Energy Efficient Data Centre Cooling There is no one single best cooling solution for all Data Centres
Energy Efficient Data Centre Cooling Constraints Fundamentals Solutions Management
Energy Efficient Data Centre Cooling Data Centres use 3% of total UK Electricity A/C power use 2 nd only to servers Accepted Energy Efficiency Metric (PUE)
Constraints Budget Design Parameters Rack Power Density Energy Efficiency Total Cooling Requirement Internal Space Maintenance External Space Noise Criteria Local Environment Water Source Personal Preference Any other influencers
Fundamentals Direct the cold air Segregate hot and cold aisles Ensure air paths are only through the servers Create a clear path for the hot air return Adjust temperature set points correctly Adjust humidity settings Look for free cooling opportunities
