[0027] First, the nouns involved in this application are explained:

[0028] Complex Programmable Logic Device (abbreviated as CPLD): A digital integrated circuit in which users can construct logic functions according to their needs. With the help of an integrated development software platform, corresponding target files are generated by methods such as schematic diagrams and hardware description languages, and the code is transmitted to the target chip through a download cable to achieve the design.

[0029] As an important heat dissipation device, the fan module is widely used in devices such as servers, storage devices, and switches. In the entire life cycle of the fan module from production, application, maintenance to re-application, the tracking of its asset information is crucial for product management.

[0030] There is usually a unique asset information label attached to the housing of each fan module, which contains asset information such as the serial number of the fan module. In the prior art, an electronic scanning gun is usually used to scan the asset information label to read the asset information of the fan module, and the asset information and the device identifier of the device where the fan module is located are stored in the asset management database correspondingly. However, the fan module has the characteristic of being frequently replaced in actual applications, and the information in the asset management database often cannot be updated in time, resulting in the inability of managers to track and manage the fan module according to the information in the management database.

[0031] Based on the above technical problems, the technical concept process of this application is as follows: how to provide a storage method for the asset information of the fan module to facilitate the tracking and management of the fan module.

[0032] Next, the technical solution of this application will be described in detail through specific embodiments. It should be noted that these specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0035] The server motherboard 12 includes a Baseboard Management Controller (BMC) 104 and a second complex programmable logic device 105. The BMC is connected to the second CPLD.

[0036] When the BMC of the server motherboard 12 detects the access of the fan module 11, it obtains the fan information corresponding to the fan module 11, generates a write information instruction carrying the fan information, and sends the write information instruction to the second CPLD.

[0037] The second CPLD of the server motherboard 12 is connected to the first CPLD of the fan module 11. After receiving the write information instruction sent by the BMC, the second CPLD sends it to the first CPLD.

[0038] The first CPLD of the fan module 11 obtains the fan information from the received write information instruction and stores the fan information in the memory 103. In this way, if the fan module 11 is subsequently replaced in other servers, it can obtain the fan information from the memory 103 and feedback it to the server when receiving a read request from the server, facilitating the tracking and management of the fan module.

Among them, the fan body 101 is connected to the first CPLD, and the first CPLD is connected to the memory 103.

[0040] The first CPLD is connected to the server motherboard and is used to receive a write information instruction sent by the server motherboard. Among them, the write information instruction is an instruction carrying the fan information generated by the server motherboard when detecting the access of the fan module and obtaining the fan information corresponding to the fan module.

[0041] The first CPLD obtains the fan information from the write information instruction and stores the fan information in the memory 103 to obtain the fan information from the memory 103 and feedback it when receiving a read request.

Compared with the prior art of using an electronic scanning gun to scan the asset information label of the fan module to read and store the asset information of the fan module, in this application, a CPLD and a memory are provided in the fan module, and the CPLD stores the fan information in the write information instruction in the memory according to the write information instruction sent by the server motherboard, so that devices such as servers can obtain the asset information of the fan module by accessing the memory, which is convenient for tracking and managing the fan module, and solves the problem that the storage method of the asset information of the fan module in the prior art is not conducive to tracking and managing the fan module.

[0044] Figure 3 It is a schematic structural diagram of another embodiment of the fan module provided by this application. Refer to Figure 3 , the fan module may include a fan body 101, a first Complex Programmable Logic Device 102, and a memory 103. Among them, the fan body 101 is connected to the first CPLD, and the first CPLD is connected to the memory 103.

[0045] The first CPLD is connected to the server motherboard and is used to receive the write information instruction sent by the server motherboard. Wherein, the write information instruction is an instruction carrying the fan information generated by the server motherboard when detecting the access of the fan module and obtaining the fan information corresponding to the fan module.

[0046] The first CPLD obtains the fan information from the write information instruction and stores the fan information in the memory 103, so as to obtain the fan information from the memory 103 and feedback it when receiving a read request.

[0047] Specifically, the first CPLD may include a first communication module 201, and the first communication module 201 is connected to the memory 103. The first CPLD is specifically used to control the first communication module 201 to be connected to the server motherboard when receiving the write information instruction of the server motherboard, so that the first communication module 201 obtains the fan information.

