[0093] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0094] A host bus adapter (HBA) card can be used for various bus interconnections, but the HBA card is mainly used for the connection between a server and a storage device. An FC (Fibre Channel) HBA card is a type of HBA card, and uses optical fibers as the connection medium. Since the FC HBA card needs to be connected to an optical fiber, an optical module (SFP) is needed to connect the optical fiber and to transmit and convert optical signals. In recent years, with the development of the Internet and information technology, the demand for storage is increasing, and HBA cards are increasingly widely used in enterprise and data center businesses. In the process of using the optical module, the operating conditions of the optical module, such as voltage, connection rate, optical module temperature, and the like, need to be determined according to the optical module information, so as to determine the stability and health status of the optical module. The basic information of the optical module, such as the manufacturer and the model, also needs to be paid attention to, so as to facilitate asset management and information collection and component replacement processing in the fault scenario. The acquisition of optical module information generally depends on the device in which the optical module is located, for example, the HBA card.

[0095] The optical module information of the SFP is stored in the EEPROM of the SFP. The current BMC acquires the optical module information through the HBA card, as shown in FIG. 1. The HBA card can acquire the optical module information from the optical module (SFP) through an IIC (Inter-Integrated Circuit) bus. The HBA card provides a PLDM (Platform Level Data Model) over MCTP (Management Component Transport Protocol) channel. The BMC sends a standard PLDM command through the PLDM over MCTP channel to acquire the optical module information and to realize the monitoring of the SFP. In the above scheme, the BMC acquires the SFP information completely depending on the HBA card. However, the main function of the HBA card is not SFP monitoring, and the HBA card has a large load when working. Therefore, the timeliness and richness of the SFP information acquired by the BMC cannot be guaranteed. If the working state of the HBA card is abnormal, the BMC cannot monitor the SFP information at all. At the same time, the current HBA card does not support monitoring of the optical module, and cannot acquire various required optical module information, which limits the acquisition of the optical module information by the BMC and lacks timeliness and richness.

[0096] Based on the above, some embodiments of the present application provide an optical module management method, a new data path is designed to obtain optical module information, through the data path, the BMC can directly interact with the optical module and obtain all information of the optical module. The new path is constructed from the hardware level, the BMC directly accesses the IIC bus of the optical module, reads the EEPROM in the SFP through the bus to obtain the optical module information. To achieve more reliable monitoring of the optical module, the obtained optical module information has the effect of timeliness and richness.

[0097] According to some embodiments of the present application, an optical module management method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from here.

[0098] In some embodiments of the present application, an optical module management method is provided, which is applied to a programmable logic device. FIG. 2 is a flowchart of an optical module management method according to some embodiments of the present application, as shown in FIG. 2, the flow includes the following steps.

[0099] Step S201, obtaining the in-place information of the optical module, and determining whether the optical module is in place according to the in-place information.

[0100] Specifically, the programmable logic device is, for example: complex programmable logic device (CPLD), programmable logic controller (PLC), and field programmable logic gate array (FPGA), etc.

[0101] The programmable logic device obtains the in-place information of the optical module, for example: the programmable logic device can read the in-place information from the baseboard management controller, the in-place information in the baseboard management controller is obtained from the HBA card; the programmable logic device can also set a hardware link with the optical module, and obtain the in-place information of the optical module through the hardware link. According to the in-place information, it is determined whether the optical module is in place.

[0102] Step S202, in the case that the optical module is in place and the communication bus between the optical module is idle, obtaining the optical module information of the optical module through the communication bus.

[0103] Specifically, the programmable logic device often shares the same communication bus with the HBA card to communicate with the optical module (SFP). In order to avoid data transmission errors, the programmable logic device and the HBA card cannot simultaneously use the communication bus for communication. When the HBA card uses the communication bus, the programmable logic device cannot use it. The communication bus is, for example, an IIC bus. In addition, the present application can also be applied to other components with optical modules outside the HBA card, such as HCA (Host Channel Adapter, Host Channel Adapter) network cards, etc.

