Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a method for determining an inlet air temperature of a server according to an embodiment of the present invention. The present embodiment is applicable to a case where the temperature of the incoming wind of the server is estimated from the temperature measured inside the server. The method of the embodiment may be performed by a device for determining the inlet air temperature of the server, which may be implemented by software and/or hardware, and may be configured in the server.

Correspondingly, the method specifically comprises the following steps:

and S110, acquiring real-time measured temperature of the heat source separation area in the server.

Wherein, the heat source separation area may be an area separated from the heat generating device in the server. The real-time measured temperature may be a measured temperature obtained by measuring a temperature in a heat source separated region of the server.

Optionally, the obtaining of the real-time measured temperature of the heat source separation area in the server may include: acquiring a plurality of temperature measurement values through at least two temperature sensors arranged on a front hard disk back plate in a server; and calculating the real-time measured temperature of the heat source separation area according to the plurality of temperature measured values.

The front hard disk backplane can be a hard disk backplane connected with an array card built in the server, and can determine the number of the supported hard disks of the server. The temperature sensor can be a sensor which can sense temperature and convert the temperature into a usable output signal, the temperature sensor is a core part of a temperature measuring instrument, the temperature sensor has various varieties, can be divided into two types of contact and non-contact according to a measuring mode, and is divided into two types of thermal resistance and thermocouple according to the characteristics of sensor materials and electronic elements.

In the process of implementing the invention, the inventor finds that the installation position of the front hard disk backboard in the server is far away from each heating device (typically, a central processing unit) in the server and has a certain heat insulation function, so that the area where the front hard disk backboard is located is selected and determined as the heat source separation area in the server, and the air inlet temperature of the server is estimated by uniformly arranging a plurality of temperature measurement values on the front hard disk backboard and respectively collecting a plurality of temperature measurement values.

Specifically, according to a plurality of temperature measurement values, a weighted averaging method can be adopted to calculate more accurate temperature measurement values, so as to further calculate and obtain the real-time measured temperature of the heat source separation area.

The advantages of such an arrangement are: through setting up temperature sensor on the inside leading hard disk backplate of server, both can avoid the influence of backward flow phenomenon to the test result, also can the at utmost separation device that generates heat in the server to the influence of measuring result for measuring result can be the biggest actual temperature of entering the wind of approaching the server. Meanwhile, the accuracy of the measurement result can be further improved by jointly determining the real-time measurement temperature by using the temperature measurement values of the plurality of temperature sensors.

Of course, it is understood that, besides obtaining the real-time measured temperature by weighted summation of a plurality of temperature measurement values measured by a plurality of temperature sensors, the real-time measured temperature may also be directly measured by only one temperature sensor, which is not limited in this embodiment.

And S120, acquiring a target air inlet temperature correction parameter matched with the server according to the hardware layout in the heat source separation area.

The hardware layout may be a specific layout situation of a hardware structure in a heat source separation area of the server. The target inlet air temperature correction parameter may be a value for correcting the obtained real-time measured temperature.

It can be understood that, although the temperature sensor is disposed on the front hard disk backplane in the server, the temperature sensor is a measured temperature collected and obtained inside the server, theoretically, the real-time measured temperature value is certainly higher than the actual air inlet temperature outside the server, and therefore, the real-time measured temperature value can be adjusted by using a preset negative correction parameter, so that the corrected measured temperature correction value is closer to the actual air inlet temperature of the server.

Optionally, the obtaining a target inlet air temperature correction parameter matched with the server according to the hardware layout in the heat source separation region may include: inquiring the quantity of target front hard disk backplanes included in the server from the BMC in the server; and inquiring the mapping relation between the preset number of the front hard disk back plates and the inlet air temperature correction parameters, and acquiring the target inlet air temperature correction parameters matched with the target number of the front hard disk back plates.

The BMC is a baseboard management controller, and can perform operations such as firmware upgrading on the machine and checking of machine equipment in a state that the machine is not started, specifically, the operations include querying the number of target front hard disk backplanes included in the server.