[0048] The first communication module 201 is used to send the obtained fan information to the memory 103, so that the memory 103 stores the fan information.

[0049] In this embodiment, the first CPLD obtains the write information instruction sent by the server motherboard through the first communication module 201, and obtains the fan information therefrom. Exemplarily, the first communication module 201 may be a Universal Asynchronous Receiver / Transmitter (UATR for short). When the first CPLD receives the write information instruction from the server motherboard, it controls the first communication module 201 to connect to the server motherboard. The first communication module 201 obtains the fan information and sends the fan information to the memory 103 so that the memory 103 stores the fan information.

[0050] Specifically, the first CPLD further includes a first fan control module 202, and the first fan control module 202 is connected to the fan body 101. The first communication module 201 is further configured to send a write completion message to the server motherboard after detecting that the fan information is stored in the memory 103, so that the server motherboard generates a fan control instruction according to the write completion message.

[0051] The first CPLD is further configured to control the first fan control module 202 to connect to the server motherboard when receiving the fan control instruction from the server motherboard, so that the server motherboard controls the fan body 101 through the first fan control module 202.

[0052] In this embodiment, after the first communication module 201 sends the fan information to the memory 103, it detects whether the fan information is completely stored in the memory 103. After determining that the fan information is completely stored, it generates a write completion message and sends the write completion message to the server motherboard.

[0053] The server motherboard generates a fan control instruction according to the write completion message and sends the fan control instruction to the first CPLD in the fan information. When the first CPLD receives the fan control instruction from the server motherboard, it controls the first fan control module 202 to connect to the server motherboard, so that the server motherboard controls the fan body 101 through the first fan control module 202.

[0054] In this embodiment, the server motherboard controls the fan body 101 through the first fan control module 202. Specifically, the first fan control module 202 outputs the current rotation speed of the fan body 101 to the server motherboard through a tachometer (TACH) signal. The server motherboard determines the target rotation speed of the fan according to the overall machine temperature status and outputs the target rotation speed value to the first fan control module 202 through a pulse width modulation (PWM) signal. The first fan control module 202 feeds back the target rotation speed value to the fan body 101 to achieve the rotation speed control of the fan body 101 by the server motherboard.

[0055] Specifically, the first CPLD further includes a first logic switch 203, and the first logic switch 203 is respectively connected to the first communication module 201 and the first fan control module 202.

[0056] The first CPLD controls the connection between the first communication module 201 and the server motherboard through the first logic switch 203, or controls the connection between the first fan control module 202 and the server motherboard.

[0057] In this embodiment, the first CPLD controls the connection between the first communication module 201 and the first fan control module 202 and the server motherboard through the first logic switch 203.

[0058] When the first CPLD receives the write information instruction from the server motherboard, it controls the first communication module 201 to be connected to the server motherboard through the first logic switch 203, so that the first communication module 201 can obtain the fan information.

[0059] When the first CPLD receives the fan control instruction from the server motherboard, it controls the first fan control module 202 to be connected to the server motherboard through the first logic switch 203, so that the server motherboard can control the fan body 101 through the first fan control module 202.

[0060] In this embodiment, the first CPLD controls the connection between the first communication module or the first fan control module and the server motherboard through the first logic switch, realizing the switching between the write information mode and the fan control mode. When the server motherboard writes fan information to the fan module, it switches to the write information mode. When the fan information writing is completed, the server motherboard resumes the rotation speed control of the fan module. In this way, the path of the server motherboard for controlling the rotation speed of the fan module can be borrowed to write the fan information, further solving the problem that the existing storage method of the asset information of the fan module is not conducive to the tracking and management of the fan module.

[0061] Figure 4 It is a schematic structural diagram of an embodiment of a server motherboard provided by this application. Refer toFigure 4 The server motherboard may include a baseboard management controller 104 and a second complex programmable logic device 105, where the BMC is connected to the second CPLD.

[0062] The BMC is configured to obtain fan information corresponding to the fan module when detecting the access of the fan module, generate a write information instruction carrying the fan information, and send the write information instruction to the second CPLD.

