Abstract

Embodiments of the invention provide a method for creating network volumes. The method comprises the steps of receiving a first network volume creation request sent by a management node by a first storage node; determining the side of to-be-distributed storage space of each storage node of a plurality of storage nodes according to RAID type information and size information of the network volumes; sending second network creation requests for each storage node respectively; assigning a logical address corresponding to each storage node for the storage space distributed for the storage node; and sending response information of the first network creation request to the management node, the response information of the first network creation request comprising the logical addresses of the network volumes, the logical addresses of the network volumes comprising the logical addresses corresponding to each storage node. Therefore, creation of the network volumes can be achieved.

Description

technical field [0001] The invention relates to storage technology, in particular to a network volume creation method, a data storage method, a storage device and a storage system. Background technique [0002] The traditional storage system uses a centralized storage server to store all data. The storage server is also called a storage node, which can contain multiple hard disks, and can be created according to the Redundant Array of Independent Disks (RAID) type among multiple hard disks. Ordinary volumes store data in ordinary volumes to achieve data redundancy. [0003] RAID is referred to as hard disk array for short. The basic idea is to combine multiple hard disks to form a hard disk array group, so that the performance can reach or even exceed that of a large-capacity hard disk. Depending on the selected version, RAID has the following advantages over a single hard disk: enhanced data integration, enhanced fault tolerance, and increased processing capacity or capac...
