= Configuring a single NUMA node policy

[role="_abstract"]
To enable the NUMA Resources Operator, configure a single NUMA node policy on your cluster. You can implement this policy by creating a performance profile or by configuring a `KubeletConfig` custom resource (CR).

[NOTE]
====
The preferred way to configure a single NUMA node policy is to apply a performance profile. You can use the Performance Profile Creator (PPC) tool to create the performance profile. If a performance profile is created on the cluster, the PPC tool automatically creates other tuning components like `KubeletConfig` and the `tuned` profile.

For more information about creating a performance profile, see "About the Performance Profile Creator" in the "Additional resources" section.
