• RADOS Gateway (RGW): RGW provides an interface for object storage that is compatible with S3 and Swift APIs. It allows applications to interact with Ceph’s object storage using industry-standard protocols, making it easier to integrate with existing systems and applications.
• Managers (Ceph-MGR): The manager daemon collects and exposes various metrics about the cluster's performance and state. It provides additional services like the dashboard, monitoring, and management interfaces, and integrates with external monitoring systems.
• Clients: Clients interact with the Ceph cluster to read and write data. They use different interfaces, such as librados for low-level access, librbd for block device operations, and CephFS for file system interactions. These clients ensure seamless integration with applications and systems.

Data Distribution and Placement with CRUSH Algorithm

One of Ceph’s most powerful features is its intelligent data distribution and placement mechanism, managed by the CRUSH (Controlled Replication Under Scalable Hashing) algorithm. CRUSH is designed to efficiently distribute data across the cluster while ensuring high availability and fault tolerance.

• CRUSH Algorithm: CRUSH uses a pseudo-random algorithm to determine how and where data should be stored within the cluster. Instead of relying on a centralised lookup table, CRUSH calculates data placement dynamically, based on the cluster map maintained by the MONs. This ensures that data is evenly distributed across all OSDs, optimising performance and resilience.
• Data Replication: CRUSH ensures that data is replicated across multiple OSDs according to the predefined replication policy. This replication provides redundancy, ensuring that data remains accessible even if one or more OSDs fail.
• Erasure Coding: In addition to replication, Ceph supports erasure coding, which provides a more storage-efficient method of achieving fault tolerance. Erasure coding breaks data into fragments and stores them across the cluster, allowing data to be reconstructed even if some fragments are lost.
• Customisable Policies: Administrators can define custom CRUSH maps and rules to tailor data placement to specific requirements. For example, data can be placed in specific racks, rows, or data centres to meet regulatory compliance or performance needs.
• Load Balancing: CRUSH continuously monitors the distribution of data and automatically rebalances it as needed. This dynamic rebalancing ensures optimal use of available resources and consistent performance.
• Ceph’s Self-Healing and Fault Tolerance Mechanisms

Ceph’s architecture includes robust self-healing and fault tolerance mechanisms to ensure data integrity and availability:

• Automatic Recovery: When an OSD fails, Ceph automatically detects the failure and triggers a recovery process. Data stored on the failed OSD is replicated to other OSDs to maintain the desired replication level. This process is transparent to users and helps maintain data availability.
• Backfilling: During recovery, Ceph performs backfilling to redistribute data and restore balance across the cluster. Backfilling ensures that new and existing data is evenly distributed, preventing overloading of any single OSD.
• Scrubbing: Ceph periodically performs scrubbing operations to check for inconsistencies in stored data. Scrubbing compares data and metadata across OSDs, identifying and correcting any discrepancies. This proactive approach helps maintain data integrity.
• Data Integrity Checks: Ceph includes built-in mechanisms for data integrity verification. Checksums are used to detect data corruption, and automatic repair processes are initiated when corruption is detected. This ensures that stored data remains accurate and reliable.
• Cluster Monitoring: Ceph continuously monitors the health and status of all cluster components. The MONs and Ceph-MGRs provide real-time insights and alerts, enabling administrators to quickly identify and address potential issues before they impact the system.
• Fault Domains: Ceph allows administrators to define fault domains, such as racks or data centres, to optimise data placement and enhance fault tolerance. By ensuring that replicas are stored in different fault domains, Ceph minimises the risk of data loss due to localised failures.

Ceph’s technical architecture, combined with its intelligent data distribution and robust fault tolerance mechanisms, makes it a powerful and reliable storage solution for modern enterprises. Next, we will explore the benefits of using Ceph for high-performance computing (HPC) and big data analytics, highlighting its suitability for demanding workloads.
