Microsoft Azure Stack HCI supports switchless connections for East West traffic to a maximum of four nodes in a cluster. Refer to the cabling diagram for guidance to create a full mesh.
To configure an Azure Stack HCI networking environment using Network ATC one must create the cluster and then configure host networking using Network ATC. We would enable S2D as a final step.
This is a deviation from the legacy procedure where host networking was the first step, followed by cluster creation.
