Data Redundancy: Ceph uses data replication and erasure coding techniques to ensure data redundancy and fault tolerance. This means that even if some nodes or devices fail, data remains.
In this enlightening video, we explore the world of Ceph redundancy and the essential requirements for seamless data read and write operations within a clust.At least 3 Ceph OSDs are normally required for redundancy and high availability.

On-disk journals can halve write throughput to the cluster. Ideally, you should run operating systems, OSD data and OSD journals on separate drives to maximize overall throughput.
Via its advanced CRUSH algorithm, automated data redundancy, self-management daemons and much more, Ceph ensures data is safely stored, instantly available and optimally distributed for effective disaster recovery.CRC Checks: In Red Hat Ceph Storage 4 when using BlueStore, Ceph can ensure data integrity by conducting a cyclical redundancy check (CRC) on write operations; then, store the CRC value in the block database. On read operations, Ceph can retrieve the CRC value from the block database and compare it with the generated CRC of the retrieved data .
