Mesh Topology
A mesh topology describes a fabric in which each chassis has at least one port
directly connected to each other chassis in the fabric. Using 24-port QLogic
5800V Series switches, the mesh fabric shown in Figure 2-7 has the following
characteristics:
 Each link contributes up to 850MB of bandwidth between switches, 1700MB
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 ports is one chassis hop.
 Fifty-six Fibre Channel SFP ports are available for devices.
