data center power tips
by Josh Schaap
Over the past couple of posts (Part 1, Part 2), we’ve looked at some best practices for power density and voltage as well as environmental monitoring in the IT equipment racks. In this final installment, we’ll examine power usage and the measuring of energy efficiency. When you measure data center energy efficiency, you’re really monitoring power usage in order to reduce wasted energy. For nearly the past decade, the PUE (Power Usage Effectiveness) and DCiE (Data Center Infrastructure Efficiency) ratings have been the gold standards for measuring efficiency within data centers. Although with ASHRAE 90.4, PUE has been phased out as an acceptable metric for data center power efficiency. At the individual data center level, the end goal of these methods is to help you better measure your power usage so you can start the process of improving your energy efficiency and realizing cost savings for your data center.

In the last post, we explored a pair of tips related to power density and voltage, including the use of three-phase power over single-phase and providing increased voltages to your equipment. This week, we’ll dive into power and environmental monitoring in the IT equipment racks. These days, data centers are constantly dealing with an increase in the number of devices within individual racks. Along with higher operating temperatures, this has led to the need for a careful approach to ensure there are very few – if any - costly interruptions in service.

Some things in life just don’t come with a handbook: raising children, navigating the job market, deciding what to do with your life. These things require a combination of on-the-job-training, intuition, planning and luck. Fortunately, when it comes to data center management, the job is as much science as it is art. In this series, we’ll cover some of the fundamentals every data center manager needs to know when it comes to power.
