CC* Storage: The South Dakota Data Store, a Modular, Affordable Platform to Enable Data-Intensive Research and Education

数据驱动型研究的机会越来越多，赞助研究中对数据管理的要求也越来越高，这导致了对不经常访问的长期档案数据集以及定期访问以重新访问、修订和共享实验结果的“活动档案”数据的保留的需求日益增长。对于这个项目，南达科他大学将获得、部署和维护南达科他州数据存储(SDDS)，这是一种可通过网络访问、可共享的多校园存储资源，与现有的校园网络基础设施集成在一起。最初，SDDS将支持南达科他州四所院校八个系的十二个STEM项目，包括30名教职员工、43名博士后和303名学生。SDDS将为南达科他州的研究人员提供一个集中、高效、高性能的平台，用于对大量电子数据进行存档和共享访问。SDDS包括两项主要服务。共享层为需要持续访问大量数据的研究提供高可靠性、高可用性、可通过网络访问的存储。归档层提供长期的异地归档级存储。SDDS将为南达科他大学的所有教职员工、博士后、学生和研究生提供服务。通过多个机构的合作，SDDS还将为南达科他州立大学、黑山州立大学和南达科他州矿业与技术学院的研究人员提供服务，所有教育和非营利性非商业研究人员都可以进一步在社区采用SDDS。该项目利用了南达科他州大学和南达科他州州立大学在专门的科学非军事区网络中的先前投资。所有参与者将能够通过现有的10 Gb连接访问SDDS，并使用所有相关机构的现有PerfSONAR部署确保端到端性能测量。

Expanding opportunities for data-driven research and increasing requirements for data management in sponsored research have resulted in a growing need for retention of both long-term archival data sets that are infrequently accessed, as well as 'active archives' of data that are accessed periodically to revisit, revise, and share experimental results. For this project, the University of South Dakota will acquire, deploy, and maintain the South Dakota Data Store (SDDS), a network-accessible, sharable, multi-campus storage resource integrated with existing campus cyberinfrastructure. Initially, SDDS will support twelve STEM projects across eight departments at four institutions in South Dakota, including 30 faculty, 43 postdocs, and 303 students. SDDS will provide South Dakota researchers with a centralized, efficient, high-performance platform for both archival of and shared access to large quantities of electronic data. SDDS includes two major services. The Sharing Tier provides high-reliability, high-availability, network-accessible storage for research requiring persistent access to large quantities of data. The Archival Tier provides long-term offsite archival-grade storage. SDDS will serve all faculty, staff, postdocs, students, and graduate students at the University of South Dakota. Through a partnership of multiple institutions, SDDS will also serve researchers at South Dakota State University, Black Hills State University, and the South Dakota School of Mines and Technology, with access open to further community adoption by all educational and not-for-profit noncommercial researchers. The project leverages prior investments at the University of South Dakota and South Dakota State University in dedicated Science DMZ networks. All participants will be able to access SDDS via existing 10Gb connectivity, and end-to-end performance measurement is ensured using existing PerfSONAR deployments at all involved institutions.
