Description
Technical Field
The application relates to the field of servers, in particular to a method, a system, equipment and a storage medium for detecting whether screws of a CPU radiator are missed to be screwed.
Background
The server is used as a computer to provide services such as calculation, storage, data exchange and the like for internet users, and is an important constituent node in the internet era. The server has higher operation speed, longer operation time, larger data throughput, larger power consumption and heat brought in the operation process than those of a household PC (Personal Computer ), the high temperature is the death enemy of an integrated circuit, the high temperature not only can lead to unstable system and shortened service life, but also can lead to circuit burnout when serious; heat dissipation is a development difficulty that must be overcome in the server design process. The good heat dissipation scheme ensures the efficient and stable operation of the server on one hand, and can greatly reduce the operation cost of the data center on the other hand.
At present, three heat dissipation modes are common in the industry: 1) heat dissipation by a radiator, 2) air cooling heat dissipation, and 3) liquid cooling heat dissipation. The radiator mainly radiates heat in a heat conduction mode, radiating fins are fixed at parts with serious heat generation, and heat is transferred in the process of substance-to-substance contact, such as radiating fins of a CPU; the air cooling heat dissipation is to add a fan, and heat is taken out of the machine in one direction by accelerating air flow; the liquid cooling heat dissipation is to absorb heat through liquid cooling liquid and flow out. The heat dissipation scheme combining air cooling heat dissipation and radiator heat dissipation is common.
A CPU is used as a main heating device in the server; it is generally necessary to mount a heat sink on the CPU; taking an Inter X86 server as an example: the CPU is required to be mounted on the radiator, then the CPU and the radiator are mounted on a CPU Socket (Socket), and then a nut on the radiator is required to be screwed down, so that the CPU is fastened on the CPU Socket.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the following embodiments of the present application will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present application, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present application, and the following embodiments are not described one by one.
In a first aspect of the embodiment of the application, an embodiment of a method for detecting whether screws of a CPU radiator are missed is provided. Fig. 1 is a schematic diagram of an embodiment of a method for detecting whether screws of a CPU radiator are missed. As shown in fig. 1, the embodiment of the present application includes the following steps:
s1, responding to the detection of the starting abnormality of a server by a baseboard management controller, sending an enabling signal to a voltage regulator chip, so that the voltage regulator chip supplies power for a two-wire synchronous serial bus exchange chip and all pressure sensors arranged on a CPU socket stud;
s2, sequentially acquiring a pressure value of each pressure sensor through a two-wire synchronous serial bus signal, and comparing the acquired pressure value with a threshold value; and
and S3, positioning the pressure sensor and recording a screw number corresponding to the pressure sensor into a log in response to the fact that the pressure value of the pressure sensor does not accord with the threshold value.
Fig. 2 is a schematic diagram of a CPU socket in an embodiment of the present application, as shown in fig. 2, a socket body is disposed below, and the socket body contacts with a CPU through PIN PINs, and four corners are respectively provided with 4 studs. Under normal conditions, the CPU is buckled on the socket, and then the nut on the radiator is screwed. On the basis, a pressure sensor is required to be arranged at the upper end of each stud; and when the nut is continuously screwed down, certain pressure is caused to the pressure sensor at the top end of the stud. Meanwhile, a cable for supplying power to the sensor and transmitting signals is arranged in the stud; can be directly connected to the PCB (Printed circuit board ).
Fig. 3 is a schematic diagram of a two-path server BMC monitoring pressure sensor provided by the present application, as shown in fig. 3, each CPU has 4 studs, and each stud has a pressure sensor thereon. Taking two servers as an example, there are 8 pressure sensors in total. Each pressure sensor has an I2C (two-wire synchronous serial bus) signal. Each pressure sensor is connected to an I2C switch chip, for example PCA9548, and the final BMC accesses the I2C switch chip via one I2C and polls each pressure sensor.
And in response to the detection of the abnormal starting of the server by the baseboard management controller, sending an enabling signal to the voltage regulator chip, so that the voltage regulator chip supplies power for the two-wire synchronous serial bus exchange chip and all the pressure sensors arranged on the CPU socket studs. When the BMC detects that the server is started or other abnormal conditions, the VR chip sends an Enable signal to Enable the VR chip to supply power for the I2CSwitch chip and all the pressure sensors.
And sequentially acquiring the pressure value of each pressure sensor through a two-wire synchronous serial bus signal, and comparing the acquired pressure value with a threshold value. The BMC polls the information of each pressure sensor through the I2C signal, acquires the pressure value of each pressure sensor, and compares the pressure value with a set threshold value.
And in response to the fact that the pressure value of the pressure sensor does not meet the threshold value, positioning the pressure sensor and recording the screw number corresponding to the pressure sensor into a log. If the set threshold is not met, the CPU screw is not screwed or not screwed, and the information is recorded in the BMC log, so that the CPU installation problem can be directly judged. The threshold value here may be a section in which the pressure value corresponds to the threshold value.
In some embodiments, the method further comprises: and in response to the pressure values of all the pressure sensors meeting the threshold value, pulling down an enabling signal of the voltage regulator chip to disconnect power supply to the two-wire synchronous serial bus exchange chip and all the pressure sensors arranged on the CPU socket studs. When the pressure values read by all the sensors accord with the set threshold, the BMC pulls down the Enable signal of VR; power is removed to the pressure sensor and the I2C Switch chip.
In some embodiments, the method further comprises: checking the pressure values of the pressure sensors in groups, and determining whether the maximum difference value of the pressure values of each CPU corresponding group is larger than a second threshold value; and in response to the maximum difference between the pressure values of the corresponding groups of CPUs being greater than a second threshold, locating the CPUs and alerting. If the pressure value difference of the four pressure sensors in one group is too large, the stress of the CPU is uneven, and the CPU is easy to damage, so that the values of the four pressure sensors in each group can be checked and the maximum difference value can be determined. The maximum difference is the difference between the maximum value and the minimum value, and if the maximum difference is larger than the second threshold value, an alarm is given.
In some embodiments, the method further comprises: the threshold is adjusted in response to there being pressure values for all pressure sensors within the corresponding set of CPUs that do not meet the threshold and are all non-zero. If none of the pressure values of the four pressure sensors in a group meets the threshold value, which may be that none of the four studs is screwed or not screwed, the threshold value may be adjusted appropriately if the situation that none of the four studs is screwed or not screwed is excluded.
It should be noted that, in the embodiments of the method for detecting whether the screws of the CPU radiator are unscrewed, the steps may be intersected, replaced, added and subtracted, so that the method for detecting whether the screws of the CPU radiator are unscrewed by the reasonable permutation and combination is also within the protection scope of the present application, and the protection scope of the present application should not be limited to the embodiments.
