Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the present invention provides a method for controlling a fan error reporting lamp of a server, the method having a corresponding fan error reporting system, the fan error reporting system having a BMC1, a CPLD (Complex Programmable Logic Device)2, a fan error reporting lamp 3 and a fan 4, and the method comprising:
s1: the BMC1 monitors the operation conditions of the fans 4 in real time;
s2: judging whether a fan 4 with error reporting exists;
s3: if so, acquiring first position information of the error-reporting fan 4, and generating error-reporting information;
s4: the error reporting information is sent to the CPLD2 through an I2C channel, the second position information of the error reporting fan 4 is obtained after being analyzed by the CPLD2, and the light-up instruction information is generated according to the second position information to light up the fan error reporting light 3 corresponding to the error reporting fan 4.
In the embodiment of the present invention, the BMC1 obtains the operation condition of the fan 4 through the TACH signal transmitted by the fan to the BMC1 and the PWM signal transmitted by the server to the BMC 1. The BMC1 determines whether there is an error-reported fan 4 according to the TACH signal and the PWM signal. If the BMC1 determines that there is an error-reported fan 4, the first position information of the error-reported fan 4 is acquired, and error-reported information is generated. The BMC1 and the CPLD2 transmit signals through an I2C (Inter-Integrated Circuit) channel, and error reporting information is an I2C signal. After the CPLD2 analyzes the I2C signal, the second position information of the error-reporting fan 4 is obtained (i.e., the CPLD2 obtains the specific position information of the error-reporting fan 4), and sends the lighting instruction information to the corresponding fan error-reporting lamp 3 to light the fan error-reporting lamp 3. For example, taking a fan error reporting system with 8 fans as an example, the I2C signal is 8 bits of data, where bit0 represents the first fan, and bit1 represents the second fan. Each bit represents a fan, and if the 8 bits are all at the low level 00000000, the CPLD2 resolves that all 8 fans are operating normally. If a bit or bits in the I2C signal are set to 1, it represents that there is an error in the fan 4 corresponding to the bit. For example, if the data of 8 bits transmitted by the CPLD2 and received the I2C signal transmitted by the BMC1 is 00100001, it indicates that there is an error in the first fan and the sixth fan. In summary, in order to fully save the GPIO interface of the BMC1, the I2C signal of the BMC1 (only two GPIO interfaces are needed, and this can be achieved regardless of the number of the fans 4) is transmitted to the CPLD2 of the motherboard, and after the CPLD2 decodes the I2C signal, the fan error-reporting lamp 3 at the position of the fan 4 that finally reports an error is made to emit light. Therefore, under the condition that a user intuitively obtains a corresponding fan error reporting prompt and timely maintains the damaged fan 4, the number of interfaces of the BMC1 occupied by a server fan error reporting mechanism is greatly reduced.
Further, after the step S2 of determining whether there is an error-reporting fan, the method includes:
s3: if not, the BMC1 generates fan operation information and sends the fan operation information to the CPLD2, the fan operation information is analyzed by the CPLD2 to generate standing instruction information, and the fan error-reporting lamps 3 are all kept in an off state.
In the embodiment of the present invention, if the BMC1 determines that there is no error-reporting fan 4, the fan error-reporting lamp 3 remains off.
Further, the BMC1 and CPLD2 transmit signals over the I2C channel.
Further, after the step S4 of sending the error information to the CPLD2 through the I2C channel, obtaining second position information of the error-reported fan 4 after the analysis by the CPLD2, generating lighting instruction information according to the second position information, and lighting the fan error-reporting lamp 3 corresponding to the error-reported fan 4, the method includes:
s5: acquiring the number information of the fans of the server in real time, and judging whether the number of the fans 4 is changed or not;
s6: if yes, acquiring the current quantity information of the fans 4;
s7: and changing the digit of the error information according to the current quantity information, so that the digit of the error information is consistent with the numerical value of the current quantity information.
In the embodiment of the present invention, for example, the fan error reporting system has 8 fans 4, and only the BMC1 needs to transmit the content of 8 bits to the CPLD2 through the I2C channel. If the number of fans of the server is changed from 8 to 16, the BMC1 can easily realize the alarm prompt of 16 fans 4 by only transmitting the content of 16 bits to the CPLD 2. The problem that the overall design of the server needs to be changed when the number of the fans 4 is changed in the traditional design (namely, the original interface of the BMC1 needs to be changed from being connected with other components to being connected with the fans 4) is avoided, and the modification cost of modifying a server heat dissipation system is reduced. In addition, the number of the fans can be increased or reduced at any time through the data customization of the I2C, and the fan error-reporting prompting function can be well realized only by adjusting the firmware of the CPLD 2. The programmable logic device CPLD2 is very flexible, is a very simple and convenient implementation mode, provides guarantee for random increase of the number of the fans 4, and is very practical.
