Detailed Description
The core of the invention is to provide a power supply monitoring method, a system and a server, when the communication between a monitoring device and a power supply is interrupted, the false alarm of the monitoring device is determined, and a communication link between the monitoring device and the power supply is repaired, so that the false alarm problem caused by the communication interruption between the monitoring device and the power supply is avoided.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a power monitoring method according to an embodiment of the present invention.
The power supply monitoring method comprises the following steps:
step S1: detecting whether a communication link between a power supply and a monitoring device which is directly connected with the power supply and is used for monitoring the working condition of the power supply is interrupted; if not, go to step S2; if yes, go to step S3.
Step S2: and determining that the power failure alarm of the monitoring device is effective.
Step S3: determining that the power failure alarm of the monitoring device is invalid and resetting the power supply and the communication port of the monitoring device and the communication bus therebetween to repair the communication link.
Specifically, referring to fig. 2, fig. 2 is a schematic diagram illustrating a power supply monitoring under an Intel chip topology according to an embodiment of the present invention. In the process of monitoring the power supply, firstly, an Intel chip set ME (Management Engine) passes through I2The C bus reads the information of the power supply, and the monitoring device (such as BMC (Baseboard Management Controller) as the monitoring device) passes through another path I2The C bus reads the information of the power supply from the interior of the ME to ensure that the monitoring device monitors the information of the power supply in real time, and the ME plays a role in bridging in the process. When the server is in the state of S5 (one of the states of the server motherboard, S5 represents that the motherboard AC is powered on but not powered on), the ME is not working properly; after the server enters the state of S0 (one of the states of the server motherboard, S0 represents that the motherboard is already powered on), the ME starts to work normally; when the server enters the S0 state from the S5 state, the motherboard boot signal is sent to the monitoring device and the PCH (integrated south bridge) at the same time, the monitoring device monitors the power information after receiving the signal, and the PCH controls the server to boot after receiving the signal; in the process, when the monitoring device scans the information of the monitoring power supply, the ME does not work normally yet, so that the monitoring device and the ME cannot communicate with each other, the monitoring device records the power supply fault and gives an alarm after detecting that the communication cannot be performed, however, the 'false' alarm is not a real 'fault', and a large amount of work is brought to operation and maintenance personnel.
In order to solve the problems, a direct connection topology design is adopted between the power supply and the monitoring device for monitoring the working condition of the power supply, as shown in fig. 3, namely, the monitoring device is directly communicated with the power supply in any state, and no intermediate link exists, so that the problem of 'error' alarm caused by the intermediate link is effectively solved.
In addition, considering that in the process of communication between the monitoring device and the power supply, the two may be caused by handshake failure and communication interruption due to electromagnetic interference, and at this time, the monitoring device cannot perform monitoring on the power supply, and power failure alarm is performed, so that the problem of false alarm exists, the technical means adopted by the application is as follows:
detecting whether a communication link between a power supply and a monitoring device is interrupted, and if the communication link between the power supply and the monitoring device is not interrupted, indicating that the monitoring device is not a power supply failure alarm caused by the interruption of the communication with the power supply, determining that the power supply failure alarm of the monitoring device is effective; if the communication link between the monitoring device and the power supply is interrupted, the monitoring device is indicated to be a power supply failure alarm caused by the interruption of the communication with the power supply, the power supply failure alarm of the monitoring device is determined to be invalid, namely, the monitoring device is determined to have a false alarm problem due to the interruption of the communication with the power supply, and the communication between the monitoring device and the power supply is repaired.
The communication repair operation between the monitoring device and the power supply specifically comprises the following steps: arranging a first communication fault-tolerant resisting module in the power supply, detecting whether the communication between the power supply and the monitoring device is interrupted or not by the first communication fault-tolerant resisting module, and resetting a communication port of the power supply to recover the communication port of the power supply if the communication is interrupted; if the communication is not interrupted, the reset operation of the power supply communication port is not executed. Similarly, a second communication fault-tolerant resisting module is arranged in the monitoring device, the second communication fault-tolerant resisting module detects whether the monitoring device is interrupted in communication with the power supply, and if the communication is interrupted, the communication port of the monitoring device is reset so as to recover the communication port of the monitoring device; meanwhile, the second communication fault-tolerant resisting module resets a communication bus between the monitoring device and the power supply so as to repair a communication link; if the communication is not interrupted, the reset operation of the communication port and the communication bus of the device is not executed.
More specifically, the first communication fault-tolerant resistant module detects the way of the power supply and the monitoring device communication interruption: recording the time of the monitoring device polling the power supply, if the monitoring device does not access the power supply in 15 polling periods (the monitoring device polls the power supply once a second generally, and 15 polling periods are 15 seconds), determining that the communication between the power supply and the monitoring device is interrupted, and executing the operation of resetting the communication port of the power supply, thereby ensuring that the problem of timely recovery due to the fault of the communication port of the power supply is solved in the process of communication between the power supply and the monitoring device. The second communication fault-tolerant-resisting module detects the mode of the monitoring device and the power supply communication interruption: when the monitoring device does not respond to the power supply communication through periodic detection and recognition, the communication interruption between the monitoring device and the power supply is determined, and the operation of resetting the communication port of the monitoring device is executed, so that the problem of timely recovery due to the fact that the communication port of the monitoring device breaks down in the process of communication between the monitoring device and the power supply is solved. In addition, the second communication fault-tolerant module also performs an operation of resetting the communication port of the monitoring device when a PEC (Parity Check) transmission error is detected during the communication process. The second communication fault-tolerant-resistant module resets the communication bus between the monitoring device and the power supply: the signal (9 clocks) that the monitoring device established communication with the power supply is retransmitted to the power supply.
The invention provides a power supply monitoring method, which detects whether a communication link between a power supply and a monitoring device for monitoring the working condition of the power supply is interrupted; if the power failure alarm is not interrupted, determining that the power failure alarm of the monitoring device is effective; if the power failure alarm is interrupted, the power failure alarm of the monitoring device is determined to be invalid, and the communication ports of the power supply and the monitoring device and the communication bus between the power supply and the monitoring device are reset so as to repair a communication link between the power supply and the monitoring device. Therefore, when the communication between the monitoring device and the power supply is interrupted, the false alarm of the monitoring device is determined, and the communication link between the monitoring device and the power supply is repaired, so that the false alarm problem caused by the interruption of the communication between the monitoring device and the power supply is avoided.
On the basis of the above-described embodiment:
as an optional embodiment, the power supply monitoring method further includes:
pre-establishing address information corresponding relation between the address of a register used for storing power failure information and the stored power failure information;
after the operation parameter information of the power supply is analyzed to obtain the actual fault information of the power supply, a target address corresponding to the actual fault information is determined according to the address information corresponding relation, and a target register corresponding to the target address is written into a preset fault value for the monitoring device to read.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Further, the present application may also establish a correspondence relationship (address information correspondence relationship for short, which may be embodied in a table form) between an address of a register for storing power failure information and the power failure information stored therein in advance, that is, the address information correspondence relationship represents which kind of failure information (such as OVP overvoltage failure, UVP undervoltage failure) of the power supply is specifically stored in each register for storing power failure information. Based on this, after the actual fault information of the power supply is obtained by analyzing the operation parameter information of the power supply, the target address corresponding to the obtained actual fault information, namely the address of the target register for storing the obtained actual fault information, can be determined according to the established address information corresponding relation, and then the preset fault value is written into the target register based on the address of the target register to indicate that the power supply has the fault corresponding to the actual fault information. At the same time, the monitoring device may interact with the power supply to read stored information in a register within the power supply to determine a fault condition of the power supply based on the stored information in the register.
More specifically, referring to fig. 4, fig. 4 is a schematic diagram illustrating a power failure monitoring method according to an embodiment of the present invention. The specific mode of monitoring the power failure by the monitoring device is as follows: the power supply is internally provided with a fault processing module and a register for storing power supply fault information, wherein the fault processing module is used for pre-establishing an address information corresponding relation between the address of the register and the stored power supply fault information, determining a target address corresponding to the actual fault information according to the address information corresponding relation after analyzing the operation parameter information of the power supply to obtain the actual fault information of the power supply, and writing a target register corresponding to the target address into a preset fault value for a monitoring device to read.
As an optional embodiment, the operation parameter information includes input/output parameter information of the power supply and operation parameter information of key components inside the power supply;
and the power supply monitoring method further comprises the following steps:
when the actual fault information of the power supply is analyzed, the fault analysis condition of the power supply is recorded;
the current operation parameter information of the power supply is periodically acquired, and the future fault condition of the power supply is predicted by combining the fault analysis condition of the historical record.
