Embodiment Construction
[0040] The implementation steps of the method for writing a file operation by accessing the client in the present invention are as follows:
[0041] 1. The user submits a file writing request to the access interface module of the access client of the access client, and the request includes the identifier of the file to be written, the data to be written, and the starting offset and length of the data segment to be written;
[0042] 2. After the access interface module simply encapsulates the file write request, it is handed over to the view request module, which requests the view information required for the write operation from the metadata server;
[0043] 3. The metadata server performs simple authentication on the request. If the authentication is not passed, an error message will be returned to the access client; if the authentication is passed, it will transfer to the server distance comparison module, estimate and select the copy storage server closest to the user;
