Technical field

The present invention relates to communication technologies, and in particular, to a power consumption capping control method, device and system. Background technique

With the explosive growth of Internet data and the advent of the cloud computing era, the demand for server equipment in the IT field is growing, and the rapid expansion of IT equipment in the data center equipment room brings great challenges to the power supply, heat dissipation, and space capacity of the data center. . On the one hand, there is a shortage of power and resources in the data center. On the other hand, the power consumption of the equipment in the equipment room is low, and the density of the machine is low. Therefore, there is a great waste of resources. At present, the Internet Data Center (hereinafter referred to as IDC) has a limit on the machine rejection of the machine. If the machine refuses to exceed the rated value, it will cause an open trip. When deploying the server, you need to be very cautious. The configuration is calculated according to the rated maximum power consumption, and in actual use, the probability of the power consumption of the server running close to the rated maximum power consumption is extremely small. FIG. 1 is a schematic diagram of a resource usage situation in the prior art. As shown in FIG. 1 , by analyzing resource usage of 5000 servers on the existing network, the idle rate of server resources is more than 50%, and if When the 50% resource caused by power consumption is idle, the idle rate of the entire machine is more than 75%. The power capping technology can solve the above problems. The power capping scheme in the prior art includes three main parts: setting a capping value, monitoring running power consumption, and performing a capping action. That is, first set the power cap value of each rack server according to the machine rejection power supply requirement, the actual power consumption of the normal operation of the server, the service pressure demand, etc., and then write the cap value to the out-of-band management system as the upper limit operation of the server operation. Consumption, the power cap value is a fixed value. During the running of the server, the out-of-band management system monitors the power consumption of the whole machine. If the power consumption exceeds the capping value, the capping action is performed. However, in the prior art, resource allocation and use between servers are independent of each other, and the capping function is not flexible, and resources cannot be used reasonably. Summary of the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

2 is a flowchart of Embodiment 1 of a method for controlling power capping according to the present invention. As shown in FIG. 2, this embodiment provides a control method for power capping, which is from the side of the management board to the present invention. The technical solution is described. In this embodiment, the following steps may be specifically implemented: Step 201: Monitor the power consumption of the entire frame to obtain the entire frame monitoring result. The control method of the power consumption capping provided in this embodiment is mainly directed to the power consumption capping process of the blade server or the multi-node server with the management board, that is, the server in this embodiment may be specifically a blade server or a multi-node server with a management board. The management board provides management functions for each server and chassis, and is responsible for the power consumption of the chassis. When the management board starts to perform power capping control, that is, when the power capping level switch is started, the management board periodically monitors the power consumption of the entire frame, and obtains the entire frame monitoring result in real time. Here, the power consumption of the whole frame monitored by the management board is the power consumption of all the servers and components in the running state of the entire chassis. As the server operates and the external environment changes continuously, the power consumption of the entire frame is also constantly changing. Therefore, in this embodiment, the current value of the entire frame power consumption can be obtained in real time by monitoring. In this embodiment, the monitoring result of the entire frame may be the utilization of the resource pool. For example, if the resource pool overflows, the obtained whole frame monitoring result may be a resource pool overflow or the resource pool does not overflow. The resource pool here is a power resource shared by multiple servers inserted in the same chassis. In this embodiment, multiple servers inserted in the same chassis share one resource pool, that is, multiple servers share power modules. Power supply resources provided. Step 202: When the whole frame monitoring result is that the resource pool does not overflow, the power consumption capping is not performed on each server.

