This section of the reference architecture is focused on the on-premises deployment (model B), where the centralized services, such as ACP, might be deployed to the central cluster.
This section provides the network information about physical network design.
For Dell Private Wireless, a two-tier spine and leaf network architecture is used. In this network architecture, leaf switches are uplinked to a spine switch. The leaf switches provide connectivity between the nodes in the VxRail cluster. The spine switch provides high-speed interconnectivity between the leaf switches. The spine and leaf network is connected in a full mesh using NIC bonding, providing predictable communication and latency between endpoints as well as network failover. Leaf switches are configured as a Virtual Link Trunking pair that enables all connections to be active while providing fault tolerance. The management switch provides the external connectivity to every node's iDRAC interface in the cluster for Out-of-Band (OOB) management, and the management switch is also uplinked to the spine switch.
In this reference architecture, a S4148T-ON switch is used as a management switch, two Dell Networking S5232-ON switches are used as leaf switches, and a single Dell Networking Z9264F-ON switch is used as the spine switch.
Dell Private Wireless edge sites have a simplified network architecture that includes a single leaf switch and a single management switch. Uplink these two switches to integrate with your existing infrastructure, providing the ingress or egress required by the edge node services and workloads deployed to them. The management switch provides the external connectivity to every node's iDRAC interface in the edge site for OOB management and the leaf switch is used for radio and core network connection.
For each edge site, a S4148T-ON switch is used as a management switch, and a single Dell Networking S5232-ON switch is used for control and user plane separation (CUPS) network traffic.
The typical physical network topology for edge sites (as shown in the following figure) includes these features:
Dell Private Wireless edge nodes have flexible networking options. Networking is typically broken out into the following areas:
