Description

Server fan state monitoring method and system

The invention relates to a server device monitoring method and system, in particular to a server fan state monitoring method and system.

As servers become more and more used in a variety of industries, server configurations are becoming more sophisticated. However, some potential problems in the development of the server are often neglected. For example, the loss of the fan, the server works in a high-intensity environment for a long time, the situation of the machine cannot be found in the middle, and the loss of the fan is slow. Slow highlights. Although the baseboard management controller in the existing server provides the function of detecting the fan speed, it cannot detect physical changes such as the fan shaft. For example, the shaft inside the fan affects the normality of the fan due to external factors such as dust. Running.

In view of the above, it is necessary to provide a server fan state monitoring method and system.

The server fan state monitoring method includes: searching for a noise sensor mounted on the system management bus; reading step, reading the noise generated by the noise sensor obtained by the noise sensor Decibel value; comparison step, comparing the read noise decibel value with a preset value, the preset value is the maximum noise value allowed when the tested fan works normally, when the read noise decibel value is not greater than the preset When the value is ended, the process ends; the triggering step, when the read noise decibel value is greater than the preset value, the alarm light that triggers the baseboard management controller lights up.

The server fan state monitoring system includes: a search module for finding a noise sensor mounted on the system management bus; and a reading module for reading the fan work obtained by the noise sensor The decibel value of the noise formed at the time; the comparison module is configured to compare the read noise decibel value with a preset value, and the preset value is the maximum noise value allowed when the tested fan works normally; the trigger module When the noise decibel value read is greater than the preset value, the alarm light that triggers the baseboard management controller is illuminated.

The invention provides a server fan state monitoring method for judging the current state of the fan through the noise emitted by the fan, so as to be processed early to avoid unpredictable unexpected situations.

FIG. 1 is a schematic diagram showing an operating environment of a preferred embodiment of the server fan state monitoring system of the present invention. The server fan state monitoring system 10 is applied to the server 1. The server 1 includes a baseboard management controller (BMC), a fan 14, a system management bus 16, and a noise sensor 18.

The baseboard management controller 12 is a dedicated chip that supports the industry standard IPMI specification, which describes management functions already built into the motherboard, such as local and remote diagnostics, console support, configuration management, hardware management, and faults. exclude.

The baseboard management controller 12 further includes a memory 120, a processor 121, an alarm light 122, and an alarm 123.

The memory 120 is used to store information such as information of the noise sensor 18 (for example, information such as the address of the noise sensor 18) and the code of the server fan state monitoring system 10.

The alarm light 122 is used to light an alarm when the noise decibel value of the fan 14 acquired by the noise sensor 18 is greater than a preset value; the alarm 123 is used for reading by the noise sensor 18 When the noise decibel value of the fan 14 is greater than a preset value, an alarm sound is generated, and the preset value is the maximum noise value that can be allowed when the tested fan works normally.

The fan 14 discharges hot air inside the server 1 to cool components such as a computer case, a processor, a graphics card chip, and a hard disk inside the computer, which generate high heat due to high power consumption, to prevent the components from overheating, malfunctioning, or damage.

The noise sensor 18 is configured to obtain a decibel value of the noise generated when the fan 14 is in operation. The noise sensor 18 is mounted on the system management busbar 16 and is connected to the fan 14 through the system management busbar 16.

In this embodiment, the server fan state monitoring system 10 can be divided into one or more modules, and the one or more modules are stored in the memory 120 of the substrate management controller 12 and It is configured to be executed by one or more processors (one processor 121 in this embodiment) to complete the present invention. For example, referring to FIG. 2, the server fan state monitoring system 10 is divided into a search module 100, a read module 102, a comparison module 104, and a trigger module 106. The module referred to in the present invention is a program segment for performing a specific function, and is more suitable for describing the execution process of the software in the substrate management controller 12 than the program. For the function of each module, refer to the description of FIG.

3 is a flow chart of a preferred embodiment of the server fan status monitoring method of the present invention.

In step S20, the search module 100 traverses the system management bus 16 to find a system management bus with a certain ID number for mounting the noise sensor 18, and the ID number is each of the systems management bus 16 included. The number of the bus.

In step S21, the search module 100 searches for the noise sensor 18 on the system management bus with the certain ID number of the mounted noise sensor 18, where the noise sensor 18 can be managed according to the system. The offset address on the bus bar is used to find the noise sensor 18, and the offset address is the offset of the noise sensor 18 on the system management bus bar relative to the system management bus start address. The address is recorded in the memory 120 of the baseboard management controller 12 and is read by the seek module 100.

In step S22, the reading module 102 reads the decibel value of the noise formed when the fan 14 obtained by the noise sensor 18 operates. After the noise sensor 18 obtains the noise decibel value formed when the fan 14 is working, the noise decibel value is stored in a register with a certain offset address in the noise sensor 18, The offset address of the register is an offset address relative to the start address of the noise sensor 18, and the offset address is recorded in the memory 120 of the substrate management controller 12, and the read module 102 reads the offset address and reads a noise decibel value stored in a temporary register having the offset address.

In step S23, the comparison module 104 compares the read noise decibel value with a preset value, and the preset value is the maximum noise value that can be allowed when the tested fan 14 is working normally, when the noise is read. When the value is not greater than the preset value, the process ends.

In step S24, when the read noise decibel value is greater than the preset value, the fan 14 has a potential risk (for example, the rotating shaft inside the fan affects the normal operation of the fan 14 due to interference of other external factors such as dust), and the trigger module 106 The trigger warning light 122 illuminates and triggers the alarm 123 to emit an abnormal alarm sound to prompt the operator to handle the potential risk in time.

The steps S20 to S24 are used to determine the current state of the fan through the noise emitted by the fan 14 to facilitate early processing to avoid unpredictable unexpected situations.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
