Set volume bandwidth and IOPS limits
Setting bandwidth and IOPS limits for volumes lets you control the quality of service (QoS). Bandwidth and IOPS limits are set on a per-host basis.
Prerequisites
Steps
- On the menu bar, click .
- In the list of volumes, select the relevant volume, and then click .
-
In the
Set IO limits for volume dialog box, enter the required values for
Bandwidth Limits and
IOPS Limits, or select the corresponding
Unlimited check box.
- The number of IOPS must be larger than 10.
- The volume network bandwidth is in MB/s.
- The I/O limits are applied to every mapped SDC.
- Click Apply.
- Verify that the operation has finished successfully, and click Dismiss.
