Researchers can purchase space on the service by filling out this form. For questions and support, email More details can be found on the Turbo Specifications page.


  • Turbo is available to researchers from any academic unit.
  • Turbo can be accessed from Mac OSX (Mavericks and Yosemite), Windows 7+, and Linux computers using NFSv, NFSv4 and CIFS.
  • Turbo space can be purchased in 1TB increments
  • Data on Turbo can be moved quickly and efficiently via the Globus File Transfer Service
  • Turbo provides the option of secure storage for regulated and/or sensitive data

Establish Service

See our Ordering Service page for details on how to request a Turbo volume.

Turbo costs $19.20 per terabyte per month, or $230.40 per terabyte per year, for replicated data. The cost for unreplicated data is $9.60 per terabyte per month, or $115.20 per terabyte per year. A U-M shortcode is required to order.

Permissions and Directories

When a volume is set up, the administrator associated with the account (i.e., specified by the Numeric User ID) will have full control to create directories and set permissions at the top level. This can be done with the standard Unix permission commands.

File Storage and Transfer

Accessing Turbo via CIFS

Turbo Research Storage CIFS volumes can be accessed at the following path:



For multi-protocol volumes, the UNC path is:

(e.g. \\\flux-support)


To connect using Windows or Mac clients:

1. Double click on the “My Computer” icon on your desktop.
2. Click on the “Tools” menu and then select “Map Network Drive…”
3. In the first drop down menu, select the drive letter for the drive mapping. Choose a letter that is not currently in use, and “after” the letter H, in order to avoid any conflicts with other drives. In the second box, type the path to the file server as provided above.
4. Make sure to place a check the “Reconnect at login” box. This option will remember your drive mapping next time you log in to your computer.
5. Click on the “Connect using a different user name” link underneath the “Reconnect at login” box and use the following settings:
• User Name: UMROOT\uniqname (substituting your actual uniqname for the word “uniqname”)
• Password: your UMICH Kerberos ( aka Level-1) password
6. Click the “OK” button.
7. Click the “Finish” button.

1. In the Finder, click on the “Go” menu and select “Connect to Server…”
2. In the “Server Address” field, type the server name and path: smb://
3. Click the “Connect” button.
4. When prompted, enter your uniqname and UMICH Kerberos ( aka Level-1) password.
5. Click the “Connect” button.


Globus, previously known as Globus Online, is a powerful and easy to use file transfer service that is useful for transferring files virtually anywhere. It is available for Turbo volumes that do not contain protected health information (ePHI).

For more information, please see our Globus File Transfer page.

Great Lakes users can use the Globus service or the Great Lakes transfer hosts.

Lost File Recovery

Turbo volumes that are configured with snapshots will save previous versions of files.  Only files which have been snap-shotted overnight are recoverable.  Files that are lost on the same day they were created may not be recoverable.

From Linux clients: To recover files lost from your directory, navigate to the .snapshot directory at the root of your share.

$ cd /nfs/turbo/flux-admin/.snapshot
$ ls -1

You can navigate to the snapshot directories and copy files back to your file share.
Note: The .snapshot directory may not be visible until you try enter it with cd.

From Windows clients, you can recover lost files from snapshots natively:

  • Open the directory that the deleted file was held in.
  • Right click in the directory that the file or folder was stored and select “Properties”.
  • Click on the “Previous Versions” tab when the Properties window opens.
  • A list of snapshots will be displayed.
  • Select the snapshot from which you wish to restore data.
  • In the new window, locate the file(s) you wish to restore.
  • Simply drag the file(s) or folder to their correct locations


Maintaining the overall stability of the system is paramount to us. System availability is based on our best efforts. We are staffed to provide support during normal business hours. We try very hard to provide support as broadly as possible, but cannot guarantee support on a 24 hour per day basis. Additionally, we perform system maintenance on a periodic basis, driven by the availability of software updates, staffing availability, and input from the user community. We do our best to schedule around your needs, but there will be times when the system is unavailable. For scheduled outages, we will announce them at least one month in advance on the ARC-TS home page; for unscheduled outages we will announce them as quickly as we can with as much detail as we have on that same page. You can also track ARC-TS at Twitter name ARC-TS.

Storage Resource Software

If you are unsure which of our storage services should be used to host your data, we have written some software that you can download and execute to analyze your files to understand how much of your data is stored in large files, how much of your data has been accessed recently, and the distribution of file sizes and access times. The software is accessible here

This software doesn’t examine the contents of any data files, it merely scans file attributes, it also does not store any file names after searching through the filesystem. 

If you have any questions on this software, please send us an email at with your inquiry.  If you are unsure about any of the recommendations the tool sends you, you should also contact us at with your inquiry.