In this embodiment, through the monitoring process of the foregoing steps, when the obtained monitoring result of the entire frame is that the resource pool does not overflow, the management board does not perform power consumption capping operation on each server, but continues to execute the above-mentioned full frame power consumption. Monitoring operation. In this embodiment, under the premise that the resource pool shared by each server does not overflow, the power consumption capping operation of the server is not performed, and the server is allowed to run without limit, even if the power consumption of some servers far exceeds the set server power consumption cap value. The server is also not controlled, so that the speed of some servers can be greatly improved without affecting other servers. Step 203: When the whole frame monitoring result is that the resource pool overflows, send a power consumption capping control instruction to each server, so that each server receives the power consumption capping control instruction and performs power consumption capping control. When the obtained monitoring result of the entire frame is a resource pool overflow, the management board sends a power capping control command to each server, and each server performs power capping control after receiving the power capping control command, which is equivalent to turning on each server. The level capping switch allows the server power consumption of each server after power capping to not exceed the server power capping value. It can be seen that the power capping control in this embodiment is combined with real When monitoring the entire frame power consumption of the entire chassis and the server power consumption of each server, each server shares a resource pool, and resource allocation and use between them are not independent of each other. Therefore, this embodiment is relative to the present The technical capping function is more flexible and can maximize the rational use of resources. This embodiment provides a control method for power capping. By monitoring the power consumption of the entire frame, when the obtained monitoring result of the entire frame is that the resource pool is not overflowed, the power capping operation is not performed on each server. When the resource pool overflows, the power consumption capping control command is sent to each server, so that the servers receive the power consumption capping control command and then perform power capping control. This embodiment implements a more flexible capping function, maximizes the rational use of resources, and greatly reduces the waste of resources. In this embodiment, a capping switch is respectively disposed on each server. When the management board obtains the resource pool overflow by monitoring the power consumption of the entire frame, the capping switch of each server is turned on, where the capping switch is specifically a power cap. Secondary switch. For each server, when the server's top switch is turned on, the board management controller (BMC) unit in the server periodically monitors the server's server power consumption to obtain real-time access. Current server power consumption to the server. In this embodiment, the BMC unit in the server is a power consumption capping secondary switch of the server, and the power consumption capping secondary switch is started to start the BMC unit for power capping control. During the monitoring of the power consumption of the server by the BMC unit, the BMC unit performs power capping control according to the monitored server power consumption and the server power cap value. The server power consumption cap value in this step is obtained by real-time updating of the entire frame power consumption obtained by the management board according to the monitoring, and specifically, in the process of monitoring the power consumption of the entire frame by the management board, the management board obtains the whole according to the monitoring. The box power consumption updates the server power cap value in real time. In this step, the BMC unit in the server combines the server power consumption obtained by real-time monitoring with the server power consumption cap value obtained by real-time monitoring when performing power capping control. Therefore, the power capping control process of the embodiment is flexible. , can maximize the rational use of resources. FIG. 3 is a flowchart of a second embodiment of a method for controlling power capping according to the present invention. As shown in FIG. 3, the embodiment provides a control method for power capping, which may specifically include the following steps: Step 301: The management board is configured according to the following steps: The machine rejects power distribution and service load conditions to set the entire frame power consumption cap value. 4 is a schematic diagram of a system architecture in a second embodiment of a power consumption capping control method according to the present invention. As shown in FIG. 4, it is assumed that N blade servers are inserted in a chassis of the embodiment, that is, a blade server and a blade server. 2, ... blade server N. The management board in the figure is the chassis management board of the blade server. It is used to provide the management function of the blade server and the chassis. It is equivalent to the power capping level switch of the entire chassis including all the blade servers. In this embodiment, Turning on the power consumption capping level one switch is equivalent to starting the management board, and the management board starts to execute the power consumption capping control process in this embodiment. As can be seen from Figure 5, the management board obtains the power consumption of the entire frame of the chassis in real time through the power supply unit (Power Supply Unit; the following package: PSU). The power consumption of the entire frame here is inserted in the chassis. The total power consumption of all blade servers and components during operation; the management board also communicates with each blade server through the "Management Communication" channel to deliver the server power cap value of each blade server in real time. The PSU is used to power each blade server and report the power consumption of the entire frame to the management board in real time through the "management signal line". Each of the blade servers may be composed of a BMC unit, a BIOS, a power consumption detecting unit, and a CPU. The BMC unit is an out-of-band management unit of the blade server, and cooperates with the BIOS of the blade server to implement power capping. Consumption of the top switch. The BIOS is used to receive the control commands of the BMC unit, so as to the operating frequency state of the CPU (the performance state; the following cylinder: P-state) and the clock duty state (Throttle state; the following cylinder: T-state), the memory The P-state and T-state and other components are adjusted to implement the capping action of the blade server. The power consumption detection unit is configured to detect the server power consumption of the entire blade server, and report the detection data to the BMC unit in real time. In this step, before the power management capping control is started on the management board, the management board first sets the power consumption capping value of the entire frame according to the machine rejection and service load. The management board can be specifically based on the machine rejection power supply requirement and the blade server is running normally. The actual power consumption and service pressure requirements are used to configure the power consumption capping value of the entire frame, that is, the machine power rejection requirements are met, and the maximum power and average value of the actual power consumption of the blade server can be combined. For the service pressure requirement, such as the service load situation, the entire frame power consumption capping value is configured. The specific configuration method may be a method well known to those skilled in the art in the prior art, and details are not described herein again. It is assumed here that the configured full frame power consumption cap value is P. , ie P. An initial value for the full frame power consumption cap value. Step 302: The management board calculates a server power consumption capping value of each blade server according to the entire frame power consumption capping value. After the management board sets the power consumption cap value of the entire frame, it can be based on the power consumption cap value of the entire frame. To calculate the server power capping value distributed to each blade server, it is assumed here that the server power capping value is P _m . The calculation method of the server power consumption capping value in this embodiment is to use the entire frame power consumption capping value P. Subtracting the power consumption value p of the components other than the blade server on the chassis to obtain a difference, and then dividing the difference into the in-position blade servers according to the in-position state of each blade server. The components on the chassis other than the blade server may include, for example, a chassis fan, a power supply, a management board, a switchboard, and the like. After the management board calculates the server power cap value P _{m of the} blade server, the management board delivers the P _{m to each in-} position blade server through the "management communication" channel. For example, assuming that all N blade servers are in place and the power consumption of other components is p, the server power consumption capping value P _m can be calculated by the following formula (1): P _m = ^ ( 1 )

