OSNEXUS QuantaStor vs ZetaNAS

OSNEXUS QuantaStor manages file, block and object storage in a software-defined platform. Built on Ceph and OpenZFS, it can scale up or out while managing storage across one grid. Administrators can configure it through a web interface designed for IT generalists, or manage and automate Storage Grid servers with CLI tools and REST APIs. QuantaStor is available as ISO installation media for bare metal or virtual machines, and as a VMware OVA appliance. Its Cloud Integration SDK supports automated provisioning, storage-cloud management and auditing through RESTful APIs. OSNEXUS describes data protection in transit and at rest. For Ceph users, listed security features include AES-256 encryption, S3 Object Lock, MFA and RBAC; the Ceph page also lists alerts through email, Slack and SNMP, plus hardware monitoring. The free Community Edition is limited to 80TB raw capacity and four servers per grid, for non-commercial, educational and testing use. The Trial Edition is free for 45 days, with 256TB raw capacity and Enterprise Edition features unlocked.

ZetaNAS is an open-source network-attached storage platform 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. Built-in deduplication, erasure coding, and intelligent compression are described as reducing physical storage use by 30% or more. Security and reliability features include EC replication, disk-health monitoring, fault isolation, access control, and auditing. Media tools provide multi-device sync, version history, previews, and chunked transfer. Shared workspaces add real-time synchronization and granular access control. Medical deployments support DICOM and WSI data, annotation, and quality control. AI workloads can stream through S3 and FUSE to GPU nodes. A Docker-based app store manages extensions.
