Globus for Admins

By | | No Comments

ARC is a licensed subscriber for Globus that allows the entire University community to take advantage of enhanced features which include enabling Sharing or Guest collections on Personal and Server endpoints.

To enable sharing of an existing endpoint, ARC can add the endpoint to our management subscription. The system administrator or owner must email arcts-support@umich.edu to ask that the endpoint be put under the U-M subscription to enable sharing. Note that to be joined into the subscription the endpoint must be made public. After being added into the subscription, it can be set back to private if desired.

The request must include:

endpoint name = xxxx#yyyy , displayname or uid

Globus offers two distinct versions of the Connect Server v4 and v5, the procedures to install and configure each are considerable different.

GCS v4 is simpler and all file systems are behind a single endpoint:

To enable “Sharing” the system administrator should:

edit the configuration file at /etc/globus-connect-server.conf to set the following option:

[GridFTP] Sharing = True

review the configuration file for other relevant parameters (for example, consider setting “SharingRestrictPaths’ to restrict what users can share.

run GCS setup command again to read new configuration: # globus-connect-server-setup GCS v5 has enhanced management and control features that System Admins may want to take advantage of. These include but not limited to finer degree of separation of filesystems via what are called Gateways and Collections.  For example it may be beneficial to make available local file systems as a separate offering from network file systems. Configuration of GCS v5 is considerable more complicated and it is highly recommended that Systems Admin read and thoroughly understand all documentation before proceeding.

Transfer Data To and From Desktops/Laptops

By | | No Comments

There are two ways to transfer to and from desktops or laptops. Both can be used, but each is better suited to a range of numbers and sizes of files to transfer. Note that a browser is always involved via globus.org but you might have options as described below with rough recommended guidelines.

Small number of files or small sizes downloaded or uploaded:

Uploads – Once you have navigated to the remote storage Collection directory structure and it supports a direct browser upload you see an “Upload” button link in the center panel.

Downloads – Navigate to the remote storage and directy where the files are located. Highlight and choose download.

Many or large files:

Use Globus Connect Personal (GCP) which allows faster and more reliable transfers. GCP supports simple installation for Windows, Mac, and Linux computers.

If you have a need to share data from your desktop or laptop with research collaborators add “University of Michigan” as your Globus Plus Sponsor in your Globus Account Settings. Note: If possible use ARC provided servers to share data for performance and stability.

Please be sure you have your @umich.edu set as your contact email address in your profile. Note this is not required for normal Collections/Endpoints provided by ARC.

    1. Click on username menu top right
    2. Choose Globus Plus
    3. Choose get Globus Plus or if already a Plus member with another institution choose add another provider
    4. Find and click radio box for “University of Michigan” in the list. Advanced research computing will be notified of your request after clicking Continue

Once your request is approved, Globus Plus will allow you to create shared links to your own Globus Connect Personal client. These are also known as guest collections. Be advised, if you allow write access your local hard drive can be inadvertently filled.

If you intend to handle protected sensitive data please be sure read that section at the bottom if this document. You also need to have your personal endpoint our UMich HA (High Availability Sensitive Data) Subscription. At installation time choose the HA option and once endpoint is configured email us at arcts-support@umich.edu and include:

    1. Ask for your Personal endpoint be part of UMich HA subscription
    2. Provide Display Name and UUID of your endpoint

About Globus

By | | No Comments

Globus allows the transfer of data between different storage systems, lab computers, and personal desktops/laptops.

The standard features of Globus include:

  • Transfers faster than SCP/SFTP (usually by a factor of two)
  • Automatic restarts or continuation when transfers are disrupted
  • Background transfers so users need not remain logged in to a system
  • Transfers of large files between your laptop/desktop and servers via Global Connect Personal
  • Transfer of small number of small files between your laptop/desktop via a browser (note: not all server endpoints offer this feature)

U-M’s Globus Provider status adds the following features:

  • Sharing of server directories/folders with non-U-M collaborators who are also Globus users (for transfer/copy purposes, not shared use of server)
  • U-M signed BAA for High Assurance feature for sensitive data
  • Sharing of directories/folders from laptops/desktops via Globus Connect Personal clients and a Globus Plus account upgrade.
