Yannick Legré, EGI: Managing director.
Title: Building Scale-Out Storage Infrastructures with RADOS and Ceph
Ceph and its core RADOS object store present a compelling building block for architecting very large storage clusters out of commodity hardware. However, several early design decisions can have lasting implications for a Ceph-based infrastructure. For example, which of Ceph's APIs should I build upon - RADOS, S3, block, POSIX? Should we build a single multi-tenant cluster, or are targetted smaller deployments somehow better? Erasure-coding looks inexpensive on paper, but are there performance implications? When and where does it pay off to add flash? This talk will attempt to answer these and other questions about Ceph, based on our 4 years' experience operating multi-petabyte Ceph clusers for OpenStack, scientific data, and HPC.

Title: Data, Software, and Knowledge Preservation of Scientific Results
Simply preserving the data from a scientific experiment is rarely sufficient to enable the re-use or re-analysis of the data. Instead, a more complete set of knowledge describing how the results were obtained, including analysis software and workflows, computation environments, and other documentation may be required. This talk explores the challenges in preserving the various knowledge products and how emerging technologies such as linux containers may provide solutions that simultaneously enable preservation and computational portability. In particular, the work of the Data and Software Preservation for Open Science (DASPOS) project and the building of the CERN Analysis Preservation Portal will be highlighted.
