cooling systems  Modes of Data Center Cooling Systems In certain climates, some cooling systems can save over 70% in annual cooling energy costs by operating in economizer mode, corresponding to over 15% reduction in annualized Power Usage Effectiveness (PUE). However, there are at least 17 different types of economizer modes with imprecise industry definitions, making it difficult to compare, select, or specify them. This paper provides terminology and definitions for the various types of economizer modes and compares Read More

Making Large UPS Systems More Efficient
As energy resources become scarcer and more expensive, electrical efficiency is a more important performance factor in the specification and selection of large

cooling systems  400 watts for the cooling system to remove it, an additional $8,376 vs. $22,651 per year is required2. In this example, a typical data center lifespan of 10 years, results in a total cost of UPS system losses of $293,165 vs. $793,021 as shown in Table 1. So, how is it that the electrical losses between two seemingly identical UPS systems can differ by almost a factor of three? The answer lies in the efficiency curves of both UPS systems and how they are sized against the load. An improvement of 5 Read More

However, monitoring of branch circuits at the rack and temperature at the rack is a relatively new concept in NCPI management. Monitoring individual branch circuits contributes to availability by enabling an administrator to receive a notification before a circuit is overloaded. Studies have shown that a significant cause of Read More
The Advantages of Row- and Rack-oriented Cooling Architectures for Data Centers
The traditional room-oriented approach to data center cooling has limitations in next-generation data centers. Next-generation data centers must adapt to

Row-oriented and rack-oriented cooling architectures have been developed to address these problems. This paper contrasts room, row, and rack architectures and shows why row-oriented cooling will emerge as the preferred solution for most next generation data centers. Introduction All of the electrical power delivered to the IT loads in a data center ends up as waste heat that must be removed to prevent Read More
An Improved Architecture for High-efficiency, High-density Data Centers
Globally, data center power and cooling infrastructure wastes more than 60 million megawatt-hours per year that do not contribute usefully to powering IT

cooling systems  data center power and cooling systems (see box). Various proposals to address the waste of power in data centers by improving the performance of power and cooling systems have been described in the literature. Some of these, such as direct water pipe connections to IT devices and DC power distribution, promise incremental improvements to system efficiency but are impractical today. This paper introduces an improved data center architecture ' available and practical today ' that reduces the energy Read More

cooling systems  Systems Development: Three Proven Practices for Speed and Agility Many manufacturers are incorporating embedded systems into their products to meet the growing demand. While this approach offers exciting opportunities for innovation, it also adds a level of complexity to products that have zero tolerance for bugs and must beat the competition to market. But companies that successfully address these challenges are seeing higher profitability—in spite of the current economy. Find out why. Read More
