Typical Deployment Topologies
IOC Topology
Figure 1-3 shows a typical I/O consolidation (IOC) scenario for the Nexus 5020 switch.
Figure 1-3 I/O Consolidation Topology
The Nexus 5020 switch connects to the server ports using FCoE. Ports on the server require converged
network adapters. For redundancy, each server connects to both Nexus 5020 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 Nexus 5020 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 Nexus 5020 SAN network-facing ports 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.
