Understanding Data Center Sustainability

Key Components of Sustainable Data Centers

Every aspect of a data center, from construction to equipment, holds the potential for improved energy efficiency and environmental friendliness. Efficient storage technology is crucial for a green data center. Explore the requirements for energy-efficient storage. Whether upgrading or building anew, prioritizing energy efficiency and environmental concerns is integral. Organizations opting for “green data centers” should engage design firms experienced in crafting energy-efficient and environmentally friendly structures.

Key Design Components:

• • • Cold and Hot Aisles: Strategic containment and placement of servers to optimize air circulation for cooling.
    • Free Air Cooling: Leveraging outdoor air in cooler climates to cool data centers.
    • Low-Power Servers: Efficient alternatives with lower energy consumption.
    • Modular Data Centers: Portable, quickly deployable, energy-efficient solutions, also known as “data centers in a box.”
    • Evaporative Cooling: Technologies like evaporation pads and high-pressure spray systems for heat reduction.
    • Heat Recovery and Reuse: Repurposing waste heat from data centers to warm other facilities.
    • Ultrasonic Humidification: Energy-efficient ultrasound technology required by specific data center devices for moisture generation.

Metrics for Evaluating Data Center Sustainability

Power Usage Effectiveness (PUE): Introduced in 1997, PUE measures a data center’s power consumption. It calculates the ratio of the total power supplied to the data center against the power consumed by its equipment. The goal is to achieve a close-to-one ratio, signifying efficient power utilization.

Carbon Usage Effectiveness (CUE): Developed by The Green Grid, CUE assesses a data center’s sustainability achievements. It computes the ratio of carbon dioxide emissions generated by the data center to the energy consumption of its equipment. Lower values indicate effective control of emissions and a smaller carbon footprint.

Certifications validating energy efficiency and eco-friendliness include:

• Leadership in Energy and Environmental Design (LEED): Established by the U.S. Green Building Council, LEED certification acknowledges buildings meeting stringent criteria for reduced energy consumption and environmental friendliness.
• Energy Star: Created by the U.S. EPA and DOE, this designation certifies energy-efficient products. Energy Star-certified items have collectively saved over 5 trillion kilowatt-hours of electricity since 1992, benefiting residential and business users.

Data center managers commonly employ specific metrics to gauge efficiency:

• • • Air Economizer Utilization Factor: Tracks the frequency of using outside air for free cooling.
    • Airflow Efficiency: Measures the effectiveness of air movement from supply to return.
    • ASHRAE Standards Compliant Cabinets: Evaluate progress toward ideal environmental conditions.
    • Carbon Usage Effectiveness: Evaluates overall data center sustainability.
    • CO2 Savings: Quantifies emissions avoided due to energy efficiency.
    • Delta-T Per Cabinet: Assesses airflow efficiency in cooling equipment.
    • Green Energy Coefficient: Measures onsite renewable energy generation.
    • Power Usage Effectiveness: Gauges total facility power dedicated to IT equipment.
    • Water Economizer Utilization Factor: Tracks frequency of indirect water cooling usage.
    • Water Usage Effectiveness: Assesses water efficiency in the data center.

Benefits of Using Sustainable Data Centers for Businesses

• • Next-Generation Storage Solutions: Industries like BFSI have witnessed substantial data growth, prompting the search for sustainable virtual data centers. These advanced centers offer cost-effective, scalable solutions to meet the escalating data demands of businesses, regardless of size or model.
  • Environmental Impact Reduction: Green data centers significantly curb energy consumption and environmental impact compared to their traditional counterparts. Implementing new energy-saving equipment and techniques in sustainable centers helps slash carbon footprints and environmental harm.
  • Enhanced Energy Efficiency: Virtual data centers exhibit superior energy consumption efficiency. IT teams can remotely monitor and manage equipment through virtualization, maintaining optimal conditions with minimal lighting and temperature fluctuations. Even slight temperature adjustments can yield significant energy savings.
  • Optimizing Server Usage: Traditional data centers often result in unused server space due to automatic allocation, leading to idle servers consuming power and resources. Green data centers mitigate this by effectively powering down unused servers, reducing energy costs and wastage.
  • Reduced Operational Costs: High power consumption in traditional centers increases operational expenses. Environmentally friendly data centers, with their efficient energy usage and power reclamation capabilities, minimize operational costs significantly through continuous monitoring and effective data management services.

Data Center Sustainability Challenges and Solutions 

The shift to an increasingly digital lifestyle has significantly increased online activity, leading to a surge in data center demand. The vast volume of video calls, streaming, and messaging apps have lifted data creation, posing challenges to managing this influx efficiently.

Data centers, the backbone of the Internet, consume substantial energy, with nearly 40% dedicated to cooling systems maintaining temperature-controlled environments around the clock. Estimates suggest data centers contribute up to 5% of global greenhouse gas emissions, emphasizing their environmental impact. Efficient cooling solutions become imperative as server racks emit heat while handling increased data, challenging the quest for a data center that requires one kilowatt of cooling energy for every kilowatt used by servers, owing to inevitable energy wastage and non-computing electrical installations.

Overcoming Obstacles in Energy Optimization

Efforts to decrease energy consumption and enhance sustainability involve various challenges:

• Investment in energy-efficient commercial chiller equipment aims to reduce energy usage and costs. This approach includes advanced chiller systems offering low-global warming potential refrigerants and optimized electricity consumption by 35%.
• Utilizing digital resources and analytics helps optimize energy usage by monitoring server load variations, identifying equipment issues, and minimizing unplanned repairs, potentially reducing these incidents by up to 66%.
• Challenging conventional temperature norms by operating data centers slightly hotter—within acceptable reliability margins—can yield up to 5% savings in chiller power consumption.
• Exploring sustainable energy sources like solar power to fuel data centers aligns with global sustainability initiatives. For instance, Singapore plans to quadruple its solar deployment by 2025, aiming for a significant portion of its energy consumption from renewable sources by 2030.
