Choose a metric for which to set an upper limit.
When setting upper limits, the I/O control settings dialog gives you the option of applying one of the following metrics:
- IOPS: Use if the target volume is issuing a high number of I/O requests. The maximum value is 65,535 IOPS.
- Transfer Rate [MBps]: Use if the target consumer's I/O requests are small in number but large in data size. The maximum value is 31 MBps.
To confirm the result after setting upper limits, track the task status in the History tab in the Operations window.
