# Hardware Compatibility Matrix

## Tested Platforms

| Platform | CPU | RAM | Storage | Status | Notes |
|----------|-----|-----|---------|--------|-------|
| HP ProDesk 400 G4 | Intel i3-8100T (4c/4t) | 16GB DDR4 | 1.8TB NVMe | **Certified** | Primary dev/test node (.228) |
| Generic x86_64 | — | 8GB | 457GB | **Certified** | Secondary node (.198), memory-constrained |

## Planned Platforms (Untested)

| Platform | Architecture | Expected RAM | Notes |
|----------|-------------|-------------|-------|
| Intel NUC 13 Pro | x86_64 | 16-32GB | Compact, NVMe, good for home server |
| Raspberry Pi 5 | ARM64 | 8GB | ARM64 build exists (docs/arm64-build.md) |
| Mini-PC (N100) | x86_64 | 8-16GB | Low power, fanless options |
| Lenovo ThinkCentre M720q | x86_64 | 16-32GB | Used market, reliable |

## Minimum Requirements

- **CPU**: 2 cores (4 recommended for 30+ containers)
- **RAM**: 4GB minimum (Core tier only), 8GB recommended, 16GB for all apps
- **Storage**: 500GB minimum (Bitcoin blockchain ~600GB), 1TB+ recommended
- **Network**: Ethernet (WiFi not recommended for servers)

## Known Platform Quirks

### .198 (8GB RAM)
- Crash recovery takes 260s (sequential container restart on limited RAM)
- Swap required (4GB minimum) to prevent OOM
- Background crash recovery (PERF-01) essential for health endpoint availability
- Backup with Argon2 KDF slow without adequate free RAM

### ARM64 (Raspberry Pi)
- Container images must be multi-arch or ARM64-specific
- Bitcoin Knots ARM64 image available
- Some containers (OnlyOffice) have no ARM64 build — must be excluded
- USB boot requires special ISO preparation
