Problems solved by technology

However, storage devices of different companies and different architectures are not compatible with each other, and each set of its own products only supports the management software of its own manufacturer.
Therefore, information islands are formed between different storage devices, resulting in a waste of resources and increasing the work of operation and maintenance.

Embodiment Construction

[0040] Existing storage devices are mainly divided into two categories, one is represented by direct attached storage (Direct Attached Storage, DAS), network attached storage (Network Attached Storage, NAS) and storage area network (Storage Area Network, SAN), etc. Centralized storage; the other is distributed storage products deployed on X86 servers.

[0041] Centralized storage devices can also be classified into storage according to server types: closed system storage and open system storage. Closed systems mainly refer to mainframes, AS400 and other servers, and open systems refer to servers based on operating systems including Windows, UNIX, and Linux. ; Open system storage can be divided into: built-in storage and external storage; open system external storage can include: direct-attached storage (Direct-Attached Storage, DAS) and network storage (Fabric-Attached Storage, FAS) according to the way of connection ); the networked storage of the open system can also include...

Abstract

An embodiment of the invention relates to a data storage method and device which is applied in a storage system comprising distributed storage equipment and centralized storage equipment. A storage block in the centralized storage equipment is mapped as a virtual unit in the distributed storage equipment. The method includes: receiving a data write-in instruction which carries to-be-written-in data; dividing the to-be-written-in data into multiple data blocks, and determining storage position of each data block; if the circumstance that the storage position of at least one data block is the virtual unit, sending the data block to the centralized storage equipment through the distributed storage equipment; storing the data block into the storage block corresponding to the virtual unit by the centralized storage equipment.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular, to a data storage method and device. Background technique [0002] Existing data centers have purchased storage products from different companies and architectures for a long time in the past. However, storage devices of different companies and different architectures are not compatible with each other, and each set of its own products only supports the management software of its own manufacturer. Therefore, isolated islands of information are formed between different storage devices, resulting in waste of resources and increasing the work of operation and maintenance. [0003] At present, how to break through the barriers between different devices so that data can flow freely is an urgent problem to be solved. Contents of the invention [0004] The embodiments of the present application provide a data storage method and device to solve the compati...
