Description

Technical Field

[0001] The present invention relates to the technical field of storage management, and in particular to a configuration method, device, equipment, medium and product of a disk array card. Background Art

[0002] Traditional RAID (Redundant Array of Independent Disks) cards are PCIe (Peripheral Component Interconnect express, a high-speed serial computer expansion bus standard) devices on computer systems. They are connected to the host through the PCIe bus and use the manufacturer's customized SCSI (Small Computer System Interface) protocol to exchange commands in the upper layer business to achieve the interaction of configuration data between the host and the RAID card. CLI (Command Line Interface) is a text-based command line interface that interacts with computer programs or operating systems by entering commands to complete corresponding operations.

[0003] The RAID card CLI configuration management tool is a configuration management software developed on the host's operating system. Users can configure and manage the RAID card by entering specified commands. Due to the complexity of the RAID card configuration management functions, the mainstream RAID card CLI configuration management tools on the market have developed nearly hundreds of CLI commands. Since there is no unified standard protocol in the industry to define RAID card configuration tools, most command definitions require the expansion of the manufacturer-defined communication protocol used by the upper-layer business between the host and the RAID card. The commands developed in this way are numerous and have poor scalability. New CLI commands need to be developed for the addition or modification of RAID card functions, and the upper-layer business communication between the host and the RAID card needs to be expanded to use the manufacturer-defined command protocol to achieve it. Due to the differences in the management commands and upper-layer business communication protocols customized by each manufacturer, the communication interface between the RAID card controller and the host configuration management tool is incompatible with each other.

[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0068] The RAID card CLI configuration management tool is a configuration management software developed on the host's operating system. Users can configure and manage the RAID card by entering specified commands. Due to the complexity of the RAID card configuration management functions, the mainstream RAID card CLI configuration management tools on the market have developed nearly hundreds of CLI commands. Since there is no unified standard protocol in the industry to define RAID card configuration tools, most command definitions require the expansion of the manufacturer-defined communication protocol used by the upper-layer business between the host and the RAID card. The commands developed in this way are numerous and have poor scalability. New CLI commands need to be developed for the addition or modification of RAID card functions, and the upper-layer business communication between the host and the RAID card needs to be expanded to use the manufacturer-defined command protocol to achieve it. Due to the differences in the management commands and upper-layer business communication protocols customized by each manufacturer, the communication interface between the RAID card controller and the host configuration management tool is incompatible with each other.

[0069] To this end, the embodiments of the present application disclose a disk array card configuration method, device, equipment, medium and product, which can provide an efficient and universal RAID card configuration method to quickly and accurately configure the RAID card.

[0070] Figure 1 This is an architecture diagram of a configuration method for a disk array card disclosed in an embodiment of the present application, wherein the configuration command issued by the user on the command line interface is the command issued by the host, and the RAID card operation can be abstracted as the command line interface tool in the host and the RAID controller interacting with the JSON data information of the operation object to read and set the attribute value of the RAID object and complete the RAID management operation. Each attribute operation interaction is called a RAID management command operation.

[0071] On the host side, after the command line interface tool is successfully installed on the operating system, the user uses the defined command line format to issue configuration commands, which are then parsed and encapsulated into custom commands in the corresponding NVMe Admin command set by the command line interface tool, namely the target submission command described below, and then the NVME driver provided by the operating system is called to send the command to the RAID card through the PCIE bus.

[0072] On the RAID card side, after the chip firmware receives the command from the host, it parses the command according to the protocol, executes the command and returns a completion command, which is finally returned to the host through the bus. The host driver returns the returned completion command to the command line interface tool, and the command line interface tool displays the configuration results on the command line interface.

[0073] See also Figure 2 As shown, the embodiment of the present application discloses a method for configuring a disk array card, which is applied to a preset command line interface tool, and the method includes:

[0074] Step S11: parsing the acquired configuration command that meets the preset command line format to obtain configuration parameter information.

[0075] In this embodiment, the command line interface tool predefines a preset command line format, and after obtaining the configuration command, if it meets the preset command line format, the command line interface tool parses the configuration command to obtain configuration parameter information. Specifically, the command line interface tool is a RAID-CLI configuration tool.

[0076] Specifically, the preset command line format includes a first part for defining the function parameters of the command, a second part for defining the operation object parameters of the command, and a third part for defining the attribute configuration parameters of the command. In this embodiment, the command line format of RAID-CLI is defined as follows:

[0077] raidcli <command> <[object]> <args>];

[0078] It should be pointed out that the raidcli command line format mainly consists of three parts: command part <command> , object part <[object]>, parameter part [ <args>].

[0079] The definitions of each part are as follows:

[0080] 1. Command part <command> :verb + [object | property]. It is used to define the function parameters of the command, that is, the main function to be performed, which is identified by a combination of a verb + object / property.

[0081] Wherein, the function parameter is any one of the query function parameter and the configuration function parameter; wherein, the query function parameter corresponds to the query command, and the configuration function parameter corresponds to any one of the add command, modify command and delete command. It can be understood that in the RAID-CLI configuration tool, commands are mainly divided into query commands and configuration commands, corresponding to the query function and configuration function, namely, the functions of adding, modifying, deleting and querying the RAID card. Wherein, the definition of verb is shown in Table 1:

[0082] Table 1 Definition of verb

[0083]

[0084] In addition to the main functions mentioned in Table 1, its functions can also be expanded, such as "start: start an operation", "stop: stop an operation", "suspend: pause an operation", "resume: resume a suspended operation", "expand: expand the size of the volume", "import: import external configuration to disk", etc.

[0085] 2. Object part <[object]>: / kx; k represents the abbreviation of the object, and x represents the identification value of the operation object.

[0086] First of all, it should be pointed out that the business objects in the disk array card include but are not limited to controllers, arrays, physical disks and logical volumes; accordingly, the operation object parameters correspond to any object in the controller, array, physical disk and logical volume, and the attribute configuration parameters correspond to the attribute values ​​of any business object in the disk array card.

[0087] It can be understood that in the RAID card system, according to the division of the operation business objects in the RAID card, four business objects are defined, namely, controller, array, logical volume and physical disk. The ID (identification number) of each business object type is shown in Table 2:

[0088] Table 2 Business object ID classification

[0089]

[0090] Furthermore, in the RAID card system, the characteristics and status of each object can be represented by a series of attributes, so a unique ID is also defined for the attributes of each object. Among them, for the controller, its attributes may include version number, serial number, controller type, number of controllers, etc.; for the physical disk, its attributes may include disk identification, disk type, disk status, disk capacity, etc.; for the array, its attributes may include identification, level, name, status, etc.; for the logical volume, its attributes may include identification, name, capacity, status, etc.; as shown in Table 3:

[0091] Table 3 Classification of object attribute IDs

[0092]

[0093] The RAID card CLI supports the command descriptions of the objects in Table 4 to define the business objects operated by the command. If there is no object, it represents a system command, including system help commands, query RAID card version commands, and system show commands.

[0094] Table 4 Command description

[0095]

[0096] 3. Parameters <args>]:[--key= <value> | -k <value>]; When describing a parameter, [] means that the parameter is optional, --key= <value>Indicates that the value of the parameter key is the full description of value, -k <value>The value of the parameter key is an abbreviation of value. When entering command parameters, both formats are supported. The parameter key of the command can correspond to the attributes of the four business objects in the RAID card. When the NVME custom command data area is encapsulated, the key can directly correspond to the ID of the object attribute. Therefore, when configuring one or some attributes, the attributes of these objects can be carried as command parameters for configuration. The host manages and controls the RAID system by reading or setting the attribute values ​​of the object. Therefore, the configuration management function of the RAID card is the configuration management function of the above four object attributes.

