Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The public version design of the domestic CPU is simple, a specific algorithm related to power control is not provided, and the problem of power capping function loss exists. The method and the device determine the current target level through the comparison relationship between the power capping target value and the current power consumption value of the whole machine, and achieve the effect of adjusting the power consumption value of the whole machine by utilizing the characteristic that the operating system OS operates according to the target level. The scheme realizes the power capping of the server through dynamic adjustment, and the method is simple and rapid and has high adjusting efficiency.
The embodiment of the invention discloses a power capping method of a server, which is shown in a figure 1 and comprises the following steps:
s1: acquiring a power capping target value through a client instruction;
that is, the power capping target value does not change frequently, and is updated only when a client command is received.
S2: acquiring a current complete machine power consumption value of a server;
s3: and comparing the power capping target value with the current complete machine power consumption value, and determining the current target level in the p-state table so that the operating system OS adjusts the current complete machine power consumption value according to the current target level.
It is understood that the execution subject of this embodiment is typically BMC, wherein the client instruction is specifically power policy, which includes the power capping target value, and the current overall power consumption value of the server is typically sent to BMC by PSU through PMBUS.
It can be understood that the p-state table comprises a plurality of power levels, and the higher the number of the power levels is, the larger the corresponding power value at the two ends of the power meter is. A certain power level in a p-state table can be selected as a target level in the CPU, and based on the working characteristics of an Operating System (OS), the OS can adjust the overall power consumption of the server according to the target level. If the power capping target value is not the upper limit value of the target level, the adjusted power consumption value of the whole machine still does not correspond to the power capping target value, and in general, the BMC continuously executes steps S1-S3 of the power capping method, especially step S2, and the process of obtaining the current power consumption value of the whole machine of the server includes obtaining the current power consumption value of the whole machine of the server according to a preset frequency, and step S3 is executed after step S2, where the power consumption value of the whole machine of the server is in dynamic fluctuation in the whole adjustment process, and the average power consumption of the server can achieve the effect of approximating the power capping target value.
The embodiment of the application discloses a power capping method for a server, which comprises the following steps: acquiring a power capping target value through a client instruction; acquiring a current complete machine power consumption value of a server; and comparing the power capping target value with the current complete machine power consumption value, and determining the current target level in the p-state table so that the operating system OS adjusts the current complete machine power consumption value according to the current target level. The method and the device determine the current target level through the comparison relationship between the power capping target value and the current power consumption value of the whole machine, and achieve the effect of adjusting the power consumption value of the whole machine by utilizing the characteristic that the operating system OS operates according to the target level. The scheme realizes the power capping of the server through dynamic adjustment, and the method is simple and rapid and has high adjusting efficiency.
The embodiment of the invention discloses a specific power capping method for a server, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme.
Specifically, the process of comparing the power capping target value with the current power consumption value of the whole machine and determining the current target level in the p-state table includes:
comparing the power capping target value with the current complete machine power consumption value;
if the current power consumption value of the whole machine is smaller than the power capping target value, the current target level in the p-state table is increased by one level;
if the current power consumption value of the whole machine is larger than the power capping target value, the current target level is reduced by one level;
wherein, the higher the power level number in the p-state table is, the larger the power value corresponding to the two ends of the power level is.
Furthermore, if the current power consumption value of the whole machine is smaller than the power capping target value, the process of increasing the current target level in the p-state table by one level comprises the following steps:
if the current power consumption value of the whole machine is smaller than the power capping target value, a first level adjusting signal is sent to the CPU through a first signal end so as to increase the current target level in the p-state table by one level;
correspondingly, if the current power consumption value of the whole machine is greater than the power capping target value, the current target level is reduced by one level, and the process comprises the following steps:
and if the current power consumption value of the whole machine is larger than the power capping target value, sending a second level adjusting signal to the CPU through a second signal end so as to lower the current target level by one level.
Generally, the first signal terminal and the second signal terminal are both GPIO signal terminals.
That is to say, the embodiment is still executed by the BMC, two paths exist between the BMC and the CPU, when the target level is to be adjusted higher, the first signal end sends the first level adjustment signal to the CPU, and the current target level of the p-state table in the CPU is adjusted higher by one level, and when the target level is to be adjusted lower, the second signal end sends the second level adjustment signal to the CPU, and the current target level of the p-state table in the CPU is adjusted lower by one level. The adjustment adopts simpler judgment basis and adjustment mode, the process is quick, but the adjustment can not be carried out at one time, and the ideal effect can be achieved only by multiple times of adjustment.
The embodiment of the invention discloses a specific power capping method for a server, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme.
Specifically, the process of comparing the power capping target value with the current power consumption value of the whole machine and determining the current target level in the p-state table includes:
calculating the difference between the power capping target value and the current complete machine power consumption value;
determining the number of stages to be adjusted and the direction to be adjusted according to the difference;
and adjusting the current target level in the p-state table according to the number of the levels to be adjusted and the direction to be adjusted.
It can be understood that, in this embodiment, the actions of determining the number of stages to be tuned, the direction to be tuned, and adjusting the current target stage may be all implemented by the BMC, and only an instruction for updating the current target stage is sent to the CPU, or all implemented by the CPU, that is, the CPU compares the power capping target value with the current power consumption value of the overall device, and determines the current target stage in the p-state table, or may be partially implemented by the BMC, or partially implemented by the CPU, and the specific execution main body allocation may be determined according to the processing capability and the communication cheapness of the BMC and the CPU.
