Abstract
In order to improve accessibility and efficiency of a cloud system, this work proposed a mechanism to integrate Ceph, HDFS and Swift based on the OpenStack. We first build a heterogeneous storage environment including Ceph, HDFS and Swift based on the open source OpenStack and then measure their performances. To integrate storage services of Ceph, HDFS and Swift, we propose a proportion-based file distribution mechanism. The proportion for file partition is dependent on the remaining storage capacity so that we can distribute those sub files to different storage. This mechanism also enhances the file security. In addition, a high usability user interface is provided so as to make the proposed system more friendly. Experimental results show the efficiency of our system.
