[0047] In an embodiment, the tiered storage method of the virtual storage system includes:
[0048] Step S10, obtaining the business strategy preset for the business object;
[0049] In this embodiment, the business strategy preset for the business object is first obtained, where the business strategy can either be set by the user according to their own performance requirements for the business object, or can be based on the type of business object. The corresponding business strategy automatically generated by the preset rules is not limited here.
[0050] Users can set different business strategies according to different business needs. In one embodiment, the business strategy set by the user includes solving business needs such as shopping website promotions, ticket reservations, etc., which can cause the number of businesses to skyrocket in a short period of time and cause the corresponding website services to freeze and other problems, and can also include solving when the startup is idle In the case of a long-term virtual machine, because the virtual machine's perception of upper-layer computing is slow, business requirements such as virtual machine service stalls, etc., may also include solving the problem of data for performing backup operations in a long time and supporting high-performance reading.

Specifically, the business problems of the website service freeze, the virtual machine service freeze, and the long retention time of the backup data are not limited here.
[0051] Step S20, calculating and generating hierarchical storage strategies corresponding to the business data of different business objects according to the business strategy;
[0052] Because the specific storage method of the tiered storage virtual storage system is relatively transparent to the user, and the user cannot obtain the specific storage location of the data, it is necessary to convert the business strategy set by the user on the visual terminal interface into the virtual storage through the hyper-converged virtual computing system The tiered storage strategy that the system can execute. In one embodiment, the business strategy is transmitted to the hyper-converged virtual computing system through the network. Specifically, the network includes a wired network and/or a wireless network, which is not limited herein. When the hyper-converged virtual computing system obtains the service policy information, the virtual computing system calculates and generates a tiered storage policy according to the service policy. The tiered storage virtual storage system can perform data migration according to the tiered storage policy. operating.
[0053] Step S30: Based on the layered storage strategy, different service data are stored in storage media with corresponding read and write performance.
[0054] When the tiered storage virtual storage system receives the tiered storage strategy, the virtual storage system will, according to the specific business requirements recorded by the tiered storage strategy, remove the data that needs to perform high-performance read and write within the time period set by the user from the current Some storage media are migrated to storage media that support high-performance read and write operations. When the high-performance read-write operation is completed, the data that no longer needs to perform the high-performance read-write operation is migrated from the storage medium that supports the high-performance read-write operation to the storage medium that only supports the low-performance read-write operation. Specifically, the storage medium that supports high-performance read-write operations includes solid-state hard disk storage media, and the storage medium that only supports low-performance read-write operations includes mechanical hard disk storage media, which is not limited herein.
[0055] In this embodiment, the tiered storage strategy corresponding to the business data of different business objects is calculated and generated by the business strategy preset for the business object; and based on the tiered storage strategy, the different business data is stored in a storage medium with corresponding read and write performance. As the data can be hierarchically stored according to the business strategy preset by the specific business requirements, the integration of the data hierarchical storage and the specific business requirements is closer, and the data can be flexibly layered according to the different business requirements set by the user storage.
[0056] Further, in other embodiments, the above step S10 may include:
[0057] Receive the business strategy configured by the user for different business virtual machines according to business requirements in the preset business configuration interface.
[0058] In this embodiment, the user can set the service policy configured by the service virtual machine matching different service requirements through the terminal interface. Specifically, the terminal interface includes a mobile terminal interface and/or a desktop terminal interface, which is not limited herein. In an implementation manner, the service policy is matched with a service virtual machine, and the execution of the specific service policy is controlled by the service virtual machine, wherein the service policy includes the on time and off time of the service virtual machine . The service virtual machine can be automatically created through the service policy received by the terminal, and the specific creation method is not limited here.

Describe the migration operation of business data. After the preset time period, the cooling operation of the service data is performed. Since the end time of executing the migration operation is before the start time of executing the high-performance pair operation, when the business data completes the migration operation, the high-performance read-write operation has not yet been started, ensuring that when the high-performance read-write operation is started, The data is already in a storage medium that supports high-performance read and write operations, avoiding the delay caused by the sudden execution of a large amount of data read and write operations in a short time.
[0073] In another implementation manner, the migration operation is started when the preset time period is reached. By reducing the heating time of the service data, such as changing the data read and written ten times from cold data to hot data, the data is changed from only The transmission of the storage medium that supports low-performance read and write operations to the storage medium that supports high-performance read and write operations reduces the data that is read and written once from cold data to hot data. Specifically, the number of reads and writes is not limited here. After the preset time period, the cooling operation of the service data is performed. By reducing the heating time of the business data, the migration time that needs to be consumed when the business data performs high-performance read and write operations is saved, and the delay problem caused by the read and write operations of a large amount of data suddenly executed in a short time is avoided.
