Using Turbo

Turbo is a high-capacity, fast, reliable and secure data storage service for researchers across U-M. Turbo is configured to be easily sharable with on-campus resources such as the Flux HPC cluster, as well as off-campus systems and collaborators. Researchers can purchase space on the service by filling out this form. For questions and support, email hpc-storage@umich.edu. More details can be found on the Turbo Specifications page.

Features

  • 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 NFSv3 and NFSv4
  • Turbo space can be purchased in 1TB increments
  • Turbo uses the Globus File Transfer Service
  • Turbo provides the option of secure storage for regulated and/or sensitive data
  • Turbo allows optional daily snapshots and backups of stored research 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.

For assistance with permissions, email hpc-support@umich.edu.

File Storage and Transfer

Globus

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.

Flux users can use the Globus service or the Flux 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
daily_2015-08-24-_23-30
daily_2015-08-25-_23-30
daily_2015-08-26-_23-30
daily_2015-08-27-_23-30
daily_2015-08-28-_23-30
daily_2015-08-29-_23-30
daily_2015-08-30-_23-30

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

Policies

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.
