HP ProLiant DL360 G3 Server High-Density Deployment Preliminary 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 figures: • Calculations are based on formulas using actual measurements of equipment running various exercise utilities. • Calculations are based on active components exercised at 100% duty cycle, generally allowing headroom for typical installations. • Air volume calculations based on measurements taken in equipment operating with an airflow chamber. The "active answers" section of the HP webpage provides two types of online calculators: • Power Calculator - Calculates the power requirements for a single DL360 G3 server • Rack/Site Installation Preparation Utility - Calculates the power, vertical space, and air flow/cooling requirements for a complete rack of servers. Power Calculator Utility The Power Calculator utility (Figure 5) computes the power requirements for a single DL360 G3 server. Using drop-down menus, the user selects the number of CPUs, memory amount, hard drive type and amount, and PCI card compliment of the server. Each configuration change is re-calculated instantly, and a yellow warning message will be displayed if a particular parameter will not work or seriously impede performance. 14
