The Foundation for Large Scale
Data Infrastructure

MinIO will run anywhere and on any cloud but most often operates on commodity servers with locally attached drives (JBOD/JBOF). All of the servers in a cluster are equal in capability (fully symmetrical architecture). There are no name nodes or metadata servers.

MinIO writes data and metadata together as objects, eliminating the need for a metadata database. In addition MinIO performs all functions (erasure code, bitrot check, encryption) as inline, strictly consistent operations. The result is that MinIO is exceptionally resilient.

Each MinIO cluster is a collection of distributed MinIO servers with one process per node. MinIO runs in the user space as a single process and uses lightweight co-routines for high concurrency. Drives are grouped into erasure sets (see our erasure calculator here) and objects are placed on these sets using a deterministic hashing algorithm.

MinIO is designed for large scale, multi-data center cloud storage services. Each tenant runs their own MinIO cluster, fully isolated from other tenants giving them the ability to protect them from any disruption on upgrade, update, security incidents. Each tenant scales independently by federating clusters across geographies.
