[0089] Embodiment 1

[0090] The present application embodiment provides a disk group array card monitoring method, specifically, as follows Figure 1 As shown, the method disclosed in the embodiment of the present application is used to monitor the disk array card, including the following contents:

[0091] S1. In response to the server being powered on, a management component transmission protocol network is established between the baseboard management controller and the PCIe device.

[0092] like Figure 2 As shown, in order to realize the construction of the management component transmission protocol network between the baseboard management controller and the PCIe device, the connection between the baseboard management controller and the PCIe device in hardware needs to be connected in the following way, including:

[0093] The baseboard management controller has a management component transmission protocol driver; one end of the baseboard management controller is connected to one end of the PCIe switch via a PCIe link; the other end of the PCIe switch is connected to at least one PCIe device, and the PCIe device includes a disk array card; wherein one end of the baseboard management controller is also connected to the central processing unit via a PCIe link, and the other end of the central processing unit is connected to one end of the PCIe switch via a PCIe link; and / or, one end of the baseboard management controller is also connected to the integrated south bridge via a PCIe link, and the other end of the integrated south bridge is connected to one end of the PCIe switch via a PCIe link. Among them, the central processing unit usually refers to the CPU, and in some scenarios, it can also be replaced by a practical GPU; the south bridge is an important component of the motherboard chipset, which is mainly responsible for controlling the input and output parts of the motherboard, such as: hard disk, I / O interface, etc., and the integrated south bridge can also be used in this application.

[0094] Further, in response to the server powering on, building a management component transmission protocol network between the baseboard management controller and the PCIe device includes:

[0095] In response to the server power-on, the baseboard management controller is determined to be the bus owner of the management component transport protocol; the management component transport protocol driver in the baseboard management controller is triggered to send a device discovery message based on the management component transport protocol to the target PCIe device mounted on the PCIe link; in response to the feedback message initiated by the target PCIe device for the device discovery message, the baseboard management controller is triggered to assign a unique terminal identifier to the target PCIe device to achieve the establishment of a management component transport protocol network between the baseboard management controller and the PCIe device. The above-mentioned terminal identifier (EID, Endpoint ID) is the Destinaiton endpoint ID in the PCIe VDM Header in the above-mentioned MCTP message format, which is unique and is assigned by the baseboard management controller, and the subsequent interactions between the baseboard management controller and the PCIe device are all based on the EID.

[0096] After the server is powered on, the disk array card, as one or more PCIe devices, will register with the PCIe link. Similarly, the baseboard management controller will also register with the PCIe link as a device of the PCIe link. The baseboard management controller sends a device discovery message to the target PCIe mounted on the link through the PCIe link. If there is a device to feedback, the terminal identifier is assigned to the PCIe device to realize the discovery of the device. Among them, the device discovery message is a message generated based on the management component transport protocol, the management component transport protocol (MCTP, Management Component Transport Protocol). This application realizes automatic discovery and identification between devices through device discovery messages based on the MCTP protocol. The baseboard management controller can obtain the information of the PCIe device through the MCTP protocol. Through the above operation, the management component transport protocol network between the baseboard controller and the PCIe device is established, so that the baseboard management controller and each PCIe device are in the same management component transport protocol network, which is convenient for subsequent message transmission.

[0097] S2. Identify whether there is a monitorable disk array card in the PCIe device included in the management component transmission protocol network.

[0098] In order to identify the monitorable disk array card, it is first necessary to identify the monitorable disk array card in the PCIe device, and then process the disk array card in a targeted manner. In some specific implementation scenarios, the above identification management component transmission protocol network includes:

[0099] A configuration request message is sent to a target PCIe device with a terminal identifier through a management component transmission protocol driver in a baseboard management controller; the device configuration information is received and parsed through a baseboard management controller to obtain a device identifier and a message format; the baseboard management controller determines whether the target PCIe device is a monitorable disk array card according to the device identifier and the message format; wherein the device configuration information is generated by the target PCIe device in response to the configuration request message and fed back to the baseboard management controller. Specifically, the above configuration request message and device configuration information can be messages generated and transmitted based on the MCTP protocol. That is, the baseboard management controller reads some basic information of the PCIe device through the MTCP protocol, including the message format (Message Type) and device identifier supported by the device, and the device identifier includes Vendo Id (vendor identifier) ​​and Device Id (device identifier); the above Vendo Id, Device Id and Message Type are all recorded in the PCI configuration space Header for viewing.

