Low PUE
PUE, standing for Power Usage Effectiveness, is a ratio that determines the level of energy efficiency of a data center. It is calculated by dividing the total power consumed by the data center by the power consumed solely by ICT equipment (servers, switches, arrays, etc.). A low value of this ratio is desirable, as this translates into a lower cost of electricity.
When designing, building and equipping further colocation facilities and server chambers in Atman Data Centers, we are mindful of achieving the highest possible energy efficiency. This is an important factor for us when selecting equipment and entire data center subsystems (such as HVAC air conditioning systems). As a standard, we use cold and warm aisle arrangements to make efficient use of server compartment cooling, which is the most energy-intensive component of data center infrastructure.
Reducing energy consumption in Atman DC
We actively support efforts to reduce energy consumption, including a long-standing participation in the European Commission’s program called European Code of Conduct for Energy Efficiency in Data Centres. As part of this program, among other things, we aim to raise awareness among our data center customers about efficient energy use and promote best practices among them. We provide advice to our colocation customers and help them choose energy-efficient solutions.
We are also constantly looking for opportunities to reduce the energy intensity of data center infrastructure, especially air conditioning systems. For example, several years ago, in consultation with customers of our colocation services, we increased the upper value of the temperature range we maintain in server chambers. This was based on our analysis of technological changes introduced by hardware manufacturers that lowered the environmental requirements of servers in this regard. Increasing the allowable temperature allowed us to reduce the cooling power and thus the energy consumption of the HVAC systems operating in Atman Data Center, while maintaining the SLA parameters guaranteed to customers.
