摘　　要：面向对象存储是近年来存储系统领域的研究热点之一。与传统存储系统相比,面向对象存储系统具有高性能、可伸缩、更安全、更可靠的特点。针对面向对象存储的特点,本文给出了一种对象和数据副本的布局方法,并在原型系统上验证了实现。实验测试表明,这一布局方法能够很好地实现系统的负载均衡和可伸缩性。The object-based storage device （OSD） technology has become a hot topic in the field of storage systems these years. Compared with the traditional storage technologies, the OSD system has better performance, scalability, security, and reliability. Based on the characteristics of OSD, a layout algorithm for objects and their copies is presented in this paper. The experimental results show that this algorithm can satisfy the requirements of system load balancing and sealability.
