Multistage Topology

A Multistage® topology describes a fabric in which two or more edge switches connect to one or more core switches. The Multistage fabric shown in Figure 3-3has 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.

26 Fibre Channel ports are available for devices

	Core Switch
Edge Switch	Edge Switch
	Edge Switch
