Duplex AIO = Controller (and storage and workers) on 2 nodes. There is no 3-controller option in StarlingX. So typically you would get 2 controllers and 6 workers. Pl. see:

In the standard/typical deployment, only controller-0 is PXE booted from an "external" PXE server. Other hosts PXE boot off the controller-0 on the cluster-internal mgmt/cluster network. The second link you refer to, is about PXE booting the controller-0.

But, the first link you refer to, allows PXE booting ALL nodes from an external network. I haven't tried this but it seems supported. For e.g.

In the typical deployment, once controller-0 is up, it runs a DHCP and TFTP server on the internal mgmt/cluster network. The controller-1 and other worker nodes are supposed to be configured to network boot off the NIC connected to this internal network. When they boot, controller-0 will "discover" them and add them to the host inventory.

You want more storage than controllers can provide? Pl see if this helps:
