Abstract

The present invention provides a storage device, a storage system, and a data transmission method. The storage device comprises a first controller, a second controller, a first exchanging card, a second exchanging card, and a storage medium. The second controller and the first controller protect each other. The first exchanging card is connected to the first controller. The second exchanging card is connected to the second controller. The storage medium is connected to the first controller and the second controller. The first controller is used for, after receiving first to-be-stored data, calculating target storage device information of the first to-be-stored data, and is used for, when the target storage device is not a storage device, sending the first to-be-stored data and the target storage device information of the first to-be-stored data by using the first exchanging card. The storage system may comprise multiple storage devices, and the multiple storage devices form a ring network.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, 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 improve, customers need to scale out storage systems based on actual performance and capacity requirements, and storage system scale-out technology emerges as the times require. Horizontal interconnects form large storage arrays. [0003] Horizontal expansion of the storage system means that the service access capability, control capability, and hard disk access capability of the storage system can be expanded. Figure 1A shows a schematic structural diagram of an existing horizontally expanded central storage system, in Figure 1A Among them, each node 11 is a storage device, and each storage device is a physical entity independent of each other, and is l...
