    Abstract: This application describes a method, a system, and a related device for network attached storage (NAS) data access. The method includes receiving, by a NAS client, an access request message, and determining an operation object according to information about to-be-accessed target data in the access request message, where the operation object includes a directory and/or a file to which the target data belongs. The method may also include generating a first direct memory access file system (DMAFS) packet according to a format described by using a preset file system type, where the preset file system type is used to describe a format of a DMAFS packet. Furthermore, the method may include sending the first DMAFS packet to an acceleration apparatus, so that the acceleration apparatus converts the operation object and an operation type that are in the first DMAFS packet into NFS data, and encapsulates the NFS data into a network protocol packet and sends the network protocol packet to a NAS server.

    Abstract: A method for implementing NVMe over fabrics includes generating, by a terminal, a NVMe instruction, where the NVMe instruction indicates a data read operation or a data write operation. The method further includes sending, by the terminal by using remote direct memory access (RDMA), the NVMe instruction to a submission queue (SQ) that is stored in a server. When the NVMe instruction indicates the data read operation, the method includes receiving, by the terminal by using the RDMA, to-be-read data sent by the server. Alternatively, when the NVMe instruction indicates the data write operation, the method includes sending, by the terminal, to-be-written data to the server by using the RDMA. The method further includes receiving, by the terminal, an NVMe completion instruction sent by using the RDMA by the server; and writing, by the terminal, the NVMe completion instruction into a completion queue (CQ) that is set in the terminal.

    Abstract: A data processing method and a storage apparatus are disclosed. The data processing method includes: receiving, by an NVMe storage device, an NVMe write command sent by a host, where the NVMe write command carries a key and a value pointer, the value pointer points to first storage space, and the first storage space is used to store a value; obtaining, by the NVMe storage device, the key from the NVMe write command and a value length, and allocating second storage space to the value according to the value length, where the second storage space is in the NVMe storage device; and obtaining, by the NVMe storage device, the value from the host, and storing the value in the second storage space.
