Help me whats the difference between a core and a backbone switch?
Appreciated if explained in detail.
The difference is in the role these switches are playing in the SAN.
Typically a backbone product (DCX, DCX-4S, DCX8510-8, DCX8510-4) play a role of Core switch in Core/Edge Topology.
With integrated license installed, any combination of FOS switches and routers can make up the backbone fabric in FC-FC Routing.
