What is REDDnet?

REDDnet (Research and Education Data Depot network) is an NSF-funded data collaboration project. We have deployed an extremely large (>700 Terabytes) distributed storage facility with a core focus of speed and fault tolerance. For example, at the Supercomputing 2006 Conference in Tampa, Florida, REDDnet demonstrated sustained transfers at a rate of 10 Gigabits per second between Caltech and the convention floor. These transfers were limited by the bandwidth of the network connection. At the same conference, REDDnet demonstrated fault tolerance by striping data across thirty depots and then successfully reading the data even after turning off nine of these depots.
