DiGS — Distributed Grid Storage

DiGS is a distributed-data management system that combines commodity storage resources — such as RAID systems and Storage Area Networks — into a large-scale, unified file repository, which is presented to the end-user through an easy-to-use, lightweight client toolkit.

The DiGS application is built on top of the Globus Toolkit and the EGEE application stack.

The key features of DiGS are:

  • capacity for multi-Terabyte, distributed storage.
  • robustness with automatic and transparent replication of data across multiple sites.
  • continuous data validation and consistency checking.
  • support for bulk data transport operations.
  • security based on standards-compliant techniques for authentication and authorisation.
  • capability for data provenance with application-specific metadata.
  • simple and intuitive client tools.
