VxRail nodes 15G Onboard 2x 1G copper NIC ports
Anyone know why these ports where fitted to 15G nodes? What is their use case in a modern server?
They scew the vmnic numbers assigned to interfaces and now there is a mix between clusters. So much for consistency in the build.

15G node has LOM and OCP NIC.
LOM(LAN on Motherboard) has 2 1GbE ports and assigned vmnic0 and vmnic1.
Usually in VxRail, it is no use of it.
You needs to consider about NIC(OCP and PCIe NICs) configration refer to below.

But what is the purpose of fixed 1G LOM? Why not have only OCP to give customer choice of interfaces like before with the NDC? The impact to VxRail is now a lack of consistency of interface naming and it will be the same for other non HCI installs too with PowerEdge.

I have to agree with the OP, adding back in 2 x 1Gb LOM ports on current gen VxRail (P & E series at least) seems like an odd step. It actually caused us some problems with a VCF on VxRail deployment as we went a bit off-script (OK that was our fault) and tried disabling them in the BIOS rather than going through the vmnic reassignment steps but then later on it's hardcoded not to allow vmnic0 or 1 to be used as vDS uplinks (as it assumes they are the 1Gb ports) so we ended up having to re-RASR and start the deployment again
