Managing multi-site infrastructure just got a whole lot easier. Here is our comprehensive review of the first stable release of Proxmox Datacenter Manager.
If you have been in the system administration game for long enough, you know the "tab fatigue" struggle. You have a Proxmox Virtual Environment cluster in your primary data center, a standalone node at a disaster recovery site, and perhaps a few Proxmox Backup Servers scattered across different locations.
To manage them, you juggle VPNs, SSH tunnels, and a browser window so full of tabs you can’t read the titles anymore. For years, the community asked for a solution. Some tried to stretch standard PVE clusters across WANs – a recipe for disaster due to Corosync latency requirements. Others built custom scripts. But last week, Proxmox Server Solutions officially answered the call. Proxmox Datacenter Manager Version 1.0 is here. It is stable, it is production-ready, and it fundamentally changes how we orchestrate distributed infrastructure.
In this deep dive, we are exploring what PDM is, why it’s technically superior to "stretching" clusters, and why running it on a VPS might be your smartest move.
The official launch details
Proxmox Datacenter Manager officially reached its first stable milestone with the release of version 1.0 on December 4, 2025. This marks the platform’s transition from its earlier alpha and beta phases into a fully supported production-ready solution. The software is published as open source under the AGPLv3 license, ensuring transparency, community collaboration, and full access to the source code.
The "Federation" concept: How Proxmox Datacenter Manager solves the latency problem
Before we look at the features, it is vital to understand the architecture. This is the part that will save you from major headaches down the road.
A standard Proxmox VE Cluster requires all nodes to be in constant, sub-millisecond synchronization. If the network jitters, the cluster creates a "split-brain" scenario, potentially rebooting nodes. This is why you never cluster servers between London and New York.
Proxmox Datacenter Manager takes a fundamentally different approach. It is built for federation, not for traditional clustering. All communication happens over the API, which means it can tolerate significantly higher latency and occasional packet loss. Even if the connection drops completely, your PVE nodes continue operating normally – only the central dashboard becomes temporarily unavailable. This “loosely coupled” architecture makes PDM an ideal fit for:
- Hybrid Cloud: Managing on-prem hardware and rented dedicated servers.
- Edge Computing: Retail locations or branch offices.
- MSPs: Managing distinct client infrastructures securely.
Feature deep dive: What’s inside PDM 1.0?
The transition to Version 1.0 introduces a mature, production-ready feature set. After a year of public testing and rapid development, PDM now delivers the stability, consistency, and tooling expected from a fully supported release.
The Single Pane of Glass
PDM’s centralized dashboard is designed to eliminate the fragmentation that typically comes with managing distributed Proxmox environments. Instead of switching between individual nodes, clusters, or backup servers, the interface presents a unified, real-time picture of your entire estate – whether it spans a single rack or dozens of global sites.
- State: Instantly assess the health of every node. The dashboard highlights online/offline status, communication issues, and unreachable locations, allowing administrators to spot problems before they escalate.
- Resources: All compute and storage metrics are aggregated across sites, giving you a full understanding of overall capacity, utilization trends, and potential bottlenecks. This makes planning and scaling significantly easier.
- Resource lifecycle management: PDM centralizes fundamental management actions for Virtual Machines and Containers across multiple independent Proxmox clusters. This includes core tasks like starting, stopping, and migrating resources, as well as providing a direct link to the Proxmox VE admin interface for full control over the specific VM or Container.
-
Updates: PDM surfaces all pending Proxmox VE and PBS package updates in one view. Instead of logging into each machine individually, you can immediately see which nodes require patching and prioritize maintenance accordingly.
-
Management: For those times a node or cluster demands deeper customization, a single click provides immediate access to the required remote's GUI.
This consolidated management layer not only saves time but also reduces operational complexity, making multi-site Proxmox environments far easier to operate at scale.

Centralized Authentication & Access
PDM replaces scattered local accounts with a unified identity layer, supporting OIDC, LDAP, and Active Directory. Administrators define permissions once via a centralized ACL system that applies across all connected nodes.
Crucially, PDM securely proxies Shell and VM console sessions via HTTPS tunneling. This eliminates the need to expose SSH or management ports on remote nodes to the public internet. All access is authenticated and tunneled through PDM, allowing for strict firewall rules, centralized auditing, and a significantly reduced attack surface.
Comprehensive Backup Management
Proxmox Datacenter Manager treats Proxmox Backup Server as a core component and provides a unified overview of all connected backup servers. From a single interface, administrators can review backup clients, datastores, system resource usage, and storage contents – without logging into each PBS instance separately. For those times when direct access is required, PDM also offers convenient buttons to jump straight into the remote instance's GUI or console. PDM shows:
- All PBS instances and their datastores across every site.
- Job results and operational logs, making it easy to confirm backup success.
- Storage contents, helping ensure full coverage across distributed environments.
PDM doesn’t replace PBS configuration tools, but it serves as a centralized monitoring layer that keeps backup health visible across the entire Proxmox estate.

Cross-Cluster Live Migration with PDM: The boundary is gone
Until now, the powerful capability of Live Migration was strictly confined within the boundaries of a single Proxmox VE cluster. Proxmox Datacenter Manager 1.0 eliminates this limitation entirely, introducing a pivotal feature that unifies the operations of disparate and independent Proxmox environments.
Administrators can now execute Live Migration between independent clusters without service interruption. This fundamental shift allows for seamless relocation of virtual workloads across geographically separated or otherwise isolated installations. The result is unprecedented flexibility for scheduled maintenance, rapid load balancing, and the deployment of true multi-site management strategies.

Centralized SDN Capabilities and EVPN configuration
The platform provides integrated support for Software-Defined Networking, enabling centralized configuration of EVPN zones and Virtual Networks across multiple remote sites from a single interface.
Centralization of SDN settings eliminates disparate cluster configurations, drastically reducing administrative overhead and complexity in large-scale deployments. PDM ensures uniformity and facilitates the rapid, consistent scaling of the network infrastructure across the entire datacenter estate.
Written in Rust
Following the modern Proxmox roadmap, PDM is written in Rust.
- Performance: It is incredibly fast and efficient.
- Safety: Rust provides memory safety guarantees that reduce vulnerabilities.
-
Footprint: It requires very little RAM to run, which leads us to our next point...
PDM Remote Proxmox VE Overview
Where to Run PDM: VPS, LXC Container, or Local Server?
PDM is a lightweight, Rust-based tool that runs effectively almost anywhere. Savvy sysadmins choose an external VPS or a dedicated LXC Container for superior reliability and flexibility.
Here is why an external, neutral hosting environment is the preferred architecture:
The "Neutral Ground" Advantage
If PDM is hosted inside your primary cluster and the cluster fails, you lose your management tool when you need it most. Hosting PDM on an external VPS or container keeps your management plane online, allowing you to monitor and diagnose outages in your main infrastructure.
Security Isolation
The external host acts as a secure Bastion Host. You can configure your PVE node firewalls to only accept API connections from the PDM host's IP address. This significantly reduces the attack surface of your dedicated servers.
Cost-Efficiency and Low Footprint
Since PDM is written in Rust, it is extremely lightweight. You do not need a dedicated server. A standard VPS with 4 – 8 GB of RAM or a basic LXC Container is typically more than enough to manage a large infrastructure, providing excellent cost savings.
Recommended Server System Requirements
For reliable, stable operation and high performance of Proxmox Datacenter Manager in a production environment, Proxmox Server Solutions GmbH recommends the following specifications:
