NovaNAS vs OSNEXUS QuantaStor

NovaNAS is a free, open-source NAS operating system managed through a desktop-like web interface. Its browser file manager supports browsing, uploading, downloading, and previewing files. Storage features include ZFS and EXT4, RAID management, and SMB/CIFS and NFS shared folders with access controls. A community app store offers one-click deployment of Docker applications such as Plex, Nextcloud, and Pi-hole. The project describes automated backups to external drives or cloud storage, and network backups between NovaNAS systems using API key authentication. Security and network tools include UFW firewall management, DynDNS, automatic Let's Encrypt certificates, and WebAuthn/FIDO2 passkey login. The interface monitors CPU, memory, disk, and network activity in real time. NovaNAS currently supports Debian 13 only, and its installer is intended for a fresh system, not an existing one. Minimum requirements are 2 GB RAM, a 1-core CPU, and a 20 GB system drive, plus data drives. Virtualization, historical monitoring, and scheduled tasks are listed as coming soon.

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.
