The Data Reservoir project's goal is to create a global grid infrastructure for scientific disciplines, to enable distributed data sharing and high-speed computing for data analysis and numerical simulations. At the center of this infrastructure is the 2-PFLOPS system being developed as part of the GRAPE-DR project, to be operational in 2008.
At iGrid, storage services that use the GRAPE-DR's single-box high-density 10Gb storage server and an IPv6 fast TCP data transfer protocol demonstrate, for the first time, 10Gb TCP utilization in a production environment. By using "inter-layer coordination optimization" for TCP on both IPv4 and IPv6, 10Gb storage services can be realized using only a few TCP streams, providing new opportunities for large-scale data sharing. This project receives funding from the Special Coordination Fund for Promoting Science and Technology, MEXT, Japan.

Note:
On November 14, 2005, this group won the Internet2 Land Speed Records (I2-LSR) in both the IPv6 single-stream and IPv6 multi-stream categories. The team from the University of Tokyo, the WIDE Project, and Chelsio Communications successfully transferred data at a rate of 5.58 Gbps over a distance of over 30,000 kilometers traversing the WIDE, IEEAF, JGN2 networks. Achieving 167,400 terabit-meters per second (Tb-m/s), the team more than doubled the existing record, surpassing it by 131 percent.
"Data Reservoir on very-long-distance IPv6/IPv4 network" received the SC|05 Bandwidth Challenge award for "Fastest IPv6." They achieved 6.84Gbps peak traffic on IPv6.
