In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 2, the embodiment of the present invention provides another method for power supply of a server, and the method may include the following steps:

Step 201: Set a function option for turning on and off setting the first threshold and the second threshold on the function address of the redundant power supply.

Assuming that there is a redundant power supply R, the redundant power supply R serves as a server power supply to supply power to the server S to support the normal operation of the server S. Since the load of the server S is variable during actual operation, in order to make the redundant power supply R use different power supply modes according to different load levels, two thresholds can be set. When the input current of the redundant power supply R is lower than a certain threshold, the redundant power supply R supplies power in active+standby mode, and when the input current of the redundant power supply R is higher than a certain threshold, the redundant power supply R supplies power in current sharing mode.

Among them, the more running tasks of the server S, the heavier the load of the redundant power supply R, the correspondingly higher input current of the redundant power supply R, on the contrary, the less the running tasks of the server S, the lighter the load of the redundant power supply R , the input current of the redundant power supply R is correspondingly lower.

In detail, in the current sharing mode, each of the two power supplies in the redundant power supply shares 50% of the load. Among them, the load is allowed to vary by 5% to 10%.

In detail, in the active+standby mode, one of the redundant power supplies acts as an active power supply and bears all loads, and the other power supply acts as a standby power supply and is in a standby state. Wherein, the redundant power supply can input dual AC current, or input dual DC current, or any one of the power sources can input DC power, and the other power source can input AC power. Users can choose any power supply as the active power supply and the other power supply as the standby power supply according to actual needs.

For example, in the process of programming the system software, a function option can be set on the function address of the server power supply, through which the setting of the first threshold and the second threshold can be selected to be enabled or disabled.

Step 202: Start setting the first threshold and the second threshold.

In order to enable the redundant power supply R to use different power supply modes according to different load levels of the servers S, the setting of the first threshold and the second threshold is enabled.

Obviously, if the settings of the first threshold and the second threshold are turned off, the redundant power supply R can only provide power to the server S in the same working mode, regardless of whether the server S is loaded or not. For example, the redundant power supply R Provide power to server S in current sharing mode.

Step 203: Set a first threshold and a second threshold of the redundant power supply, and set a working mode of the redundant power supply during operation according to the first threshold and the second threshold.

Specifically, the first threshold may be set to be no greater than the second threshold. According to the first threshold and the second threshold, it can be set that when the input current of the redundant power supply is not less than the second threshold during operation, the operating mode of the redundant power supply during operation is current sharing mode; when the input current of the redundant power supply is not greater than the first threshold value during operation, the working mode of the redundant power supply during operation is active+standby mode; when the redundant power supply is running When the input current is greater than the first threshold but less than the second threshold, the operating mode of the redundant power supply during operation is to maintain the current operating mode of the redundant power supply.

When the first threshold is equal to the second threshold, it is equivalent to setting only one threshold. Therefore, when the input current of the redundant power supply R is greater than the threshold, the redundant power supply R supplies power in the current sharing mode. When the redundant power supply R When the input current of the redundant power supply R is less than the threshold value, the redundant power supply R is powered in active+standby mode, so that its working mode is continuously adjusted according to the change of the input current of the redundant power supply R, and automatic intelligent switching of different working modes can also be realized according to the weight of the load. . However, when the input current of the redundant power supply R jumps repeatedly at this threshold, the working mode of the redundant power supply R will be continuously switched, which will have certain impacts on the stability, energy consumption, and service life of the redundant power supply R. Impact. Therefore, this embodiment does not give too many detailed descriptions.

Preferably, the first threshold may be set to be smaller than the second threshold, and in addition, the absolute value of the difference between the first threshold and the second threshold may be 3˜5A.

Specifically, when the first threshold is smaller than the second threshold, a current value range that is larger than the first threshold but smaller than the second threshold is used as a transition zone.

Wherein, for the two critical values of the first threshold and the second threshold, the transition zone may contain both the first threshold and the second threshold, or may only contain the first threshold but not include the second threshold, may only include the second threshold but not include the first threshold, and may also include neither the first threshold nor the second threshold, which is not made in this embodiment. Specific limits.

After enabling the setting of the first threshold and the second threshold, the first threshold and the second threshold of the redundant power supply R may be set. Generally, the specific current values of the first threshold and the second threshold can be set according to factors such as experiences and rules, and the difference between them is 3-5A. For example, according to various comprehensive factors such as the daily load of the server S, the variation range and frequency of the input current of the redundant power supply R, other commonly used servers, the variation rules of relevant parameters of the redundant power supply, and the experience of professional operators, The first threshold of the redundant power supply R can be set to 23A, the second threshold to 26A, the difference between the first threshold and the second threshold is 3A, and the current range between 23A and 26A is a transition zone. Of course, according to specific needs, both the first threshold and the second threshold can be set to other values, and the difference between the two is not limited to 3-5A, for example, the difference between the two can be 2A, 6A, etc.

