Oak Ridge National Laboratory Tests the Limits of Long-Haul InfiniBand over UltraScienceNet using Obsidian Longbow Range Extenders
"Using InfiniBand's Remote Direct Memory Access (RDMA), we found we could stream data across all 8,600 miles of USN with an essentially flat bandwidth-distance curve, right out of the box. To see this kind of plug-and-play performance with no in-situ tuning, and independent of distance, is in striking contrast to normal network performance"
