[0106] The embodiment of the application provides a kind of disk group array card monitoring method, in some embodiments, as shown in Figure 1, the monitoring of disk array card is realized using the method disclosed in the embodiment of the application, including the following contents:

[0107] S1, in response to server power on, build the management component transmission protocol network between baseboard management controller and PCIe (Peripheral Component Interconnect Express, a kind of high-speed serial computer expansion bus standard) equipment.

[0108] As shown in Figure 2, to build the management component transmission protocol network between baseboard management controller and PCIe equipment, the connection between baseboard management controller and PCIe equipment on hardware needs to be connected in the following way, including:

[0109] There is management component transmission protocol driver in baseboard management controller;The first end of baseboard management controller is connected with the first end of PCIe switch by PCIe link;The second end of PCIe switch is connected with at least one PCIe equipment, and PCIe equipment includes disk array card;Wherein, the second end of baseboard management controller is also connected to the first end of central processing unit by PCIe link, and the second end of central processing unit is connected to the third end of PCIe switch by PCIe link;And / or, the second end of baseboard management controller is also connected to the first end of integrated south bridge by PCIe link, and the second end of integrated south bridge is connected to the third end of PCIe switch by PCIe link;Wherein, central processing unit generally refers to CPU (Central Processing Unit, central processing unit), GPU (Graphics Processing Unit, graphics processor) can be replaced in some scenarios;South bridge is an important component of motherboard chipset, and it is mainly responsible for controlling the input and output part of motherboard, such as hard disk, I / O (Input / Output, input / output) interface, etc., integrated south bridge can also be used in the application.

[0110] Further, the above-mentioned response to server power on, build the management component transmission protocol network between baseboard management controller and PCIe equipment, including:

[0111] In response to the server being powered on, the baseboard management controller is determined to be a bus owner of a management component transport protocol; a 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 a target PCIe device mounted on the PCIe link; in response to a feedback message initiated by the target PCIe device to the device discovery message, the baseboard management controller is triggered to assign a unique terminal identifier to the target PCIe device, so as to realize the establishment of a management component transport protocol network between the baseboard management controller and the PCIe device. The terminal identifier (EID, Endpoint ID) is the Destination endpoint ID in the PCIe VDM Header in the MCTP (Management Component Transport Protocol) message format, which is unique, assigned by the baseboard management controller, and subsequent interaction between the baseboard management controller and the PCIe device is based on the EID.

[0112] After the server is powered on, the disk array card as one or more of the PCIe devices will be registered to the PCIe link. The same baseboard management controller will also be registered to the PCIe link as a device of the PCIe link. The baseboard management controller sends a device discovery message to the target PCIe device mounted on the link through the PCIe link, and assigns a terminal identifier to the PCIe device in response to determining that there is a device to feedback, so as to realize the discovery of the device. The device discovery message is a message generated based on the management component transport protocol, and the management component transport protocol. The present application realizes automatic discovery and identification between devices through the device discovery message 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.

[0113] S2, identify whether there is a monitorable disk array card in the PCIe device contained in the management component transport protocol network.

[0114] In order to realize the identification of the monitorable disk array card, it is necessary to identify the monitorable disk array card existing in the PCIe device first, and then process the disk array card accordingly. In some implementation scenarios, the above identification of whether there is a monitorable disk array card in the PCIe device contained in the management component transport protocol network includes:

[0115] The baseboard management controller transmits a configuration request message to a target PCIe device with a terminal identifier through a management component transmission protocol driver; the baseboard management controller receives and analyzes device configuration information 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 is fed back to the baseboard management controller. In some embodiments, the above-mentioned 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) supported by the device and the device identifier, which includes the Vendor ID (manufacturer identifier) and the Device Id (device identifier); the above-mentioned Vendor ID, Device Id and Message Type are recorded in the PCIe configuration space Header for viewing.

[0116] Further, the above-mentioned determination by the baseboard management controller whether the target PCIe device is a monitorable disk array card according to the device identifier and the message format includes: determining whether the target PCIe device is a disk array card according to the device identifier; 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; in response to determining that the disk array card supports the communication protocol of the standard data model, 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 PCIe device, and the Device ID represents the device produced by the manufacturer, and 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 obtained message format, such as PLDM (Platform-Level Data model, platform-level data model), NCSI (Network Controller Sideband Interface, network controller sideband interface), etc., whether it supports PLDM is confirmed according to the message format recorded therein.

[0117] The present application determines whether there is a disk array card in advance by obtaining device configuration information, and only when there is a disk array card in the PCIe devices in the current network and it is confirmed that the identified disk array card supports the communication protocol of the standard data model, the monitoring of the disk array card is triggered, which reduces resource waste.

[0118] Further, the above determining, by the baseboard management controller, whether the target PCIe device is a monitorable disk array card according to the device identifier and the message format further comprises:

[0119] In response to determining that the disk array card does not support the communication protocol of the standard data model, it is determined whether the disk array card has a specified firmware version that supports the communication protocol of the standard data model according to a preset disk array card information table. In response to determining that the disk array card has the specified firmware version that supports the communication protocol of the standard data model, the firmware of the disk array card is updated to the specified firmware version. In response to determining that the disk array card does not have the specified firmware version that supports the communication protocol of the standard data model, an abnormal alarm is generated to prompt a user that there is no monitorable disk array card at present. The disk array information table records information of disk array cards, corresponding firmware versions, and whether different versions support the communication protocol of the standard data model. In response to confirming that the disk array card has the specified firmware version that supports the communication protocol of the standard data model, 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. In response to confirming that the disk array card does not have the specified firmware version that supports the communication protocol of the standard data model, the detected disk array card does not support the current monitoring method, and an abnormal alarm is generated to prompt the user to perform subsequent processing, such as replacing the disk array card or starting other monitoring methods.

[0120] S3, in response to identifying that the PCIe device contained in the management component transmission protocol network has a monitorable disk array card, triggering the baseboard management controller to start a disk array card monitoring thread and issuing a target monitoring command to the identified monitorable disk array card.

[0121] The target monitoring command is a command defined based on the communication protocol of the standard data model. The communication protocol of the standard data model allows data exchange between different hardware devices and management tools, and the core goals mainly include standardizing data exchange, improving interoperability, and simplifying management. However, different manufacturers and models of disk array cards may use different monitoring interfaces and protocols, and the compatibility is poor. Therefore, the application uses the communication protocol of the standard data model to implement the monitoring technology of the disk array card.

[0122] In an implementation scenario, as shown in the timing diagram of FIG. 3, the above-mentioned response to identifying the monitorable disk array card in the PCIe device contained in the BMC transport protocol network triggers the baseboard management controller to start the disk array card monitoring thread and issue the target monitoring command to the identified monitorable disk array card, including: after the disk array card monitoring thread is started, the BMC transport protocol driver in the baseboard management controller encapsulates the target monitoring command as the data of the BMC transport protocol and into a monitoring BMC transport protocol packet, wherein the monitoring BMC transport protocol packet includes a target terminal identifier; the BMC transport protocol driver in the baseboard management controller transmits the monitoring BMC transport protocol packet to the central processor and / or the integrated south bridge; and the central processor and / or the integrated south bridge forwards the monitoring BMC transport protocol packet 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 sends the target monitoring command to the monitorable disk array card in a loop to realize real-time monitoring of the disk array card.

[0123] After receiving the monitoring management component transmission protocol message, the target disk array card feeds back disk array card data matched with the target monitoring command to the baseboard management controller, including: the target disk array card, in response to the received monitoring management component transmission protocol message, unseals 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 disk array card data matched with the target monitoring command; the target disk array card generates target response data corresponding to the extracted disk array card data matched with 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; and the target disk array card transmits the feedback management component transmission protocol message to the central processor and / or integrated south bridge, and feeds back the feedback management component transmission protocol message to the baseboard management controller through the central processor and / or integrated south bridge. It can be understood that a series of PLDM commands are defined in the disk array card in advance according to monitoring requirements, including but not limited to disk array card state query, disk array card configuration query, disk array card configuration, and disk array card fault alarm. The PLDM Message message includes a PLDM Header header and a PLDM Message Payload message payload; different PLDM Type in the PLDM Header belongs to different functional fields, and the above-mentioned PLDM commands have been defined on the PLDM Type. For example, a new PLDM Command Code is 0x60, and different area information of the disk array card can be obtained in the PLDM Message Payload according to different parameters. The parameter is 0 to obtain the basic information of the disk array card, and 1 to obtain the attribute information of the disk array card.

[0124] Based on the terminal identifier set in the foregoing content, the target monitoring command is sent to each monitorable disk array card, so as to obtain the related information of the monitorable disk array card. After receiving the target monitoring command, the monitorable disk array card obtains the corresponding information, and feeds back the obtained information 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 the application to various monitorable disk array cards is ensured, and the target monitoring command is encapsulated into the MTCP protocol, which greatly accelerates the transmission speed of the command and further improves the timeliness of the monitoring.

[0125] S4, obtaining the disk array card data matched with the target monitoring command fed back by the monitorable disk array card through the baseboard management controller, to realize monitoring of the disk array card.

[0126] After receiving the feedback management component transport protocol message, the substrate management controller obtains the disk array card data that matches the target monitoring command from the feedback of the monitorable disk array card through the substrate management controller, including: the substrate management controller receives and unseals the feedback management component transport protocol message to obtain target response data; the substrate management controller parses the target response data based on the communication protocol of the standard data model to obtain the disk array card data.

[0127] In some implementation scenarios, if the monitorable disk card fails, the application further proposes to receive and analyze the fault management component transport protocol message through the substrate management controller to obtain fault information; the substrate management controller parses the fault information based on the communication protocol of the standard data model to obtain the fault event log, and performs the fault recovery operation matched with the fault event log according to the preset fault processing strategy; wherein the fault information is the information corresponding to the recorded fault event log generated by the monitorable disk array card based on the communication protocol of the standard data model.
