Design and Implementation of a Mass Storage System with Scalable Bandwidth and Capacity

摘要

This paper proposes a new storage system architecture called Net-RAID that establishes a direct network connection to clients based on the RAID. Separation of control and data messages is used to avoid memory-to-memory data copies between file server and storage subsystems. A mass storage system with scalable bandwidth and capacity is constructed based on the Net-RAIDs. The system bandwidth continuously and dynamically increases with the expansion of storage subsystem capacity. We construct system prototype and implement in FTP service system of our lab. Test result gives useful insights into the system performance behavior.