Referring to fig. 3, the present invention further provides a control device for a fan error-reporting lamp of a server, including:
the monitoring module A is used for monitoring the running conditions of the fans in real time by the BMC 1;
the first judgment module B is used for judging whether the fan 4 with the error report exists or not;
the error reporting module C is used for acquiring first position information of the error reporting fan 4 and generating error reporting information if the first position information is positive;
and the lighting module D is used for sending the error reporting information to the CPLD2 through an I2C channel, obtaining second position information of the error reporting fan after the second position information is analyzed by the CPLD2, generating lighting instruction information according to the second position information, and lighting the fan error reporting lamp 3 corresponding to the error reporting fan.
In the embodiment of the present invention, the BMC1 obtains the operation condition of the fan 4 through the TACH signal transmitted by the fan to the BMC1 and the PWM signal transmitted by the server to the BMC 1. The BMC1 determines whether there is an error-reported fan 4 according to the TACH signal and the PWM signal. If the BMC1 determines that there is an error-reported fan 4, the first position information of the error-reported fan 4 is acquired, and error-reported information is generated. The BMC1 and the CPLD2 transmit signals through an I2C (Inter-Integrated Circuit) channel, and error reporting information is an I2C signal. After the CPLD2 analyzes the I2C signal, the second position information of the error-reporting fan 4 is obtained (i.e., the CPLD2 obtains the specific position information of the error-reporting fan 4), and sends the lighting instruction information to the corresponding fan error-reporting lamp 3 to light the fan error-reporting lamp 3. For example, taking a fan error reporting system with 8 fans as an example, the I2C signal is 8 bits of data, where bit0 represents the first fan, and bit1 represents the second fan. Each bit represents a fan, and if the 8 bits are all at the low level 00000000, the CPLD2 resolves that all 8 fans are operating normally. If a bit or bits in the I2C signal are set to 1, it represents that there is an error in the fan 4 corresponding to the bit. For example, if the data of 8 bits transmitted by the CPLD2 and received the I2C signal transmitted by the BMC1 is 00100001, it indicates that there is an error in the first fan and the sixth fan. In summary, in order to fully save the GPIO interface of the BMC1, the I2C signal of the BMC1 (only two GPIO interfaces are needed, and this can be achieved regardless of the number of the fans 4) is transmitted to the CPLD2 of the motherboard, and after the CPLD2 decodes the I2C signal, the fan error-reporting lamp 3 at the position of the fan 4 that finally reports an error is made to emit light. Therefore, under the condition that a user intuitively obtains a corresponding fan error reporting prompt and timely maintains the damaged fan 4, the number of interfaces of the BMC1 occupied by a server fan error reporting mechanism is greatly reduced.
Further, the control device of the fan error-reporting lamp of the server further comprises:
and the extinguishing module is used for generating fan operation information and sending the fan operation information to the CPLD2 by the BMC1 if the fan operation information is not, generating standing instruction information after the fan operation information is analyzed by the CPLD2, and keeping the fan error-reporting lamp 3 in an extinguishing state.
In the embodiment of the present invention, if the BMC1 determines that there is no error-reporting fan 4, the fan error-reporting lamp 3 remains off.
Preferably, the control device for the fan error light of the server further includes:

and the resetting module is used for changing the digit of the error reporting information according to the current quantity information, so that the digit of the error reporting information is consistent with the numerical value of the current quantity information.
In the embodiment of the present invention, for example, the fan error reporting system has 8 fans 4, and only the BMC1 needs to transmit the content of 8 bits to the CPLD2 through the I2C channel. If the number of fans of the server is changed from 8 to 16, the BMC1 can easily realize the alarm prompt of 16 fans 4 by only transmitting the content of 16 bits to the CPLD 2. The problem that the overall design of the server needs to be changed when the number of the fans 4 is changed in the traditional design (namely, the original interface of the BMC1 needs to be changed from being connected with other components to being connected with the fans 4) is avoided, and the modification cost of modifying a server heat dissipation system is reduced. In addition, the number of the fans can be increased or reduced at any time through the data customization of the I2C, and the fan error-reporting prompting function can be well realized only by adjusting the firmware of the CPLD 2. The programmable logic device CPLD2 is very flexible, is a very simple and convenient implementation mode, provides guarantee for random increase of the number of the fans 4, and is very practical.
