Thank you for sharing those pictures from the Configuration Portal. They help illustrate your question: why doesn't the Predefined option offer the four-port configuration when you add the PCIe card? I'm not sure I have the answer to that, but with the rapid advances VxRail has made in network configuration recently, I have been advising my students to use the Custom option when there is any doubt. Your illustrations show that you can choose a four-port VDS and connect all four 25 Gbps ports in the Custom configuration--if that's what you want, you should use that. When the default card has both 1 Gbps and 10|25 Gbps ports as in your P670F selection, Predefined only selects the high-speed ports for the configuration. You should not need to perform any re-configuration prior to install as long as at least one of vmnic0 to vmnic3 is connected at install time.   #IWork4Dell
i need to configure VxRail Cluster with 2*25 NDC ports & 2*25 PCi ports what is the best practice to use predefined profiles  connecting ports 1NDC & 2PCi to switch01 and 2NDC & 1 PCI to switch 2 ? if i go through this configuration what should i select during initial implementation 4*25 Ports ?     and if i decided to go through custom network could you please advice with required steps? is there any prepration befor doing that to ESXI hosts vSwitch ? what is the best mapping ?
