Power efficiency in the datacenter
• Power Usage Effectiveness (PUE)
• How much of total datacenter power is not used for IT?
• Cooling infrastructure, UPS, power , …
• Ideal value is 1.0
• Does not say anything about IT power efficiency
• IT Usage Effectiveness (ITUE)
• How much IT power is not used for computing?
• PSUs, fans, voltage regulators, …
• Ideal value is 1.0
• Does not say anything about datacenter power efficiency
• Total-Power Usage Effectiveness (TUE)
• How much datacenter power is not used for computing?
• TUE = PUE * ITUE
• Ideal value is 1.0
• Energy Reuse Effectiveness (ERE)
• How much power is lost to the universe?
• Ideal value is 0.0.
• Equal to PUE if no reuse

Why use water to move the heat away?
• Energy (Joules)
1 Joules is the energy required to
– Let the human heart work for 1 second
– Lift a chocolade bar (100g) by 1 meter (g=9.81 m/s²)
– Let electrical power of 1 W flow for 1 second
