|Abstract:||For over a decade, dCache is synonymous with large-capacity, fault-tolerant storage using commodity hardware that supports seamless data migration to and from tape. It has satisfied the requirements of various demanding scientific user communities to store their data, transfer it between sites and to allow fast, site-local access.
However, with closer involvement in European Projects, like the European Middleware Initiatives (EMI), and consequently better relationship to industry and to HPC through the UNICORE project, the focus of dCache moved away from community specific solutions towards commonly accepted industry standards and mechanisms, enabling dCache to satisfy the needs of essentially any storage centric community. Most prominently, with the integration of http/WebDAV and parallel NFS (NFS4.1/pNFS) dCache is now the perfect Open Source storage solution for HPC.
However, technologies are changing and traditional data models are being revised. As a consequence, dCache is implementing a 3-Tier storage model, allowing benefits of Solid State Disk as well as traditional tape technologies to be taken advantage of. Moreover, storage cloud usage for dCache is in preparation in two ways: dCache using the emerging cloud space as tertiary storage pool and, on the other hand, allowing cloud applications to utilize dCache as their cloud storage provider.
This presentation is targeting to provide a brief overview of the benefits using our technology in HPC applications, as well as sketching a picture of the international dCache.org project itself.
