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. The Multistage fabric shown in
Figure 3-3 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 device ports is three chassis hops.
■ 26 Fibre Channel ports are available for devices
