Planning Considerations for Fibre Channel Topologies ■ Multiswitch fabric - This topology provides the ability to connect directors and edge switches through expansion ports (E_Ports) or interswitch links (ISLs) to form a Fibre Channel fabric. Director or switch elements receive data from a device; and, based on the destination N_Port address, route the data through the fabric (and possibly through multiple switch elements) to the destination device. For additional information, refer to "Planning for Multi-Switch Fabric Support" page 78, "Planning a Fibre Channel Fabric Topology" on page 97, and "Fabric Topology Design Considerations" on page 107. Planning for Point-to-Point Connectivity Point-to-point Fibre Channel topology consists of two device N_Ports communicating by a direct connection through a director or edge switch. The product-operational software provides the ability to configure a dedicated point-to-point connection by binding a director or switch port to a device World Wide Name (WWN). A dedicated point-to-point connection through a director or switch is simple to implement and should be considered for server-to-storage applications where high performance, high availability, or extended distances are required on a continual basis.
