<p>An embodiment of the present invention provides a data storage method, comprising: sending a performance information request message to a storage device, the performance information request message being used for querying performance information of a logic storage unit LUN in the storage device; receiving a response message of the performance information request message sent by the storage device, the response message comprising the performance information of the LUN; and obtaining a performance level of the LUN according to the performance information of the LUN, so as to write data to be written into the LUN of the corresponding performance level after receiving a data write instruction and according to the degree of hotness of the data to be written contained in the data write instruction. Therefore, LUN-level hierarchical storage can be achieved.</p> |
