ABOUT

About these examples.

These diagrams are for sysadmins, DevOps engineers, and homelab enthusiasts planning or documenting a Proxmox VE cluster. All examples are fully editable; use them as starting points for your own environment.

HOW TO

Make one yourself.

  1. 1

    Identify cluster nodes and roles

    List every Proxmox node and note any special roles like QDevice, Ceph monitor, or backup server.

  2. 2

    Map physical and virtual network interfaces

    For each node, document NICs, Linux bonds, bridges, and VLANs used for management, migration, and storage traffic.

  3. 3

    Add switches and segmentation

    Place physical or virtual switches and show VLANs or separate fabrics to clarify traffic isolation and redundancy.

  4. 4

    Label IPs, subnets, and links

    Annotate each connection with IP addresses, subnet masks, and link speeds to make the diagram operationally useful.

  5. 5

    Review with your team and export

    Validate the diagram against your actual configuration, then export as PNG, SVG, or PDF for documentation or troubleshooting.

FAQ

Frequently asked questions

What is a Proxmox cluster network diagram?01
It's a visual representation of how Proxmox VE nodes are connected—showing NICs, bonds, switches, VLANs, and IP addressing for management, migration, and storage networks.
Why do I need a network diagram for my Proxmox cluster?02
A diagram helps you plan redundancy, troubleshoot connectivity issues, document your setup for team members, and quickly onboard new admins.
Can I create a Proxmox cluster network diagram for free?03
Yes, ChatDiagram offers free examples and an editor where you can modify diagrams, add your own nodes and links, and export without cost.
What software is best for Proxmox network diagrams?04
ChatDiagram is purpose-built for network diagrams; it includes Proxmox-specific examples and an intuitive drag-and-drop interface, so you can create accurate diagrams quickly.
How do I diagram a Proxmox cluster with Ceph networking?05
Separate the Ceph public and cluster networks onto different VLANs or physical fabrics, then show each node's bonded interfaces connecting to those networks. You can start from a 3-node HCI example and adjust.
