What ZetaNAS is
ZetaNAS is an open-source network-attached storage system for SMBs, startups, and teams using AI or machine-learning workloads. It combines file sharing, team collaboration, and data pipelines, with 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. Its maker says deduplication, erasure coding, and intelligent compression reduce physical storage consumption by 30% or more. Listed security and reliability features include EC replication, disk health monitoring, fault isolation, access control, and auditing. Media collaboration includes multi-device sync, version history, online preview, and chunked transfers for large files. Shared business documents support real-time sync, history, and granular access control. Medical research workflows include private deployment, DICOM and WSI storage, annotation, and quality control. For AI data workloads, ZetaNAS streams through S3 and FUSE interfaces, with low-latency paths to GPU nodes and private pipelines. A Docker-based ZetaAPP Store manages extensions. The free self-hosted plan supports x86 and ARM hardware, with no capacity or node limits and two official extensions. Cloud costs $99 a month; Enterprise costs $499 a month.
