Data Transfer Nodes

The data transfer nodes are NERSC servers dedicated to performing transfers between NERSC data storage resources such as HPSS and the NERSC Global Filesystem (NGF), and storage resources at other sites including the Leadership Computing Facility at ORNL (Oak Ridge National Laboratory). These nodes are being managed (and monitored for performance) as part of a collaborative effort between ESnet, NERSC, and ORNL to enable high performance data movement over the high-bandwidth 10Gb ESnet wide-area network (WAN).
