BENEFITS OF INTELLIGENT RACK PDUs Intelligent rack PDUs resolve the main data center challenges covered earlier. Table 1 illustrates the key features of the various intelligent rack PDU types. The benefits for selecting the right intelligent rack PDU for the customer's application are outlined in Table 2. Energy cost can be reduced by identifying inefficient equipment, malfunctioning equipment, or underutilized equipment. Replacing old or comatose equipment with more energy efficient equip- ment contributes to energy cost savings. Cooling overprovisioning contributes to increased energy costs. Cooling makes up approx- imately 40 percent of the data center energy cost. 9 One way to reduce this cost is to raise the set temperature in the data center. Intelligent rack PDUs with measuring and mon- itoring functionality enable data center managers to safely raise temperature and monitor the impact on data center equipment and overall perfor- mance. For every degree rise in set temperature, there is approximately a 4 percent energy cost savings. 10 FIGURE 2: How intelligent rack PDUs answer the call. 8 TABLE 1: Key features of the various intelligent rack PDU types.
