67 CDWG.com | 800.808.4239 itself to confirm that it will be available in case of an emergency and signal IT managers when a battery is going bad or when the UPS is nearing its overload threshold. Intelligent PDUs offer a built-in network jack and individually controllable outlets, which let IT managers remotely reboot a network switch, for example, if a problem occurs with equipment in a wiring closet. But true digital intelligence requires interoperable components. "If you get a rack from one vendor, a UPS from a different vendor and PDUs from a third vendor, none of this equipment may be able to talk together," Mutabdzija says. "Look for solutions that all speak the same language. It's even better when UPSs and PDUs speak the same language as your IT equipment. is will give you a holistic pane of glass to proactively monitor power usage, temperature and humidity, as well as the status of your IT equipment, whether the facilities are in the same building or across the city, country or globe." For example, Tripp Lite offers two models that are 16.8 inches deep or 13 percent smaller than conventional units. Capacity Capabilities How much UPS capacity is enough? In some cases, organizations need enough battery life to support data backups and equipment shutdowns that take 30 to 60 minutes to complete. "It's important to accurately calculate exactly how much runtime you will need during an outage so you can determine the right sized UPSs," Beyhaut says. ese estimates also play a pivotal role in determining the right PDUs to install in these areas, Beyhaut adds. To accommodate tight physical constraints, many IT managers choose zero-U, vertical PDU designs that provide outlets to the full height of a rack. Even models with the largest housings may measure only about 2.5 inches square, a dimension appropriate for small areas. In addition, the overall design doesn't use up any rack space. e best UPSs and PDUs for small spaces provide critical information for administrators of distributed IT environments. " ey're your eyes and ears to what's going on in that particular closet," Feldhaus says. For example, a "smart" UPS can test cabling and wires all over the place, which can impair heat dissipation. e conditions inside the rooms often go unmonitored, so people don't know about problems until something goes wrong with the IT equipment." To maintain reliable power supplies and sustain operations during brownouts or long-term disruptions, IT managers need UPSs that not only protect valuable equipment but also accommodate small spaces. UPSs designed for much higher capacity tend to be "big, bulky and heavy, built into a form factor more fitting for a conventional data center," says Rich Feldhaus, product manager at Tripp Lite. at's not the case when IT managers use compact wall-mount or open-frame racks to optimize space in closets and small rooms, rather than the conventional full-size racks common in traditional data centers. e smaller depth dimensions of the thinner two-post racks present problems when organizations use them to hold full-size UPSs optimized for four-post racks. "People sometimes call standard UPSs 'kneecap busters' when they're in a wiring closet because they extend from the rack at kneecap level," Feldhaus says. As a result, Tripp Lite and other UPS vendors now offer compact rack-mount UPSs with reduced depths. Smaller doesn't mean less important. In fact, it could mean the opposite. Organizations need to pay more attention to these sometimes-forgotten spaces because they're often the main connections to the organization's users and to its data in the cloud. --- Srdan Mutabdzija, Solutions Manager at APC by Schneider Electric MANAGE DATA CENTER POWER AND COOLING Conserving energy while maintaining an efficient and low-cost data center is becoming increasingly difficult in today's environmental climate.
