ZetaNAS
What it is
ZetaNAS is an open-source network-attached storage system for SMBs, startups, and teams running AI or machine-learning workloads. It combines file sharing, collaboration, and data pipelines, with native S3 and POSIX access plus NFS/PNFS support. The system runs on mainstream x86 or ARM hardware and can expand from one server to distributed clusters. The maker lists deduplication, erasure coding, and intelligent compression as reducing physical storage consumption by 30% or more. Reliability and security functions include EC replication, disk-health monitoring, fault isolation, access control, and auditing. Media workflows provide multi-device synchronization, version history, online preview, and chunked transfer for large files. Shared business documents support real-time sync, complete history, and granular permissions. Medical research deployments can use DICOM and WSI storage, annotations, and quality control. AI data pipelines stream through S3 and FUSE interfaces with low-latency paths to GPU nodes. A Docker-based ZetaAPP Store manages extensions. Plans include a free self-hosted community edition, Cloud at $99 a month, and Enterprise at $499 a month.
