RADOS: A Scalable, Reliable Storage Service for Petabyte-scale Storage Clusters

Brick and object-based storage architectures have emerged
as a means of improving the scalability of storage clusters.
However, existing systems continue to treat storage nodes
as passive devices, despite their ability to exhibit significant
intelligence and autonomy. We present the design and implementation
of RADOS, a reliable object storage service
that can scales to many thousands of devices by leveraging
the intelligence present in individual storage nodes. RADOS
preserves consistent data access and strong safety semantics
while allowing nodes to act semi-autonomously to selfmanage
replication, failure detection, and failure recovery
through the use of a small cluster map. Our implementation
offers excellent performance, reliability, and scalability
while providing clients with the illusion of a single logical
object store.
