Electrical Efficiency Modeling for Data Centers

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).

Understanding ERP Deployment Choices

Enterprise resource planning (ERP) systems were once deployed as monolithic systems running in local data centers. Today, there are a multitude of ERP deployment strategies: single-system, cloud-based, operational, peer, hybrid, and multilevel approaches. Advances in ERP system design, the advent of cloud computing, and the ongoing evolution of business are among the key factors driving this proliferation of choices. Read More

Counting the Cost of Network Efficiency

It is hard to quantify the costs of poor network or application management, but they include lost productivity due to time spent fixing problems and increased capital and operating expenses. But when creating IT budgets, organizations need to consider the impact of investment in network and application management on overall revenues. IT efficiency should be a priority item for any corporate agenda, and executives need to understand that the network is not only a core part of what their organization... 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 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. Read More

Electrical Efficiency Measurement for Data Centers

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. Read More

Energy-efficient Cooling for Data Centers: A Close-coupled Row Solution

Perimeter computer-room air handlers and central air-handling units have been used to cool data centers since the launch of the mainframe. But as rack power grew, air delivery and heat removal challenges appeared. Row-based designs address issues of proper heat removal and cold air supply—and bring energy-efficiency advantages.
