CC-NIE Integration: Bringing SDN based Private Cloud to University Research

大学校园中的科学计算小组经常受到以灵活且经济高效的方式访问计算周期、存储容量和网络带宽不足的限制。这阻止了他们扩展其应用程序和承担重大挑战问题。此外，目前的网络基础设施是使用专有交换机、路由器以及防火墙和负载均衡器等不断增加的设备构建的。因此，IT运营团队面临着日益增长的复杂性、成本和对现有基础设施的失控。这种封闭的基础设施也阻止了网络研究人员在生产环境中大规模探索新想法。该项目利用了Web基础设施和“云”正在利用的两项颠覆性技术：多租户虚拟集群和软件定义网络(SDN)。多租户虚拟群集支持具有非常灵活的资源使用和最佳性价比的横向扩展设计。SDN使定制基础设施成为可能，并消除了不必要的复杂性和成本。该项目构建了一个基于SDN的私有云，将这两种颠覆性技术带到园区，并随之而来的是规模、灵活性和成本效益。有了这种私有云，科学计算团队能够共享物理基础设施，同时为其应用程序定制计算和网络。以雷达遥感和生物计算应用为例，展示了该基础设施的价值。基于SDN的私有云将影响校园中的各个社区，并将成为其他校园的展示窗口，从而帮助它们利用网络和计算的最新趋势。

Scientific computing groups on university campuses are often limited by insufficient access to computing cycles, storage capacity, and network bandwidth in a flexible and cost effective way. This prevents them from scaling their applications and taking on grand-challenge problems. Moreover, the current network infrastructure is built with proprietary switches, routers and with proliferating appliances such as firewalls and load balancers. As a result, the IT operation group faces increasing complexity, cost, and lack of control of the existing infrastructure. This closed infrastructure also prevents network researchers from exploring new ideas at scale in a production setting.This project leverages two disruptive technologies that the Web infrastructure and "a cloud" are exploiting: multi-tenancy virtualized clusters and Software Defined Networks (SDN). Multi-tenancy virtualized clusters enable scale-out designs with very flexible resource use and the best cost performance. SDN makes it possible to customize infrastructure and to eliminate unnecessary complexity and costs.This project builds an SDN-based Private Cloud to bring these two disruptive technologies to the campus and with them the scale, flexibility, and cost performance. With this private cloud, scientific computing groups are able to share the physical infrastructure while simultaneously customizing computing and networking for their applications. Radar remote sensing and biological computing applications are used as example scientific computing applications to demonstrate value of this infrastructure. The SDN based Private Cloud will impact various communities on a campus and will become a showcase for other campuses and thus help them exploit the latest trends in networking and computing.
