Cloud Data Center Physical and Environmental Protection


  • monitor ambient conditions inside data center
    • temperature and humidity
      • important for optimizing operations and performance
  • capture average measurements across several thermometric devices throughout the airflow process
    • for realistic measurement
  • target metric standards are created by Technical Committee 9.9 of the American Society of Heating, Refrigerating an Air-Conditioning Engineers (ASHRAE)
    • offers detailed recommendations for various data center aspects
      • e.g., IT equipment, power supply, battery backups
    • General ASHRAE recommendations:
      • Temperature: 64º – 81º F (18º – 27º C)
      • Humidity: Dew point of 15º – 59º F (-9º – 15º C), relative humidity of 60%

Effects of Ambient Temperature and Ambient Humidity

  • ambient temperature that is too high can allow hardware to overheat
    • high-capacity electrical components generate a lot of waste heat
    • devices can be sensitive to conditions that exceed their operating parameters
  • ambient temperature that is too low can be a risk to health and human safety
    • touching bare metal at the freezing point can burn or remove skin
  • ambient humidity that is:
    • too high
      • promote corrosion of metallic components and mold
    • too low
      • enhance possibility of static discharge
      • increases risk of fire
      • can hurt personnel and equipment
