Abstract: Embodiments of the present invention disclose a data processing solution. In this solution, a hard disk receives a call instruction sent by a server, where the call instruction includes a function identifier of a to-be-called function and an operation address; and the hard disk calls the function in the hard disk based on the function identifier, and performs, based on the function, an operation on data corresponding to the operation address.

Abstract: Embodiments of the present invention disclose a method and an apparatus for implementing protection of RAID in a file system, and are applied in the field of communications technologies. In the embodiments of the present invention, after receiving a file operation request, the file system needs to determine the type of a file to be operated as requested by the file operation request, and perform file operations in a hard disk drive of the file system directly according to a file operation method corresponding to the determined file type, that is, a RAID data protection method. Therefore, corresponding file operations may be performed in a proper operation method according to each different file types, and data of an important file type is primarily protected, thereby improving reliability of data storage.
