Description
Technical Field
The invention relates to the field of servers, in particular to a method, a system, equipment and a storage medium for controlling a fan board.
Background
As shown in fig. 1, two fan boards in a 4U node are generally of the same type, and have no difference in hardware and structure, two same connectors are generally connected to a Host board card, and an actual installation position of the fan board connected to each connector needs to correspond to a preset position, that is, the fan board connected to the connector 1 needs to be placed on an upper layer, and the fan board connected to the connector 2 needs to be placed on a lower layer.
As shown in fig. 2, when numbering the fans of the fan board, the numbering is generally from top to bottom and from left to right, but the numbering is arranged on the server in the form of a label, which is visible to the user to facilitate the user to replace the fans, but the upper controller cannot sense the number. Thus, when the fan board 2 connected with the connector 1 is at the lower layer and the fan board 1 connected with the connector 2 is at the upper layer, the order of the fans corresponding to the on-position signal and the rotating speed signal fed back by the connector to the upper layer is opposite, that is, the fan on-position signal and the rotating speed signal (namely the on-position signal and the rotating speed signal of the fans numbered 5-9) of the fan board 2 are actually fed back by the connector 1 to the upper layer controller, but the upper layer controller still defaults that the fan on-position signal and the rotating speed signal received from the connector 1 are the on-position signal and the rotating speed signal of the fans numbered 0-4, which may cause the fan number corresponding to the warning given by the upper layer controller to be different from the number given on the server label when the fan on the fan board 2 fails, for example, when the fan numbered 5 on the fan board 2 fails, the BMC may give the fan numbered 1 failure, at this time, the alarming of the fault fan according to the number and the independent control of the rotating speed of a certain fan cannot be realized.
Therefore, when the server is assembled, the cables are usually distinguished through the cable label or from the HOST end connector type selection angle, an assembling person needs to carefully check the cable butt joint condition, but the fan board type is the same, the fan board end connector cannot be distinguished, the cable reverse insertion condition is very easy to occur, and the product maintenance and the usability are affected.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides a method for controlling a fan plate, as shown in fig. 3, which may include the steps of:
s1, receiving actual installation position data sent by the corresponding fan board connected by each connector;
s2, judging whether the actual installation position of the fan plate connected with the connector is a preset installation position according to the actual installation position data;
and S3, responding to the fact that the actual installation position of the fan board connected with the connector is not the preset installation position, and adjusting the sequence of the fan board control signals sent to the connector by using the control signals generated according to the actual installation position data.
The method provided by the invention realizes the fool-proof design of the fan plate by collecting the position information of the fan plate, can realize the normal sequencing control of the fan even if the cable is reversely inserted in the assembly process, and improves the usability and the maintainability of the product.
In some embodiments, in step S1, each connector on the control board may be connected to a fan board, and the connector is used to connect the fan board and the main board to achieve signal transmission, for example, the main board transmits a fan control signal (PWM signal) to the fan board, the fan board feeds back a presence signal (PRESENT signal) and an actual rotation speed signal (TACH signal) to the main board, and transmits data of the located height of the fan board collected by the sensor as actual mounting position data sent by the fan board or collects the distance between the fan board and the sidewall of the chassis as actual mounting position data sent by the fan board.
In some embodiments, as shown in fig. 4, taking 2 fan boards arranged up and down as an example, it is assumed that the fan board 1 is an upper fan board, the fan board 2 is a lower fan board, at this time, the fan board 1 is located at an upper layer, the shielding distance between the height sensor and the lower layer is greater than the distance between the lower fan board and the bottom of the chassis, and if the magnitude of the analog level output by the height sensor is proportional to the measured distance, the actual mounting position data returned by the fan board 1 is greater.
In some embodiments, the step S2, determining whether the actual installation position of the fan board connected to the connector is a preset installation position according to the actual installation position data, further includes:
and generating corresponding control signals according to the size of the plurality of actual mounting position data and a preset rule, and further judging whether the actual mounting position of the fan plate connected with the connector is a preset mounting position.
