In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The present invention provides a kind of server system power supply equalization methods, are applied to power supply unit, shown in Figure 1,
This method comprises:
Step s1: the current value in the server system sensed in itself current-sensing circuit is obtained, and obtains clothes
The current power consumption setting value of device system of being engaged in；
It is understood that being provided with current-sensing circuit in power supply unit, which can obtain electricity
Flow valuve, and the current value in server system can increase as the number of the current-sensing circuit of power supply increases.Therefore, pass through
The current value in server system is obtained, that is, may determine therefrom that the number for the current supply currently powered.Also, server system
The power consumption setting value for uniting current refers to that the power consumption initial value of the current sets itself of system, the initial value can characterize server
The power consumption demand of system.In addition, the mode generallyd use is when power supply unit obtains the power consumption setting value of server system
It is obtained by I2C bus connection server, because I2C bus protocol is able to carry out the acquisition of characteristic, Neng Goutong
I2C bus is crossed to carry out the reading of power consumption setting value.Certainly, server system can also be obtained using other modes in practical application
The power consumption setting value for uniting current, this is not limited by the present invention.
Step s2: the size according to current value determines the number for the power supply unit currently powered in server system；
Step s3: according to the number for the power supply unit currently powered in server system, above-mentioned power consumption setting value and
Default allotment rule, judges itself whether need to stop powering under present case, treats coldly machine shape if so, controlling itself and entering
State is powered if it is not, controlling itself；Default allotment rule will deploy result and meet the power consumption demand of server system as the
One constraint condition.
It, can be according to the power consumption demand of server system (i.e. after determining the number for the power supply unit currently powered
Power consumption setting value) come the number for the power supply unit for selecting needs increase power supply or reduction to power.According to default allotment rule
Whether control specifically controlling each power supply unit and itself is powered or controls itself into cool standby state.Wherein,
It is the number of the power supply unit by adjusting power supply to realize the power consumption of adjustment server system due to the purpose of the present invention
, it is thus possible to it needs to increase the number of the power supply unit of power supply or reduces the number of the power supply unit of power supply.Therefore,
In order to realize the purpose, except when preceding in running order power supply unit is able to carry out outside the above method, in treating coldly machine
The power supply unit of state be also required to be able to carry out aforesaid operations, to choose whether the state of restoring electricity that draws oneself up.
The present invention provides a kind of server system power supply equalization methods, obtain what it was sensed by current-sensing circuit
The current value of server system, and the power consumption setting value of server system is obtained, server is determined according to the size of current value
The number for the power supply unit currently powered in system, later according to for the power supply unit currently powered in server system
Number, power consumption setting value and default allotment rule, carry out selective control itself and enter cool standby state or be powered.It can
See, power supply unit being capable of current value in the server system that arrives of direct basis autonomous induction and server system in the present invention
The power consumption demand of system, to adjust whether itself enters power supply state, to realize that the power supply being powered in server system supplies
The allotment of power supply unit is completed in the adjustment for answering the number of device, improves the power supply ability of equalization of server system.
Preferably, presetting allotment rule also makes a of the power supply unit powered in server system for allotment result
Number is at least used as the second constraint condition.
It is understood that in the case where meeting the power consumption demand of server system, of the power supply unit of power supply
Number is fewer, then the energy consumption of entire server system is fewer.Therefore, the electricity powered in server system will be guaranteed by presetting allotment rule
The number of source power supply unit is at least used as the second constraint condition.I.e. so that finally allotment result is to meet server system power consumption need
The number for the power supply unit powered in the case where asking is minimum, to realize energy-efficient purpose.
In other embodiments, since power supply unit may adjust itself according to the demand of current server system
Power consumption is exported, so that the output power consumption of current each power supply unit is different.In this case there may be meeting clothes
When device system power dissipation demand of being engaged in, the power supply unit number of power supply and the minimum for not up to presetting allotment specified by rules originally
Value.For example, it is assumed that current powering there are five power supply unit, it is desirable to reduce to three, but due to one of power supply
Power supply unit output power consumption is larger, and therefore, after the power supply unit stops powering, the power consumption of server system has met need
It asks, if not limiting above-mentioned second constraint condition in this case, the power supply unit powered at this time remains in four, and
The minimum value according to default allotment specified by rules is not reached.Certainly, if the second constraint condition of setting can be according to itself
Depending on demand, the application does not limit this.
Preferably, pass through a resistance connection, resistance and power supply between each power supply unit and server respectively
Power supply unit is arranged in a one-to-one correspondence；In parallel each other, group of establishing the corresponding resistance of each power supply unit of connection with server
At resistor coupled in parallel circuit；What current-sensing circuit incuded is the electric current in resistor coupled in parallel circuit.Referring to fig. 4 and shown in Fig. 5.
It is understood that in the present embodiment, obtaining the electric current in server system in order to facilitate power source sensing circuit
Determining the number for the power supply unit currently powered, the present embodiment is that each power supply unit is provided with a corresponding resistance,
After establishing connection between power supply unit and server, the output end of the resistance one end and power supply unit is connected, the other end
Server is connected, and for each power supply unit for establishing connection between server, resistance is formed simultaneously each other
Connection.As an example it is assumed that the corresponding resistance of power supply unit A is resistance 1, the corresponding resistance of power supply unit B is resistance 2, when
It after power supply unit A and B establish connection with server, then will form parallel connection between resistance 1 and resistance 2, form resistor coupled in parallel
Circuit.It is understood that overall electrical resistance resistance value in parallel is lower, and each power supply unit is defeated when resistance in parallel is more
Enter bigger to the electric current in resistor coupled in parallel circuit.Therefore, according to the current conditions in resistor coupled in parallel circuit, that is, can determine currently has
Several resistor coupled in parallel so that it is determined that currently there is several power supply unit connection servers, and are powered for it.Therefore according to above-mentioned electricity
That current value of resistance parallel circuit can intuitively determine the number of the power supply unit of power supply in current server system.
Further, the corresponding resistance of each power supply unit is identical；Current-sensing circuit is used for inductive reactance simultaneously
Join single ohmically current value in circuit.
It is understood that overall electrical resistance is smaller when resistor coupled in parallel number is more, therefore each power supply unit exports
Electric current it is bigger, in this case, not only in resistor coupled in parallel circuit total current increase.It is single ohmically in resistor coupled in parallel circuit
Electric current is also bigger.For example, the corresponding resistance of each power supply unit is R, only has an electricity in resistor coupled in parallel circuit
When resistance, electric current is I on resistance, when there are two resistor coupled in parallel, the electric current point of the corresponding power supply unit output of two resistance
Not Wei I1 and I2, therefore, the electric current flowed through on each resistance be (I1+I2)/2, since I1 and I2 are all larger than I, (I1+
I2)/2 also greater than I, so when each resistance on the electric current that flows through compared to an only resistance Shi Yao great.Therefore, simultaneously by resistance
Join that single ohmically electric current of circuit, it can determine the number of the power supply unit of power supply.And the present embodiment restriction is each
The corresponding resistance of power supply unit is identical, is calculated and is powered for convenience after obtain ohmically electric current
The number of power supply unit.Certainly, in other embodiments, after obtaining electric current., can not be calculated by formula and determine power supply
Power supply unit number, but table is directly saved in each power supply unit, record has each current value in table
The number of corresponding power supply unit, specifically without limitation using which kind of mode present invention.
In addition, in other embodiments, when the corresponding resistance of each power supply unit is identical, current-sensing circuit
Also the electric current that available resistor coupled in parallel circuit always exports, and determine therefrom that the number of the power supply unit of power supply.
Due to above each embodiment, the number for the power supply unit currently powered only can determine, it is true without method
Which the power supply unit powered before settled is, therefore, can identify the power supply currently powered according to current value to realize
The label of power supply unit, the present invention provides following embodiments:
In this embodiment, the corresponding resistance of each power supply unit is different；Current-sensing circuit induction
It is total output electric current of resistor coupled in parallel circuit.
Correspondingly, the size according to the current value determines the power supply supply currently powered in the server system
The process of the number of device are as follows: be grouped corresponding table according to the size of the current value and preset electric current, determine the current value
Corresponding power supply unit grouping, the number and its label of the power supply unit currently powered.
It is understood that the purpose of the invention is to expire by adjusting the number of the power supply unit currently powered
The power consumption demand of sufficient server system.And the present invention is applied in each power supply unit, therefore in order to avoid needing
When the number adjustment for the power supply unit being powered, each power supply unit selects to change oneself state, leads to not full
The case where power consumption demand of sufficient server system, occurs.The present invention is required to guarantee according to prediction allotment rule every time only
A several power supply units are needed to adjust the state of oneself.As an example it is assumed that current, there are five the power supply units powered, still
Three are only needed to be powered, it is therefore desirable to which two power supply units enter cool standby state, in this case, due to each electricity
Source power supply unit can learn the demand, it is therefore desirable to avoid exceeding two power supply units and control and itself enter standby shape
The case where state.
It in an advantageous embodiment, can be by pre-saving the priority of each power supply unit in power supply unit
Different resistances is arranged in sequence and different power supply units, to enable power supply unit to learn current power supply
Power supply unit label, come realize every time only needed for several power supply units adjust oneself state purpose.This
In kind method, the current value for being first depending on server system determines the number and its label for the power supply unit currently powered, and
The number of the current power supply unit for needing to increase power supply or reducing power supply is learnt, later according to the power supply supply currently powered
The label of device determines its priority, and the priority of power supply unit locating for determination itself and the power supply unit that do not power
Priority.Judge itself whether need to stop powering or be powered according to above- mentioned information later.As an example it is assumed that
Currently needs to increase by two power supply units and be powered, and the power supply unit locating for itself be in cool standby state and preferentially
Rank is highest, then self-recovery is powered at this time.Certainly, in this kind of method, in fact it could happen that priority level height should restore to supply
The power supply unit of electricity, the case where can not being powered due to not plug in power supply line, such case will lead to this time adjustment and complete
Afterwards, it is unable to satisfy the adjustment demand of script, therefore, can continue to be adjusted when number next time adjusts.In addition, in order to the greatest extent
After the completion of may avoiding the occurrence of adjustment.The excessive or very few situation of the number of the power supply unit of power supply, can enable each power supply
Power supply unit has different priority.
In another embodiment, in order to realize every time only needed for several power supply units adjust oneself state mesh
, following manner also can be used, shown in Figure 2, i.e. the process of step s3 includes:
Step s31: according to the number for the power supply unit currently powered in server system, above-mentioned power consumption setting value and
Default allotment rule determines the number of the current power supply unit for needing to stop power supply or increasing power supply；
Step s32: currently itself whether need to adjust power supply state according to default allotment rule judgement, if desired adjustment supplies
Electricity condition then enters step s33；If not needing adjustment power supply state, itself current power supply state is kept.
Step s33: reacquiring the current value in the server system sensed in itself current-sensing circuit, according to weight
Whether the current value that newly obtains and default allotment rule determination currently itself need to stop powering, if so, control itself into
Enter cool standby state, is powered if it is not, controlling itself.
It is understood that each power supply unit can have temporal error, make in this way when obtaining current value
, whether each power supply unit is all different determining itself to need to adjust state for time.For example, if being currently both needed to
The power supply unit of a power supply is reduced, in this case when power supply unit A determines itself to need to enter cool standby state
When, power supply unit B may come into cool standby state at this time, therefore power supply unit A is no longer needed to adjust itself shape
State.The present invention in order to avoid time more backward power supply unit is in the adjustment situation for not learning other Power Supplier,
Having carried out the state adjustment of itself causes the number of the power supply unit of finally obtained power supply not meet demand, therefore every
When a power supply unit judges that itself needs to adjust power supply state, once whether have by current current value determination first
The power supply unit of fast speed completes adjustment.And itself no longer to need to adjust state.If according to current current value
The number adjustment for determining the power supply unit that the power consumption demand for being still not up to server needs to be powered, then adjust certainly again at this time
The power supply state of body.After the completion of this mode can guarantee once adjustment as far as possible, the number energy of the power supply unit of power supply
Enough meet the power consumption demand of server.In addition, when reacquiring the current value in server system, due to server system at this time
The power consumption demand of system is usual and has not been changed, therefore can no longer obtain the power consumption setting value of server system at this time, but foundation
The preceding power consumption setting value once obtained is judged；Certainly, in other embodiments, the also power consumption of available server system
Setting value, this is not limited by the present invention.
