Containment Helps Data Centers Go Green

A Subzero White Paper by Gordon Johnson

High levels of energy consumption cause a push for greener and more environmentally friendly data centers

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

New White Paper discusses the Essentials of Data Center Containment

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.

Key Features of Polar PDUs

Learn about the many useful features of Subzero Engineering’s Polar PDUs

Secure Link

Secure Link consolidation technology reduces costs and decreases installation time by allowing you to link up to 32 PDUs under a single IP address using standard Ethernet cables. Enjoy features such as outlet grouping, data logging, threshold alarms, and PDU cloning. Adding a second IP address provides failover capability, which allows functioning PDUs to continue communicating if a PDU in the array loses connectivity.

High Ambient Temperature Rating

Designed to withstand the heat loads of any vertical exhaust duct or hot aisle containment environment and allows full implementation of the newest ASHRAE recommendations. Perfect for installation in high-density application cabinets, all Polar PDUs are optimized for use in ambient air temperatures up to 149°F (65°C) at the input power rating (kW), ensuring that they will perform reliably in any hot aisle environment. In addition, Polar PDUs feature a low-profile design that does not block airflow.

Locking Outlets

Polar PDUs with IEC outlets come standard with locking outlets. This feature fastens straight equipment power cords to the PDU without the need for proprietary accessories, allowing you to save on additional accessory costs.

UL Listings/Circuit Protection

All PDUs are UL® 60950 listed and CE marked. They utilize100% rated, slim-profile hydraulic magnetic breakers to minimize nuisance tripping due to temperature variations and minor overloads.

NYC Raises the Roof

New York City Approves the Polar Cap 2 Retractable Roof

In a Buildings Bulletin dated October 19, 2016, NYC Buildings Department establishes acceptance criteria for retractable-type horizontal cold aisle containment systems installed in information technology equipment areas.

The installation of a retractable-type horizontal cold aisle containment system installed in information technology equipment areas (horizontal cold aisle containment system) is used to minimize the consumption of energy by providing an overhead thermal containment barrier used to create a cold aisle. However, the overhead containment barrier may obstruct the performance of code-required fire suppression systems (BC Chapter 9). This bulletin establishes acceptance criteria for horizontal cold aisle containment compliance with the NYC Construction Codes.

The Subzero Polar Cap 2 is a fully electric roof system that retracts into a metal housing when the fire suppression system is alarmed. Having a pre-action system that reacts to a smoke detector will ensure that the containment roof is fully retracted long before the fire suppression system is discharged. Additionally, the roof material meets the stringent flame and smoke requirements of ASTM E-84 Class A Rating. The Polar Cap 2 can also be manually opened and closed when maintenance is required above the containment space.
