Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

An optional application environment of the solution provided in the present disclosure is first described below, and fig. 1 is a schematic diagram of the application environment, including: the physical machine 001, the control device 002, and the storage device server 003, and the physical machine 001 is communicatively connected to the control device 002 and the storage device server 003, respectively.

Wherein physical machine 001 is a reference to a physical computer with respect to a virtual machine.

Alternatively, the storage device server 003 may be a server for managing storage devices. In particular, storage devices managed by storage device server 003 may be partitioned into a plurality of storage clusters, each of which may include at least one storage device therein. Each storage device may be a cloud hard disk, and storage device server 003 may also be referred to as a cloud server. The storage space of each storage device managed by the storage device server 003 may be the same or different. Alternatively, each storage device may be a block device. The block device has the characteristics of high performance and low time delay, supports random reading and writing, and can be used as a system disk or a data disk to be directly mounted on an example. Alternatively, each storage cluster may have a cluster identity and each block device may have a block identity. By means of the cluster identity and the block identity, one block device can be uniquely located. Alternatively, the physical machine may also have a unique identifier, which may be a device ID, such as an international mobile equipment identification (International Mobile Equipment Identity, IMEI) or a Serial Number (SN), and may also be an IP address (Internet Protocol Address) of the physical machine.

Alternatively, the control device 002 may be a separate device or may be composed of a plurality of different devices. The control device 002 may be deployed with a server application for managing the storage device, and the physical machine 001 may be installed with a client application for managing the storage device. The client application may communicate with the server application to complete the management of the storage device. The server application may probe the client application to determine if the client application is running. Of course, the client application may also probe the server application to determine whether the related service of the control device 002 can be used normally. As for the specific composition of the control device 002, the subsequent embodiments of the present disclosure will be described in detail.

Fig. 2 is a flowchart illustrating a storage device management method according to an exemplary embodiment, which is used in the physical machine 001 shown in fig. 1, as shown in fig. 1, and in which the physical machine 001 is communicatively connected to the control device 002 and the storage device server 003, respectively, as shown in fig. 2, and may include the following steps.

In step S11, the physical machine receives a storage device control instruction sent by a control instance of the control device, where the control device executes at least one control instance for acquiring and sending the storage device control instruction from the instruction queue, and the storage device control instruction in the instruction queue is generated by the control device and stored in the instruction queue.

Wherein, a control instance in the disclosure may be a service process, and when a plurality of control instances are executed in the control device, each control instance may be executed in parallel to increase a processing speed of a storage device control instruction in the instruction queue.

Alternatively, the storage device control instruction received by the physical machine may be a storage device mount instruction or a storage device offload instruction. The storage device mounting instruction may be used to instruct mounting the storage device on the physical machine, so that the physical machine and the storage device establish a data transmission channel. In this way, the physical machine can store data on the corresponding storage device. And the storage device unloading instruction is used for indicating to unload the storage device from the physical machine so as to release the data transmission channel of the physical machine and the storage device. In this way, the physical machine can no longer store data on the corresponding storage device.

Optionally, a plurality of storage device control instructions may be stored in the instruction queue, where each storage device control instruction may be acquired by each control instance in a first-in-first-out manner, and each control instance may acquire and process a storage device control instruction from the instruction queue. When the acquired storage device control instruction is a storage device mounting instruction or a storage device unloading instruction, the control instance sends the storage device mounting instruction or the storage device unloading instruction to the corresponding physical machine. Optionally, the storage device control instruction may carry an identifier of the instruction sender and an identifier of the instruction receiver, so that the control instance can know to which physical machine the storage device mount instruction or the storage device uninstall instruction needs to be sent through the identifier of the instruction receiver. Accordingly, by the identification of the instruction sender, the physical machine that receives the storage device control instruction can know which device sent the instruction.

Alternatively, after a control instance obtains a storage device control instruction from the instruction queue, the control instance may lock the storage device control instruction in the instruction queue to avoid other control instances from obtaining the storage device control instruction again. When a control instance determines that its transmitted storage device control instruction is complete (the storage device server completes management of the storage device based on the storage device management instruction), the control instance may delete the complete storage device control instruction from the instruction queue.

Wherein the control device can generate at least one storage device control instruction by means of the management interface. Specifically, the control device may generate at least one storage device control instruction according to the information transmitted from the management interface. Alternatively, the management interface may be an application interface or a web interface. Controls for entering storage device control information may be provided in the management interface, such as: input boxes, selection boxes, drop down lists, virtual keys, etc. The storage device control information may specifically include: device information of the storage device, identification of the physical machine, instruction type, and the like. Wherein, the device information of the storage device may include: the cluster identifier and the block identifier may be the control device to be controlled by locating the device information of the storage device. The identity of the physical machine may be an IP address of the physical machine. The instruction types may be: storage device mount instructions, storage device uninstall instructions, or storage device establish instructions, etc. The storage device setup instructions are to instruct setting at least one storage device to an available state for the target account, such as: when the target account selects two storage devices through the management interface and pays the use fee, the control device may generate a storage device setup instruction for instructing to set the two storage devices to the available states for the target account by means of the management interface.

The management interface may be displayed in a physical machine, a control device or other electronic devices, which is not limited in this disclosure. The control device may obtain various information input from the management interface and generate at least one storage device control instruction based on the information. Optionally, the management interface may have multiple sets of controls for inputting storage device control information, where each set of controls is used to input storage device control information for controlling one storage device. As shown in fig. 3, fig. 3 is a schematic diagram of a management interface according to an exemplary embodiment of the present disclosure, where the management interface includes multiple groups of controls, and four controls in a dashed box in fig. 3 are a group of controls, and are used to input storage device control information for controlling one storage device (block 0001 of cluster a). As can be seen from fig. 3, six sets of controls (one for each behavior) may be included in the management interface, and the management interface may simultaneously input storage device control information for controlling a plurality of storage devices, respectively. After the user finishes inputting, after clicking the 'confirm' button shown in figure 3, the control device can obtain the control information of the storage device input through a plurality of groups of controls.

The control device may generate a storage device control instruction according to storage device control information for controlling each storage device, and put the storage device control instruction into the instruction queue. For example: when the user inputs storage device control information for controlling six storage devices respectively at the management interface shown in fig. 3, the control device may generate six storage device control instructions.

The storage device management instruction may include: identification of the physical machine, instruction type, and device information of the storage device.

In step S12, the physical machine generates a storage device management instruction based on the storage device control instruction.

Alternatively, the physical machine may generate the storage device management instruction by changing the identification of the instruction sender and the identification of the instruction receiver in the storage device management instruction. For example: the physical machine modifies the identification of the instruction sender in the storage device management instruction into the identification of the physical machine, and simultaneously the physical machine modifies the identification of the instruction receiver in the storage device management instruction into the identification of the storage device server, so that the storage device management instruction is generated.

Of course, in addition to modifying the identifier of the instruction sender and the identifier of the instruction receiver, the physical machine may perform processing such as instruction format conversion to generate the storage device management instruction, which is not limited in this disclosure.

In an alternative embodiment of the present disclosure, step S12 may specifically include: the physical machine obtains the instruction type in the storage device control instruction and the device information of the first target storage device, and generates a storage device management instruction containing the identification of the physical machine, the instruction type and the device information of the first target storage device.

In step S13, the physical machine transmits a storage device management instruction to the storage device server, so that the storage device server manages the first target storage device based on the storage device management instruction.

Optionally, when the storage device management instruction is a storage device mounting instruction, the storage device server may establish a data transmission channel between the storage device indicated in the storage device mounting instruction and the physical machine. It should be noted that the data transmission channel may be a physical transmission channel or a software transmission channel.

In practical applications, at least the device state identifier of the first target storage device may be stored in the physical machine. The device state identification of the first target storage device may be: during mounting, mounted, unloaded, etc.

Optionally, after receiving a storage device mount instruction sent by a control instance of the control device, the physical machine may set a device state identifier of the first target storage device stored locally to be in mount. The physical machine may set the device state identifier of the first target storage device stored locally as being unloaded after receiving a storage device unloading instruction sent by the control instance of the control device.

In the storage device management method provided by the embodiment of the disclosure, a physical machine can receive a storage device control instruction sent by a control instance of a control device, the control device runs at least one control instance, each control instance obtains the storage device control instruction from an instruction queue to send, the control device generates at least one storage device control instruction, and the generated storage device control instruction is stored in the instruction queue; the physical machine generates a storage device management instruction based on the storage device control instruction; the physical machine sends a storage device management instruction to the storage device server, so that the storage device server manages the first target storage device based on the storage device management instruction. The method and the device can control the instruction through the storage equipment in the parallel execution instruction queue of a plurality of control examples, and effectively improve the processing speed of the instruction. Meanwhile, through the cooperation of the control equipment, the physical machine and the storage equipment server, the storage equipment can be mounted in the physical machine or unloaded from the physical machine, and a virtual machine is not required to be arranged on the physical machine at first, so that the method is simple and convenient.

The method shown in fig. 2 may further include:

When the storage device control instruction is a storage device mounting instruction and a storage device management result returned by the storage device server is that mounting is successful, the physical machine displays an icon of an access entrance of the first target storage device.

When the user clicks on the icon, the user may use the storage device through its access portal. Alternatively, the icon may be a system storage disk icon, such as: d disc, E disc, new roll F, etc., the present disclosure is not limited. Alternatively, the present disclosure may modify the device identification of a storage device mounted to a physical machine to include the IP address of the physical machine and the device identification of the drive letter of the storage device. For example: a storage device is mounted on a physical machine with an IP address of 10.10.2.3 and its drive letter is an E-disc, then the device identifier of the storage device may be modified as follows: as can be seen, the device identifier of the storage device modifies "." in the IP address to "_j", which can improve the security of the IP address.

Alternatively, the device identifier including the IP address of the physical machine and the drive letter of the storage device may be only the device identifier used by the storage device in the physical machine on which the storage device is mounted, or may be the device identifier used in the whole network. When the storage device is unloaded from the physical machine, the device identification of the storage device may be restored to a device identification including a cluster identification and a block identification.

The method shown in fig. 2 may further include:

and when the storage device control instruction is a storage device unloading instruction and the storage device management result returned by the storage device server obtained by the physical machine is that the unloading is successful, stopping displaying the icon of the access entrance of the first target storage device by the physical machine.

Optionally, when the physical machine obtains that the storage device management result returned by the storage device server is that the mounting is successful, the physical machine may set the device state identifier of the first target storage device stored locally as mounted. When the physical machine obtains the storage device management result returned by the storage device server and is successful in unloading, the physical machine can set the device state identifier of the first target storage device stored locally as unloaded.

Optionally, the disclosure may further save the device status identification of the at least one storage device through a database. In an alternative embodiment, only the device state identifiers of the storage devices related to the physical machine may be stored in one physical machine, and the database may store the device state identifiers of the storage devices.

Alternatively, the device state identifier stored in the database may be consistent with the device state identifier stored in each physical machine. In an alternative embodiment, each physical machine may set a device status identifier of the storage device associated therewith in a database. For example: the physical machine may set the device status identifier of the first target storage device in the database to be in the mount after receiving the storage device mount instruction sent by the control instance of the control device. The physical machine may set the device status identifier of the first target storage device in the database as being unloaded after receiving a storage device unloading instruction sent by the control instance of the control device. When the physical machine obtains the storage device management result returned by the storage device server and is that the mounting is successful, the physical machine can set the device state identifier of the first target storage device in the database as mounted. When the physical machine obtains the storage device management result returned by the storage device server and is successful in unloading, the physical machine can set the device state identifier of the first target storage device in the database to be unloaded.

Optionally, the physical machine sets a locally stored device state identifier and sets a sequence of device state identifiers stored in a database, which is not limited in this disclosure. For example: the physical machine may set the device state identifier of the first target storage device in the database to be in the mount after receiving the storage device mount instruction sent by the control instance of the control device, and then set the device state identifier of the first target storage device stored locally to be in the mount. When the physical machine obtains the storage device management result returned by the storage device server and is successful in mounting, the physical machine can set the device state identifier of the first target storage device stored locally as mounted, and then set the device state identifier of the first target storage device in the database as mounted.

Optionally, one physical machine may mount a plurality of storage devices, and the physical machine or other devices may store the correspondence between the physical machines with the mount relationship and the storage devices.

In an alternative embodiment, when the physical machine obtains that the storage device management result returned by the storage device server is that the mounting fails, the physical machine may alarm, for example: and alarming to an alarm system through a preset alarm mode (such as mail, short message, telephone and the like).

