  • Patent number: 10678437
    Abstract: Embodiments of the present disclosure relate to a method and a device of managing input/output of a storage device. The storage device at least includes a first I/O port and a second I/O port. The method comprises receiving a first I/O request for the storage device, and determining a type of the first I/O request. Based on the type of the first I/O request, the first I/O request is dispatched to the first I/O port or the second I/O port. If the first I/O request is a read request, the first I/O request may be dispatched to the first I/O port, and if the first I/O request is determined as a write request, the first I/O request may be dispatched to the second I/O port. The method may reuse at least one of the first I/O port or the second I/O port.
