ALICE Data Transfer Server

From ALICE Documentation

There are many ways to transfer data on ALICE. The one you choose will depend on your file size, its source location, and convenience. A secure shell (SSH, SFTP) is required when connecting to an HPC head node to transfer data.

sftp-gw.alice.universiteitleiden.nl u is a dedicated high-speed data transfer head node, running on the Linux operating system, with 10-gigabit network connections to the public Internet and the ALICE private network. The ALICE Data Transfer Server is used solely for data transfers. Job submissions and other standard head node activities are not provided on this data transfer node. For job submissions and compiling, please utilize one of the standard head nodes.

Please keep in mind that the Data Transfer Server is a shared resource. If you launch too many processes and these processes negatively impact either the data transfer server or the shared file system, your processes will be terminated.

Instructions for transferring your data to the Data Transfer Server using scp or sftp can be found on the File Transfer page.

Note: Additional settings are required to use the Data Transfer Server with Filezilla. Use the Site Manager to create a new connection or edit existing settings for the Data Transfer Server.

  • General tab: select “Interactive” for “Login Type”
  • Transfer Settings tab: check “Limit number of simultaneous connections”

The Transfer Settings options will prevent you from having to authenticate again once the session is established.
