The Importance of Energy Efficiency in Server Power Supply Units
When it comes to running a data center, one of the biggest concerns is energy efficiency. Not only is it important for the environment, but it also has a significant impact on cost savings. One area that is often overlooked when it comes to energy efficiency is the power supply unit (PSU) of a server.
A PSU converts the alternating current (AC) power from the wall outlet into the direct current (DC) power that a computer needs to run. However, during this process, some energy is lost in the form of heat. This is known as the efficiency rating of a PSU.
The efficiency rating is expressed as a percentage and indicates how much of the energy is actually being used to power the computer. For example, a PSU with an efficiency rating of 80% means that 20% of the energy is being lost as heat and not being used to power the computer.
This might not seem like a big deal, but when you multiply this by hundreds or thousands of servers, it quickly adds up. In fact, according to Google, PSUs can account for up to 33% of a data center's overall energy consumption.
So, what can be done to improve energy efficiency in PSUs? One solution is to choose hardware that has a higher efficiency rating. For example, a PSU with an efficiency rating of 90% will use less energy and generate less heat than a PSU with an efficiency rating of 80%.
Another solution is to implement power management techniques, such as power capping or power throttling, which can help reduce energy consumption during periods of low demand. Additionally, using renewable energy sources, such as solar or wind power, can further reduce the impact on the environment.
At Leaseweb, we understand the importance of energy efficiency and have made it a priority in our data centers. We carefully choose hardware that has a high efficiency rating and regularly monitor energy consumption to identify areas where improvements can be made.
In conclusion, energy efficiency in server power supply units should not be overlooked. Choosing hardware with a higher efficiency rating, implementing power management techniques, and using renewable energy sources can all help reduce energy consumption and save costs in the long run. By working together and sharing best practices, we can continue to make strides towards a more sustainable future for data centers.