Step 204: According to the first threshold and the second threshold, set the working mode of the redundant power supply when starting.

Specifically, it is set that when the input current of the redundant power supply is not less than the second threshold value at startup, the working mode of the redundant power supply at startup is the current sharing mode; When the input current of the redundant power supply is not greater than the first threshold value, the working mode of the redundant power supply at startup is active+standby mode; when the input current of the redundant power supply at startup is set in the transition zone, the redundant power supply The working mode of the power supply at startup is any one of current sharing mode and active+standby mode. For example, when the input current of the redundant power supply is set to be in the transition zone at startup, the working mode of the redundant power supply at startup is active+standby mode.

For example, when the server S starts up, it is generally in a light load state, and the input current of the redundant power supply R is usually located in the transition zone. In order to save energy consumption as much as possible, you can set the working The mode is active+standby mode, but if necessary, the working mode of the redundant power supply R at startup can also be set to the current sharing mode.

Step 205: When the server starts up, according to the setting information of the working mode of the redundant power supply at startup, determine the working mode of the redundant power supply R at startup according to the input current of the redundant power supply R at startup.

In detail, in this embodiment, the input current of the redundant power supply R refers to the current value of the output working voltage of the redundant power supply R. For example, the output working voltage of the redundant power supply R can be 12V, where 12V is the standard output of the server power module, which is the voltage marked by Intel, which is obtained by converting the 220V mains power through the hardware circuit.

For example, the server S is powered on, and the redundant power supply R supplies power to the server S. Firstly, it is determined that the input current of the redundant power supply R at startup is 25A. According to the setting information of the working mode of the redundant power supply at startup, it is judged that 25A is located in the transition zone, so it is determined that the redundant power supply R is at startup. The working mode is active+standby mode.

Step 206: Determine the current working mode of the redundant power supply R and the current input current of the redundant power supply R.

For example, it is assumed that the load level of the server S does not change after the server S is started, so the input current of the redundant power supply R is always 25A. In order to monitor whether the input current of the redundant power supply R changes in real time, it is first necessary to determine the working mode and input current of the redundant power supply R before the input current changes, that is, the current working mode of the redundant power supply R and the current input of the redundant power supply R current. For example: the current working mode of the redundant power supply R is active+standby mode, and the current input current of the redundant power supply R is 25A.

Step 207: Monitor the input current of the redundant power supply R, and execute step 208 when it is detected that the input current of the redundant power supply R changes.

In order to realize the automatic and intelligent switching of the working mode of the redundant power supply R, it is necessary to monitor the input current of the redundant power supply R in real time. When it is detected that the input current of the redundant power supply R changes, the next step is executed; if the input current of the redundant power supply R does not change, the redundant power supply R maintains its current working mode. For example, suppose it is detected that the input current of the redundant power supply R changes from 25A to 27A.

Step 208: According to the first threshold and the second threshold, the current working mode of the redundant power supply R, and the input current of the changed redundant power supply R, determine the difference between the input current of the changed redundant power supply R and The relationship between the first threshold and/or the second threshold determines the next working mode of the redundant power supply R.

Specifically, when the judgment result includes that the input current of the changed redundant power supply R is not less than the second threshold, it is determined that the next working mode of the redundant power supply R is the current sharing mode; when the judgment result includes the changed When the input current of the redundant power supply R is not greater than the first threshold, it is determined that the next operating mode of the redundant power supply R is active+standby mode; the judgment result includes the input current of the changed redundant power supply R When it is greater than the first threshold but less than the second threshold, it is determined that the next working mode of the redundant power supply is the current working mode of the redundant power supply R.

For example, according to the first threshold value of 23A, the second threshold value of 26A, the current working mode of the redundant power supply R is active+standby mode, and the input current of the changed redundant power supply R is 27A, it can be judged that 27A is greater than 26A , that is, the changed input current of the redundant power supply R is greater than the second threshold, so it is determined that the next working mode of the redundant power supply R is the current sharing mode.

Step 209: When the next working mode of the redundant power supply R is different from the current working mode of the redundant power supply R, switch the working mode of the redundant power supply R to the next working mode, and perform step 206; otherwise, Maintain the current working mode of the redundant power supply R, and execute step 206 .

In detail, the switching between the two working modes of the redundant power supply R is realized through the change of the voltage of the Ibus inside the power supply module.

For example, since the current working mode of the redundant power supply R is active+standby mode, and the next working mode of the redundant power supply R is the current sharing mode, the two are not the same working mode, so the working mode of the redundant power supply R Automatically switch from active+standby mode to current sharing mode.

