Based on electric control system on above-mentioned hard disk shown in FIG. 1, the application provides a kind of hard disk electrification control method, refering to Fig. 5, Fig. 5 show the flow diagram of hard disk electrification control method provided by the embodiments of the present application.

Hard disk electrification control method provided by the embodiments of the present application includes:

Step 110: when detecting that power supply real-time current is less than quota electric current, obtaining power supply real-time current in preset duration Interior peak value.

Power supply real-time current is that power supply is supplied to all real-time currents for having powered on hard disk, wherein has powered on hard disk Including in the starting state hard disk and or have been started up the hard disk for completing to enter in normal operating conditions.Quota electric current is Power supply is supplied to the maximum current that all hard disks are able to use, and in other words, quota electric current refers to that power supply can be to hard Disk stablizes the net capability provided.The quota electric current of power supply can be pre-configured with, as that can choose default model Power supply, or the power supply capacity of power supply is allocated to determine quota electric current, such as provide power supply to total electricity 80% distribution of stream is to be powered hard disk, then the 80% of total current is quota electric current, if power supply is capable of providing 10A's Electric current supply, distributes to other devices such as mainboard for 20%, by 80% as the quota electric current powered to hard disk, then quota electric current For 8A.

Current detection circuit real-time detection obtain power supply real-time current, when detect power supply real-time current be less than quota electric current When, obtain peak value of the power supply real-time current in preset duration, it is possible to understand that ground, different model, the hard disk of state its consumption Electric current is also different, and generally, hard disk its electric current in start-up course may be the electricity of the hard disk in normal operating conditions 2~3 times of stream, therefore power supply real-time current is real-time change, the hard disk quantity in start-up course is more, then power supply is real When electric current it is bigger.Preset duration referred to the regular hour of current point in time forward trace, for example, forward with current point in time Backtracking 1 second or 2 seconds, i.e. preset duration can be 1 second or 2 seconds, but not limited to this, it can also be other time spans, have Body can be determined according to the starting duration of hard disk.By taking preset duration is 1 second as an example, when detecting that power supply real-time current is less than When quota electric current, peak value of the power supply real-time current in 1 second is obtained, is to obtain power supply real-time current within past 1 second most Big value.

Step 120: asking difference to obtain quota electric current according to the peak value of quota electric current and power supply real-time current in preset duration Surplus.

Quota electric current surplus refers to the difference of the peak value of quota electric current and power supply real-time current in preset duration, it is possible to understand that Ground, for the power supply of hard disk, quota electric current refers to that power supply is supplied to the maximum electricity that all hard disks are able to use Stream or power supply can stablize the net capability provided to hard disk, and power supply real-time current refers to that having powered on hard disk has disappeared The power supply capacity of consumption, quota electric current surplus then refer to the remaining power supply capacity of power supply, when there are quota electric currents for power supply When surplus, illustrate that power supply is not up to full load condition.

Step 130: the newly-increased target for powering on hard disk is determined according to quota electric current surplus and single hard disk maximum starting current Quantity.

Single hard disk maximum starting current refers to the maximum value of hard disk startup electric current, and different hard disks, starting current is different, Using the maximum value in the starting current of multiple hard disks as single hard disk maximum starting current.It is hard according to quota electric current surplus and list Disk maximum starting current determines the newly-increased destination number for powering on hard disk, for example, starting to quota electric current surplus and single hard disk maximum The ratio of electric current, which is rounded downwards, determines destination number, so that newly-increased the sum of the starting current of hard disk that powers on is less than or equal to quota electricity Flow surplus, it is ensured that newly-increased to power on electric current consumed by the starting of hard disk without departing from the remaining power supply capacity of power supply.

Step 140: being powered on according to destination number to not powering on hard disk.

According to determining destination number, hard disk is not powered on to destination number and is powered on, it is possible to understand that ground, it is newly-increased to power on hard disk The sum of starting current be less than or equal to quota electric current surplus.

Hard disk electrification control method provided by the embodiments of the present application, by obtaining power supply real-time current in preset duration Peak value asks difference to obtain quota electric current surplus according to the peak value of quota electric current and power supply real-time current in preset duration, can be true Determine the remaining load capacity of power supply, is then determined on newly-increased according to the maximum starting current of quota electric current surplus and single hard disk The destination number of electric hard disk determines the quantity of hard disk that power supply can also load according to the load capacity of power supply, Then control destination number does not power on hard disk electrifying startup.On the one hand in power supply, there are make more when additional load capacity The timely electrifying startup of more hard disks, can be improved power-efficient, on the other hand, determine according to single hard disk maximum starting current newly-increased Power on the destination number of hard disk, it is ensured that the newly-increased starting current for powering on hard disk does not exceed quota electric current surplus, Bu Huichao Power supply is supplied to the power supply capacity of hard disk out, and overcurrent, which will not occur, leads to situations such as triggering overcurrent protection or shutting down.

