Best Practices for Power Equipment Startup
Date: June 9, 2009
In order for the electrical power distribution systems within data
centers and related facilities to operate properly as designed and
intended, it is extremely important that care be given to the
commissioning and startup of the electrical equipment via effective and
reliable methods. This paper describes the need for a systematized
program for new power equipment startup and the best practices and
pitfalls that exist with regards to power equipment startup. This paper
will also provide an overview of important items and issues that should
be focused upon as part of reliable power equipment start up procedures
and processes.

Managing Extreme Heat: Cooling Strategies For High-Density Systems
Date: April 20, 2009
As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. As these new systems are installed alongside previous generation systems, they create hot zones within the data center that cannot be effectively managed using traditional approaches to cooling. New strategies and technologies must be implemented to provide the cooling high-density systems require for reliable operation.

Technical Paper: Specifying “Quality Sound”
Date: July 1, 2007
There’s more to “quality sound” than low sound levels. This paper sets out to clarify the most commonly used descriptors of sound, including sound power, sound pressure, octave bands, noise criteria (NC), room criteria (RC) and the A-weighting network (dBA). It also examines ways of specifying desired acoustical comfort and emphasizes the importance of specifying acoustical performance based on an analysis that converts sound power to sound pressure.

Improved Chilled Water Piping Distribution Methodology for Data Centers
Date: May 15, 2007
Chilled water remains a popular cooling medium for data centers; however, leaks in the piping systems are a threat to system availability. High density computing creates the need to bring chilled water closer than ever before to the IT equipment, prompting the need for new high reliability piping methods. This paper discusses new piping approaches, which can dramatically reduce the risk of leakage and facilitate high-density deployment. Alternative piping approaches and the advantages over traditional piping systems are described.
