The chassis lock control instruction may be an IPMI (Intelligent Platform Management Interface, intelligent platform management interface) instruction issued by an upper-layer application, and is used to control the server chassis lock.

The chassis lock control command mentioned in this step may be an unlock command or a lock command. When the chassis lock control command is an unlock command, the target state of the server chassis lock is an unlock state, and when the chassis lock control command is an unlock command When it is the lock command, the target state of the server chassis lock is the lock state. The target state refers to the state that requires the server chassis lock to reach.

S102: Set the level state of the target GPIO pin on the server motherboard according to the target state, so as to control the server chassis lock to be unlocked or locked;

In this embodiment, the corresponding relationship between the target state and the level state of the target GPIO pin may be pre-stored, and after the target state is determined, the level state of the target GPIO pin may be set according to the corresponding relationship.

As a feasible implementation manner, if the number of target GPIO pins is 1, when the target state is the unlocked state, the target GPIO pin can be set to a low level; when the target state is the locked state, the target GPIO pin can be set to a low level; Set the target GPIO pin high. If the number of target GPIO pins is greater than 1, when the target state is an unlocked state, all target GPIO pins can be set to a low level; when the target state is an unlocked state, any number of target GPIO pins can be set to GPIO pins are set high. Through the processing method that the number of target GPIO pins is greater than 1, the server chassis lock can be in an unlocked state only when all GPIO pins are set to a high level, which improves the security protection performance of the server chassis.

The server chassis lock mentioned in this embodiment is a lock structure set on the server chassis. When the server chassis lock is in an unlocked state, the server chassis can be opened, and when the server chassis lock is in a locked state, the server chassis cannot be opened. . In this embodiment, the server chassis lock can be connected to the target GPIO pin. When the level state of the target GPIO pin is the first level state, the server chassis lock is in the unlocked state, and when the target GPIO pin is in the unlocked state When the level state of the pin is the second level state, the server chassis lock is in a locked state.

As a feasible implementation manner, in this embodiment, when the level state of the target GPIO pin is the first level state, a corresponding prompt sound can be played to inform the user that the server chassis can be opened, so that the staff can open the server Chassis replaces internal components. Correspondingly, when the level state of the target GPIO pin is the second level state, a corresponding prompt sound is played to inform the user that the server chassis may be locked.

In this embodiment, the input attribute of the GPIO pin is changed to the output attribute, the target state that needs to be achieved by the server chassis lock is determined according to the received chassis lock control instruction, and the level state of the GPIO pin is set according to the target state. In this embodiment, the lock/unlock state of the server chassis lock is changed according to the level state of the GPIO pin. Therefore, the server chassis can be unlocked and unlocked by setting the GPIO pin level according to the chassis lock control command, which can prevent the chassis from being locked and unlocked. trespass.

Wherein, when the level state of the target GPIO pin is the first level state, the server chassis lock is in an unlocked state, and when the level state of the target GPIO pin is the second level state The server chassis lock is in the locked state.

S203: When the server chassis is in a powered-on state, set the level state of the target GPIO pin to the second level state.

Among them, when the server chassis is powered on, it means the server is in working state. Opening the server chassis at this time will affect the normal operation of the server. Therefore, when the server chassis is powered on, the level state of the target GPIO pin can be set to the above A second level state to set the server chassis lock to the locked state.

S204: Update the server chassis switch record according to a preset cycle;

Set a GPIO pin on the server motherboard to control the unlocking and unlocking of the chassis through the level of high and low. The BMC on the motherboard is responsible for accepting the IPMI command, and the BMC controls the level of the root GPIO pin according to the content of the IPMI command. This GPIO pin is high by default, and is locked when high. When the server is powered on, the GPIO pin is at a high level by default, so the chassis will be locked automatically. You need to make the BMC change this GPIO pin to a low level through the IPMI command to unlock, and the chassis can be opened after unlocking.

Referring to FIG. 4 , FIG. 4 is a working principle diagram of a finite state machine provided by an embodiment of the present application. The chassis is unlocked when it is not powered on, which is convenient for operators to replace internal components. When the chassis is powered on, the hardware design of the motherboard will lock the chassis lock immediately.
