DCA CONSULTING - Quality Consulting Services to Data Center. DCA Consulting uses a careful, pragmatic approach to investigate, gather data, analyze and resolve the most complex power quality, contamination and cooling problems by using state-of-the-art testing and monitoring equipment. DCA consulting not only offers 25 years experience but they offer a professional and proven scientific approach to solving problems in today’s data centers. Everyday, our specially trained technicians clean a myriad of cleanrooms, computers rooms, laboratories, telecom facilities, and video sites : Data center cleaning. KoldWorks is a suite of specialized engineering and educational services designed by Upsite Technologies® to enhance data center performance without additional capital investment.DCA Consulting focuses on improving the productivity and reliability of electronic equipment in the data center environment through consulting services. DCA Consulting offers power quality expertise for the most complex power problems. DCA offers expertise for all aspects of power quality for the data center environment including EMF, high frequency and RF interference, and those hard to diagnose grounding issues that may be causing intermittent interruptions in the data center operation or network performance. The PUE or Power usage effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1. PUE was created by members of the Green Grid, an industry group focused on data center energy efficiency. For your offices, DCA Consulting may not be your first choice to investigate the IAQ however for your data center, DCA Consulting should be your only choice. No one knows more about data centers than we do. We know where to look and what to look for.

	POWER QUALITY
	High Frequency Interference
	RFI and HFI involve the presence of unwanted, interfering frequency signals that disrupt normal system operations. These radiated or coupled frequencies are typically above 10 KHz and are from various wireless devices such as radios, walkie talkies, cell phones, radar transmitting stations and other wireless technologies. Coupled frequencies can be from microwave ovens, florescent lights, noisy switches or motors and even lightning storms can generate HF interference and cause intermittent equipment performance and failure. LAN networks, microprocessors and especially wireless LAN networks tend to be specifically susceptible to performance degradation from RF and HF interference. Solving the interference may be as simple as adding ferrite cores to cables or as complex as building a Faraday cage around the equipment or room to protect and isolate from unwanted radiated frequencies. Grounding is always an important component in resolving interference issues. In data centers, signal reference grounding may be the solution to unwanted high frequency noise that is causing intermittent failures or lock-ups. Understanding the source of the interference is usually crucial to resolving the offending problem. Identification of RF interference takes very specialized equipment to capture and analyze the frequency spectrum of the interference. DCA Consulting has the expertise to audit the site, install the necessary equipment, identify the frequency and provide a solution to resolve offending radiation.
