Open-E JovianDSS Integration with Proxmox VE:
Minimized Hardware Usage with Multiprotocol Platform

See how our team took hypervisor-agnosticism to the next level! Experience a new, stable, and reliable way of managing your Virtual Machines & their data!

Cut Up To 20% On System Costs with Data Storage Solution for Proxmox VE

Our Open-E JovianDSS Proxmox Plugin is a unique solution on the market, delivering a cost-effective, hardware-agnostic multiprotocol data storage solution for both iSCSI and NFS. Our unique High Availability configuration slashes hardware costs and prevents split-brain, protecting virtual machines and critical backup workloads, especially within your hyper-converged infrastructure.

By combining Open-E’s 25+ years of data storage expertise with cost-efficient but powerful Proxmox VE, businesses gain a cutting-edge, budget-friendly alternative to costly virtualization platforms without sacrificing protocol choice, data storage consolidation, or high availability. 

 

Optimized Lean HA 2+1 Cluster Architecture

You can run your production cluster on two high-performance nodes and use a third, budget-friendly node (using standard commodity hardware) for both quorum and dedicated backups. This lowers your total cost of ownership while keeping full high availability. It’s a key advantage over standard Proxmox VE setups, which require three identical, high-performance nodes to handle quorum and data redundancy.

  • Up to 20% Cost Reduction Per System
  • Data Protection with Proxmox Backup Server
  • No 3rd Node Open-E JovianDSS license is required!
  • User-Friendly Configuration & System Management

Open-E JovianDSS iSCSI Proxmox VE Plugin

Open-E JovianDSS iSCSI Proxmox VE Plugin delivers a high-performance block storage backend with full path redundancy and automated target handling. Check the Open-E JovianDSS iSCSI Data Sheet to learn more about:

  • Full iSCSI Auto-Multipathing: Aggregates multiple physical I/O paths into a single logical device to eliminate single points of network failure and balance traffic.
  • Automated Target Management: Dynamically provisions, attaches, and detaches dedicated iSCSI targets without manual intervention.
  • Granular VVOL-Like Architecture: Assigns dedicated Open-E JovianDSS volumes with a single iSCSI target per VM or container for isolated snapshot and rollback control.

 

Open-E JovianDSS NFS Proxmox VE Plugin

Designed for seamless file-based virtualization, the Open-E JovianDSS NFS Proxmox VE Plugin optimizes storage performance by integrating directly with ZFS datasets while bypassing conventional disk image bottlenecks. Check the Open-E JovianDSS NFS Data Sheet to learn more about:

  • QCOW2 Layer Removal: Bypasses intermediate QCOW2 image overhead to execute storage operations directly within ZFS for maximum speed.
  • Unified Shared Dataset: Stores VM images, container root directories, and ISO files together within a single central NFS-exported ZFS dataset.
  • Native ZFS Operations: Executes instant snapshots, clones, and rollbacks directly at the ZFS layer to accelerate disaster recovery routines.

Frequently Asked Questions - Open‑E JovianDSS Plugin for Proxmox VE

Currently, you cannot send ZFS snapshots directly to Proxmox Backup Server (PBS). However, developers and the community are actively working on a plugin solution to integrate ZFS snapshot transfers with PBS in the future.

It is a single plugin that contains both iSCSI and NFS functionality built into it. It was initially advertised for iSCSI while NFS was undergoing QA testing, but both capabilities were included in the same plugin from the beginning and are now fully supported.

Yes. A Open-E JovianDSS HA Metro Cluster running on separate bare-metal servers can provide iSCSI storage to multiple Proxmox hosts or even multiple Proxmox clusters. This is supported through the cluster-prefix property in the plugin configuration.

The performance difference is very minimal and comparable, depending on whether you measure random or sequential reads/writes. However, iSCSI is preferred for mission-critical setups because it supports true switch-agnostic multipathing, whereas NFS requires network bonding, which depends on specific switch capabilities and can encounter issues during network disruptions.

Yes. When using NFS, Open-E JovianDSS On- and Off-site Data Protection (OODP), the built-in backup and replication functionality, can be used as a backup and disaster recovery solution. With the NFS part of the plugin, multiple virtual disks are stored in a single ZFS dataset. A single OODP replication task can therefore back up all virtual disks stored in that dataset at the same time.

Yes. The Metro Cluster requires a dedicated Mirror Path. The recommended configuration is a switchless, direct point-to-point connection using either a single network interface or bonded interfaces. In our webinar demo, we configured one NIC as a PCI passthrough device. As a result, Open-E JovianDSS sees it as a physical NIC rather than a virtual interface. This passthrough NIC is used for the Mirror Path. The passthrough NICs in pve1 and pve2 are connected directly to each other using a point-to-point connection, without a network switch. A direct point-to-point connection is recommended for the Mirror Path, although a switched network connection is also supported.
