A method for implementing storage of a file in an IP disk, wherein the IP disk is connected to a network, and a server that accesses the network by using a network adapter accesses the IP disk by using the network, and a file stored in the IP disk is managed by using a key value, and the method comprising: receiving an operation request for a target file generated by a server by using an existing application that is incompatible with the key value, wherein the target file has a unique corresponding key value; converting operation information of the operation request into a key value of the target file; acquiring, according to the key value, an identifier of a target IP disk corresponding to the operation request; and sending, to the target IP disk identified by the identifier, the operation request carrying the key value; characterized in that the converting operation information of the operation request into a key value of the target file comprises: converting the operation information of the operation request into the key value of the target file by using a type length value algorithm, which recodes the operation request using a same coding standard as that for the key value of the IP disk; wherein the operation information comprises a type of the target file, a path of the target file, a content identifier of the target file, and a content length of the target file; and the converting the operation information of the operation request into the key value of the target file by using a type length value algorithm comprises: converting the type of the target file into a first subkey value; converting the path of the target file into a second subkey value; converting the content identifier of the target file into a third subkey value; converting the content length of the target file into a fourth subkey value; and acquiring the key value of the target file, wherein the key value comprises the first subkey value, the second subkey value, the third subkey value, and the fourth subkey value. receiving an operation request for a target file generated by a server by using an existing application that is incompatible with the key value, wherein the target file has a unique corresponding key value;
