- Core network infrastructure - The connectivity of aggregation switches to the core for external connectivity.
- Data network infrastructure - The server NICs, Leaf switches, and the aggregation switches.
- Management network infrastructure - The BMC management network, consisting of iDRAC ports and the out-of-band management ports of the switches, is aggregated into a 1-rack unit (RU) S3048-ON switch in one of the three racks in the cluster. This 1-RU switch in turn can connect to one of the aggregation or core switches to create a separate network with a separate VLAN.
