The Object-based Storage System (OBS) has been proposed as a novel information storage technology in adaptation to the explosive growth in information quantity under the next-generation internet. The OBS treats all storage devices (OSD) and data information as objects, hence, the issues like reducing access delay over WAN, saving limited bandwidth and enhancement of data validity become problems related to the overall performance of OBS. To address these problems, we have the replica-based OBS, which brings forward a new issue on how to manage these replicas. In this paper, we present a multi-dimensional replica management scheme, and study the object searching performance within this mode. We deliver the optimal tree & improved one-path tree on the basis of similarity searching, with detailed replica indexing algorithm and emulation tests. The result of these experiments justifies their better performance in contrast to normal similarity-based indexing algorithm, with lower system cost.
