Conventional RAID cards are PCIe (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, high speed serial computer expansion bus standard) devices on a computer system, with the RAID cards being connected to the computer system host through a PCIe bus.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The conventional RAID card is PCIe device on the Computer system, is connected to the host through a PCIe bus, and uses a SCSI (Small Computer SYSTEM INTERFACE ) or NVMe (Non-Volatile Memory express, non-volatile memory host controller interface specification) interface to perform command interaction on a configuration interface of an upper layer service, so as to achieve acquisition and issue of configuration data between the configuration interface and the RAID card. The configuration interface and RAID card data interaction adopts a serial request response mode, and the interaction logic is as follows: when a user operates the configuration interface, the package command acquires data to be displayed from the RAID card side by triggering the background action of the interface, then the data is displayed on the configuration interface, the user issues configuration information according to the data displayed on the interface, the background is triggered to issue the configuration command to the RAID card side, and the RAID card side returns the execution result of the configuration command and displays the configuration command on the configuration interface. In configuring a volume, it is necessary to obtain information of the disk and the array in the RAID card. Since the mainstream RAID card supports hundreds of disks, arrays and volumes, the configuration interface needs to display more content, and a great deal of time is required to query the RAID card side. Therefore, when a large amount of data information of the service module needs to be displayed on the configuration interface, the interactive logic can only continuously request the response message to obtain the data through the background, which can consume a long time, so that the configuration interface often has a clamping phenomenon when the user operates. In addition, in the process of acquiring the data on the RAID card side through the serial request response mode, a scene of inconsistent data can occur, so that the data displayed on the interface is inaccurate.

The main functions of the configuration interface of the host include: viewing and configuration of information for RAID card Controllers (CTRL), disks (disks), ARRAYs (ARRAY), and volumes (Volume). The data viewed and configured through the configuration interface includes: RAID card resource data (physical information, capacity, etc.) and configuration data (constituting an array). The resource data includes: the information such as the controller version number, the controller serial number, the controller status, etc., and also includes information such as the ID (Identity document, unique code) of the disc, the capacity of the disc, the status of the disc, etc. The configuration data includes: RAID array information created by a user and logic volume information created by the user.

The interaction logic of the host configuration interface with the RAID card is described in connection with FIG. 1. And RIAD, a card information viewing function, namely, inquiring the required data from the RAID card side according to a defined protocol by the host according to an inquiry object defined by the interface. Fig. 1 is a schematic diagram of a configuration interface data acquisition and configuration channel, before displaying data, a configuration interface at a host side sends a data request to a first configuration Module (Config Module), the first configuration Module encapsulates a command according to an interface background operation object, calls a related driving interface, sends the command to an access Module of a chip firmware at a RAID card side through a Bus (for example, driver Bus Layer), after receiving a command defined by the host, the access Module analyzes the command type and forwards the command to a second configuration Module of the board firmware, the board firmware sequentially sends information required for collecting internal messages to each service Module (controller CTRL, disk, ARRAY, volume, etc.) according to a protocol analysis command, each service Module collects information in and related to the Module according to the sent command, then returns a response message to the second configuration Module, assembles all acquired information to the chip firmware at the board firmware, finally returns the returned information through the Bus (Driver Bus Layer), and the first configuration Module of the host assembles the returned data to the host according to a certain logic requirement and displays the returned information to the interface. The configuration interface is aimed at the configuration function of the RAID card, and mainly comprises that a host firstly inquires relevant display information from the RIAD cards according to the configuration object and displays the information to the interface, then a user configures the required function according to the display information of the interface, a background of the host is triggered to send a configuration command to the RAID card, and the RAID card receives the command to execute the configuration action.

The embodiment of the invention provides a RAID card configuration information management method, which comprises the steps of deploying a first data center in a first configuration module of a host side, storing configuration information of each service module of a RAID card into the first data center in advance, and directly acquiring the configuration information from the first data center when a configuration interface needs to display data, so that the required data does not need to be queried to the RAID card side. After the user issues the configuration command through the configuration interface, the configuration command is only required to be issued to the RAID card side, so that the interaction times between the host side and the RAID card side are reduced. The method and the device have the advantages that the information of the RAID card is accurately displayed on the configuration interface in real time, and the RAID card is accurately configured and managed in real time.

According to an embodiment of the present invention, there is provided a RAID card configuration information management method embodiment, it should be noted that the steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order other than that shown or described herein.

In this embodiment, a method for managing configuration information of a RAID card is provided, which is applicable to a storage device that needs to perform RAID configuration management, for example, a server related to RAID, etc. Fig. 2 is a flowchart of a RAID card configuration information management method according to an embodiment of the present invention, the method being applied to a host, as shown in fig. 2, the flowchart including the following steps.

Step S201, obtaining configuration information of the RAID card from the RAID card, and storing the configuration information in a first data center of the host.

Specifically, a first data center is deployed at a first configuration module of the host side, where the first data center is a database, and is used to store configuration information of each service module of the RAID card side, and the service modules are for example: controllers, physical disks, arrays, logical volumes, etc., configuration information such as: controller version number, number of controllers, array identifier, array stripe size, volume name, volume capacity, disk identifier, disk capacity, etc. It should be noted that, the configuration information includes not only information actively configured by the user, for example: the configuration information also includes attribute information inherent to each service module itself, which does not need to be configured by a user, for example: the version number of the controller, the serial number, the firmware version of the disk, the serial number, etc.

The first configuration module of the host side sequentially acquires configuration information of each service module in the RAID card from the RAID card, and stores the configuration information to the first data center.

Step S202, a data request of a configuration interface is obtained.

Specifically, the configuration interface main functions include: viewing and configuring business module information. When a user views service module information through a configuration interface, the configuration interface sends a data request to a first configuration module of a host side, for example: when a user configures the RAID card volume, the configuration interface needs to display the configuration information of the volume name, volume, state, affiliated array, disk and the like, generates a data request corresponding to the configuration information, and sends the data request to the first configuration module.

Step S203, according to the data request, the target data is obtained from the first data center and sent to the configuration interface, wherein the target data is contained in the configuration information.

Specifically, since the first data center of the first configuration module at the host side stores the configuration information of each service module at the RAID card side, after receiving a data request, the first configuration module may acquire target data required by the data request from the first data center, and send the target data to the configuration interface, and the configuration interface displays the target data. As shown in fig. 3, after the user opens the interface, the RAID card configuration interface triggers the background query interface to display data, and sends the data to the host configuration data center (i.e. the first data center), where the host configuration data center returns the queried data to the RAID card configuration interface. And the RAID card configuration interface displays the data interface back.

According to the RAID card configuration information management method, configuration information of the RAID card is stored in the first data center, when a data request of the configuration interface is acquired, target data can be acquired from the first data center, so that the configuration interface can quickly acquire required target data and timely display the required target data, a host does not need to frequently search the configuration information from the RAID card, interaction times of the host and the RAID card in the configuration process are reduced, the configuration interface is prevented from being blocked, and smoothness and convenience of the configuration interface are improved. The method solves the problem that the configuration interface cannot timely display configuration information required by the configuration of the RAID card when the configuration interface is used for configuring the RAID card.

In this embodiment, another method for managing configuration information of a RAID card is provided, which is applicable to a storage device that needs to perform RAID configuration management, for example, a server related to RAID, etc. Fig. 4 is a flowchart of a RAID card configuration information management method according to an embodiment of the present invention, the method being applied to a host, as shown in fig. 4, the flowchart including the following steps.

Step S401, configuration information of the RAID card is obtained from the RAID card, and the configuration information is stored in a first data center of a host.

Specifically, step S401 "the first data center that acquires the configuration information of the RAID card from the RAID card and stores the configuration information to the host computer" includes the following steps S4011 to S4014.

Step S4011, a first data request message is sent to the RAID card, where the first data request message is used to obtain configuration information of a preset number of service modules in the RAID card.

Step S4012, obtain a first response message corresponding to the first data request message, where the first response message is generated by the RAID card according to the configuration information after receiving the first data request message.

Step S4013, parse the first response message to obtain the configuration information.

Step S4014 stores the configuration information to the first data center.

As shown in fig. 5, after the first configuration module is started successfully, the first configuration module sequentially sends a data table request message to the second configuration module, where the data table request message is the first data request message. The second configuration module sequentially acquires the total information of the tables from the second database, the total information of the tables is configuration information, the data of the data tables are responded to the first configuration module, and the first configuration module stores the data of the tables to the first data center.

After receiving the first response message, the host analyzes the first response message to obtain configuration information, and stores the configuration information to the first data center. The host acquires all the configuration information required by the RAID card side through the method and stores the configuration information in a first data center of the host.

Therefore, the scheme of combining the active request response mechanism and the asynchronous monitoring response mechanism is adopted in the invention to realize the real-time synchronization of the data of the second data center to the first data center.

Specifically, in order to facilitate obtaining configuration information of the service module, the configuration information is divided into a plurality of data items to be monitored in detail according to factors such as service performance, and the data items to be monitored include: version number, serial number, maximum number of disks, background task, etc. of the controller; an identifier of the array, a stripe size, a remaining capacity, a task status, etc.; the name, capacity, etc. of the volume; disc identifier, firmware version, etc.

Asynchronous monitoring events of the data items to be monitored are generated, and each asynchronous monitoring event is used for monitoring whether the data of the corresponding data item to be monitored is changed, such as adding, modifying, deleting and the like. These asynchronous monitoring events are issued in turn to the card firmware of the RAID card. After receiving the asynchronous monitoring event, the board card firmware feeds back a feedback message of successful monitoring to the host. After the host acquires the feedback information corresponding to the asynchronous monitoring event from the RAID card, the successful issuing of the asynchronous monitoring event can be determined, otherwise, the issuing of the asynchronous monitoring event fails and needs to be issued again. The above process is shown in fig. 5: the first configuration module sequentially sends asynchronous event monitoring information of the data table to the second configuration module, and the second configuration module feeds back a monitoring success response message to the first configuration module.

If the data of the data item to be monitored in the configuration information of the service module in the RAID card is changed, such as adding, modifying, deleting and the like, a corresponding asynchronous monitoring event is triggered, and the change configuration information of the data item to be monitored is notified to the host asynchronously. Or under the condition that the second data center is created by the second configuration module, if the configuration information stored in the second data center changes, the change configuration information of the data item to be monitored in the configuration information is notified to the host asynchronously.

Since the RAID card has a plurality of disks, arrays, and volumes, the number of the three tables is defined according to the RAID card product specification, and there is only one controller in the RAID card, so the number of the controller tables is one. Each attribute in each table represents a property of the corresponding object. In addition, more detailed table entry division can be performed according to actual requirements, and other RAID card data tables and other first preset RAID card data table entries can be generated.

Specifically, a first configuration module of the host obtains the first preset RAID card data entry.

In this embodiment, described with reference to fig. 3, after the service module receives a configuration command issued by the host, the service module executes the configuration command, and generates service configuration information after the command is configured successfully, where data in the table changes. The service module pushes the data of the change table, namely service configuration information, to a second data center of the board card firmware, the data in the second data center data table changes, the data of the change table is sent to a first data center of the host, and the first data center updates the data of the corresponding table.

Specifically, a service module in the RAID card executes a configuration command to generate service configuration information. If the newly generated service configuration information causes the data of the data item to be monitored in the service module configuration information to be changed, such as adding, modifying, deleting and the like, a corresponding asynchronous monitoring event is triggered. And the service module encapsulates the service configuration information into a second response message and sends the second response message to the host.

After the host acquires the second response message from the RAID card, the second response message is analyzed to obtain service configuration information. And the host updates the configuration information of the first data center according to the service configuration information.

In order to ensure that the data of the first data center has accuracy and instantaneity, the first configuration module is designed to acquire the configuration information of all the service modules from the board card firmware at regular time, compare the configuration information with the data stored in the first data center, and update the data of the first data center if the configuration information is inconsistent with the data stored in the first data center.

Specifically, the first preset time is, for example: 3 am every night. At a first preset moment, a first configuration module of the host sends a first full-volume data request message to the RAID card, and the first full-volume data of the service module in the RAID card is obtained through the first full-volume data request message, wherein the first full-volume data contains all configuration information of the service module. After the second configuration module of the RAID card board card firmware receives the first full data request message, the second configuration module packages the first full data into a third response message after acquiring the first full data from the second data center or all service modules, and sends the third response message to the host.

The host acquires a third response message from the RAID card, and analyzes the third response message to obtain the first full data. And comparing the first full-volume data with the data of the first data center, and if the first data center has data inconsistent with the first full-volume data, updating the inconsistent data according to the first full-volume data.

In some alternative embodiments, the step S8014 "storing the configuration information to the second data center" includes the following steps J1 to J3.

Step J1, determining a data field of at least one third operation object in the configuration information; the data field of the third operation object comprises at least one of an object type field, an object name field and an object attribute field of the third operation object;

Step J2, determining third index information corresponding to the data field of a third operation object according to a preset second mapping relation; the second mapping relation comprises a mapping relation between data fields and indexes of a third operation object, and the third index information comprises at least one of a third object type index, a third object name index and a third object attribute index corresponding to the third operation object;

And step J3, generating a second data structure tree according to the third index information and the values of the corresponding data fields according to the hierarchical sequence of the object type, the object name and the object attribute, and storing the second data structure tree into a second data center.

In the present embodiment, text representing the operation object type is regarded as an object type field, for example: the physical disk is an object type field and the logical volume is an object type field. Regarding the operation object name as an object name field, for example: a disk is an object name field and array B is an object name field. Regarding the above-described attributes as object attribute fields, for example: the cache policy is an object attribute field and the stripe size is an object attribute field.

And integrating the corresponding relation between the object type field and the type index, the corresponding relation between the object name field and the name index and the corresponding relation between the object attribute field and the attribute index to obtain a preset second mapping relation.

The preset second mapping relationship and the first mapping relationship should be kept consistent, if the user modifies the first mapping relationship, the modified first mapping relationship needs to be synchronized to the RAID card in time.

Specifically, during the process of storing the configuration information in the second data center, the RAID card first determines a data field of at least one third operation object in the configuration information, where the third operation object is for example: a controller, an array, a logical volume, and a physical disk; the data field of the third operation object includes at least one of an object type field, an object name field, and an object attribute field of the third operation object, the object type field being, for example: controllers, arrays, logical volumes, physical disks, object name fields such as: controller, A disk, array B, logical volume C, object attribute fields such as: version number, firmware version, stripe size, cache policy.

And determining a third object type index corresponding to the object type field, a third object name index corresponding to the object name field and a third object attribute index corresponding to the object attribute field according to the preset second mapping relation, wherein the third index information comprises at least one of the third object type index, the third object name index and the third object attribute index.

And generating a second data structure tree according to the third index information and the values of the corresponding data fields according to the hierarchical sequence of the object type, the object name and the object attribute, and storing the second data structure tree into a second data center. For example: constructing a first-layer structure tree node in the second data structure tree according to the type index, wherein the first-layer structure tree node is used for storing common configuration information of each operation object type; constructing a second-layer structure tree node serving as a child node of the first-layer structure tree node according to the name index, and storing configuration information of each operation object; and constructing a third-layer structure tree node serving as a child node of the second-layer structure tree node according to the attribute index, wherein the third-layer structure tree node is used for storing each attribute of the operation object and is also a child node corresponding to the first-layer structure tree node.

In some alternative embodiments, the step I1 "obtaining the configuration information of the service module from the second data center" includes the following steps K1 to K2.

