The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Referring to Figure 1, a preferred embodiment of a server system 1 of the present invention is shown. In the present embodiment, the server system 1 is described by taking a 2U-4 node rack-mounted server as an example. The so-called "U" refers to the thickness unit of the servo casing. The "U" of each unit is 1.75 inches, which is about 44.45 centimeters. Therefore, the 2U means that the thickness of the rack server is about 88.9 cm. "Node" refers to the server module included in the rack server. Therefore, the 4 node means that the server contains four independently operable server modules. However, in other embodiments of the present invention, the server system 1 may also be a different type of server such as a blade server, and the size of the server and the number of the server modules included may be as needed. Adjustments are not limited to the above.

Specifically, the server system 1 of the present invention can be operated with a remote computer 2 or a control device 3, and includes a transmission interface 10, a first server module 11, and a first power distribution module 12. a second server module 13, a second power distribution module 14, a third server module 15, a third power distribution module 16, a fourth server module 17, and a fourth power distribution The module 18 and a power module 19.

The transmission interface 10 includes various types of transmission ports (not shown in the figure), such as universal serial transmission (USB), network transmission, basic input/output transmission, and image transmission, for the remote computer 2 to access the Internet. The road exchanges data with the server system 1, or provides a display device 3 such as a screen, a keyboard, a mouse, and the like.

The first server module 11, the second server module 13, the third server module 15, and the fourth server module 17 are four nodes (4 nodes) of the rack server, and each A first processing unit 111, a second processing unit 131, a third processing unit 151, and a fourth processing unit 171 for signal processing are included. Here, the processing units 111, 131, 151, and 171 refer to central processing units (CPUs) of the respective server modules 11, 13, 15, and 17, but the processing units 111, 131, 151, and 171 It is also possible to further include various control chips in the server modules 11, 13, 15, 17 without being limited to the central processing unit. In addition, the server modules 11, 13, 15, and 17 respectively include components such as a motherboard, a memory, a hard disk, and the like, but are not drawn one by one in FIG. 1 in order to simplify the subsequent description.

The first power distribution module 12, the second power distribution module 14, the third power distribution module 16, and the fourth power distribution module 18 are electrically connected to the power module 19, which respectively distributes the power of the power module 19. Provided in the first server module 11, the second server module 13, the third server module 15, and the fourth server module 17, and each has a corresponding calculation first server module 11, second The first power detector 121, the second power detector 141, and the third power detector of the power consumption values when the server module 13, the third server module 15, and the fourth server module 17 operate 161 and fourth power detection 181. That is to say, through the read value display of the power detectors 121, 141, 161, and 181, the user can separately monitor the power consumption of the server modules 11, 13, 15, 17 in a specific operating state. In addition, the power consumption values detected by the power detectors 121, 141, 161, and 181 on the server modules 11, 13, 15, and 17 can also be stored as data files for the user to check, or for the server system. 1 Refer to when performing the automatic management program.

The power module 19 includes a power supply unit 191 for converting AC power to DC power to provide operation of the server modules 11, 13, 15, and 17, and calculating the operation of the server modules 11, 13, 15, and 17 Total power consumption value. Here, the total power consumption value is the sum of the individual power consumption values of the server modules 11, 13, 15, and 17. For example, if the power consumption values of the server modules 11, 13, 15, 17 are 110 watts, 100 watts, 95 watts, and 105 watts, respectively, the total power consumption value displayed by the power module 19 is 410 watts.

Generally, the operation of the server system 1 is performed by the user through the remote computer 2 or the control device 3, and one of the server modules is set as the master server module, and the other server modules are set. The servo system 1 is controlled by the slave server module and mainly by the master server module. In the following paragraphs, the first server module 11 is used as the main server module, and the second server module 13, the third server module 15 and the fourth server module 17 are used as slave servos. The architecture of the module is taken as an example to describe the power management method of the server system 1. However, according to the needs of the user, the settings of the master server module and the slave server module can be adjusted accordingly, and are not limited to the specific implementation manner.

Hereinafter, a first power management method of the server system 1 of the present invention will be described with reference to FIGS. 1 and 2.

