Green computing is a hot topic these days and is transforming the way we think about data centers. Businesses need to get serious about deploying green data centers for their processes and how they can save the environment along with reducing the Capital Expenditure (CAPEX).

The top metrics for evaluating a data center include aspects such as the strength of security infrastructure, computational power efficiency, and the speed of operation. However, opting for the data center with the right ecosystem has now become an essential aspect for organizations.

The infographic below illustrates the need for a Green data center and how a traditional data center can be converted to the green one.

What is a Green Data Center?

A green data center is a facility similar to a regular data center that is used for hosting a group of servers. However, the difference lies in the method of operation.

A green data center focuses on causing minimum impact on the environment and delivering maximum energy efficiency. Such data centers are entirely built and managed on green computing standards.

Why It Matters?

  1. Saves energy: Green data centers are designed not just to save energy, but also to reduce the requirement for expensive infrastructure to deal with cooling and power demands.
  2. Saves money: Green data centers use the latest techniques which consume less power. This helps in the reduction of both operational and capital expenditure for organizations, helping them save money.
  3. Supports environmental sustainability: Green data centers ensure that the impact of computing hardware has a lesser impact on the environment, thus helping to create a sustainable environment.
  4. Improves social and corporate image: By meeting compliance, regulatory requirements and regulations in corresponding regions, green data centers help organizations improve their corporate and social image.
  5. Utilizes resources better: Green data centers better utilize various resources like power, physical space and heat in an eco-friendly way.

How to Make a Data Center Green?

Below are some of the best practices to adopt a green data center.

  1. Consolidate your servers: Make a few basic changes to the existing data centers. Using virtualization technology in your data center can help reduce the number of physical servers. Fewer physical servers lead to less utilization of energy.
  2. Switch to energy-efficient servers: Making a switch to green IT principles can help you optimize performance and efficiency.
  3. Upgrade to high-efficiency power supplies: Inefficient power supplies can result in half of the power getting wasted before it even gets to the equipment. Moving to energy-efficient power supplies can save both capital and operating costs.
  4. Redesign cooling system: To reduce energy consumption, redesign data center to an improved cooling system which incorporates outside air.
  5. Redesign air management: Redesign air management to avoid recirculation of hot air from equipment and reduce bypass airflow.
