摘要： A method for generating a service action for a computer system is described. During the method, a longevity index value for a packaging technology (such as solder joints in a BGA) in the computer system is calculated using thermal and vibration telemetry data (which is collected in the computer system) and a longevity model. This longevity model may be based on accelerated failure testing of the packaging technology, field failures of the packaging technology in a group of computer systems (which includes the computer system) and/or thermal and vibration telemetry data for the group of computer systems. Furthermore, using the longevity index value, the service action for the computer system is determined. Based on the longevity index value, remedial action (such as repairs to the computer system) may be scheduled and performed.

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 schedules read operations for disk drives in a set of disk drives. During operation, the system monitors a write rate for write operations to a given disk drive in the set of disk drives, wherein vibrations generated by the read operations directed to disk drives in the set of disk drives are transmitted to the given disk drive. Then, the read operations for disk drives in the set of disk drives are scheduled based on the write rate for the given disk drive, thereby limiting interference between the write operations and the vibrations generated by the read operations.

摘要： One embodiment of the present invention provides a system that performs parallel grouping decomposition to facilitate expedited training of a support vector machine (SVM). During operation, the system receives a training dataset comprised of data vectors. The system then determines whether any data vector in the dataset violates conditions associated with a current SVM. Next, the system divides the violating data vectors into a number of subsets, thereby allowing parallel SVM training for each subset. The system subsequently builds an independent SVM for each subset in parallel based on the current SVM. The system then constructs a new SVM to replace the current SVM based on the SVMs built for each subset of violating data vectors.

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.
