Why do data centers use so much energy?

There are a few reasons why energy use is so high – and growing – in data center environments. Not only do servers and other critical pieces of IT equipment require a lot of energy to work, so too do all of the ancillary equipment. Lights, cooling systems, monitors, humidifiers, etc.

What is PUE and why is IT important?

Measurements of efficiency such as PUE helps data center owners/operators gauge their overall operations; as well identify opportunities to increase efficiency. A lower PUE rating means a more efficient data center, which in turn means lower operating costs for both the owner/operator and customer.

How is PUE calculated in data center?

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 in a data center?

PUE is the ratio of the total amount of power used by a computer data center facility to the power delivered to computing equipment.

How much energy does a data Centre use?

John Booth, managing director of consultancy Carbon3IT, estimates datacentres, including colocation facilities, account for at least 12\% of UK electricity consumption, or 41.11TWh a year.

How PUE is affecting the utilization of energy?

Quite simply, a data center with a high PUE score is consuming more energy than it should and is therefore less efficient. If a facility has a low PUE score, its total power usage is much closer to the energy demands of its IT equipment, which means it is more efficient.

What value of PUE should data center managers strive for?

Data center managers should strive for a PUE of 1.00. It is an important place to start because it allows Google to measure the change of usage effectiveness. 2. Describe the five methods recommended by Google for reducing power consumption.