Illustratively, the server issues an instruction to the BMC in the server to query the number of target front hard disk backplanes included in the server, because the number of different front hard disk backplanes corresponds to different air inlet temperature correction parameters. Specifically, when the number of the target front hard disk backplates is 3, the inlet air temperature correction parameter can be set to-6 ℃. Further, when the number of the target front hard disk back plates is 2, the air inlet temperature correction parameter can be set to be-5 ℃; when the number of the target front hard disk back plates is 1, the inlet air temperature correction parameter can be set to be-3 ℃. Correspondingly, a mapping relation is formed between the number of the front hard disk back plates and the inlet air temperature correction parameters, so that the target inlet air temperature correction parameters matched with the number of the target front hard disk back plates can be obtained.

The advantages of such an arrangement are: the real-time measured temperature is corrected by selecting the matched inlet air temperature correction parameters according to the number of the front hard disk back plates actually included in the server, and the more accurate inlet air temperature of the server can be calculated according to the actual hardware configuration environment of the temperature sensor.

And S130, calculating a measurement temperature correction value according to the real-time measurement temperature and the target inlet air temperature correction parameter, and estimating the inlet air temperature of the server by using the measurement temperature correction value.

The measured temperature correction value may be a specific correction value for adjusting the target inlet air temperature. The air inlet temperature of the server can be used for monitoring the ambient temperature of the server in real time during operation, and the air inlet temperature is monitored by the mainboard at a position close to an air inlet.

Specifically, the inlet air temperature correction parameter is determined according to the actual measured temperature obtained by measurement and the number of the front hard disk backplanes, and the measured temperature correction value can be further calculated. Accordingly, the inlet air temperature of the server can be estimated according to the calculated measured temperature correction value.

For example, assuming that the real-time measured temperature of the heat source partition area in the server is 36 ℃, and assuming that the number of target front hard disk backplanes is 2, the inlet air temperature correction parameter of the corresponding method is-5 ℃, and further, the measured temperature correction value may be calculated to be 36 ℃ (+ (-5 ℃), 31 ℃. Accordingly, the measured temperature correction value may be used to estimate the incoming air temperature of the server to be 31 ℃.

Optionally, after calculating a measured temperature correction value according to the real-time measured temperature and the target inlet air temperature correction parameter, and estimating the inlet air temperature of the server using the measured temperature correction value, the method further includes: if the measured temperature correction value is determined to be greater than or equal to a preset first threshold value threshold, generating temperature adjustment prompt information to indicate that the temperature of the environment where the server is located is reduced, or if the measured temperature correction value is determined to be greater than or equal to a preset second threshold value threshold, generating abnormal temperature early warning information.

The first threshold may be a threshold of a first temperature correction value set by the server, and when the measured temperature correction value exceeds the preset first threshold, temperature adjustment prompt information may be generated to prompt to reduce the temperature of the environment where the server is located. Correspondingly, the second threshold may be a second temperature correction value threshold set by the server, and when the measured temperature correction value exceeds the preset second threshold, the abnormal temperature early warning information is generated.

In the previous example, the calculated measured temperature correction value is 32 ℃, and the server is assumed to set the first threshold value as 30 ℃ and the second threshold value as 40 ℃. Since the measured temperature correction value is greater than or equal to the preset first threshold, that is, 32 ℃ is greater than 30 ℃, the temperature adjustment prompt message may be generated to instruct to reduce the temperature of the environment where the server is located.

The advantages of such an arrangement are: the server sets a first threshold and a second threshold, and compares the measured temperature correction value with the set first threshold and the set second threshold to adjust the temperature of the corresponding environment or perform abnormal temperature early warning operation. The computer room system can be controlled to accurately control the temperature, accurate alarm information is efficiently provided for relevant workers, the processing efficiency is improved, and the maintenance cost of the computer room is reduced.

