Datacenter industries are aware of the term Power Usage Effectiveness (PUE). With the scaling data center industry, energy efficiency has now become a major concern. PUE is nothing but the key metric to measure the effectiveness of data centers in utilizing power. Certainly, lower PUE indicates good energy efficiency, But, do the data centers really have optimized Power Usage Effectiveness? Or is it still a challenge for several players in the industry? Further, we will learn how Immersion cooling is a great way to optimize Power Usage Effectiveness (PUE).

Understanding Power Usage Effectiveness (PUE): What does this key metric say about Data Centers?

The following formula is used to calculate PUE.

\[ PUE = \frac{Total Facility Energy}{IT Equipment Energy} \]

Please note that a PUE value of 1.0 represents perfect efficiency- indicating that all consumed power is dedicated to IT equipment without waste. However, traditional data centers often have PUE values between 1.5 and 2.5, with a significant portion of energy going toward cooling and infrastructure rather than computing.

Immersion cooling is a proven most effective way to optimize PUE. It is rather a revolutionary cooling technique that drastically reduces energy consumption and enhances overall efficiency.

Visarj is providing sustainable solutions that would help achieve optimized PUE.

So what are the challenges that the industry is facing in achieving Low PUE? Read next

Challenges in Achieving Low Power Usage Effectieness (PUE)

1. Inefficiency of Traditional Air Cooling

Conventional air-based cooling systems require complex HVAC setups**, fans, and air handlers, which consume excessive power. These systems often result in uneven temperature distribution, leading to energy inefficiencies.

2. High Energy Consumption from Cooling Systems

Cooling alone can account for 40-50% of total power usage in traditional data centers. Reducing this cooling energy consumption is essential to lowering PUE.

3. Thermal Limitations and Hardware Performance Issues

Thermal throttling resulting from traditional cooling solutions reduces computational efficiency. Conventional cooling does not work well with today’s highly demanding computations by AI and HPC workloads. This way it becomes difficult to ensure the perfect heat dissipation.

How Immersion Cooling Optimizes PUE

1. Direct Heat Dissipation with Liquid Coolants

Immersion cooling submerges servers in a non-conductive liquid coolant, which efficiently absorbs and dissipates heat directly from the components. Unlike air cooling, liquid cooling provides a **superior thermal transfer rate**, significantly reducing cooling power consumption.

2. Eliminating the Need for Air Conditioning

Since immersion cooling eliminates fans, chillers, and HVAC systems, it drastically lowers the overall facility power consumption. This results in a PUE close to 1.1 or lower, improving efficiency and sustainability.

3. Reduced Energy Wastage

Immersion cooling eliminates the chance of energy wastage. This way the power empowers IT equipment and thus the whole system becomes energy efficient. While traditional airflow systems or other inefficient cooling solutions do not control the wastage of energy.

4. Increased Hardware Lifespan

immersion cooling takes care of hardware stress by maintaining consistent temperatures. This feature gives more power to hardware and reduces replacement costs. Thus, it increases the lifespan of costly hardware and provides sustainable solutions.
