An administrator is managing an environment based on two different AHV-based and ESXi-based clusters. Workloads are evenly distributed and in a healthy state.
A Linux VM running on ESXi is not performing well at the storage level and is configured as follows:
* VCPU: 8
* VRAM: 32
* vDisk: 3, first 100 GB, second 250 GB, third 250 GB
What is the easiest way to test VM performance, while minimizing downtime?
The best way to test the performance of a Linux VM that is underperforming at the storage level on an ESXi cluster, while minimizing downtime, is to migrate the VM to an AHV-based cluster. This allows leveraging Nutanix-native storage optimizations and hypervisor capabilities of AHV.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
''AHV and Nutanix storage integration is natively optimized for performance, leveraging capabilities like data locality, I/O path enhancements, and advanced metadata management. Migrating workloads from ESXi to AHV can often resolve performance bottlenecks associated with storage I/O.''
Additionally:
''Using the Nutanix Move tool, administrators can migrate running VMs between different hypervisors (e.g., ESXi to AHV) with minimal downtime and fully automated steps, reducing the operational burden.''
Increasing vCPUs would not address storage-level performance issues, and collapsing disks would require significant reconfiguration and VM downtime. vDisk sharding is not directly user-configurable and not applicable in this scenario.
