Description
Technical Field
The invention belongs to the technical field of servers, and particularly relates to a server air inlet temperature correction method and system based on machine room backflow.
Background
The servers are placed in the machine room in batches, and heat generated by electric energy consumed by the servers is taken away by air conditioning equipment of the machine room; when an air supply channel of an air conditioner in the machine room is not well partitioned or the air supply capacity of the air conditioner is insufficient, high-temperature air flow heated by the server flows back to the positions of box lugs of the server from an air outlet through gaps among the machine cabinets; because the server places one or more temperature sensors that can respond to computer lab ambient temperature usually in the position of case ear, this Sensor has the backward flow to take place the back, is heated by the high temperature wind current of backward flow very easily, leads to the ambient temperature who senses very high, and under the general condition, the backward flow wind current temperature that Sensor sensed can be higher than the supply air temperature of air conditioner 20C, even higher. Because the server can adjust the fan according to the temperature Sensor: the higher the Sensor temperature, the higher the system fan speed. Therefore, when the Sensor is heated, the rotation speed of the fan of the server is easily increased, and the power consumption of the server is rapidly increased. And because the server actually still depends on the air conditioner to convey a large amount of cold air for refrigeration, the auxiliary heat dissipation of the fan rotating speed for lifting the server is not necessary, and as a result, the backflow causes great energy consumption waste, so that the temperature of the Sensor needs to be corrected to overcome the influence caused by the backflow.
The temperature Sensor of the front ear of the server can reflect the airflow temperature at the position of the front ear, but since the Sensor at the position of the front ear feeds back an electric signal, the temperature Sensor can manually correct the fed back temperature value, namely, the fed back value is increased or decreased by a fixed value, namely, a fixed offset. For example, when the air conditioner supply air temperature is 20C and the feedback causes the front ear Sensor display 40C, the feedback value of the front ear Sensor is set to be offset-20C, i.e., the display Sensor temperature 20C, and is consistent with the air conditioner supply air temperature.
However, the method can be customized for individual machine rooms with backflow, and because backflow conditions of different machine rooms are different, offsets are different, different offsets need to be set according to actual conditions of the machine rooms, the offset cannot be set before the server leaves the factory, and the universality is poor.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are merely for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows an implementation flowchart of a server inlet air temperature correction method based on machine room backflow, which specifically includes the following steps:
in step S101, a first temperature parameter T1 of a first temperature sensor at a front ear position of a server chassis and a second temperature parameter T2 of a second temperature sensor at a hard disk backplane position are read, where the second temperature sensor is used to detect a temperature of the hard disk backplane;
in this step, the second temperature sensor needs to be arranged at the position of the hard disk backplane in advance to provide a calculation basis for the following.
In step S102, it is determined whether a machine room backflow phenomenon exists in the current server, if yes, step S103 is executed, otherwise step S104 is executed;
in this step, there may be multiple implementation manners for determining the machine room backflow phenomenon, and one of them is given below and will not be described herein again.
In step S103, when it is determined that the current server has a machine room backflow phenomenon, recalculating the new inlet air temperature based on the pre-configured hard disk backplane temperature correction parameter and the read second temperature parameter T2 of the second temperature sensor disposed at the hard disk backplane, and using the recalculated new inlet air temperature as a control basis for controlling the rotational speed of the server fan;
in step S104, when it is determined that the current server does not have the machine room backflow phenomenon, the read first temperature parameter T1 of the first temperature sensor at the front ear position of the server chassis is used as the intake air temperature, and the first temperature parameter T1 is used as the control basis for controlling the rotation speed of the server fan.
In the embodiment of the present invention, as shown in fig. 2, the step of determining whether there is a machine room backflow in the current server specifically includes the following steps:
in step S201, it is determined whether the first temperature parameter T1 of the first temperature sensor at the front ear position of the server chassis is less than the second temperature parameter T2 of the second temperature sensor at the back panel position of the hard disk, if yes, step S202 is executed, otherwise step S203 is executed;
in step S202, when it is determined that the first temperature parameter T1 is less than the second temperature parameter T2, it is determined that the machine room backflow phenomenon does not exist in the current server;
in step S203, when it is determined that the first temperature parameter T1 is greater than or equal to the second temperature parameter T2, it is determined that the machine room backflow phenomenon exists at the current server.
The comparison between the first temperature parameter and the second temperature parameter is used as a basis for judgment, and other methods can be adopted.
In this embodiment, as shown in fig. 3, when it is determined that the current server has the machine room backflow phenomenon, the step of recalculating the new incoming air temperature based on the second temperature parameter T2 of the second temperature sensor disposed at the position of the hard disk backplane and based on the pre-configured hard disk backplane temperature correction parameter includes the following steps:
in step S301, when it is determined that the machine room backflow phenomenon exists in the current server, reading a pre-configured hard disk backplane temperature correction parameter;
in step S302, the obtained hard disk backplane temperature correction parameter and the second temperature parameter T2 are added to obtain the new inlet air temperature.
The following steps are also required to be executed before the step S301 is executed:
according to the load state of the hard disk backboard, configuring a hard disk backboard temperature correction parameter for a second temperature sensor arranged at the position of the hard disk backboard in advance, wherein the hard disk backboard temperature correction parameter is-2.5 ℃;
wherein, the second temperature sensor of hard disk backplate position is in the hard disk rear, and this second temperature sensor can lead to having certain deviation with air conditioner air supply temperature because of the load of hard disk backplate: when the hard disk is in no load, the second temperature parameter of the second temperature sensor is 1 degree higher than the air supply temperature, and when the hard disk is in high load, the second temperature parameter of the second temperature sensor is 4 degrees higher than the air supply temperature; because the load state of the hard disk is not well judged, the offset of minus 2.5 ℃ can be uniformly added to the temperature Sensor of the hard disk backboard for processing, so that the deviation of +/-1.5 ℃ can be generated when the temperature of the hard disk backboard after the offset is used for replacing the air inlet temperature, the error can be generally accepted (the error is much better than that of 20 ℃ or even more when the air inlet temperature Sensor is used), and the system after the backflow is generated is solved.
