Intelligent Energy Management Made Simple
Cooling problems
• Server manufacturers specify inlet air temperatures
• Conventional controls don’t measure it
• Overcooling
• Inefficiency
• Hot spots
Cooling control is difficult
• Open plan design
- All cooling units affect all areas
• Redundant cooling units
- Can lead to “fighting”
• Custom control software is expensive and unreliable
- Can’t have a PhD commission every datacenter
