Abstract

In order to provide huge files, for example, MPEG movie files or game files, from a provider to users, ultra high-speed file systems have been expected. We have made a prototype of ultra high-speed file system based on a personal computer (PC file system), which is optimized for sequential reading. Two basic technologies, "Continuous DMA" and "Multi-Layer Stripe" are proposed. The prototype system can achieve effective performance of 80Mbytes/s by means of only 9 hard drives.
