Design of a Large Capacity Object Server Supporting Earth System Science Researchers

本研究旨在为与海洋、陆地和大气的物理相互作用有关的全球气候变化科学研究中遇到的各种数据类型量身定制高容量存储和相关对象管理系统的I/O子系统。研究人员正在构建一个原型系统，用真实数据填充它，并将其提供给国家研究和教育网络（NREN）上的地球系统科学研究人员。原型对象管理系统基于可扩展数据库系统（POSTGRES）和廉价磁盘冗余阵列（RAID）这两种技术的重要扩展，这两种技术部分是在以前的NSF支持下开发的。本研究涉及数字设备公司bbbbs （DEC）项目红杉2000。DEC为这项资助下的研究人员提供了进行研究所需的设备。

This research is to design I/O subsystems for high capacity storage and associated object management systems tailored for the kinds of data types encountered in scientific research on global climate change related to the physical interaction of the ocean, land and atmosphere. The researchers are constructing a prototype system, populating it with real data and making it available to earth system science researchers on the National Research and Education Network (NREN). The prototype object management system is based on significant extensions of the dual technologies of extensible database systems (POSTGRES) and redundant arrays of inexpensive disks (RAID), developed in part under previous NSF support. This research relates to Digital Equipment Corporation>s (DEC) project Sequoia 2000. DEC has provided the researchers funded under this grant with the equipment necessary to perform the research.
