efficient solution for three-phase power distribution. Introduction An enterprise data facility contains a large amount of IT equipment with substantial power requirements. Energy usage has increased to the point that it is second only to labor in operating costs for some large facilities.

centers to change and grow easily. For example, adding one or two racks in today's conductors must be large to meet high amperage requirements. Three-phase power uses four discrete conductors ( the three hot conductors results in smoother current flow and allows the use of smallergauge conductors to - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 5
server systems often use power supplies that can operate with either low-line or highline power, but require high-line power to operate at maximum rated performance and peak efficiency. Frequency tolerated by most power how long the UPS can provide the rated power in the online (battery) mode. 5 - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 6

switched to DCOD operation to process the AC input and provide a three-phase AC output that meets load requirements. When AC input power is absent, the system goes into battery mode. Figure 6.

and control of the UPS from a remote workstation. Each UPS includes an automatic maintenance bypass switch that allows replacing the hot-pluggable batteries and electronics module without shutting down the system. The UPS can be configured with one of several input/output receptacle types to match - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 9
power distribution units (PDUs) to be installed in pairs to achieve a balance of equipment loading. With three-phase distribution, each equipment rack requires only one cable providing three hot wires and one neutral conductor. Load balancing is possible with one three-phase PDU, which simplifies - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 10
by a 400-amp, three-pole (3P) input circuit breaker. The distribution panels support 1P, 2P, and 3P breakers of a wide range of amperage ratings to allow IP address. HP offers a selection of power distribution cables (Figure 11) for connecting the PDR to IT equipment rack PDUs. The power - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 11

A 60-kW UPS rack can support: • 10 low-density racks at 6 kilowatts utilities for calculating the power requirements for HP server products - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 12
-kW ITE racks powered from a UPS rack of parallel HP RP12000/3 UPSs to provide 60 kilowatts of power distributed through the HP PDR. In this example, the HP Modular Cooling System (MCS) is used to provide chilled-water, forced-air cooling for the IT equipment. The UPSs and PDR use conventional - Compaq R6000 | Increasing energy efficiency with modular HP three-phase power di - Page 13
of cooling up to 35 kW of IT equipment. Two or more HP MCS racks with a maximum ITE load will require additional UPS support.
