GL.iNet Comet X (GL-RM4PE): Strengths & Caveats
✔ Advantages
- Four-channel remote KVM capability allowing simultaneous management of up to four systems
- Power over Ethernet (PoE) combines power and network connectivity into a single cable feed
- Integrated touchscreen interface allows direct hardware monitoring and channel control
- Compact rackmount form factor with solid build quality and reliable port retention
✖ Documented Caveats
- Lacks integrated Wi-Fi support, requiring a dedicated wired Ethernet drop
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
