 Server resources installed at the edge, such as cores, are expensive and limited. Application workloads require nearly all cores and the resources consumed by infrastructure is a key reason for the selection of a vRAN infrastructure. A hypothetical distributed unit (DU) example is an unusually resource-intensive workload, typically requiring 20 dedicated cores. Partitioning management workloads mitigates much of this activity by separating management tasks from normal workloads.
