Career Personal Terabyte Disk Managing

项目摘要

Magnetic disk drives are expected to increase in capacity and drop in price at a rate of over 50% per year for at least a decade. By 2010, a terabyte of magnetic disk storage for personal computers will cost a few hundred dollars. The Personal Terabyte Project is developing a set of tools for managing and exploiting this large personal data repository. To guarantee reliability of personal terabyte data, backup techniques including compression, incremental backups, and selective backups of essential data will be implemented, as will disk array redundancy techniques. Future homes will have a variety of network connections, from high-bandwidth, inexpensive broadcast connections to higher-cost, lower-bandwidth point-to-point links. The personal terabyte will cache relevant data that arrives on broadcast networks and aggressively prefetch additional data over point-to-point, on-demand connections. As data are stored on the personal terabyte, the toolkit will perform automatic indexing of text, images and video to facilitate finding data on the massive file system. To address the gap between memory and disk access times, the toolkit will prefetch data from disk to main memory. Finally, to improve application performance, the toolkit will facilitate sharing of the disk cache among local and remote processes.***

磁盘驱动器预计在至少十年内以每年超过50%的速度增加容量并降低价格。到2010年，个人电脑的百万兆字节磁盘存储将花费几百美元。个人太字节项目正在开发一套工具，用于管理和利用这一大型个人数据储存库。为了保证个人TB数据的可靠性，将实施包括压缩、增量备份和基本数据的选择性备份在内的备份技术，以及磁盘阵列冗余技术。未来的家庭将有各种各样的网络连接，从高带宽、便宜的广播连接到高成本、低带宽的点对点连接。个人TB将缓存到达广播网络的相关数据，并通过点对点、按需连接主动预取额外数据。由于数据存储在个人TB上，该工具包将对文本、图像和视频进行自动索引，以方便在庞大的文件系统中查找数据。为了解决内存和磁盘访问时间之间的差距，工具包将从磁盘预取数据到主存。最后，为了提高应用程序性能，该工具包将促进本地和远程进程之间的磁盘缓存共享。*
