CephFS Architecture and Administration

"CephFS Architecture and Administration"
"CephFS Architecture and Administration" is an authoritative guide that explores CephFS, the distributed file system built on the robust foundation of the Ceph storage platform. Beginning with the origins and design philosophy of Ceph, the book provides a comprehensive understanding of CephFS's place within the broader ecosystem, comparing its capabilities and performance traits to alternative distributed file systems such as Lustre and HDFS. Readers gain a firm grasp of CephFS's POSIX-compliant approach, object storage design, and the innovative architecture that powers modern cloud, high-performance computing, and data-intensive environments.
The book delves deeply into the internal workings of CephFS, dissecting its logical architecture, metadata server (MDS) subsystems, object storage daemons (OSDs), and critical components like the cluster monitor (MON) and CRUSH map. With practical guidance on planning, deploying, and managing CephFS clusters, it addresses real-world challenges including resource sizing, multi-tenancy, security configuration, and network design. Each operational chapter is supported by step-by-step instructions for deployment, integration, and best practices for scalability, robustness, and high availability, making it invaluable for both planners and administrators.
Advanced chapters address performance tuning, disaster recovery, security and compliance, and day-to-day operational management. With coverage of client integration, resource lifecycle management, quota enforcement, snapshots, and regulatory concerns, this book ensures readers can build, maintain, and scale secure CephFS deployments. Designed for systems architects, storage administrators, and DevOps professionals, "CephFS Architecture and Administration" is an indispensable resource for mastering every aspect of CephFS in production environments.
