Abstract: This disclosure provides a method and an apparatus for accessing a solid state disk (SSD). The method is applied to a storage node, the storage node includes a network interface card and an SSD, and the network interface card includes a memory. The network interface card receives a data write request sent by a client, where the data write request includes to-be-written data. The network interface card writes the to-be-written data to the memory of the network interface card, and the SSD obtains the to-be-written data from the memory of the network interface card and writes the to-be-written data to the SSD.

Abstract: In a method for processing a server message block (SMB) service fault, a first storage device generates a file handle according to a first file open instruction from a host, and sends the file handle to a second storage device. The second storage device stores the file handle as a backup handle. The second storage device activates an Internet Protocol (IP) address of the first storage device according to fault information from the first storage device, and establishes a communication connection to the host. After the second storage device determines a file handle matches the handle identifier, the second storage device opens a file. Hence, when a storage device that processes an SMB service is faulty, the SMB service may be taken over by a secondary storage device such that the SMB service is executed without interruption.

Abstract: Embodiments of this application disclose a data processing method, which is used in a storage system. The method in embodiments of this application includes: A network interface card device receives a first access request of a first client, where the first access request carries an access address; the network interface card device detects whether the first access request has a conflict; and when the network interface card device detects that the first access request has a conflict, the network interface card device processes the conflict according to a processing policy. In embodiments of this application, when a conflict occurs, the network interface card device processes the conflict according to the processing policy. This avoids conflict management performed by a processor of a storage node, and saves a resource of the processor of the storage node.

Abstract: An image processing method includes obtaining multiple video frames, where the multiple video frames are collected from a same scene at different angles and determining a depth map of each video frame according to corresponding pixels among the multiple video frames; supplementing background missing regions of the multiple video frames according to depth maps of the multiple video frames, to obtain supplemented video frames of the multiple video frames and depth maps of the multiple supplemented video frames. The method also includes generating an alpha image of each video frame according to an occlusion relationship between each of the multiple video frames and a supplemented video frame of each video frame in a background missing region and generating a browsing frame at a specified browsing angle according to the multiple video frames, the supplemented video frames of the multiple video frames, and alpha images of the multiple video frames.
