Detailed Description
The core of the application is to provide a fan wind direction control method, the fan wind direction control method can be used for quickly and efficiently controlling the wind direction of a server fan, and the waste of labor cost and time cost is effectively reduced; another core of the present application is to provide a fan wind direction control apparatus, an electronic device, and a computer-readable storage medium, all having the above-mentioned advantages.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.
The embodiment of the application provides a method for controlling the wind direction of a fan.
Referring to fig. 1, fig. 1 is a schematic flow chart of a fan direction control method provided in the present application, where the fan direction control method is applied to a baseboard management controller and may include the following steps S101 to S104.
S101: when a fan control command is received, determining a target wind direction according to the fan control command;
this step is intended to enable the reception of fan control commands and the determination of the target wind direction. The fan control command is a command for controlling the wind direction of the server fan, and the obtaining manner does not affect the implementation of the technical scheme, for example, the fan control command may be directly input from the front end by a user according to the current demand, or may automatically respond according to a preset trigger condition, which is not limited in this application. In addition, the target wind direction is the fan wind direction required by the server in the current running state, and comprises a forward direction and a reverse direction.
In the implementation process, when a fan control command is received, the target wind direction may be determined according to the fan control command, and it may be understood that, because the obtaining manner of the fan control command is not unique, the implementation manners of determining the target wind direction according to the fan control command may also be different, which is not limited in this application.
Further, after the target wind direction of the server fan is obtained, the target wind direction may be temporarily stored in the preset storage space, so as to be directly called for use in the subsequent wind direction comparison process (S103). Similarly, the specific type of the preset storage space does not affect the implementation of the present technical solution, for example, the target wind direction may be temporarily stored in an eeprogram (Electrically Erasable Programmable read only memory) of the baseboard management controller.
S102: reading a current wind direction from a preset storage address;
the step aims to realize the acquisition of the current wind direction, wherein the current wind direction is the current wind direction provided by the server fan, namely the running wind direction before the fan wind direction control is not carried out. Specifically, the current wind direction of the server fan is pre-stored in a preset storage address, so that after a fan control command is received, the current wind direction can be directly read from the preset storage address.
The preset storage address may specifically be a certain register address of the fan control chip, such as the register address 0x32, and in the implementation process, the information about the current wind direction fed back by the preset storage address may be obtained by directly sending a data reading command to the register address 0x 32.
Furthermore, after the current wind direction of the server fan is obtained, the current wind direction of the server fan may be temporarily stored in a preset storage space, so as to be directly called and used in the subsequent wind direction comparison process (S103). Similarly, the specific type of the preset storage space does not affect the implementation of the present technical solution, for example, the current wind direction may be temporarily stored in the virtual memory of the baseboard management controller. Of course, the temporary storage positions of the target wind direction and the current wind direction can be the same or different, and the temporary storage positions are not limited in the application.
S103: judging whether the target wind direction is consistent with the current wind direction; if not, executing S104;
this step aims to achieve a wind direction comparison to determine whether the target wind direction of the server fan is consistent with the current wind direction. It can be understood that when the two are consistent, the current wind direction is indicated to meet the current actual requirement, and the wind direction adjustment of the server fan is not needed.
The wind direction of the fan can be represented by a preset flag bit, when the flag bit is 1, the wind direction of the fan is represented as a forward direction, and when the flag bit is 0, the wind direction of the fan is represented as a reverse direction, so that whether the target wind direction is consistent with the current wind direction or not is judged, that is, whether the flag bits of the target wind direction and the current wind direction are consistent or not is judged.
S104: and issuing a reverse control command to the fan driver so that the fan driver controls the fan to rotate reversely.
This step is intended to achieve reverse control of the server fans. It can be understood that the rotation of the fan is realized by the fan driver, and therefore, in order to realize the control of the wind direction of the fan, a control instruction needs to be issued to the fan driver. On the basis, when it is determined that the target wind direction of the server fan is inconsistent with the current wind direction, it may be determined that a current wind direction adjustment needs to be performed, that is, the wind direction of the server fan needs to be adjusted to a wind direction opposite to the current wind direction, at this time, a reverse control instruction may be issued to the fan driver, where the reverse control instruction is used to control the fan driver to perform reverse rotation, and therefore, after obtaining the reverse control instruction, the fan driver may respond to the reverse control instruction to perform reverse rotation, so as to drive the server fan to perform reverse rotation, so as to provide a wind direction opposite to the current wind direction. Thus, the wind direction control of the server fan is realized.
