deployment architecture overview

The Telco RAN distributed unit (DU) 4 reference design configures an OKD 4 cluster running on commodity hardware to host telco RAN DU workloads. It captures the recommended, tested, and supported configurations to get reliable and repeatable performance for a cluster running the telco RAN DU profile.

deployment architecture overview

You deploy the telco RAN DU 4 reference configuration to managed clusters from a centrally managed RHACM hub cluster. The reference design specification (RDS) includes configuration of the managed clusters and the hub cluster components.
