Ethernet TOR Switch Topology

The Cisco Nexus 5000 Series switch can be deployed as a 10-Gigabit Ethernet top-of-rack (TOR) switch,

with uplinks to the data center LAN distribution layer switches. An example configuration in shown in

In this example, the blade server rack incorporates blade switches that support 10-Gigabit Ethernet

uplinks to the Cisco Nexus 5000 Series switch. The blade switches do not support FCoE, so there is no

FCoE traffic and no Fibre Channel ports on the Cisco Nexus 5000 Series switch.

In the example configuration, the Cisco Nexus 5000 Series switch has Ethernet uplinks to two Catalyst

switches. If STP is enabled in the data center LAN, the links to one of the switches will be STP active

and the links to the other switch will be STP blocked.

Distribution

Nexus Switch

All of the server-side ports on the Cisco Nexus 5000 Series switch are running standard Ethernet. FCoE

is not required, so the server ports are connected using 10-Gigabit Ethernet NICs.

The servers are connected to the data center SAN through MDS 9134 SAN switches. The server Fibre

Channel ports require standard Fibre Channel HBAs.
