Systems and methods for asynchronous-frequency tracking of disk drive rotational vibration (RV) performance with position error signal (PES)

摘要

Systems and methods are provided that may be implemented to provide a mechanical indicator to correlate magnetic disk drive IOP performance with features of mechanical and/or acoustic vibrational frequencies that are generated and captured or sensed outside of the disk drive itself. In one example, disk drive PES data may be collected concurrently with the capture of mechanical and/or acoustic vibrational data at different and progressive locations of vibration source, vibration path and vibration receiver in a disk drive operating environment, e.g., such as for disk drives installed within a server and/or storage chassis enclosure. In such case, PES threshold may be utilized to correlate performance of Drive IOP or drive servo-mechanical performance as a function of measured characteristics of vibration source/s that impart vibration to a disk drive.

1. A system, comprising:
at least one processing device; an information handling system chassis including at least one of an enclosure, a frame, or a combination thereof; at least one magnetic disk drive mechanically coupled to the chassis, the disk drive being configured to generate position error signals (PES) data, and to provide the PES data to the at least one processing device; one or more vibration sensor components configured to sense at least one of mechanical or acoustic vibrations simultaneously with the generation of the PES data by the disk drive, and to provide sensed vibration data representative of the sensed mechanical or acoustic vibrations to the at least one processing device; and at least one vibration source configured to operate at different operational levels that produce different corresponding frequencies of vibration; where the at least one processing device is configured to at least one of:
correlate a magnitude of the generated PES data with a frequency of the vibration data that is simultaneously sensed with the generated PES data, orcontrol or sense the current operational level of the vibration source and to correlate each of multiple different operational levels of the vibration source with a frequency of the vibration data that is simultaneously sensed or controlled while the vibration source is operating at the given operational level, ora combination thereof.
