Description

A power control method, system, medium and device for a server system

technical field

The present invention relates to the technical field of servers, in particular to a power control method, system, medium and equipment of a server system.

Background technique

On general-purpose X86-based computers, there is a function called Restore on AC Power loss, which is generally controlled by ME in the PCH, so that the system can automatically restore the state of the computer when the AC (alternating current) power supply is disconnected and restored. Usually this function can be set under the BIOS. If you select Last State in the BIOS, it means that after AC FAIL occurs, that is, after the AC power supply is disconnected and restored again, the system judges which state to restore to according to the state before the last power failure.

In the existing technical solutions, there are two commonly used processing methods:

1. Perform AC POWER LOSS related settings in the BIOS, and then the related settings are stored in the PCH CMOS area, and the information is read back from the CMOS area after power off and on again;

2. Perform AC POWER LOSS related settings in the BIOS, and output the setting information to the CPLD through GPIO as a status indicator; when a normal power failure occurs, the computer is usually in the shutdown state, and when an abnormal power failure occurs, the computer is usually in the power-on state; after the computer power failure is detected, it can be determined whether the computer power failure is normal or abnormal power failure, thereby generating the corresponding computer power failure information, and writing this information to UFM for storage.

But there is following problem in existing technical scheme:

1. Storing relevant information in the PCH CMOS area will be affected by the accuracy and lifespan of the button battery powered by the periphery. When the voltage at both ends of the button battery drops with use, the reading and storage of data will face the risk of instability;

2. After the computer is powered off, the CPLD still needs to work for a certain period of time (for example, more than 5 seconds) to write the status identifier into the CPLD. For example, when writing to the UFM of the CPLD, a supercapacitor needs to be added for power supply; and the use of UFM will consume a lot of CPLD logic resources, and the requirements for the selection of the CPLD are high, which increases the system cost to a certain extent; and it is not rigorous enough to use a common cognition to deal with the state of the system when the power is turned off.

It automatically restores to the previous state, achieving the effect of streamlining the system architecture; at the same time, it can save the high material cost caused by the use of high-specification CPLD; through the state information storage that does not depend on the button battery, the power control of the server system is more stable and reliable, ensuring the stability of data storage.

In some embodiments, identifying the on/off state of the server system based on the judgment result includes: identifying that the server system is in the power-on state in response to the level state of the power state signal being the first preset level state; and identifying that the server system is in the power-off state in response to the level state of the power state signal being the second preset level state.

In some embodiments, using the system management module to control the power-on or power-off of the server system based on the identification result includes: in response to identifying that the server system is in the power-on state, the system management module sends a power-on signal to the logic control module to make it control the server system to power on so as to continue to maintain the power-on state; in response to recognizing that the server system is in the power-off state, the system management module keeps the server system in the power-off state by not sending a power-on signal.

When the level state of the power state signal is a low level state, it is recognized that the server system is in the shutdown state, and the system management module does not send a power-on signal to the logic control module, so that the server system remains in the shutdown state before power-off.

In some embodiments, the method further includes: in response to the normal AC power supply during operation of the server system, sending power supply signals to the logic processing module and the system management module respectively through the system power supply module.

In the above embodiment, the other two types of the AC power loss recovery policy (AC POWER LOSS POLICY) are Always on and Always off respectively. Always on means that after AC FAIL occurs, that is, after the AC power supply is disconnected and restored again, the system will automatically turn on regardless of the state before the last power failure. Always off means that after AC FAIL occurs, that is, after the AC power supply is disconnected and restored again, the system will not start regardless of the state before the last power failure.