[0063] The second CPLD is connected to the first CPLD of the fan module, and is configured to send the received write information instruction sent by the BMC to the first CPLD, so that when the first CPLD receives the write information instruction, it obtains the fan information from the write information instruction and stores the fan information in the memory.

[0064] In this embodiment, when the baseboard management controller BMC of the server motherboard detects the access of the fan module, it obtains the fan information corresponding to the fan module. Exemplarily, the BMC can detect whether a fan module is accessed through the fan presence signal: when a fan module is accessed, the fan presence signal is a low-level signal; when no fan module is accessed, the fan presence signal is a high-level signal. Exemplarily, the BMC can obtain the fan information corresponding to the fan module from the asset management database according to the identifier of the server where the fan module is located.

[0065] The BMC generates a write information instruction carrying the fan information according to the obtained fan information corresponding to the fan module, and sends the write information instruction to the second CPLD. The second CPLD sends the received write information instruction to the first CPLD in the fan module. The first CPLD obtains the fan information from the write information instruction and stores the fan information in the memory. If the fan module is subsequently replaced in another server, it can obtain the fan information from the memory and feedback it to the server when receiving a read request from the server, which is convenient for tracking and managing the fan module.

[0066] In this embodiment, the server motherboard includes a baseboard management controller (BMC) and a second CPLD; the BMC is connected to the second CPLD; the BMC is configured to obtain the fan information corresponding to the fan module when detecting the access of the fan module, generate a write information instruction carrying the fan information, and send the write information instruction to the second CPLD; the second CPLD is connected to the first CPLD of the fan module, and is configured to send the received write information instruction sent by the BMC to the first CPLD, so that when the first CPLD receives the write information instruction, it obtains the fan information from the write information instruction and stores the fan information in the memory. Compared with the prior art of using an electronic scanning gun to scan the asset information label of the fan module to read and store the asset information of the fan module, when the CPLD in the server motherboard of this application detects the access of the fan module, it obtains the fan information corresponding to the fan module and sends the fan information to the fan module for storage, so that devices such as servers can obtain the asset information of the fan module by accessing the memory, which is convenient for tracking and managing the fan module, and solves the problem that the storage method of the asset information of the fan module in the prior art is not conducive to tracking and managing the fan module.

[0068] The BMC is configured to obtain the fan information corresponding to the fan module when detecting the access of the fan module, generate a write information instruction carrying the fan information, and send the write information instruction to the second CPLD.

[0069] The second CPLD is connected to the first CPLD of the fan module, and is configured to send the received write information instruction sent by the BMC to the first CPLD, so that when the first CPLD receives the write information instruction, it obtains the fan information from the write information instruction and stores the fan information in the memory.

[0070] Specifically, the second CPLD may include a second communication module 301. The second CPLD is specifically configured to control the second communication module 301 to connect to the first CPLD when obtaining the write information instruction sent by the BMC, so that the second communication module 301 sends the write information instruction to the first CPLD.

[0071] In this embodiment, the second CPLD sends a write information instruction to the first CPLD through the second communication module 301. Exemplarily, the second communication module 301 can be a Universal Asynchronous Receiver-Transmitter UATR. When the second CPLD obtains the write information instruction sent by the BMC, it controls the second communication module 301 to connect to the first CPLD, so as to send the write information instruction to the first CPLD through the second communication module 301.

[0072] Specifically, the second CPLD may further include a second fan control module 302. The BMC is further configured to generate a fan control instruction after receiving the write completion information sent by the first CPLD, and send the fan control instruction to the second CPLD.

[0073] The second CPLD is further configured to control the second fan control module 302 to connect to the first CPLD and send the fan control instruction to the first CPLD when receiving the fan control instruction, so that the BMC controls the fan module through the second fan control module 302.

[0074] In this embodiment, after storing the fan information, the first CPLD in the fan module generates a write completion information and sends the write completion information to the server motherboard. After receiving the write completion information sent by the first CPLD, the BMC generates a fan control instruction and sends the fan control instruction to the second CPLD.

[0075] When receiving the fan control instruction, the second CPLD controls the second fan control module 302 to connect to the first CPLD and sends the fan control instruction to the first CPLD. When receiving the fan control instruction of the server motherboard, the first CPLD controls the first fan control module 202 to connect to the server motherboard, and the server motherboard controls the fan body 101 through the first fan control module 202. Thus, the control of the fan module by the server motherboard is realized.

