Data Centers Seeking Energy Efficiencies Have Options

By Ken Rapoport, CEO of Electronic Environments Corp.

Our advice to clients who engage us for assistance in building and retrofitting data center facilities for energy efficiency: consider the foundations upon which your data centers are built and the assets deployed inside them.  Reliability and energy efficiency are the overarching objectives.  This approach reinforces that the data center will perform to expectations in meeting the requirements of their business.

In scenarios where the client is building a new facility, the energy efficiencies offered by large cloud providers can be an attractive option to consider based on a number of factors.  For one, these providers can locate their facilities in geographic regions where the cost of energy is comparatively lower, for example in the northwest of the United States.  They can also leverage customized servers that are able to operate at higher temperatures and higher efficiencies.  Lastly, large cloud providers can take advantage of advanced scalability and uniformity capabilities.  The net result can mean levels of Power Usage Effectiveness (PUE) of 1.02 or 1.01 — a significant achievement.  However, a sizable number of businesses will not have these options, and therefore rarely achieve PUE levels of less than 2.0.

In order to reduce their PUE levels, EEC advises customers in several ways.  First, we conduct assessments and deploy advanced technologies — for example, energy-efficient mechanical systems that take advantage of free cooling.  The good news is that a number of powerful new technologies will deliver impressive returns and are available at comparatively low cost.  These include intelligent air distribution and management systems that can achieve energy usage reductions of between 20 and 40 percent in just two short years.

Another option that can deliver greater energy efficiencies is to retrofit your legacy data center technologies.  For example, if you’re operating a low-density data center, one that’s operating at 50 watts per square foot, you can deploy direct water-cooled racks or in-row cooling in zones in order to accommodate potential future zones of higher density servers.

Remediating Environmental and Energy Data Center Concerns with CRAC / CRAH Retrofit

By: Kevin O’Brien, President – Mission Critical Construction Services Division, EEC

We must address the environmental footprint current data center facilities have on climate change due to their immense energy consumption. Extensive industry research indicates that data centers presently consume approximately 3% of the world’s electricity, while emitting nearly 200 million metric tons of CO2.  As data centers continue their proliferation to support the growth of Internet of Things (IoT), Big Data, social media and cloud computing, their energy consumption and CO2 will only increase.  One cost-effective and reasonable method to decreasing the negative environmental impact and improving productivity within the data center is optimizing environmental parameters such as Computer Room Air Conditioning (CRAC) and Computer Room Air Handler (CRAH) units.

For the past 13 years, I have been personally involved with the implementation of more than 3,000 CRAC / CRAH units – both new and old.  Many of these older units can only modulate on and off, so they operate at constant volume all day, every day and consume enormous amounts of energy. In this case, newer models may need to be purchased as they possess the capability to modulate fan speeds in order to save energy thanks to built-in Variable Frequency Drives (VFDs).

However, purchasing new CRAC / CRAH may not be in the budget for many data center operators.  If this is the case, operators can still cost-effectively optimize the performance of existing systems by retrofitting CRAC / CRAH units with VFDs.  This can substantially decrease energy consumption and cost as simply lowering a fan’s speed by 20% can cut power requirements in half.  In my experience, I’ve learned that 2008 CRAC / CRAH units are the most cost-effective to upgrade with Emerson VFDs.  Couple this with the 20% to 50% energy savings potential of Direct Expansion (DX) and chilled water units, and you can save even more.  While savings will vary at each facility given specific IT load in the data room and equipment configuration, the ROI potential is worth the initial investment.  Another logical step to take during this time is to install an airflow monitoring system, which enables maximum energy savings thanks to reduced energy consumption and improved Power Usage Effectiveness (PUE).

Electronic Environments Corp. (EEC) is here to help you with your CRAC / CRAH unit retrofit and airflow monitoring system projects as well as a wide array of preventative maintenance.  By monitoring the inlet and outlet rack temperatures alongside the return air entering the CRAC unit, EEC can also help you match your underfloor airflow with IT equipment needs.

If you recognize the importance of energy consumption, the search is over.  At EEC, we provide solutions that are economically viable and environmentally effective for your data center utilizing the appropriate technology and services for ensuring a ‘greener’ and more cost-effective future.