[0100] Further, the above-mentioned determination of whether the target PCIe device is a monitorable disk array card by the baseboard management controller according to the manufacturer identification and the message format includes: determining whether the target PCIe device is a disk array card according to the manufacturer identification; in response to determining that the target PCIe device is a disk array card, judging whether the disk array card supports the communication protocol of the standard data model (PLDM, Platform Level Data Model) according to the message format; if the disk array card supports the communication protocol of the standard data model, then determining that the target PCIe device is a monitorable disk array card. It can be understood that the Vendor ID represents the manufacturer of the PCI device, and the Device ID represents the specific device produced by this manufacturer. The baseboard management controller determines whether the target PCIe device is a disk array card according to the collected Vendor Id and Device Id. And further according to the acquired message format, such as PLDM, NCSI, etc., according to the recorded message format, confirm whether PLDM is supported.

[0101] This application obtains device configuration information in advance to determine whether there is a disk array card. Only when there is a disk array card in the PCIe device in the current network and it is confirmed that the currently identified disk array card supports the communication protocol of the standard data model, will the monitoring of the disk array card be triggered to reduce resource waste.

[0102] Further, the above-mentioned determining whether the target PCIe device is a monitorable disk array card according to the device identification and the message format by the baseboard management controller also includes:

[0103] If the disk array card does not support the communication protocol of the standard data model, then the preset disk array card information table is used to find out whether the disk array card has a version of the communication protocol that supports the standard data model; if the disk array card has a specified firmware version that supports the communication protocol of the standard data model, then the firmware of the disk array card is updated to the specified firmware version; if the disk array card does not have a specified firmware version that supports the communication protocol of the standard data model, then an abnormal alarm is generated to prompt the user that there is currently no disk array card that can be monitored. The disk array information table records the information of the disk array card, the corresponding firmware version, and whether different versions support the communication protocol of the standard data model. If it is confirmed that the disk array card has a specified firmware version that supports the communication protocol of the standard data model, then the disk array card is updated to the specified firmware version, thereby overcoming the problem that the current disk array card does not support monitoring; and if the disk array card does not have a specified firmware version that supports the communication protocol of the standard data model, then the detected disk array card does not support the current monitoring method, and an abnormal alarm is generated at this time, prompting the user to perform subsequent processing, such as replacing the disk array card or starting other monitoring methods.

[0104] S3, in response to identifying that there is a monitorable disk array card in the PCIe device included in the management component transmission protocol network, triggering the baseboard management controller to start the disk array card monitoring thread and send a target monitoring command to the identified monitorable disk array card.

[0105] The target monitoring command is a command defined by a communication protocol based on a standard data model; the communication protocol of the standard data model allows data exchange between different hardware devices and management tools, and its core goals mainly include standardized data exchange, improved interoperability, and simplified management. However, since disk array cards of different manufacturers and models may use different monitoring interfaces and protocols, their compatibility is poor. In view of this, the present application uses the communication protocol of the standard data model to implement a technology for monitoring disk array cards.

[0106] In specific implementation scenarios, such as Figure 3The timing diagram shown, in response to identifying the monitorable disk array card in the PCIe device included in the management component transmission protocol network, triggering the baseboard management controller to start the disk array card monitoring thread and send the target monitoring command to the identified monitorable disk array card, including: after the disk array card monitoring thread is started, the management component transmission protocol driver in the baseboard management controller uses the target monitoring command as the data of the management component transmission protocol and encapsulates it into a monitoring management component transmission protocol message, wherein the monitoring management component transmission protocol message includes the target terminal identifier; the management component transmission protocol driver in the baseboard management controller transmits the monitoring management component transmission protocol message to the central processing unit and / or the integrated south bridge; through the central processing unit and / or the integrated south bridge, the monitoring management component transmission protocol message is forwarded to the target disk array card in the monitorable disk array card corresponding to the target terminal identifier. It can be understood that after the above-mentioned disk array card monitoring thread is started, the baseboard management controller cyclically sends the target monitoring command to the monitorable disk array card to realize real-time monitoring of the disk array card.

[0107] After the target disk array card receives the monitoring management component transmission protocol message, the target disk array card feeds back the disk array card data matching the target monitoring command to the baseboard management controller, which specifically includes: the target disk array card responds to the received monitoring management component transmission protocol message, unpacks the monitoring management component transmission protocol message to obtain the target monitoring command; the target disk array card parses the target monitoring command based on the communication protocol of the standard data model, and extracts the disk array card data matching the target monitoring command; the target disk array card generates target response data corresponding to the extracted disk array card data matching the target monitoring command based on the communication protocol of the standard data model; the target disk array card encapsulates the target response data into a feedback management component transmission protocol message; the target disk array card transmits the feedback management component transmission protocol message to the central processing unit and / or the integrated south bridge, and feeds back the feedback management component transmission protocol message to the baseboard management controller through the central processing unit and / or the integrated south bridge. It is understandable that a series of PLDM commands are defined in advance in the disk array card according to monitoring requirements, including but not limited to disk array card status query, disk array card configuration query, disk array card configuration, and disk array card fault alarm; the specific PLDM Message includes PLDM Header and PLDM MessagePayload. Different PLDM Types in the PLDM Header belong to different functional areas, and the above PLDM commands have been specifically defined on the PLDM Type. For example, the newly added PLDM Command Code is 0x60, and the PLDM Message Payload can obtain information on different areas of the disk array card according to different parameters. If the parameter is 0, the basic information of the disk array card is obtained, and if it is 1, the attribute information of the disk array card is obtained.

[0108] Based on the terminal identification set in the above content, this application sends a target monitoring command to each monitorable disk array card, thereby obtaining relevant information of the monitorable disk array card; and after receiving the target monitoring command, the monitorable disk array card obtains the corresponding information, and feeds the obtained information back to the baseboard management controller according to the same protocol and link. Through the defined standardized command format, the compatibility of the monitoring method provided by this application with a variety of monitorable disk array cards is ensured, and the target monitoring command is encapsulated into the MTCP protocol, which greatly speeds up the transmission speed of the command and further improves the timeliness of monitoring.

[0109] S4. Obtaining disk array card data that matches the target monitoring command and is fed back by the monitorable disk array card through the baseboard management controller to implement monitoring of the disk array card.

[0110] After receiving the feedback management component transmission protocol message, the baseboard management controller obtains the disk array card data matching the target monitoring command fed back by the monitorable disk array card through the baseboard management controller, specifically including: the baseboard management controller receives and unpacks the feedback management component transmission protocol message to obtain the target response data; the baseboard management controller parses the target response data based on the communication protocol of the standard data model to obtain the disk array card data.

[0111] In some specific implementation scenarios, if a monitored disk card fails, the present application also proposes receiving and parsing the fault management component transmission protocol message through the baseboard management controller to obtain fault information; parsing the fault information through the baseboard management controller based on the communication protocol of the standard data model to obtain the fault event log, and performing a fault recovery operation matching the fault event log according to a preset fault handling strategy; wherein the fault information is information generated by the communication protocol of the monitored disk array card based on the standard data model and corresponds to the recorded fault event log.

[0112] Specifically, when a disk card fails, the disk array card automatically records a fault event log, and reorganizes the fault event log into fault information based on a communication protocol of a standard data model, and then encapsulates it in a management component transmission protocol message for transmission. The fault event log includes at least an event code and an event description, wherein the event code is a unique identifier of an alarm type. After receiving the fault information, the baseboard management controller immediately parses to obtain the event code, etc., and automatically searches for a fault repair operation matching the event code according to a pre-set fault repair strategy to achieve automatic fault repair. In addition, the baseboard management controller can also trigger a fault alarm in response to receiving the fault information, and send the fault information to the administrator so that the administrator can perform subsequent fault handling operations. Among them, the fault information can be sent to the administrator via email, SMS or other means to ensure that the administrator can understand and handle the fault of the disk array card in a timely manner. Timely handling of faults is achieved, thereby ensuring the security and stability of data storage; allowing administrators to take action at the beginning of the problem, thereby preventing data loss or system crash, and further improving the reliability and stability of the system.

[0113] Further, in some embodiments, the management component transmission protocol driver in the baseboard management controller transmits the monitoring management component transmission protocol message to the central processing unit and / or the integrated south bridge through the PCIe transmission layer, and receives the feedback management component transmission protocol message and the fault management component transmission protocol message forwarded by the central processing unit and / or the integrated south bridge through the PCIe transmission layer; the central processing unit and / or the integrated south bridge forwards the monitoring management component transmission protocol message to the monitorable disk array card through the PCIe transmission layer, and receives the feedback management component transmission protocol message and the fault management component transmission protocol message generated by the monitorable disk array card through the PCIe transmission layer. By utilizing the high-speed transmission capability of the PCIe protocol and adopting a point-to-point serial communication method, each device has its own dedicated data channel, which greatly speeds up the transmission speed and efficiency of the disk array card data between the disk array card and the baseboard management controller, reduces the delay in the monitoring process, and further realizes the real-time monitoring of the disk array card status.

[0114] In addition, the embodiment of the present application also discloses setting a unified management interface on the baseboard management controller. Specifically, the present application discloses using the baseboard management controller to parse whether the management instruction received by the unified management interface contains a disk array card monitoring instruction; in response to parsing that the management instruction contains a disk array card monitoring instruction, the baseboard management controller feeds back the stored disk array card data that can be matched with the monitorable disk array card. By accessing the remote management terminal on the interface, the administrator is provided with the function of managing all disk array cards. The administrator does not need to be familiar with the specific management methods of different devices, which simplifies the management method and improves the management efficiency.

[0115] In addition, the present application also proposes a method for handling abnormal interactions between disk array cards and baseboard management controllers, specifically including: if the baseboard management controller does not detect the existence of feedback monitoring management component transmission protocol feedback back to the baseboard management controller within a preset time period after sending a monitoring management component transmission protocol message to the disk array card, then trigger an abnormal mechanism; the baseboard management controller sends a detection message to the disk array card, wherein the detection message is a message with a smaller byte size generated based on the monitoring management component transmission protocol; if the baseboard management controller can receive feedback from the disk array card for the detection message within a preset time period, then rebuild the above-mentioned management component transmission protocol network to eliminate possible problems; if the baseboard management controller fails to receive feedback from the disk array card for the detection message within a preset time period, then trigger an abnormal alarm to prompt the user to repair the current communication management component transmission protocol network. The above-mentioned preset time period is set by the management personnel based on factors such as the transmission rate of the management component transmission protocol message and the current processing capacity of the baseboard management controller, and this application does not impose any restrictions on this.

[0116] This application utilizes the standardized data exchange characteristics of PLDM, combined with the communication specifications of MCTP and the high-speed transmission capability of PCIE, to solve the technical problems of compatibility, efficiency, real-time and management complexity in traditional RAID card monitoring methods, and provides an efficient, real-time, compatible and easy-to-manage disk array card monitoring method. Compared with traditional methods, these advantages make it have broad application prospects in data centers, cloud computing, enterprise-level storage, scientific research and high-performance computing.
