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： A system that facilitates distinguishing between soft errors and the onset of hardware degradation in a computer system. During operation, the system receives notifications of correctable-error events from a plurality of memory components. The system then averages numbers of correctable-error events from the plurality of memory components to generate an average number of correctable-error events across the plurality of memory components. The system subtracts the number of correctable-error events for a given memory component in a given time interval from the average number of correctable-error events to generate a residual number of correctable-error events for the given memory component in the given time interval.

摘要： Embodiments of the present invention provide a system that estimates the value of a virtual sensor. The system first samples values for performance metrics using external sensors that are coupled to a system and internal sensors that are built into the system. Next, the system generates an inferential sensing model for the system from the sampled values. Then, during operation, the system samples values of performance metrics using the internal sensors and uses the inferential sensing model and the sampled values from the internal sensors to estimate the values of performance metrics for removed external sensors (i.e., virtual sensors).

摘要： A system that records performance parameters from a computer system. During operation, the system periodically monitors performance parameters from the computer system and records the monitored performance parameters in a first storage space. Next, the system recurrently compresses the recorded performance parameters. This involves: (1) compressing the recorded performance parameters from the first storage space; (2) if insufficient space is available in a second storage space which is used to store compressed performance parameters, further compressing data in the second storage space to make room for the compressed performance parameters from the first storage space; and (3) storing the compressed performance parameters from the first storage space in the second storage space.