It is to be appreciated that power supply real-time current changes after not powering on hard disk electrifying startup, quota electric current surplus phase Also it can change with answering, so as to determine the new newly-increased destination number for powering on hard disk again, be carried out to hard disk is not powered on Electrifying startup is not until all powers on the equal start completion of hard disk.

For example, being illustrated by taking system architecture shown in FIG. 1 as an example, if the quota electric current of power supply is Imax, work as electricity When source real-time current is less than quota electric current Imax, peak I t of the power supply real-time current in 1 second is obtained, according to quota electric current Imax And peak I t of the power supply real-time current in 1 second determines quota electric current surplus Iremain.Wherein, quota electric current surplus Peak I t, the quota electric current Imax of Iremain, power supply real-time current in 1 second meet following formula:

Iremain=Imax-It.

After determining quota electric current surplus Iremain, electricity is started according to quota electric current surplus Iremain and single hard disk maximum Flow I_hddDetermine the newly-increased destination number N for powering on hard disk.Specifically, in this present embodiment, by quota electric current surplus Iremain with Single hard disk maximum starting current I_hddRatio be rounded downwards and be determined as the newly-increased destination number N for powering on hard disk.Quota electric current Surplus Iremain, single hard disk maximum starting current I_hdd, the newly-increased destination number N for powering on hard disk meet following formula:

N=[Iremain/I_hdd]。

Rounding, which refers to, downwards takes the maximum integer smaller than the data, if Iremain/I_hddValue be 5.2, then carry out downward The value of N is 5 after rounding, if Iremain/I_hddValue be 4.9, then after being rounded downwards the value of N be 4, due to single hard disk maximum Starting current is the maximum value in the starting current of multiple hard disks, therefore, N number of newly-increased to power on the sum of starting current of hard disk and be less than Or it is equal to quota electric current surplus Iremain, therefore the newly-increased hard disk that powers on will not cause volume except quota electric current to power supply Outer burden not will lead to power supply triggering overcurrent protection without departing from the power supply capacity to hard disk that power supply provides.

In one possible implementation, part hard disk uses multiple feed, the basis of method shown in Fig. 5 On, the embodiment of the present application provides another hard disk electrification control method, shows the embodiment of the present application refering to Fig. 6, Fig. 6 and provides Another hard disk electrification control method flow diagram.

When not powering on hard disk with multiple power supplies, step 130 includes following sub-step:

Step 130-1: electricity is started according to the corresponding quota electric current surplus of each power supply and single hard disk maximum respectively It flows and determines the corresponding newly-increased initial target quantity for powering on hard disk of each power supply.

When hard disk has multiple power supplies, for example, be illustrated by taking system architecture shown in Fig. 2 as an example, each Hard disk is powered simultaneously by the first power supply and second source, and correspondingly, each hard disk has corresponding switching circuit, switch electricity Road is used to control the first power supply and second source be supplied to the hard disk power supply on-off.

It is determined respectively according to the corresponding quota electric current surplus of each power supply and single hard disk maximum starting current first The corresponding newly-increased initial target quantity for powering on hard disk of each power supply.

First power supply and second source are independently powered hard disk, the corresponding first quota electric current of the first power supply, the One power supply real-time current, so that the first power supply is corresponding to have the first quota electric current surplus.Similarly, the second power supply corresponding second Quota electric current, second source real-time current and the second quota electric current surplus.

Each confession is determined according to the corresponding quota electric current surplus of each power supply and single hard disk maximum starting current The corresponding newly-increased initial target quantity for powering on hard disk of power supply, is to be opened according to the first quota electric current surplus and single hard disk maximum Streaming current determines the first initial target quantity that the first quota electric current surplus can load；In this present embodiment, by the first quota Electric current surplus and the ratio of single hard disk maximum starting current are rounded downwards, and it is initial as first will to be rounded treated result Destination number.Similarly, the second quota electric current surplus is determined also according to the second quota electric current surplus and single hard disk maximum starting current The the second initial target quantity that can be loaded.

