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 generates a vibration profile for a rotational device in a computer system. During operation, the system sequentially sweeps a rotation speed of a rotational device over a range of rotation speeds. While driving the rotational device at each rotation speed, the system collects a time-domain vibration signal produced by the rotational device and subsequently computes a frequency spectrum of the time-domain vibration signal. In this way, the system generates a set of frequency spectra associated with the range of rotation speeds. Next, the system combines the set of frequency spectra to generate a composite vibration profile for the rotational device.

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.
