power distribution solutions for the ProLiant DL580 G2 server introduction This white paper provides power information for system configurations using the ProLiant DL580 Generation 2 (G2) server. This information is intended for field systems engineers, IT managers, installation technicians, or any personnel tasked with the installation and maintenance of the ProLiant DL580 G2 server.
power distribution solutions for the ProLiant DL580 G2 server term description ground leakage Residual current flow through the grounding conductor, which is current always undesirable. With data processing occurring at everincreasing speeds, most IT equipment includes capacitors in the power circuits to filter radio frequency (RF) signals to ground. While effective at filtering RF, these components tend to allow a small amount of AC current to pass to the ground.
power distribution solutions for the ProLiant DL580 G2 server ProLiant DL580 G2 server power requirements In the standard single-processor configuration, the ProLiant DL580 G2 server includes one 800-watt power supply that can operate off high or low AC power. Multi--processor configurations are shipped with two, fully redundant power supplies. Single power supply units can be upgraded to a dual-power supply configuration with a redundant power supply option kit.
power distribution solutions for the ProLiant DL580 G2 server power distribution solutions HP recommends using power distribution units (PDUs) in installations where a number of server units can place serious loading demands on the AC power bus. HP offers PDUs that provide safety and reliability to multi-server installations. The units described in this white paper offer 0U/1U mounting options and feature circuitbreaker protection of equipment in groups.

power distribution solutions for the ProLiant DL580 G2 server high voltage (208VAC) 6-chassis power configuration Figure 5 shows a configuration where high voltage (208 VAC) is distributed to six server chassis in a rack that receives primary and secondary power busses. A modular PDU that consists of a control core and two extension bars is connected to each power bus. Each control core can handle a maximum of 24 amps. In this case, each core could be called on to provide about 22.
power distribution solutions for the ProLiant DL580 G2 server high voltage (230 VAC) 9-chassis power configuration Figure 6 shows a configuration where high voltage (230 VAC) is distributed to nine server chassis in a rack that receives primary and secondary power busses. Each power bus is handled by a modular PDU that consists of a control core and three extension bars. Each control core can handle a maximum of 32 amps. In this case, each core could be called on to provide about 30.
power distribution solutions for the ProLiant DL580 G2 server low voltage (120 VAC) 3-chassis power configuration w/modular PDUs The following figure shows a configuration of three server units operating off primary and secondary low voltage busses through two modular PDUs rated at 24 amps each. With a combined server load of 22.2 amps, approximately 1.8 amps are left for peripheral devices.
power distribution solutions for the ProLiant DL580 G2 server low voltage (120 VAC) 3-chassis power configuration w/single input PDUs The following figure shows a configuration of three server units operating off primary and secondary low voltage busses through two single input PDUs rated at 24 amps each. With a combined server load of 22.2 amps, approximately 1.8 amps are left for peripheral devices that in this particular case could be plugged into each PDU’s 9 remaining NEMA 5-15R outlets.
power distribution solutions for the ProLiant DL580 G2 server online calculators HP provides online calculator utilities that simplify the process of determining power requirements and offer convenient “what if” calculations. These utilities, available online at no charge, offer several advantages over “scratch pad” methods using nameplate specifications: • Calculations are based on formulas using actual measurements of equipment running a Windows meat grinder utility.
power distribution solutions for the ProLiant DL580 G2 server The Power Calculator utility is convenient for small server system planning or for making minor additions to existing installations. For a more thorough analysis of a complete installation, the Rack/Site Preparation utility is recommended. Rack/Site Preparation utility The Rack/Site Preparation utility will calculate all power, vertical rack space, and airflow requirements for a complete server installation.
power distribution solutions for the ProLiant DL580 G2 server To use the Rack/Site Preparation utility: 1. Select either the “Express” or “Advanced” mode of calculation. Express calculation uses pre-set values for components and can be used for producing a quick estimate of system requirements. Advanced calculation requires user to configure individual components and is recommended for final installation planning. If “Express” mode is selected, then proceed to step 5. 2.
