and S3, corresponding to preset coping strategies based on the risk levels, wherein the coping strategies comprise field inspection, and early warning prompt of a server power supply is carried out by combining a field inspection result and the risk levels, and the field inspection is used for obtaining external environment information of the server.
In one implementation manner of the embodiment of the present invention, the method further includes the steps of:
and for the server power supply which sends the early warning prompt, a fault point is positioned and maintained through the troubleshooting robot.
In step S1, the state information includes temperature information of the power supply, an overcurrent signal output by the power supply, and an overvoltage signal.
The monitoring of the state information specifically comprises: the server BMC polls the power state information of the server and compares the power state information with the specification value, if the power state information does not meet the requirement of the specification value, the BMC displays the power alarm state, reads the parameter information of the alarm power supply of the server through the CPLD based on the power alarm state, and compares the parameter information with the alarm information fed back by the BMC. If the comparison results are different, the instruction is issued to command the BMC to read again and feed back until the comparison results are the same. And if the fault alarm information is matched with the fault alarm information fed back by the BMC, determining the fault alarm information to be abnormal information.
The CPLD real-time polling server power supply register is characterized in that characteristic parameter (real-time voltage values and working states of a PFC feedback circuit, a PFC OVP detection loop and the like, working temperatures and states of a key circuit diode, a communication optical coupler, an isolation drive IC, a standby control chip and a standby integrated chip) index data of each power supply component are collected by a power supply sensor in real time, the CPLD records parameter data of each key component of the power supply, analyzes the key parameter data of each power supply component and compares the key parameter data with a specification interval. If the polling data is within the range of the standard specification interval, the power state output is 00; if the polling data exceeds the range of the standard specification interval, the power state output of each power supply abnormal component is 01; if the polling data of the same component or the same characteristic parameter continuously exceeds the range of the standard specification interval for 3 times, the power state output of each power supply abnormal component is 10.
The CPLD monitors index data such as output power consumption, output current, voltage (12V, vingiod, alert and PG) of a server power supply in real time, the index data are obtained through a power supply register, and a power supply chip obtains and/or calculates the index data in real time and stores the index data in the power supply register; and the CPLD polls and records the data of each parameter and compares the data with the specification value. In order to ensure the power supply redundancy of the whole machine, the output power consumption of the power supply of the machine room server is less than 50 percent (within the standard specification range) of the rated power of the power supply; in order to ensure the stable power supply of the whole machine, the output current of 2 power supplies of the power supply of the machine room server meets the current sharing requirement (the standard specification range is less than 20% of load, the current sharing degree is less than 10%, and the current sharing degree is less than 5% of the load of 20% or more); in order to ensure the power supply and communication reliability of the server power supply, the output signal quality of 12V (standard specification range: 12.0V-12.8V), vingiod (standard specification range: 2.4V-3.46V), alert (standard specification range: 2.4V-3.46V) and PG (standard specification range: 2.4V-3.46V) of the server power supply is within the specification range. If the polling data is within the range of the standard specification interval, the power state output is 00; if the polling data exceeds the range of the standard specification interval, the output of each abnormal state of each power supply is 01; if the polling data exceeds the range of the standard specification interval for 3 times continuously, the power state output is 10. The server power supply state online monitoring module collects the power supply alarm information and the power supply state output value, and transmits the collected information to the server power supply reliability early warning module.
In step S2, alarm information and power state output values of each power supply of the server transmitted by the server power state online monitoring module are received and summarized, a power reliability state general table of the server in the machine room is generated, and the server power supplies are divided into a low risk area (power state output value 00), a medium risk area (power state output value less than 10), and a high risk area (power state output value greater than or equal to 10) based on the power reliability state general table information.
For the low-risk area power supply, generating a low-risk power supply list; and for the power supply in the middle risk area, generating a risk power supply list and corresponding alarm information to a data center machine room control module to perform power supply reliability identification analysis. For the power supply in the high risk area, the server power supply reliability early warning module transmits a high risk power supply list and corresponding warning information to the data center machine room control module to perform power supply overhaul flow analysis.
In step S3, for the medium-risk server power supply, the machine room manager needs to determine whether the risk warning information of each power supply is an effective warning that needs to be managed and controlled, and finally, evaluate the early warning level of the server power supply. If the final early warning level of the server power supply is in danger and the site inspection needs exist, the accurate position of a fault server part is located, a server power supply index acquisition command is issued to the automatic machine room maintenance robot through the internet of things wireless transmission technology, the automatic machine room maintenance robot moves to the fault server position according to fault location to shoot, acquire indexes such as video and smell of the fault power supply working state, transmit acquired data to a data center machine room control module, and machine room management personnel check and process feedback information through a visual interface of the control module.
For the high-risk server power supply, the machine room manager judges whether the risk alarm information of each power supply is an effective alarm needing to be controlled, and finally evaluates the early warning level of the server power supply. If the final early warning level of the server power supply is high risk and the need of field power supply replacement exists, a machine room manager issues a power supply replacement field confirmation instruction to the automatic server power supply maintenance module, the automatic server power supply maintenance module receives the need and positions the accurate position of a fault server part, a server power supply index acquisition command is issued to the automatic machine room maintenance robot, the automatic machine room maintenance robot moves to the position of the fault server according to fault positioning to shoot, acquire indexes such as video and smell of the fault power supply working state, and transmits acquired data to the data center machine room control module.
