Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The public version design of the domestic CPU is simpler, a specific algorithm related to power control is not available, and the problem of power capping function deficiency exists. According to the method and the device, the current target level is determined through the comparison relation between the power capping target value and the current power consumption value of the whole machine, and the effect of adjusting the power consumption value of the whole machine is achieved by utilizing the characteristic that an Operating System (OS) operates according to the target level. According to the scheme, the power capping of the server is realized through dynamic adjustment, the method is simple and quick, and the adjusting efficiency is high.
The embodiment of the invention discloses a power capping method of a server, which is shown in fig. 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 overall power consumption value of a server;
s3: and comparing the power capping target value with the current overall power consumption value, and determining the current target level in the p-state table so that the operating system OS adjusts the current overall power consumption value according to the current target level.
It will be appreciated that the execution body of this embodiment is typically a BMC, where the client instruction is specifically a power policy, including a power capping target value, and the current overall power consumption value of the server is typically sent to the BMC by the PSU through the PMBUS.
It can be understood that the p-state table contains a plurality of power levels, and the higher the power level is, the larger the corresponding power values at the two ends of the power meter are. The CPU can select a certain power level in the p-state table as a target level, and based on the working characteristics of the 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, the step S2 of obtaining the current power consumption value of the whole machine of the server, including obtaining the current power consumption value of the whole machine of the server according to the preset frequency, and then executing step S3 after step S2, wherein 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 can reach the effect of approximating the power capping target value.
The embodiment of the application discloses a power capping method of a server, which comprises the following steps: acquiring a power capping target value through a client instruction; acquiring a current overall power consumption value of a server; and comparing the power capping target value with the current overall power consumption value, and determining the current target level in the p-state table so that the operating system OS adjusts the current overall power consumption value according to the current target level. According to the method and the device, the current target level is determined through the comparison relation between the power capping target value and the current power consumption value of the whole machine, and the effect of adjusting the power consumption value of the whole machine is achieved by utilizing the characteristic that an Operating System (OS) operates according to the target level. According to the scheme, the power capping of the server is realized through dynamic adjustment, the method is simple and quick, and the adjusting efficiency is high.
The embodiment of the invention discloses a specific power capping method of a server, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme.
Specifically, the process of comparing the power capping target value with the current overall power consumption value to determine the current target level in the p-state table includes:
comparing the power capping target value with the current power consumption value of the whole machine;
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 lowered by one level;
the higher the power level in the p-state table, the larger the corresponding power value at both ends of the power level.
Further, if the current power consumption value of the complete machine is smaller than the power capping target value, the process of raising the current target level in the p-state table by one level includes:
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 adjust the current target level in the p-state table by one level;
correspondingly, if the current power consumption value of the whole machine is larger than the power capping target value, the process of reducing the current target level by one level 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.
Typically, the first signal terminal and the second signal terminal are GPIO signal terminals.
That is, in this embodiment, two paths exist between the BMC and the CPU, and when the target level is to be adjusted up, a first level adjustment signal is sent to the CPU through a first signal terminal, the current target level of the p-state table in the CPU is adjusted up by one level, and when the target level is to be adjusted down, a second level adjustment signal is sent to the CPU through a second signal terminal, and the current target level of the p-state table in the CPU is adjusted down by one level. The adjustment adopts simpler judgment basis and adjustment mode, the process is quick, but the adjustment cannot be performed once, and the ideal effect can be achieved through multiple times of adjustment.
The embodiment of the invention discloses a specific power capping method of a server, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme.
Specifically, the process of comparing the power capping target value with the current overall power consumption value to determine the current target level in the p-state table includes:
the power capping target value and the current power consumption value of the whole machine are subjected to difference;
determining the number of stages to be adjusted and the direction to be adjusted according to the difference value;
and adjusting the current target level in the p-state table according to the number of levels to be adjusted and the direction to be adjusted.
It can be understood that the actions of determining the number of levels to be adjusted, the direction to be adjusted and adjusting the current target level in this embodiment may be implemented by the BMC entirely, only by sending an instruction for updating the current target level to the CPU, or may be implemented entirely by the CPU, that is, by comparing the power capping target value with the current overall power consumption value by the CPU, determining the current target level in the p-state table, or may be implemented partially by the BMC, and partially by the CPU, where the specific execution body allocation may be determined according to the processing capacities and the communication cheapness of the BMC and the CPU.
