Power consumption The type (low-line or high-line) and amount of power (in VA) required by the equipment in a rack largely determines the type of PDU(s) to use. HP provides online power calculators for making accurate power consumption estimates for most ProLiant servers. Each calculator (Figure 2) allows the IT infrastructure designer to predetermine the power requirements for a server chassis according to configuration parameters entered into the calculator. With accurate estimates of power requirements for individual server chassis, infrastructure designers can easily calculate power consumption for a fully-configured rack.

HP Online Power Calculator (partial screen) The HP Online Power Calculator also provides estimates of current draw, watts consumed, and inrush current. These are factors to consider when choosing PDUs. The HP Online Power Calculator also provides a BTUs/hr calculation for planning the cooling requirements of an installation. 5
