CSL: Policies: Project Disk Space
As an alternative to buying external disks for research data, the CS Lab now offers moderate amounts of disk space on the departments Network Appliance FAS 3020 filer. Project space on the filer offers several advantages to purchasing external disks, the sole option available to researchers in the past. The filer offers a robust RAID 4 disk array, coupled with a gigabit ethernet link, for fast file access throughout the department. In addition, the filer give the researcher access to snapshots, which allow accidentally deleted or altered files to be recovered from disk, by the user, in addition to the department's tape backups. Also with the filer, a researcher can increase the amount at any time by sending a request to the lab staff. Finally, the researcher can maintain the space as long as needed without having to worry about the replacing failed disk hardware.
- Each primary faculty member automatically recieves a 50 GB project
partition on the NetApp Filer; additional space is avaliable
upon request. The project spaces is named according to the
following convention:
/usr/project/{username}/ - Individual projects, whenever possible, should go under the PI
faculty project space. If desired, an automount of the project
subdirectory can be created to make the project appear to not be
a faculty sub-directory. For example:
faculty directory: /usr/project/schmidt/ project subdirectory: /usr/project/schmidt/widget/ subdirectory automount: /usr/project/widget/
This arrangement provides a self-documenting association between the project directory and the PI, yet is functionally equivalent to being a top-level project directory. - Exceptions can be made for multi-PI projects - these can be created outside of any particular faculty's project space.
- This space is on monthly full and daily incremental backups. Please do not use it for temp space or junk that does not neet to be regularly backed up, unless special arrangements are made.
We've gone ahead and created your project space. Please take a look, and be sure to adjust permissions and group access to your needs. If you do not want or need the additional space, please let us know and we'll delete it; it can always be recreated later.
If you have any questions, please contact the Lab Staff.
