Executive Briefing (TL;DR)
- This article is brought to you by CoolIT, an Ecolab Company.Beyond 250 kW a server rack can no longer be cooled by a hybrid approach of liquid and air
- At this density a 70/30 liquid-air split leaves 75 kW of air load
- The air cooling system needed to move it brings cost and complexity few operators will accept
- The answer is near-total heat capture
- Liquid takes effectively all the heat, air falls below 1 percent of the load, allowing the server to run fanless.CoolIT builds these loops today fr
