| Abstract(in English) | Network file servers with high-speed read performance are required as networks are sped up. The authors have been developed a high-speed file server with 105 Mbytes/s read performance based on MS-DOS file system on the real-time OS (VxWorks). In this paper, new techniques of design and implementation for a high-speed file server based on UNIX are proposed. The techniques are to gather contiguous blocks on UFS (UNIX file system) for reducing the number of command requests from the file system to the device driver, and direct access method for cutting through the butter cache mechanism. Our experimental file server based on Open BSD Unix achieved 100 Mbytes/s read performance by means of only 9 hard drives in RAID level 0. |
