VxRail selects the two ports on the NDC-OCP to support VxRail networking. If the NDC-OCP on the VxRail nodes is shipped with four Ethernet ports, the two leftmost ports are selected. If you choose to use only two Ethernet ports, the remaining ports can be used for other use cases. This connectivity option is the simplest to deploy. It is suitable for smaller, less demanding workloads that can tolerate the NDC-OCP as a potential single point of failure.
VxRail selects all four ports on the NDC-OCP to support VxRail networking. The same number of cable connections should be made to each switch.
In this option, two NDC-OCP ports and two ports on the PCIe card in the first slot are selected for VxRail networking. The network profile splits the VxRail networking workload between the NDC-OCP ports and the two switches. It splits the workload on the PCIe-based ports between the two switches. This option ensures against the loss of service with a failure at the switch level. It also ensures against a failure in either the NDC-OCP or PCIe adapter card.