Step 130-2: the minimum value in multiple initial target quantity is determined as destination number.

By taking hard disk has 2 power supplies as an example, the first power supply can one initial target quantity of load regulation be newly-increased powers on Hard disk, the second power supply can load regulation two initial target quantity be newly-increased powers on hard disk, but due in hard disk power up Powered simultaneously by multiple power supplies, in other words, in order to ensure each power supply does not trigger overcurrent protection, need by Minimum value in multiple initial target quantity is determined as destination number.In other words, it needs to meet all power supplies simultaneously Load capacity, prevent any one power supply occur overload, overcurrent situations such as.

Below with reference to system architecture shown in Fig. 2, to method stream shown in fig. 6 by taking hard disk has 2 power supplies as an example Journey is illustrated.

Hard disk has the first power supply (such as 5V power supply) and second source (such as 12V power supply).First power supply corresponds to the first quota Electric current Imax_5V, the corresponding second quota electric current Imax_12V of second source.

It is to be appreciated that different power supplies corresponds to different power supply real-time currents, it is real-time also to correspond to different power supplys Peak value of the electric current in preset duration.Such as, peak value of the corresponding first power supply real-time current of the first power supply in preset duration is It_5V, peak value of the corresponding second source real-time current of second source in preset duration are It_12V.According to each power supply Peak value in preset duration of quota electric current and power supply real-time current determine the quota electric current surplus of each power supply, In, preset duration can take 1 second.For example, the first power supply corresponds to the first quota electric current surplus Iremain_5V, second source is corresponding Second quota electric current surplus Iremain_12V, then for the first quota electric current surplus Iremain_5V, the first power supply real-time current Peak I t_5V, the first quota electric current Imax_5V in preset duration meet following formula:

Iremain_5V=Imax_5V-It_5V.

Similarly, for the second quota electric current surplus Iremain_12V, peak of the second source real-time current in preset duration Value It_12V, the second quota electric current Imax_12V meet following formula:

Iremain_12V=Imax_12V-It_12V.

The relatively different power supply of hard disk has different single hard disk maximum starting currents, such as corresponding first electricity of hard disk The single hard disk maximum starting current in source is I_hdd_ 5V, the single hard disk maximum starting current that hard disk corresponds to second source is I_hdd_ 12V, Each power supply electricity is determined according to the corresponding quota electric current surplus of each power supply and single hard disk maximum starting current respectively The corresponding newly-increased initial target quantity for powering on hard disk in source.

The first initial target quantity N1 is determined according to the first quota electric current surplus Iremain_5V.For example, to the first quota The single hard disk maximum starting current I of electric current surplus Iremain_5V the first power supply corresponding with hard disk_hddThe quotient of _ 5V is rounded downwards really Fixed first initial target quantity N1, then the single hard disk maximum of the first initial target quantity N1 and corresponding first power supply of hard disk starts electricity Flow I_hdd_ 5V meets following formula:

N1=[Iremain_5V/I_hdd_5V]。

Similarly, the second initial target quantity N2 is determined according to the second quota electric current surplus Iremain_12V.Second initial mesh The single hard disk maximum starting current that mark quantity N2 and hard disk correspond to second source is I_hdd_ 12V meets following formula:

N2=[Iremain_12V/I_hdd_12V]。

It is to be appreciated that the first initial target quantity N1 is the newly-increased initial mesh for powering on hard disk that the first power supply can load Quantity is marked, the second initial target quantity N2 is the newly-increased initial target quantity for powering on hard disk that can load of second source, by the Minimum value in one initial target quantity N1 and the second initial target quantity N2 is determined as destination number N, to ensure all confessions The case where power supply all works in safe range, is not in overcurrent.

For example, if the first initial target quantity N1 is 5, and the second initial target quantity N2 is 7, then it is initial by first Destination number N1 is determined as destination number N.It is to be appreciated that initial target quantity is smaller, illustrate the negative of corresponding power supply Loading capability is lower, using the minimum value in multiple initial target quantity as the newly-increased destination number for powering on hard disk, can guarantee most The normal work of the power supply of low-load ability, without departing from its load capacity or power supply capacity, then all power supplies Situations such as being not in overcurrent or overload.

