Multistage Topology
59021-06 A
Edge Switch
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
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.
52 Fibre Channel ports are available for devices
has the following characteristics:
