Referring to FIG. 2, the embodiment of the present application provides a method for storing data, which may be applied to the system shown in FIG. 1 , and the execution of the method may be a server in the system, including:

Step 201: Receive a storage command sent by the terminal by using a connection corresponding to the first virtual file, where the storage command includes a data to be stored and a starting address of the data to be stored in the first virtual disk.

Exemplarily, the first virtual file is a virtual file in the server, and the first virtual disk is a virtual disk corresponding to the first virtual file in the terminal, and the connection is a connection between the terminal and the server.

Step 202: Determine, according to the start address and the first virtual file, an offset address of the first storage block unit and the data to be stored in the first storage block unit.

Exemplarily, the first virtual disk corresponds to at least one storage block unit in the cloud storage platform, and the first storage block unit is one of the at least one storage block unit.

Step 203: Store the data to be stored in the first storage block unit according to the offset address.

Referring to FIG. 3, an embodiment of the present application provides a method for storing data, which may be applied to the system shown in FIG. 1, including:

Step 301: The terminal creates a second virtual disk, establishes a connection corresponding to the second virtual disk with the server, and sends a create command to the server, where the create command includes the capacity of the second virtual disk.

The user can trigger the terminal to create a second virtual disk and set the capacity of the second virtual disk in the terminal. The terminal can obtain the capacity of the second virtual disk set by the user, create a second virtual disk, establish a connection corresponding to the second virtual disk with the server, and send a create command to the server through the connection, the creation command includes the second The capacity of the virtual disk.

The second virtual disk created by the terminal is not the physical disk actually existing on the terminal. Therefore, in this embodiment, the terminal may not include a disk.

Step 302: The server receives the creation command, creates a second virtual file corresponding to the second virtual disk, and sets a second virtual file corresponding to the connection.

The server can receive the creation command through the connection, create a virtual kernel device corresponding to the second virtual disk at the kernel layer thereof, and create a virtual user device corresponding to the second virtual disk and the second virtual file at the user layer thereof, and associate the connection with the virtual device. The virtual kernel device associates the virtual kernel device with the virtual user device and associates the virtual user device with the second virtual file.

Exemplarily, the operating system installed by the server may be a Linux system, and the virtual kernel device and the virtual user device may be created by using the provided targetcli command. The virtual kernel device can be used as a lun device, and the lun device is a block device, and the virtual user device acts as a UIO device.

The second virtual file created by the server is not the file actually existing on the server. In the server, only the file identifier of the second virtual file can be used as the second virtual file. In this embodiment, the disk may not be included in the server.

Step 303: The server applies for at least one storage block unit corresponding to the second virtual disk in the cloud storage platform according to the capacity of the second virtual disk.

The cloud storage platform includes a metadata cluster and a storage cluster. The storage cluster includes a large number of storage block units, and each storage block unit has the same capacity.

Exemplarily, the memory block unit can be an object.

The method may be: the server calculates the number of the storage block units corresponding to the second virtual disk according to the capacity of the second virtual disk and the capacity of the storage block unit, and applies the storage block unit from the storage cluster of the cloud storage platform according to the number. The applied storage block unit is a storage block unit corresponding to the second virtual disk.

For example, assuming that the capacity of the second virtual disk is 30G, the capacity of each storage block unit in the storage cluster of the cloud storage platform is 5G, so that the second is calculated according to the capacity 30G of the second virtual disk and the capacity 5G of the storage block unit. The number of the storage block units corresponding to the virtual disk is six, and six storage block units are applied from the storage cluster of the cloud storage platform, and the six storage block units are the storage block units corresponding to the second virtual disk.

Step 304: The server saves the file identifier of the second virtual file and the unit identifier of each storage block unit corresponding to the second virtual disk in the corresponding relationship between the file identifier and the unit identifier of the cloud storage platform.

The metadata cluster of the cloud storage platform stores the correspondence between the file identifier and the unit identifier. Therefore, in this step, the server may save the file identifier of the second virtual file and the unit identifier of each storage block unit corresponding to the second virtual disk in the correspondence between the file identifier and the unit identifier in the metadata cluster.

Exemplarily, the steps of 301 to 304 above may be repeatedly performed, creating a plurality of virtual disks on the terminal and creating a virtual file corresponding to each virtual disk at the server.

After one or more virtual disks are created on the terminal, the user can store data to a virtual disk of the terminal. For convenience of description, the virtual disk is called the first virtual disk, and the data is called data to be stored. Then store the data to be stored in the first virtual disk as follows.

Step 305: The terminal acquires a starting address of the data to be stored and the data to be stored in the first virtual disk, and sends a storage command to the server by using a connection corresponding to the first virtual disk, where the storage command includes data to be stored and the starting address.

Exemplarily, the user may input the data to be stored to the terminal, and may also input the starting address of the data to be stored in the first virtual disk to the terminal. Alternatively, the terminal may save the occupied space capacity of the first virtual disk. When receiving the data to be stored that needs to be stored in the first virtual disk, the data to be stored may be determined according to the occupied space capacity. The starting address in the first virtual disk.

Step 306: The server receives, by using the connection, a storage command sent by the terminal, where the storage command includes a data to be stored and a starting address of the data to be stored in the first virtual disk, and determines a first virtual file corresponding to the connection.

Exemplarily, the first virtual file is a virtual file corresponding to the first virtual disk in the server. And the first virtual file has a corresponding file identifier.

Illustratively, the server receives the storage command via a virtual kernel device associated with the connection, the virtual kernel device entering the storage command into the virtual user device. The server then retrieves the storage command from the virtual user device.