[0097] Step S12: Repackage the first target area of ​​the first original management command in the NVMe protocol using the configuration parameter information to construct a target submission command.

[0098] In this embodiment, the command line interface tool needs to use configuration parameter information to construct a target submission command, specifically, use the configuration parameter information to re-encapsulate the first target area of ​​the first original management command in the NVMe (Non-Volatile Memory express, non-volatile memory host controller interface specification) protocol, that is, this application fills the configuration parameter information into the first target area of ​​the first original management command to achieve customization of the first original management command, and this application adopts the mainstream NVMe protocol transmission in the storage field, the command transmission rate is faster, the NVME driver has been integrated in the mainstream operating system kernel, and it is more practical.

[0099] Step S13: sending the target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command.

[0100] In this embodiment, the command line interface tool calls the driver interface provided by the host operating system to send the constructed target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command. Specifically, the RAID-CLI configuration tool issues commands to manage the configuration of the RAID card, that is, the host completes the configuration management and control functions of the RAID card system by reading or setting the attribute value of the object. That is, the present application realizes the configuration management of the disk array card by constructing a target submission command through the command line interface tool to configure the attributes of a business object in the disk array card.

[0101] Step S14: Obtain a target completion command constructed based on the NVMe protocol and sent by the disk array card after completing the configuration operation, and display the attribute configuration result in the command line interface; wherein the target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol.

[0102] In this embodiment, after completing the configuration operation, the disk array card will send a target completion command based on the NVMe protocol. The target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol. After receiving the target completion command, the command line interface tool displays the attribute configuration result in the command line interface, thereby realizing a complete disk array card configuration process. In this way, the present application realizes the configuration management of the disk array card using the original management command of the NVME protocol under the command line interface tool.

[0103] It can be seen that the present application parses the obtained configuration command that meets the preset command line format through a preset command line interface tool to obtain configuration parameter information; uses the configuration parameter information to repackage the first target area of ​​the first original management command in the NVMe protocol to construct a target submission command; sends the target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command; obtains the target completion command constructed based on the NVMe protocol sent by the disk array card after completing the configuration operation, and displays the attribute configuration result in the command line interface; wherein the target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol.

[0104] Beneficial effects: A preset command line format is set in the present application. After the command line interface tool obtains the configuration command, if it satisfies the preset command line format, the configuration command is parsed to obtain the configuration parameter information. Further, the command line interface tool needs to use the configuration parameter information to construct a target submission command, specifically to re-encapsulate the first target area of ​​the first original management command in the NVMe protocol using the configuration parameter information, that is, the present application fills the configuration parameter information into the first target area of ​​the first original management command to realize the customization of the first original management command, and the present application adopts the mainstream NVMe protocol transmission in the storage field, the command transmission rate is faster, the NVME driver has been integrated in the mainstream operating system kernel, and it is more practical. The command line interface tool sends the constructed target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command. That is, the present application realizes the configuration management of the disk array card by constructing a target submission command through the command line interface tool to configure the attributes of a business object in the disk array card. In addition, after completing the configuration operation, the disk array card will send a target completion command based on the NVMe protocol. The target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol. After receiving the target completion command, the command line interface tool displays the attribute configuration result in the command line interface, thereby realizing the complete disk array card configuration process. In this way, the present application realizes the configuration management of the disk array card using the original management command of the NVME protocol under the command line interface tool.

[0105] See also Figure 3 As shown, the embodiment of the present application discloses a specific method for configuring a disk array card. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, it includes:

[0106] Step S21: Obtain the configuration command issued by the user through the command line interface. If the configuration command meets the preset command line format, parse the configuration command to obtain target function parameters, target operation object parameters and target attribute configuration parameters.

[0107] In this embodiment, the user issues a configuration command in the command line interface. If the configuration command meets the preset command line format, the command line interface tool parses the configuration command to obtain target function parameters, target operation object parameters and target attribute configuration parameters.

[0108] Step S22: Use the target function parameters to set the operation code field of the submission queue entry, write the target function parameters and the target operation object parameters into the target control area of ​​the submission queue entry, and write the target attribute configuration parameters into the target data area of ​​the submission queue entry to construct a target submission command.

[0109] In this embodiment, it should be pointed out that the upper-layer service communication of the RAID card adopts the management commands customized by the NVMe protocol. The RAID card NVMe management commands belong to the manufacturer-defined command type in the NVMe Admin command set. These commands can only be submitted to the NVMe Admin queue. The NVMe standard defines the SQE (Submission Queue Entry) structure and CQE (Completion Queue Entry) structure of the basic manufacturer-defined commands.

[0110] The first original management command mentioned above is a submission queue entry in the Admin queue, and the first target area specifically includes an operation code field, a target control area, and a target data area.

[0111] Correspondingly, when the first target area of ​​the first original management command in the NVMe protocol is repackaged using configuration parameter information such as target function parameters, target operation object parameters and target attribute configuration parameters, the operation code field of the submission queue entry is set using the target function parameters, the target function parameters and the target operation object parameters are written into the target control area of ​​the submission queue entry, and the target attribute configuration parameters are written into the target data area of ​​the submission queue entry to construct the target submission command.

[0112] The target control area is specifically the CDW10 field to the CDW15 field in the submission queue entry structure, and the target data area is specifically the data pointer field in the submission queue entry structure. CDW (Command Descriptor Word) is a command descriptor word.

[0113] The structure of the submission queue entry is shown in Table 5:

[0114] Table 5 Structure of a submission queue entry

[0115]

[0116] From the above content, we can know that the principles of building custom commands are:

[0117] The Operation Code (OPC) field defines the classification identifier of the extended command, which is used to indicate whether it is a query command or a configuration command. Query commands correspond to query commands, and configuration commands correspond to add, delete, and modify commands.

[0118] CDW10 to CDW15 define the control area of ​​the command, define the operation object of the command, the operation command type, the data area size and other parameters. The operation object includes various business objects defined by the Raid card, and the operation type includes actions such as adding, deleting, modifying and checking the Raid card. CDW10 defines the size of the data cache area for storing data, CDW12 defines the operation object and operation type of the command, and CDW13 defines the identifier of the operation object of the command. In other words, the control area is used to encapsulate the command part and the operation object part of the CLI command.

[0119] DPTR defines the data area of ​​the object. The operation attributes of the operation or query object will be encapsulated in the area to facilitate the transmission of object attribute information. In other words, the data area is used to encapsulate the parameter part of the CLI command.

[0120] Specifically, the above-mentioned writing of the target function parameter and the target operation object parameter into the target control area of ​​the submission queue entry includes: determining the space size of the data buffer area for storing the attribute configuration result applied in advance, and determining the target identification number corresponding to the target operation object parameter according to the correspondence relationship between the operation object and the identification number established in advance; writing the space size into the CDW10 field, writing the target function parameter and the target operation object parameter into the CDW12 field, and writing the target identification number into the CDW13 field. That is, the present application writes the space size of the data buffer area for storing the attribute configuration result applied in advance into the CDW10 field, writes the target function parameter and the target operation object parameter into the CDW12 field, and writes the target identification number corresponding to the target operation object parameter determined according to the correspondence relationship between the operation object and the identification number established in advance into the CDW13 field, thereby completing the construction of the target submission command.

[0121] Furthermore, the writing of the target attribute configuration parameters into the target data area of ​​the submission queue entry includes: encapsulating the target attribute configuration parameters in the target data area of ​​the submission queue entry based on the JSON data format. It should be noted that the data information encapsulation format in the PRPs adopted in the DPTR in the NVMe custom command adopts the JSON mode encapsulation, so the attributes of the object are represented in the JSON data format in the data structure, and each attribute of each object defines a unique ID as the key, and the value of the attribute is the value corresponding to the key.

