Description
Technical Field
The field relates to the field of computers, and more particularly to a method and apparatus for server pre-heating.
Background
When the server gradually develops to the edge field, considering that the edge environment is worse than the data center room, the edge server may be arranged in the edge room, the corridor environment, or even the outdoor environment, the low-temperature working range of the server may be expanded to below 0 degrees, the lower limit of the working temperature of the ordinary server is 5 degrees, the lower limit of the working temperature of the ordinary commercial-grade device is 0 degrees, and the server is not suitable for the edge working scene below 0 degrees. If the device supporting the working temperature below 0 ℃ is directly selected, the cost of the server is obviously increased, and the requirement of low cost of the edge scene is not met.
The conventional computer CPU related preheating techniques mainly include the following two techniques:
the CPU body preheating scheme starts the CPU main system after low-temperature startup, but does not run a working load, the CPU main system can naturally dissipate heat to bring temperature rise in the server case, and the server is integrally restarted after the temperature in the standby box rises above a threshold temperature, so that the last restarting temperature of the server is ensured to be above the threshold temperature. The disadvantage is that it is not ensured that the CPU and the peripheral devices operate at 0 degree or above at any time, and when the CPU and the peripheral devices are started at 0 degree or below, uncontrollable operations such as abnormal starting and data rewriting may occur with low probability, resulting in system starting failure or abnormal rewriting of data such as CMOS or BIOS. The probability is low, and may be related to factors such as manufacturer lot of devices, and the like, and is difficult to eradicate once a fault occurs.
According to the heating sheet preheating scheme, after the system is started at a low temperature, a CPU power supply is not turned on, the controller system starts a low-temperature preheating function, the heating sheet is turned on to heat the system to a temperature above a threshold temperature, then the CPU main system is turned on, and the system enters a normal working state. The peripheral circuit components of the controller need to be uniformly selected to be components supporting the operation below 0 ℃. The starting steps of the low-temperature preheating technology of the conventional computer CPU are that the starting action of the key switch is sent out firstly, then the controller starts the preheating circuit, the preheating circuit is delayed to be heated to the specified temperature, and then the CPU power supply is turned on to complete the starting. None of the above pre-heating techniques consider the BMC/CPU two-level management system in common servers. The power-on sequence of the server is that after the server is connected with an external power supply, the server can turn on a standby power supply, the BMC management system is powered on to work first, the server enters a standby mode, and the server can respond to various remote control management commands including remote power-on and the like. And then after the server receives a key or a remote starting instruction, starting a starting power supply to supply power to the CPU main system, and enabling the server to enter a normal working mode. If the server preheating action is also executed after the startup command is received, the server preheating action needs to be completed by the BMC management system. The BMC management system in the server relates to BMC, CPLD and each board card, is difficult to be completely replaced by devices supporting less than 0 degree, cannot ensure that the devices in the BMC management system work at more than 0 degree at any time, and can generate uncontrollable operations such as abnormal starting and data rewriting with extremely low probability when the management system is started below 0 degree, thereby affecting the reliability of the system.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
In view of the above objects, a first aspect of embodiments of the present invention proposes an embodiment of a method for server preheating. Fig. 1 shows a schematic flow diagram of the method.
As shown in fig. 1, the method may include the steps of:
s1, responding to the external power supply of the server, opening the heating sheet arranged at each component on the server to heat each component, integrating each heating chip together to form a preheating circuit, directly opening the preheating circuit when the external power supply is switched on to enable each heating chip to heat the corresponding component, or respectively detecting the temperature of each component to judge whether the component needs to be heated, opening the heating chip which needs to be heated and not needing to be heated;
s2, respectively detecting the real-time temperature of each component and comparing the detected temperature with the threshold temperature of the corresponding component, when the server is started, each component has the lowest working temperature, setting the working temperature as the threshold temperature, monitoring the temperature of the components in real time, and judging whether the temperature of the components reaches the threshold temperature, if the temperature reaches the threshold temperature, the heating can be stopped or continued for a certain time, if the temperature does not reach the threshold temperature, the heating needs to be continued, the real-time temperature of the detection components can be in a temperature sensor mode, and each component can be provided with one or more temperature sensors to ensure the accuracy of the temperature of the detection components;
s3, in response to the fact that the real-time temperature of each component is larger than a threshold temperature, a standby power supply of the server is turned on, when the real-time temperature of each component reaches the threshold temperature, namely, if the server is started up at this time, the server can be turned on without obstacles, the standby power supply of the server can be turned on first to enable the server to be in a standby state, at this time, the server system supports remote access of BMC, the CPU main system is turned on after a starting command is waited for, extra preheating delay is not needed between the time when the starting command is received and the time when the starting power supply is turned on in the standby state, and finally, the BMC management system and the CPU main system cannot work below 0 ℃ at any time, so that the low;
s4 responds to the standby power of the server and receives the instruction of starting the server, and starts the server.
The technical scheme of the invention is that after an external power supply is switched on, if the temperature of a component is lower than a threshold temperature, an independent preheating circuit (the preheating circuit supports the work below 0 ℃) is operated, the temperature of the component is heated to be above the threshold temperature, and then the BMC management system is automatically switched on to enter a standby mode. In the standby state, no additional preheating delay is needed between the time of receiving the starting command and the time of turning on the starting power supply.
By the technical scheme of the invention, absolute safety in the low-temperature starting process can be ensured, and the response speed of the server starting can be increased.
In a preferred embodiment of the present invention, the method further comprises:
setting the maximum heating time of each component according to the threshold temperature of each component;
and closing the heating sheet corresponding to the part in response to the heating time of the part exceeding the maximum heating time corresponding to the part. The preheating of the heating plate during low-temperature starting is further provided with time delay protection, the maximum heating time is limited not to exceed a certain time (for example, 10 minutes, determined according to actual measurement), the heating plate must be closed after the maximum heating time is exceeded, and if the temperature of the component does not exceed the threshold temperature after the heating plate is closed, the heating plate is opened again to heat the component after a certain time is passed until the temperature of the component reaches the threshold temperature. After the standby power supply is turned on, the BMC takes over the control right of the preheating circuit to prevent the overheating problem caused by the abnormity of the preheating circuit
In a preferred embodiment of the present invention, the method further comprises:
setting a pre-heating temperature threshold for each component;
and closing the heating sheet corresponding to the part in response to the real-time temperature of the part being greater than the threshold temperature and reaching the temperature threshold value. Heating the temperature of the component to the threshold temperature only ensures the lowest temperature of the component when the server is started, but not the optimal temperature of the component, different temperature thresholds are set according to the difference of each component, and the heating is stopped when the component reaches the temperature thresholds.
In a preferred embodiment of the present invention, the method further comprises:
in response to the server being powered on, the control device of the server obtains the temperature of each component and controls the heating sheet corresponding to each component to be turned on and off based on the obtained temperature. After the server is started, a control device (such as BMC) of the server is responsible for monitoring the temperature of the component and controlling the heating sheets to be switched on and off according to the optimal temperature of the component to work so as to enable the component to work in the optimal temperature.
In a preferred embodiment of the present invention, the threshold temperature is the minimum temperature required for the components to start up when the server is powered on.
