Network (Scratch) Storage

Introduction

GDSC provide networked storage as a relatively cheap solution for storing raw data on a temporary basis. This should be thought of as a short term location only.

  • This storage isn't currently backed up, but is still orders of magnitude better than portable drives.
  • On request, ITS will create directories at the top level and can apply AD group restrictions if needed (based on research group, users of a particular microscope, facs machine, individual researcher, facility, etc.).
  • However, the contents of these directories will not be managed by ITS; users must manage them themselves and be aware that other users within that group can delete files for example, either maliciously or by accident.
  • ITS will move data to tape on request, but this data must be easily identifiable (in a directory called 'archive' for example). Doing this will free up space. The archive is good for the life of the tape. Once the data is copied to tape a text file can be created listing the files, acting as a searchable record. The data will then be deleted.
  • Quota limits can be applied to directories but this isn't done at the moment.
  • ITS can bulk import data for you eg. from portable drives.

Research Group Directories

Notwithstanding the limitations described above we will endeavour to provide a directory for each research group with the following properties:

  • Group members only have access to their respective PI group directory
  • Only group members can create directories and files within the directory
  • The contents of any sub-directory are restricted to the directory owner (full rights), group administrator(s), which is usually just the PI, (ro rights) and microscopy administrators (full rights)

Access the Scratch Space

From a Windows PC

Map to: \\scratch.gdsc.sussex.ac.uk\scratch

From a Mac

Connect to server using: smb://scratch.gdsc/sussex.ac.uk/scratch

From a Linux workstation

ssh to: <username>@scratch.gdsc.sussex.ac.uk:/srv/scratch

From a remote location

User either remote-desktop or, using a terminal, ssh to unix.sussex.ac.uk. Once you've authenticated to the ITS systems within the firewall you can then access the scratch space (see above).
