Problems solved by technology

[0004] Existing hierarchical storage systems usually migrate data in units of files. In the application environment of large files (greater than 1GB), too many file migrations will increase the operating pressure of the entire storage system on the one hand, and on the other hand, larger Files take longer to migrate and complicate the migration process

Embodiment 1

[0035] This embodiment provides an object-based storage system, which is different from the traditional hierarchical storage system with files as the unit, but uses objects as the basic unit to store data hierarchically, and stores them in different In the storage pool, it is especially suitable for the application environment of large files. Specifically, the storage system provided in this embodiment at least includes multiple storage pools, a tiering policy module, and an object migration module.

[0036] Among them, the storage pool stores object data of different heat levels;

[0037] The object migration module is mainly responsible for migrating the object data specified by the classification policy module between storage pools with different performances;

[0038] The grading strategy module mainly analyzes the object data in each storage pool, and filters out the object data that needs to be migrated according to the pre-set grading strategy (that is, filters out the...

Embodiment 2

[0047] This embodiment introduces an object-based storage method, which can be implemented relying on the storage system provided in Embodiment 1. Specifically, the method includes the following operations:

[0048] Store object data with different heat levels in multiple storage pools;

[0049] Perform heat analysis on the object data in each storage pool, first filter out the object data that needs to be migrated according to the pre-set grading strategy, and then migrate the object data to the corresponding storage pool according to the filtered information about the object data that needs to be migrated middle.

[0050] Among them, the grading strategy set in advance includes one or more of the following conditions:

[0051] Reach or exceed the set access frequency, and the latest access time is within the set time range.

[0052] Of course, the above method also includes management operations, that is, managing multiple storage pools, and recording the storage location...

Abstract

The invention discloses a storage system based on an object and a storage method of the storage system based on the object, and relates to the field of information storage. The storage system based on the object comprises a plurality of storage pools, a classification strategy module and an object moving module, wherein the storage pools store object data of different heat-degree levels, the classification strategy module carries out heat-degree analysis of the data of the objects stored in each storage pool, screens out object data needing to be moved according to the preset classification strategy, and transmits the information of the objective data needing to be moved to the object moving module. The object moving module moves the object data to corresponding storage pools according to the information of the object data transmitted by the classification strategy module. The invention further discloses a storage method based on the object. The storage system based on the object and the storage method of the storage system based on the object reduce moved data amount, at the same time greatly simplify processing of data during the data moving process due to the fact that the object is small, accelerate the moving process, and are particularly suitable for an application environment of large files.

Description

technical field [0001] The invention relates to the field of information storage, in particular to an object-based storage system and a storage method thereof. Background technique [0002] The object storage system is a network storage system with an object as the access interface. The object storage file system provides a set of access interfaces similar to file operations, and converts file operations into object access, so that various applications of users do not need to be modified. It can run on the object storage system. Adopting the object interface can make the object storage system have advantages in cross-platform data sharing, security, performance and intelligence. Because the object storage system has the above advantages, many universities, research institutions and companies have conducted research on object storage technology and achieved many results. Lustre, the first open source object-based cluster file system, has been widely used in the field of hig...
