In this mode, the NUMA Resources Operator creates one scheduler replica for each control-plane node in the cluster to ensure redundancy. This default behavior occurs if the `spec.replicas` field is not specified in the NUMAResourcesScheduler Custom Resource (CR). Alternatively, you can explicitly set a specific number of scheduler replicas to override the default HA behavior or disable the scheduler entirely by setting the `spec.replicas` field to `0`. + +This feature is available as a technology preview.
