In their own words
Open-E JovianDSS
Open-E JovianDSS is Linux- and ZFS-based software-defined storage for NAS, SAN, backup, business continuity, and disaster recovery. It supports iSCSI, Fibre Channel, NFS, SMB (CIFS), and NVMe-oF, and can run on physical servers or as a virtual storage appliance in hyper-converged environments. Listed virtualization compatibility includes VMware, Proxmox, Citrix, and Microsoft Hyper-V. Its storage features include pools, unlimited scalability, unlimited file and volume size, and unlimited snapshots and clones. It supports shared-storage and non-shared-storage high-availability clusters, plus snapshot-based backup and replication for on-site and off-site protection. JovianDSS Up33 supports native ZFS encryption at dataset or volume level. Licensing depends on architecture and capacity: mirrored arrays use usable capacity, while parity arrays count disk capacity excluding cache and spares. Prices include a 670.00 USD one-time 0TB product license and a 670.00 USD one-time 4TB extension. A 60-day trial is offered; there is no free plan.
PetaSAN
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.
