Data Transfer Nodes (DTNs)¶
The Data Transfer Nodes (“DTNs”;
dtn.ccs.ornl.gov) are hosts specifically
designed to provide optimized data transfer between OLCF systems and systems
outside of the OLCF network. These nodes perform well on local-area transfers
as well as the wide-area data transfers for which they are tuned. The OLCF
recommends that users use these nodes to improve transfer speed and reduce load
on computational systems’ login and service nodes.
