A method, apparatus and system for writing a data object into an IP hard disk. When the data object is divided into a plurality of data fragments for being written, a server (11) queries a first key corresponding to the last sent data fragment and the length of the sent data fragment corresponding to the first key, and the first key corresponds to a first target IP hard disk (12); if the remaining storage capacity corresponding to the first key is larger than or equal to the length of the data fragments to be written, then keys corresponds to the data fragments to be written are determined to be identical with the first key; the offset of the data fragments to be written is determined according to the length of the sent data fragment corresponding to the first key; and a data writing request comprising the data fragments to be written, the first key and the offset of the data fragments to be written is sent to the first target IP hard disk (12); as a result, the server (11) can allocate the same key to the plurality of data fragments belonging to the same data object, thereby improving the rate of utilization of the storage space of the IP hard disk. |
