Storage for Advanced Scientific Use-Cases and Beyond
The dCache project provides open-source storage software deployed internationally to satisfy ever more demanding scientific storage requirements. Its multifaceted approach provides an integrated way of supporting different use-cases with the same storage, from high throughput data ingest, through wide access and easy integration with existing systems. In this paper, we describe some of the recent features that facilitate the use of storage to maximise the gain from stored data, including quality-of-service management, heterogeneous systems — both through integrated tertiary storage support and geographical locality — the parallel NFS (pNFS) extension, and innovative delegated authorisation schemes.
