Store device, storage system, and data transmission method

Abstract

The invention provides a store device, a storage system, and a data transmission method. The store device comprises a first controller, a second controller, a first interchange card, a second interchange card, and storage medium. The second controller and the first controller protect each other. The first interchange card is connected with the first controller. The second interchange card is connected with the second controller. The storage medium is connected with the first controller and the second controller. The first controller is used to calculate target storage device information of first to-be-stored data after the first to-be-stored data is received. When the target storage device is not a storage device, the first to-be-stored data and the target storage device information of the first to-be-stored data are sent by the first interchange card. The storage system comprises a plurality of storage devices, and the plurality of storage devices form a ring network.

Description

Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular, to a storage device, a storage system, and a data sending method. Background technique [0002] As the demand for data storage continues to grow and the performance requirements for storage arrays continue to increase, customers need to scale storage systems horizontally according to actual performance and capacity requirements. Storage system scale-out technology has emerged as the times require. By integrating storage systems Horizontal interconnection forms a large storage array. [0003] Storage system horizontal expansion refers to the ability to expand the storage system's business access capabilities, control capabilities, and hard disk access capabilities. Figure 1A Shows the structure diagram of the existing horizontally expanded central storage system. Figure 1A Each node 11 is a storage device, and each storage device is an independent physical entity an...
