Abstract

Some embodiments of the present invention provide a system that generates a composite vibration profile in a frequency range for a computer system. First, a vibration spectrum in the frequency range is measured for a test computer system in each configuration in a set of configurations. Then, the composite vibration profile for the computer system is generated based on the measured vibration spectra.