In some embodiments, generating the corresponding control signal according to the size of a number of pieces of actual installation position data and a preset rule further includes:
responding to the correspondence between the magnitude sequence and the preset sequence of the actual installation position data received by each connector, generating a high-level control signal, and confirming that the actual installation position of the fan plate connected with the connector is the preset installation position;
and generating a low-level control signal in response to the fact that the magnitude sequence and the preset sequence of the actual installation position data received by each connector do not correspond to each other, and confirming that the actual installation position of the fan plate connected with the connector is not the preset installation position.
Specifically, after the connector receives the actual mounting position data of the fan board, because the actual mounting position data corresponding to the fan boards of different mounting positions are different in size, the mounting position data can be sequenced according to the size of the actual mounting position data and compared with the preset sequence to determine whether the actual mounting position of the fan board connected with the connector is the preset mounting position. For example, the magnitude order of the mounting position data received by the connector may be set, and then it is determined whether the magnitude order of the mounting position data actually received by the connector is the set magnitude order, and further it is determined whether the actual mounting position of the fan board connected to the connector is the preset mounting position, and a corresponding control signal may be generated. For example, when it is set that the mounting position data received by the connector 1 needs to be larger than the mounting position data received by the connector 2, and the mounting position data received by the connector 2 is larger than the mounting position data received by the connector 3, it is determined that the actual mounting position of the fan board connected to the connector is the preset mounting position, and if the mounting position data actually received by the connectors 1, 2, and 3 is also the mounting position data received by the connector 1 needs to be larger than the mounting position data received by the connector 2, and the mounting position data received by the connector 2 is larger than the mounting position data received by the connector 3, it is determined that the actual mounting position of the fan board connected to the connector is the preset mounting position, and a high-level control signal is generated, and otherwise, a low-level control signal is generated.
In some embodiments, as shown in fig. 4 and 5, when the number of the connectors is two, the actual mounting position data received by the connectors may be input to two input terminals of a comparator respectively, that is, the actual mounting position data received by the connector 1 is input to the input terminal CH1, the actual mounting position data received by the connector 2 is input to the input terminal CH2, and then the comparator compares the magnitude sequence of the two input terminals to determine whether the actual mounting position of the fan board connected by the connectors is the preset mounting position, thereby generating the corresponding control signal. For example, it may be preset that when the input terminal CH1 is greater than the input terminal CH2, the actual mounting position of the fan board to which the connector is connected is determined to be the preset mounting position, and a control signal of a high level is generated, whereas a control signal of a low level is generated. In this way, when connector 1 is connected to upper fan board 1 and connector 2 is connected to lower fan board 2, since the actual mounting position data received by connector 1 is greater than the actual mounting position data received by connector 2, input CH1 is greater than input CH2, and the order of magnitude in which the mounting position data is actually received by the connectors is determined to be the set order of magnitude, the actual mounting position of the fan board connected to the connectors is determined to be the preset mounting position, and a high-level control signal is generated. On the contrary, when the connector 1 is connected to the lower fan board 2 and the connector 2 is connected to the upper fan board 1, the actual mounting position data received by the connector 1 is smaller than the actual mounting position data received by the connector 2, so the input terminal CH1 is smaller than the input terminal CH2, and the magnitude order of the mounting position data actually received by the connector is determined not to be the set magnitude order, so the actual mounting position of the fan board connected to the connector is determined not to be the preset mounting position, and a low-level control signal is generated.
In some embodiments, step S3, in response to the actual installation position of the fan board connected to the connector not being the preset installation position, adjusting the order of the fan board control signals sent to the connector by using the control signal generated according to the actual installation position data, further includes:
determining the actual mounting position of each fan plate according to the actual mounting position data in response to receiving a low-level control signal;
and sending the fan board control signal corresponding to the actual installation position of the fan board currently connected with the connector to the connector.
Specifically, when it is determined that the actual mounting position of the fan plate connected to the connector is not the preset mounting position, it is necessary to adjust the order of the fan plate control signals sent to the connector. In some embodiments, the actual mounting position of each of the fan boards may be determined according to the actual mounting position data, that is, the actual mounting position of the fan board connected to each connector is determined, and then a fan board control signal corresponding to the actual mounting position is sent to the connector.
