FEATURE 2 AVOIDING COMMON DATA CENTER DESIGN MISTAKES by Jeffrey R Clark, Ph.D. Building a data center can cost millions of dollars, or much more, in capital expenses. Companies therefore have a tremendous incentive to ensure that the process avoids overrunning the budget and is completed on schedule—two feats that are challenging enough by themselves. But even once the facility is operational, mistakes made during the design phase can reduce efficiency or cause downtime, leading to greater costs through lost business, decreased productivity and repair expenses. FACILITY CORNER 6 POWER SYSTEM EQUIPMENT MAINTENANCE AND LONG-TERM SERVICING REQUIREMENTS FOR DATA CENTERS by Ken Agent, P.E. No engineered system can run indefinitely without the need for maintenance, and the electric power equipment found in Data Centers is no exception to this rule. This article will address maintenance considerations in the initial design of a data center and how they enhance long-term reliability. And why equipment servicing and maintenance are crucial to the long-term operation of a data center power system, and the typical servicing activities for different types of equipment. 9 MONITORING AND MODERNIZATION: PREPARING A DATA CENTER FOR THE FUTURE by John Collins When making the investment in a data center, most businesses hope to receive more than two decades of reliable operations. However, some of the vital backbone components that the data center relies on – its mechanical, electrical and plumbing (MEP) systems – are not designed to last that long. 12 DATA CENTER COMMISSIONING AND THE MYTH OF THE PHASED BUILD by Chris Crosby and Kfir Godrich Data center commissioning is one of those areas that everyone has heard about and is familiar with. Unfortunately, familiarity doesn't equate to understanding as evidenced by the fact that so many folks still entrust their company's mission critical applications to data centers that have not fully completed the process. An incomplete commissioning turns on the engines and kicks a couple of tires, but it doesn't take the plane up into the air to make sure that it can actually fly. DC MANAGEMENT 15 MANAGING CRITICAL WORK IN A LIVE DATA CENTER by Jeffrey R Clark, PhD Downtime in your data center can be costly. But failing to adequately maintain your facility means you're in for unexpected downtime—which can be much worse than planned downtime. If your data center receives much lighter traffic at certain times of day or certain times of the year, scheduling a service break during those off hours is one possibility. For instance, if product sales are virtually nonexistent during late-night and earlymorning hours, those times are a good opportunity to put operations on hold while you perform needed maintenance or other critical work.

The most sophisticated tools available today are mainly software packages that require some level of 3D or solid modeling. The use of these is often not well understood, and at times are even used interchangeably or incorrectly. 20 SIMPLIFIED DATA CENTER ENERGY MODELING: HOURLY WEATHER ANALYSIS COUPLED WITH LOW-COST CFD MODELING by Dana Etherington, CEM, LEED AP BD+C The analysis methodology outlined herein is intended to guide early phase decision making. This allows us to review high level energy saving strategies, seek rebates through local utility programs and identify 'white space' design issues early on. ITOPS 28 IT'S A WHOLE NEW (DATA CENTER) WORLD: MANAGE IT WISELY by Sev Onyshkevych In the dynamic world of servers, storage and networks, management is no easy proposition. That's because data centers aren't just big – they're huge. The massive amount of processing power needed to drive business operations means companies are always adding new devices and increasing energy use. 32 CALENDAR 32 VENDOR INDEX AN EDM2R ENTERPRISES, INC.
