The external functional devices can be interconnected with the main board through connectors and adapter boards, so as to realize signal transfer and transmission through the connectors and adapter boards. However, when the main board faces multiple external functional devices, it is difficult for the adapter board to adapt to the management and control of multiple external functional devices. Summary of the Invention

[0003] In view of the above problems, the present application provides a control system and a control method.

[0004] According to a first aspect of the present application, there is provided a control system, including: an adapter expansion board for electrically connecting to a main board and at least one adapter module via a cable, so that data signals are transmitted between the main board and at least one adapter module through the cable; a controller disposed on the adapter expansion board for real-time monitoring of the hot-plug state of at least one adapter module, receiving status signals sent by at least one adapter module electrically connected to the controller, and determining a target management mode of at least one adapter module according to the at least one status signal to manage at least one adapter module; a connector disposed on the adapter expansion board, including a plurality of main board connectors and a plurality of adapter connectors, the plurality of main board connectors being used for electrically connecting to the main board through a cable, and the plurality of adapter connectors being used for electrically connecting to at least one adapter module through a plurality of adapter devices.

The adapter expansion board is electrically connected to the main board and at least one adapter module via a cable. Both the controller and the connector may be disposed on the adapter expansion board. The connector on the adapter expansion board may include a main board connector electrically connected to the main board and an adapter connector electrically connected to the adapter module. During the normal operation of the server, in response to the hot plugging and unplugging of the adapter module, the controller on the adapter expansion board monitors the hot plugging and unplugging state of the adapter module in real time, and updates the at least one adapter module currently electrically connected to the main board according to the monitoring result, realizing real-time monitoring of the hot-pluggable adapter module while supporting the hot plugging and unplugging of the adapter module during the operation of the server, so as to facilitate the system management of the at least one adapter module by the processor on the main board.

Further, the controller on the adapter expansion board is used to confirm the status and management mode of each adapter module, so that the processor on the main board does not need to perform logical confirmation on the management and connection of the adapter module, improving resource utilization and processing efficiency.

[0022] As the amount of data processed by the server increases, existing servers usually, on the basis of a processor, are equipped with external functional devices including computing units such as graphics processors to jointly calculate and process a large amount of data. The external functional device can be interconnected with the motherboard through a connector and an adapter board, so as to realize signal transfer and transmission through the connector and the adapter board. However, when the motherboard faces multiple external functional devices, it is difficult for the adapter board to adapt to the management and control of multiple external functional devices.

[0023] An embodiment of the present application provides a control system, including: an adapter expansion board for electrically connecting to the motherboard and at least one adapter module via a cable, so that data signals are transmitted between the motherboard and at least one adapter module through the cable; a controller disposed on the adapter expansion board for real-time monitoring of the hot-swap state of at least one adapter module, receiving status signals sent by at least one adapter module electrically connected to the controller, and determining a target management mode of at least one adapter module according to the at least one status signal to manage at least one adapter module; a connector disposed on the adapter expansion board, including a plurality of motherboard connectors and a plurality of adapter connectors, the plurality of motherboard connectors being used for electrically connecting to the motherboard through a cable, and the plurality of adapter connectors being used for electrically connecting to at least one adapter module through a plurality of adapter devices.

[0024] According to an embodiment of the present application, the control system may include an adapter expansion board, a controller, and a connector.

[0025] According to an embodiment of the present application, the adapter expansion board is electrically connected to the motherboard and at least one adapter module via a cable to transmit data signals between the motherboard and at least one adapter module through the cable.

[0026] The cable may include cables for transmitting data signals such as high-speed signal cables, low-speed signal cables, power cables, sideband signal cables, etc. Control and processing units such as a processor (CPU, Central Processing Unit) and a baseboard management controller (BMC) may be provided on the motherboard, and the adapter module may be characterized as an external functional device including a computing unit such as a graphics processor.

[0027] Through the adapter expansion board, multiple adapter modules including functional processors can be electrically connected to the head of the server, so that the processor and the baseboard management controller can be matched with one or more adapter modules according to requirements for efficient management and operation.

[0028] According to an embodiment of the present application, a controller is provided on an adapter expansion board, and is used to monitor the hot-swap status of at least one adapter module, receive a status signal from at least one adapter module electrically connected to the controller, and determine a target management mode of at least one adapter module based on at least one status signal.

