Easily scalable, balanced architecture Redundant core switches mean no single point of failure Efficient use of E_Ports and ISLs More ports are now available for devices
In a core-edge design, one or more core switches are used to connect to other edge switches, while the nodes are attached to the edge switches. This allows the edge switches to accommodate higher numbers of devices.
Typically multiple core or cross-connect switches are used for redundancy. Benefits:
• Easy scalability and enhanced performance • If more devices need to be connected to the fabric, more edge switches can be added
• If more performance is needed, more cross-connect core switches can be added
• Maintains a 2-hop count from any device to any other device. • Can allow re-deployment of smaller fabric switches as edge switches
