CC* Networking Infrastructure: Integrating Big Data Instrumentation into Campus Cyberinfrastructure

数据密集型科学仪器的快速发展已经大大超过了校园网络基础设施的能力，可以有效地将大数据生产设施连接到强大的计算和存储系统。这延误了对大量有价值的科学数据的分析、使用和传播，从而影响了多个科学和工程领域的发现和创新。普渡大学的项目通过改善五个大数据仪器设施和中央支持的网络基础设施（CI）之间的校园高速网络基础设施来弥合这一差距，其中包括超级计算机，大型存储系统和校园外的网络连接。这些设施支持加速新材料的研究，了解大脑功能和病毒，监测低层大气天气，在教学和公众参与中使用地理空间数据，以及安全计算。该项目建立在校园信息技术专家和领域科学家之间强大的伙伴关系基础上。该项目为五个选定的大数据设施增加了高速科学DMZ连接，使大容量、高速或交互式科学数据流能够流向校园研究网络基础设施和校外设施。分布层的现有Cisco Nexus 7710网络交换机通过新的40千兆网络模块得到增强，将带宽提高到每秒20-80千兆比特。这将大大提高研究生产力，并通过更快的数据传输、更容易进入中央计算基础设施，更有效地利用普渡大学的100-该奖项反映了NSF的法定使命，并通过使用基金会的知识产权进行评估，优点和更广泛的影响审查标准。

Rapid advancements in data-intensive scientific instrumentation have greatly outpaced the capability of campus networking infrastructures to effectively connect big data-producing facilities to powerful computing and storage systems. This delays the analysis, use and dissemination of a huge amount of valuable scientific data for discovery and innovation in multiple science and engineering domains. Purdue's project bridges this gap by improving the campus high-speed network infrastructure between five big data instrument facilities and the centrally supported cyberinfrastructure (CI) consisting of supercomputers, large storage systems and network connections to outside the campus. The facilities support accelerated research in new materials, understanding brain functions and viruses, monitoring lower atmospheric weather, employing geospatial data in teaching and public engagement, and secure computing. The project builds upon a strong partnership between campus information technology experts and domain scientists. It also helps prepare the next generation of CI professionals by pairing student workers with the campus CI experts.The project adds high-speed Science DMZ connections to the five selected big data facilities enabling high-volume, high-velocity, or interactive science data flows to both the campus research cyberinfrastructure and off campus facilities. Existing Cisco Nexus 7710 network switches at the distribution layer are augmented with new 40-Gigabit networking modules, increasing bandwidth to 20-80 Gigabits per second. This should yield a significant increase in research productivity, and more timely publication and dissemination of research data and results, through faster data transfer, easier access to the central computing infrastructure, and more effectively utilizing Purdue's 100-Gigabit WAN connections and research network peerings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
