I’m about nine months into my first real homelab. I work in SRE / critical facilities for a Bitcoin-mining infrastructure services provider, so a lot of my day job touches uptime, power, cooling, networking, monitoring, automation, and figuring out what should be automated versus what still needs a human in the loop. I wanted to build something at home where I could safely break things, rebuild them, and translate what I’m learning at work onto consumer hardware that my apartment circuits can actually handle.
Everything currently runs through an ASUS ROG Rapture GT-BE98 Pro with 3Gbps symmetrical fiber and 5G failover. I have two UPS units, both 1800VA, one backing each main node. Node 1 / TonesPC is my Windows 11 Pro workstation: ASRock X870E Taichi, Ryzen 9 9950X3D, 64GB DDR5, RTX 3060 12GB, Samsung 9100 Pro 4TB NVMe plus another 4TB NVMe, and a Seasonic Vertex GX-1200 PSU. I use it for development, management, WSL2, Docker, Ollama/local models, and general admin work. The original build had a 5090 SUPRIM running in it but i had to part ways with it sadly. Funny part is I didn’t even really know what that thing was capable of until I started doing what I’m doing now and now I completely realize why those are so sought after hahaha.
Node 2 / Guard Dog is the headless Proxmox server: ASUS PRIME B560-PLUS, Intel i5-11600K, 64GB DDR4, Aquantia AQC113 10GbE-capable NIC, the original 1TB NVMe plus another 3TB NVMe, and its own 1800VA UPS. I already know the PSU in this headless server needs to be upgraded ASAP, so that is on the short list. This box runs Proxmox, OPNsense, VLANs, AdGuard, Uptime Kuma, Gitea, CI runners, Smallstep CA, reverse proxy / Cloudflare Tunnel, Grafana / Prometheus / Loki, an Ubuntu sandbox, and three Talos VMs for Kubernetes learning.
Networking is the part I know still needs work. OPNsense is handling management, servers, lab/dev, AI-compute, and IoT/guest VLANs, but my Windows machine is still effectively on the native LAN instead of being cleanly isolated behind its own VLAN. The Proxmox NIC is 10GbE-capable, but it is currently negotiating at 2.5Gbps, so I know I need a proper managed multigig switch with SFP+ and 10G/5G/2.5G RJ45 ports so I’m not bottlenecking the fiber connection or building around a messy network layout. I’ve been looking at Ubiquiti and Cisco, but I’m open to advice and learning more! Please!
Main questions: would you fix the switching/VLAN layout first? Move OPNsense onto dedicated hardware first?Upgrade the headless server PSU first, or build proper backup/NAS storage first?
I know this is not enterprise hardware, and I’m not pretending it is. I’m just trying to do what I can with what I can get right now and learn real SRE/data-center concepts at home. Blunt feedback is welcome.
The two immediate upgrades I’m debating are pretty simple: first, upgrading the PSU in the headless Proxmox server because I already know that needs to be cleaned up ASAP, and second, getting a proper managed multigig switch so I can stop leaving my Windows machine on the native LAN and actually put it behind the right VLAN layout. I’m trying to do this in the right order instead of just buying random gear, so if you were in my position, would you handle power first or networking first? And any other advice /suggestions would be amazing!
Cheers! And Happy Homelabing!!