Step S1: The first processing unit 111 of the first server module 11 (the main server module) receives a setting command sent by the user via the remote computer 2 or the control device 3, and sets all the servos according to the setting command. The total power consumption threshold or the total power threshold threshold of the modules 11, 13, 15, and 17. The total power consumption upper threshold and the total power lower threshold are a target set value, and the server modules 11, 13, 15, 17 adjust the total power consumption value according to the threshold value. For example, the total power consumption upper threshold can be set to 400 watts, and the total power lower threshold is set to 390 watts, but the above threshold settings can be adjusted as needed, and are not limited to the values disclosed herein.

Step S2: The first processing unit 111 of the first server module 11 determines whether to further receive the detection command issued by the user. If the result of the determination is that it has been received, step S3 is performed; if the result of the determination is not received, the transmission of the detection command is further awaited.

Step S3: The first processing unit 111 of the first server module 11 sends a read command to the power module 19, so that the power module 19 returns the total power consumption value of the server modules 11, 13, 15, and 17. .

Steps S4, S5: The first processing unit 111 of the first server module 11 compares the total power consumption value of the server modules 11, 13, 15, 17 with the total power consumption threshold, if the current total If the power consumption value is greater than the total power consumption upper threshold, step S6 is further performed; if the comparison result is negative, step S3 is re-executed.

Step S6: It is assumed that the total power consumption value of the server modules 11, 13, 15, 17 is 410 watts, which is greater than 400 watts set by the total power consumption upper threshold, so the first processing unit 111 of the first server module 11 According to a ranking rule set by the user, the server modules 11, 13, 15, 17 set by the order rule execute the operating state reduction program of the processing units 111, 131, 151, and 171 to reduce the total power consumption. The value, and then re-execute the reading and comparison procedure of the total power consumption value.

The following is a description of the reduced-order program and the upgraded program of the processing units 111, 131, 151, and 171 by taking a central processing unit (CPU) manufactured by Intel as an example. Specifically, the foregoing central processing unit has an operating state such as a P-state (performance state) and a T-state (throttling state), and can adjust the operating class according to the performance required by the server or the power saving requirement. In the case of P-state, the state can be divided into multiple operating classes (for example, from the 0th to the 13th order), and the performance of the central processor (operation clock) and power demand will vary from the 0th to the The 13th order descends sequentially. That is to say, after the operating class is reduced, the central processing unit performs data calculation with a slower operating clock and consumes less power. Therefore, after the processing units 111, 131, 151, and 171 are executed in this step, the power consumption is saved, and the total power consumption value is reduced.

Although the reduced-order procedure can achieve the purpose of power saving, it also reduces the performance of the processing units 111, 131, 151, and 171 that perform the reduced-order procedure. Therefore, it is necessary to maintain a balance between maintaining performance and power saving through a mechanism. In this embodiment, the server system 1 is achieved by a ranking rule.

Specifically, the user can set the execution order of the reduced order program according to the individual performance or power saving requirements of the server modules 11, 13, 15, and 17. For example, in each of the server modules 11, 13, 15, and 17, the data processing amount is the first server module 11, the third server module 15, and the fourth server module 17 in large order. And the second server module 13, that is, the first processing unit 111 of the first server module 11 needs to perform optimal performance, and the second processing unit 131 of the second server module 13 can be the most compact. Perform performance execution operations.

Therefore, if the user prioritizes execution performance, the reduced-order procedure of the central processing unit should be executed with the highest priority of the second server module 13, and the first server module 11 is executed last, that is, used. The order rule can be set such that the second server module 13 performs the step-down procedure with the highest priority, the fourth server module 17 times, the third server module 15 again, and the first server module 11 Finally executed. In this way, setting the order rule according to performance, power saving or other conditions can ensure that the server system 1 provides sufficient computing performance while saving power.

In addition, since the power consumption reduction procedure described above is repeatedly executed until the total power consumption value is not higher than the total power consumption upper threshold. Therefore, preferably, in this continuous power consumption reduction procedure, the operating level of the processing units 111, 131, 151, and 171 will wait for a period of time after each step of the operation, until the servo system 1 is in a stable state. Perform the next step-down procedure to ensure stable operation of the server system 1.