Example two

Fig. 2 is a flowchart of a method for determining an air inlet temperature of a server according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and in the present embodiment, the operation of establishing the mapping relationship between the number of front hard disk backplates and the inlet air temperature correction parameter is embodied.

Correspondingly, the method specifically comprises the following steps:

s210, obtaining a test server, wherein the test server comprises a target number of front hard disk backplanes.

In this embodiment, a plurality of test servers with different numbers of front hard disk backplates can be used to respectively determine the matched intake air temperature correction parameters, and then a mapping relationship between the number of front hard disk backplates and the intake air temperature correction parameters can be established.

That is, for the test server including the number of the N front hard disk backplates, a matched inlet air temperature correction parameter a can be calculated, and then a mapping relationship between the inlet air temperature correction parameter a and the number N of the front hard disk backplates can be established.

S220, obtaining the environment temperature curves of the test server in different working environments and the real-time measurement temperature curves of the heat source separation areas in the test server, and determining the adjustment range of the correction coefficient according to the environment temperature curves and the real-time measurement temperature curves.

The environment temperature curve may be an environment temperature curve formed by measuring the environment temperatures of the test server at different time points in a set working environment. The real-time measured temperature curve may be a real-time measured temperature curve formed by measuring real-time measured temperature values of the heat source separation area in the server at different time points in a set working environment.

The correction coefficient adjustment range may be a range size within which the correction coefficient can be adjusted, the correction coefficient adjustment range is used to limit a value range selectable by each of the inlet temperature correction parameters, if the correction coefficient adjustment range is too large, the calculation amount of subsequently selected inlet temperature correction parameters is increased, and if the correction coefficient adjustment range is too small, the most appropriate inlet temperature correction parameter may be left. Therefore, the correction coefficient adjustment range needs to be selected appropriately.

Optionally, the obtaining the environmental temperature curves of the test server in different working environments and the real-time measured temperature curve of the heat source separation area in the test server, and determining the adjustment range of the correction coefficient according to each of the environmental temperature curves and the real-time measured temperature curve may include:

acquiring a first target environment temperature curve and a first target real-time measurement temperature curve of the test server in a limit working environment; calculating a first maximum temperature difference value matched with the limit working environment according to the first target environment temperature curve and a first target real-time measurement temperature curve; acquiring a second target environment temperature curve and a second target real-time measurement temperature curve of the test server under a plurality of common working environments; calculating a second maximum temperature difference value respectively matched with each common working environment according to each second target environment temperature curve and a second target real-time measurement temperature curve; and determining the adjustment range of the correction coefficient according to the first maximum temperature difference and each second maximum temperature difference.

The limit working environment may be a working environment in which the server is in the lowest temperature environment and the front hard disk backplane is in a full load state. The first target ambient temperature curve may be an ambient temperature curve formed by measuring ambient temperatures of the test server at different time points in the extreme operating environment. The first target real-time measured temperature curve may be a real-time measured temperature curve formed by real-time measured temperature values of the heat source separation region at different time points in the measurement server in the extreme working environment. The first maximum temperature difference may be a maximum temperature difference among a plurality of temperature differences obtained by respectively subtracting the ambient temperature and the real-time measured temperature value at the same time point according to the first target ambient temperature curve and the first target real-time measured temperature curve.

Further, the common working environment may be that the test server is in a non-limit working environment, that is, the test server is in a normal working temperature range, and the server is in any one of an idle state, a state where the front hard disk backplane is in a full load state, or a state where the server is in a full load state.

Specifically, assuming that the temperature range of the server room is 20 ℃ to 30 ℃, the temperature environment selected from the extreme working environment is 20 ℃, and further, a gradient may be set at 5 ℃, and 25 ℃ and 30 ℃ are respectively selected as the temperature environments in the ordinary working environment.

