Multistage Topology
A Multistage topology describes a fabric in which two or more edge switches
connect to one or more core switches. Each additional core switch increases the
bandwidth to each edge switch by 200 MB/s. Using 16-port SANbox 5200
switches, the Multistage fabric shown in Figure 3-6 has the following
characteristics:
 Each link contributes up to 200 MB/s of bandwidth between chassis.
Competition for this bandwidth is less than that of a cascade topology, but
greater than that of the mesh topology.
 Latency between any two ports is no more than two chassis hops.
 52 1Gbps/2Gbps Fibre Channel ports are available for devices.