Taking 3 connectors as an example, a fan board at a connection position 1 is preset in the connector 1, a first path of fan control signal is sent to the connector 1, a fan board at a connection position 2 is preset in the connector 2, a second path of fan control signal is sent to the connector 2, a fan board at a connection position 3 is preset in the connector 3, and a third path of fan control signal is sent to the connector 3. When the actual installation positions of the fan boards connected with the connectors 1, 2, and 3 are different from the preset installation position, a low-level signal is generated at this time according to the description, then the actual position sequence (for example, positions 3, 1, and 2) of the fan boards connected with the connectors 1, 2, and 3 is determined according to the actual installation position data received by the connectors 1, 2, and 3, then the sequence of the fan board control signals sent to the connectors is adjusted according to the actual corresponding installation position sequence, that is, the third fan control signal is sent to the connector 1, the first fan control signal is sent to the connector 2, and the second fan control signal is sent to the connector 3.
In some embodiments, if the actual mounting position of the fan board connected to the connector is determined to be the preset mounting position, the order of the fan board control signals sent to the connector does not need to be adjusted. Also taking the above 3 connectors as an example, when the actual installation positions of the fan boards connected to the connectors 1, 2, and 3 are the same as the preset installation positions, the first fan control signal is directly sent to the connector 1, the second fan control signal is sent to the connector 2, and the third fan control signal is sent to the connector 3.
In some embodiments, the method further comprises:
each connector is used for receiving an in-place signal and a rotating speed signal which are connected and sent by the corresponding fan plate;
and adjusting the reporting sequence of the in-place signal and the rotating speed signal received by each connector according to the actual mounting position of each fan plate.
Specifically, when it is determined that the actual mounting position of the fan plate connected to the connector is not the preset mounting position, the sequence of the fan on-position signal and the rotation speed signal reported to the superior controller needs to be adjusted. In some embodiments, the actual installation position of each fan plate may be determined according to the actual installation position data, that is, the actual installation position of the fan plate connected to each connector is determined, and then the fan in-place signal and the rotation speed signal corresponding to the actual installation position are reported to the upper-level controller. Also taking the above 3 connectors as an example, if the actual position sequence of the fan plates respectively connected to the connectors 1, 2, 3 determined according to the actual mounting position data received by the connectors 1, 2, 3 is positions 3, 1, 2, the reporting sequence is that the fan on-position signal and the rotation speed signal sent by the fan plate 1 received by the connector 2, the fan on-position signal and the rotation speed signal sent by the fan plate 2 received by the connector 3, and the fan on-position signal and the rotation speed signal sent by the fan plate 3 received by the connector 1 are in sequence.
In some embodiments, the method further comprises:
receiving a first path of fan plate control signal and a second path of fan plate control signal;
respectively inputting the first path of fan plate control signal and the second path of fan plate control signal to a first multiplexer connected with the first connector and a second multiplexer connected with the second connector;
controlling the first multiplexer to output a first path of fan board control signal to the first connector by default by utilizing the high-level control signal;
and controlling the second multiplexer to output a second path of fan plate control signal to the second connector by default by using a low level signal obtained by inverting the high level control signal.
In some embodiments, in response to the actual mounting position of the fan board connected to the connector not being a preset mounting position, adjusting an order of fan board control signals sent to the connector using a control signal generated from the actual mounting position data, further comprising:
controlling the output of the first multiplexer by using the low-level control signal, and adjusting the output of the first multiplexer to be the second path of fan plate control signal by the default first path of fan plate control signal;
and controlling the output of the second multiplexer to be adjusted to the first path of fan plate control signal by the default second path of fan plate control signal by using the high level signal obtained by inverting the low level control signal.
Specifically, as shown in fig. 4 and 5, when the number of connectors is 2, two paths of fan-board control signals, i.e., a first path of fan-board control signal and a second path of fan-board control signal, may be generated.
