Deliverables on PUE investments.
During the process of adjusting your data centre infrastructure and trying to lower your PUE figure, you will ultimately reach a point where the investments won’t be fully offset by the financial benefits of a targetted PUE result. In other words, there is a break-even point within every achievement towards lowering your PUE figure. A break-even point differs from situation to situation. Basically, there are mainly three parameters with which you can determine your own personal break-even point.
These 3 parameters are:
The closer you get to the level of ”PUE=1.0″, the more effort it will take to further improve your PUE results. They asymptotic effect means that you will eventually come to a break-even point where further investments in PUE improvement won’t pay off anymore. Where the break-even point lays, is different for each and every situation. It also depends on the intended payback time. The longer this scheduled period is, the more investments you are able to make and the more chances you get to lower your PUE any further.
Generally speaking, stretching the payback time a bit will pay of in terms of energy efficiency and energy cost reduction.

In this whitepaper PUE specialist Niek van der Pas, working at the R&D department of Minkels, will share his knowledge. He will point out tips & tricks for the right use of a PUE metric, in order to reach a certain level of operational excellence within your own data centre environment. This whitepaper is meant for being used at the level of corporate server rooms as well as commercial data centre level. You can request a copy of our new whitepaper here and every week we will post a new tip at our blog.
