to discuss is the simplest. It is called a point-to-point topology. It is two nodes (devices) connected together. One node could be a computer system and the other node could be a disk array.
Figure 3-3. Point-to-Point Topology
This topology uses two nodes (each node must have at least one port), and the nodes are connected using one link or cable. The point-to-point connection guarantees instant access with no interference from any other node or application.
If a peripheral node, such as a disk array, has two N_Ports, access to the disk array could be shared between two computer systems. ...
