Abstract

Modern nuclear and high energy physics experiments yield large amounts of data and thus require efficient and high capacity storage and transfer. BNL, the hosting site for RHIC experiments and the US ATLAS Tier 1 Center, plays a pivotal role in transferring between other sites in the US and around the world for data distribution and processing. Each component in the infrastructure from data acquisition system to local analysis facility must be tuned, tested, monitored, and sometimes diagnosed to transfer such a massive volume of data, often over long distances. Maximal performance can be reached by performing a combination of hardware optimization, TCP tuning, transfer application tuning and network architecture optimization.
