Ceph vs MinIO AIStor

Ceph is free, open-source distributed storage software for object, block, and file storage in one system. Organizations run clusters on commodity hardware that they choose and manage. Its RGW object storage supports the S3 API and Swift-compatible applications. RBD provides thin-provisioned disk images, snapshots, writable clones, and asynchronous mirroring to remote Ceph clusters. CephFS is a POSIX-compliant distributed filesystem with snapshots, quotas, and multi-cluster mirroring. The system can replicate data across devices, racks, and geographic locations, then redistribute it following hardware or connectivity failures. For Kubernetes, the project recommends Rook to run Ceph or connect an existing cluster; its CSI driver can provision block and file volumes. Installation choices include packages, container images, source clones, and tarballs. The cephadm tool requires Python 3, systemd, and Podman or Docker. Production guidance calls for at least three monitors, two managers, three OSDs, and 10 Gb/s networking between hosts. The project publishes a stable release annually and supports each series for approximately 24 months.

MinIO AIStor combines persistent memory, tables, objects, and files in an enterprise AI data store. AIStor Memory holds agent context, workspaces, secrets, artifacts, and telemetry. AIStor Tables provides native Apache Iceberg storage for analytics, feature stores, lakehouse architectures, and structured AI datasets. S3-compatible object storage covers models, checkpoints, training datasets, embeddings, documents, media, and logs. Access and integration options include S3, S3 Express, MCP, SFTP and Files, Iceberg Catalog, and OpenSharing. Management features include an admin console, QoS, lifecycle management, encryption, key management, a data firewall, and immutability. The product lists several replication modes, along with audit trails, Prometheus metrics, and error logs. Installation options include Linux, Windows, macOS, Kubernetes Helm, OpenShift, and Podman. AIStor Free costs nothing and includes the full feature set, but is intended for single-node, self-supported use without resilience beyond one node; redistribution is prohibited. Enterprise and Enterprise Lite pricing is available on request. Lite is for capacity requirements below 400 TiB; deployments exceeding that are upgraded to Enterprise. A 60-day trial is listed.
