Summary

MinIO AIStor is an enterprise AI data store combining persistent memory, tables, objects, and files. AIStor Memory stores agent context, workspaces, secrets, artifacts, and telemetry, while 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 tools include encryption, key management, lifecycle controls, immutability, replication, audit trails, metrics, and error logs. Deployment options include Linux, Windows, macOS, Kubernetes Helm, OpenShift, and Podman. AIStor Free is free for single-node deployments with the full feature set, but is intended for self-supported use cases that need no data resiliency beyond one node; redistribution is prohibited. Enterprise and Enterprise Lite pricing is on request, and Lite is for capacity below 400 TiB.
