Redhat ceph

1. Red Hat Ceph Storage Architecture Overview

2. Introduction to Ceph • Open-source, software-defined storage platform • Provides object, block, and file storage in a unified system • Highly scalable and fault-tolerant • Designed for cloud infrastructure and big data workloads

3. Ceph Architecture Components • Ceph Monitors (MON): Maintain cluster state and quorum • Ceph Managers (MGR): Provide cluster monitoring and management • Object Storage Daemons (OSD): Store and replicate data • Ceph Metadata Server (MDS): Handles metadata for CephFS • RADOS Gateway (RGW): Provides object storage with S3/Swift APIs

4. CRUSH Algorithm • Controlled Replication Under Scalable Hashing (CRUSH) • Determines data placement dynamically • Eliminates centralized lookup tables • Ensures scalability and balanced distribution

5. Ceph Storage Interfaces • RADOS: Core object store layer • RBD (RADOS Block Device): Provides block storage • CephFS: POSIX-compliant file system • RGW: Object storage compatible with Amazon S3 and OpenStack Swift

6. High Availability & Scalability • Self-healing and self-managing storage • Data replication and erasure coding • No single point of failure • Scales horizontally by adding more nodes

7. Use Cases of Red Hat Ceph Storage • Cloud infrastructure (OpenStack, Kubernetes) • Big data analytics • Backup and archival storage • High-performance computing (HPC) • Enterprise storage consolidation

8. Summary • Red Hat Ceph provides a unified, scalable storage solution • Combines object, block, and file storage • CRUSH algorithm ensures efficient data placement • Ideal for cloud, big data, and enterprise workloads
