PURPOSE: A data management method is provided to divide a chunk and distributively arrange the divided chucks if the frequency of client requests increases. CONSTITUTION: The first response IOPS(Input Output Per Second)(Ap) and the second response IOPS(Tp) are set in advance(S201). A request IOPS(Dp) about a specific chunk of a data server is measured(S202). It is determined whether the request IOPS(Dp) belongs to a range formed between the first response IOPS(Ap) and the second response IOPS(Tp)(S203). If the request IOPS(Dp) is bigger than the first response IOPS(Ap), a specific chunk is divided by n and is distributively arranged in the data server(S204). |
