Chapter 1 Overview
Network Configuration Examples
Fault tolerance from the server racks to the core is achieved through dual homing of servers
connected to dual switch stacks, which have redundant Gigabit EtherChannels and cross-stack
EtherChannels.
Using dual SFP module uplinks from the switches provides redundant uplinks to the network core.
Using SFP modules provides flexibility in media and distance options through fiber-optic
connections.
The various lengths of stack cable available, ranging from 0.5 meter to 3 meters provide extended
connections to the switch stacks across multiple server racks, for multiple stack aggregation.