Hard disk electrification control method provided by the embodiments of the present application, when hard disk has multiple power supplies, according to each A power supply determines the newly-increased initial target quantity for powering on hard disk, then using the minimum value in multiple initial target quantity as The newly-increased destination number for powering on hard disk powers on the initial of hard disk according to determining increase newly of the quota electric current surplus of each power supply Destination number, and take its minimum value as the newly-increased destination number for powering on hard disk, it is ensured that multiple power supplies can be safe Power supply, will not trigger overcurrent protection.

The electric current that hard disk is under normal operating conditions is generally less than the electric current that hard disk is in start-up course, with hard disk Electrifying startup is completed, it is possible to understand that ground, the quantity for not powering on hard disk can gradually reduce, until all hard disks are completed to power on to open It is dynamic.On the basis of Fig. 6, refering to Fig. 7, the embodiment of the present application has also mentioned another hardware electrification control method.

Wherein, step 140 includes following sub-step:

Step 140-1: whether confirmation destination number is less than the quantity for not powering on hard disk.

Destination number is compared with the quantity for not powering on hard disk, whether confirmation destination number, which is less than, does not power on hard disk Quantity executes step 140-2 when destination number is less than the quantity for not powering on hard disk, when destination number is greater than or equal on not When the quantity of electric hard disk, step 140-3 is executed.

Step 140-2: when destination number is less than the quantity for not powering on hard disk, destination number is not powered on hard disk Electricity.

When destination number is less than the quantity for not powering on hard disk, illustrate that the quota electric current surplus of power supply is not enough to load All hard disks that do not power on power on, only can load target quantity do not power on hard disk, therefore destination number is not powered on hard Disk is powered on, on the one hand, and the quota electric current surplus of power supply is made full use of, is reduced hard disk total starting time, it is another Aspect is accurately controlled the newly-increased quantity for powering on hard disk according to quota electric current surplus, it is possible to prevente effectively from power supply occurred Situations such as stream.

Step 140-3: when destination number is greater than or equal to the quantity for not powering on hard disk, all are not powered on hard disk Electricity.

When destination number is greater than or equal to the quantity for not powering on hard disk, illustrate that the quota electric current surplus of power supply can Load it is all do not power on hard disk, therefore all hard disks that do not power on are powered on immediately, make all hard disk electrifying startups, Hard disk total starting time is reduced, starts hard disk as early as possible.

Due to needing to power on to not powering on hard disk, it is therefore desirable to the quantity for not powering on hard disk is predefined, Fig. 7's On the basis of, refering to Fig. 8, the embodiment of the present application also provides another hard disk electrification control methods.

Before step 140, hard disk electrification control method further include:

Step 131: obtaining the quantity of hard disk in place and powered on the quantity of hard disk.

The quantity of hard disk in place refers to the quantity that hard disk is installed on backboard, and the quantity for having powered on hard disk, which refers to, to be had already powered on The quantity of hard disk.

On the basis of Fig. 8, refering to Fig. 9, step 131 includes following sub-step:

Step 131-1: the quantity of hard disk in place is obtained.

Specifically, hard disk in place refers to the hard disk being mounted on the socket of backboard, if the socket on backboard is equipped with hard disk, It is then in place for hard disk, it is not in place for hard disk if the socket on backboard is not installed with hard disk.The quantity of hard disk in place can be by hard Disk detection circuit detection identification in place, once being correctly equipped with hard disk on backboard on socket, then no matter power on or not powering on, can It is detected and identifies by detection circuit in place, for example, the hard disk being newly inserted into can also be identified as rapidly in place hard when newly insertion hard disk Disk obtains the quantity of hard disk in place, even if obtaining the testing result of hard disk detection circuit in place.

Step 131-2: the quantity for having powered on hard disk is obtained.

It has powered on hard disk quantity and has referred to the hard disk quantity having already powered on, it is relatively, remaining hard in addition to having powered on hard disk Disk does not power on hard disk as.Specifically, each hard disk is correspondingly arranged on a switching circuit, works normally in power supply In the case of, switching circuit control power supply is supplied to the on/off of the hard disk, should if switching circuit control power supply is connected Hard disk is to have powered on hard disk.The quantity for having powered on hard disk is obtained, is to obtain in all switching circuits, the switch of on-state The quantity of circuit.

It should be noted that both step 131-1, step 131-2 have no precedence relationship in logic, the two be can be simultaneously Capable.

Step 132: determine and do not power on the quantity of hard disk, do not power on hard disk quantity be hard disk in place quantity with powered on The difference of the quantity of hard disk.

