Abstract

The embodiment of the invention provides a data storage method and device, and relates to the field of data storage. The specific implementation scheme is as follows: receiving a data storage request,wherein the data storage request comprises to-be-stored data and a storage demand; generating a consistent hash storage look-around view according to the storage requirement and the user permission,wherein the consistent hash storage ring view comprises a part of content of the consistent hash storage ring, and the consistent hash storage ring comprises each storage device and a closed-loop datastructure of a hash value corresponding to the storage device; performing consistent hash operation on the to-be-stored data to obtain a hash value; searching a storage device corresponding to the hash value in the consistent hash storage look-around view; and converting the to-be-stored data into a data format matched with the storage device, and storing the to-be-stored data into the storage device. The data storage efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data storage technology. Background technique [0002] Amazon S3 (Amazon Simple Storage Service, Amazon Simple Storage Service) provides a simple web service interface through which any amount of data can be accessed, stored and extracted from anywhere on the network at any time. The standardized Restful (Representational State Transfer) interface is a set of constraints and attributes determined based on the Hypertext Transfer Protocol. It is a software construction style designed to provide global information network services. Network services conforming to or compatible with this architectural style allow clients to issue requests for accessing and operating network resources with uniform resource identifiers. [0003] At present, there are some problems when connecting different storage devices (such as disk arrays, tape libraries, network storage server device...
