For the second year in a row, the Pacific Northwest National Laboratory demonstrated its computational storage capabilities at the annual supercomputing conference. The PNNL team streamed video data from high-capacity storage on the conference show floor to Hewlett-Packard-loaned hardware in the lab's booth. The amount of data moved ranged from 30 to 60 gigabits per second. At the low end, this is the equivalent of transferring and processing a full DVD of video every second. This direct access to data on parallel file systems across high-speed wide area links was made possible by recent network bandwidth increases at PNNL, including new fiber optic connections to Richland and a connection to the Department of Energy's UltraScience Net exchange in Seattle. UltraScience Net provides on-demand dedicated bandwidth channels at multi, single and sub lambda resolutions. PNNL used six dedicated 10 gigabit lambdas to transfer data from an HP StorageWorks Scalable File Share parallel file system to an Itanium cluster located more than 250 miles away. Following processing, the resulting data set was written back to the storage cluster
