RStor - Central Data Storage for Researchers

RStor is Research Computing's data storage offering.  It is available to anyone in the Dartmouth community.  RStor is based on the OpenAFS distributed filesystem which provides secure network file storage at relatively low cost.  RStor is frequently used to share files across the Internet because it has strong authentication and flexible access control.  This can be especially useful to researchers when they either need off campus access themselves or the ability to share data with non-Dartmouth collaborators.

Mac, Windows, and Linux users can directly access RStor by installing the OpenAFS client.  The Research Computing compute servers, Polaris and Andes, already have the OpenAFS client installed and use RStor for home directories.  This means it is also possible to access RStor using an SFTP client to connect to Polaris or Andes.

Available Storage

Faculty, staff, and graduate students each receive a default allocation of 20GB for their home directories when applying for accounts on Polaris and Andes. Undergraduate students receive a default allocation of 10GB.  

Additional storage for large research data collections, up to 2TB per volume (multiple volumes are okay), is available on a hardware cost-recovery basis.  As of April 2013, the rate is $180 per terabyte per year for a replicated volume (2 copies).  Smaller volumes are prorated - e.g. 100GB is approx $18 per year.

Choosing between the OpenAFS client and SFTP

The OpenAFS client actually mounts your RStor space on your computer so you can use files directly out of RStor.  It's similar to attaching a USB drive in that sense (except you obviously need a network connection instead of a USB cable).

SFTP clients are somewhat simpler to install but you have to manually transfer files back and forth to use them on your computer.
