Efficiency Policies window

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.
