The ceph-client repository is the kernel module implementation of the Ceph distributed storage client for Linux. Written primarily in C, this repository contains the kernel-space components that enable Linux systems to interact with Ceph storage clusters at the operating system level. The repository is classified across multiple storage and distributed systems domains including distributed storage, object storage, block storage, file systems, and cloud infrastructure, reflecting its role as a critical bridge between the Linux kernel and Ceph's distributed storage architecture.
The Ceph kernel client provides the low-level kernel drivers and modules necessary for Linux systems to mount and access Ceph storage resources directly from the kernel, rather than relying solely on user-space libraries. This approach offers performance advantages for applications requiring direct access to Ceph's RADOS object storage backend, as well as support for Ceph's block storage (RBD) and file system (CephFS) interfaces. By operating at the kernel level, the client can integrate tightly with Linux's I/O subsystems and provide transparent access to distributed storage resources.
The repository's primary language is C, which is standard for kernel modules and ensures compatibility with the Linux kernel's module interface and coding conventions. The project maintains a connection to the broader Ceph ecosystem through its homepage at http://ceph.com/, positioning it as an official component of the Ceph distributed storage platform. The classifications assigned to this repository emphasize its role in enabling scalable, fault-tolerant, and highly available storage infrastructure suitable for data center and cloud computing environments.
According to GitGenius activity tracking, the repository has demonstrated modest but consistent community interest. Between the previous check on July 5, 2026, and the current assessment, the repository gained one additional stargazer, growing from 214 to 215 stars. While this represents incremental growth, it reflects ongoing engagement from developers and organizations utilizing or contributing to the Ceph kernel client.
The repository's documentation and structure are designed to support kernel developers, system administrators, and storage infrastructure engineers who need to understand, deploy, or contribute to the Ceph kernel client. The project serves as a critical component for organizations implementing Ceph-based storage solutions in production environments, particularly those requiring kernel-level integration for performance-sensitive workloads. The ceph-client repository thus occupies an important position in the distributed storage ecosystem, providing the essential kernel-space functionality that allows Linux systems to participate fully in Ceph clusters.
