Analyses of the usefulness of Software Defined Storage Solutions for Web-based Digital Preservation Applications

Presentation at Open Repositories 2014, Helsinki, Finland, June 9-13, 2014General Track Papers and PanelsThe session was recorded and is available for watching (this presentation starts at 0:25:55)The Digital Repository Of Ireland (DRI) is an interactive, national trusted digital repository for contemporary and historical, social and cultural data held by Irish institutions. The DRI has a requirement for a massively scalable, fully featured storage solution to store and preserve digital assets. Software defined storage has brought large scale storage within the reach of ordinary engineers and developers. The power and features provided by such systems can prove revolutionary and has the potential to deliver stable, vastly scalable storage to repository infrastructures at low cost. This presentation will explore four such solutions: Ceph, iRODS, GPFS and HDFS. Their features will be analysed and tested to assess suitability for the DRI. Criteria useful to digital repositories such as High Availability, Interfaces and Interoperability, replication and data security will be used to determine which solution best fits.Tiernan, Peter (TCD, Ireland)Tang, Jimmy (TCD, Ireland)Bako, Kristina (TCD, Ireland
