How should an administrator address NCC health check errors of latency exceeding 200ms in a Nutanix cluster?

To tackle health check errors related to latency exceeding 200ms in a Nutanix cluster, replacing the switch fabric extenders with 10G line rate switches is an effective solution. This approach directly addresses the underlying cause of latency, which often stems from inadequate network bandwidth.

In a hyper-converged infrastructure like Nutanix, the communication between different nodes is critical for performance. When the current switch fabric extenders are unable to provide sufficient throughput, they can become a bottleneck, leading to increased latency. By upgrading to 10G switches, the data transfer rates are significantly improved, allowing for better handling of the data traffic within the cluster. This enhancement not only resolves current latency issues but also future-proofs the infrastructure against potential increases in workload and data volume.

Network configuration and capacity are foundational to maintaining optimal performance in a Nutanix environment, and addressing issues at the switch level can have a profound impact on overall cluster health and responsiveness.
