DPlaneOS vs OSNEXUS QuantaStor

DPlaneOS is a ZFS-first storage operating system for homelab and small-office NAS deployments. It manages pools, datasets, snapshots, replication, encryption, quotas, S.M.A.R.T. and POSIX ACLs, with sharing through SMB, NFS, iSCSI and NVMe-oF. It can manage Docker and Compose stacks, ZFS-clone sandboxes, atomic updates with rollback, and an in-browser terminal. Its architecture combines a Go daemon, PostgreSQL state, a React interface and a NixOS appliance. Identity options include local users, LDAP or Active Directory, OIDC SSO, TOTP 2FA and API tokens. Cloud synchronization supports S3, Backblaze B2, Google Drive, Azure, Dropbox and rclone-compatible targets. Prometheus/OpenMetrics exposes storage and system metrics. Optional high availability is off by default; several HA configurations and NVMe-oF over TCP are marked experimental. Installation supports x86_64 and aarch64, including Raspberry Pi 5, with offline ISOs. The free Community Edition is licensed under AGPLv3. Minimum hardware is a 64-bit CPU and 8 GB RAM; 16 GB is recommended. One person maintains the project, which offers no vendor support.

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.