The second target ambient temperature curve may be an ambient temperature curve formed by measuring ambient temperatures of the test server at different time points in a normal working environment. The second target real-time measured temperature curve may be a real-time measured temperature curve formed by real-time measured temperature values of the heat source separation region at different time points in the measurement server in a common working environment. The second maximum temperature difference may be a maximum temperature difference among a plurality of temperature differences obtained by respectively subtracting the ambient temperature and the real-time measured temperature value at the same time point according to the second target ambient temperature curve and the second target real-time measured temperature curve.

If the second target environment temperature curve and the second target real-time measurement temperature curve respectively corresponding to the two common working environments are obtained through calculation, two second maximum temperature difference values respectively corresponding to the two common working environments can be calculated, and then the second maximum temperature difference value which is farthest away from the first maximum temperature difference value in the two second maximum temperature difference values and the first maximum temperature difference value jointly form the correction coefficient adjustment range.

In one specific example, if the first maximum temperature difference is-5 deg.C, the two second maximum temperature differences are-2 deg.C and-3 deg.C, respectively. Then [ -2 ℃, -5 ℃ ] can be selected as the correction factor adjustment range.

In this embodiment, the test server measures the corresponding ambient temperature curve and the real-time measured temperature curve of the heat source separation area in the test server in the extreme working environment and the normal working environment. The first target environment temperature curve, the first target real-time measurement temperature curve, the second target environment temperature curve and the second target real-time measurement temperature curve can be obtained, and the first maximum temperature difference value and the second maximum temperature difference value are further calculated to further determine the adjustment range of the correction coefficient.

The advantages of such an arrangement are: corresponding ambient temperature curves and real-time measurement temperature curves can be obtained according to the test server under different working environments, so that the adjustment range of the correction coefficient is determined, the calculated adjustment range of the correction coefficient can be more accurate, and the inlet air temperature correction parameters meeting the temperature correction conditions more reasonably can be obtained.

Optionally, the limit working environment is that the test server is in the lowest temperature environment, and the front hard disk backplane is in a full load state; the common working environment is that the test server is in a normal working temperature range, and the server is in any one of an idle state, a front hard disk backboard is in a full load state or the server is in a full load state.

In this embodiment, the limit operating environment of the test server refers to being in the lowest temperature environment, and the front hard disk backplane is in a full load state. Specifically, the minimum temperature environment may be a minimum ambient temperature required for the test server to be able to operate normally. The front hard disk backboard is in a full load state, which means that the test server works in a state of being capable of supporting the maximum number of hard disks. The server is in a full load state, which means that the test server is in a maximum allowed memory running state.

The advantages of such an arrangement are: the environment temperature curve and the real-time measurement temperature curve are further measured by enabling the test server to be in the limit working environment and the common working environment, so that the adjustment range of the calculated correction coefficient can be more accurate, the invalid calculation workload caused by the fact that the adjustment range of the correction coefficient is too large is avoided, and the most suitable inlet air temperature correction parameter cannot be effectively selected when the adjustment range of the correction coefficient is too small is also prevented.

And S230, searching to obtain an inlet air temperature correction parameter meeting a temperature correction condition in the correction coefficient adjustment range according to a difference curve between each environment temperature change curve and the real-time measurement temperature change curve.

The difference curve can be obtained by subtracting the ambient temperature change curve from the real-time measured temperature change curve.

respectively acquiring inlet air temperature correction parameters in a preset incremental step within the correction coefficient adjustment range, and verifying whether a correction result curve is within a preset fluctuation allowable range after the difference curve is corrected by using each inlet air temperature correction parameter; calculating the curve area of the lower half shaft of the X axis corresponding to the correction result curve of each inlet temperature correction parameter aiming at each inlet temperature correction parameter of which the correction result is in the fluctuation allowable range; and determining the inlet air temperature correction parameter with the maximum area of the X-axis lower half shaft curve as the inlet air temperature correction parameter meeting the temperature correction condition.

