HUST RAID: high performance RAID in real-time system

We discuss the design issues of a high performance RAID prototype in a real-time system, called HUST RAID. Based on the architecture and the real-time process model of HUST RAID, a multiple queue real-time I/O scheduling algorithm and new buffer management policy are proposed. We also introduce the software design issues of the control system. From the performance measurement results of HUST RAID, we can see that the performance of the HUST RAID system is excellent.
