Abstract: Conventional models for estimating the
electrical efficiency of data centers are grossly inaccurate for real-world installations.
Electrical loss estimates are typically made by summing inefficiencies of
electrical devices, such as power and cooling equipment. Discover a more accurate efficiency model that can help you identify and quantify waste in power and cooling equipment, and reduce total cost of ownership (TCO).

Abstract: Data center electrical efficiency is rarely planned or managed. The unfortunate result is that most data centers waste substantial amounts of electricity. Today, it is both possible and prudent to plan and measure data center efficiency. In addition to reducing electrical consumption, efficiency improvements can bring higher IT power densities. Learn how to describe, measure, and evaluate data center efficiency.
Abstract: When it comes to two-dimensional (2D) symbologies, less is more. While 2D bar code symbols may be less costly to print, they are considerably more expensive to read, because of the complexity of developing decode algorithms. However, with the integration of public domain 2D symbologies into a range of application standards, solutions employing these codes are beginning to reach their full potential.
Abstract: Despite intense price competition for its volume products, the electrical products industry remains healthy and dynamic. World-class companies are succeeding by marketing innovative products, scaling up and outsourcing production, expanding into new geographic areas, implementing more efficient business systems, and focusing on ever-closer relationships with suppliers, partners, and customers. This white paper explores the issues of manufacturers, wholesalers, and distributors and the current state and future of the industry. Industry specific technological are also discussed.
Abstract: Electro-mechanical design continues to gain importance, as the majority of today’s products have both electrical and mechanical components and systems. Designing and stimulating these products collaboratively across both domains is essential to producing high quality products. Learn how implementing an electro-computer-aided design (ECAD) and mechanical computer-aided design (MCAD) strategy—now—can help you later.
Abstract: Electricity costs are an increasing portion of the total cost of ownership (TCO) for data centers. But you can dramatically reduce the electrical consumption of typical data centers through appropriate design of both the network-critical physical infrastructure and IT architecture. Discover how to quantify electricity savings and learn about methods that can greatly reduce your data center electrical power consumption.
Abstract: A study from Iowa State University’s Department of Electrical and Computer Engineering suggests that the format and organization of a proposal can significantly affect a vendor’s chance of winning a contract. And we thought those university professors didn’t know much about the real world!
Abstract: The European Union’s WEEE Directive requires electronics manufacturers of member states to manage and pay for electrical and electronics waste recycling. Yet some prospective business service providers are waiting for the legislation and market to mature before offering their solutions.
Abstract: As energy resources become scarcer and more expensive, electrical efficiency is a more important performance factor in the specification and selection of large uninterruptible power supply (UPS) systems. There are three subtle but crucial factors that can affect the cost of operating a UPS system. Sadly, these factors are often unrecognized. Find out what they are, as well as common errors in evaluating UPS efficiency.
Abstract: Blade servers have a major advantage over traditional ones—improving processing ability while using less power per server. But, with their smaller footprint, blades can be much more densely packed, resulting in racks that use up to 20 times the electrical power and generate up to 20 times the heat. This can stress power and cooling system capability. Learn how to create a power and cooling strategy with these guidelines.
Abstract: Conventional methods for specifying data center density don’t provide the guidance to assure predictable power and cooling performance for the latest IT equipment. Discover an improved method that can help assure compatibility with anticipated high-density loads, provide unambiguous instruction for design and installation of power and cooling equipment, prevent oversizing, and maximize electrical efficiency.
Abstract: When looking for a data center rack solution, you should be familiar with the alternatives for providing electrical power to high density racks in data centers and network rooms. Learn why your rack power system should adapt to changing requirements, and get guidelines for power rack systems that can reliably deliver power to high-density loads, while adapting to the changing needs of your data centers and networks.
Abstract: North American server installations are uniquely inefficient because of multiple circuits, use of floor space and weight, and more. A new approach to power distribution for high-density server installations saves floor space, simplifies power cabling, saves capital cost, reduces weight, and increases electrical efficiency. Learn more about how this distribution architecture can provide you with numerous benefits.
Abstract: New power and cooling technology allows for a simple and rapid deployment of self-contained high-density zones within an existing or new low-density data center. The independence of these high-density zones allows for reliable high-density equipment operation without a negative impact on existing power and cooling infrastructure—and with more electrical efficiency than conventional designs. Learn more now.
Abstract: Many of the mysteries of equipment failure, downtime, software, and data corruption are the result of a problematic power supply. Compounding the problem is that there is no standardized way to describe power problems. Learn more about common power disturbances, what can cause them, and how to safeguard your critical equipment—all described in Institute of Electrical and Electronics Engineers (IEEE) standard terms.
Abstract: Globally, data center power and cooling infrastructure wastes more than 60 million megawatt-hours per year that do not contribute usefully to powering IT equipment. This is an enormous financial burden on industry, and is a significant public policy environmental issue. Find out about the principles of a new data center architecture that can be implemented today to dramatically improve the electrical efficiency of your data center.
Abstract: The power grid is pushed to its physical limits with our growing demands for cheap electricity. To keep up, we need a “smart” electrical grid prepared for real-time information and enabling fast response. A new power delivery system can manage supply and demand while allowing consumers to manage their energy usage online. Read more about the benefits for utility companies, consumers, the economy, and the environment.
Abstract: The crucial interoperability of wireless network devices built around the 802.11 standard is threatened by the advent of faster technologies. The Institute of Electrical and Electronics Engineers (IEEE) is trying to cope by developing the 802.11n standard—but it’s still in draft form. Meanwhile, how can manufacturers cope with the confusion surrounding the future of 802.11? Get an outline of the situation.
Abstract: With 3-D computer-aided design (CAD) models taking on a broader and more significant role in the development of new products, CAD files must flow smoothly into downstream applications. Sometimes, however, errors do occur. An off-the-shelf software tool can detect problems in the design stage so they aren’t discovered at a crucial moment in the manufacturing process, when it may be costly—or even too late—to correct them.
