Our Cooling Journey The Evolution of Cooling Technologies at Digital Realty
7
A 12-YEAR HISTORY OF COOLING MISSION CRITICAL SPACES
• Initial data centers where inherited properties with traditional central chilled water plants
• First purpose built data centers featured dedicated air-cooled chillers
• Second generation were dedicated rooftop DX units with a plethora of variations – adiabatic, air-side economization, etc.
• Current third generation design features dedicated split systems with economization
• A number of our data center campuses feature multiple cooling technologies

OPTION #1
Advantages • Moderate initial cost • Low maintenance cost • Minimal indoor space requirements • Closed system • Simple operation • Very good PUE (economization)
Disadvantages • Requires large roof space area • Cannot be used in all climates • Higher peak energy requirements • Less flexibility with IT load density variations

OPTION #2
Advantages • Moderate initial cost • Low maintenance cost • Minimal indoor space requirements • Closed system not dependent on
make-up water • Simple operation
Disadvantages • Use of glycol for freeze protection
requires overall system de-rating • Not suitable for all climates • Moderate energy efficiency

OPTION #3
Advantages • Efficiency and operating cost • Large tonnage capabilities • Most flexible with IT load & density variations • Most flexible option for renovated buildings • Allows for simple installation of water-side
economizer
Disadvantages • High initial cost • Higher maintenance costs • Occupies significant indoor floor space • Make-up water for cooling towers
Customer Considerations What do end-users need and want?

KEEP IT COOL – ALL THE TIME
• Keep it cool – all the time – Commitment to the end-user is via
environment SLA’s – Structured around ASHRAE T9.9
guidelines – Penalties for exceeding temperature
or humidity ranges
• Make it as efficient as possible – End-user is paying the utility bill – Lowest possible PUE – Minimize OpEx
• Ultimately, the cooling technology is the choice of the data center owner and operator
