Globus 

Globus is a service which provides a set of tools to facilitate parallel, load-balanced, fault tolerant data transfers; these tools can be used to transfer, share and/or publish data.  CHPC licenses these services and provides dedicated data transfer nodes

Setup of Globus for File Transfers using the CHPC Data Transfer Nodes in the General Environment

  • Create a Globus account at: https://www.globus.org/ or you can use the "alternate login" and use your institutes identity provider & authenticate appropriately. 
  • Log in to your newly created Globus account.
  • Under "Quick Links" select "Transfer Files." You will be directed to a page with a look similar to the WinSCP interface.
  • Log in to an endpoint on each side of the interface: one side being the source and the other the destination.  
  • Next to the "Endpoint" box, click the "..." botton for a list of all possible endpoints. CHPC currently offers several public endpoints:

                         uofuchpc#dtn01 (single server attached at 40gbps)

                         uofuchpc#dtn02 (clustered endpoint consisting of 4 servers each attached at 40gbps)

                         uofuchpc#dtn04 (single server connected at 10gbps)

  • In most cases, users must authenticate to activate an endpoint. There are a few different possible authentication methods, but the most commonly used are either the organization authentication method or a federated authentication. The endpoints offered by CHPC use either uNID and campus password directly for authentication, or the InCommon federated authentication, which merely redirects users through the InCommon webpage to the U's CAS page to enter username and password.
  • Once authenticated, choose the desired files and/or directories and click the appropriate directional arrow button to start the transfer.
  • As the transfer is proceeding, click the "Activity" button and select your transfer and monitor progress. When the transfer completes, you will receive an email notifying you it is done and giving you statistics of the transfer.

Setup of Globus for File Transfers using the CHPC Data Transfer Nodes in the Protected Environment

In the protected environment, there is a newer version of Globus (GCSv5) running on the PE DTNs, pe-dtn01 and pe-dtn02, along with the Globus high assurance (HA) which enable the use of globus with PHI data. 

In order to use:

  • Login to www.globus.org
  • Open file manager on the upper left side.
  • Type “chpc pe” in the collection field and select one of the following  (you may need to re-auth & two factor depending on when you last did that in your browser session
    • University of Utah - CHPC PE-DTN01
    • University of Utah - CHPC PE-DTN02
  • Now one can use file manager in  single or double panel view (this is in upper right).

Use of Globus to access CHPC Pando Archive Storage

As an alternative to using rclone, globus is a feature-rich way to interact with the archive storage.  We have created a clustered Globus endpoint specifically for PANDO.  Note that the globus ceph plugin is a beta product still being developed by the globus team and therefore if you experience any issues or have any comments about the tool, please assist us and the globus team by providing feedback.

Steps to use:

  1. Navigate to the Globus web page.
  2. Log in using “existing organizational login”
  3. Pick “University of Utah” from the list.
  4. Authenticate using your campus ID and password.  
  5. The name of the Endpoint is “University of Utah - CHPC PANDO Archive"

Globus will automatically query the archive and obtain your access and secret keys and you will be brought to the top level bucket of your portion of the archive storage.

 

Use of Globus with the Command Line Interface (CLI)

Globus has a Command Line Interface (CLI) allowing users access to Globus from the shell.  The Globus CLI requires its own installation and is a standalone, open source application.
