Dynamic federations: storage aggregation using open tools and protocols / Fabrizio Furano, F F (CERN ; fabrizio.furano@cern.ch) ; Patrick Fuhrmann, P F (DESY) ; Ricardo Brito da Rocha, R R (CERN ; ricardo.rocha@cern.ch) ; Adrien Devresse, A D (CERN ; adrien.devresse@cern.ch) ; Oliver Keeble, O K (CERN ; oliver.keeble@cern.ch) ; Alejandro Alvarez Ayllon, A A (CERN ; alejandro.alvarez.ayllon@cern.ch)
A number of storage elements now offer standard protocol interfaces like NFS 4.1/pNFS and WebDAV, for access to their data repositories, in line with the standardization effort of the European Middleware Initiative (EMI). Also the LCG FileCatalogue (LFC) can offer such features. [...]

Dynamic federation of grid and cloud storage / Furano, Fabrizio (CERN) ; Keeble, Oliver (CERN) ; Field, Laurence (CERN)
The Dynamic Federations project (“Dynafed”) enables the deployment of scalable, distributed storage systems composed of independent storage endpoints. While the Uniform Generic Redirector at the heart of the project is protocol-agnostic, we have focused our effort on HTTP-based protocols, including S3 and WebDAV. [...]

Towards an HTTP Ecosystem for HEP Data Access / Furano, Fabrizio (CERN) ; Devresse, Adrien (CERN) ; Keeble, Oliver (CERN) ; Hellmich, Martin (CERN) ; Alvarez Ayllon, Alejandro (CERN)
In this contribution we present a vision for the use of the HTTP protocol for data access and data management in the context of HEP. The evolution of the DPM/LFC software stacks towards a modern framework that can be plugged into Apache servers triggered various initiatives that successfully demonstrated the use of HTTP-based protocols for data access, federation and transfer.

Dynamic Federations: scalable, high performance Grid/Cloud storage federations / FURANO, Fabrizio (speaker) (CERN)
The Dynamic Federation project aims to give tools and methods to on-the-fly federate different storage repositories whose content satisfies some basic requirements of homogeneity. The Dynafeds have been designed to work in WANs, have given so far excellent results also in LAN, and are well adapted to working with the HTTP/WebDAV protocols and derivatives, thus including a broad range of Cloud storage technologies. In this talk we will introduce the system and its recent larger deployments, and discuss the improvements and configurations that can make it work seamlessly with Cloud storage providers. Among the deployment possibilities we cite: - seamlessly using different cloud storage providers at once, thus creating a federation of personal cloud storage providers - boosting client data access performance by optimizing redirections to data that is globally replicated - easy, catalogue-free insertion/deletion of transient endpoints - seamlessly mixing cloud storage with WebDAV-enabled Grid storage - giving a WAN-distributed WebDAV access backend to services like OwnCloud/CERNBox, to enable collaboration across administrative domains/sites..

Web enabled data management with DPM & LFC / Alvarez Ayllon, A (CERN) ; Beche, A (CERN) ; Fabrizio, F (CERN) ; Hellmich, M (CERN) ; Keeble, O (CERN) ; Brito da Rocha, R (CERN)
The Disk Pool Manager (DPM) and LCG File Catalog (LFC) are two grid data management components currently used in production with more than 240 endpoints. Together with a set of grid client tools they give the users a unified view of their data, hiding most details concerning data location and access. [...]

dCache, agile adoption of storage technology / Millar, Paul (speaker) (Deutsches Elektronen-Synchrotron (DE))
For over a decade, dCache has been synonymous with large-capacity, fault-tolerant storage using commodity hardware that supports seamless data migration to and from tape. Over that time, it has satisfied the requirements of various demanding scientific user communities to store their data, transfer it between sites and fast, site-local access. When the dCache project started, the focus was on managing a relatively small disk cache in front of large tape archives. [...]

Making the most of cloud storage - a toolkit for exploitation by WLCG experiments / Ayllon, Alejandro Alvarez (CERN) ; Arsuaga Rios, Maria (CERN) ; Bitzes, Georgios (CERN) ; Furano, Fabrizio (CERN) ; Keeble, Oliver (CERN) ; Manzi, Andrea (CERN)
Understanding how cloud storage can be effectively used, either standalone or in support of its associated compute, is now an important consideration for WLCG. We report on a suite of extensions to familiar tools targeted at enabling the integration of cloud object stores into traditional grid infrastructures and workflows. [...]
