Installation

The Ceph Object Store is the foundation of all Ceph clusters, and it consists primarily of two types of daemons: Object Storage Daemons (OSDs) and monitors. The Ceph Object Store is based upon the concept of RADOS, which eliminates single points of failure and delivers infinite scalability. For details on the architecture of Ceph and RADOS, refer to Ceph Architecture. All Ceph deployments have OSDs and monitors, so you should prepare your Ceph cluster by focusing first on the object storage cluster.

Recommendations To begin using Ceph in production, you should review our hardware recommendations and operating system recommendations. Many of the frequently-asked questions in our mailing list involve hardware-related questions and how to install Ceph on various distributions.