On the other hand, the step of increasing the processing units 111, 131, 151, 171 is similar to the step of reducing the steps, so no further details are provided herein.

Step S7: The first processing unit 111 of the first server module 11 determines whether the total power consumption value of the server modules 11, 13, 15, 17 is less than the total power consumption lower threshold, and if the determination result is "Yes", Then, step S8 is performed; if the result of the determination is "NO", step S6 is re-executed, and the step-down procedure of the processing units 111, 131, 151, and 171 is continued to reduce the total power consumption value.

Step S8: If the total power consumption value (for example, 385 watts) of the server modules 11, 13, 15, 17 is less than the total power consumption lower threshold (for example, 390 watts), it indicates that the server system 1 has sufficient power limit. The processing unit 111, 131, 151, 171 enhances its operating clock to provide better performance, so the first server module 11 will itself or other server modules 13, 15 according to the above-mentioned order rule. 17 an upgrade program that performs power consumption. The specific content of the upgrade program is similar to the step S6, and the operation clocks of the processing units 111, 131, 151, and 171 are gradually increased in a similar manner, and thus will not be further described herein.

Step S9: The first server module 11 determines whether an interrupt command issued by the user is received, and the command is used by the remote computer 2 or the control device 3 when the user wants to end the automatic power management process of the server system 1. issue. Therefore, if the first server module 11 receives the interrupt command, the server system 1 stops the power management program. On the other hand, if the first server module 11 does not receive the interrupt instruction, step S7 is re-executed to determine whether to perform an ascending or descending procedure.

In summary, the first power management method of the present invention is that the first server module is accessed by the user through the remote computer 2 via the Internet. 11 (the main server module) issues an instruction, or the first server module 11 is operated by the local control device 3. After receiving the setting command, the detecting command or the interrupt command, the first server module 11 executes the corresponding program itself and issues a control command to the server modules 13, 15, and 17 (from the server module). The server modules 13, 15, 17 are caused to execute the program they should follow.

Further, the power management mode is to set the total power consumption upper threshold value and the total power consumption lower threshold value of the server modules 11, 13, 15, and 17 through the first server module 11, and in the server mode. When the total power consumption value of the groups 11, 13, 15, and 17 exceeds the total power consumption threshold, the servo modules 11, 13, 15, and 17 are individually adjusted to reduce the power consumption value according to the order rule, and according to the total The setting of the power consumption lower threshold value makes the total power consumption value of the servo system 1 tend to match the total power consumption lower threshold value to achieve the power management effect and the performance of the server system 1 is considered. In addition, since the method can separately set the order rule of the power consumption adjustment of the server modules 11, 13, 15, and 17, respectively, the method has excellent management flexibility. Moreover, when the first server module 11 is repaired or repaired, the user can set other server modules 13, 15, and 17 as the main server module, and the power management method can be similarly executed.

Next, a second power management method of the server system 1 of the present invention will be described with reference to Figs. 1 and 3. The difference between this method and the first power management method is that the user directly sets individual power consumption upper thresholds and power lower thresholds for each server module 11, 13, 15, and 17 to allow each server. Modules 11, 13, 15, and 17 perform their power management procedures Therefore, it is not the total control of the total power consumption value of the server modules 11, 13, 15, 17 through the total power consumption threshold and the total power threshold. Specifically, the second power management method includes the following steps:

Step F1: The first server module 11 (main server module) or any of the server modules 13, 15, 17 (from the server module) receives a setting command issued by the user, and according to the setting instruction Set its power cap threshold or power lower threshold. For example, the user can specify that the power consumption upper threshold of the first server module 11 is 105 watts, and the power consumption lower threshold is 95 watts. Similarly, other server modules 13, 15, 17 can also be set by the user to set their power consumption threshold.

Step F2: any of the server modules 11, 13, 15, 17 determines whether it receives a detection command itself. If the determination result is "Yes", only the server modules 11 and 13 that receive the detection command are received. Steps F3 are executed, 15, and 17; if the result of the determination is "No", the subsequent instructions are awaited.

