Homelab Hardware Fleet Deployment

Overview

Strategic deployment guide for transforming a heterogeneous hardware fleet into a tiered, role-specialized infrastructure. Covers Mac Mini headless server conversion, Lenovo fleet revitalization (P330 Tiny, ThinkStation C30, M92p clusters), and the transition from hobbyist homelab to professional ops-core architecture.

Tiered Architecture

Always-On Core (P330 Tiny)

• Upgrade to 32GB RAM + 1TB NVMe SSD
• 8th Gen Intel for modern efficiency
• Handles critical infrastructure: reverse proxy, DNS, monitoring

Storage Vault (ThinkStation C30)

• Repurpose as centralized ZFS storage server
• ECC Registered DDR3 memory for data integrity
• High-capacity enterprise CMR HDDs for TrueNAS SCALE

Experimentation Cluster (M92p x3)

• k3s or Docker Swarm cluster for high-availability experiments
• Budget SATA SSDs sufficient for ephemeral workloads
• Isolated from production services

Build Mule (M4 Mac Mini)

• High-performance Apple Silicon for iOS development and builds
• OrbStack or Tart instead of Docker Desktop to reduce overhead
• Headless server conversion: SSH + Screen Sharing, disable sleep, automatic power-on recovery
• Separate OS from data via external USB4/Thunderbolt enclosures

Deployment Principles

• Infrastructure as Code: Every machine scriptable and recoverable from bare metal in <2 hours (Ansible/Terraform)
• VLAN segmentation: Isolate management, storage, and development traffic
• VPN-only access: Tailscale overlay network, no port forwarding
• 3-2-1 backup: ZFS snapshots + encrypted off-site replication
• Power optimization: Tiered architecture (always-on, burst compute, experimentation) balances efficiency
