To move amounts less than 10GB, you can go through the login nodes. These are the only Niagara login nodes visible from outside Niagara. You can use scp or rsync to niagara.scinet.utoronto.ca or niagara.computecanada.ca (there is no difference). Transfers done in this way will time out for amounts larger than about 10GB. | *To move amounts less than 10GB, you can go through the login nodes.

To move amounts of data larger than 10GB, you should go through the datamover node. Datamover nodes are not reachable from the outside, so to do so, from a Niagara login node, first ssh into <code>nia-dm1</code> or <code>nia-dm2</code>, and initiate transfer from the datamovers. | *To move amounts of data larger than 10GB, you should go through the datamover node.
