Abstract:

The object-based storage device （OSD） technology has become a hot topic in the field of storage systems these years. Compared with the traditional s torage technologies, the OSD system has better performance, scalability, security, and reliability. Based on the characteristics of OSD, a layout algori thm for objects and their copies is presented in this paper. The experimental results show that this algorithm can satisfy the requirements of system lo ad balancing and sealability.