Where P _m is the server power cap value, P. For the entire frame power cap value, p is the power consumption value of other components, and N is the number of servers. The calculated server power capping value P _{m here} is also the initial value of the server power capping value, and the server power capping value is further changed according to the running condition of the server. Alternatively, in this embodiment, the server power consumption cap value of some or all of the blade servers may also be manually set according to the traffic load condition. Step 303: The management board monitors the power consumption of the entire frame according to the preset whole frame monitoring period, and updates the server power consumption capping value of each server according to the monitored full frame power consumption.

After completing the setting of the whole frame power cap value and the server power cap value, the management board can be started to control the power capping. After the management board is enabled to control the power capping process, the management board monitors the power consumption of the entire frame according to the preset frame monitoring period. It can be assumed that the entire frame power consumption period can be based on the actual situation. Specific settings, for example, can be set to monitor the power consumption of the entire frame 10 times per second. At the same time, the management board updates the server power consumption cap value of each server according to the power consumption of the whole frame obtained by the monitoring. Specifically, the management board can refresh the server power consumption cap value of each blade server in real time according to the current frame power consumption of the chassis. Calculating an average value of the power consumption of the whole frame and an average value of the total power consumption of the server according to the values of the power consumption of the whole frame and the total power consumption of the server monitored in the preset time period, for example, the management board may The server power capping value is refreshed every second, that is, the preset time period is 1 second, and the value of 10 full-frame power consumption and the total power consumption of 10 servers can be separately monitored in one second; The average power consumption of the server and the average power consumption in one second, the two average values are subtracted to obtain the total power consumption of all components except the blade server P_other; The box power cap value P. Subtract P_other to get a difference, and then divide the difference into each in-position blade server, that is, get the updated server power capping value P _m . Specifically, the following formula can be used.

(2) to update the server power cap value P _m :

p ₌ [P ₀ - (^ - P _N )] _{( 2 )}

m N

Where P _m is the server power cap value, P. The average power consumption of the entire frame is the average value of the power consumption of the entire frame, which is the average value of the total power consumption of the server, and N is the number of servers. In this embodiment, the preset formula is used. The server power consumption cap value of each server is updated. In this embodiment, during the operation of the blade server, the power consumption of the entire frame is different in different time periods. In this embodiment, the power consumption capping value of the computing server is refreshed in real time by monitoring the power consumption of the entire frame, so that the server power consumption is obtained. The capping value can be closer to the current server operation, which can greatly reduce the capping error caused by the inaccuracy of the server power capping value, and improve the accuracy of the capping action in the subsequent steps.

Step 304: The management board determines whether the power consumption of the entire frame obtained by the monitoring is less than the product of the preset upper limit coefficient and the entire frame power consumption cap value. If yes, step 305 is performed; otherwise, step 306 is performed. When each monitor receives a full frame power consumption, the management board determines whether the power consumption of the entire frame is less than a preset upper limit coefficient and a full frame power consumption cap value P. The product, where the upper limit coefficient of the interval can be set or modified according to the actual situation, for example, set to 0.7, then this step is specifically for the management panel to determine the power consumption of the whole frame obtained by monitoring! ^ Is it less than Ρ. '0.7, if yes, go to step 305, otherwise go to step 306. The product of the interval upper limit coefficient and the entire frame power consumption cap value in this embodiment is the upper threshold of the resource pool shared by the blade server, and the interval lower limit coefficient, the interval lower limit coefficient and the entire frame power consumption cap value are also involved in the subsequent steps. The product is the lower threshold of the resource pool, and the range between the upper threshold and the lower threshold constitutes the anti-shock interval of the resource pool. Step 305: The management board obtains the whole frame monitoring result that the resource pool does not overflow, and returns to the execution step.

