Description

Method, apparatus, equipment and the storage medium of server system power management
Technical field
The present invention relates to server system technical field, more particularly to a kind of server system power management method, Device, equipment and computer readable storage medium.
Background technique
Overcurrent protection (OCP) or fan lock (FAN LOCK) etc. are occurring for the power supply (PSU) applied in server system Out-put supply can be cut off when situation.Only it could restore normal electricity after the problems such as OCP problem or fan failure solves Source supply.But partial power because of reliability the problem of or FW update the problems such as, power failure releasing after need server The system management module of system is to ability normal Activate power supply after failure PSU wake-up command.But it is when power failure System management module only could restore the normal of power supply by carrying out artificial plug to power supply at this time because power-off also can not work normally For electricity output, the adjustable of machine system is affected.
In summary as can be seen that how not influence the adjustable of server system when power failure releases In the case of to restore power supply for electricity output be current problem to be solved.
Summary of the invention
The object of the present invention is to provide method, apparatus, equipment and the computers of a kind of server system power management can Storage medium is read, plug just can be extensive in order to solve to need after power failure releasing in the prior art to carry out manually power supply The output of telegram in reply source normal power supply, reduces the adjustable of server system.
In order to solve the above technical problems, the present invention provides a kind of method of server system power management, comprising: judgement clothes Whether the power supply for device system of being engaged in spontaneous can restore electricity output after power failure releasing;If the power supply of the server system exists After power failure releases, spontaneous can not restore electricity output, then utilize the spare output of the power module of the server system It powers to the system management module of the server system, to make the system management module to the electricity of the server system Source send wake-up command, activate the power supply of the server system for electricity output.
Preferably, if the power supply of the server system spontaneous can not restore electricity defeated after power failure releasing Out, then it is powered using the spare output of the power module of the server system to the system management module of the server system Include:
If the power supply of the server system after trouble shooting, spontaneous can not restore electricity when exporting, then using switch Module opens the spare power path being output between the system management module of the power module, closes the server system The power supply of system, so that the spare output using the power module powers to the system management module.
Preferably, include: after the spare output using the power module powers to the system management module
Judge that the system management module is to restore electricity, if not restoring electricity, control instructions module is to staff Prediction occurring signal;
If being successfully recovered, called out using the system management module after restoring electricity to the transmission of the power supply of the server system It wakes up and instructs, in order to activate the power supply of the server system, make the power up of the server system for electricity output.
Preferably, whether spontaneous recovery power supply power supply is defeated after power failure releasing for the power supply for judging server system After out further include:
If the power supply of the server system spontaneous recovery of energy, electricity of the server system after power failure releasing Source closes the spare of the power module by the switch module and is output to the system administration mould after power failure releasing The power path of block, so that the power supply using the server system is powered the system management module.
Preferably, whether the power supply for judging server system spontaneous can restore electricity output after power failure releasing Before further include:
The fault type of the power supply of detection service device system, and the fault type is sent to the staff, with It is overhauled convenient for the staff according to power supply of the fault type to the server system;
After the staff completes the maintenance to the power supply of the server system, the server system is judged Whether power failure releases;
Whether if releasing, executing the power supply for judging server system can spontaneous recovery confession after power failure releasing The operation of electricity output.
The present invention also provides a kind of devices of server system power management, comprising:
Judgment module, for judging it is defeated whether the power supply of server system spontaneous can restore electricity after power failure releasing Out;
Wake-up module, if the power supply for the server system spontaneous can not restore electricity after power failure releasing Output is then supplied using the spare output of the power module of the server system to the system management module of the server system Electricity activates the server system so that the system management module be made to send wake-up command to the power supply of the server system The power supply of system for electricity output.
Preferably, the wake-up module is specifically used for:
If the power supply of the server system after trouble shooting, spontaneous can not restore electricity when exporting, then using switch Module opens the spare power path being output between the system management module of the power module, closes the server system The power supply of system, so that the spare output using the power module powers to the system management module.
Preferably, after the judgment module further include:
Spontaneous recovery module, if the spontaneous recovery of energy after power failure releasing of the power supply for the server system, The power supply of the server system closes the spare defeated of the power module by the switch module after power failure releasing The power path of the system management module is arrived out, thus using the power supply of the server system to the system management module It is powered.
The present invention also provides a kind of equipment of server system power management, comprising:
Memory, for storing computer program;Processor realizes above-mentioned one kind when for executing the computer program The step of method of server system power management.
The present invention also provides a kind of computer readable storage medium, meter is stored on the computer readable storage medium Calculation machine program, the computer program realize a kind of step of the method for above-mentioned server system power management when being executed by processor Suddenly.
The method of the server system power management of server system power management provided by the present invention, first determines whether to take The power supply type for device system of being engaged in, judges that the power supply of the server system is the output that spontaneous can restore electricity after trouble shooting Power supply, the power supply for the output that still spontaneous cannot restore electricity.If the power supply of the server system power failure releasing after, Cannot the output of spontaneous recovery power supply normal power supply, using the server system power module spare output to the service The system management module of device system is powered.It, can be to the server system after the system management module restores electricity Power supply sends wake up instruction, activates the power supply of the server system, makes the power up normal power supply of the server system Output.Method provided by the present invention utilizes institute in the case where the power supply of the server system sends failure and cuts off the power The spare output for stating the power module of server system is that the system management module is powered, and utilizes the system administration Module to the power supply of the server system send wake-up command, activate the power supply of the server system for electricity output, no It needs manually to plug the power supply of the server system, improves the adjustable of the server system.
Corresponding, device provided by the present invention, equipment and computer readable storage medium all have above-mentioned beneficial Effect.