Obviously, according to the fan wind direction control method provided by the embodiment of the application, the wind direction control of the fan in the server is realized through the substrate management controller, the target wind direction required in the current state can be determined according to the received fan control command, and whether the fan needs to be reversely controlled or not is determined by comparing the target wind direction with the current wind direction of the fan, so that the wind direction control of the server fan is realized.
In an embodiment of the application, the determining the target wind direction according to the fan control command may include:
judging the type of the fan control command;
if the fan control command is an automatic control command, acquiring equipment configuration information according to the automatic control command, and determining a target wind direction according to the equipment configuration information;
and if the fan control command is a manual control command, performing field analysis on the manual control command to obtain the target wind direction.
As described above, the obtaining manner of the fan control command is not unique, and further, the implementation manners of determining the target wind direction according to the fan control command may be different, and embodiments of the present application provide two different types of obtaining methods of the fan control command and corresponding implementation methods of determining the target wind direction according to the fan control command.
Specifically, the fan control command may be divided into two types, one is an automatic control command and the other is a manual control command, where the automatic control command is used to determine a target wind direction of the fan according to the actual situation of the server, and the manual control command is used to directly specify the target wind direction of the fan by the user, so that before the target wind direction is determined according to the fan control command, the type of the fan control command may be determined, and then a corresponding operation may be performed according to the command type to determine the target wind direction of the server fan.
In the implementation process, after a fan control command is received, firstly judging the command type, further, if the command is an automatic control command, responding to the automatic control command to acquire equipment configuration information of a server, and then determining a target wind direction according to the equipment configuration information; in the case of a manual control command, since the target wind direction is directly specified by the user, the field analysis can be directly performed on the manual control command to obtain the relevant fields contained therein with respect to the target wind direction, and the target wind direction can be determined.
The device configuration information is used for determining the target wind direction, and may include, but is not limited to, an installation location of each hardware device in the server, a temperature environment required in an operation process, and the like, for example, the target wind direction may be determined according to temperature values in temperature sensors at different locations in the server, or may be determined according to installation locations of a network card, a RAID (redundant arrays of independent Disks) card, and the like.
In an embodiment of the application, after issuing the reverse control command to the fan driver to enable the fan driver to control the fan to rotate in the reverse direction, the method may further include: and updating the current wind direction in the preset storage address to be the target wind direction.
The method for controlling the wind direction of the fan provided by the embodiment of the application can further realize the updating of the current wind direction, so that the wind direction control can be continuously carried out when a new fan control command is received in the following process. Specifically, after the fan driver controls the fan to rotate in the reverse direction, that is, after the current fan wind direction control is completed, the current wind direction in the preset memory address may be further updated to the target wind direction, so that the target wind direction is taken as a new current wind direction. Therefore, when a new fan control command is received subsequently, the new current wind direction can be read to continue the wind direction control.
In an embodiment of the application, before the current wind direction in the preset storage address is updated to the target wind direction, the method may further include the following steps:
judging whether response information fed back by the fan driver is received;
and if so, executing the step of updating the current wind direction in the preset storage address to the target wind direction.
The embodiment of the application provides a method for updating a current wind direction in a preset storage address. Specifically, after the fan driver controls the fan to rotate in the reverse direction, before the current wind direction in the preset storage address is updated, it may be determined whether a response message fed back by the fan driver is received, where it is to be noted that the response message is a response message fed back to the bmc by the fan driver after the fan driver completes the reverse rotation, if the fan driver does not complete the reverse rotation, the response message will not be fed back to the bmc, and only after the fan driver completes the reverse rotation, the response message will be fed back. On the basis, if the baseboard management controller receives the response information fed back by the fan driver, the baseboard management controller can determine that the fan wind direction control is finished and the fan wind direction control is successful, and can execute the step of updating the current wind direction in the preset storage address to the target wind direction; otherwise, if the response information fed back by the fan driver is not received, it can be determined that the fan wind direction control is not completed or the control fails, and the step of updating the current wind direction in the preset storage address to the target wind direction is not executed.
In an embodiment of the application, the determining whether the response message fed back by the fan driver is received may include the following steps:
judging whether response information fed back by the fan driver is received within preset time;
if not, the reverse control instruction is issued to the fan driver again.
The embodiment of the application provides a method for realizing judgment of whether response information fed back by a fan driver is received. In the implementation process, the determining whether the response information fed back by the fan driver is received may specifically be determining whether the response information fed back by the fan driver is received within a preset time, that is, the response time may be preset, that is, the preset time is the above-mentioned time, if the corresponding time fed back by the fan driver is not received within the preset time, the default wind direction control fails, and at this time, the reverse control instruction may be issued to the fan driver again to implement the reverse control of the server fan. Of course, if the response information fed back by the fan driver can be received within the preset time, it may be determined that the wind direction control is successful this time, and the step of updating the current wind direction in the preset storage address to the target wind direction may be continuously performed. The specific value of the preset time does not affect the implementation of the technical scheme, and the specific value is set by a technician according to the actual requirement and can be set to be 2-3 seconds, which is not limited by the application.
