DC1 to DC12 and AC power inputs AC1 to AC12 are monitored and receive monitored power consumption information.

The power consumption information (ie, power consumption value) associated with the DC power outputs DC1 to DC12 of the power supply units 401 to 412 can be expressed as {DC _T }, where {DC _T }={DC ₁ , DC ₂ ,.. ..,DC ₁₂ }.

On the other hand, the server rack management module 50 is configured to set a power consumption target value P _TG , wherein the server rack management module 50 desires to control the total power output power consumption value of the centralized power module 40 at Power consumption target value P _TG .

The server cabinet management module 50 is electrically coupled to the servers 21 to 29 via a system management bus (SM bus) SM_bus. The server rack management module 50 transmits the current total power consumption power consumption value P _total and the power power consumption target value P _{TG of the} centralized power module 40 to the servers 21 to 29 via SM_bus.

Each of the servers 21 to 29 receives the power consumption value P _total and the power consumption target value P _TG of the current total power consumption of the centralized power module 40, and then controls the respective power consumption. So that the total power output power consumption value of the centralized power module 40 can meet the power consumption target value P _TG , as described below.

Each of the servers 21 to 29 may include a Micro Control Unit (MCU) and a plurality of Central Processing Units (CPUs). For example, the server 21 may include a micro control unit M1 and two central processing units C1a and C1b. By analogy, the server 29 can include a micro control unit M9 and two central processing units C9a and C9b.

The server 21-29 of each of the micro control unit M1 to M9 may be configured to receive server rack management module 50 transmits the centralized power module 40 of the present value of the total power P _total and power consumption of reactive power The target value P _{TG is} consumed and the two are analyzed and compared.

If the current total power consumption power consumption value P _{total of the} centralized power module 40 is greater than the power consumption target value P _TG , the micro control units M1 to M9 are configured to control the power consumption of the servers 21 to 29, respectively. In order to reduce the power consumption of the servers 21 to 29; it can reduce the total power output power consumption of the centralized power module 40, and can meet the power consumption target value P _TG . An embodiment of reducing the power consumption of the servers 21 to 29 is to down-clock the central processing units of the servers 21 to 29.

For example, for the server 21, the micro control unit M1 is configured to transmit the control signals W _1a and W _1b to the central processing units C1a and C1b, respectively, so that the processor of the central processing units C1a and C1b is overheated (processor_hot, PROCHOT). The pin potential is at a logic low. Therefore, the operating frequencies of the central processing units C1a and C1b can be reduced to reduce the power consumption of the central processing units C1a and C1b; and the overall power consumption of the server 21 is also reduced.

By analogy, the power consumption control modes of the servers 22 to 29 are also the same as the power consumption control mode of the server 21. For example, the micro control unit M9 of the server 29 is configured to transmit the control signals W _9a and W _9b to the central processing units C9a and C9b, respectively, so that the "processor_hot (PROCHOT)" pins of the central processing units C9a and C9b are connected. The potential is at a logic low to reduce the operating frequency of the central processing units C9a and C9b and thereby reduce the power consumption of the central processing units C9a and C9b to reduce the overall power consumption of the servo 29.

In step 501, the server rack management module 50 is configured to set a power consumption target value P _TG associated with the centralized power module 40.

Next, in step 502, the server rack management module 50 is configured to monitor and receive power consumption information associated with each of the power supply units 401 through 412 of the centralized power module 40. Wherein, the power consumption information {DC _T } associated with the power supply units 401 to 412 includes the power consumption values DC ₁ to DC ₁₂ of the DC power outputs DC1 to DC12 of the power supply units 401 to 412 (in other words, {DC _T } ={DC ₁ ,DC ₂ ,...,DC ₁₂ }).

Next, in step 503, the server rack management module 50 is configured to sum the power consumption values DC ₁ to DC _{12 of the} power supply units 401 to 412 to obtain the current total of the centralized power module 40. Power consumption value of power consumption P _total (where ).

Next, in step 504, the server rack management module 50 configured to associate the set of centralized power module to the target value of power consumption P _TG 40 and the calculated power module 40 of the centralized The current total power consumption power consumption value P _{total is} transmitted to each of the servers 21 to 29. Each of the micro control units M1 to M9 provided on the servers 21 to 29 is configured to receive the power consumption target value P _TG and the current total power consumption power consumption value P _{total of the} centralized power supply module 40.

Next, in step 505, the micro control unit M1 to M9, each of centralized power module configured as current consumption value of the total power consumption of 40 P _total centralized power consumption for the power module 40 of The target value P _TG is compared.

If the current total power consumption power consumption value P _{total of the} centralized power module 40 is greater than the power consumption target value P _TG , then step 506 is performed. In step 506, the power consumption of the controlled servers 21 to 29 is reduced. Specifically, the micro control units M1 to M9 are configured to reduce the power consumption of the servers 21 to 29, respectively, thereby reducing the total power output power consumption value of the centralized power module 40, so that the centralized power module 40 The total power output power consumption value can be in accordance with the power consumption target value P _TG . In the present embodiment, the power consumption of each of the servers 21 to 29 is reduced to have the same power consumption value. The implementation of reducing the power consumption of the servers 21 to 29 is to "processor overheating" each of the central processing units C1a, C1b, ..., to C9a, C9b provided on the servers 21 to 29. The potential of the pin is set to a logic low level to lower the operating frequency of each of the central processing units C1a, C1b, ..., C9a, C9b.

On the other hand, if the current total power consumption power consumption value P _{total of the} centralized power module 40 is less than or equal to the power consumption target value P _TG , the power consumption of the servers 21 to 29 need not be adjusted. On the other hand, step 502 to step 504 are repeatedly performed.