[0029] By providing a controller (CPLD, Complex Programmable Logic Device) on the adapter expansion board, the adapter expansion board can be equipped with the corresponding computing and logical processing capabilities, thereby enabling real-time monitoring of the hot-swap status of the adapter module, thereby supporting hot-swapping of the adapter module during normal server operation. Furthermore, by monitoring the hot-swap status of the adapter module in real time, it is possible to determine which one or more adapter modules currently form a data path and electrical connection with the mainboard for communication, and then determine the management mode of one or more adapter modules, and establish a matching target management mode based on status signals or current computing needs.

[0030] According to an embodiment of the present application, the connector is arranged on the adapter expansion board, including multiple mainboard connectors and multiple adapter connectors. The mainboard connector is electrically connected to the mainboard through a cable, and the multiple adapter connectors are electrically connected to at least one adapter module through multiple adapter devices.

[0031] The adapter expansion board is equipped with multiple motherboard connectors for electrically connecting to the high-speed connectors and low-speed connectors on the mainboard, and adapter connectors for electrically connecting to the adapter module BOX. Through connectors and cables with various functional purposes, the various modules in the server are electrically connected together to achieve data communication.

[0032] According to an embodiment of the present application, the control system may include an adapter expansion board, a controller, and a connector. The adapter expansion board is electrically connected to the mainboard and at least one adapter module via a cable. The controller and the connector may be arranged on the adapter expansion board. The connector on the adapter expansion board may include a mainboard connector electrically connected to the mainboard and an adapter connector electrically connected to the adapter module. During normal operation of the server, in response to hot plugging of the adapter module, the controller on the adapter expansion board monitors the hot plugging status of the adapter module in real time, and updates the at least one adapter module currently electrically connected to the mainboard in real time based on the monitoring result. This achieves real-time monitoring of the hot plugged adapter module while supporting the hot plugging of the adapter module during operation of the server, thereby facilitating system management of the at least one adapter module by the processor on the mainboard.

[0033] According to an embodiment of the present application, after monitoring and obtaining the hot-swappable status of the adapter module, a status signal from at least one adapter module can be received based on the number of adapter modules electrically connected to the mainboard or a preset requirement, and the at least one currently connected adapter module can be confirmed based on the received status signal, so that the current target management mode for at least one adapter module can be determined when the status signals are all received normally or the information is transmitted normally, thereby realizing online real-time management of one or more adapter modules based on the hot-swappable state of the adapter module, and determining the current target management mode and flexible configuration of the management mode based on the status signal of each adapter module itself and the logical judgment within the controller, so that the processor on the server head can be matched with any number of adapter modules. Furthermore, the status and management mode of each adapter module are confirmed by the controller on the adapter expansion board, thereby eliminating the need for the processor on the mainboard to perform logical confirmation on the management and connection of the adapter module, thereby improving resource utilization and processing efficiency.

[0034] Figure 1 A schematic diagram of a control system according to an embodiment of the present application is shown.

[0035] like Figure 1 As shown, the control system may include an adapter expansion board 101, a controller 102 and a connector. The adapter expansion board 101 is electrically connected to a mainboard 104 and multiple adapter modules 105 via a cable 103. The controller 102 and the connector may both be set on the adapter expansion board 101. The connector on the adapter expansion board 101 may include a mainboard connector 106 electrically connected to the mainboard 104 and an adapter connector 107 electrically connected to the adapter module 105.

[0036] According to an embodiment of the present application, the status signal may include a presence signal and a power-on completion signal.

[0037] According to an embodiment of the present application, the controller may further be configured to: determine at least one adapter module electrically connected to the adapter expansion board based on a hot-swap state of the at least one adapter module.

[0038] The adapter expansion board can be electrically connected to multiple adapter modules. As the server runs, the adapter module can be hot-swapped and unplugged according to demand, so it is necessary to confirm the number of adapter modules currently electrically connected to the adapter expansion board in real time, and then determine the target management mode based on the number of adapter modules electrically connected to the adapter expansion board.

[0039] According to an embodiment of the present application, in response to receiving a presence signal sent by at least one adapter module, a target management mode of the at least one adapter module is determined, and a power-on instruction is sent to the at least one adapter module.

[0040] When determining the number of adapter modules electrically connected to the adapter expansion board, the controller can send a presence detection command to these adapter modules. After receiving the presence detection command, the adapter module can send a presence signal to the controller.

[0041] When the controller receives the presence signal sent by the adapter module, it confirms that the adapter module is present and then issues a power-on command to it. When the controller does not receive the presence signal sent by the adapter module, it confirms that the adapter module is not present, and thus does not issue a power-on command to the adapter module.

[0042] According to an embodiment of the present application, in response to receiving a power-on completion signal sent by at least one adapter module, the target management mode, at least one presence signal, and at least one power-on completion signal are sent to the processor of the main board to implement data communication between the processor and at least one adapter module.

[0043] The adapter module powers on the system according to the received power-on command. After the power-on is completed, it generates a power-on completion signal and sends it to the controller. The controller can determine the current target management mode according to the number of received power-on completion signals. For example, the number of adapter modules currently electrically connected to the adapter expansion board is 3. The controller obtains the presence signals and power-on completion signals of the first and third adapter modules, but does not obtain the presence signal of the second adapter module, thereby determining that the current target management mode is the one-to-two mode. Or, the controller obtains the presence signals and power-on completion signals of the first and third adapter modules, but does not obtain the power-on completion signal of the second adapter module, and thus can also determine that the current target management mode is the one-to-two mode. That is, without other preset requirements, the controller can automatically determine the target management mode according to the number of currently connected adapter modules and the configuration completion degree of the status signals.

[0044] According to an embodiment of the present application, the controller can first determine at least one adapter module currently electrically connected to the main board and the adapter expansion board according to the real-time monitored hot-plug state, so as to avoid the situation where the processor and the controller do not update the adapter module in time or the adapter module is loosely plugged or unplugged after the adapter module is hot-plugged or hot-unplugged, facilitating accurate management of the adapter module. Then it sends a presence detection command to at least one adapter module. After receiving the presence signal of the adapter module, it issues a power-on command to it. After receiving the power-on completion signal of the adapter module, it determines the current target management mode and reports the corresponding information to the processor of the main board, so that the processor can back up and monitor the current system mode, realizing the determination of the target management mode through the transmission and verification of communication data signals.

[0045] According to an embodiment of the present application, the controller can also be used to: when multiple adapter modules are electrically connected to the adapter expansion board, determine target management information based on the system resource policy, wherein the target management information includes the target management mode, the number information of the adapter modules to be enabled, and the identification information of the adapter modules to be enabled.

[0046] When multiple adapter modules are electrically connected to the adapter expansion board, a target management mode corresponding to some, one, or all adapter modules may be selected from the multiple adapter modules according to the current system resource policy.

[0047] System resource policies can be characterized as policy information containing the number and identifiers of the adapter modules to be activated, generated based on a comprehensive multi-dimensional set of factors, including the current required resource quantity, resource concentration, server capacity, power supply power, and adapter module processing speed. For example, when the number of resources is low, a smaller number of adapter modules can be selectively activated, while when the number of resources is high, a larger number of adapter modules can be selectively activated.

[0048] Generally speaking, the information on the number of adapter modules to be enabled is determined to correspond to the target management mode. For example, when it is determined that there are four adapter modules to be enabled, the target management mode is confirmed to be a one-to-four mode.

[0049] According to an embodiment of the present application, at least one to-be-enabled switching module is determined from a plurality of switching modules based on quantity information and identification information, and a get-in-place instruction is sent to the at least one to-be-enabled switching module.

[0050] The controller determines the adapter module with corresponding identification information from multiple adapter modules based on the identification information in the target management information. For example, when two adapter modules need to be called, and the first adapter module and the third adapter module need to be called, the controller sends the get in place instruction to the adapter module with the identification of sequence one and the adapter module with the identification of sequence three according to the sequential identification of each adapter module.

[0051] Since the power consumption, resource occupancy, and resource processing speed of different adapter modules may be different, when the adapter module is hot-plugged, the storage module on the adapter expansion board can store the attribute information of each hot-plugged adapter module, and based on the attribute information, confirm the selection of the current optimal adapter module.

[0052] According to an embodiment of the present application, in response to receiving a presence signal sent by at least one adapter module to be enabled, a power-on instruction is generated and sent to the at least one adapter module to be enabled.

[0053] When the to-be-enabled transfer module receives the in-position instruction, it sends an in-position signal to the controller. After receiving the in-position signal sent by the to-be-enabled transfer module, the controller sends a power-on instruction to it.

[0054] When the controller does not receive the in-position signal sent by the to-be-enabled transfer module, it can send the in-position instruction to the to-be-enabled transfer module again. If there is still no response after the in-position instruction is sent twice, it can report the abnormal situation of the to-be-enabled transfer module to the processor, determine a new to-be-enabled transfer module that can replace the abnormal transfer module from multiple transfer modules other than the abnormal transfer module, and update the target management information.

[0055] According to an embodiment of the present application, in response to receiving the power-on completion signal sent by at least one to-be-enabled transfer module, determine the target management mode, and send the target management information, at least one in-position signal, and at least one power-on completion signal to the processor of the main board.

[0056] When the in-position signal and the power-on completion signal of the to-be-enabled transfer module corresponding to both the quantity information and the identification information in the target management information are received, determine the intermediate management mode at this time, and verify it with the target management mode in the target management information. When the intermediate management mode is consistent with the target management mode, determine that the target management mode is completed. When the intermediate management mode is inconsistent with the target management mode, perform verification according to the received in-position signal, power-on completion signal, identification information, and quantity information. If there is no abnormality in the verification, it can be temporarily operated in the current intermediate management mode, and at the same time report the abnormal information to the processor of the main board and the baseboard management controller for secondary verification. It can also regenerate the target management information based on the system resource policy, and then re-call the transfer module. If the call is consistent this time, determine that the target management mode is completed. If the call is still inconsistent this time, suspend the call and send the abnormal information to the processor and the baseboard management controller.

[0057] According to an embodiment of the present application, when there are multiple adapter modules electrically connected to the adapter expansion board, the target management information can be determined first according to the system resource policy, and then the corresponding adapter module can be enabled based on the information in the target management mode. Therefore, the corresponding multiple adapter modules can be started more flexibly according to the resource consumption rate and the attribute information of the adapter module itself. In implementing the corresponding target management mode, the utilization rate of the adapter module and the work efficiency of the server are improved. Since the generation of target management information and the determination of the target management mode are both independently confirmed by the controller on the adapter expansion board based on logical judgment, in the absence of abnormal adapter modules or abnormal information, the information can be directly reported to the processor after confirming the target management mode, so that the processor can perform backup and resource allocation, thereby eliminating the need for the processor or baseboard management controller to enable the adapter module, thereby improving work efficiency.

[0058] According to an embodiment of the present application, the controller can also be used to: upon receiving a power-on abnormality signal issued by at least one to-be-enabled adapter module, send a pause instruction to the abnormal adapter module, and send a get-in-place instruction to at least one to-be-enabled adapter module other than the abnormal adapter module based on quantity information.

[0059] The power-on exception signal may include an abnormal power-on completion signal or no signal. When a power-on exception signal is received, the switching module to be enabled that sends the power-on exception signal is marked as abnormal, and its status can be changed to an abnormal switching module.

[0060] According to an embodiment of the present application, the target management mode is determined when a presence signal and a power-on completion signal are received from at least one switching module to be enabled except for the abnormal switching module.

[0061] When the normal adapter module to be enabled replaces the abnormal adapter module to receive and obtain the in-place instruction, feedback the in-place signal, receive the power-on instruction, and feedback the power-on completion signal, the target management mode of the activated adapter module at this time can be confirmed in the same way as above.

[0062] According to an embodiment of the present application, the identification information in the target management information is updated to obtain updated target management information, and the updated target management information, at least one in-place signal and at least one power-on completion signal are sent to the processor of the mainboard.

[0063] The identification information of the abnormal switching module in the target management information is updated according to the identification information of the normal switching module to be enabled for replacing the abnormal switching module, so that the processor can receive the current and accurate management information of the switching module.

[0064] According to an embodiment of the present application, in the case where any to-be-enabled transfer module has a power-on anomaly, the start of the abnormal transfer module can be suspended, and a to-be-enabled transfer module for replacing the abnormal transfer module can be selected and called from the remaining to-be-enabled transfer modules. After the to-be-started transfer module normally sends an in-position signal and a power-on completion signal to the controller, the target management information is updated, achieving flexible management and control when the transfer module is abnormal and ensuring accurate target management information is fed back to the processor to facilitate data communication between the processor and the running transfer module.

[0065] Figure 2 FIG. shows a schematic diagram of a control system according to another embodiment of the present application.

[0066] As Figure 2 shown, the control system may include a transfer expansion board 101, a controller 102, and a connector. The main board includes a processor 201 and a baseboard management controller 202. The main board 104, the first transfer module, the second transfer module, the third transfer module, and the fourth transfer module 206 are electrically connected to the transfer expansion board 101 through cables. In the case of electrically connecting four to-be-enabled transfer modules to the transfer expansion board 101, the controller determines the target management information according to the current system resource policy. The target management information includes selecting two to-be-enabled transfer modules from the four transfer modules and calling the first to-be-enabled transfer module 203 and the second to-be-enabled transfer module 204, and the target management mode is a one-drag-two mode. Then, according to the sequence identifier of each transfer module, an in-position acquisition instruction is sent to the first to-be-enabled transfer module 203 and the second to-be-enabled transfer module 204. In the case of receiving the in-position signals of the first to-be-enabled transfer module 203 and the second to-be-enabled transfer module 204, a power-on instruction is sent to them. The controller receives the power-on completion signal of the first to-be-enabled transfer module 203 and the power-on anomaly signal of the second to-be-enabled transfer module 204, thereby marking the second to-be-enabled transfer module 204 as abnormal, that is, the second to-be-enabled transfer module 204 (abnormal), and sending a suspension instruction to it. An in-position acquisition instruction is sent to the third to-be-enabled transfer module 205. In the case of receiving the in-position signal sent by the third to-be-enabled transfer module 205, a power-on instruction is sent to the third to-be-enabled transfer module 205. The controller receives the power-on completion instruction sent by the third to-be-enabled transfer module 205, and then updates the original target management mode according to the identification information of the third to-be-enabled transfer module 205 to obtain an updated target management mode, and sends it to the processor 201 and the baseboard management controller 202.

[0067] According to an embodiment of the present application, the controller can also be used to: send a self-detection test instruction to the abnormal transfer module to enable the abnormal transfer module to perform a self-check power-on test.

[0068] While invoking a new transfer module to be enabled, a self-detection test instruction can be sent to the abnormal transfer module. If the self-detection of the abnormal transfer module is successful, the work efficiency can be improved.

[0069] According to an embodiment of the present application, in the case of receiving a self-detection power-on completion signal from the abnormal transfer module, the abnormal transfer module is reset, and the abnormal transfer module is updated to a transfer module with a normal state.

[0070] In the case where the abnormal transfer module successfully sends a self-detection power-on completion signal to the controller, it can be proved that the self-detection test of the abnormal transfer module is successful at this time. Thus, it is possible to continue waiting to invoke this transfer module without hot-plugging for physical repair. At the same time, the power-on abnormal information of this transfer module can also be sent to the processor to facilitate hot-plugging it for maintenance when this transfer module is not in use.

[0071] According to an embodiment of the present application, the controller can also be used to: in the case of receiving a self-detection power-on abnormal signal from the abnormal transfer module, send a hot-plug self-detection instruction to the abnormal transfer module, and send hot-plug control information to the processor and the baseboard management controller of the main board.

[0072] In the case where the abnormal transfer module still cannot send a normal self-detection power-on completion signal to the controller, a hot-plug self-detection instruction is sent to the abnormal transfer module, that is, it is notified to perform hot-plugging and hot-inserting processing on this abnormal transfer module, so as to detect it.

[0073] Before hot-plugging the abnormal transfer module, control information indicating that the abnormal transfer module needs to be hot-plugged needs to be sent to the processor and the baseboard management controller, so that the processor and the baseboard management controller can control an independent power-off operation for it.

[0074] According to an embodiment of the present application, in response to the hot-insertion of the abnormal transfer module, the hot-plug state of the abnormal transfer module is monitored and confirmed. In the case where the hot-plug state of the abnormal transfer module is normal insertion, a self-detection test instruction is sent to the abnormal transfer module.

[0075] In the case where the abnormal transfer module can be normally inserted, it can be re-self-detected after hot-plugging.

[0076] According to an embodiment of the present application, in the case of receiving a self-detection power-on completion signal from the abnormal transfer module, the abnormal transfer module is reset, and the abnormal transfer module is updated to a transfer module with a normal state.

[0077] When the hot plug state of the exception transfer module is an insertion exception or it is still unable to send a self - test power - on completion signal to the controller after normal insertion, an alarm message indicating that the exception transfer module is damaged is notified to the processor and the baseboard management controller, so as to facilitate physical maintenance of the exception transfer module.

[0078] According to an embodiment of the present application, by issuing a self - test instruction to the exception transfer module, and based on the self - test power - on test result of the exception transfer module, it is determined whether the exception transfer module can autonomously resume normal power - on. When the exception transfer module cannot autonomously resume power - on, a self - test instruction for hot plug is sent to the exception transfer module. After the exception transfer module undergoes operations of hot removal and hot insertion, it performs a re - self - test verification. When the self - test verification after hot plug is successful, a reset process is performed on the exception transfer module, and its exception status is changed, realizing the processing of self - test maintenance for the exception transfer module. When the self - test maintenance is successful, there is no need to perform physical maintenance on it, improving the high - level management efficiency of the controller for the transfer module.

[0079] According to an embodiment of the present application, the controller can also be used to: when determining target management information based on the system resource policy, send a transfer module query instruction to the processor according to the identification information.

[0080] Since after each confirmation of the target management mode, the target management information is reported to the processor so that the processor can obtain the target management information. Therefore, when currently determining the target management information, the historical startup record of the transfer module corresponding to the identification information can be obtained from the processor according to the identification information.

[0081] According to an embodiment of the present application, based on the received transfer module query information from the processor, the previous enabling information of at least one to - be - enabled transfer module is determined.

[0082] The previous enabling information can be characterized as the previous historical startup record of the transfer module.

[0083] According to an embodiment of the present application, when the previous enabling information indicates an abnormal enabling, a get - in - place instruction and a power - on instruction are generated and sent to at least one to - be - enabled transfer module.

[0084] When the previous enabling information of a certain to - be - enabled transfer module indicates an abnormal enabling, a secondary verification by the processor and the baseboard management controller can be performed on the certain to - be - enabled transfer module during the current startup process. When the previous enabling information of a certain to - be - enabled transfer module indicates a normal enabling, there is no need for secondary verification by the processor and the baseboard management controller on the main board.

[0085] According to an embodiment of the present application, in response to receiving the presence signal and the power-on completion signal from at least one transfer module to be enabled, the presence signal, the power-on completion signal, and the identification information are sent to the baseboard management controller, so that the baseboard management controller performs an enablement confirmation.

[0086] During the current startup process, for a transfer module to be enabled whose previous enablement information indicates an enablement anomaly, a presence instruction is normally sent to obtain its presence signal, and then a power-on instruction is sent to obtain its power-on completion signal.

[0087] According to an embodiment of the present application, in the case of receiving an enablement confirmation instruction from the baseboard management controller, a target management mode is determined, and the target management information, at least one presence signal, and at least one power-on completion signal are sent to the processor of the main board.

[0088] In the case of receiving an enablement anomaly instruction from the baseboard management controller, the transfer module is not started, and any one of the other transfer modules to be enabled is selected for enabling.

[0089] According to an embodiment of the present application, the controller can also be used for: in the case of receiving a power-on anomaly signal from at least one transfer module to be enabled, the presence signal, the power-on anomaly signal, and the identification information are sent to the baseboard management controller, so that the baseboard management controller performs an enablement confirmation.

[0090] According to an embodiment of the present application, in response to receiving an enablement confirmation instruction from the baseboard management controller, a target management mode is determined, the target management information, at least one presence signal, and at least one power-on completion signal are sent to the processor of the main board, and controller anomaly judgment information is generated and sent to the processor and the baseboard management controller to perform a self-check process on the controller.

[0091] The baseboard management controller can be set to have a higher processing decision priority compared to the controller on the transfer expansion board. For a transfer module that had the aforementioned abnormal enablement but is now in a normal state, when the controller verification fails, the baseboard management controller can perform the final verification management on whether to start it.

[0092] According to an embodiment of the present application, when starting the to-be-enabled transfer module according to the current target management information, the historical start information of the to-be-enabled transfer module can be obtained and verified. When the last start record of the to-be-enabled transfer module is an abnormal start, but the current state is a normal state, the baseboard management controller with a higher-priority control decision on the main board is called to double-verify the received in-position signal, power-on completion signal, and power-on abnormal signal, and the instruction issued by the baseboard management controller can be used as the final start instruction to start the to-be-enabled transfer module. Thus, before each start of the to-be-started transfer module, it can be double-verified according to the historical record, and with the main board as the core control center, when an abnormality occurs, the instruction information of the baseboard management controller or the processor of the main board is used as the execution instruction to ensure the scheduled start and normal operation of the transfer module, improving the management efficiency.

[0093] The controller can also, when the current target management mode is running normally, change the running target management mode according to the change in the resource distribution within the server. When it is necessary to change the currently running target management mode, new target management information can be generated first based on the change in the resource distribution, and the new target management information and the current target management information are compared. For the transfer modules that are running and have the same identification information, their running status is maintained, and for the transfer modules with different identification information, instructions to pause running and reset are separately sent to some of the currently running transfer modules. After waiting for the reset to complete, start instructions are sent to some of the transfer modules in the new target management information, thereby improving the flexibility of transfer module invocation and management.

[0094] According to an embodiment of the present application, the controller can also be used to: in response to receiving a transfer module hot-insertion signal from the baseboard management controller, generate a first power monitoring signal and send it to the processor.

[0095] The controller can support the hot-plug behavior of the transfer module during the normal operation of the server. After detecting the insertion of the CDFP (C-Form Factor Pluggable) cable of the transfer module, the baseboard management controller can send the hot-insertion key waveform in the simulated Hotplug (hot-plug) key waveform, that is, the transfer module hot-insertion signal, to the controller, so that the controller generates a first power monitoring signal and reports it to the processor.

[0096] According to an embodiment of the present application, according to the received module status acquisition instruction from the processor, an in-position acquisition instruction and a power-on instruction are generated and sent to the to-be-inserted transfer module.

[0097] When the processor receives the first power monitoring signal, it sends a module status collection instruction to the controller. In response to the module status collection instruction, the controller reads the presence status of the adapter module to be inserted and sends it to the processor. After receiving the presence status, the processor sends a power-on instruction to the adapter module through the controller.

[0098] According to an embodiment of the present application, when receiving the presence signal and the power-on completion signal from the adapter module to be inserted, perform a reset process on the adapter module to be inserted, and update the adapter module to be inserted as an adapter module.

[0099] When receiving the presence signal and the power-on completion signal from the adapter module to be inserted, the controller sends the presence signal and the power-on completion signal to the processor. The processor sends a reset instruction to the adapter module to be inserted through the controller to make it perform a reset process and update its status.

[0100] According to an embodiment of the present application, the controller can also be used to: in response to receiving a hot removal signal of the adapter module from the baseboard management controller, generate a second power monitoring signal and send it to the processor.

[0101] Before the CDFP (C-Form Factor Pluggable) cable of the adapter module is ready to be removed, the baseboard management controller can send a hot removal key waveform in the simulated Hotplug key waveform, that is, a hot removal signal of the adapter module, to the controller, so that the controller generates a second power monitoring signal and reports it to the processor.

[0102] According to an embodiment of the present application, generate and send a presence collection instruction and a power-off instruction to the adapter module according to the received module status collection instruction from the processor.

[0103] When the processor receives the second power monitoring signal, it sends a module status collection instruction to the controller. In response to the module status collection instruction, the controller reads the presence status of the adapter module and sends it to the processor. After receiving the presence status, the processor sends a power-off instruction to the adapter module through the controller.

[0104] According to an embodiment of the present application, when receiving the lower position signal and the power-off completion signal from the adapter module to be inserted, update the adapter module to the adapter module to be inserted.

[0105] When receiving the presence signal and the power-off completion signal from the adapter module to be inserted, the controller sends the presence signal and the power-off completion signal to the processor, so that the adapter module can perform a hot removal process and update its status.

[0106] According to an embodiment of the present application, the controller on the adapter expansion board can support the hot pluggable operation of the adapter module during the operation of the server. When performing a hot insertion operation, the baseboard management controller issues a general command. The processor and the controller respond to the general command issued by the baseboard management controller, retrieve the presence signal of the presence state of the adapter module currently in a to-be-inserted state, and then control its power-on to obtain a corresponding power-on completion signal and feedback it to the processor. After receiving the presence signal and the power-on completion signal, the processor resets the adapter module in the to-be-inserted state and changes its state through the controller. When performing a hot insertion operation, similarly, the baseboard management controller issues a general command, the processor and the controller respond to the general command issued by the baseboard management controller, retrieve the presence signal of the presence state of the adapter module currently in a to-be-inserted state, and then control its power-off to obtain a corresponding power-off completion signal and feedback it to the processor. After receiving the presence signal and the power-off completion signal, the processor can hot-remove the adapter module and change its state, realizing the state configuration of power-on and power-off after the hot insertion of the adapter module and before the hot removal, so that when the adapter module needs to be replaced, it can be replaced without powering off.
