Description

Method, system and storage medium for monitoring server power supply abnormality
Technical Field
The invention relates to the technical field of computers, in particular to a server power supply abnormality monitoring method, a system and a storage medium.
Background
In the big data age, the data center bears massive operational data, the deployed servers are more and more dense, and the requirements on the stability and the reliability of the servers are continuously improved. As the service time increases, the factors that cause the server to malfunction are increasing, because the server needs 24 hours to operate continuously. When a server deployed in the data center has abnormal power failure, the current power state needs to be recorded for subsequent analysis by engineers, so that the failure cause is rapidly positioned. Therefore, developing a fast, accurate and stable fault recording mechanism is a technical problem to be solved urgently by those skilled in the art.
As shown in fig. 1, the fault detection and recording mechanism adopted in the prior art is implemented based on CPLD (complex programmable logic device) and BMC (baseboard management controller) in a collocation manner. The key power supply signal of the server is connected to the CPLD through hardware, and the CPLD is sequentially pulled up or pulled down according to a power-on time sequence designed in advance when the server is started, so that the power-on process of the server is completed. During the startup and operation of the server, the CPLD continuously monitors the status of the incoming power signals, including signals such as EN, PWRGD, alert of devices such as a CPU (central processing unit), PSU (power supply), DIMM (dual in-line memory module), and intelligent network card (OCP). As shown in fig. 1, and report the real-time status to the BMC over the i2c bus. When an abnormality occurs, a technician can locate the fault reason according to the log recorded by the BMC. However, in the above-described monitoring process, there are the following problems:
(1) If an abnormality occurs in the power-on starting process, for example, if the power-on of a certain key signal power supply signal is overtime or the power is abnormally turned off, the CPLD can detect the abnormality, but the BMC may not be started successfully at this time or still be in the starting process, the abnormality state reported by the CPLD cannot be received, so that the cause of the abnormality cannot be recorded. If the fault is probability occurrence, the cause of the follow-up positioning fault is very difficult;
(2) In the running process of the server, after part of electrical signals are abnormal, BMC is hung up, so that abnormality cannot be recorded;
(3) Some clients may require shutdown to protect the device immediately after the abnormal power failure occurs, which causes that after the abnormal power failure occurs, the BMC does not acquire the power signal states from the CPLD yet, and the server shuts down, so that the BMC cannot record the abnormal power failure.

In the big data age, the data center bears massive operational data, the deployed servers are more and more dense, and the requirements on the stability and the reliability of the servers are continuously improved. As the service time increases, the factors that cause the server to malfunction are increasing, because the server needs 24 hours to operate continuously. When a server deployed in the data center has abnormal power failure, the current power state needs to be recorded for subsequent analysis by engineers, so that the failure cause is rapidly positioned. Therefore, developing a fast, accurate and stable fault recording mechanism is a technical problem to be solved urgently by those skilled in the art. In the existing monitoring process, the following problems exist: if an abnormality occurs in the power-on starting process, for example, if the power-on of a certain key signal power supply signal is overtime or the power is abnormally turned off, the CPLD can detect the abnormality, but the BMC may not be started successfully at this time or still be in the starting process, the abnormality state reported by the CPLD cannot be received, so that the cause of the abnormality cannot be recorded. If the fault is probability occurrence, the cause of the follow-up positioning fault is very difficult; in the running process of the server, after part of electrical signals are abnormal, BMC is hung up, so that abnormality cannot be recorded; some clients may require shutdown to protect the device immediately after the abnormal power failure occurs, which causes that after the abnormal power failure occurs, the BMC does not acquire the power signal states from the CPLD yet, and the server shuts down, so that the BMC cannot record the abnormal power failure.

The first flash memory module comprises, but is not limited to, a UFM module, the first flash memory module is arranged in the CPLD, the server is powered off and restarted, after the server is powered off and restarted and the BMC is started, the BMC reads power-on abnormal information from the UFM module, and analyzes and locates the fault reason.
If the power-on state is not abnormal, the power-on state data are stored in the second storage module, after the BMC is started, the BMC reads the server state data in the second storage module through the i2C bus and checks whether the power-on process is abnormal or not so as to judge the state of the server power supply. Wherein the second memory module includes, but is not limited to, a FIFO module, the FIFO being disposed in the CPLD.
After the power-on process is successfully completed, the server starts to operate, and when an abnormality occurs in the operation process, the following steps are started.

If the abnormal signal can cause the BMC to hang up, the abnormal power failure information is recorded in the third storage module and the second flash memory module at the same time so as to read and locate the fault reason after the BMC is started. Specifically, the CPLD records the abnormal power-down information in the UFM, performs power-down restarting on the server, reads the abnormal power-down information from the UFM after the server is powered down and restarted and after the BMC is started, and analyzes and locates the cause of the fault.
If abnormal power-off information does not occur in the running process of the server, the data after the server is started are stored in the second storage module, after the BMC is started, the data after the server is started are read from the second storage module, and whether the server is abnormal or not is checked.
Through the arrangement, the first storage module, the second storage module, the third storage module, the first flash memory module and the second flash memory module in the CPLD are utilized to temporarily store abnormal states in the power-on state and the running state, so that a technician can quickly locate the fault cause by utilizing the information after recovering the BMC, the time required for the problem reproduction is reduced, and the efficiency of locating the fault cause is improved.
