MRI: Acquisition of PADS - A Petscale Active Data Store

Petascale活动数据存储（PADS）将是一个拍字节（1015字节）规模的在线存储服务器，能够持续千兆字节/秒的I/O性能，与9teraflop /s的计算资源和千兆字节/秒的局域网和广域网紧密集成。它的硬件和相关软件将使当地用户和国家科学界能够可靠地存储、访问和分析大量数据集。PADS的设计源于对天体物理学和天文学、计算机科学、经济学、进化和有机生物学、地球科学、高能物理学、语言学、材料科学、神经科学、心理学和社会学等领域参与小组的存储和分析需求的研究。对于这些小组来说，PADS代表了一个重要的机会，可以以新的方式查看他们的数据，从而实现新的科学见解。基础设施还将鼓励跨学科的新合作。PADS也是计算机科学研究进入主动数据存储系统的工具，并将为研究新技术提供丰富的数据。结果将作为开源软件提供。

The Petascale Active Data Store (PADS) will be a petabyte (1015-byte)-scale online storage server capable of sustained multi-gigabyte/s I/O performance, tightly integrated with a 9 teraflop/s computing resource and multi-gigabit/s local and wide area networks. Its hardware and associated software will enable the reliable storage of, access to, and analysis of massive datasets by both local users and the national scientific community.The PADS design results from a study of the storage and analysis requirements of participating groups in astrophysics and astronomy, computer science, economics, evolutionary and organismal biology, geosciences, high-energy physics, linguistics, materials science, neuroscience, psychology, and sociology. For these groups, PADS represents a significant opportunity to look at their data in new ways, enabling new scientific insights. The infrastructure also will encourage new collaborations across disciplines. PADS is also a vehicle for computer science research into active data store systems, and will provide rich data on which to investigate new techniques. Results will be made available as open source software.
