Efficiency Policies window

You can use the Efficiency Policies window to create, display, and manage information about efficiency policies.

Command buttons

Add
Opens the Add Efficiency Policy dialog box, which enables you to run a deduplication operation on a volume for a specified duration (schedule-based) or when the change in volume data reaches a specified threshold value (threshold-based).
Edit
Opens the Edit Efficiency Policy dialog box, which enables you to modify the schedule, threshold value, QoS type, and maximum run time for a deduplication operation.
Delete
Opens the Delete Efficiency Policy dialog box, which enables you to delete the selected efficiency policy.
Status
Open a drop-down menu, which provides options to enable or disable the selected efficiency policy.
Refresh
Updates the information in the window.

Efficiency policies list

Policy
Specifies the name of an efficiency policy.
Status
Specifies the status of an efficiency policy. The status can be one of the following:
  • Enabled

    Specifies that the efficiency policy can be assigned to a deduplication operation.

  • Disabled

    Specifies that the efficiency policy is disabled. You can enable the policy by using the status drop-down menu and assign it later to a deduplication operation.

Run By
Specifies whether the storage efficiency policy is run based on a schedule or based on a threshold value (change log threshold).
QoS Policy
Specifies the QoS type for the storage efficiency policy. The QoS type can be one of the following:
  • Background

    Specifies that the QoS policy is running in the background, which reduces potential performance impact on the client operations.

  • Best-effort

    Specifies that the QoS policy is running on a best-effort basis, which enables you to maximize the utilization of system resources.

Maximum Runtime
Specifies the maximum run-time duration of an efficiency policy. If this value is not specified, the efficiency policy is run till the operation is complete.

Details area

The area below the efficiency policy list displays additional information about the selected efficiency policy, including the schedule name and the schedule details for a schedule-based policy, and the threshold value for a threshold-based policy.
