Abstract: A foldable electronic device includes a first housing and a second housing that are rotationally connected to each other by means of rotating shafts located on two sides, and an antenna. The first housing can switch between an unfolded state and a folded state relative to the second housing, and the antenna is disposed in a closed slot. The antenna includes a first antenna segment and a second antenna segment that are sequentially connected and disposed in a length direction of the antenna. One end of the first antenna segment is connected to a ground plate of the first housing. The first antenna segment extends from one end toward a direction in which an opening/closing region of the first housing and the second housing in the unfolded state is away from the first housing.

Abstract: This application discloses a network interface card so as to improve reliability of a storage apparatus using an RDMA network and improve storage access performance of a single QP connection. A network interface card includes a parser and at least one shared connector, where the parser is configured to distribute a received first remote direct memory access RDMA packet to a first shared connector in the at least one shared connector; and the first shared connector is configured to establish a QP connection to a peer network device, and determine a first queue pair QP corresponding to a first controller based on the first RDMA packet, so as to implement communication with the first controller, where the first shared connector is separately connected to a plurality of controllers including the first controller, and one QP corresponding to each of the plurality of controllers corresponds to the first shared connector.
