摘要： One embodiment of the present invention provides a system that mitigates the effects of multiple vibration sources on a set of hard disk drives (HDDs) within a computer system. During operation, the system identifies a target HDD in the set of HDDs, wherein the performance of the target HDD is affected by mechanical vibrations. The system also identifies one or more primary vibration sources from the multiple vibration sources that affect the performance of the target HDD. Next, for each of the primary vibration sources, the system measures 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. The system also measures a second time-domain signal associated with the target HDD using a second vibration transducer associated with the target HDD. Next, for each of the primary vibration sources, the system then computes a cross-power-spectral-density (CPSD) between the first and the second time-domain signals. The system then selectively mitigates the primary vibration sources based on the CPSDs between the primary vibration sources and the target HDD.

摘要： Some embodiments of the present invention provide a system that accurately synchronizes signals related to the operation of a computer system. During operation, the system receives a first time-domain signal associated with a first system variable and a second time-domain signal associated with a second system variable from the computer system. The system then transforms the first and the second time-domain signals into a first frequency-domain signal and a second frequency-domain signal, respectively. Next, the system computes a cross-power-spectral-density (CPSD) between the first and second frequency-domain signals to obtain a phase angle versus frequency graph between the two frequency-domain signals. The system subsequently extracts the slope of the phase angle versus frequency graph, and uses the value of the slope to synchronize the first time-domain signal and the second time-domain signal.
