Paper Abstract

On the commercial available server, the great workloads on CPU generally limit the performance of Input/Output (I/O) or delay the response time. A Network-Attached Storage Device (NASD) is developed to meet the scalability requirement of mass multimedia storage. The evaluating experiments in this paper indicate that the bottleneck of data transmission is not the capability of CPU, but the network and reading/recording speed of physical storage devices. To improve the performance of multimedia storage system, a scheme of NASD-based multi-port storage area network is presented. In the new system composed of one manager and several NASDs, the manager only assigns the task of data processing to the NASDs. The NASDs can dynamically generate the virtual files and sent them to clients directly. Act as a virtual server, the storage system can provide the multi-port service for the different clients and different requirements.
