Server cabinet administration module 50 configurations become electric power power consumption number DC1 to DC12 are added up, and obtain power consumption number Ptotal that the current total electricity of centralized power module 40 consumes (wherein,
).
On the other hand, server cabinet administration module 50 configurations become to set an electric power power consumption target value PTG, and wherein, 50 expectations of server cabinet administration module are controlled at electric power power consumption target value PTG with the total electricity output power consumption number of centralized power module 40.
Server cabinet administration module 50 is electrically coupled to server 21 to 29 via System Management Bus (System Management bus, SM bus) SM_bus.And server cabinet administration module 50 is sent to server 21 to 29 via SM_bus with power consumption number Ptotal and the electric power power consumption target value PTG of the current total electricity consumption of centralized power module 40.
After each of server 21 to 29 is received the power consumption number Ptotal and electric power power consumption target value PTG that the current total electricity of centralized power module 40 consumes, to according to this electric power power consumption separately be controlled, so that the total electricity of centralized power module 40 output power consumption number can meet electric power power consumption target value PTG, detailed as hereinafter.
Figure 4 shows that in one embodiment of the invention the control signal transfer path synoptic diagram of the electric power power consumption information transfer path between server cabinet administration module 50 and the server 21 to 29 and server 21 to 29 inside.
Each of server 21 to 29 can comprise a micro-control unit (Micro Control Unit, MCU) and a plurality of CPU (central processing unit) (Central Processing Unit, CPU).For example, server 21 can comprise a micro-control unit M1 and two CPU (central processing unit) C1a and C1b.By that analogy, and server 29 can comprise a micro-control unit M9 and two CPU (central processing unit) C9a and C9b.
Power consumption number Ptotal and electric power power consumption target value PTG that the current total electricity of the centralized power module 40 that each the configurable one-tenth reception server of micro-control unit M1 to M9 rack administration module 50 of server 21 to 29 transmits consumes, and both are analyzed comparison.
If the power consumption number Ptotal that the current total electricity of centralized power module 40 consumes is greater than electric power power consumption target value PTG, then micro-control unit M1 to M9 configuration becomes to control for the electric power power consumption of server 21 to 29 respectively, to reduce the electric power power consumption of server 21 to 29; It can be so that the total electricity of centralized power module 40 output power-dissipation-reduced, and can meet electric power power consumption target value PTG.The embodiment that reduces the electric power power consumption of server 21 to 29 is to make the CPU (central processing unit) frequency reducing of server 21 to 29.
For example, for server 21, micro-control unit M1 configuration composition supplementary biography send control signal W1a and W1b to CPU (central processing unit) C1a and C1b, makes the current potential of " processor overheated (processor_hot, PROCHOT) " pin of CPU (central processing unit) C1a and C1b be in logic low potential.Therefore, the frequency of operation of CPU (central processing unit) C1a and C1b can reduce, to reduce the electric power power consumption of CPU (central processing unit) C1a and C1b; And the whole electric power power consumption of server 21 also with reduction.
By that analogy, the electric power power consumption control mode of server 22 to 29 also is same as the electric power power consumption control mode of server 21.For example, the micro-control unit M9 configuration composition supplementary biography of server 29 send control signal W9a and W9b to CPU (central processing unit) C9a and C9b, make the current potential of " processor overheated (processor_hot; PROCHOT) " pin of CPU (central processing unit) C9a and C9b be in logic low potential, with the frequency of operation that reduces CPU (central processing unit) C9a and C9b and and then reduce the electric power power consumption of CPU (central processing unit) C9a and C9b so that the whole electric power power-dissipation-reduced of server 29.
Figure 5 shows that in one embodiment of the invention the process flow diagram of the control method of the centralized power module 40 of server cabinet 10.
In step 501, server cabinet administration module 50 configurations become setting one to be associated with the electric power power consumption target value PTG of centralized power module 40.
Next, in step 502, server cabinet administration module 50 configurations become monitoring and receive the electric power power consumption information that is associated with each power supply unit 401 to 412 in the centralized power module 40.Wherein, be associated with power supply unit 401 to 412 electric power power consumption information DCT} comprise the direct current power output DC1 to DC12 of power supply unit 401 to 412 electric power power consumption number DC1 to DC12 (in other words, and DCT}={DC1, DC2 ..., DC12}).
Next, in step 503, server cabinet administration module 50 configurations become the electric power power consumption number DC1 to DC12 with power supply unit 401 to 412 to add up, and obtain power consumption number Ptotal that the current total electricity of centralized power module 40 consumes (wherein,
)。
Next, in step 504, the power consumption number Ptotal of the current total electricity consumption of the electric power power consumption target value PTG that is associated with centralized power module 40 that server cabinet administration module 50 configurations become will set and the centralized power module 40 that calculates is sent to each server 21 to 29.Each configuration of the micro-control unit M1 to M9 that arranges on the server 21 to 29 becomes to receive the power consumption number Ptotal of the current total electricity consumption of electric power power consumption target value PTG and centralized power module 40.
Next, in step 505, each configuration of micro-control unit M1 to M9 is paired in the power consumption number Ptotal of current total electricity consumption of centralized power module 40 and the electric power power consumption target value PTG of centralized power module 40 compares.
If the power consumption number Ptotal that the current total electricity of centralized power module 40 consumes then holds and carry out step 506 greater than electric power power consumption target value PTG.In step 506, reduce the electric power power consumption of the server 21 to 29 of controlling.Particularly, micro-control unit M1 to M9 configuration becomes to reduce respectively the electric power power consumption of server 21 to 29, and then can reduce the total electricity output power consumption number of centralized power module 40, make the total electricity output power consumption number of centralized power module 40 can meet electric power power consumption target value PTG.In present embodiment, the electric power power consumption of each server 21 to 29 is reduced to has identical electric power power consumption number.The embodiment that reduces the electric power power consumption of server 21 to 29 is: will be arranged at CPU (central processing unit) C1a, C1b on the server 21 to 29, each the potential setting of " processor is overheated " pin to C9a, C9b is logic low potential, make CPU (central processing unit) C1a, C1b,, each of C9a, C9b reduces frequency of operation.
Otherwise, if the power consumption number Ptotal of the current total electricity consumption of centralized power module 40 is less than or equal to electric power power consumption target value PTG, then need not the electric power power consumption of server 21 to 29 is adjusted.On the other hand, and repeatedly execution in step 502 is to step 504.
In sum, control device and the control method of the centralized power module of server cabinet of the present invention, to utilize the centralized power module a plurality of servers that are arranged in the server cabinet are carried out centralized management, not only can reduce the manufacturing cost of equipment, but also reduced the electric power energy that the equipment operation consumes, work efficiency is provided, has also improved equipment performance simultaneously.
