Open-E JovianDSS Proxmox

Overview

The Open-E JovianDSS Proxmox plugin enables Proxmox VE clusters to use Open-E JovianDSS storage pools as backend storage via iSCSI.

It provides:

• Automated Volume Management: Dynamically attach/detach iSCSI targets and manage multipath devices.
• High Availability: Support for Open-E JovianDSS failover and multipathing across multiple network interfaces.
• Thin Provisioning: On-demand volume allocation to optimize storage usage.
• Cluster-wide Integration: Treat storage as shared, enabling live migration and HA features in Proxmox VE.

Documentation

• Start using the plugin by going through the Quick Start guide.
