Server cabinets with isolated return air paths provide a complete barrier in the data center between supply air and return air and create a healthy living environment for very high densities of computer hardware. This isolation system eliminates waste, creates higher return temperatures for better cooling unit efficiency, and higher supply air temperatures for better chiller plant efficiency and more economization hours. Such isolation enables a path to higher densities, lower costs and more easily achieved fault-tolerant concurrently maintainable systems.

Conducted with one of Digital Trust's major customers, this presentation will provide an in-depth look at the issues surrounding the measurement of energy efficiency. Included in this session are real world examples of the multiple factors that must be considered in evaluating measurement data. Also included is a demonstration of the practical application of measurement data aids users in ensuring that their datacenter energy usage is as efficient as possible.

This presentation will introduce the Rittal Cold Aisle Containment (CAC) system - components designed to enclose the cold aisles in IT spaces, providing maximum delivery of cold air to server intakes. Procedures and monitored parameters of CAC system testing will be presented along with performance data summarizing test results. A variety of parameters and results will be provided, all with the goal of detailing the positive effects of deploying a CAC system for medium density (10-20 KW/enclosure) applications.

With a technical infrastructure spanning offices in nearly every major city in the world, SAS puts tremendous demands on its own IT systems - facing the familiar challenge of "doing more with less" every step of the way. Hear how the SAS IT organization has unearthed ongoing cost take outs, even beyond virtualization and optimization.

First, attendees will learn how IT cabinet airflow circulation patterns create high intake temperatures based on CFD analysis and case examples. Second, the impacts on capital and operating expense management will be discussed. Third, attendees will learn the relationship of cabinet airflow to overall room efficiency and the next steps to improve overall cooling and energy efficiency.

Recovering data center capacity and redundancy, cutting utility bills, and "greening" all begin with energy measurements - electricity, natural gas, steam, central plant chilled water, free-cooling, etc. The very act of measurement will identify obvious improvements - but what next? How good is "good enough?" Getting comparable measurements and then benchmarking them against best-in-class peers is a lot harder than it appears. How do you compare your site against peers with different business reliability needs, different equipment configurations, or located in different climates? How do you split out the data center from a larger building? Which performance factors do you control, and which are out of your hands? Where should you look for waste, and what are the financial consequences of inaction? Join Uptime Institute's facility benchmarking experts (benchmarking energy efficiency since 2001) to get answers to these questions, as well as other insights into facility measurement "gotchas" that can frustrate even experienced energy managers.

By taking a different approach to data center cooling system design, and harnessing proven technology, data center cooling systems can achieve Ultra-Efficient levels that would see current energy use reduced by up to 60 percent, but just as importantly offer overall superior performance and reliability.

There are perpetrators who are now using devices to emit high frequency pulses which disable data center electronic systems and cause data disruption, potentially violating regulatory requirements. EMPrimus designs and delivers a full-range of vetted and proprietary protection solutions against this electromagnetic threat.

RTKL Associates Inc. will discuss infrastructure voltages to maximize efficiency at the rack level. The presentation will provide a high level analysis of utilizing 600/480/400V system to critical loads, with a discussion of the pros and cons of each system. We will present a holistic approach from input to UPS to distribution rack, with most typical reliability configurations. We will discuss an investigation of part load efficiencies of major components and the impact of system efficiencies. Lastly, we will address the means of maximizing the efficiencies to provide the user with the best approach to their data center facility.

This presentation explores device power measurements within the data center cabinet using a cabinet power distribution unit. These measurements can be used to help calculate PUE and DCiE efficiency metrics, allocate cooling resources, identify comatose servers, and for capacity planning. It also looks at kW-h power information that can be used for billing specific departments within an enterprise data center or by co-location facilities for billing based on actual power usage.

The technical presentation on energy-efficient strategies and technologies for cooling the data center will cover the topics of traditional data center cooling methods vs. innovative new developments that are significantly reducing data center operating costs. Calculations and examples will be provided for illustrative and discussion purposes.

Efficient management of Information Communications Technology (ICT) and facility components goes beyond typical monitoring approaches. Enabling intelligence across ICT and facility apparatus enables the application of 27 useful models - models that can produce actionable information and trending analysis. This output can include everything from proactive maintenance and efficiency analysis reporting, to specific costing data - such as the amount of energy consumed or pollution produced down to the virtual operating system instance, server, chiller, building, floor, or rack.

The primary IT data center at Lawrence Berkeley National Labs faced the possibility of running out of capacity between 2010 and 2012. In 2007, they deployed a wireless monitoring solution to launch their data center efficiency effort. Learn about the tools and methodology they employed to fine-tune their data center and maximize efficiency.

The Lawrence Berkeley National Laboratory report "DC Power for Improved Data Center Efficiency" (March 2008) highlighted the potential increase in datacenter efficiency using high voltage (~380V) DC power. One area noted for further discussion was the conversion and distribution of power efficiently from this high voltage to the actual processor and memory loads in the data center. This presentation compares a traditional power architecture with a new ‘Sine Amplitude Converter' topology and architecture to drive sub-1V loads.

This presentation provides a brief history of the raised access floor industry and explores the benefits of reconditioning existing access floor materials versus purchasing new material. We examine the economic, environmental and social benefits of reuse versus purchasing new material. In addition, we quantify the global savings derived when the rehab process is delivered onsite and in conjunction with subfloor cable mining and addressing conditioned air loss.