[0104] The programmable logic device determines whether the communication bus is idle by detecting the level state of the communication bus. For example, if the level state of the communication bus is high for a long time, it indicates that the communication bus is idle.

[0105] The programmable logic device sends a command to access and read the optical module information stored in the EEPROM of the optical module through the communication bus when it is determined that the optical module is in place and the communication bus between the optical module is idle.

[0106] In step S203, the optical module information is transmitted to the baseboard management controller to instruct the baseboard management controller to generate and execute an optical module management strategy according to the optical module information.

[0107] Specifically, after the programmable logic device obtains the optical module information, it can directly or periodically transmit the optical module information to the baseboard management controller through the communication link between the programmable logic device and the baseboard management controller. The specific transmission time is determined according to the actual situation.

[0108] After receiving the optical module information, the baseboard management controller determines the state of the optical module according to the optical module information. If the optical module state is abnormal, it generates and executes a corresponding optical module management strategy. For example, if the temperature of the optical module is too high, the optical module management strategy is to increase the speed of the cooling fan; if a fault code appears in the optical module information, the optical module management strategy is to output alarm information containing the fault code, etc.

[0109] The optical module management method provided by some embodiments of the present application can be used to obtain the optical module information of the optical module when the optical module is in place and the communication bus between the optical module is idle. The programmable logic device establishes a monitoring channel from the baseboard management controller to the optical module, making it more timely and comprehensive to obtain the optical module information, providing more means and information for monitoring and fault diagnosis of the optical module state, and enhancing the product competitiveness. The problem of lack of timeliness and richness of the optical module information obtained by the baseboard management controller is solved.

[0110] In some embodiments, the in-place information of the optical module is obtained, and whether the optical module is in place is determined according to the in-place information, comprising:

[0111] Query the in-place information of the optical module from the baseboard management controller;

[0112] Alternatively, obtain the in-place information from the optical module through a hardware link between the programmable logic device and the optical module.

[0113] Determine whether the optical module is in place according to the in-place information.

[0114] Specifically, the programmable logic device can obtain the in-place information of the optical module in two ways. One way is that the programmable logic device reads the in-place information from the baseboard management controller, and the in-place information in the baseboard management controller is obtained from the HBA card. The other way is that the programmable logic device and the optical module are provided with a hardware link, and the in-place information of the optical module is obtained through the hardware link.

[0115] The first way is shown in FIG. 3. The HBA card obtains the in-place information of the optical module from the optical module through an IIC bus, and the BMC obtains the in-place information of the optical module from the HBA card through the PLDM over MCTP out-of-band management mode provided by the HBA card. After receiving the optical module in-place state query request sent by the CPLD, the BMC sends the in-place state to the CPLD through the IIC bus, wherein in the IIC bus, the CPLD is the master device (Master) and the BMC is the slave device (Slave). After receiving the in-place signal of the optical module, the CPLD starts to perform the optical module information acquisition operation.

[0116] The in-place state of the optical module does not necessarily have to be obtained by the BMC from the HBA card through the out-of-band mode. A hardware link from the optical module slot to the CPLD can be directly established for the CPLD to monitor the in-place signal of the optical module. Therefore, the second way is shown in FIG. 4. A hardware link is established between the programmable logic device and the optical module. The CPLD no longer requests the BMC side to obtain the in-place state of the optical module, and is changed to the CPLD directly detecting the in-place information of the optical module through the hardware link. The in-place information is, for example, a PRSNT (Present, in place) signal. The PRSNT signal is used to indicate whether the optical module has been correctly inserted into the system. In the second way, the BMC no longer depends on the out-of-band management function provided by the HBA card to obtain and monitor the optical module information, and the optical module and the HBA card can be completely decoupled.

[0117] The programmable logic device determines whether the optical module is in place according to the in-place information. For example, if the in-place information is the PRSNT signal, and if the PRSNT signal is high, it is determined that the optical module is in place. If the optical module is not in place, the programmable logic device keeps obtaining the in-place information until it is determined that the optical module is in place.

[0118] In some embodiments of the present application, the programmable logic device queries the in-place information of the optical module from the baseboard management controller or through the hardware link; according to the in-place information, it determines whether the optical module is in place. Only when the optical module is in place, the optical module information is obtained, so as to avoid wasting communication resources.

[0119] In some embodiments, the optical module information of the optical module is obtained through the communication bus under the condition that the optical module is in place and the communication bus between the optical module is idle, including:

[0120] Obtaining the level signal of the communication bus;

[0121] If the level signal is high, it is determined that the communication bus is idle, and the logic is switched to become the master device of the optical module.

[0122] The optical module information of the optical module is actively obtained through the communication bus.

[0123] Specifically, the programmable logic device often shares the same communication bus with the HBA card, and communicates with the optical module (SFP), and the communication bus is, for example, IIC bus. Considering that the IIC bus of the optical module is occupied by the HBA card, the BMC and the HBA card cannot access the IIC bus at the same time, the present application designs and edits the CPLD to determine whether the IIC bus is idle, and then obtains the optical module information through the IIC bus when the IIC bus is idle and the optical module is in place. Therefore, the present application stipulates in the IIC bus that the master device and the slave device will first query the IIC bus level when initiating an access request to judge whether it is in an idle state. The above design ensures that the CPLD and the HBA card access the optical module in time sharing, and does not cause bus congestion to affect the normal work of the HBA card.

[0124] The programmable logic device polls the idle state of the IIC bus between the HBA card and the optical module; if the IIC bus is occupied, the polling is maintained; if the bus is idle, the CPLD performs logic switching to make itself the master device of the IIC bus, sends a command to obtain the optical module information, and after obtaining the optical module information, does not analyze it, but directly forwards the information to the BMC through another IIC bus. The steps include:

[0125] The programmable logic device obtains the level signal of the communication bus, monitors the IIC bus level signal between the HBA card and the optical module, and judges whether the bus is occupied. If the level signal is high, it is determined that the communication bus is idle. The programmable logic device performs logic switching to switch the master device of the IIC bus from the HBA card to the programmable logic device, and the programmable logic device becomes the master device of the optical module.

[0126] When the programmable logic device becomes the master of the IIC bus of the optical module, the programmable logic device actively sends a command to access and read the optical module information stored in the EEPROM of the optical module through the IIC bus. Then, the programmable logic device acts as the master and the BMC acts as the slave. The programmable logic device synchronizes the acquired optical module information to the BMC in a timely manner.

[0127] If the programmable logic device acquires the in-place information of the optical module in the manner corresponding to FIG. 3, the process of the programmable logic device acquiring the optical module information is shown in FIG. 5: the HBA card queries the SFP in-place state (continuous query); the optical module returns the SFP in-place state; the BMC queries the SFP in-place state from the HBA card (continuous query); the HBA card returns the SFP in-place state to the BMC; the programmable logic device queries the SFP in-place state (continuous query); the BMC returns the SFP in-place state to the programmable logic device; the programmable logic device acquires the SFP information if the SFP is in place and the IIC bus is idle; the optical module returns the SFP information to the programmable logic device; and the programmable logic device forwards the SFP information to the BMC.

[0128] If the programmable logic device acquires the in-place information of the optical module in the manner corresponding to FIG. 4, the process of the programmable logic device acquiring the optical module information is shown in FIG. 6: the programmable logic device queries the SFP in-place state from the optical module (continuous query); the optical module returns the SFP in-place state to the programmable logic device; the programmable logic device acquires the SFP information if the SFP is in place and the IIC bus is idle; the optical module returns the SFP information to the programmable logic device; and the programmable logic device forwards the SFP information to the BMC.

[0129] In some embodiments of the present application, the programmable logic device checks whether the communication bus is idle according to the level signal of the communication bus. When the communication bus is idle, the programmable logic device acquires the optical module information through the communication bus. This avoids affecting the use of the communication bus by other devices.

[0130] In some embodiments, the active acquisition of the optical module information of the optical module through the communication bus includes:

[0131] acquiring a first optical module information acquisition instruction from the BMC;

[0132] determining an optical module information requirement according to the first optical module information acquisition instruction;

[0133] generating a second optical module information acquisition instruction according to the optical module information requirement, and sending the second optical module information acquisition instruction to the optical module, wherein the second optical module information acquisition instruction is used to instruct the optical module to return the optical module information corresponding to the optical module information requirement;

[0134] The optical module information is received through the communication bus.

[0135] Specifically, the baseboard management controller can send a first optical module information acquisition instruction to the programmable logic device through the IIC bus between the programmable logic device, and inform the programmable logic device of the current optical module information requirement, for example, the requirement of acquiring the voltage, temperature and connection rate of the optical module, and the requirement of acquiring the manufacturer and model of the optical module.

[0136] The programmable logic device generates a second optical module information acquisition instruction according to the optical module information requirement, and sends the second optical module information acquisition instruction to the optical module through the communication bus to read the optical module information stored in the EEPROM of the optical module. The optical module information is received through the communication bus.

[0137] In some embodiments, the transmission of the optical module information to the baseboard management controller comprises:

[0138] The first data field in the optical module information is acquired, wherein the first data field comprises a name field and an attribute field of the optical module;

[0139] According to a preset mapping relationship, first index information corresponding to the first data field of the optical module is determined, wherein the preset mapping relationship comprises a mapping relationship between the data field and the index of the optical module, and the first index information comprises a name index and an attribute index corresponding to the optical module;

[0140] The optical module information and the corresponding first index information are sent to the baseboard management controller and saved to a first database;

[0141] The method further comprises:

[0142] When the optical module is in place and the communication bus between the optical module is idle, new optical module information is acquired again through the communication bus;

[0143] A second data field in the new optical module information is acquired;

[0144] According to the preset mapping relationship, second index information corresponding to the second data field is determined;

[0145] The new optical module information is compared with the optical module information corresponding to the second index information in the first database to determine whether there is a change in the optical module information;

[0146] If the changed optical module information exists, the optical module information in the first database is updated according to the changed optical module information and the second index information corresponding to the changed optical module information, an asynchronous monitoring event is triggered, and the changed optical module information and the second index information corresponding to the changed optical module information are sent to the baseboard management controller, where the asynchronous monitoring event is sent to the programmable logic device by the baseboard management controller and is used for monitoring whether the optical module information on the programmable logic device side is changed.

[0147] Specifically, the number of interfaces in some switches exceeds 256, that is, there are more than 256 optical modules, and the BMC needs to obtain the optical module information saved in the EEPROM of all the optical modules. The prior art generally uses the slow I2C bus to read, and when the number of optical modules is not large, for example, only a few, the defect in reading speed is not obvious, but when the number of optical modules in the system reaches hundreds, it takes a long time to read all the technical parameters and other data of the optical modules, which is usually not allowed in actual application scenarios, for example, in a fast restart scenario.

[0148] Therefore, the present application can create a first database in the external memory of the programmable logic device, create a second database in the baseboard management controller, save the optical module information to the first database first, and synchronize the optical module information of the first database to the second database. Subsequently, if the optical module information in the first database changes, only the change information needs to be sent to the baseboard management controller, reducing the amount of data transmitted. As shown in FIG. 7, the programmable logic device creates a first database, and the baseboard management controller creates a second database. The programmable logic device saves the optical module information and the corresponding first index information to the first database, and sends the optical module information and the corresponding first index information to the baseboard management controller through the IIC bus, and then the baseboard management controller saves the optical module information and the corresponding first index information to the second database. The specific steps include:

[0149] The programmable logic device obtains the first data field in the optical module information, the first data field including a name field and an attribute field of the optical module, for example: the optical module is classified according to the packaging form, and common ones are SFP, SFF (Small Form-factor Pluggable, small form-factor pluggable module), etc. The name field is the name of the optical module, and the name field is: SFP1, SFP2, …, SFF1, SFF2, etc. The attribute field includes voltage, connection rate, temperature, manufacturer, model, error code, etc.

[0150] The preset mapping relationship includes a mapping relationship between the name field and the name index, and a mapping relationship between the attribute field and the attribute index, for example: the mapping relationship between the name field and the name index is shown in Table 1, and the mapping relationship between the attribute field and the attribute index is shown in Table 2.

[0151] Mapping relationship between name index and attribute index

[0152] Mapping relationship between attribute field and attribute index

[0153] According to the preset mapping relationship, the first index information corresponding to the first data field of the optical module is determined, and the first index information includes the name index and the attribute index corresponding to the optical module, for example, the first index information corresponding to the temperature of SFP1 is 1c, and the first index information corresponding to the error code of SFF2 is 4f.

[0154] The optical module information and the corresponding first index information are sent to the baseboard management controller through the IIC bus, and are saved to the first database by the baseboard management controller.

[0155] In addition, the programmable logic device can obtain the information of each optical module every time or at a fixed time, update the data of the first database if the obtained information is inconsistent with the first database, trigger an asynchronous monitoring event, and synchronize the changed data to the second database of the BMC. The steps include:

[0156] The programmable logic device obtains new optical module information through the communication bus again under the condition that the optical module is in place and the communication bus between the optical module is idle; obtains a second data field in the new optical module information; determines second index information corresponding to the second data field according to the preset mapping relationship; compares the new optical module information with the optical module information corresponding to the second index information in the first database, and judges whether there is a change in the optical module information.

[0157] The first database and the second database can use a combination of active request response mechanism and asynchronous monitoring response mechanism to realize real-time synchronization of data. If there is a change in the optical module information, the optical module information in the first database is updated according to the changed optical module information and the second index information corresponding to the changed optical module information, an asynchronous monitoring event is triggered, and the changed optical module information and the second index information corresponding to the changed optical module information are sent to the baseboard management controller. The asynchronous monitoring event is issued by the baseboard management controller to the programmable logic device, and is used to monitor whether the optical module information on the programmable logic device side is changed. Similarly, the same technical effect can be achieved by using a subscription mechanism, that is, the baseboard management controller subscribes to the data in the first database, and the programmable logic device pushes the changed information to the baseboard management controller if the data in the first database is changed.

[0158] In addition, the data in the substrate management controller is transmitted to the editable logic device every 1 hour, and the data of the second database is copied to the first database.

[0159] In some embodiments of the present application, the first index information corresponding to the optical module information is determined according to the preset mapping relationship, the optical module information and the first index information are transmitted to the substrate management controller, and the first database is saved. It is convenient for the substrate management controller to manage the optical module information. When the optical module information is changed, the changed optical module information is synchronized to the substrate management controller, and the optical module information obtained by the substrate management controller is ensured to be accurate and real-time.

[0160] In some embodiments of the present application, a method for managing an optical module is provided, which is applied to a substrate management controller. Figure 8 is a flowchart of a method for managing an optical module according to some embodiments of the present application. As shown in Figure 8, the flow includes the following steps.

[0161] Step S801, obtaining optical module information from a programmable logic device, wherein the optical module information is obtained by the programmable logic device through a communication bus when the optical module is in place and the communication bus between the programmable logic device and the optical module is idle.

[0162] Specifically, the programmable logic device often shares the same communication bus with the HBA card and communicates with the optical module (SFP). In order to avoid data transmission errors, the programmable logic device and the HBA card cannot use the communication bus for communication at the same time. When the HBA card uses the communication bus, the programmable logic device cannot use it. The communication bus is, for example, an IIC bus.

[0163] The programmable logic device can determine whether the communication bus is idle by detecting the level state of the communication bus. For example, if the level state of the communication bus is high for a long time, it means that the communication bus is idle.

[0164] The programmable logic device sends a command to access and read the optical module information stored in the EEPROM of the optical module through the communication bus when it is determined that the optical module is in place and the communication bus between the programmable logic device and the optical module is idle.

[0165] After the programmable logic device obtains the optical module information, it can directly or periodically transmit the optical module information to the substrate management controller through the communication link between the programmable logic device and the substrate management controller. The specific transmission time is determined according to the actual situation. The substrate management controller obtains the optical module information from the programmable logic device.

[0166] Step S802, generating an optical module management strategy according to the optical module information, and executing the optical module management strategy.

[0167] Specifically, the baseboard management controller determines the state of the optical module according to the optical module information after receiving the optical module information, and generates and executes a corresponding optical module management strategy if the optical module state is abnormal, for example: if the temperature of the optical module is too high, the optical module management strategy is to increase the rotation speed of the cooling fan; if a fault code appears in the optical module information, the optical module management strategy is to output alarm information containing the fault code, etc. The optical module management strategy is executed.

[0168] The optical module management method provided by some embodiments of the present application establishes a monitoring channel from the baseboard management controller to the optical module by using the programmable logic device, and the baseboard management controller obtains optical module information from the programmable logic device, so that the optical module information is obtained more timely and comprehensively, more means and information are provided for monitoring and fault diagnosis of the optical module state, and the product competitiveness is enhanced. The problem of lack of timeliness and richness of the optical module information obtained by the baseboard management controller is solved.

[0169] In some embodiments, before obtaining the optical module information from the programmable logic device, the method further comprises:

[0170] determining optical module information requirements;

[0171] generating a first optical module information acquisition instruction according to the optical module information requirements, wherein the first optical module information acquisition instruction is used to instruct the programmable logic device to obtain optical module information corresponding to the optical module information requirements;

[0172] sending the first optical module information acquisition instruction to the programmable logic device.

[0173] Specifically, the baseboard management controller determines the current optical module information requirements, which can be set by the server operation and maintenance personnel. The optical module information requirements are, for example: three kinds of optical module information of voltage, temperature and connection rate of the optical module need to be obtained; two kinds of optical module information of the manufacturer and model of the optical module need to be obtained.

[0174] The baseboard management controller generates a first optical module information acquisition instruction according to the optical module information requirements, sends the first optical module information acquisition instruction to the baseboard management controller through the IIC bus between the baseboard management controller and the programmable logic device, notifies the programmable logic device of the current optical module information requirements, and instructs the programmable logic device to obtain the optical module information corresponding to the optical module information requirements.

[0175] In some embodiments, the method further comprises:

[0176] obtaining the in-place information of the optical module sent by the host bus adapter;

[0177] saving the in-place information, and transmitting the in-place information to the programmable logic device when the programmable logic device queries the in-place information.

[0178] Specifically, the CPLD obtains the in-situ information of the optical module in the following manner: the CPLD reads the in-situ information from the BMC, and the in-situ information in the BMC is obtained from the HBA card. The above manner is shown in FIG. 3. The HBA card obtains the in-situ information of the optical module from the optical module through the IIC bus, and the BMC obtains the in-situ information of the optical module from the HBA card through the PLDM over MCTP out-of-band management manner provided by the HBA card. After receiving the in-situ state query request of the optical module sent by the CPLD, the BMC sends the in-situ state to the CPLD through the IIC bus, wherein in the IIC bus, the CPLD is the master device and the BMC is the slave device. After receiving the in-situ signal of the optical module, the CPLD starts to obtain the information of the optical module.

[0179] In the above manner, the BMC periodically polls the in-situ information of the optical module from the host bus adapter (HBA card) through the PLDM over MCTP out-of-band management manner provided by the HBA card. The BMC saves the in-situ information. The CPLD as the IIC bus master device of the BMC continuously polls the in-situ information of the optical module from the slave BMC. When the CPLD queries the in-situ information, the BMC transmits the in-situ information to the CPLD. In addition, if the CPLD determines that the optical module is not in-situ according to the in-situ information, the CPLD continues to poll the in-situ information from the BMC until the optical module is in-situ.

[0180] In some embodiments of the present application, the BMC obtains the in-situ information of the optical module and transmits the in-situ information to the CPLD, so that the information of the optical module is obtained only when the optical module is in-situ, thereby avoiding wasting communication resources.

[0181] In some embodiments, the optical module management strategy is generated according to the optical module information, comprising:

[0182] determining whether there is a fault code in the optical module information, and if so, generating fault information corresponding to the fault code;

[0183] obtaining a state parameter of the optical module according to the optical module information;

[0184] generating an alarm information if the state parameter is not within a corresponding preset range;

[0185] generating a heat dissipation device scheduling strategy if a temperature in the state parameter is greater than a temperature threshold;

[0186] obtaining the optical module management strategy according to the fault information, the alarm information, and the heat dissipation device scheduling strategy.

[0187] Specifically, the programmable logic device performs logical switching to become an IIC bus master device when the optical module is in place and the communication bus between the optical module is idle, sends a command to obtain optical module information from the optical module, and after obtaining the optical module information, does not parse the optical module information, but directly forwards the optical module information to the BMC through another IIC bus.

[0188] After the BMC receives the optical module information sent by the programmable logic device, the BMC parses the optical module information, stores and updates the parsed information to the component monitoring process of the BMC, realizes monitoring of the optical module, and generates an optical module management strategy according to the optical module information, specifically including:

[0189] The BMC determines whether there is a fault code in the optical module information, and if so, generates fault information corresponding to the fault code.

[0190] The BMC parses the optical module information to obtain the state parameters of the optical module. If the state parameters are not within the corresponding preset range, an alarm information is generated, for example: the normal working voltage of the optical module is 3.3V-5V, the preset range corresponding to the voltage is 3.3V-5V, if the current voltage of the optical module is 8V, which is not within 3.3V-5V, an alarm information is generated to notify that the voltage is too high; the normal working temperature of the optical module is 0℃-60℃, the preset range corresponding to the temperature is 0℃-60℃, if the current temperature of the optical module is 80℃, which is not within 0℃-60℃, an alarm information is generated to notify that the temperature is too high. The BMC can issue an alarm in time when the SFP state is abnormal, so as to facilitate server operation and maintenance;

[0191] In addition, the SFP has high power and large heat dissipation, and the BMC can also take the SFP temperature into the server heat dissipation dimension to perform more reasonable heat dissipation regulation and control. That is, if the temperature in the state parameters is greater than the temperature threshold, a heat dissipation device scheduling strategy is generated, for example: setting the temperature threshold to 60℃, if the temperature is greater than 60℃, the heat dissipation efficiency of the heat dissipation device can be improved, for example: if the heat dissipation device is a air-cooled heat dissipation device, the speed of the heat dissipation fan is increased; if the heat dissipation device is a liquid-cooled heat dissipation device, the flow rate of the cooling liquid is increased, the temperature of the cooling liquid is reduced, etc.

[0192] The BMC integrates the above fault information, alarm information and heat dissipation device scheduling strategy to obtain an optical module management strategy, and the BMC executes the optical module management strategy, for example: outputs the fault information and the alarm information to notify the user to process; executes the heat dissipation device scheduling strategy to increase the speed of the heat dissipation fan or increase the flow rate of the cooling liquid, reduce the temperature of the cooling liquid, etc.

[0193] In some embodiments of the present application, the baseboard management controller generates an optical module management strategy containing fault information, alarm information and heat dissipation device scheduling strategy according to the optical module information. The optical module can work normally, and the stability and reliability of the business are ensured.

