High Performance Mass Storage System Based on Network Attached Disk Array
Network-attached Disk Array(Net-RAID)changes the traditional way of transfer focusing on the server to a new way focusing on the data, thus eliminating the server I/O bottleneck of traditional models.This paper proposes a high performance mass storage system based on Net-RAID.Adopting Centralized file Management and Distributed data Storage(CMDS-MSS) architecture, CMDS-MSS both improves data transfer rate,and reduces management cost. It achieves the goal of separating control and data flow and accelerating data transfer while expanding storage capacity at the same time.As a result,CMDS-MSS enhances the performance of the whole storage system enormously.
