  • Patent number: 10372340
    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.
