The network consists of the following major network infrastructure layouts:
- Data network infrastructure: The server NICs and the leaf switch pair. The leaf switches are connected to the data center user networks and carry the main service traffic in and out of the Reference Architecture.
- Management network infrastructure: The BMC management network, which consists of iDRAC ports and the OOB management ports of the switches, are aggregated into a one-rack unit (U) Dell EMC PowerConnect S3048 switch. This 1-RU switch in turn can connect to the data center management network.
- MAAS Services: The MAAS Rack Controllers (see below) provide DHCP, IPMI, PXE, TFTP, and other local services on the provisioning and iDRAC network. Ensure that the MAAS DCHP server is isolated from the data center DHCP server.
