Description
The EOS system is an advanced distributed storage system that deals with many extreme uses-cases (massive data injection from the LHC, latency-critical online home directories and massive throughput accesses from batch farms).
EOS implements many site reliability engineering best practices to support these uses cases at scale and also to support the work done by the operations team maintaining the production clusters.
In this presentation we explain some of the functionalities implemented in the core of EOS (logging, retry mechanism, QoS) that allows a smooth operation of the service while accommodating the diverse use-cases cited above.
