Planning Considerations for Fibre Channel Topologies
94 SAN High Availability Planning Guide
Core-to-Edge Fabric
A core-to-edge fabric consists of one or more Fibre Channel directors or switches
acting as core elements that are dedicated to connecting other directors and
switches (edge elements) in the fabric. Core directors act as high-bandwidth
routers with connectivity to edge fabric elements. Figure 39 illustrates the
core-to-edge fabric topology with two core directors and fourteen edge directors
and switches (2-by-14 topology).