303. In this embodiment, the power consumption of the entire frame obtained by the management board is less than the accumulation of the preset upper limit coefficient and the entire frame power consumption cap value. If the resource pool is not overflowed, the management board obtains the monitoring result of the entire frame. The management board does not perform any further operations. The management board can perform the above steps 303 and continue to monitor the power consumption of the entire frame. . Step 306, the management board obtains the whole box monitoring result as a resource pool overflow. When the power consumption of the entire frame obtained by the management board is greater than or equal to the preset upper limit coefficient of the interval and the power consumption cap value of the entire frame. If the resource pool is overflowed, the management board obtains the entire box monitoring result as the resource pool overflow, and performs the following step 307. In this embodiment, when the power consumption of the entire frame is lower than the accumulation of the upper limit coefficient of the interval and the power consumption cap value of the entire frame. '0.7, does not perform power capping on the server, allowing all blade servers to run unrestricted, some of them can also run far beyond the server cap value; when the whole frame power consumption reaches the upper limit coefficient and the whole frame power consumption cap value Product P. At 0.7, the power capping control of the blade server is turned on. In step 307, the management board closes the resource pool and sends a power capping control command to each server. When the management board learns that the resource pool overflows, the management board closes the resource pool, and sends a power consumption capping control instruction to each server, so that the servers receive the power consumption capping control command and then perform power consumption capping control, that is, start The BMC unit, which is a power-capped secondary switch in each blade server, begins the operation of power capping control. Step 308: The BMC unit in the blade server monitors the server power consumption of the blade server, and determines whether the monitored server power consumption is less than the server power consumption cap value. If yes, continue to perform step 308, otherwise step 309 is performed. After receiving the power capping control command sent by the management board, the BMC unit in each blade server separately monitors the server power consumption of the respective blade server, and the BMC unit determines whether the monitored server power consumption _Pn is smaller than the above step 307 update. After the server power cap value P _m , if yes, it indicates that the server power consumption of the blade server has not exceeded the server power cap value, and the BMC unit does not perform any action of controlling power consumption, and continues to perform this step 308 to continue monitoring. Server power consumption, otherwise go to step 309. Step 309: The BMC unit sends a cap execution notification to the basic input/output system (Basic Input Output System; BIOS) of the blade server according to the difference between the server power consumption and the server power consumption cap value.

When the resulting BMC unit monitoring server power P _n is greater than or equal to said power capping step 307 the server the updated value P _m, power consumption of the blade server indicating that the server has reached the cap value server power consumption, BMC unit begins execution function The topping action is consumed. Specifically, the BMC sends a cap execution notification to the blade server's BIOS based on the difference between the server power consumption and the server power cap value. Step 310, the BIOS adjusts the central processor of the blade server according to the capping execution notification. (Central Processing Unit; The following cylinders are called: CPU) operating frequency state and clock duty cycle state, as well as the operating frequency state of the memory and the clock duty cycle state. After receiving the capping execution notification, the BIOS of the blade server adjusts the operating frequency state P-state of the CPU of the blade server and the clock duty state T-state according to the capping execution notification, and the memory of the blade server. -state and T-state and the working state of other components of the blade server.

Step 311: The BMC unit determines whether the current monitored server power consumption is less than the server power consumption cap value. If yes, step 312 is performed; otherwise, the process returns to step 310.

In this embodiment, the monitoring operation of the power consumption of the server by the BMC unit is not stopped due to the power capping execution action, that is, in the process of performing the above steps 309-311, the BMC unit still monitors the server power consumption of the blade server at the same time. . Each time the BMC unit performs the power capping action, the BMC unit compares the current server power consumption P _n with the server power cap value P _m to determine whether the current server power consumption P _n is less than the server power consumption. cap value P _m, if yes, step 312 is performed, otherwise step 310 is performed, power capping operation continues.

Step 312: The BMC unit sends a capping execution stop notification to the BIOS of the blade server. When the power after performing capping operation, when the BMC power unit P _n recognizes server updates the server power less than the current capping value P _m, power capping operation has been previously indicated that the power consumption of the blade server in the server power control Below the cap value, the BMC unit sends a cap execution stop notification to the blade server's BIOS.

Step 313: The BIOS stops performing the power consumption capping related operation according to the capping execution stop notification. After receiving the notification of the capping stop execution, the BIOS of the blade server stops the execution of the power capping according to the capping stop execution notification.

Step 314: The management board determines whether the current frame power consumption obtained by the current monitoring is less than or equal to a product of the preset interval lower limit coefficient and the whole frame power consumption capping value. If yes, step 315 is performed; otherwise, the process returns to step 308.

