Abstract: A method, device, and system for controlling a data read/write command in an NVMe over fabric architecture. In the method provided in the embodiments of the present disclosure, a data processing unit receives a control command sent by a control device, the data processing unit divides a storage space of a buffer unit into at least two storage spaces according to the control command sent by the control device, and establishes a correspondence between the at least two storage spaces and command queues, and after receiving a first data read/write command that is in a first command queue and that is sent by the control device, the data processing unit buffers, in a storage space that is of the buffer unit and that is corresponding to the first command queue, data to be transmitted according to the first data read/write command.

Abstract: A hot plug method, a host controller, a host, and a PCIe bridge device. The method includes: generating, by a host controller, a first notification packet, where the first notification packet includes hot plug interruption information, and the hot plug interruption information indicates that a first PCIe device is to be hot-plugged; sending, by the host controller, the first notification packet to a host, so that the host performs, according to the first notification packet, a hot plug operation corresponding to the PCIe device; and receiving, by the host controller, a second notification packet sent by the host, and sending the second notification packet to a user equipment controller, to facilitate the user equipment controller to instruct a user to insert or remove the PCIe device, where the second notification packet is for indicating that the hot plug operation corresponding to the PCIe device is completed.
