CC-NIE Network Infrastructure: Implementation of a Science DMZ at San Diego State University to Facilitate High-Performance Data Transfer for Scientific Applications

圣地亚哥州立大学（SDSU）的CC-NIE网络基础设施项目正在构建和部署一个科学DMZ，以支持数据密集型科学，并适应SDSU与其他大学和国家实验室之间的特定端到端数据流。 科学DMZ的设计遵循能源科学网络（ESnet）的愿景和架构。 部署Cisco Nexus 7000和2000系列交换机，沿着10 Gbps连接到CalREN-HP网络，供Science DMZ专用。 SDSU的研究人员正在直接连接到Nexus交换机的Lustreparallel文件系统上托管延迟敏感的应用程序和数据集。 这些应用程序和数据集支持地震破裂和波传播的数值模拟、沿海海洋建模、脉冲爆震发动机、玻色-爱因斯坦凝聚物中的涡环以及蛋白质组学、基因启动子生物信息学和微生物宏基因组学的大规模数据等研究项目。 该项目将直接影响包括计算科学研究中心的教师和学生，该中心吸引了SDSU所有科学和工程部门的参与。 科学DMZ为研究人员提供了快速交换大型数据集和部署基于Web的科学应用程序的能力，这些应用程序可以通过专用网络访问，该专用网络与校园人口产生的一般互联网流量分开，因此不受其影响。 DMZ将促进SDSU计算资源的远程使用，培养与更广泛的科学界共享数据的协作工具的开发，建立新的研究伙伴关系，并在从事计算科学的教师和学生之间培养新的导师机会。

The CC-NIE Network Infrastructure project at San Diego State University(SDSU) is constructing and deploying a Science DMZ to support dataintensive science and accommodate specific end-to-end dataflow scenariosbetween SDSU and other universities and national laboratories. Thedesign of the Science DMZ follows the vision and architecture laid outby the Energy Sciences Network (ESnet). Cisco Nexus 7000 and 2000series switches are deployed, along with a 10Gbps connection to theCalREN-HP network with exclusive use by the Science DMZ. Researchers atSDSU are hosting delay-sensitive applications and datasets on Lustreparallel file systems directly attached to the Nexus switches. Theseapplications and datasets support research projects in the numericalsimulation of earthquake rupture and wave propagation, coastal oceanmodeling, pulse detonation engines, vortex rings in Bose-Einsteincondensates, and large-scale data for proteomics, gene promoterbioinformatics, and microbial metagenomics. The project will directlyimpact the faculty and students who encompass the Computational ScienceResearch Center which draws participation from all science andengineering departments at SDSU. The Science DMZ provides researcherswith the capability to rapidly exchange large datasets and deployWeb-based science applications that are accessible through a dedicatednetwork that is separate from, and therefore not impacted by, generalInternet traffic generated by the campus population. The DMZ willpromote remote usage of computing resources at SDSU, cultivatedevelopment of collaborative tools for sharing data with the broaderscientific community, establish new research partnerships, and fosternew mentorship opportunities between faculty and students engaged incomputational science.
