Abstract

A description is given of a system that contains the online storage of approximately 15 million patents or 30 Tbytes of data. Magnetic disk storage is used on an IBM plug-compatible mainframe to store the indices. Optical storage which offers the best cost/performance ratio, is used to store the images of the patents. Two types of optical storage devices are used: the removable optical disk and the jukebox. Removable optical disks have a relatively fast access time and therefore they are used to store the most frequently accessed patents. The jukeboxes have a relatively slow access time and are used to store the remainder of the patents. Both the removable optical disks and the jukeboxes are controlled by Unix supermicrocomputers such as the SUN-3. The intelligent controllers contain cache magnetic storage for matching the data transfer speed of the optical drives with the network. All of the removable optical disks and jukeboxes are connected together using packet-switching digital switches which offer an off-the-shelf IEEE 802.3 network with guaranteed end-to-end throughput. >

30tb的大容量存储架构

描述了一个包含大约1500万项专利或30 tb数据的在线存储的系统。在IBM插件兼容的大型机上使用磁盘存储来存储索引。采用性价比最佳的光存储技术来存储本专利的图像。使用两种类型的光存储设备:可移动光盘和自动点唱机。可移动光盘具有相对较快的访问时间，因此它们用于存储访问最频繁的专利。自动点唱机的存取时间相对较慢，用于存储剩余的专利。可移动光盘和自动点唱机都是由SUN-3之类的Unix超级微型计算机控制的。智能控制器包含缓存磁存储器，用于使光驱的数据传输速度与网络相匹配。所有可移动光盘和自动点唱机都使用分组交换数字交换机连接在一起，提供一个现成的IEEE 802.3网络，保证端到端吞吐量。>
