 `HighNodeUtilization`:: This profile attempts to place as many pods as possible on to as few nodes as possible. This minimizes node count and has high resource usage per node.

+====
+Switching to the `HighNodeUtilization` scheduler profile will result in all pods of a `ReplicaSet` object being scheduled on the same node. This will add an increased risk for pod failure if the node fails.
