We monitored the following resources during our testing:
VMware vCenter
VMware vCenter was used for VMware vSphere-based solutions to gather key data (CPU, GPU, memory, disk and network usage) from each of the compute hosts during each test run. This data was exported to .csv files for single hosts and then consolidated to show data from all hosts (when multiple hosts are tested). While the report does not include specific performance metrics for the Management host servers, these servers were monitored during testing to ensure they are performing at the expected performance level and with no bottlenecks.
GPU resources
We gathered GPU performance metrics directly from the vSphere client.
Resource utilization
The purpose of this test was to determine the user density at a reasonable system load. Testing to system failure was out of scope. To achieve a reasonable system load, target thresholds for system resources are set out in the following table. These thresholds reflect a system that is well utilized but not near failure.
| Metrics | Target threshold |
| Average CPU usage | 85% |
| Average CPU core utilization | 85% |
| Average CPU readiness | 10% |
| Average memory utilization (active) | 85% |
| Consumed memory | <100% |
| Memory ballooning | 0 |
| Memory swapping | 0 |
| Network throughput | 85% |
| Cluster storage latency | 20 milliseconds (ms) |
| Disk latency | 20 ms |
| Spare capacity | 15% |
| Latency (vSAN) | 20 ms |