When the actual mounting position of the fan board to which connector 1 and connector 2 are connected corresponds to the preset mounting position, the comparator input CH1 receives an analog signal sent from the height sensor of fan board 1, CH2 receives an analog signal sent from the height sensor of fan board 2, and when CH1> CH2, the digital logic level output by the analog comparator is high. The CPLD receives that the output signal of the analog comparator is high level, judges that the cable connection is in a normal corresponding relationship at the moment, namely the FAN plate 1 is connected to the connector 1 corresponding to the HOST end, judges that the in-place signal and the rotating speed signal of the received FAN are the same as the actual FAN position, namely HOST _ FAN0_ PRESENT corresponds to FAN0_ PRESENT, HOST _ FAN0_ TACH corresponds to FAN0_ TACH, and reports the rotating speed and the in-place information according to a normal sequence when the BMC acquires the rotating speed and the in-place information. Connecting PWM control signals of fans at corresponding positions of an upper layer and a lower layer to an input end of a MUX (first multiplexer), connecting an output end of the MUX to a fan board connector at a corresponding HOST end, controlling a PWM MUX (second multiplexer) control pin of a corresponding fan board 2 connector by the output of an analog comparator after negation, assuming that the control pin is an input signal which is output as CH1 by the MUX when the control pin is high level, and outputting as an input signal of CH2 by the MUX when the control pin is low level, wherein the PWM signal received by the fan connector 1 is PWM0-4 (first fan board control signal) sent by BMC, and the PWM signal received by the fan connector 2 is PWM5-9 (second fan board control signal) sent by the BMC, and the PWM control signals are consistent with the actual connection condition.
When the actual mounting position of the fan board to which the connector 1 and the connector 2 are connected does not correspond to the preset mounting position, that is, the connector 1 is connected to the fan board 2, and the connector 2 is connected to the fan board 1. The analog differential comparator input CH1 receives the analog signal from the height sensor of fan board 2, CH2 receives the analog signal from the height sensor of fan board 1, CH1< CH2, and the digital logic level of the analog comparator output is low. The CPLD receives that the output signal of the analog comparator is low level, judges that the cable connection is opposite corresponding relation at the moment, namely the FAN plate 1 is connected to the connector 2 corresponding to the HOST end, judges that the received FAN in-place signal and the received rotating speed signal are opposite to the actual vertical position of the FAN at the moment, namely HOST _ FAN0_ PRESENT corresponds to FAN5_ PRESENT, HOST _ FAN0_ TACH corresponds to FAN5_ TACH, and reports the rotating speed signal and the in-place signal according to the opposite logic sequence of the vertical position when the BMC acquires the rotating speed and the in-place information. Connecting PWM control signals of fans at corresponding positions of an upper layer and a lower layer to an input end of a MUX (multiplexer), connecting an output end of the MUX to a fan board connector at a corresponding HOST end, controlling a PWM MUX control pin of a connector corresponding to a fan board 1 by the output of an analog comparator through negation, controlling the PWM MUX control pin of a connector corresponding to a fan board 2 by the output of the analog comparator through negation, assuming that the control pin is a high level and is an input signal which is output as CH1 by the corresponding MUX, outputting an input signal which is output as CH2 by the corresponding MUX when the control pin is a low level, at the moment, the PWM signal received by the fan connector 1 is PWM5-9 (a second fan board control signal) sent by BMC, and the PWM signal received by the fan connector 2 is PWM0-4 (a first fan board control signal) sent by the BMC, wherein the PWM control signals conform to the actual connection condition.
Thus, in this embodiment, the CPLD is used to determine and distinguish the logical correspondence between the fan speed and the in-place signal, so that the speed information and the in-place information received by the BMC are consistent with the current actual connection state, the PWM is logically determined and output by the MUX, and the BMC and the CPLD can directly perform control and transparent transmission without special processing.
It should be noted that the functions of the comparator and the MUX controller shown in fig. 4 and 5 can be implemented by the CPLD. And the judgment and the distinction of the logical correspondence between the fan rotating speed and the on-site signal can also be realized by the MUX controller.
According to the scheme provided by the invention, the position data is acquired through the board card, and the effect that the serial number of the fan is not changed when the cable is inserted forwards or backwards is realized. The requirement that the production line needs to distinguish connection of the upper and lower fan plates from a cable or an HOST connector is reduced, and the problem of regulation and control and the problem of maintenance of a follow-up fan caused by reverse connection of the production line cable are prevented. The mode that the traditional fan boards on different layers are distinguished through cable label identification or cable color or are distinguished from the connector model selection angle of two fan boards at the HOST board end is changed, the condition that assembling personnel need strictly distinguish the corresponding relation between a cable and the upper and lower fan boards according to a product instruction book is avoided, time and labor are wasted, and the problem of mixed insertion cannot be completely avoided.