In this embodiment, the monitoring operation of the management board on the power consumption of the entire frame is not stopped due to the server power consumption monitoring of the BMC unit and the execution of the power consumption capping action, that is, in the process of performing the above steps 307-313, the management board The entire frame power consumption is still monitored at the same time. When one or several blade servers are served After the power consumption of the device is reduced, the power consumption of the entire frame will also decrease. In this step, the management board determines whether the power consumption of the entire frame obtained by the current monitoring is less than or equal to the preset interval lower limit coefficient and the entire frame power consumption capping value P. The product, if yes, proceeds to step 315, otherwise returns to step 308. The product of the interval lower limit coefficient and the entire frame power consumption capping value in this embodiment is the lower threshold of the resource pool shared by the blade server. For example, the interval lower limit coefficient may be set to 0.6, the interval upper limit coefficient and the entire frame power consumption cap value. The product is the upper threshold of the resource pool shared by the blade server, and the range between the upper threshold and the lower threshold constitutes the anti-shock interval of the resource pool. The anti-shock interval in this embodiment can be modified according to actual conditions. If the frequency of opening and closing the resource pool is high, the lower threshold can be appropriately lowered to increase the anti-shock interval.

Step 315: The management board starts the resource pool, and sends a power consumption capping stop instruction to each server, so that each server stops the power consumption capping control after receiving the power consumption capping stop instruction.

If the power consumption of the whole frame obtained by the current monitoring is greater than the product P of the preset interval lower limit coefficient and the entire frame power consumption capping value. ' 0.6 , the management board re-opens the resource pool and sends a power capping stop command to each server, so that each server stops the power capping control after receiving the power capping stop command, and completes one round of capping control. In this embodiment, the entire frame power consumption capping value P configured in the above step 301 is assumed. For 3500 watts, there are 10 in-plane blade servers in the chassis. The total power consumption of the fan, switch board, management board, power supply, etc. in the chassis is 500 watts, and the server power of each blade server is calculated. The consumption capping value P _m is 300 watts. At this time, the power consumption capping control method of the power consumption capping method of the present embodiment is used, and as the load is continuously increased, the power consumption variation result in the resource pool as shown in FIG. 5 can be obtained. FIG. 5 and FIG. 6 are respectively schematic diagrams showing changes in server power consumption and overall frame power consumption in the second embodiment of the power capping control method of the present invention. As can be seen from FIG. 5 and FIG. 6, the embodiment can implement resources. Maximize use. The control method of the power consumption capping provided in this embodiment may be applied to a blade server or a node server having a management board, and the status of the power consumption of the blade server is determined by the management board monitoring the running power of the entire frame in real time. The BMC unit of each blade server acts as the secondary switch of the blade server itself, and cooperates with the BIOS to perform the power capping action of the blade server itself, realizes the power capping flexible monitoring design, and limits the rated power consumption of the blade server to the power cap by power capping. The actual power consumption of the blade server can not only avoid the actual operation of the blade server. The waste of resources caused by 50% of rated power consumption can also greatly increase the density of equipment in the equipment room and machine rejection, and increase the utilization rate of space resources. In this embodiment, a shared resource pool is constructed by using a two-stage power capping switch, and the power capping is controlled by combining the whole frame power consumption and the server power consumption in the power capping process, and ensuring high in the case that the resource pool does not overflow. The load blade is running excessively, and the service performance is not affected. In the case of overflow of the resource pool, ensure that the power consumption of the entire frame does not exceed the preset power consumption capping value of the entire frame, thereby maximizing the power supply on the basis of ensuring power supply security. When the resource pool is opened, the power supply resource can be utilized to the maximum extent. When the resource pool is closed, the power supply of the entire rack blade system can be ensured. In this embodiment, the anti-shock interval of the resource pool is set by the upper and lower thresholds of the resource pool. The capping switch caused by the fluctuation of the business load is frequently turned on or off, which improves the stability of the power cap. In addition, in this embodiment, the management board monitors the power consumption of the fan, the power supply, the management board, and the switch board in real time, and adopts a scheme of real-time refreshing the server power consumption cap value of each blade server, thereby minimizing the power consumption capping. error. It will be understood by those skilled in the art that all or part of the steps of implementing the above method embodiments may be performed by hardware related to the program instructions. The aforementioned program can be stored in a computer readable storage medium. When the program is executed, the steps including the foregoing method embodiments are performed; and the foregoing storage medium includes: a medium that can store program codes, such as a ROM, a RAM, a magnetic disk, or an optical disk.
