"The migration from per-node VLAN config to Proxmox SDN cut our network change time from days to minutes — and made the network reviewable."

Network Architect, Hosting Provider, DACH

Proxmox SDN

A software-defined network that scales with your cluster.

Forget per-node bridge configurations and VLAN drift. Proxmox SDN lets you define networks centrally — VLANs, VXLAN overlays, BGP-EVPN fabrics — and distribute them automatically to every node. We design and operate SDN fabrics for multi-tenant, multi-site, and KRITIS-grade environments.

ESXi-import natively supported in Proxmox since 7.4.

Migration runs in waves — risk is bounded per wave.

Veeam replacement and NSX-equivalent included in scope.

What Sets us Apart

3 nodes × 10 networks = 30 things that must stay in sync.

Without SDN, every cluster node maintains its own bridge, VLAN, and firewall configuration. Adding a node means replicating 10–30 entries by hand — and hoping they don't drift over time.

Without SDN

1

Node 1

vmbr0, vlan10, vlan20… (10 entries)

2

Node 2

vmbr0, vlan10, vlan20… (10 entries)

3

Node 3

vmbr0, vlan10, vlan20… (10 entries)

With Proxmox SDN

Define 1 zone (e.g., VLAN-aware) once, cluster-wide

Define 10 VNets inside that zone

Proxmox propagates configuration to every node automatically

Common questions

SDN FAQ.

Lorem ipsum dolor sit amet, est mollis iuvaret officiis ne, magna idque mentitum ei nec, iisque convenire similique cu sit.

Does SDN replace our existing physical fabric?

No. Proxmox SDN sits on top of your existing fabric. It abstracts the configuration layer, but VXLAN traffic still needs IP transport between nodes — usually 10/25 GbE.

What's the network requirement for VXLAN overlays?

10/25 GbE recommended for production, with ideally a dedicated VXLAN transport network. Latency between sites should stay below 10 ms for live migration to work cleanly.

Can we do EVPN without dedicated route reflectors?

For small fabrics (under ~10 nodes) iBGP full-mesh works. Above that, route reflectors significantly simplify the control plane. We design either model based on your scale.

Does SDN work with HA and live migration?

Yes, fully integrated. A VM live-migrated to another node retains its SDN VNet membership. EVPN distributed gateways even allow gateway failover at Layer 3.
