Mesh Topology
A mesh topology describes a fabric in which each chassis has at least one port
directly connected to every chassis in the fabric. The mesh fabric shown in
Figure 3-2 has the following characteristics:
■ Each link contributes up to 200 MB/s of bandwidth between switches, 400
MB/s in full duplex. Because of multiple parallel paths, there is less
competition for this bandwidth than with a cascade or a Multistage topology.
■ Latency between any two device ports is no more than two chassis hops.
■ 20 Fibre Channel ports are available for devices