In another preferred embodiment, to achieve the goals above, itself can be previously provided in power supply device
Corresponding delay time, each power supply unit corresponding delay time are different；According to default allotment rule judgement it is current itself
It is shown in Figure 3 after needing to adjust power supply state, then before entering step s33, further includes:
Step s330: the delay time according to itself setting is waited, and after waiting for, enters back into step s33.
It is understood that due to the time error between different electrical power power supply unit may very little, in this case,
When the power supply unit of front one starts to adjust oneself state but not yet adjustment is completed, the latter power supply unit may also judge
It oneself needs to adjust state, in this case, due to judging according to the electric current in current server system it can be seen that not meeting
Actual power consumption demand, therefore, the latter power supply unit may also start to adjust the state of oneself, so that adjustment state
Power supply unit number it is excessive, cause final result to be unsatisfactory for demand.Therefore, in order to avoid the situation, compared to randomness compared with
Strong time error, the present embodiment are that each power supply unit is provided with different delay times, when judgement itself needs to adjust
When power supply state, after waiting the delay time of oneself to reach first, then current current value is detected, determines whether to meet clothes
The power supply power consumption demand of business device itself no longer needs to be adjusted if having met, if not satisfied, itself adjusts power supply again
State.As an example it is assumed that the current power supply unit for only needing to increase a power supply, the delay time of power supply unit A are
5s, then when power supply unit A determines itself to need to wait the time of 5s first, later from when treating coldly machine and being adjusted to power supply state
Determination currently itself also needs not needing carry out state adjustment again, if delay time has turned to less than the power supply unit of oneself
The number of power supply state, the then power supply unit powered in server system at this time has met, therefore then power supply unit A is not
It needs to adjust again.Therefore, this mode of the present embodiment, the number of the power supply unit of the power supply after substantially avoided final adjustment
The case where not meeting demand appearance ensure that server system actual power can satisfy oneself power consumption demand.
In addition, in order to avoid certain power supply units for occurring powering in special circumstances during the adjustment fully enter it is cold
It is standby, and appearance the case where cause server system that can not work.In a preferred embodiment, it can set one in server system
The state of a power supply unit is to power always.I.e. in any case, which is in power supply state always, without
Into treating coldly machine.To ensure that under any circumstance, server system can have power supply as far as possible.
Certainly, the above is only several specific embodiments.The present invention does not limit the particular content of default adjustment rule.
Preferably, this method further include:
According to the size and default balanced rule of current value, the output power consumption of control adjustment itself.
It is understood that adjusting the power supply of power supply unit in the actual demand according to server system, making it possible to
The power saving as far as possible in the case where meeting the power consumption demand of server system.In this case, in addition to the power supply of adjustment power supply supplies
The number of device is answered, power supply unit output power consumption can also be adjusted, to realize the supply of server system interior power from many aspects
The balanced output of device and purpose as energy-efficient as possible.For example, reduction can be passed through when the power consumption needed for server system is not high
The number of the power supply unit of power supply can also realize the mesh of power saving by the power consumption of the power supply unit of each power supply of reduction
's.And the power supply capacity that can also adjust each power supply unit in the application makes power supply unit mean allocation output work
Consumption, achievees the purpose that power saving.
It is shown in Figure 6 the present invention also provides a kind of power supply unit, comprising:
Current detecting unit 1, for obtaining the current value in the server system sensed in itself current-sensing circuit,
And obtain the current power consumption setting value of the server system；
Balanced unit 2 is exported, determines the power supply currently powered in server system supply for the size according to current value
The number of device；According to the number for the power supply unit currently powered in server system, power consumption setting value and default allotment rule
Then, judge itself whether need to stop powering under present case, if so, controlling itself into cool standby state, if it is not, control
Itself is powered；The first of the regular power consumption demand for meeting the server system comprising allotment result of default allotment is about
Beam condition.
It is apparent to those skilled in the art that for convenience and simplicity of description, the unit of foregoing description
Specific work process, can refer to corresponding processes in the foregoing method embodiment, details are not described herein.
The present invention also provides a kind of server system, including server and several power supply units, power supply supplies