Steps F3 and F4: The server modules 11, 13, 15, and 17 that receive the detection command issue a read command to their corresponding power distribution modules 12, 14, 16, 18 to read the power of their current operation. The value is consumed, and the power consumption value is further compared with the power consumption upper threshold or the lower power threshold.

Step F5: The server module 11 , 13 , 15 , 17 receiving the detection command determines whether the power consumption value is greater than the power consumption upper threshold. If the determination result is “Yes”, the step F6 is performed; otherwise, the step F3 is performed again.

Hereinafter, in order to simplify the description, the first server module 11 will be described as an example, but the power supplies of other server modules 13, 15, and 17 are as follows. The management execution method is also the same.

Step F6: The server modules 11, 13, 15, and 17 that receive the detection command perform a reduced-order procedure of the power consumption of the processing units 111, 131, 151, and 171. For example, assuming that the power consumption value of the first server module 11 is 110 watts, which is greater than its power consumption upper threshold (105 watts), its first processing unit 111 must perform a reduced-order procedure to reduce power consumption, and Reads, alignments, and reduced-order programs of their power consumption values must be repeated until the power consumption value is less than the power-down threshold (for example, 95 watts).

Steps F7 and F8: The server module 11, 13, 15, 17 receiving the detection command has a power consumption value smaller than its power consumption lower threshold. If its power consumption value is less than its power lower limit threshold, an upgrade procedure for power consumption is performed. If it is the opposite judgment result, step F6 is performed.

It is assumed that after the end of a certain step-down procedure, the power consumption value of the first server module 11 is reduced to 90 watts, and there is a power supply limit of 5 watts compared with the power consumption threshold (95 watts), so the first The first processing unit 111 of the server module 11 can perform its upgrade procedure correspondingly to improve its operational efficiency.

Step F9: If any of the server modules 11, 13, 15, 17 receives an interrupt command issued by the user, it stops the power management process. If the interrupt command is not received, step F7 is executed, and its power consumption value is stably adjusted to match the power consumption lower threshold.

As described above, the second power management method of the server system 1 of the present invention is that the user directly performs power consumption setting and power management procedures for each of the server modules 11, 13, 15, and 17, thus having the largest management bullet. And there is no need to worry about the power management of the other server modules 13, 15, 17 when the first server module 11 (main server module) fails, and provide better reliability.

It should be particularly noted that, in the above description, both of the power management methods are issued by the user to the server module 11, 13, 15, 17 to set a command or detect the command, but the server system of the present invention 1 It can also be set to the target setting value such as the total power consumption upper threshold value, the total power consumption lower threshold value, the power consumption upper threshold value, and the power consumption lower threshold value automatically set by the server system 1.

For example, the first server module 11 can automatically set the total power consumption upper threshold or the total power lower threshold by referring to the historical data of the total power consumption value provided by the power module 19, for example, the computing server system 1 The average value of the total power consumption value for a specific time, and the value of 90% of the average value is taken as the total power consumption upper limit threshold value, and the value of 70% of the average value is taken as the total power consumption lower limit threshold value. On the other hand, the server modules 11, 13, 15, and 17 can also automatically set the upper limit threshold and power consumption of the power consumption according to the historical data of the power consumption values provided by the power distribution modules 12, 14, 16, and 18. The lower threshold is the threshold. After completing the above automatic setting procedure, the server system 1 can automatically execute the power management program based on the above threshold value.

In addition, the power consumption adjustment method described in the above is achieved by the processing units 111, 131, 151, and 171 of the respective server modules 11, 13, 15, and 17 performing the step-up or step-down procedure of the operating class thereof. However, the power consumption adjustment method can also be achieved by power management of components such as memory and hard disk in the server modules 11, 13, 15, and 17, which are not disclosed above. Tolerance is limited.

In summary, the user can perform power management on the server system 1 of the present invention through the above two methods. Since the two methods can perform power consumption management or setting on individual server modules 11, 13, 15, and 17, they have good management flexibility and flexibility.
