Patent ID: 7761244

Claim:
A method for mitigating the effects of multiple vibration sources on a set of hard disk drives (HDDs) within a computer system, the method comprising: identifying a target HDD in the set of HDDs, wherein performance of the target HDD is affected by mechanical vibrations; identifying one or more primary vibration sources that affect the performance of the target HDD from the multiple vibration sources; for each of the primary vibration sources, measuring a first time-domain signal associated with the operation of the primary vibration source using a first vibration transducer associated with the primary vibration source; measuring a second time-domain signal associated with the target HDD using a second vibration transducer associated with the target HDD, wherein measuring the first and second time-domain signals involves measuring the first and second time-domain signals during a same time period; and computing a cross-power-spectral-density (CPSD) between the first and the second time-domain signals; and selectively mitigating the primary vibration sources based on the CPSDs between the primary vibration sources and the target HDD.
