MRI: Acquisition of a High-Speed, High Capacity Storage System to Support Scientific Computing: The Data Capacitor

这个项目创建了一个数据电容器和一个元数据/Web服务服务器，解决了两个明显而广泛的挑战：需要在短时间内(几小时到几天)存储和处理大量数据，以及通过Web可靠和明确地发布、发现和利用数据。数据电容器是一个250 TB的短期数据存储，具有非常快的I/O，元数据/Web服务服务器是一个强大的服务器，使机构和合作者能够采用和依赖Web服务来交换研究数据。伊利诺伊大学的研究和开发工作将创造出充分利用数据电容器所需的工具。由先进的数字仪器如此迅速地产生的大量数据已经从根本上改变了许多学科的进展和研究可能性。科学家目前面临的挑战是从这些数据中提取其中包含的信息和意义。印第安纳大学建立了一个重要的网络基础设施，由高性能计算系统、档案存储系统和先进的可视化系统组成，横跨印第安纳波利斯和布鲁明顿两个主要校园，并连接到国家和国际网络。该机构加强其基础设施的方式将导致大量使用大型数据集的科学家的研究能力和发现机会发生质的变化。数据电容器有望成为新的网络基础设施的开发平台和试验台，以及大容量短期存储设备的概念验证。另一方面，元数据/Web服务服务器使该机构能够在许多领域建立基于标准的数据传播的领导地位。广泛的影响：数据电容器增强了相关科学社区的当前实践，使技术转移和商业化成为可能，培养了21世纪的劳动力，并确保公众理解科学的价值。在所有具有更广泛影响的领域刻意使用客观指标，确保新的发现、技术发展、教育活动和公共信息努力转化为科学界和整个社会的利益。妇女和代表不足的群体将被吸引到计算密集型科学和计算应用领域。

This project, creating a Data Capacitor and a Metadata/Web Services server, addresses two clear and widespread challenges: the need -To store and manipulate large amounts of data for short periods of time (hours to several days) and-For Reliable and unambiguous publication, discovery, and utilization of data via the Web.The Data Capacitor, a 250 Terabyte short term data store with very fast I/O and the Metadata/Web Services server, a robust server, enable the institution and collaborators to adopt and depend upon the Web services for exchange of research data. Research and development efforts at IU will create the tools required for the Data Capacitor to be used to its fullest. Progress and research possibilities in many disciplines have been fundamentally changed by the abundance of data now so rapidly produced by advanced digital instruments. Scientists face the present challenge of drawing out from these data the information and meaning contained within. IU has established a significant cyberinfrastructure composed of high performance computing systems, archival storage systems, and advanced visualization systems spanning two main campuses in Indianapolis and Bloomington, and connected to national and international networks. This institution enhances its infrastructure in ways that will result in qualitative changes in the research capabilities and discovery opportunities of a broad array of scientist that work with large data sets. The Data Capacitor is expected to become a development platform and testbed for new cyberinfrastructure, as well as a proof of concept for large capacity, short-term storage devices. On the other hand, the Metadata/Web Services server enables the institution to establish a leadership position in standards-based data dissemination in many fields.Broader Impact: The Data Capacitor enhances current practice in relevant scientific communities, enables technology transfer and commercialization, develops a 21st century workforce, and ensures public understanding of the value of science. Deliberate use of objective metrics in all areas of broader impact ensures that new discoveries, technology development, educational activities, and public information efforts translate into benefit for the scientific community and society as a whole. Women and underrepresented groups will be drawn into computing-intensive sciences and applications of computing.
