Abstract

In this paper we will address the architecture and implementation of an object-based storage system, and describe the design of the intelligent object-based storage device (OSD), which is built on embedded system of RAID. Our OSD is designed for general purpose according to the T10 standard. It not only can be easily added to the massive network storage system over TCP/IP to increase the quantity and quality of the storage system by adding intelligent OSD to the storage, but also can reduce the TCO (total cost of ownership).Also we extend the T10 standard by adding the object physical layout information to help shorten the access latency and to increase the intelligence for our OSD.
