CASE ANALYSIS
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.
Key decisions
- Dual core switches for redundancy
- Dedicated backup VLAN (40) for Proxmox Backup Server
- Trunk ports carrying management, migration, and storage VLANs on node links
When to reuse this
Reusable for designing or documenting small to medium Proxmox VE clusters that need separate backup traffic and high availability switching.