Step K1, analyzing the first data request message to obtain first index information; the first index information comprises at least one of a first object type index, a first object name index and a first object attribute index corresponding to the first operation object;

and step K2, inquiring and obtaining configuration information required by the host in the second data structure tree according to the first index information.

Specifically, the first data request message includes the first index information, so the RAID card parses the first data request message to obtain the first index information. The first index information comprises at least one of a first object type index, a first object name index and a first object attribute index corresponding to the first operation object.

If the first index information contains the first object type index, the first object name index and the first object attribute index, the RAID card queries step by step in the second data structure tree according to the first index information, determines a corresponding fourth target node, and takes configuration information corresponding to the fourth target node as configuration information required by the host.

If the first index information only comprises the first object type index and the first object name index, the RAID card determines a corresponding fifth target node in the second level nodes of the second data structure tree according to the first index information, and takes the configuration information corresponding to the fifth target node and all or part of sub-nodes of the fifth target node as configuration information required by the host.

If the first index information only contains the first object type index, the RAID card determines a sixth target node in the first level nodes of the second data structure tree according to the first object type index, and takes configuration information corresponding to all or part of sub-nodes of the sixth target node and the sixth target node as configuration information required by the host.

In some alternative embodiments, the step I2 "generating the first response message according to the configuration information of the preset number of service modules" includes the following steps L1 to L2.

Step L1, constructing a target data structure tree containing configuration information required by a host according to the hierarchical sequence of the object type, the object name and the object attribute and the first index information;

And step L2, packaging the target data structure tree layer by utilizing a preset data packaging format, and generating a first response message.

Specifically, after receiving the first data request message including the first index information, the RAID card determines configuration information required by the host according to the first index information, constructs a target data structure tree including the configuration information required by the host according to the first index information according to the hierarchical sequence of the object type, the object name, and the object attribute, and may write the first index information into a corresponding node in the target data structure tree. Performing layer-by-layer encapsulation by using a target data structure tree with a preset data encapsulation format, and generating a first response message, wherein the preset data encapsulation format is as follows: the json mode data package format uses typeid, objectid and tagid of each operation object as keys, and the corresponding configuration information data as values.

In some alternative embodiments, after the above step S8014 "store configuration information to the second data center", the following steps M1 to M3 may be further included.

And M1, acquiring a second preset RAID card data table entry, wherein the second preset RAID card data table entry is used for dividing configuration information.

And M2, generating subscription messages corresponding to each second preset RAID card data table item, wherein the subscription messages are used for acquiring change configuration information from the service module.

And M3, sending the subscription information to the service module, and acquiring a subscription success feedback information from the service module.

In this embodiment, a mechanism combining request response and subscription publishing is adopted between the second configuration module of the board card firmware and each service module to realize data communication.

Specifically, the second configuration module obtains a second preset RAID card data entry, where the second preset RAID card data entry is obtained by dividing configuration information, and the second preset RAID card data entry may be consistent with the first preset RAID card data entry, so as to facilitate synchronization of data of the second data center to the first data center, as shown in fig. 6. The second preset RAID card data entry may also be inconsistent with the first preset RAID card data entry, but a mapping relationship between the second preset RAID card data entry and the first preset RAID card data entry needs to be created in advance, so that data synchronization is convenient.

The second configuration module generates a subscription message corresponding to each second preset RAID card data table item, and monitors whether the data of the corresponding second preset RAID card data table item is changed or not by using a subscription pushing mechanism. The second configuration module sends the subscription message to the service module. After the second configuration module obtains the subscription success feedback message from the service module, the second configuration module can determine that the subscription message is successfully issued, otherwise, the subscription message is failed to be issued and needs to be issued again. The above process is shown in fig. 9, where the second configuration module sends a subscription message corresponding to the service module data table to the service module. The service module returns a subscription success response message.

In some optional embodiments, after the foregoing step M3 "send subscription message to service module and acquire subscription success feedback message from service module", the following steps N1 to N3 may be further included.

