A growing number of applications are choosing to use XML format to transfer data on internet or save data. As a result, volume of XML data is increasing speedy so that data centers use several to some dozens of servers to store XML data. In this case, there is a problem for power consumption in hard disks. This study proposes an XML data allocation algorithm for power consumption(XAPC). We analyze query patterns to find out which part of file are not accessed frequently and separate this part to different disks to cut down power consumption by putting the disk into a low power consumption mode. Finally, we evaluate power consumption of proposed algorithm using a simulator.
