DPlaneOS vs NexentaStor

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.

NexentaStor is software-defined storage for enterprise applications, combining file services over NFS and SMB with block services over Fibre Channel and iSCSI. It is presented for databases, enterprise NAS, private cloud, virtual workloads, backup, and archives, and can scale from terabytes to petabytes. It runs on bare-metal hardware or as a virtual storage appliance in private-cloud and hyper-converged environments. Its perpetual license includes inline data reduction, unlimited snapshots, long-distance replication, and NexentaFusion management. Administrators can also use a VMware vCenter plugin or a self-documenting REST API. Named integrations or certifications include VMware, Microsoft, OpenStack, Commvault, Veeam, and NetBackup. Nexenta describes SMB 3 encryption and Windows-style access control lists for file storage, and a checksummed, self-healing filesystem for backup. Enterprise Edition includes scheduled replication for recovery point objectives of 15 minutes or longer; continuous replication requires an extra license. Pricing is on request, with a 45-day trial available after registration.
