Three-node Proxmox cluster with dedicated network segments for VM traffic, storage replication, and out-of-band management via Dell iDRAC IPMI. Internet-facing Proxmox VE hosts connect through a 10Gb/s main switch, while an isolated IPMI switch provides secure node management independent of production networks. Each node runs local ZFS storage and hosts multiple guest VMs across vmbr0 and vmbr1 virtual bridges, with a dedicated Proxmox Backup Server for cluster-wide data protection. This architecture isolates management, compute, and storage traffic to minimize latency, prevent blast radius, and enable non-disruptive cluster maintenance. Fork and customize this diagram on Diagrams.so to match your hardware specifications, VLAN assignments, or add additional nodes and storage targets. The separation of IPMI management from production networks follows infrastructure best practices for secure remote access and disaster recovery.
