3.7 POWER CONSUMPTIO N CONTROL

The devices can apply energy saving policy when their status are automatically set to "Enable Policy" after completing learning stage, or when you

manually set the status to "Enable Policy", otherwise, the policy related interface will not appear.

Energy Saving Policy refers to the control policy which is used to reduce power consumption. You can use the policy pre-defined by the system or

create a new policy to apply it to the device (group), achieving the goal of power consumption control and energy saving.

This product saves the information power consumption control policy into the hardware of the servers by communication with the server devices. When

a server device is added/deleted from the server device, all power consumption control policies stored in the hardware of the server will be deleted.

Before the physical removal of the managed server device, it is recommended to clear the hardware of the server device that stores the information of

power consumption control policies; this can be accomplished through the product by deleting or disabling all energy saving policies on the server

device and enabling all energy saving policy on the group which the device belongs to.

3.7.1 MANAGEMENT POLICY

1. Default Policy

According to the characteristics of resource consumption in different applications, the system provides five types of default policies that can be used

for power consumption control of the device for the first; 5%, 10%, 15% energy saving, workday power consumption control policy and holiday power

consumption control policy. For each different application type, different default policies can be enabled, and subsequently create new energy saving

policy based on the actual energy saving status.

The application server that is mainly used for CPU calculation (e.g. Web server). Such application has higher CPU performance requirements and may

save less energy. We recommend to apply 5% of energy saving policy.

The application server that is mainly used for memory application, such application has lower CPU performance requirements than that of the first kind

of server. We recommend to apply 10% of energy saving policy.

The application server that is mainly used for disk I/O (e.g. database server), such application has the lowest CPU performance requirements,

therefore may save the most energy. We recommend to apply 15% of energy saving policy.

Workday power consumption control policy: power consumption control policy effective during the workdays from Monday through Friday with the

default energy saving goal of 10%. For the servers that mainly receive higher traffic over the weekend, and less traffic during the weekdays, it is

recommended to enable weekday energy saving policy.

Holiday power consumption control policy: power consumption control policy effective at Saturday and Sunday with the default energy saving goal of

10% For the servers that mainly receive higher traffic over the weekdays, and less traffic during the weekends, it is recommended to enable weekend

energy saving policy.

2. Adding a New Policy

A policy can be applied to a device or a device group. Where: A device can share the policies of its device group, however, the device policies under

different groups can't be shared. Select the planned type that you need to add and fill in the related parameters to complete the addition of policy.

3. Priority of Policy

You can select the corresponding priority for each policy:

The energy saving policies that conflict with one another will be loaded by priority. Policies with higher priority will be loaded first.

For the policies that conflict with one another but have the same priority, the policy that has smaller energy saving control value will be loaded first.

4. Editing/Deleting a Policy

Select a policy to perform modification and deletion action.

5. Enabling/Disabling a Policy

Select a required policy, click the "Enable" button to apply the corresponding policy to the device (group).

Select a required policy, click the "Disable" button to remove the corresponding policy from the device (group).

If the device group has already activated a policy, all policies of all devices themselves within the group will be deactivated. The system will adjust the

power consumption control policy of the device group based on the energy saving policy of the device group.
