A fault-tolerant, network-distributed parallel storage system.
MooseFS is distributed storage software. It spreads your data across multiple servers while keeping it accessible as a single resource. Mount it as a POSIX file system, use it as a block device for VMs and databases, or access it directly via the C API — the choice is yours. Add commodity hardware to scale. Lose a server or disk and nothing breaks. In production since 2005, it fits virtually any stack — from legacy applications to high-performance workloads. Available as open-source or PRO edition.
MooseFS v5
Geo-aware storage · Enhanced I/O Security
Split your cluster across datacenters with per-location storage policies and smarter leader election.
New cluster-wide authentication ensures all data access is gated through the master — no bypassing export permissions at the storage layer.
