Virtual storage system and tiered storage method thereof

Abstract

The invention discloses a tiered storage method of a virtual storage system. The method comprises the following steps that service strategies preset for service objects are obtained; according to the service strategy, a tiered storage strategy corresponding to service data of different service objects is generated through calculation according to the service strategies; on the basis of the tiered storage strategy, the service data of the different service objects are stored into a storage medium with the corresponding read-write performance. The invention further discloses the tiered storage virtual storage system. Due to the fact that data tiered storage can be performed according to the service strategies preset for the specific service requirements, data tiered storage and specific service requirements are combined more tightly, and flexible data tiered storage can be performed according to different service requirements set by users.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a layered storage method of a virtual storage system and a virtual storage system. Background technique [0002] Virtual storage technology refers to the centralized management of multiple storage media modules such as hard disks and RAID through certain means, so that all storage modules can be uniformly managed in a storage pool, providing users with large-capacity, high-performance Data transfer experience. Hyper-converged infrastructure refers to the combination of elements such as software backup, snapshot technology, deduplication, and online data compression in the same set of unit equipment on the basis of resources and technologies such as computing, network, storage, and server virtualization. Aggregate the infrastructure of multiple sets of unit equipment, realize the seamless horizontal expansion of modularization, and form a unified resource pool. IOPS refers to ...

AI Technical Summary

Problems solved by technology

[0003] Existing virtual storage systems can only rely on their own hierarchical storage mechanism to store cold data that is rarely accessed in the mechanical hard disk storage medium, and store hot data that is frequently accessed in the solid-state hard disk storage medium, and cannot flexibly adapt to various user needs. Business requirements, such as:

[0004] 1. In the face of sudden calculations such as shopping website promotions, ticket reservations, etc., the virtual storage system has a shortage of read and write performance in a short period of time, because it takes a certain amount of time to migrate from cold data to hot data. Inside, cold data cannot quickly become hot data;

[0005] 2. The virtual storage system is relatively insensitive to upper-level computing. For example, when the virtual machine stops running for a long time, the running data of the virtual machine changes from hot data to cold data, and the virtual machine will freeze when it is used again;

[0006] 3. The combination of virtual storage system and business requirements is not close enough. For example, when performing nightly backup, due to continuous reading and writing of backup data, the data changes from cold data to hot data. After the backup is completed, the backup data cannot be changed in a short time. It is cold data, which occupies the space of high IOPS storage media with limited capacity
