设计一种基于SCSI总线技术的高速数据存储系统。系统采用PC机作为数据存储的主控单元,用2块SCSI硬盘组成磁盘阵,并设计简易的文件系统,最大限度地发挥SCSI硬盘的速度优势。在实际应用中系统存储带宽能够稳定地工作在100MB/s以上。使用ASPI开发SCSI接口程序,减少开发周期。在实际测试中,系统工作正常,表明了系统设计原理是正确的。
The design of high speed data storage system based on SCSI bus is discussed. This system takes full advantage of the SCSI disk, uses PC as the main control unit, uses two SCSI disks and designs a simple file system. According to practical measure,the bandwidth can exceed 100 MB/s. For the purpose of cutting design circle,using ASPI to implement the SCSI interface program. The test result indicates that the system works normally and the principle of the design is correct.
