CC-NIE Network Infrastructure: PRISM@UCSD: A Researcher Defined 10 and 40Gbit/s Campus Scale Data Carrier

PRISM@UCSD创建了一条覆盖全校范围的由下一代Arista交换机路由的高带宽端到端光纤连接组成的“大数据高速公路”。这创建了一个聚合带宽超过10 TB/S的光纤交换矩阵，具有类似于机房群集的全等分，但部署在园区规模。这个由研究人员定义的网络将基因组测序仪和显微镜等实验室内科学仪器的用户与远程计算、可视化、数据存储和分析系统联系在一起。PRISM通过向一组目标数据密集型实验室提供补充、专门、经济高效的大容量网络，来桥接、增强和保护现有园区生产网络。PRISM建立在Quartzite“校园规模网络实验室”NSF MRI(2006年获奖)的基础上，并对其进行了升级，该MRI是由具有极端规模带宽要求的应用程序推动的。与Quartzite相比，Prism不仅通过OpenFlow增加了IPv6功能和对软件定义网络的支持，还将端口容量增加了4倍，功耗降低了3倍，并消除了核心交换机上所有卡到交换机背板的过度订阅。此外，到圣地亚哥超级计算机中心的现有光纤连接正在扩展到120Gbps，作为通向云/并行存储和NSF XSEDE资源的高带宽桥梁。这从根本上使包括物理、化学、生物、气候变化、海洋学和计算机科学在内的多个学科的研究能够应对大数据挑战。工作室将与区域光纤网络和EDUCAUSE一起举办，以向研究校园传播经验，并充分描述这种具有成本效益、可扩展和可复制的基础设施。此外，针对少数群体服务机构的夏季讲习班将在CALIT2/SDSC多样性外联传统的基础上发展。棱镜将为其他国家建立自己的大数据交通系统提供借鉴。

Prism@UCSD creates a campus-wide "Big Data freeway" composed of high-bandwidth end-to-end optical connections routed by a next-generation Arista switch. This creates an optical fabric capable of more than 10 Terabit/s of aggregate bandwidth, has full bisection similar to in-machine room clusters but is deployed at a campus scale. This researcher-defined network unites users of in-lab scientific instruments such as genome sequencers and microscopes with remote compute, visualization, data-storage and analysis systems. Prism bridges to, augments, and protects the existing campus production network by providing a complementary, specialized, cost-effective, massive-capacity network to a targeted group of data-intensive labs. Prism builds upon and upgrades the Quartzite "campus-scale network laboratory" NSF MRI (awarded 2006) that was motivated by applications with extreme-scale bandwidth requirements. Compared to Quartzite, Prism not only adds IPv6 capability and support for software defined networks via OpenFlow, but also increases port capacity by 4x, lowers power consumption by 3x, and removes all card-to-switch-backplane over-subscription at the core switch. In addition, the existing optical fiber connection to the San Diego Supercomputer Center is being expanded to 120Gbps as a high-bandwidth bridge to cloud/parallel storage and NSF XSEDE resources. This fundamentally enables research in multiple disciplines, including physics, chemistry, biology, climate change, oceanography, and computer science to address big-data challenges.Workshops will be held with regional optical networks and EDUCAUSE to disseminate experience to research campuses and fully describe this cost-effective, expandable and replicable infrastructure. In addition, a summer workshop aimed at minority serving institutions will build on Calit2 / SDSC's tradition of diversity outreach. Prism will form a model for others to follow in building their own big-data transportation systems.
