A green data center is a repository for the storage, management and dissemination of data in which the mechanical, lighting, electrical and computer systems are designed to maximize energy efficiency and minimize environmental impact. The construction and operation of a green data center includes advanced technologies and strategies.
The following are examples of some of the technologies and strategies used in green data centers:
Building and certifying a green data center or other facility can be expensive upfront, but long-term cost savings can be realized on operations and maintenance. Another advantage is the fact that green facilities offer employees a healthy, comfortable work environment. Green facilities also enhance relations with local communities.
There is growing pressure from environmentalists and, increasingly, the general public for governments to offer green incentives. Companies sometimes receive tax incentives and other types of monetary support for the creation and use of environmentally responsible technologies.
According to the Storage Networking Industry Association, energy consumption is one of the highest expenses of a data center. It is also among the top 10 issues that worry data center operators.
Adopting a green approach to data center energy and environment management can be a significant investment. However, over time, these data centers provide a range of advantages. Some benefits of green data centers are the following:
Two metrics have been developed to measure energy usage and sustainability. They are widely used to demonstrate and certify that buildings are using energy efficiently and don't harm the environment.
Developed in 1997, PUE measures the power consumption of a data center. It is the ratio of the power provided to the data center divided by the power the equipment in the data center uses. The goal is to have the ratio come as close as possible to one, which indicates effective power usage.
This metric was developed by The Green Grid, which is part of the Information Technology Industry Council. CUE helps confirm whether a data center has attained its sustainability goals. It is the ratio of carbon dioxide emissions the data center generates divided by the energy consumption of data center equipment. The goal is to have the lowest possible value, which indicates that the data center is effectively controlling its carbon dioxide emissions and carbon footprint.
Two certifications are available to validate that a building or IT device is energy-efficient and environmentally friendly:
Virtually every component of a data center, from how the building is constructed to the equipment in use, can be made more energy-efficient and environmentally friendly.
Whether upgrading an existing data center or building a new one, energy efficiency and environmental considerations are essential design components. Organizations planning a green data center can use a design firm with experience in designing energy-efficient and environmentally friendly buildings.
Design considerations and components of a green data center include the following:
