Redundant storage system, redundant storage method and redundant storage device

Abstract

The embodiment of the invention provides a redundant storage system, a redundant storage method and a redundant storage device, which solve the problem that a system structure based on traditional redundant storage is low in disaster tolerance treatment efficiency. The redundant storage system comprises a storage network, at least two storage nodes and at least two storage devices, wherein the at least two storage nodes are connected to the storage network; the at least two storage devices are connected to the storage network; each storage device comprises at least a storage medium; each storage node visits the at least two storage devices via the storage network; data is stored in at least a storage block of each storage device in the at least two storage devices visited by the same storage node in a redundant storage manner, and the storage block is the complete storage medium or one part of the storage medium.
本发明实施例提供了一种冗余存储系统、冗余存储方法和冗余存储装置,解决了基于传统冗余存储系统结构容灾处理效率低的问题。该冗余存储系统包括:存储网络;至少两个存储节点,连接至所述存储网络;以及至少两个存储设备,连接至所述存储网络,每个所述存储设备包括至少一个存储介质;其中,每个所述存储节点通过所述存储网络访问至少两个存储设备,被同一个存储节点访问的至少两个存储设备中的每个存储设备的至少一个存储块间以冗余存储的方式保存数据,其中,所述存储块是一个完整的存储介质或者是一个存储介质的一部分。
