Homelab

Components

Since my homelab is constantly changing, it's likely that the information on this page is out of date. Generally, I don't change hardware that often. As of June 2026, I am running:

• 3x GF-1338NP-12 single-board computers in a Proxmox cluster
• A standalone Ubuntu 24.04 LTS server using extra parts.
• A 2023 Mac Mini with an Apple M2 CPU and 8GB of RAM.
• A Raspberry Pi 4 Model B with 4GB of RAM running Alpine Linux.
• 2x cloud VPSs for additional, external compute.

The Proxmox cluster is fairly new, so I am in the midst of transitioning most of my services to it. I am planning to install Proxmox on the Ubuntu server to make better use of its resources, and while I could install Proxmox as is, I'd rather start anew on that server. Currently, the Ubuntu server has an AMD Ryzen 3 3100 CPU, 32 GB RAM, and a NVIDIA GeForce GTX 1650 SUPER GPU.

All three of the GF-1388NP-12 boards have four Intel I225-V 2.5GbE interfaces. With four interfaces, it's easy to setup a routed mesh topology using direct connections between three nodes, for a cluster communication backbone. Since the topology requires \(n-1\) interfaces per node, we still have two interfaces left. I use one interface for management. The remaining interface's use is dependent on the node it's on. For one node, I have a virtualized OPNsense firewall. I passthrough the interface on that node to the firewall, which serves as my lab network's WAN port. On another node, I include the remaining port as part of a VLAN bridge that is on each node, so my personal computer can route through the lab network to my upstream router.