Optionally, the physical machine may further monitor the mounted storage device, where the monitored content may include: IO statistics of the storage device, storage amount/storage proportion of the storage device, whether the storage device is online or not, and the like.

FIG. 4 is a flowchart illustrating a method of storage device management, as shown in FIG. 4, according to an example embodiment, including:

The steps S11 to S13 are described in the embodiment shown in fig. 1, and are not repeated.

In step S14, the physical machine obtains a storage device management result returned from the storage device server.

In step S15, the physical machine sets a device status identifier of the first target storage device and/or sets a correspondence between the first target storage device and the physical machine according to the storage device management result.

When the storage device management result is that the mounting is successful, the physical machine can establish and store the corresponding relation between the first target storage device and the physical machine.

When the storage device management result is that the unloading is successful, the physical machine can delete the stored corresponding relation between the first target storage device and the physical machine.

in step S21, the control device generates at least one storage device control instruction, and stores the generated storage device control instruction in the instruction queue.

Optionally, the instruction type of the storage device control instruction generated by the control device may be: the storage device mounting instruction, the storage device unloading instruction, or the storage device establishing instruction are described in the embodiment shown in fig. 2, and are not described again.

Wherein the control device can generate at least one storage device control instruction by means of the management interface. Alternatively, the management interface may be the same as in the method shown in fig. 2. As shown in fig. 7, when storage device control information for creating one storage device (block 0003 of cluster a) needs to be input in a set of controls of the management interface, the information of the physical machine is not input, and the instruction type is set to "create", so that after clicking the "ok" button, the control device generates an instruction for creating the storage device of block 0003 of cluster a by means of the management interface, and stores the generated storage device creation instruction in the instruction queue.

The control device may generate a plurality of storage device control instructions by means of the management interface, and the instruction types of the respective storage device control instructions may be the same or different.

Alternatively, when the storage device control instruction is a storage device establishment instruction, the storage device establishment instruction may not include identification information of the storage device. Specifically, the storage device establishment instruction may include storage space information (for example, 1 gb), and the control device may select the storage device to establish according to the storage space information. For example: and selecting a storage device of one cluster according to the occupation condition of the cluster to establish.

Step S21 may specifically include:

the control device obtains the input multiple sets of storage device control information, generates a storage device control instruction according to each set of storage device control information, and stores the generated storage device control instruction into the instruction queue.

Alternatively, the multiple sets of storage device control information obtained by the control device may be entered through the management interface.

Optionally, after step S21, the method shown in fig. 5 may further include:

and the control equipment returns a preset response through the management interface.

After the control device stores the generated control instruction of the storage device into the instruction queue, the control device returns a preset response through the management interface and outputs corresponding information in time, so that the user is prevented from waiting for a long time. The preset response may be the word "processing, please be later", or may be voice, animation, etc. to inform the user that processing is occurring.

Of course, the above-described preset response may also be changed according to the instruction type, for example: when the instruction type is a storage device mount instruction, the preset response may be the word "mount, please be later.

In step S22, the control instance in the control device obtains the storage device control instruction from the instruction queue and sends the storage device control instruction to the physical machine related to the storage device control instruction, so that the physical machine generates a storage device management instruction based on the storage device control instruction and sends the storage device management instruction to the storage device server, and further, the storage device server manages the first target storage device based on the storage device management instruction.

Each control instance may fetch and process a storage device control instruction from the instruction queue. When the acquired storage device control instruction is a storage device mounting instruction or a storage device unloading instruction, the control instance sends the storage device mounting instruction or the storage device unloading instruction to the corresponding physical machine. Optionally, the storage device control instruction may carry an identifier of the instruction sender and an identifier of the instruction receiver, so that the control instance can know to which physical machine the storage device mount instruction or the storage device uninstall instruction needs to be sent through the identifier of the instruction receiver. Accordingly, by the identification of the instruction sender, the physical machine that receives the storage device control instruction can know which device sent the instruction.

The control instance in the control device can identify the identification of the instruction receiver of the acquired storage device control instruction, and send the identification to the corresponding instruction receiver according to the identification. When the identification of the instruction receiver is the identification of one physical machine, the control instance can send the storage device control instruction to the physical machine with the identification.

