DPlaneOS vs PetaSAN

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.

PetaSAN is an open-source, software-defined storage platform for Linux and self-hosted web-managed deployments, licensed under AGPL 3. It uses Ceph and Consul, delivering storage through iSCSI, CIFS/SMB, NFS, and S3. Capacity can grow by adding nodes without interrupting service, and the system is described as multi-node active/active and highly available. Graphical interfaces are intended to help non-Linux administrators install and operate it. Listed use cases include VMware vSphere, Hyper-V, scale-out file systems, big-data analytics, database servers, and large-capacity backups. Capabilities include storage pools, user management, and snapshots. The self-support plan costs nothing; professional support and engineering consultation are also offered. Version 4.1.0 is dated February 18, 2026, and release 3.3.0 added dm-crypt OSD encryption and an HTTPS deployment wizard.
