Containment Helps Data Centers Go Green

Containment Helps Data Centers Go Green

A Subzero White Paper by Gordon Johnson

Data centers are a huge part of today’s economy, with both businesses and people connected 24/7. However, along with this usage comes a huge drain on our energy resources. Recent studies show that energy consumed by data centers in the U.S. alone has doubled over the last five years. With the growth of cloud computing and High Performance Computing (HPC) and the energy required to operate them, this trend is not disappearing anytime soon. Fortunately, many realize that this high level of energy consumption cannot continue indefinitely, and the push for greener and more environmentally friendly data centers is being taken seriously.

What can data center and facility managers do to stop this runaway train? While there are several options to get greener and thus lower the overall cost to operate a data center, this paper specifically focuses on containment. Why? Containment is the fastest, easiest, and most cost effective strategy to going green while simultaneously lowering operating costs without adding additional CapEx to the data center. In addition, containment makes other options either possible or economically feasible. This paper will show why this is true, while discussing the following topics:

  • Why Being Green Matters
  • Containment is the Smallest Action with the Greatest Outcome
  • Containment = High Efficiency = Green Data Center
  • Containment’s Role in HPC
  • Efficiency: Full Containment Versus Partial Containment
  • Efficiency: Cold Aisle Containment Versus Hot Aisle Containment
  • CFD Predicts Energy Savings & Environmental Footprint

Data Center Containment 101

A Subzero White Paper by Gordon Johnson

Regardless of if we’re entering a data center for the first time or have been doing so for
years, most data centers have something in common. As you walk through rows of racks,
you’ll alternate between cold and hot aisles. You’ll hear expressions like “CRACs”, “PUE”,
“White Space”, “Cold Aisle Containment”, “Hot Aisle Containment”, and many more. The
purpose of this White Paper is to assist those new to the data center and those assigned
with making key decisions to get the most out of existing “legacy” and newly designed data
centers.

Since energy efficiency and data reliability are key goals for anyone managing or associated
with data centers, how can we achieve both in the shortest amount of time while getting
the quickest ROI (Return of Investment)? When is it more appropriate to use one type of
containment instead of another type? Which saves more money? This paper will answer
these and other questions.

Containment’s Role in Energy Efficiency and Rapid ROI

A Subzero White Paper by Gordon Johnson

Everyone today is interested in saving money, and that’s especially true in data centers. Between the cost of electricity and the increasing trend for higher power densities per rack (20 kW and above is no longer uncommon), the desire to be energy efficient and to reduce cost on the annual utility bill is a major concern throughout the data center industry.

So what can be done to save energy and thus save money? How can we lower our PUE (Power Usage Effectiveness) while increasing energy efficiency without sacrificing reliability? What technology will deliver a rapid ROI, often between 6 and 18 months? Containment is the answer.

How does containment provide energy savings for data centers? Is there a way to estimate the annual savings and PUE for containment installations? This White Paper will provide an answer to these questions.
