Data Management

Data Storage, Backup and Archiving

The Center for Computation and Visualization (CCV) at Brown University provides storage for large research files. A default allocation of 256 GB (also called Rdata) is given to all faculty members at Brown, on a per request basis, with the option of purchasing additional storage as needed. Long term storage and backups are available on a fee basis. Storage can be purchased in increments of terabytes for periods of 6 years, the cost for backups is included when storage is purchased.  Data is incrementally backed up to tape on a daily basis. In addition, snapshots for the last 7 days are available on line for quick restores. Long term archiving of files to tape (one or two copies) can be purchased as needed. Tape libraries are housed at two separete locations to enable disaster/recovery scenarios.  These research storage allocations can be easily mounted to desktops or other computer systems to allow for easy access and sharing files.

CCV will also consider hosting file servers and disk arrays for research groups. Server administration is included. There will be a hosting fee as well as a backup fee. Researchers are encouraged to use our GPFS storage and take advantage of global resources.

The following guidelines apply:

 1 - All faculty members at Brown can request a free allocation of 256 GB  (Rdata). Request Rdata Account 

 2 - PI’s may share their Rdata allocations with students, staff and coworkers. Instructions to mount Rdata to your desktop 

 3 - Additional space can be purchased on a monthly basis or for long term storage for a period of 6 years. Longer terms can be requested. Backups are included

 4 - Data is incrementally backed up to tape on daily basis 

 5 - Standard data retention period is 30 days. Longer terms are considered on request 

  6 - Archiving data to tape (e.g., raw data) is available per request

 7 - After the end of the grant, data may be copied to tape or hard drives and placed under the PI’s care 

 8 - For fees and additional information please consult the CCV rates web site  rates. Authentication is required.

Research file storage at Brown

 

Rdata: All faculty members at Brown University have access to a free allocation of 256 GB, called Rdata.

  • Rdata is accessible from all CCV systems (/gpfs/data)
  • Can be mounted to all desktops on Brown's campus network
  • Is backed up on a daily incremental basis
  • Rdata allocations can be increased by purchasing additional storage

Home directory on Oscar: All users will have access to a home (/gpfs/home) allocation of 10 GB. This allocation is backed up on a daily basis.

Group storage: Premium accounts (see premium) will be entitled to an additional allocation of 256 Gb that may be merged with Rdata (for primary PI). Likewise, group premium accounts will be entitled to additional 25 GB per user.

Snapshots: Daily snapshots are available for both Rdata and Home file systems for 7 consecutive days.

/scratch: Space for temporary files is available as (/gpfs/scratch). These files are not backed up and is strictly for temporary files. Files may be purged after 30 days or as the file system is being utilized. This allocation will be managed by an application called xdisk (time versus space) (work in progress).

Dropbox: Sharing files that are too big to be sent via email. There is a 10 GB quota and a limit of 2 GB per file. (see dropbox.brown.edu)
