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.

• Calculations are based on active components exercised at 100% duty cycle,

generally allowing headroom for a typical installation design.

• Air volume calculations based on measurements taken in equipment operating with

an airflow chamber.

The ActiveAnswers section of the HP website provides two types of online calculators:

Note: Microsoft Excel must be installed on the system you are using to view these utilities.

• Power Calculator – calculates the power requirements for a single DL580 G2 server

• Site Preparation Calculator

– calculates the power, vertical space, and

airflow/cooling requirements for a complete rack of equipment

Power Calculator

utility

The Power Calculator utility (Figure 9) computes the power requirements for a single

DL580 G2 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 will seriously impede

performance.
