Below lift again an example, with the distribution running of bright first, second remaining power supply in more detail, please get back to Fig. 1.For convenience of description, suppose that Fig. 1 only has 4 motherboards (that is N=4), motherboard 151,152,153,15z are all the state that is activated, average power through distributing is 250KW, that is the power that power supply module 110 exports motherboard 151,152,153,15z in the starting stage is all 250KW.
At this moment, control module 122 can check the expectation power of each motherboard that is activated, so control module 122 reads the expectation power of motherboard 151,152,153,15z to the storer 124 or 126.The expectation power of supposing each motherboard is as follows: motherboard 151 is 200KW, and motherboard 152 is 200KW, and motherboard 153 is 300KW, and motherboard 15z is 250KW.Control module 122 is when checking, if the expectation power of motherboard itself can be defined as the first state greater than average power, if the expectation power of motherboard itself can be defined as the second state less than average power, if and expectation power is when just equaling average power, definition status not.So the expectation power 300KW of motherboard 153 is defined as the first state greater than average power 250KW; Motherboard 151,152 expectation power 200KW are defined as the second state less than average power 250KW.The expectation power of motherboard 15z just equals average power, does not belong to above-mentioned two states, does not therefore define any state.
On the other hand, for the ease of power distribution, control module 122 can be respectively with to the motherboard that is defined as the first state with the first logic level (for example, the logic high levle) represent, and will the motherboard that be defined as the second state be represented with the second logic level (for example, logic low level) respectively.Wherein, also can be opposite about the setting means of logic level, in this restriction especially.
Then, control module 122 is carried out dynamically remaining power supply reallocation for the first time, and with the first remaining power supply mean allocation to the motherboard 153 that is defined as the first state.The first remaining power supply is to surpass the power supply summation of expectation power in the motherboard 151,152 of second state that is defined as.Wherein, the first remaining power supply can be expressed as follows:
Because the motherboard of the first state only has one, therefore, overabsorption is to 100KW again for motherboard 153, that is present motherboard 153 is assigned to 350KW.Wherein, supply with 50KW at the motherboard 151 and 152 in this stage because distinctly being reduced, so be assigned to 200KW, motherboard 15z maintains 250KW.That is, supply this moment motherboard 151,152,153 and the power of 15z be respectively 200KW, 200KW, 350KW and 250KW.Note that the present invention is not limited to above-mentioned embodiment, for example when the motherboard of the first state has y, with the first remaining power supply divided by y, then carry out power distribution.
Thus, under the base case of identical power supply module 110, carry out remaining power supply reallocation mode and can guarantee the reliability of power supply compared with the fix power allocation mode of static state.And power distribution is also more efficient, and can reach energy-conservation.
In addition, can be again power distribution further, reach better equilibrium state so that be assigned to the power supply of motherboard, and the mode of carrying out is as follows: control module 122 can check whether the supply power of the motherboard 153 through being dispensed to the first state has satisfied the expectation power of itself.If the power of motherboard 153 through distributing has the expectation power that exceeds itself to be defined as the third state.The power that is assigned to due to motherboard 153 is 350KW, and for surpassing original expectation power 300KW of motherboard 153, result of determination is the third state to control module 122 according to the numerical value that distributes.Therefore, control module 122 calculates remaining power supply for the second time, and is still extremely the motherboard of the first state with the second remaining power supply mean allocation.Due to, without the motherboard of the first state, finish the power distribution flow process in illustrated embodiment.
Wherein, the second remaining power supply can be expressed as follows:
The motherboard of the second remaining power supply=(350KW-300KW)
153=50KW.
Wherein, as be familiar with this skill person and can know easily, control module 122 can reassign to the second remaining power supply motherboard 151 and 152 or no longer carry out power distribution again, the demand when its end is seen design and deciding.
Based on above-mentioned, it is whole as following table that the dynamic power supplies of the server system 100 of the present embodiment distributes situation to converge, and please refer to table 1.
Table 1
Moreover the power (power consumption control limits value) that is supplied to about each motherboard and the state that is defined can be recorded in storer 124 or storer 126.If the load of motherboard changes, control module 122 can recomputate and carry out power distribution, that is accomplishes instant power distribution for the demand of each motherboard.Similarly, if the open state of motherboard or load condition do not change, control module 122 makes power supply module 110 continue the power consumption control limits value and supplies the electric energy of respective members.
In addition, server system 100 is when again starting shooting, and control module 122 can be carried out power distribution rapidly according to each power consumption control limits value that storer 124 or 126 records.Therefore, the solution of the present embodiment is taken into account operational effectiveness when can or set energy SC service ceiling in restriction.
In sum, the central management bus of the embodiment of the present invention is according to the demand of each motherboard, takes reasonably and power distribution mechanism dynamically, so can effectively solve the power supply reliability problem of tradition because adopting the fix power allocation mode to be derived.Thus, can make each member and the motherboard all can normal operation, and give full play to the operational effectiveness of total system.On the other hand, it is energy-conservation that the power distribution of the method can reach, and can effectively reduce equipment cost.
