项目摘要

The rapidly growing disparity between processor and I/O performance must be addressed. Two intriguing trends in storage systems are the appearance of new technologies that suffer from asymmetric read-write performance, and the widening gap between data transfer rate and access time. A current example is a tertiary storage system with an automated library mechanism. Such a system exemplifies the wide performance gap between data transfer rate and access time due to mechanical media handling.The goal of this work is to address these issues through the development of techniques for high-performance integration of automated tertiary storage libraries. These issues include:1. Addressing the issue of read-write performance asymmetry, though the use of a log-structured, write-buffered architecture.2. The minimization of mechanical access delays, by pre-grouping related data on the same media volume, as it is migrated from local storage.This research will be of direct benefit to today's growing storage needs by allowing high-performance access to vast storage. It addresses the important issue of latency reduction in cases where data rate far exceeds access speeds. It also enables the efficient general-purpose adoption of emerging storage technologies, such as magneto-optical and volume holographic, by alleviating problems of read-write performance asymmetry.

必须解决处理器和I/O性能之间快速增长的差异。存储系统中的两个有趣的趋势是出现了不对称读取功能的新技术，以及数据传输速率和访问时间之间的差距扩大。当前的示例是具有自动化图书馆机制的第三级存储系统。这种系统体现了由于机械媒体处理而引起的数据传输速率和访问时间之间的较大性能差距。这项工作的目的是通过开发自动化高等第三级存储库的高性能整合技术来解决这些问题。这些问题包括：1。通过使用日志结构，写缓冲体系结构的使用，解决了读写性能不对称的问题。2。通过在同一媒体量的同一媒体量的相关数据中，机械访问延迟的最小化，因为它是从本地存储中迁移的。这项研究将通过允许高性能访问大量存储来对当今日益增长的存储需求产生直接好处。在数据率远远超过访问速度的情况下，它解决了降低延迟的重要问题。它还通过减轻读写性能不对称的问题，可以有效地采用新兴的存储技术（例如磁光和体积全息图）。
