MultiStage Topology
A Multistage™ topology describes a fabric in which two or more edge switches
connect to one or more core switches. Using 20-port SANbox 5802V switches, the
Multistage fabric shown in Figure 3-8 has the following characteristics:
Each link contributes up to 850 MB 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.
Seventy-two Fibre Channel SFP ports are available for devices.
