The previous chapter outlined the APEX Cloud Platform for Azure with PowerFlex requirements at a high level. This section shares the precise details of this configuration as built in the Dell labs.
Dell engineers performed the testing and validation using three MC-760 Azure Stack HCI nodes and four PowerFlex R760 custom nodes, as depicted in the following figure. During the validation efforts, Dell engineers considered both the ToRs and aggregation layers of the network infrastructure.

The following figure depicts the host networking configuration and connectivity to the ToRs for both the MC nodes and PowerFlex nodes:
