Abstract

An embodiment of the present invention provides a storage apparatus, and relates to the technical field of computers, so as to meet a storage RAS characteristic of a multi-path server. The storage apparatus comprises at least two storage controllers, at least two storage expansion modules and a storage disk. The at least two storage controller are connected to a processor of a multi-path server, and each storage controller is connected to each storage expansion module among the at least two storage expansion modules; the at least two storage expansion modules are connected to the storage disk; a first storage controller is used for performing conversion between data of a first data type and data of a second data type, and sending the data of the second data type to a master storage expansion module, and when a second storage controller has a failure, processing the conversion between the data of the first data type, which is processed by the second storage controller, and the data of the second data type; the storage expansion module is used for storing the data of the second data type into the storage disk; and the storage disk is used for storing the data of the second data type.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a storage device. Background technique [0002] With the rapid development of communication technology, the number of CPUs (Central Processing Unit, central processing unit) included in the server is also increasing, and multi-channel server applications are born. A multi-channel server means that there are multiple physical CPUs in the server, and the number of physical CPUs in the server determines the number of "multi-channels" in the server. For example, if the server contains 16 physical CPUs, it is a 16-way server. The more physical CPUs in a multi-channel server, the higher its ability to process data. Therefore, 32-channel and 64-channel servers have become the development trend of multi-channel servers. [0003] With the development of multi-way servers, the storage of multi-way servers is constantly developing in the direction of RAS (Reliability, Availabili...
