Implementation and Performance Evaluation of an Object-Based Storage Device

Object-based storage system (OBSS) has led to a new wave in network storage area . Object-based storage device (OSD) which is the cornerstone of OBSS plays a decisive role in the performance of the whole OBSS. This paper describes how we implemented an object-based storage device which adopts a unique hardware architecture based on switching fabric supporting parallel data transfer in multiple I/O channels, and a new object-based storage device file system (HustOSDFS) that can reduce the software overloads to achieve high performance. The experimental evaluation results show that the OSD performs well for system performance. Furthermore, the OSD provides characteristic of large capacity and low cost.
