Server aggregation (Figure 1-2)—You can use the switches to interconnect groups of servers,
centralizing physical security and administration of your network. For high-spee d IP forwarding at
the distribution layer, connect the switches in the access layer to multilayer switches with routing
capability. The Gigabit interconnections minimize latency in the data flow.
QoS and policing on the switches provide preferential treatment for certain data streams. They
segment traffic streams into different paths for processing. Security features on the switch ensure
rapid handling of packets.
Fault tolerance from the server racks to the core is achieved throug h dual homing of servers
connected to switches, which have redundant Gigabit 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.
