Setting IO Thresholds

Last published : Jun 19, 2026
Management Server console lets you select specific volumes to construct App VGs as required for an application. You can create multiple App VGs per application. You can specify a different IO threshold for each App VG. You can create App VGs based on the I/O requirements of the application. For example, the redo log volumes of a database application may need a different IOPS threshold, as compared to the archive volumes.
The maximum IOPS threshold determines the maximum number of I/Os processed per second collectively by all the volumes in an application volume group. If the combined IO requests to the App VG exceed the maximum IOPS value, Arctera Volume Manager throttles the IO requests.
In clustered environments, the IOPS threshold for an App VG is propagated to all nodes in the cluster. The threshold applies independently to each node.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.
To set the IO threshold for an App VG
  1. In the Management Server console, go to the Server perspective and expandManage in the left pane.
  2. Expand Applications, and expand** Databases to locate the database. In the Volumes tab, select one or more volumes, right-click, and select Set IO Thresholds**.
  3. In the Set IO Threshold panel, specify the Maximum IOPS value, specify an** App VG name , and click OK**.
