organizations investing in ‘greening’ their data centers, efficiency and power usage effectiveness (PUE) will soon become
a major focus.
PUE measures how
efficiently a data center uses energy; especially when it comes to computing
equipment -- in contrast to cooling and other overhead infrastructure. It has become the industry’s
preferred metric for measuring data center infrastructure efficiency.
data center’s efficiency is the first step toward reducing power consumption and
related energy costs. This enables you to understand the current level of
efficiency in the data center. As you implement additional efficiency best
practices, it also helps you change the effectiveness of those efficiency
PUE across the regions and countries is difficult because there are many
variables within each environment. According to a Data Center Knowledge Special Report, for example, many data center
operators in Scandinavia have been able to achieve PUE as low as 1.3 (the
average is 1.9). This is possible since they make the effective use of free cool air available in their
hot and humid, has been increasing its efforts towards lowering its PUE. Some
of the large production data centers have achieved a lower PUE and are now
targeting an overall average PUE of 1.3 within next few years. This proves that
with the right approach, reducing the PUE is possible even in the extreme heat
Of course, with the
“greening” of data centers, there are other factors that affect PUE. We’ll
analyze some of them in the second part of this blog series. Stay tuned. In the
meantime, what is the PUE in your data center?
