Choosing the Right Hardware

Cluster Design and Requirements

For this lab, I opted for a three-node Nutanix cluster to explore advanced features and ensure high availability. Each node integrates compute, storage, and networking, replicating the design of a production-ready hyperconverged environment.

Minimum Requirements per Node

• Storage Devices:
  1. NVMe SSD for the Distributed Storage Fabric (DSF) cache
  2. SATA SSD for data storage
  3. USB drive (64 GB) for the hypervisor installation
• Hardware Requirements:
  • 16 GB RAM minimum
  • 4 cores / 8 Threads minimum

Hardware Selection

After thorough research, I chose the ACEMAGICIAN AM06PRO Mini PC for each node.

Key Features

• Processor: AMD Ryzen 7 5700U (8 cores, 16 threads, up to 4.4 GHz)
• Memory: 32 GB DDR4 RAM
• Storage Options:
  • NVMe SSD (512 GB, included)
  • Additional SATA SSD support
  • USB-C ports for flexible power options
• Networking: Dual Ethernet ports (1 Gbps and 2.5 Gbps)

Advantages of this Setup

1. Small Form Factor: Minimal space requirements
2. Energy Efficiency: Low power consumption
3. Low Noise: Suitable for home office
4. Expandability: Multiple storage options
5. Future-Proofing: 2.5 Gbps network support

Network Equipment

• Switch: TP-Link Gigabit Switch
• Current Speed: 1 Gbps (sufficient for basic lab)
• Upgrade Path: 2.5 Gbps switch compatibility for future expansion

Storage Devices

• NVMe SSD: Samsung SSD 990 Pro
• SATA SSD: Samsung SSD 870 EVO
• USB Drive: SanDisk Ultra Fit 64 Go

Router

In order to make this cluster independent and have control over the entire infrastructure, I add a front router.

• Router: HUNSN Micro Firewall Appliance

Custom Enclosure: Design and 3D Printing

To keep the setup compact and visually appealing, I designed a custom 3-node cluster enclosure using Fusion 360 and printed it with a 3D printer. Here’s the process:

Modeling in Fusion 360:

The design accommodates three ACEMAGICIAN AM06PRO Mini PCs stacked vertically. Ventilation holes are included for cooling, ensuring airflow for all nodes.

Printing the Enclosure:

The model was printed in PLA for durability and ease of use. Printing time: approximately 35 hours in total, depending on the 3D printer used.

Assembly:

The PCs fit snugly into the enclosure. I added labels for easy identification of nodes and ports. This enclosure not only organizes the hardware but also creates a professional appearance for the lab. It’s a satisfying addition for anyone who enjoys DIY projects alongside IT experimentation.

Design Specifications

• Software: Fusion 360
• Material: PLA
• Print Duration: ~35 hours

Features

1. Vertical stacking for three nodes
2. Integrated ventilation system
3. Cable management solutions
4. Node identification system
5. Professional appearance
