LizardFS vs MinIO AIStor

LizardFS is an on-premises distributed file system that combines storage from several servers into a single namespace. Data is kept in multiple replicas across available servers, and new servers can be added without downtime; chunks move automatically to balance disk use. Erasure coding divides data into parts and parity stripes, with the maker stating that it can save up to 70% of storage capacity depending on configuration. Snapshots copy metadata while sharing data chunks until a file changes. Georeplication can copy data between data centers and lets administrators choose where data is stored. Administrators can set read and write bandwidth limits and apply soft or hard quotas for file counts and total size. Deleted files go to an administrator-visible trash bin for restoration or permanent deletion. Storage is installed on Linux, with Windows and macOS clients for cluster access. LizardFS supports NFS 3.x, NFS 4.0, and pNFS, and the maker describes using it with Elasticsearch and Logstash. Pricing is available on request; support packages include weekday or 24/7 assistance depending on tier.

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.
