dc.description.abstract Digital instruments and simulations are creating an ever-increasing amount of data. The need for institutions to acquire these data and transfer them for analysis, visualization, and archiving is growing as well. In parallel, networking technology is evolving, but at a much slower rate than our ability to create and store data. Single fiber 100 Gbps networking solutions are soon to be deployed as national infrastructure. This article describes our experiences with data movement and video conferencing across a networking testbed, using the first commercially available single fiber 100 Gbps technology. The testbed is unique in its ability to be configured for a total length of 60, 200, or 400 km, allowing for tests with varying network latency. We performed low-level TCP tests and were able to use more than 99.9% of the theoretical available bandwidth with minimal tuning efforts. We used the Lustre file system to simulate how end users would interact with a remote file system over such a high performance link. We were able to use 94.4% of the theoretical available bandwidth with a standard file system benchmark, essentially saturating the wide area network. Finally, we performed tests with H.323 video conferencing hardware and Quality of service (QoS) settings, showing that the link can reliably carry a full high-definition stream. Overall, we demonstrated the practicality of 100 Gbps networking and Lustre as excellent tools for data management. en
dc.description.sponsorship ndiana University’s participation in this project was supported in part and enabled by a variety of NSF grants to Indiana University: 0521433 [43], which funded IU’s initial experiments with Lustre; and 0504075 [44] and 0932251 (subcontract from University of Chicago [45]), which funded expansion and use of IU’s Lustre-WAN within the TeraGrid. This work leverages IU’s leadership of the FutureGrid project (NSF0910812 [46]), which facilitates research on grid projects generally. IU’s participation in this project was facilitated and supported by a grant from the Lilly Endowment to create the Indiana University Pervasive Technology Institute [13].The time and effort of Thomas William on this project was funded via a contract with IU. The videoconferencing tests were performed by Christian Meyer of the Competence Centre for Video Conference Services (VCC). The VCC is funded by the National Research and Education Network of Germany (DFN). This project was carried out under the auspices of a Memorandum of Friendship and Collaboration between the Office of the Vice President for Information Technology at IU and ZIH at TU Dresden. en
