A consultant deploys a new ESXi-based Nutanix cluster and migrates a sphere deployment to the cluster, After completing the deployment, the customer states they are experiencing VM performance issues.
Upon observing logs and performance data, the consultant identified the following symptoms.
Excessive read/write 1/Os on CVMs
Excessive Motion of VMs
What is causing this issue?
The customer is experiencing VM performance issues characterized by excessive read/write I/Os on CVMs and excessive motion of VMs due to the Distributed Resource Scheduler (DRS) in an ESXi-based Nutanix cluster. This is likely caused by the DRS migration threshold being set to Aggressive, which leads to frequent rebalancing of workloads across the cluster, causing high I/O and VM motion. Adjusting this setting to a less aggressive level can help reduce unnecessary VM motions and stabilize performance. Reference: Nutanix Bible, Nutanix University NCS-Core 6.8 learning materials
