Rados

Rados is a term that can refer to several different things. In onomastics, Rados is used as a Slavic given name and surname, often as a short form of Radovan or Radomir. It derives from a Slavic root associated with joy, care, or work, and it appears in various transliterations across countries such as Croatia, Serbia, and Slovenia. As a place name, Rados is also the name of several small villages or settlements in Slavic-speaking regions, where it functions as a geographic toponym rather than a personal name.

In computing, RADOS stands for Reliable Autonomic Distributed Object Store. It is the core storage substrate of the Ceph distributed storage platform. RADOS provides a scalable, distributed object storage service and is responsible for data placement, replication, recovery, and fault management across storage nodes. The system employs the CRUSH algorithm to determine how data is distributed across the cluster, enabling resilience and efficiency as the cluster grows. RADOS supports features such as replication and erasure coding to maintain data durability and availability in large-scale deployments, ranging from terabytes to petabytes of data.

Overall, the term Rados encompasses linguistic, geographic, and technical meanings, each rooted in distinct domains but occasionally intersecting in Slavic-speaking regions where names and places share cultural origins.