And step N1, obtaining a push message from the service module, wherein the push message is a message containing changed configuration information generated when the information of the table item corresponding to the subscription message received by the service module is changed.

And step N2, updating the corresponding data in the second data center according to the changed configuration information.

And step N3, triggering an asynchronous monitoring event and sending the changed configuration information to the host, wherein the asynchronous monitoring event is issued to the RAID card by the host and is used for monitoring whether the configuration information on the RAID card side is changed or not.

In this embodiment, a subscription pushing mechanism is already established between the second configuration module and the service module, and when the configuration information of the service module changes, the service module pushes the changed configuration information to the second configuration module.

Specifically, when the configuration information of the service module changes, for example: and adding, modifying, deleting and the like, wherein the service module generates push information according to the change configuration information of the table item corresponding to the subscription information and sends the push information to the second configuration module of the RAID card.

The second configuration module acquires the push message from the service module, and updates the data corresponding to the second data center according to the changed configuration information in the push message. In the above process, as shown in fig. 9, when the data in the service data table of the service module changes, the service module pushes the change data to the second configuration module, and the second configuration module updates the data in the second data center. In addition, after the update of the second data center is completed, the data of the second data center changes, and the second configuration module triggers an asynchronous monitoring event issued by the host and asynchronously sends the changed configuration information to the host.

In some optional embodiments, the method for managing RAID card configuration information may further include the following steps O1 to O2.

And step O1, acquiring the first full data of the second data center under the condition that the first full data request message is received.

And step O2, generating a third response message according to the first full data, and sending the third response message to the host.

In this embodiment, in order to ensure that the data of the first data center has accuracy and real-time performance, the first configuration module is designed to acquire the configuration information of all the service modules from the board firmware at regular time, compare the configuration information with the data stored in the first data center, and update the data of the first data center if the configuration information is inconsistent with the data stored in the first data center.

Specifically, the first configuration module of the host sends a first full-volume data request message to the RAID card at a first preset time.

And under the condition that the RAID card receives the first full data request message, acquiring all data in the second data center, namely the first full data, packaging the first full data into a third response message, and sending the third response message to the host.

In some alternative embodiments, after the above step S8014 "store configuration information to the second data center", the following steps P1 to P4 may be further included.

And step P1, at a second preset time, sending a second full-volume data request message to a preset number of service modules, wherein the second full-volume data request message is used for acquiring the second full-volume data of the service modules, and the second preset time is earlier than the time when the first full-volume data request message is received.

And step P2, acquiring a fifth response message from the service module, wherein the fifth response message contains the second full amount of data.

And step P3, comparing the second full data with the data of the second data center, and if the second data center has difference data, updating the difference data according to the second full data to obtain updated difference data.

And step P4, triggering an asynchronous monitoring event, and sending the updated difference data to the host, wherein the asynchronous monitoring event is issued to the RAID card by the host and is used for monitoring whether the configuration information of the RAID card side is changed or not.

In this embodiment, the present embodiment is used to perform consistency checking on the second data center and each service module data. In order to ensure the reliability of the second data center, the second configuration module is designed to periodically obtain all configuration information of each service module, compare the configuration information with the data of the second data center according to all configuration information, and update inconsistent data in the second data center.

Specifically, the second preset time is, for example: at 2 a.m. each night, the second preset time is earlier than the time when the first full data request message is received (i.e. the first preset time). And the second configuration module of the RAID card sends a second full-quantity data request message to a preset number of service modules at a second preset moment to acquire all configuration information (namely second full-quantity data) of the service modules.

And after receiving the second full-volume data request message, the service module encapsulates the second full-volume data into a fifth response message and returns the fifth response message to the second configuration module.

The second configuration module analyzes the fifth response message to obtain second full data, compares the second full data with the data of the second data center, and if the second data center has difference data, updates the difference data of the second data center according to the second full data to obtain updated difference data.

Because the data of the second data center is modified, an asynchronous monitoring event issued by the host is triggered, and the updated difference data is asynchronously sent to the host, so that the data synchronization between the second database and the first database is completed.