In one embodiment of the present application, the fan wind direction control method may further include the steps of:
counting the number of times of no response;
and outputting alarm information when the non-response times reach the preset times.
In order to avoid a judgment error, the embodiment of the application may further determine whether the fan wind direction control is successful by performing statistics of the number of times of non-response. Specifically, when response information fed back by the fan driver is not received within a preset time, the number of non-response times is increased by 1, and if the number of non-response times reaches the preset number, it may be directly determined that the server is currently abnormal (including but not limited to fan abnormality, fan driver abnormality, and the like), and the wind direction control of the server fan cannot be realized, and at this time, an alarm information may be output to prompt the user to perform exception handling in time. Of course, if the non-response times do not reach the preset times, that is, if the response information fed back by the fan driver is received, the step of updating the current wind direction in the preset storage address to the target wind direction may be continuously performed, and the accumulated non-response times are cleared. Similarly, the specific value of the preset times does not affect the implementation of the technical scheme, and the specific value is set by a technician according to the actual requirement and can be set for 3 times, which is not limited by the application.
In an embodiment of the application, after issuing the reverse control command to the fan driver to enable the fan driver to control the fan to rotate in the reverse direction, the method may further include the following steps:
acquiring the actual wind direction of the fan;
judging whether the actual wind direction is consistent with the target wind direction;
if not, alarm information is output.
The fan wind direction control method provided by the embodiment of the application can further realize secondary verification about wind direction control so as to confirm whether the current fan wind direction control is successful. Specifically, after the fan driver controls the fan to rotate reversely, the actual wind direction of the server fan may be further obtained, and whether the actual wind direction is consistent with the target wind direction or not may be further determined, if the actual wind direction is consistent with the target wind direction, the wind direction control of this time is successful, otherwise, if the actual wind direction is inconsistent with the target wind direction, the wind direction control of this time is failed, and meanwhile, the current server abnormality (including but not limited to fan abnormality, fan driver abnormality, and the like) may be also determined, at this time, an alarm message may be output to prompt the user to perform abnormality processing in time.
On the basis of the above embodiments:
the application provides another fan wind direction control method, which comprises the following implementation processes:
(1) The BMC can determine the fan wind flow direction (namely target wind direction) required by the current server according to temperature sensors at the front end and the rear end of the server or components (such as a network card, a RAID card and the like) inserted into the current server by identifying the configuration of the server, and stores the fan wind flow direction in the EEprom of the BMC;
(2) The BMC may also manually set a fan airflow direction (i.e., a target airflow direction) required by the current server in a manual configuration manner, and generally may set the current fan airflow direction by sending an IPMI (Intelligent Platform Management Interface) command to the BMC and store the current fan airflow direction in an EEprom of the BMC;
(3) The BMC sends a reading command to a register address 0x32 (a preset storage address) of the fan control chip to obtain the current fan airflow direction (current wind direction) configured in the current fan control chip, and stores the current fan airflow direction into a virtual memory of the BMC;
(4) The BMC compares the fan airflow direction required to be set in the EEprom with the fan airflow direction in the current fan control chip, and checks whether the fan airflow direction and the current fan airflow direction are consistent;
(5) If the fan airflow direction in the BMC EEprom is consistent with the fan airflow direction in the current fan control chip, the BMC directly outputs a PWM (Pulse width modulation) signal to the fan control chip to continue to control the fan;
(6) If the fan air flow direction in the BMC EEprom is not consistent with the fan air flow direction in the current fan control chip, the BMC sends a control instruction to the address 0x34 of the fan control chip to control the fan blade to rotate so as to adapt to the air flow direction after the fan reverses;
(7) Waiting for 2-3 s, and changing the airflow direction value in the fan control chip after the fan blades finish direction conversion;
(8) The BMC confirms whether the wind flow direction in the fan control chip is consistent with the wind flow direction value in the EEprom in the BMC again;
(9) If the PWM signals are consistent with the PWM signals, the BMC outputs the PWM signals to the fan control chip, and fan control is continued.
Obviously, according to the fan wind direction control method provided by the embodiment of the application, the wind direction control of the fan in the server is realized through the substrate management controller, the target wind direction required in the current state can be determined according to the received fan control command, and whether the fan needs to be reversely controlled or not is determined by comparing the target wind direction with the current wind direction of the fan, so that the wind direction control of the server fan is realized.
The embodiment of the application provides a fan wind direction control device.
