To control the power consumption through the method of enabling policy, only the device (group) with "Enable Policy" status can be configured with

power consumption policy, as shown in the figure below:

Display "Currently Effective Policy: Holiday" in the interface, and show all the policies that can be loaded.

3.7.2 POLICY DESCRIPTION

1. Custom Policy

The power consumption management function that you can use to set corresponding power consumption control value according to the power

consumption distribution rule of the device at different time points. The system provides power consumption management function of time dimension

(the granularity is 1 hour), you can set different power capping value according to occupied/available periods of the device. After enabling such policy,

the power consumption value of the device or device group during a corresponding period of time will be controlled below the power capping. You can

set the floating ratio of the baseline according to the data accumulated during learning stage, or set the power consumption control value at each time

point in hours.

2. Database Policy

If the managed device has database related application, it is recommended to use database energy saving plan. This energy saving policy is

customized according to database scenario. The device will dynamically adjust power consumption according to the performance of database

application after policy configuration, therefore achieves maximum energy saving without affecting the service. For example, if the execution time of a

SQL in database is about 20 ms, it indicates that the database performance is normal, so the threshold of the response time can be set to 18 ms. If the

execution time of a SQL is less than 18 ms, the power consumption control will be performed and it will stop when the execution time is close to 18 ms.

When enabling this policy, all other policies which are being enabled will be disabled.
