| Data protection | Objects can use erasure coding, replication, or no data protection; DAOS can trigger self-healing rebuilds when an engine becomes unresponsive. | Enterprise automatically repairs missing or corrupted erasure-coding shards and periodically checks shards against checksums for silent corruption. |
| Integrations | The DAOS client ecosystem includes libdfs for POSIX namespaces, and its user guide documents a PyTorch interface for loading data from DAOS. | The built-in Iceberg catalog supports querying with Spark, Trino, Dremio, and DuckDB. |
| Support | The DAOS site lists member support by email at [email protected] and links to a Linux Foundation support page. | Enterprise support is optional and purchased separately from the capacity license; published support channels and response targets vary by plan. |

In their own words
SeaweedFS
SeaweedFS is a distributed storage system that serves S3 objects, Iceberg tables, and POSIX files from one cluster. It supports S3, POSIX mounts, HDFS-compatible access, an Iceberg REST catalog, and WebDAV. Its built-in Iceberg catalog supports queries with Spark, Trino, Dremio, and DuckDB. The product describes scaling from gigabytes to petabytes and supporting billions of files. Development and testing under 25 TB are free, but production deployments require a paid license regardless of size. Monthly capacity licensing is $2 a month, based on used storage including replication or erasure-coding overhead; yearly licensing is $20 a year. Enterprise features include deleted-file recovery within a configurable retention window, point-in-time restoration, repair of missing or corrupted erasure-coding shards, and OIDC sign-in with role mapping. The free 25 TB trial limits deleted-file recovery retention to one hour. Enterprise support is optional and priced separately from capacity licensing. Community support is free and has no guaranteed response time. SeaweedFS is available for Linux, macOS, and Windows, with API access and self-hosted deployment.
