The scenario
A three-node Proxmox VE cluster uses two redundant core switches and a perimeter firewall. Backup traffic is isolated on a dedicated VLAN connecting to a Proxmox Backup Server.
What is in this drawing
Read the decisions behind it.
01
Dual core switches for redundancy
02
Dedicated backup VLAN (40) for Proxmox Backup Server
03
Trunk ports carrying management, migration, and storage VLANs on node links
Reusable for designing or documenting small to medium Proxmox VE clusters that need separate backup traffic and high availability switching.