[0122] Step S23: sending the target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command.

[0123] Step S24: obtaining a target completion command constructed based on the NVMe protocol and sent by the disk array card after completing the configuration operation, and displaying the attribute configuration result in a command line interface; wherein the target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol.

[0124] In this embodiment, the second original management command is a completion queue entry in the Admin queue, and the second target area includes a status field and a CDW0 field.

[0125] Therefore, the process of repackaging the second target area of ​​the second original management command in the NVMe protocol includes: writing the execution status information of the target submission command into the status field; wherein the execution status information includes first status information for characterizing successful execution and second status information for characterizing failed execution; and writing the data length of the attribute configuration result obtained by the disk array card after completing the configuration operation into the CDW0 field.

[0126] The structure of the completion queue entry is shown in Table 6:

[0127] Table 6 Completion Queue Entry Structure

[0128]

[0129] Therefore, the execution status information of the target submission command is written into the command result status field, that is, whether the configuration command is executed successfully or failed, and the data length of the attribute configuration result is written into the CDW0 field.

[0130] Furthermore, the above method also includes: using the data cache to receive the attribute configuration result sent by the disk array card after performing the corresponding configuration operation on the target attribute of the target business object based on the target submission command; correspondingly, the attribute configuration result is displayed in the command line interface, including: displaying the attribute configuration result read from the data cache based on the target completion command in the command line interface. That is, the command line interface tool will use the pre-applied data cache to receive the attribute configuration result transmitted by the disk array card. When receiving the target completion command based on the NVMe protocol sent by the disk array card after completing the configuration operation, if it is necessary to display the attribute configuration result in the command line interface, the attribute configuration result of the corresponding length is read from the data cache based on the data length in the target completion command, and displayed in the command line interface.

[0131] The disk array card encapsulates the attribute configuration result based on the JSON data format, and writes the encapsulated attribute configuration result into the data buffer area. That is, the disk array card constructs the returned attribute configuration result into a JSON data structure, writes it into the data buffer area pre-applied by the command line interface tool, and writes the execution status of the command into the CQE.

[0132] Specifically, the process in which the disk array card performs a corresponding configuration operation on the target attribute of the target business object based on the target submission command includes: parsing the target control area by the disk array card to determine the target business object of this operation based on the target operation object parameter, and determining the operation command of this operation based on the target function parameter; wherein the operation command is any one of a query command, an add command, a modify command and a delete command; parsing the target data area by the disk array card to determine the target attribute of this configuration based on the target attribute configuration parameter, so as to perform the configuration operation corresponding to the operation command on the target attribute of the target business object. That is, after the disk array card obtains the target submission command, it parses the target control area to determine the target business object of this operation based on the target operation object parameter, and determines the operation command of this operation based on the target function parameter, that is, determines whether the operation command is a query command, an add command, a modify command and a delete command, and further, it is necessary to parse the target data area to determine the target attribute of this configuration based on the target attribute configuration parameter, so as to perform the configuration operation corresponding to the operation command on the target attribute of the target business object.

[0133] For more specific processing procedures of the above steps S23 and S24, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described in detail here.

[0134] It can be seen that this application forms a set of basic principles for command naming based on the encapsulation type format of the NVMe Admin custom command and the RAID card configuration management. The commands are divided into a control area and a data area. The control area encapsulates the operation object, operation type and object identification parameters; the data area encapsulates the attribute information of the configuration or query object. The data area uses the object attribute template method to encapsulate and parse the data in JSON format, making the NVME command definition more extensible. In this way, this application only needs to expand the original management command of NVMe Admin, and implement the configuration of the RAID card by defining an attribute or attribute combination belonging to the operation object. The object attribute is added or modified. The NVMe Admin custom command only needs to add or modify the attribute in the JSON data encapsulated in the DPTR data area. The NVME protocol does not need to be expanded or modified, and the protocol is highly compatible and extensible. Moreover, after the traditional hundreds of commands are defined and implemented through this solution, the number of commands is reduced by about 10 times, and the newly added configuration features of the RAID card are equivalent to the newly added object attributes of the system. The CLI command only needs to expand some parameters to achieve strong extensibility.

[0135] See also Figure 4 As shown, the embodiment of the present application discloses a configuration method of a disk array card, which is applied to the disk array card. The method includes:

[0136] Step S31: Obtain a target submission command sent by a preset command line interface tool; wherein the target submission command is a command obtained by the command line interface tool repackaging and constructing the first target area of ​​the first original management command in the NVMe protocol using configuration parameter information, and the configuration parameter information is information obtained by the command line interface tool after parsing the obtained configuration command that meets the preset command line format.

[0137] Step S32: Based on the target submission command, perform corresponding configuration operations on the target attributes of the target business object, and after completing the configuration operation, send a target completion command constructed based on the NVMe protocol to the command line interface tool, so that the command line interface tool can display the attribute configuration results in the command line interface; wherein, the target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol.

[0138] It can be seen that in this application, the disk array card obtains the target submission command sent by the preset command line interface tool, which is a command obtained by the command line interface tool using the configuration parameter information to re-encapsulate and construct the first target area of ​​the first original management command in the NVMe protocol. That is, the command line interface tool fills the configuration parameter information into the first target area of ​​the first original management command to realize the customization of the first original management command, and this application adopts the mainstream NVMe protocol transmission in the storage field, the command transmission rate is faster, and the NVME driver has been integrated in the mainstream operating system kernel, which is more practical. The configuration parameter information is the information obtained by the command line interface tool after parsing the configuration command that meets the preset command line format, that is, the preset command line format is set in this application, and after the command line interface tool obtains the configuration command, if it meets the preset command line format, the configuration command is parsed to obtain the configuration parameter information. The disk array card performs corresponding configuration operations on the target attributes of the target business object based on the obtained target submission command, that is, this application is to realize the configuration management of the disk array card by constructing a target submission command through the command line interface tool to configure the attributes of a business object in the disk array card. In addition, after completing the configuration operation, the disk array card will send a target completion command based on the NVMe protocol. The target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol. After receiving the target completion command, the command line interface tool displays the attribute configuration result in the command line interface, thereby realizing the complete disk array card configuration process. In this way, the present application realizes the configuration management of the disk array card using the original management command of the NVME protocol under the command line interface tool.

[0144] It can be seen that the present application parses the obtained configuration command that meets the preset command line format through a preset command line interface tool to obtain configuration parameter information; uses the configuration parameter information to repackage the first target area of ​​the first original management command in the NVMe protocol to construct a target submission command; sends the target submission command to the disk array card, so that the disk array card performs corresponding configuration operations on the target attributes of the target business object based on the target submission command; obtains the target completion command constructed based on the NVMe protocol sent by the disk array card after completing the configuration operation, and displays the attribute configuration result in the command line interface; wherein the target completion command is a command obtained by repackaging the second target area of ​​the second original management command in the NVMe protocol.

[0145] Beneficial effects: A preset command line format is set in the present application. After the command line interface tool obtains the configuration command, if it satisfies the preset command line format, the configuration command is parsed to obtain the configuration parameter information. Further, the command line interface tool needs to use the configuration parameter information to construct a target submission command, specifically to re-encapsulate the first target area of ​​the first original management command in the NVMe protocol using the configuration parameter information, that is, the present application fills the configuration parameter information into the first target area of ​​the first original management command to realize the customization of the first original management command, and the present application adopts the mainstream NVMe protocol transmission in the storage field, the command transmission rate is faster, the NVME driver has been integrated in the mainstream operating system kernel, and it is more practical.
