Which open-source storage platform provides integrated block, file, and object storage for distributed environments?

• A. GlusterFS
• B. OpenEBS
• C. Ceph
• D. Lustre

Answer: (C)

This question tests a storage platform that provides unified access to block, file, and object storage across a distributed cluster. Ceph delivers this by design: its core RADOS distributed object store underpins all formats, while additional interfaces cover the different storage needs. Block storage is exposed through RADOS Block Device (RBD), ideal for VM and container workloads. File storage comes from CephFS, a scalable POSIX-compatible filesystem. Object storage is provided by the RADOS Gateway (RGW), offering S3 and Swift-compatible interfaces. Together, these capabilities let a single Ceph cluster serve multiple storage workloads in distributed environments. GlusterFS is primarily a distributed file system, not a built-in block and object storage suite. OpenEBS focuses on Kubernetes-native block storage rather than file or object storage, and Lustre is a high-performance parallel file system for HPC environments, not a unified block/file/object platform.
