项目摘要

Second-storage systems which have very large capacity is essential for large image processing. Recently, hard-disk systems tends to be smaller and cheaper in spite of their high performance and reliability.Our research goal is to present the architecture of the high performance disk array, by utilizing small hard-disks, which is suitable for large image processing. Our proposed architecture employs the hierachical storage system in which tape devices are also combined in order to hold very large images, since it is not realistic that all large image data is resident on hard-disk drives.We constructed the RAID disk array system which consist of 16 data disk, one parity disk and one spare disk. Since each disk has 600MB capacity and 2.0MB / sec data transfer rate, this disk array system provides in total almost 10GB capacity and 30MB / sec data transfer rate. We attach this system to SUN work station by using specialized S-bus interface board, which is developed especially in order to support high bandwidth between the disk array and SUN Then, we combined 8mm tape archivers into our system and implemented a large image processing system to migrate image data in the hierarchical storage systems. At last, we applyed our system for large remote sensing image processing and confirmed efficiency of our architecture.

具有非常大容量的第二存储系统对于大型图像处理是必要的。近年来，硬盘系统虽然具有高性能和高可靠性，但却趋向于小型化和廉价化，我们的研究目标是提出一种利用小型硬盘的高性能磁盘阵列结构，以适合于大容量的图像处理。我们提出的体系结构采用了分层存储系统，其中磁带设备也结合起来，以保持非常大的图像，因为这是不现实的，所有的大型图像数据都驻留在硬盘驱动器。我们构建了RAID磁盘阵列系统，由16个数据磁盘，一个奇偶校验磁盘和一个备用磁盘。由于每个磁盘有600 MB的容量和2.0 MB/秒的数据传输速率，这个磁盘阵列系统提供了近10 GB的容量和30 MB/秒的数据传输速率。我们使用专门为支持磁盘阵列与SUN工作站之间的高带宽而开发的S总线接口板将该系统连接到SUN工作站上。然后，我们将8 mm磁带归档器结合到我们的系统中，实现了一个大型图像处理系统，用于迁移分层存储系统中的图像数据。最后，将该系统应用于大规模遥感图像处理，验证了该体系结构的有效性。
