The parallel I/O architecture of the high-performance storage system (HPSS)

Datasets up to terabyte size and petabyte total capacities have created a serious imbalance between I/O and storage-system performance and system functionality. One promising approach is the use of parallel data-transfer techniques for client access to storage, peripheral-to-peripheral transfers, and remote file transfers. This paper describes the parallel I/O architecture and mechanisms, parallel transport protocol (PTP), parallel FTP, and parallel client application programming interface (API) used by the high-performance storage system (HPSS). Parallel storage integration issues with a local parallel file system are also discussed.