In addition to having powered on hard disk, remaining hard disk does not power on hard disk as, therefore, using hard disk in place quantity, that is, it is total Hard disk quantity ask poor with the quantity for having powered on hard disk, it can determination does not power on the quantity of hard disk.

By the judgement to hard disk quantity is not powered on, it can accurately control and power on hard disk quantity, make not power on hard disk It powers in time, improves the efficiency of power supply, reduce the total starting duration of hard disk, when new hard disk insertion, that is newly inserted into is hard Disk can be also identified rapidly, to start in time.

It is to be appreciated that being to be powered on for the first time to hard disk, power supply real-time current is if having powered on hard disk quantity is 0 0, peak value of the power supply real-time current in preset duration is also 0, and quota electric current surplus at this time is quota electric current itself.At this time According to the newly-increased destination number for powering on hard disk that quota electric current surplus and single hard disk maximum starting current determine be to hard disk into The hard disk quantity that row is chosen when powering on for the first time.

Above-described embodiment is the control when power supply real-time current is less than quota electric current, to not powering on hard disk and being powered on Method, in the embodiment of the present application, power supply real-time current is excessive beyond power supply electricity during hard disk electrifying startup in order to prevent The power supply capacity in source leads to power supply overcurrent or overload, on the basis of Fig. 5, refering to fig. 10, and present invention also provides another Kind hard disk electrification control method.

Prior to step 110, hard disk electrification control method further include:

Step 101: obtaining power supply real-time current.

Power supply real-time current refers to that power supply is supplied to all real-time currents for having powered on hard disk.For example, hard disk includes It has powered on hard disk and has not powered on hard disk, and powered in hard disk, and included the hard disk in the start-up course and have been started up Complete the hard disk under normal operating conditions.Hard disk electric current in start-up course is generally the electricity of the hard disk under normal operating conditions 2~3 times of stream are changing when power supply real-time current, when hard disk is in difference constantly so during hard disk electrifying startup State when, the electric current that power supply is supplied to power supply is different, in the embodiment of the present application, to power supply be supplied to it is all The electric current for powering on hard disk is detected, and obtains power supply real-time current in real time.

Step 102: power supply real-time current is compared with quota electric current.

Power supply real-time current is that power supply is supplied to all electric currents for having powered on hard disk in real time, and quota electric current refers to power supply Power supply is supplied to hard disks that the maximum current that all hard disks are able to use or power supply provide, all and is able to use most Power supply real-time current is compared big power supply capacity with quota electric current, is whether confirmation power supply works in safe model In enclosing, it is possible to understand that ground, if power supply real-time current is greater than quota electric current, hard disk power consumption has had exceeded power supply can be steady Surely it is supplied to the net capability of hard disk, overcurrent protection may be triggered；If power supply real-time current is less than quota electric current, say Bright hard disk power consumption is without departing from the maximum current that all hard disks are able to use, and there is also quota electric current surplus, Ke Nengzhi for power supply More hard disk electrifying startups are held, are not overloaded or overcurrent.When power supply real-time current is equal to quota electric current, then show on Electric hard disk exhausts the maximum current that all hard disks are able to use just.

When confirming that power supply real-time current is less than quota electric current, power supply there may be quota electric current surplus, so as to It can support more hard disk electrifying startups, execute step 110.If confirm that power supply real-time current exceeds quota electric current, step is executed Rapid 150.

Step 150: when power supply real-time current is greater than quota electric current, closing target hard disk.

When power supply real-time current is greater than quota electric current, i.e., all electric currents for having powered on hard disk have had exceeded power supply The net capability that the maximum current or power supply for distributing to all hard disks are capable of providing, power supply may touch Overcurrent protection is sent out, is shut down caused by power supply triggering overcurrent protection in order to prevent, prevents from having powered on hard disk business being affected, when When power supply real-time current is greater than quota electric current, target hard disk is closed.Target hard disk, which refers to, all has powered on last batch of in hard disk One or more of hard disk powered on.

It is to be appreciated that power supply real-time current can be effectively reduced by closing target hard disk, triggering overcurrent protection, energy are prevented It enough prevents power supply triggering overcurrent protection and stops working, reduce hard disk total starting time.In a kind of feasible embodiment party In formula, the quantity of target hard disk can be according to the difference and single hard disk maximum starting current of power supply real-time current and quota electric current It determines, i.e. the ratio of the maximum starting current of the amount according to power supply real-time current beyond quota electric current and single hard disk determines that target is hard The quantity of disk.

