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

additional extra capacity for typical installations.

• Air volume calculations based on measurements taken in equipment operating in an airflow

chamber.

The “active answers” section of the HP web page provides two types of online calculators:

•

Power Calculator – Calculates the power requirements for a single server

• Rack/Site Installation Preparation Utility – Calculates the power, vertical space, airflow, and cooling

requirements for a complete rack of servers.

Power Calculator Utility

The Power Calculator utility, as illustrated in Figure 6, computes the power requirements for a single

server. Using drop-down menus, you select the number of CPUs, amount of memory, hard drive type

and size, and PCI card compliment of the server. Each configuration change is re-calculated instantly.

The calculator displays a yellow warning message if a particular parameter will not work or will

seriously degrade performance.
