IOC Topology

shows a typical I/O consolidation (IOC) scenario for the Cisco Nexus 5000 Series switch.

I/O Consolidation Topology

Distribution

Access Layer

The Cisco Nexus 5000 Series switch connects to the server ports using FCoE. Ports on the server require

converged network adapters. For redundancy, each server connects to both switches. Dual-port CNA

adapters can be used for this purpose. The CNA is configured in active-passive mode, and the server

needs to support server-based failover.

On the Cisco Nexus 5000 Series switch, the Ethernet network-facing ports are connected to two Catalyst

6500 switches. Depending on required uplink traffic volume, there may be multiple ports connected to

each Catalyst 6500 switch, configured as port channels. 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.

The SAN network-facing ports on the Cisco Nexus 5000 Series switch are connected to Cisco MDS 9000

Family switches. Depending on required traffic volume, there may be multiple Fibre Channel ports

connected to each MDS 9000 Family switch, configured as SAN port channels.
