GL.iNet Comet Q (GL-RMQ1): Strengths & Caveats
✔ Advantages
- Driverless 2K QHD 60 FPS remote KVM video capture with integrated USB-C DisplayPort Alt Mode
- Integrated 1.8-inch touchscreen color LCD displays real-time connection status and IP address
- Native Tailscale and ZeroTier mesh VPN integration enables remote access without firewall port forwarding
- USB-C power passthrough keeps controlled host devices charged during active remote administration
✖ Documented Caveats
- Target host device strictly requires USB Type-C DisplayPort (DP) Alt Mode support
- Wi-Fi link throughput ceiling is capped at 286 Mbps
Zella DC Zella Stack: Strengths & Caveats
✔ Advantages
- Modular stackable block architecture enables standard courier delivery and elevator transport without heavy rigging equipment
- Scalable rack framework accommodates 24RU to 48RU configurations in 12RU increments
- Supports concurrent air and liquid cooling architectures with aggregate heat dissipation up to 124kW
- Integrated Zella Sense telemetry platform provides extensive environmental sensing, security cameras, and automated monitoring
✖ Documented Caveats
- Dedicated cooling sub-assemblies occupy 6RU to 12RU of internal space, reducing usable IT capacity to as little as 9RU
- Realized cabinet weight savings (28% to 47%) fall short of the advertised 75% reduction over predecessor models
