Data Center Configuration

Configure IT Component Cooling (Per Node)

Toggle 'Coolable' components between Air and Liquid cooling. Non-coolable components remain air-cooled.

IT Component A1 (e.g., Primary CPU/GPU)

Always Air Cooled

IT Component B1 (e.g., Accelerator)

IT Power: 533W

Fan Power (if Air Cooled @25°C SAT): 173W

Currently: Air Cooled

IT Components B2 & C (e.g., Drives/Other)

Always Air Cooled

Typical Node Profile & Baseline Power

Typical Real-Life Server Example: The IT nodes simulated here, with an IT power of approximately 8.46 kW, are representative of modern high-performance servers.

These are often multi-GPU systems (e.g., NVIDIA DGX-like servers or similar) designed for AI/ML training or HPC. The dominant "IT Component A1" (5.2 kW) likely represents such a GPU subsystem.

The remaining power accounts for powerful CPUs, RAM, networking, and storage. Such high power density makes them prime candidates for direct liquid cooling.

Data Center Fan Power Comparison (200 Nodes)

The "Baseline Fan Power (DC)" of 168.0 kW assumes all IT components are air-cooled. This is derived from: 200 nodes × 840W/node (fans @25°C SAT) = 168.0 kW.
