    摘要: One embodiment of the present invention provides a technique for detecting anomalies during operation of a test computer system. Initially, a golden system and the test system are equipped with the same hardware configuration, wherein the golden system has gone through extensive qualification testing and is presumed to be operating correctly. Next, a deterministic load is executed on the golden system, and values for performance parameters from the golden system are monitored while the deterministic load is executing. Similarly, the deterministic load is also executed on the test system, and values for performance parameters from the test system are monitored while the deterministic load is executing. Next, pairwise differences are computed between values for performance parameters received from the test system and values for performance parameters received from the golden system. Finally, change detection techniques are applied to the pairwise differences to detect anomalies during operation of the test system.

    摘要: Embodiments of a computer system that includes a vibration-cancelling mode, and a related method and computer-program product (e.g., software) for use with the computer system, are described. During operation, a processor monitors operations in the computer system, and may select either the vibration-cancelling mode or an inactive mode based on the monitored operations. For example, the processor may select the vibration-cancelling mode when there are input/output-(I/O) intensive workloads to an array of one or more hard disk drives (HDDs) in the computer system. In this way, the processor may reduce the energy consumption associated with vibration-induced retries to the HDDs (and reduced I/O throughput) without increasing the energy consumption associated with active vibration damping at other times, such as when the computer system is idle or during processor-intensive workloads.

    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.
