The VMware Device Datastore IOPS report reveals the average count of raw I/O operations per second (IOPS) for a virtual machine This report is helpful for diagnosing read and write efficiency and in some cases memory exhaustion.

High IOPS metrics can indicate virtual memory usage where RAM needs exceed allocation. Use this report together with the VM Memory Utilization and Disk Activity report.
