Rados:a scalable, Reliable Storage Service for Petabyte-scale Storage ClustersThesis translationSummaryBlock and object-oriented storage architectures form a storage cluster that promotes extensibility. However, existing systems continue to use storage nodes as a passive device, although they have the ability to demonstrate intelligence and autonomy. We propose rados design and implementation, Rados is a reliable object-oriented service that can be ex
