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 16-port SANbox 5000
Series switches the mesh fabric shown in
Figure 3-7 has the following
characteristics:
„
Each link contributes up to 425 MB of bandwidth between switches, 850 MB
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.
„
40 1/2/4-Gbps Fibre Channel ports are available for devices.
