Overview

Globus is a tool for users to request data transfers between predefined Globus sites (endpoints), or between an endpoint and a user desktop/laptop running Windows/Mac/Linux. Under the hood Globus uses GridFTP to do managed data transfers. Users do not need to know anything about GridFTP.

Usage

Globus is an online services that allows transferring data between different locations.  To use Globus you need to sign in. There are different options to sign in including creating an free account (Globus ID).

Once logged in, users can request data transfers, view progress on existing transfers, manage transfer requests and view history.

Globus Online also provides a python based command line interface. For installation and usage please refer to the CLI documentation.

The data transfer happens between two predefined Globus endpoints. The user will need to authenticate to both endpoints to pick data source and destination. The authentication generate tokens (grid proxies) with limited lifetime. They are stored at Globus for that user as substitutes of passwords, for both endpoints. When completed, a report will be sent to the user via e-mail.

If the data transfer is stopped because a user proxy has expired, one just needs to re-authenticate to renew the proxy.

One of the endpoints (but not both) can be a GlobusConnect running on user's destop/laptop. GlobusConnect is available for free download after login to Globus.

Globus Online endpoint at SLAC/LCLS

SLAC has several Globus Oline endpoints. One of them is for LCLS (slac#lcls). To be able to access Globus Online endpoint defined for LCLS, please send an email to data-management. Once a user is enabled to use Globus Online with LCLS, the user can authenticate with endpoint slac#lcls using SLAC unix username/password.
