What is PUE equal to?

PUE is the ratio of total amount of energy used by a computer data center facility to the energy delivered to computing equipment. PUE is the inverse of data center infrastructure efficiency (DCIE). An ideal PUE is 1.0. Anything that isn’t considered a computing device in a data center (i.e. lighting, cooling, etc.)

What is a function of PUE?

PUE (Power Usage Effectiveness) is an indicator for measuring the energy efficiency of a data centre. In other words, PUE evaluates the energy performance of the data center by calculating the ratio of the energy used as a whole as compared with the energy used by just the IT equipment alone.

How can I reduce my PUE?

If the outside air is cool enough, use it to cool the facility and improve your PUE. Reduce power loss by using high-efficiency UPS systems to improve power distribution and eliminate unnecessary voltage conversion. Adopt controlled lighting technology. Turn off the lights when no one is in the facility.

How is PUE calculated?

Having a facility that uses 100,000 kW of total power of which 80,000 kW is used to power your IT equipment, would generate a PUE of 1.25. The 100,000 kW of total facility power divided by the 80,000 kW of IT power. DCiE Example: The 80,000 kW of IT power divided by the 100,000 kW of total facility power.

What is PUE and how is it calculated?

How is data center PUE calculated?

PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1.

What steps can you take in ensuring that a data Centre has low PUE?

Bigger isn’t always better

• Measure power usage.
• Improve airflow management.
• Regulate airflow / prevent hot and cold mixing.
• Align hot and cold aisles.
• Reduce airflow leaks.
• Check flooring.
• Introduce aisle containment.
• Control air temperature.
