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

(even dynamic) scaling capabilities.Ceph uses an interesting alternative instead of relying on the allocation list (which maps the blocks on the disk to the metadata of the specified file). A file in a Linux perspective is assigned to an inode number (INO) from the metadata server, which is a unique identifier for the file. The file is then pushed into some objects (depending on the size of the file). With INO and object number (ONO), each object is
