• Cooling Load Is the Major Part Of The Power Consumption • Major Heating Sources In Data Center Are Processors &
Optimize Air Management
Optimize Air Management
• Calculate The Critical Heat Load
• Depends The Equipment Deployed In The Room In Addition To The Heat Transferred From The Surrounding, Lighting And Other Sources Of Heat
• Estimate The Flow Requirement For Cooling The RLU
• Estimate The Power Density Based On RLU Cooling Rate
• Establish Room Cooling Strategy
• Based On The Space Availability And The Arrangements Of All The Ancillary Equipments In Addition To The Server Racks
• Determine The Cooling Methodology
• Based On Available Facility And The Easiness
• Heat Rejection And Cooling Redundancy
Right Sizing Of The Datacenter
Right Sizing Of The Datacenter
• Fixed Losses
• Irrespective Of The IT Load There Are Losses Due To Physical Infrastructure Equipments
• Over Sizing Of Physical System
• Use Of Modular, Scalable Physical Infrastructure Have The Flexibility To Add When Additional IT Load Is Needed
• Better Prediction Of Future Need
• The Need Of The Future Expansion For The Organization Should Be Planned Properly
• Adaptable To New Technology
• The New Servers With More Heat Generation Should Also Be Considered
• Determine The Computing Source Required And Estimate The Capacity