Exemplarily, the command sent by the terminal to the server is first received by the virtual kernel device of the kernel layer, and the server does not know whether the command is a read command or a storage command. The virtual core device enters the command into its corresponding virtual user device. At the user layer, the server can obtain the command from the virtual user device, and identify whether the command is a read command or a storage command, and obtain a virtual file corresponding to the virtual user device as the first virtual file.

Step 307: The server determines, according to the start address and the first virtual file, an offset address of the first storage block unit and the data to be stored in the first storage block unit.

Specifically, the server acquires, according to the file identifier of the first virtual file, the at least one unit identifier corresponding to the first virtual disk from the correspondence between the file identifier and the unit identifier stored by the cloud storage platform; according to the start address and the storage block unit The capacity determines an offset address of the first memory block unit and the data to be stored in the first memory block unit from the memory block unit corresponding to each unit identifier.

Exemplarily, the capacity of each memory block unit in the cloud storage platform may be equal. It is assumed that the starting address of the data to be stored in the first virtual disk is at the position of 7G, and the capacity of each storage block unit is 5G. Thus, according to the start address and the capacity of the storage block unit, the determined first storage block unit is the second storage block unit corresponding to the first virtual disk and the offset address of the data to be stored in the first storage block unit is 2G. s position.

Step 308: The server stores the data to be stored in the first storage block unit according to the offset address.

For example, the server may store the data to be stored in the second storage block unit corresponding to the first virtual disk according to the location of the 2G.

In the embodiment of the present application, since the virtual kernel device, the virtual user device, and the virtual file corresponding to the virtual disk of the terminal are created in the server, when the data to be stored is stored on the first virtual disk of the terminal, the server passes the first The virtual kernel device corresponding to the virtual disk receives the storage command, and the virtual kernel device inputs the storage command to the corresponding virtual user device, and the server obtains the storage command from the virtual user device, according to the first virtual file corresponding to the virtual user device. Determining, in the storage command, a first storage block unit for storing data to be stored in the cloud storage platform and an offset address of the data to be stored in the first storage block unit, according to the offset address, The data to be stored is stored in the first memory block unit. In this way, the data to be stored is stored in the cloud storage platform, and the reliability of the storage data of the cloud storage platform is high, thereby improving the reliability of the data storage.

Referring to FIG. 4, the embodiment of the present application provides a method for reading data, which may be applied to the system shown in FIG. 1 , and the execution of the method may be a server in the system, including:

Step 401: The read command sent by the terminal is received by the connection corresponding to the first virtual file, where the read command includes the data amount of the data to be read and the start address of the data to be read in the first virtual disk.

Step 402: Determine an offset address of the first memory block unit and the data to be read in the first memory block unit according to the start address and the first virtual file.

Step 403: Read data to be read from the first storage block unit according to the offset address and the data amount.

Step 404: Send data to be read to the terminal.

In the example of the present application, since the first virtual file corresponds to the connection of the terminal, after receiving the read command of the terminal through the connection, determining the cloud storage according to the first virtual file and the starting address in the read command And a offset address of the first memory block unit for storing data to be read and the data to be read in the first memory block unit in the platform, and reading data in the first memory block unit according to the offset address. This can support the storage of data in the cloud storage platform, and the storage reliability of the cloud storage platform is higher, thereby improving the reliability of the data storage.

Referring to FIG. 5, an embodiment of the present application provides a method for reading data, which may be applied to the system shown in FIG. 1, including:

Steps 501 to 504 are the same as steps 301 to 304, respectively, and will not be described in detail herein.

Exemplarily, when the user needs data in the first virtual disk, the user may input the starting address of the data to be read in the first virtual disk and the data amount of the data to be read to the terminal, where the first virtual disk is a terminal. Any of the virtual disks in .

Step 505: The terminal acquires a starting address of the data to be read in the first virtual disk and a data amount of the data to be read, and sends a read command to the server by using a connection corresponding to the first virtual disk, where the read command includes a to-be-read Take the starting address and amount of data.

Exemplarily, the user can directly input the starting address and the amount of data of the data to be read in the first virtual disk to the terminal.

Correspondingly, the terminal receives the start address of the data to be read input by the user in the first virtual disk and the data amount of the data to be read, determines a connection corresponding to the first virtual disk, and sends a read to the server through the determined connection. Taking a command, the read command includes a start address and a data amount of data to be stored.

Step 506: The server receives, by using the connection, a read command sent by the terminal, where the read command includes a start address and a data amount of the data to be read in the first virtual disk, and determines a first virtual file corresponding to the connection.

Illustratively, the server receives the read command via a virtual core device associated with the connection, and the virtual kernel device then inputs the read command to the virtual user device. The server then obtains the read command from the virtual user device.

Step 507: The server determines, according to the start address and the first virtual file, an offset address of the first storage block unit and the data to be read in the first storage block unit.

Specifically, the server acquires, according to the file identifier of the first virtual file, the at least one unit identifier corresponding to the first virtual disk from the correspondence between the file identifier and the unit identifier stored by the cloud storage platform; according to the start address and the storage block unit The capacity determines an offset address of the first memory block unit and the data to be read in the first memory block unit from the corresponding memory block unit of each unit identifier.

Exemplarily, the capacity of each memory block unit in the cloud storage platform may be equal. It is assumed that the starting address of the data to be stored in the first virtual disk is at the position of 7G, and the capacity of each storage block unit is 5G. Thus, according to the start address and the capacity of the storage block unit, the determined first storage block unit is the second storage block unit corresponding to the first virtual disk and the offset address of the data to be read in the first storage block unit is 2G location.

Step 508: The server reads the data to be read from the first storage block unit according to the offset address and the data amount of the data to be read, and sends the data to be read to the terminal.

For example, assuming 2M of the data to be read, the server can read 2M of data to be read from the second storage block unit corresponding to the first virtual disk according to the location of the 2G, and send the to-be-readed to the terminal through the connection. data.