In the storage device management method provided by the embodiment of the disclosure, a control device generates at least one storage device control instruction, and stores the generated storage device control instruction into an instruction queue; the control instance in the control device obtains the storage device control instruction from the instruction queue and sends the storage device control instruction to the physical machine related to the storage device control instruction, so that the physical machine generates a storage device management instruction based on the storage device control instruction and sends the storage device management instruction to the storage device server, and further the storage device server manages the first target storage device based on the storage device management instruction. The method and the device can control the instruction through the storage equipment in the parallel execution instruction queue of a plurality of control examples, and effectively improve the processing speed of the instruction. Meanwhile, through the cooperation of the control equipment, the physical machine and the storage equipment server, the storage equipment can be mounted in the physical machine or unloaded from the physical machine, and a virtual machine is not required to be arranged on the physical machine at first, so that the method is simple and convenient. Meanwhile, the storage device can be created, and the flow for creating the storage device is simple and convenient.

Fig. 6 is a flowchart illustrating another storage device management method according to an exemplary embodiment, where the method shown in fig. 6 is applied to the control device 002 shown in fig. 1, and as shown in fig. 1, the control device 002 is communicatively connected to the storage device server 003, and the control device 002 operates at least one control instance, where the method shown in fig. 6 may include:

Step S21 shown in fig. 6 is the same as step S21 in the method shown in fig. 5, and will not be described again.

In step S23, the control instance in the control device obtains a storage device control instruction from the instruction queue, determines a second target storage device according to the obtained storage device establishment instruction when the obtained storage device control instruction is the storage device establishment instruction, and sets a device state identifier of the second target storage device as the first state identifier.

The first status identifier may be an identifier for indicating that the current status is in establishment, for example: "creating" or "establishing" and the like.

Alternatively, the control device may generate at least one storage device control instruction via the management interface.

The storage device establishment instruction carries identification information of the second target storage device to be established, so that the second target storage device can be determined through the identification information. By setting the device state identifier of the second target storage device as the first state identifier, other devices or accounts can be enabled to know the device state of the second target storage device, and collision is prevented. For example: after account a selects storage device 0001 of cluster a via the management interface and pays the usage fee, the control device may generate a storage device setup instruction via the management interface for instructing to set this storage device to the available status for account a. When a control instance obtains the instruction, the device state of storage device 0001 of cluster a may be identified as: the first state is identified. When other storage device management instructions need to manage the storage devices 0001 of the cluster a, the other storage device management instructions will not be able to manage the storage devices 0001 of the cluster a because the device state identifier of the storage devices 0001 of the cluster a is the first state identifier. At this time, the disclosure may inform relevant personnel to perform processing by outputting error reporting information, or may wait for the device status of the storage device 0001 of the cluster a to be identified as established, and then execute other storage device management instructions for managing the storage device 0001 of the cluster a.

In step S24, the control instance in the control device generates a storage device creation instruction based on the storage device creation instruction, and transmits the storage device creation instruction to the storage device server.

Alternatively, the control device may generate the storage device creation instruction by changing the identification of the instruction sender and the identification of the instruction receiver in the storage device creation instruction. For example: the control device modifies the identification of the instruction sender in the storage device establishment instruction to the identification of the control device, and the control device modifies the identification of the instruction receiver in the storage device establishment instruction to the identification of the storage device server, so that the storage device establishment instruction is generated.

Of course, in addition to modifying the identifier of the instruction sender and the identifier of the instruction receiver, the control device may perform processing such as instruction format conversion to generate the storage device creation instruction, which is not limited in this disclosure.

After the control device sends the storage device creation instruction to the storage device server, the storage device server can make the storage device setting available to the account a by setting the management authority possessor of the storage device as the account a, so that the creation of one storage device is realized. It should be noted that, in the creation of the storage device of the present disclosure, instead of establishing a new communication connection between the storage device and the storage device server, the management authority possessor of the storage device that has been in communication connection with the storage device server is set. For example: a storage device that has been communicatively connected to the storage device server has no management authority owner before, and after the account a is paid, the account a may be referred to as the management authority owner of the storage device, for which the disclosure "creates" a usable storage device, but the storage device exists before.

Optionally, the control device may also authenticate and manage the rights of each account. Specifically, when the key input by an account is a preset batch management key, the control device may control a management interface for performing batch management of the storage device to display, so as to generate a plurality of storage device management instructions by means of the management interface, so as to implement batch management of the storage device. When the key input by a certain account is not the preset batch management key, the control device can control the management interface for managing one storage device to be displayed, so that a storage device management instruction is generated by means of the management interface, and management of one storage device is realized.

The storage device server may send the creation result to the control device after completing creation of the storage device according to the storage device creation instruction. Of course, the control device may also query the storage device server periodically or aperiodically whether the storage device has been successfully created.

In step S25, the control device sets the device status identifier of the second target storage device to the second status identifier after determining that the creation of the second target storage device is successful.

Wherein, the second status identifier may be an identifier for indicating that the current status is established, such as: "created" or "established" and the like.

After setting the device state identifier of the second target storage device as the second state identifier, the control instance of the control device may execute a storage device mounting instruction for the second target storage device, so as to mount the established second target storage device on a physical machine. Thus, the physical machine can use the second target storage device, thereby realizing the expansion of the storage space.

Fig. 8 is an application environment diagram of a storage device management method according to an exemplary embodiment, and as shown in fig. 8, the control device 002 in fig. 1 may include: business logic layer 102, cluster management layer 104 and anomaly alarm system 106,

The cluster management layer 104 may be a middleware for managing the block storage clusters 103, and the cluster management layer 104 may obtain the cluster information of the block storage clusters 103 and send the cluster information to the block storage management interface 107 through the service logic layer 102 for display. Thus, the user can see each cluster included in the block storage cluster 103, and information such as the total storage capacity and free capacity of each cluster, through the block storage management interface 107. The accounts with rights may also control the clusters included in the block storage cluster 103 through the cluster management layer 104, for example: the total storage capacity of a cluster is adjusted. When the total storage capacity of a cluster is large, but the usage is low, the total storage capacity of the cluster can be reduced.

The block storage cluster 103 may include: a storage device server and a plurality of storage devices, each of which may be a block device. The storage device server may manage the block devices within the block storage cluster 103. The storage device server may be communicatively coupled to the control device, physical machine, etc. via the same or different application program interfaces (Application Programming Interface, API).

The cluster management layer 104 may also manage the image file, and the disclosure may store the image file in a storage device of the physical machine or mounted on the physical machine, so as to improve data security. The cluster management layer 104 may perform operations such as creating, copying, moving, deleting, etc. an image file.

The database 105 may store device status identifiers of the respective storage devices, and may store correspondence between physical machines and the storage devices. The correspondence may be specifically: correspondence between the IP address of the physical machine and cluster identification and block identification.

Alternatively, one physical machine may mount one or more storage devices, so the correspondence between the physical machine and the storage devices stored in the database 105 may be a correspondence between one physical machine and the plurality of storage devices, that is: one-to-many.

The anomaly alarm system 106 can scan the database 105 and can alarm in time when the data stored in the database 105 is found to be anomalous.

The monitoring platform 101 may monitor the physical machine 001, for example: monitor IO data of the physical machine 001, and the like. Optionally, an application program client of the monitoring platform 101 may be installed in the physical machine 001, so as to collect data in the physical machine 001 in time, thereby implementing monitoring.

Alternatively, the monitoring platform 101 may be an integral part of the control device, or may be a separately provided device, which is not limited in this disclosure.

Business logic layer 102 may also be in communication with third party platform 108 such that third party platform 108 may implement management of storage devices through business logic layer 102, for example: the device resource management platform of a company is in butt joint with the business logic layer 102, and the platform can mount the storage devices in the block storage cluster 103 to the physical machine 001 of the company for use through the business logic layer 102. Alternatively, business logic layer 102 may communicate with third party platform 108 through an application program interface API.

Business logic layer 102 may also perform data persistence operations such as: and performing persistence operation on the storage device control instruction. Business logic layer 102 may save each storage device control instruction in the instruction queue to a persistent disk so that the instruction queue is not lost even if power is lost. After the power is on again, the instruction queue stored before can be obtained from the persistent disk, and the control instruction of the storage device in the instruction queue can be continuously processed. Optionally, the present disclosure may store the locking state of each storage device control instruction at the same time, so that after powering on again, the control instance may determine, according to the locking state, whether the storage device control instruction has control instance processing and which control instance reprocesses, thereby avoiding repeated execution.

Alternatively, business logic layer 102 may perform persistence operations on all data it receives, processes, and transmits.