When power supply real-time current is equal to quota electric current, power supply can not support more hard disk electrifying startups at this time, Otherwise it will lead to power supply real-time current beyond quota electric current.But it is understood that hard disk during electrifying startup, opens Streaming current is not continuously maintained in maximum starting current state, but does not stop variation, therefore during hard disk startup, electricity Source real-time current will not be in the state equal with quota electric current for a long time, if there is power supply real-time current equal to quota electric current State then persistently carries out detection to power supply real-time current until power supply real-time current is more than or less than quota electric current.

In alternatively possible embodiment, when power supply real-time current is equal to quota electric current, still available electricity Peak value of the source real-time current in preset duration, it is to be understood that when power supply real-time current exceeds quota electric current, can stand Target hard disk is closed, power supply real-time current can decline, and therefore, when power supply real-time current is equal to quota electric current, power supply is real-time Peak value of the electric current in preset duration namely it is equal to quota electric current, quota electric current surplus is 0 at this time, true according to quota electric current surplus The fixed newly-increased hard disk quantity that powers on is 0.

After target hard disk is closed, power supply real-time current changes accordingly, whether there is so as to redefine Quota electric current surplus powers on hard disk and carries out control up to all hard disk electrifying startups, or to new target hard disk progress It closes.

Part hard disk uses multiple feed, when hard disk has multiple power supplies, on the basis of Fig. 6 and Figure 10, Another implementation of the embodiment of the present application offer hard disk electrification control method.Refering to fig. 11, hard disk electrification control method packet It includes:

In a kind of feasible embodiment, when hard disk has multiple power supplies, multiple power supplies are independent to hard Disk is powered, and when multiple power supplies are simultaneously powered hard disk, hard disk can normally work on power.It is understood that Ground will affect if there is the triggering overcurrent protection of any one power supply to cause to stop working and all power on the normal of hard disk Work.

Each power supply corresponds to different electrical power real-time current, correspondingly, each power supply corresponds to different match Volume electric current.The power supply real-time current of each power supply is compared with its quota electric current, judges whether power supply is deposited The case where exceeding power supply capacity, the power supply real-time current of any one power supply exceeds its quota electric current if it exists, executes Step 150；If the power supply real-time current of each power supply is respectively less than quota electric current, 110 are thened follow the steps.

Step 150: when the power supply real-time current of any one power supply is greater than quota electric current, closing target hard disk.

When being greater than its quota electric current there are the power supply real-time current of any one power supply, target hard disk is closed.Mesh Mark hard disk refer to it is all powered on one or more of the hard disk that last batch of in hard disk powers on, when existing, any one power supply is electric When the power supply real-time current in source is greater than quota electric current, i.e., closing target hard disk, closing target hard disk can be effectively reduced power supply Real-time current prevents any one power supply from triggering overcurrent protection, all power supplies is made to work in safe range, It can prevent power supply triggering overcurrent protection and stop working, reduce hard disk total starting time, improve the effect of power supply Rate.

In a kind of feasible embodiment of the embodiment of the present application, the determination of target hard disk can also be according to the confession of hard disk Electric situation is determined.For example, in conjunction with refering to system architecture shown in Fig. 3, when the first power supply and second source are respectively to difference Hard disk supply power supply when, if the real-time current of the first power supply exceed the corresponding quota electric current of the first power supply, preferentially from first Target hard disk is determined in the hard disk of power supply power supply；If the real-time current of second source exceeds the corresponding quota electric current of second source, Target hard disk is then preferentially determined from the hard disk that second source is powered.Generally, when the power supply of any one power supply is real-time When electric current is greater than quota electric current, i.e., it can close target hard disk.Once the power supply real-time current for multiple power supplies occur is all larger than When quota electric current, then determined target hard disk to prevent beyond power supply respectively according to the electric power thus supplied of each power supply Power supply capacity.

In the feasible embodiment of another kind of the embodiment of the present application, for example, system tray shown in reference to Fig. 4 Structure, the hard disk powered simultaneously by the first power supply and second source if it exists, when the real-time current of the first power supply exceeds the first power supply Corresponding quota electric current then preferentially determines target hard disk from the hard disk that the first power supply is individually powered；If second source is real-time When electric current is beyond second source corresponding quota electric current, then target hard disk is preferentially determined from the hard disk that second source is powered；If When first power supply and second source power supply real-time current occur greater than the case where quota electric current simultaneously, then preferentially from by the first power supply And target hard disk is determined in second source while the hard disk powered.
