Problems solved by technology

[0003]In the existing technology, the object index information is usually managed by the central management node in the object storage system. When the data objects reach tens of millions, the pressure on the database of the central management node The sharp rise, when the central management node rock machine or other abnormalities, can not provide external services, so that the stability of the system cannot be guaranteed

Abstract

The invention provides an object storage method and device, which are applied to a gateway of a distributed storage system, the distributed storage system further comprises at least one storage node,the method comprises the following steps: receiving a data uploading request uploaded by a client, wherein the data uploading request comprises an object identifier ID and an object size K; accordingto the size K of the object and the residual storage space of each online storage node in the distributed storage system, obtaining the size K of the object; according to a load balancing mode, determining the sizes of object fragments used for storing object data corresponding to the object identification ID, in all online storage nodes, wherein the sum of the sizes of the object fragments in theonline storage nodes is the size K of the object; and controlling the object data corresponding to the to-be-stored object identifier ID to be stored to each online storage node according to the object fragment size of each online storage node, thereby ensuring that the capacity of the storage nodes in the distributed storage system is uniformly distributed, and achieving an effect of load balancing of each online storage node.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to an object storage method and device. Background technique [0002] In the field of storage technology, it mainly includes three storage methods, namely file (File) storage, block (Block) storage and object-based storage (Object-based Storage). Among them, file storage is a technology that integrates independent data into a centralized management data center to facilitate access to different hosts and application servers; block storage refers to a redundant array of independent disks (RAID) set, A controller joins a group of disk drives, and then provides fixed-size RAID blocks as logical unit number (LUN) volumes; object storage is a new network storage architecture, objects contain data, and each object is in a file called In the same level as the flat address space of the storage pool. [0003] In the existing technology, the object index information is usual...
