Dell Telecom Infrastructure Blocks for Red Hat supports radio access network (RAN) workloads for a variety of use cases, such as expanding cell networks, providing ultra-low latency connections, and distributing computing resources along the network edge. Telecom Infrastructure Blocks for Red Hat enables customers to deploy RAN workloads in a variety of topologies and workload clouds. You can deploy workload clouds in six or more-node, three-node, and single node OpenShift (SNO) clusters, depending on the required resources and location.
Centralized unit (CU) and distributed unit (DU) applications in these workload clouds can require multiple CPU cores, several gigabytes of memory, and bonded network interface controllers that comply with single root I/O virtualization (SR-IOV) standards. The workload clouds in the National Data Center, Regional Data Centers, and Local Data Centers can use Dell PowerEdge R760 servers to provide compute resources to run CU and DU applications. Cell Site workload clouds can use Dell PowerEdge XR8620t, Dell PowerEdge XR8610t, and Dell PowerEdge XR5610 servers, which can be distributed along the network edge and scaled to include one additional PowerEdge XR8620t, PowerEdge XR8610t, or PowerEdge XR5610 server in a SNO+1 cluster.
The following figure shows an example of one supported RAN topology:
