Description

Technical Field

[0001] This application relates to the field of electronic systems, and in particular to a method, apparatus and readable storage medium for controlling a node. Background Technology

[0002] With the gradual advancement of electronic technology, node management in servers has become a hot topic. Currently, the management node in commonly used servers supports a maximum of 239 controlled nodes. When the maximum number of controlled nodes is supported, the download time of the management node to the controlled nodes is too long. Generally speaking, the download of a node takes about 5 minutes.

[0003] Figure 1 Here is a schematic diagram of an existing node control structure, such as Figure 1 As shown, MN is the management node and CN is the controlled node. During the current node download process, within one cycle, the MN node can only send a request or response to the designated CN node once asynchronously. Therefore, two complete cycles are needed for the MN node to complete one data transmission with the designated CN node. During this process, the controlled node will disconnect from the management network and then rejoin, causing interference to the entire system. For example, a management node supports 239 controlled nodes, the cycle between the management node and controlled nodes is 25ms, and each controlled node has 16 configuration data entries. Since restarting and rejoining the network requires an additional 8 communications, the configuration process takes approximately 287 seconds. During the entire node download process, all nodes are disconnected from the system, resulting in approximately 5 minutes of server downtime, causing service delays or even failures.

[0004] Given the above-mentioned technologies, finding a more stable control node is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, and readable storage medium for controlling nodes, so as to solve the problem that existing solutions cause all nodes to disconnect from the system during the entire node download process, resulting in the server being unable to work normally for about 5 minutes, which leads to the slowdown or even failure of business operations on the server.

[0006] To address the aforementioned technical problems, this application provides a method for controlling a node, applied to a management node, comprising:

[0007] Set the control cycle period to an arbitrary adjustable time and send the configuration information to each controlled node via the PReq extended message;

[0008] Detect whether each of the controlled nodes has received the PReq extended message;

[0009] If not, return to the step of sending configuration information to each controlled node via PReq extended messages;

[0010] If so, the control cycle time is set to a preset cycle time, the asynchronous phase is entered, and a configuration update instruction is sent so that the controlled node can update its configuration according to the configuration information after receiving the configuration update instruction.

[0011] Preferably, detecting whether each of the controlled nodes has received the PReq extended message includes:

[0012] Enter the synchronization phase of the next cycle and receive the Pres messages sent by each of the controlled nodes;

[0013] The detection method checks whether each controlled node has received the PReq extended message based on the Pres message.

[0014] Preferably, after setting the control cycle period time to an arbitrary adjustable value, the method further includes:

[0015] The periodic time modification information is broadcast to each of the controlled nodes so that the controlled nodes can disable the timeout protection state.

[0016] Preferably, after entering the asynchronous phase and sending the configuration update instruction, the method further includes:

[0017] Read the configuration parameters of the controlled node, and determine whether the controlled node has been configured based on the configuration parameters;

[0018] If not, an alert will be issued to prompt the user to make configuration changes.

[0019] To address the aforementioned problems, this application also provides a method for controlling a node, applied to a controlled node, comprising:

[0020] The system receives the PREQ extended message sent by the management node and parses the configuration information according to the PREQ extended message. The management node is a node whose control cycle time is arbitrarily adjustable.

[0021] After receiving the configuration information, a feedback message is sent to the management node;

[0022] Receive the configuration update instruction sent by the management node, and perform configuration update according to the instruction and the configuration information.

[0023] Preferably, after receiving the PReq extended message sent by the management node and parsing the configuration information based on the PReq extended message, the method further includes:

[0024] The configuration information is cached, and the integrity of the configuration information in the cache space is checked.

[0025] If so, proceed to the step of sending feedback information to the management node after receiving the configuration information.

[0026] To address the aforementioned problems, this application also provides a control node apparatus, applied to a management node, comprising:

[0027] The configuration module is used to set the control cycle time to an arbitrary adjustable value and send configuration information to each controlled node through PReq extended messages.

[0028] The detection module is used to detect whether each of the controlled nodes has received the PReq extended message. If so, it returns to the setting module; otherwise, it enters the sending module.

[0029] The sending module is used to set the control cycle time to a preset cycle time, enter the asynchronous phase, and send a configuration update instruction so that the controlled node can update its configuration according to the configuration information after receiving the configuration update instruction.

[0030] To address the aforementioned problems, this application also provides an apparatus for controlling a node, comprising:

[0031] The receiving module is used to receive the PREQ extended message sent by the management node, and parse the configuration information according to the PREQ extended message. The management node is a node whose control cycle time is arbitrarily adjustable.

[0032] The feedback module is used to send feedback information to the management node after receiving the configuration information;

[0033] The update module is used to receive the configuration update command sent by the management node and perform configuration update according to the command and the configuration information.

[0036] To address the aforementioned problems, this application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the control node method described above.

[0037] The control node method provided in this application is applied to the management node. After the management node exits the periodic restriction, it sends information to the controlled node according to the PReq extended message. After receiving the configuration information, the controlled node resumes periodic operation. In the asynchronous phase of the next period, the controlled node performs the corresponding configuration update. Compared with the previous method of sending and receiving feedback through two asynchronous phases, the technology used in this solution does not require the controlled node to be disconnected from the management node. It only achieves online updates of the controlled node by modifying the period and data transmission method, and transmits data through messages. Then, in the asynchronous phase, the management node does not need to perform configuration updates again, but only needs to wait for the corresponding controlled node to update, which greatly improves the working efficiency of the server and ensures the stability of the server operation.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0046] The core of this application is to provide a method, apparatus, and readable storage medium for controlling nodes, so as to solve the problem that all nodes are disconnected from the system during the entire node download process, resulting in the server being unable to work normally for about 5 minutes, which leads to the slowdown or even failure of business operations on the server.

[0047] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Figure 2 A flowchart of a method for controlling a node provided in an embodiment of this application is shown below. Figure 2 As shown, the method includes:

[0049] S10: Set the control cycle period time to an arbitrary adjustable value, and send the configuration information to each controlled node through the PReq extended message;

[0050] It is understandable that, based on the above... Figure 1 In the data transmission method, existing data transmission is generally divided into three stages: idle stage, synchronous stage, and asynchronous stage. The corresponding control cycle time can be obtained in the three stages. In this embodiment, the cycle time is set to be arbitrarily adjustable, while the feedback of the controlled node to the received information also needs to be considered. This will not be elaborated in this embodiment. The arbitrarily adjustable time mentioned in this embodiment refers to the specific cycle length of the management node. In this embodiment, the specific cycle state is manually switched by the user or set to switch the cycle after all controlled nodes receive the extended message. Therefore, the time of each complete cycle is not fixed. Here, an arbitrarily adjustable cycle time is adopted.

[0051] S11: Check whether each controlled node has received the PReq extended message. If not, return to S10; if yes, proceed to S12.

[0052] It should be noted that a message is a data unit exchanged and transmitted in a network, that is, a data block that a station sends at one time. A message contains complete data information to be sent, and its length varies greatly, being unlimited and variable. In this embodiment, there are no limitations on the specific type of message or its corresponding data unit format, etc. It should be noted that, for extended messages, the content of the core data is not specifically limited in this embodiment.

[0053] S12: Set the control cycle time to the preset cycle time, enter the asynchronous phase, and send the configuration update command.

[0054] The above steps facilitate the controlled node's configuration update based on the configuration information upon receiving the configuration update command. It should be noted that in this embodiment, the specific time period of the preset period is not limited; that is, the specific method for setting the preset period, the content of the preset period, etc., are not specifically limited.

[0055] The control node method provided in this embodiment is applied to the management node. After the management node exits the periodic restriction, it sends information to the controlled node according to the PReq extended message. After receiving the configuration information, the controlled node resumes periodic operation. In the asynchronous phase of the next period, the controlled node performs the corresponding configuration update. Compared with the previous method of sending and receiving feedback through two asynchronous phases, the technology used in this solution does not require the controlled node to be disconnected from the management node. It only achieves online updates of the controlled node by modifying the period and the data transmission method. Data is transmitted through messages. Then, in the asynchronous phase, the management node does not need to perform configuration updates again, but only needs to wait for the corresponding controlled node to update. This greatly improves the working efficiency of the server and ensures the stability of the server operation.

[0056] The above embodiments do not limit the method for detecting whether the controlled node has received the PREQ message. Here, a preferred solution is proposed, which includes detecting whether each controlled node has received the PREQ extended message, including:

[0057] Enter the synchronization phase of the next cycle and receive Pres messages sent by each controlled node;

[0058] The Pres message is used to check whether each controlled node has received the PReq extended message.

[0059] It should be noted that, since there is no time limit for the cycle in this embodiment, the entry into the next cycle is generally done manually or by setting the asynchronous phase time. After receiving the corresponding Pres message, the management node needs to perform corresponding processing. In this embodiment, the specific processing method is not limited, and the control node is determined whether it has received the PREQ extended message based on the processing result. If the corresponding extended message is received, the subsequent configuration update steps can be performed.

