Description
Technical Field
The present invention relates to the field of server technologies, and in particular, to a method, a system, a medium, and an apparatus for controlling a power supply of a server system.
Background
On a general-purpose X86 architecture computer, there is a function called Restore on AC Power loss, which is generally controlled by the ME in the PCH to realize that the system can automatically restore the state of the computer when the AC (alternating current) power is disconnected and restored. Typically, this function can be set under the BIOS, and if a Last State is selected in the BIOS, it represents what State the system has recovered to based on the State before the Last power down after the AC FAIL has occurred, i.e., after the AC power is disconnected and recovered again.
In the prior art, there are 2 common processing methods:
1. performing AC POWER LOSS related setting in BIOS, storing the related setting into PCH CMOS area, and after POWER-off and restarting, performing information readback from the CMOS area;
2. performing AC POWER LOSS related setting in BIOS, and outputting setting information to CPLD as a state identifier through GPIO; when normal power failure occurs, the computer is usually in a power-off state, and when abnormal power failure occurs, the computer is usually in a power-on state; after the computer power-off is detected, the computer power-off can be determined to be normal power-off or abnormal power-off, so that corresponding computer power-off information is generated, and the information is written into the UFM for storage.
However, the following problems exist in the prior art:
1. storing relevant information in PCH CMOS area will be affected by the precision and life of button cell powered by periphery, when button cell is lowered with voltage at two ends, the reading and storing of data will be at unstable risk;
