Dell VxRail Network Planning Guide

VxRail node connectivity options

You can configure the VxRail cluster using only the Ethernet ports on the NDC or OCP if that cluster can tolerate a single point of failure and does not have demanding workload requirements. For VxRail 7.0.130 and later, on workloads that require a higher level of failure protection, VxRail supports spreading the networks across NDC or OCP Ethernet ports and Ethernet ports on PCIe adapter cards.

The custom network option provides flexibility with the selection of the Ethernet ports to support the VxRail cluster networking. You can deploy the cluster using the supported default network profiles or select the Ethernet ports for the cluster and assign those ports to the VxRail networks. There is more flexibility with customized port selections, since you can use the ports on the NDC or OCP, mix the ports from the NDC or OCP and a PCIe adapter card, or select only ports from PCIe adapter cards. For more information, see Appendix F: Physical Network Switch Examples to understand the most common node connectivity options.

If change the topology by migrating the VxRail networks onto other uplinks on the VxRail nodes, you can perform this activity after the cluster is built, if the VxRail cluster is at VxRail 7.0.010 or later.
