October was one of the most intense, productive months in Core Lab since I started documenting self-hosted infrastructure. The weather wasn't even that bad?! Between migrating my live server operating system and 70 Docker containers over to internal NVMe storage, hardening my perimeter firewall automation, launching the brand new Core Lab Hardware Store, and publishing a **deep bench of production guides**, there is a mountain of fresh engineering to share. Here is a complete rollup of the newest guides, architectural lessons, and infrastructure upgrades hitting the site since my September update. You can also read the previous edition here: [**News from Core Lab: Summer is Over (Sept '26)**](https://corelab.tech/news-sept26/). --- ## New Production Guides Published Since September ### 🌐 My 2026 Homelab Networking Stack: OPNsense, UniFi & 10GbE - A full architectural breakdown of the physical Core Lab networking rack. I walk through my bare-metal OPNsense edge firewall with 2.5GbE WAN, silent UniFi USW-24 Layer 2 distribution switching, ceiling-mounted UniFi U6 Pro Wi-Fi 6 coverage, and the fanless Binardat 8-Port 10G SFP+ optical backbone linking my compute and storage nodes at 0dB. 📡 Was in early-access for ****paid subscribers** \- made public 1 Nov! 😃 [My 2026 Homelab Networking Stack: OPNsense, UniFi & 10GbEA real-world walkthrough of my 2026 homelab networking architecture: bare-metal OPNsense with 2.5GbE WAN, dual UniFi Gen2 switches, 10Gbps SFP+ storage backhaul, and Dockerized controller management.![](https://corelab.tech/content/images/icon/Glowing_CPU-1-27ad7c93-8ba7-4cd3-b004-c818efc893dc.png)Core LabCore Lab Joe![](https://corelab.tech/content/images/2026/10/Core-Lab-Rack-v1.1.webp)](https://corelab.tech/2026-homelab-networking-stack/) ### 🔌 UGREEN USB 3.0 to 2.5GbE Adapter as an OPNsense WAN NIC - Can a sub-$25 USB network adapter handle a saturated 1.5Gbps symmetrical fibre WAN connection 24/7 without melting or dropping packets?

Instead of burying product recommendations inside thirty different articles, the new store brings together all my verified homelab hardware across curated category shelves: high-density chassis, 10G optical switches, firewall micro-nodes, QuickSync transcoders, and enterprise storage. Every card features localized smart links, verified technical specs, and strictly zero static price traps.

The root operating system (previously running on an external USB-SATA SSD) suffered from **UAS command-queuing stalls under *heavy* Linux I/O**. I migrated the entire OpenMediaVault root OS and my 70-container Docker stack to an internal Samsung 970 EVO Plus M.2 NVMe SSD using block-level dd cloning and warm background rsync transfers. The results have been *phenomenal*: container databases (Immich Postgres, Ghost MySQL, Paperless) saw immediate latency drops, and the per-stack downtime was held to under 60 seconds during final cutover. I am currently finalizing a complete, battle-tested step-by-step runbook detailing how to clone a live Debian/OMV OS drive and migrate Docker data-root with zero data loss. --- ## Coming Soon: ### The Dearly Departed: Homelab Edition 😥 > What to do with your homelab if/when you pass? Who should do what? When? How does your loved one even ***begin?*** This has been requested by more than 1 person so it's about 90% done! It'll be ready soon, published later this week. ### The 2026 Black Friday Homelab Playbook With November officially here, holiday sales promotions are starting to flood retail storefronts. Most Black Friday hardware guides are lazy copy-paste jobs designed to push whatever slow SMR hard drives or DRAM-less QLC solid-state drives retailers want to liquidate. I am putting the finishing touches on the 2026 Black Friday Homelab Hardware Playbook. This guide will give you explicit target '**Buy Below**' price thresholds in both Canadian Dollars (CAD) and US Dollars (USD), a built-in 'Homelab Trap Detector' to steer you away from catastrophic hardware bottlenecks, and direct links to the battle-tested equipment I run in my own lab (from Fractal Define 7 XL cases to 10G Binardat optical backhauls and GMKtec micro-nodes). Keep an eye on your inbox next week when it goes live! --- ## Core Lab Reader Survey: What Should I Tackle Next?
