The Dell EMC Ready Architecture for Red Hat OpenStack Platform uses 2 x S5232F-ON as Leaf switches and the S3048-ON (S4048-ON optional) as the management switch.
The network consists of the following major network infrastructure layouts:
- 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.
