Improve the performance of web service by parallel I/O system

Over years, a lot of people have devoted themselves to the research of parallel I/O. In some applications, Parallel I/O, whose goal is to improve the performance of a system by enhancing its throughput capacity and accomplished by reducing bottlenecks in I/O path: no single I/O device, no single I/O bus, and no single network path, has been used. Nowadays, various web services have very high requirement of throughput. In this paper, we discuss a parallel I/O architecture and describe how to improve the performance of web service with the parallel I/O system which is at the back of database sever in the 3-tiers architecture and provides transparent data access. To provide parallel I/O, three software requirements have to be satisfied: application interface, underlying high performance data storage mechanism, and tools for file manipulation. And as the parallel I/O system is used in web applications, parallel I/O will interact with database server.
