ExhibitYou have a 2-node FAS8300 switchless cluster.

The performance capacity report shows the current and optimal performance metrics for the CPU resource on each node of the cluster. The current metrics reflect the actual workload on the resource, while the optimal metrics reflect the workload that would result in the best performance. The performance capacity, or headroom, is the difference between the current and optimal metrics. A low or negative headroom indicates that the resource is over utilized and may experience performance degradation. The exhibit shows that both nodes have negative headroom for the CPU resource, which means that the CPU has been over utilized. A storage failover event will cause performance issues, as the surviving node will have to handle the workload of both nodes, which will further reduce the headroom and increase the latency. References :- Identify remaining performance capacity, What is Performance Capacity in ONTAP 9 and Unified Manager?
