To copy large data to/from ZIH systems, the so-called
**export nodes**
should be used. While it is
possible to transfer small files directly via the login nodes, they are not intended to be used that
way. Furthermore, longer transfers will hit the CPU time limit on the login nodes, i.e. the process
get killed.
The export nodes have a better uplink (10 GBit/s) allowing higher bandwith.
Note
that
you cannot log in via SSH to the export nodes, but only use
`scp`
,
`rsync`
or
`sftp`
on them.