The preset increment step length may be a corresponding value, and the preset increment step length is used as a step length value and gradually increased. And obtaining corresponding inlet air temperature correction parameters within the correction coefficient adjustment range. The correction result curve can be a curve obtained after the difference curve is corrected by the inlet air temperature correction parameter. The X-axis lower semi-axis curve area may be an area of each closed region of the correction result curve composed of the X-axis lower semi-axis curve and the X-axis. The fluctuation allowable range may be a preset error allowable interval, and for example, the fluctuation allowable range may be ± 1 ℃, or ± 0.5 ℃, or the like.

For example, assuming that the adjustment range of the correction coefficient is [ -5 ℃, -3 ℃ ], and assuming that the preset incremental step is 0.5 ℃, the correction parameters of the inlet air temperature are respectively-5 ℃, -4.5 ℃, -4 ℃, -3.5 ℃ and-3 ℃, after the difference curve is corrected by using the correction parameters of the inlet air temperature, a corresponding correction result curve can be obtained, and whether the correction result curve is within the preset allowable fluctuation range is determined. And assuming that the inlet air temperature correction parameters are-5 ℃, 4.5 ℃ and-4 ℃, the corresponding correction results are all in the fluctuation allowable range. Therefore, the area of the lower half-axis curve of the X axis corresponding to the correction result curve of each intake temperature correction parameter is calculated, the calculated curve areas are assumed to be 2, 1 and 3 respectively, and further, the intake temperature correction parameter with the maximum area of the lower half-axis curve of the X axis is-4 ℃, which is determined as the intake temperature correction parameter meeting the temperature correction condition.

The advantages of such an arrangement are: after determining each inlet air temperature correction parameter meeting the fluctuation allowable range, further selecting one inlet air temperature correction parameter which enables the corrected measured temperature correction value to be lower than the maximum probability of the inlet air temperature of the server, and through the operation, the probability that the finally estimated inlet air temperature of the server is higher than the actual inlet air temperature is the lowest, so that the situations of error adjustment or false alarm and the like of the temperature of the machine room caused by inaccuracy of the estimated value can be reduced to the maximum extent, the energy consumption of the machine room can be further reduced, and the operation cost is saved.

And S240, establishing a mapping relation between the searched inlet air temperature correction parameters and the target quantity.

Exemplarily, assuming that a test server is obtained, and the test server is respectively in an extreme working environment and a common working environment, a corresponding ambient temperature curve and a real-time measured temperature curve can be obtained according to measurement, so as to determine a correction coefficient adjustment range, assuming that the determined correction coefficient adjustment range is [ -5 ℃ and-3 ℃, assuming that a preset increment step is 0.5 ℃, then the inlet air temperature correction parameters are respectively-5 ℃, 4.5 ℃, 4 ℃, 3.5 ℃ and-3 ℃, after the difference curve is corrected by respectively using the inlet air temperature correction parameters, a corresponding correction result curve can be obtained, and whether the correction result curve is in a preset fluctuation allowable range is judged. And assuming that the inlet air temperature correction parameters are-5 ℃, 4.5 ℃ and-4 ℃, the corresponding correction results are all in the fluctuation allowable range. Therefore, the area of the lower half-axis curve of the X axis corresponding to the correction result curve of each intake temperature correction parameter is calculated, and assuming that the calculated curve areas are 2, 1 and 3 respectively, further, the intake temperature correction parameter with the maximum area of the lower half-axis curve of the X axis is-4 ℃, and is determined as the intake temperature correction parameter meeting the temperature correction condition, so that the mapping relation between the intake temperature correction parameter and the target quantity can be determined.

Further, the measured temperature correction value may be calculated to be 36 ℃ + (-5 ℃) ═ 31 ℃. Accordingly, the measured temperature correction value may be used to estimate the incoming air temperature of the server to be 31 ℃.

Accordingly, the calculated measured temperature correction value is 31 ℃, and the server is assumed to set the first threshold value as 30 ℃ and the second threshold value as 40 ℃. Since the measured temperature correction value is greater than or equal to the preset first threshold, that is, 31 ℃ is greater than 30 ℃, the temperature adjustment prompt message may be generated to instruct to reduce the temperature of the environment where the server is located.
