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.
