Day 15: A Cost-Effective Virtualisation Server
The Dream Server vs. Reality
I had that dream again—the one where I have an unlimited budget for computer hardware without the wife hovering over my shoulder! While I haven't quite built a J.A.R.V.I.S.-level AI server farm yet, I’m working on a very capable real-world alternative.
Why Do I Need a Server?
My current home lab is a 2012-era Mac mini that is really starting to show its age. It’s struggling to keep up with basic tasks, and I need a dedicated machine to centralize my home operations:
- Network Management: Moving to a unified management interface for my home network.
- Media & Storage: Replacing my aging NAS and USB drives with a centralized, reliable storage solution.
- Smart Home Hub: Managing locks, blinds, and lights locally via MQTT and Home Assistant to avoid reliance on unstable cloud services.
- Plex Media Server: Hosting my media with potential for live TV via DVB/Satellite cards and on-the-fly transcoding.
- Experimental Sandbox: Running virtual machines for testing, including potential macOS experimentation and offloading Blender rendering tasks.
The Hardware: HP ProLiant ML350p Gen8 V2
Instead of the £17,000 price tag of a top-tier Mac Pro, I’ve put together a robust rack-mount server from Bargain Hardware for a fraction of the cost:
- Processors: 2 x Intel Xeon E5-2697 V2 (24 cores total).
- Memory: 128GB DDR3 1600MHz (with plenty of expansion slots left).
- Storage: 480GB SSD (OS) + 20TB SAS HDD array (RAID).
- Networking: 10GbE SFP+ dual-port NIC for high-speed fiber connectivity.
- Expansion: Dual 1200W Platinum PSUs to support future PCIe cards.
Total Estimated Hardware Cost: ~£1,353.60.
With the addition of two Radeon RX 590 GPUs for rendering/transcoding, the total comes to £1,903.58.
The Software Strategy
I’m opting for a "bare metal" approach to virtualization to keep things efficient and modular:
- Hypervisor: Microsoft Hyper-V (free, reliable, and handles virtualization well).
- Network Management: Ubiquiti UniFi Controller for centralized network control.
- Storage: FreeNAS (separate from the main OS to ensure data integrity).
- Smart Home: Home Assistant (Hass.io) for local device management.
- Media: Plex Media Server running on an Ubuntu VM.
- Rendering: A dedicated Ubuntu instance to handle Blender render jobs, freeing up my MacBook Pro.
- Sandbox: Additional VMs for experimenting with macOS, Windows 10, and Linux distributions.
