5. Network Architecture & Management Tools
- 10Gbps Ethernet Backbone: High-speed wired links between main hosts for fast data transfer—vital for virtualization and editing large datasets.
- VLAN Segmentation: Strong isolation between storage, management, and dev/test improves security and troubleshooting.
- Netdata (All-Nodes): Unified, lightweight system monitoring across all devices, giving instant visibility and alerting for uptime and resource use.
- Tailscale WireGuard Mesh VPN: Seamless, secure remote access to every device on a single flat overlay network—easy to manage and highly secure.
Design Philosophy & Key Takeaways
- Redundancy: Multi-node clusters and dual WAN assure high availability and business continuity.
- Performance: Ample RAM, NVMe storage, and high-end GPUs empower VM flexibility, AI, and creative workflows.
- Efficiency: Low-power nodes keep costs down; powerful hardware only wakes when needed.
- Security: Defense-in-depth with pfSense, VLANs, and modern overlay VPN ensures peace of mind.
This hardware and architecture isn’t just a collection of tech—it’s an agile, future-ready foundation for productivity, experimentation, and private cloud learning. Strategic choices mean every device serves a purpose and delivers maximum return, whether you’re self-hosting, building AI models, or simply learning advanced IT at home.