Further, the method analyzes the operation parameter information of the power supply to obtain the actual fault information of the power supply, and specifically analyzes the input and output parameter information of the power supply and the operation parameter information of key components inside the power supply, wherein the input and output parameter information of the power supply is analyzed to obtain the externally dominant fault of the power supply, and the operation parameter information of the key components inside the power supply is analyzed to obtain the faults of the internal structure of the power supply, such as the comprehensive faults and the standard exceeding information of the voltage, the current and the temperature of the key components inside the power supply.
Therefore, when the actual fault information of the power supply is analyzed, the fault analysis condition of the power supply can be recorded and used as the basis for subsequently prejudging the power supply fault. In addition, the method and the device periodically acquire the current operation parameter information of the power supply, and predict the future fault condition of the power supply by combining the fault analysis condition of the historical record.
More specifically, the fault processing module analyzes the operation parameter information of the power supply to obtain actual fault information of the power supply, records a fault analysis log of the power supply, and sends the fault analysis log of the power supply to the monitoring device for saving. The monitoring device periodically polls the current operation parameter information of the power supply from the fault processing module and predicts the future fault condition of the power supply by combining with a fault analysis log stored in history.
As an optional embodiment, the power supply monitoring method further includes:
pre-establishing an index relation corresponding table for searching the power failure type and the failure processing mode according to the power failure information;
after the operation parameter information of the power supply is analyzed to obtain the actual fault information of the power supply, the power supply fault type and the fault processing mode corresponding to the actual fault information are found according to the index relation corresponding table.
Further, the method and the device can also establish an index relation corresponding table used for searching the power failure type and the failure processing mode according to the power failure information in advance, namely the index relation corresponding table represents the power failure type and the failure processing mode corresponding to any power failure information. Based on the method and the device, after the operation parameter information of the power supply is analyzed to obtain the actual fault information of the power supply, the power supply fault type and the fault processing mode corresponding to the obtained actual fault information can be found according to the index relation corresponding table.
More specifically, the fault processing module analyzes the operation parameter information of the power supply to obtain actual fault information of the power supply, and sends the actual fault information to the monitoring device (such as the BMC). The BMC stores the index relation corresponding table in advance, and after receiving the actual fault information, searches the power failure type and the fault processing mode corresponding to the obtained actual fault information according to the index relation corresponding table. For operation and maintenance personnel, the fault type and how to process the current fault can be known by remotely accessing the BMC WEB interface, so that the maintenance cost is saved.
As an optional embodiment, the power supply monitoring method further includes:
and when the searched fault processing mode is the firmware upgrading mode, triggering a chip for upgrading the firmware in the power supply to carry out online firmware upgrading.
Further, if the fault processing mode corresponding to the current fault information of the power supply is a firmware upgrading mode, the current fault of the power supply is eliminated by upgrading the firmware of the power supply. The existing system upgrading mode is as follows: the offline power supply upgrade is to take the power supply out of the system, and use a tool composed of a jig board, a computer, a burner, a USB (Universal Serial Bus) cable, a USB conversion head, and a PMBus (power management Bus) cable to upgrade the firmware of the power supply one by one. The method adopts online upgrading, and particularly, the monitoring device sends an upgrading instruction to the power supply to trigger a chip for upgrading firmware in the power supply to upgrade the firmware online, so that the method is simple and convenient.
As an alternative embodiment, the chip comprises a first chip core and a second chip core;
correspondingly, the process of triggering a chip for firmware upgrade in a power supply to perform online firmware upgrade comprises the following steps:
detecting whether a first chip core pre-designated to execute firmware upgrading operation fails;
if not, triggering the first chip core to execute firmware upgrading operation;
if yes, triggering the second chip core to execute the firmware upgrading operation.
Specifically, the chip for firmware upgrade adopts a dual-core chip, namely two chip cores are guaranteed to be mirror images of each other, if one chip core fails, the other chip core can continue to execute firmware upgrade operation, so that the successful online effective upgrade of the power firmware can be ensured, and meanwhile, the situation that the system fails to upgrade due to abnormity (such as interruption, interference, code error, sudden power failure in the upgrade process and the like) in the firmware upgrade process and further the system is crashed can be prevented.
