DATA CENTERS Data Center iStock/4X-image Power THE SPECIFIC POWER REQUIREMENTS OF DATA CENTERS AND THE IMPORTANCE OF REDUNDANCY BY DAVID C. RICHARDSON Manning the Barricades yle Ellenberger of Power Systems & Con-trols has seen big changes in the data center industry since the earliest few data centers were launched in the United States. “The ﬁ rst data centers were crazy—they had soldiers guarding them and barbed wire. No, you can’t roll up in a tank and steal data,” he says. But things have changed a lot since then. Just about every-K one recognizes that the most persistent threats to data are inﬁ nitely more likely to weasel their way down a thin strand of wire than rumble through the gates in a frontal assault. For Ellenberger, avoiding power interruptions represents one of the main lines of defense for critical facilities. “When people think about UPS systems they think about data centers, and that makes sense,” he says. “UPS is about a $10 billion industry, and data centers, data processing, and data storage are probably responsible for about $9 billion of that.” 28 www.
