Ceph Monitors

Ceph Monitors (MONs) are central servers that keep track of the overall health and configuration of a Ceph storage cluster. They manage metadata, maintain a map of the storage nodes, and ensure data consistency and fault tolerance. Think of them as the "brain" of the cluster, coordinating activity and preventing conflicts. Typically, multiple monitors run together to provide high availability, so if one fails, others can seamlessly take over. This setup helps the Ceph system remain reliable, scalable, and resilient, ensuring data is stored securely and accessible at all times.
