Abstract: A storage system includes a switch and a plurality of storage nodes. The switch is configured to receive a first request from a client. The first request includes an identifier of a storage partition. The switch queries an entry in a forwarding table based on the identifier to determine a target storage node in the plurality of storage nodes. The entry includes a mapping relationship between the identifier and the target storage node. The switch sends the first request to the target storage node. The target storage node is configured to receive the first request from the switch.

Abstract: Embodiments of the present disclosure provide a storage system, including a distribution apparatus and a storage device; the storage device includes at least two storage controllers and multiple storage units, where each storage unit is configured with any one of the at least two storage controllers as a home storage controller; and the distribution apparatus includes a front-end interface and at least two back-end interfaces, where the front-end interface is configured to connect to a host device, and each back-end interface is connected to each storage controller in a one-to-one correspondence manner. According to the technical solutions provided in the present disclosure, the distribution apparatus parses an IO read/write instruction, so that the IO read/write instruction can be accurately sent to the home storage controller, which avoids forwarding the IO read/write instruction between the storage controllers, thereby improving IO processing efficiency of the storage system.
