> **Note**

Data and storage / object storage

Component Description [#component-description]

`MinIO` was an S3-compatible object storage platform used to store artifacts, files, and binary assets in earlier versions of the platform. It has been replaced by `Rook-Ceph`, which provides the same S3 interface through its RADOS Gateway (RGW) along with `CephFS` for shared file storage.

Why It Was Used [#why-it-was-used]

In previous versions of BullSequana AI, MinIO provided object storage for platform artifacts and operational data. It was replaced because the upstream MinIO open-source distribution was deprecated. Platform components that previously consumed MinIO (`MLflow`, `Argo Workflows`, `Tempo`, `KubeAI`, `Milvus`) now connect to the `Rook Ceph` RGW endpoint.
