【 摘 要 】

EOS is an open source distributed filesystem developed and used mainly at CERN. It provides low latency, high availability, strong authentication, multiple replication schemas as well as multiple access protocols and features. Deployment and operations remain simple and EOS is currently being used by multiple experiments at CERN providing a total raw storage space of 86PB. A brief overview of EOS's architecture is given then its main and latest features are reviewed and some operations facts are reported. Finally, emphasis is laid on the new infrastructure aware file placement and access engine.