[0194] In some embodiments, the obtaining the optical module information from the programmable logic device comprises:

[0195] obtaining the optical module information and corresponding first index information from the programmable logic device;

[0196] storing the optical module information and the first index information into the second database;

[0197] In the case that the second index information and the changed optical module information are obtained from the programmable logic device, updating the optical module information in the second database according to the second index information and the changed optical module information;

[0198] The method further comprises:

[0199] obtaining the optical module information requirement;

[0200] parsing the optical module information requirement to obtain third index information; the third index information comprises a name index and an attribute index of the optical module, or the third index information only comprises the name index of the optical module;

[0201] In the case that the third index information comprises the name index and the attribute index, performing a hierarchical query in the second database according to the name index and the attribute index of the third index information to obtain target optical module information corresponding to the optical module information requirement;

[0202] In the case that the third index information only comprises the name index, taking the optical module information corresponding to the name index of the third index information in the second database as the target optical module information.

[0203] Specifically, as shown in FIG. 7, the second database is created in the baseboard management controller.

[0204] After the baseboard management controller obtains the optical module information and corresponding first index information from the programmable logic device, the baseboard management controller stores the optical module information and the first index information into the second database.

[0205] The baseboard management controller also issues an asynchronous monitoring event to the programmable logic device for monitoring whether the optical module information on the programmable logic device side is changed.

[0206] When the optical module information on the programmable logic device side is changed, the programmable logic device sends the changed optical module information and corresponding second index information to the baseboard management controller. In the case that the second index information and the changed optical module information are obtained from the programmable logic device, the baseboard management controller updates the optical module information in the second database according to the second index information and the changed optical module information.

[0207] When the baseboard management controller manages the optical module, some optical module information is needed, or when the user views some optical module information, the baseboard management controller can query in the first database without obtaining from the programmable logic device, and the query mode can include two kinds: the first query mode, full amount query of information of a single / multiple optical modules: only the name index of the optical module is used for query to obtain all information of the corresponding optical module; the second query mode, query of some information of a certain optical module: name index+attribute index. The steps include:

[0208] The baseboard management controller obtains the optical module information requirement, analyzes the optical module information requirement to obtain third index information; the third index information includes the name index and the attribute index of the optical module, or the third index information only includes the name index of the optical module.

[0209] In the case that the third index information contains the name index and the attribute index, it can be determined that the second query mode, query of some information of a certain optical module, is used, and the target optical module information corresponding to the optical module information requirement is obtained by performing step-by-step query in the second database according to the name index and the attribute index of the third index information, for example: the third index information is 1c, the temperature of SFP1 is queried in the second database; the third index information is 4f, the error code of SFF2 is queried in the second database.

[0210] In the case that the third index information only contains the name index, it can be determined that the first query mode, query of all information of a certain optical module, is used, and the optical module information corresponding to the name index of the third index information in the second database is taken as the target optical module information, for example: the third index information is 1, all attribute information of SFP1 is queried in the second database, including: voltage, connection rate, temperature, manufacturer, model, error code, etc.

[0211] In some embodiments of the present application, the optical module information and the first index information are saved to the second database, so as to facilitate management of the optical module information. The optical module information in the second database is updated according to the change of the optical module information, so as to ensure that the optical module information obtained by the baseboard management controller is accurate and real-time. In addition, when the baseboard management controller needs to obtain the optical module information, the optical module information is directly queried from the second database, so as to improve the optical module information obtaining efficiency.

[0212] Some embodiments of the present application provide an optical module management system, which includes: a baseboard management controller, a programmable logic device, and a preset number of optical modules.

[0213] The programmable logic device and the optical module are connected through a communication bus, and the baseboard management controller is connected with the programmable logic device.

The monitoring channel from the baseboard management controller to the optical module is established by using the programmable logic device, so that the acquisition of the optical module information is more timely and comprehensive, more means and information are provided for the monitoring and fault diagnosis of the optical module state, and the product competitiveness is enhanced. The problem of lack of timeliness and richness of the optical module information acquired by the baseboard management controller is solved.
