Seven nodes, a public ASN, and a tape library — the full inventory of the lab that runs at home.

compute

Seven nodes of RKE2

A full Kubernetes cluster on seven RKE2 nodes, managed by a Rancher deployed in the cloud. Ceph provides the base storage layer: 7TB of raw NVMe.

workloads

What the cluster runs

Prometheus and Grafana for monitoring, private PHP applications and their databases, and a full private media stack.

storage & backups

34TB, then cloud, then tape

A dedicated storage node holds 34TB raw for media and backups. Bacula runs the rotation — to the cloud, and to a tape library for offline copies.

network

BGP with a real ASN

OPNsense handles routing and firewalling; L3 switches with PoE and Cisco wireless — a WLAN controller plus APs — carry the traffic. The lab peers over BGP with its own publicly registered ASN, AS213367. A secondary test network sits behind an HPE router.

power

Conditioned, switched, measured

A dual-conversion UPS conditions the power, feeding a fully switched and monitored PDU.