In this embodiment, according to the actual load level, automatic intelligent switching between the current sharing mode and the active+standby mode of the redundant power supply R can be realized. When the redundant power supply R is lightly loaded, the active+standby mode is used to For power supply, one of the power supplies works normally and bears the full load, and the other power supply is automatically in the standby state, consuming only a small amount of standby energy; when the redundant power supply R is overloaded, it uses the current sharing mode to supply power to the server, and automatically wakes up the standby power supply. Both power supplies are working normally, and each share 50% of the load. Therefore, according to the needs of the actual load, through the automatic and intelligent switching of the working mode of the redundant power supply R, it can ensure that the redundant power supply R always maintains the optimal working efficiency. state, thereby effectively realizing the energy-saving effect of the redundant power supply R.

Then, in order to monitor whether the input current of the redundant power supply R will change again, it is necessary to continue to execute step 206, that is, to determine the current working mode of the redundant power supply R and the current input current of the redundant power supply R. It can be seen that the current The working mode is the current sharing mode, and the current input current of the redundant power supply R is 27A.

Similarly, after the current working mode of the redundant power supply R and the current input current of the redundant power supply R are determined, the change of the input current of the redundant power supply R is continuously monitored. Assuming that the input current of the redundant power supply R is monitored again to change from 27A to 24A, according to the first threshold 23A, the second threshold 26A, and the current working mode of the redundant power supply R is the current sharing mode, it can be known that 24A is greater than 23A but less than 26A, that is, the input current 24A of the changed redundant power supply R is located in the transition zone, so it is determined that the next working mode of the redundant power supply is the current working mode of the redundant power supply R, that is, the current value of the redundant power supply R is determined by After the 27A is changed to 24A, the working mode of the redundant power supply R is still maintained as the current sharing mode. Then, determine that the current working mode of the redundant power supply R is the current sharing mode, and the current input current of the redundant power supply R is 24A, and on this basis, continue to monitor the input current change of the redundant power supply R, so as to repeat the past and realize The automatic intelligent switching of the working mode of the redundant power supply R keeps the redundant power supply R in the optimal working efficiency state.

In this embodiment, regardless of whether the current working mode of the redundant power supply R is the current sharing mode or the active+standby mode, as long as the input current of the changed redundant power supply R is in the transition zone, the next working mode of the redundant power supply R The mode is the current working mode of the redundant power supply R, that is, to maintain the current working mode of the redundant power supply R until the input current of the changed redundant power supply R is not in the transition zone, it is possible to appear between the two working modes automatic intelligent switching.

For example, the current working mode of the redundant power supply R is the current sharing mode. When the input current of the changed redundant power supply R is greater than the second threshold, the next working mode of the redundant power supply R is still the current sharing mode. Similarly, when When the input current of the changed redundant power supply R is in the transition zone, the next working mode of the redundant power supply R is the current working mode of the redundant power supply R, that is, the current current sharing mode is maintained, and only when the changed redundant power supply R When the input current of the power supply R is less than the first threshold, the next working mode of the redundant power supply R is active+standby mode. When it is different from the current current sharing mode, the working mode of the redundant power supply R changes from the current current sharing mode to The next active+standby mode is automatically and intelligently switched.

When the server S is running normally, when the voltage is unstable and fluctuates, the input current of the redundant power supply R will fluctuate repeatedly in a small range, or other influencing factors may also cause the input current of the redundant power supply R to fluctuate repeatedly, Through the above-mentioned implementation method, the appropriate first threshold and second threshold can be preset according to actual experience, rules and other factors, so that the critical value of the input current of the redundant power supply R that is prone to repeated jumps is in the transition zone, so that Effectively avoid repeated switching of the working mode of the redundant power supply R at the critical value that is prone to repeated jumps, so as to improve the stability of the redundant power supply R, prolong its service life, ensure the quality of the power supply, and reduce energy loss.

2. The embodiment of the present invention provides a method and device for server power supply. According to the actual load level, automatic intelligent switching between the current sharing mode and the active+standby mode of the redundant power supply can be realized. When the redundant power supply is lightly loaded When the power supply is active+standby, use the active+standby mode to supply power to the server. One of the power supplies works normally and bears the full load, and the other power supply is automatically in the standby state, consuming only a small amount of standby energy; when the redundant power supply is overloaded, use the current sharing mode to The server supplies power, automatically wakes up the standby power supply, and both power supplies work normally, and each share 50% of the load. Therefore, according to the needs of the actual load situation, the redundant power supply can be guaranteed through automatic intelligent switching of the working mode of the redundant power supply. Always maintain the state of optimal working efficiency, thus effectively realizing the energy-saving effect of redundant power supply.