[0076] Specifically, the second CPLD may further include a second logic switch 303; the second logic switch 302 is respectively connected to the second communication module 301 and the second fan control module 302.

[0077] The second CPLD controls the second communication module 301 to connect to the first CPLD through the second logic switch 303, or controls the second fan control module 302 to connect to the first CPLD.

[0078] In this embodiment, the second CPLD controls the second communication module 301 and the second fan control module 302 to connect to the first CPLD of the fan module through the second logic switch 303.

[0079] When the second CPLD obtains the write information instruction sent by the BMC, it controls the second communication module 301 to connect to the first CPLD, so that the second communication module 301 sends the write information instruction to the first CPLD.

[0080] When the second CPLD receives the fan control instruction, it controls the second fan control module 302 to connect to the first CPLD, so as to send the fan control instruction to the first CPLD.

[0081] In this embodiment, the second CPLD controls the second communication module 301 or the second fan control module to connect to the first CPLD through the second logic switch, realizing the switching between the write information mode and the fan control mode. When the server motherboard writes fan information to the fan module, it switches to the write information mode. When the fan information writing is completed, the server motherboard resumes the speed control of the fan module. In this way, the writing path of the fan information can be borrowed by using the speed control path of the server motherboard for the fan module, further solving the problem that the storage method of the asset information of the fan module in the prior art is not conducive to the tracking and management of the fan module.

[0096] When receiving the fan control instruction, the second CPLD controls the second fan control module 302 to connect to the second fan connection terminal 402 to send the fan control instruction to the first CPLD. When receiving the fan control instruction from the server motherboard, the first CPLD controls the first fan control module 202 to connect to the first fan connection terminal 401 to enable the server motherboard to control the fan body 101 through the first fan control module 202.

[0097] Specifically, the first fan control module 202 obtains the TACH signal of the fan body 101 through the circuit board connector and outputs the current rotation speed of the fan body 101 to the BMC in the server motherboard through the second fan control module 302. The BMC in the server motherboard determines the target rotation speed of the fan according to the overall machine temperature status and outputs the target rotation speed value to the first fan control module 202 through the PWM signal. The first fan control module 202 feeds back the target rotation speed value to the fan body 101 to achieve the rotation speed control of the fan body 101 by the server motherboard.

[0098] In this embodiment, the adapter board 402 may further include a power adapter module located between the first fan connection terminal 401 and the first CPLD for converting the 12V power supply into the 3.3V power supply required by the first CPLD. The adapter board 402 may further include a TACH level isolation circuit and a PWM drive isolation circuit located between the second connection terminal 406 and the first CPLD for performing level matching between the fan body 101 and the first CPLD.

[0099] In this embodiment, when the CPLD in the server motherboard detects the access of the fan module, it obtains the fan information corresponding to the fan module and sends the fan information to the fan module through a write information instruction. The CPLD in the fan module stores the fan information in the write information instruction in the memory according to the write information instruction sent by the server motherboard, so that devices such as servers can obtain the asset information of the fan module by accessing the memory, which is convenient for tracking and managing the fan module, and solves the problem that the existing storage method of the asset information of the fan module is not conducive to tracking and managing the fan module.

[0103] Step S503: If the server motherboard detects the access of a fan module, it obtains the fan information corresponding to the fan module, generates a write information instruction carrying the fan information, switches to the write information mode, and sends the write information instruction to the fan module.

[0104] Step S504: The fan module switches to the write information mode according to the write information instruction sent by the server motherboard, obtains the fan information from the write information instruction, and stores the fan information.

[0105] Specifically, when the fan module is in the write information mode, the fan body operates at full speed.

[0106] Step S505: After the fan module detects that the fan information is stored, it generates a write completion message and sends the write completion message to the server motherboard.

[0107] Step S506: The server motherboard generates a fan control instruction according to the write completion message, switches to the fan control mode, and sends the fan control instruction to the fan module.

[0108] Step S507: The fan module switches to the fan control mode according to the fan control instruction sent by the server motherboard, so that the server motherboard can control the rotation speed of the fan module.
