centralizing physical security and administration of your network. For high-speed 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 blade switches provide preferential treatment for certain data streams. They
segment traffic streams into different paths for processing. Security features on the blade switch
ensure rapid handling of packets.
Fault tolerance from the server racks to the core is achieved through dual homing of servers
connected to the blade switches, which have redundant Gigabit EtherChannels.
Using dual SFP module uplinks from the blade switches provides redundant uplinks to the network
core. Using SFP modules provides flexibility in media and distance options through fiber-optic
connections.