[0060] Considering that controlled nodes typically have communication timeout protection to meet server requirements, a preferred solution is provided here. After setting the control cycle time to be arbitrarily adjustable, it also includes:

[0061] The broadcast period time modification information is sent to each controlled node so that the controlled nodes can disable the timeout protection state.

[0062] It should be noted that the timeout protection state of the controlled node provided in this embodiment is not related to the synchronous and asynchronous phase states mentioned above. Instead, it is a preset value for receiving information in a typical controlled node. If no information is received after the preset value is exceeded, the node will enter the timeout protection state. Different controlled nodes have different settings for the timeout protection state. Therefore, the specific time set for the timeout protection state and the specific protection method for the timeout protection state are not limited in this embodiment.

[0063] Considering the instability of configuration parameter updates received by the controlled node, and to ensure the controlled node completes the update and prevents subsequent server errors, a preferred solution is provided. After entering the asynchronous phase and sending the configuration update command, the following steps are also included:

[0064] Read the configuration parameters of the controlled node, and determine whether the controlled node has been configured based on the configuration parameters;

[0065] If not, an alert will be issued to prompt the user to make configuration changes.

[0066] It should be noted that this embodiment does not limit the determination of whether the controlled nodes have been configured. It is conceivable that it can be determined by logs, messages, etc. It should also be noted that this embodiment does not limit the specific methods of configuration modification and alarm. In this embodiment, by adding alarms, it is possible to verify whether the controlled nodes have been configured and prevent operational errors caused by version issues in subsequent server operation.

[0067] To address the aforementioned problems, this application also provides a method for controlling a node, applied to a controlled node, comprising:

[0068] Receive the PREQ extended message sent by the management node, and parse the configuration information according to the PREQ extended message. The management node is a node whose control cycle period is arbitrarily adjustable.

[0069] After receiving the configuration information, send feedback information to the management node;

[0070] Receive configuration update instructions sent by the management node, and update the configuration according to the instructions and configuration information.

[0071] Preferably, after receiving the PREQ extended message sent by the management node and parsing the configuration information according to the PREQ extended message, the method further includes:

[0072] The configuration information is cached, and the integrity of the configuration information in the cache space is checked.

[0073] If so, proceed to the step of sending feedback information to the management node after receiving the configuration information.

[0074] The core content of this method is the same as that in the above embodiments, except that the application scenarios are in the management node and the controlled node, respectively. Therefore, the specific embodiments refer to the above embodiments of the method applied to the management node.

[0075] The control node method provided in this embodiment is applied to the controlled node. After the management node exits the periodic restriction, it sends information to the controlled node according to the PReq extended message. After receiving the configuration information, the controlled node resumes periodic operation. In the asynchronous phase of the next period, the controlled node performs the corresponding configuration update. Compared with the previous method of sending and receiving feedback through two asynchronous phases, the technology used in this solution does not require the controlled node to be disconnected from the management node. It only achieves online updates of the controlled node by modifying the period and data transmission method, and transmits data through messages. Then, in the asynchronous phase, the management node does not need to perform configuration updates again, but only needs to wait for the corresponding controlled node to update, which greatly improves the working efficiency of the server and ensures the stability of the server operation.

[0076] In the above embodiments, the method for controlling the node has been described in detail. This application also provides embodiments corresponding to the device for controlling the node. It should be noted that this application describes the embodiments of the device part from two perspectives: one is based on the functional module, and the other is based on the hardware.

[0078] Module 1 is configured to set the control cycle time to an arbitrary adjustable value and send configuration information to each controlled node via PReq extended messages.

[0079] The detection module 2 is used to detect whether each of the controlled nodes has received the PReq extended message. If so, it returns to the setting module; otherwise, it enters the sending module.

[0080] The sending module 3 is used to set the period time of the control cycle to a preset period time, enter the asynchronous stage, and send a configuration update instruction so that the controlled node can update its configuration according to the configuration information after receiving the configuration update instruction.

[0086] The two control node devices provided in this embodiment receive cached information written by the I / O port through the information collection module, send an aggregation request to the aggregation control module, and control the aggregation control module to obtain the configuration information and cached information of the RAID card. Based on the configuration information, the aggregation array elements are obtained, and based on the aggregation array elements, the aggregation control module performs corresponding aggregation operations on the configuration information.

Compared to the original solution, this solution can prioritize merging a series of similar cached data, thereby reducing communication barriers between the RAID card and the CPU. Furthermore, since the cached data in this solution is aggregated through the RAID card, the CPU does not need to perform the aggregation operation, thus reducing the CPU load and further improving efficiency.
