摘要： A system for characterizing vibration of a rack structure having at least one hard disk drive disposed therein and a vibration exciter operatively associated with the rack structure includes one or more computers. The one or more computers are configured to command the vibration exciter to provide vibration input to the rack structure and to command a plurality of reads from the at least one hard disk drive such that, for each of the plurality of reads, data stored on the at least one hard disk drive is retrieved from the at least one hard disk drive. The one or more computers are also configured to obtain read rate information related to the plurality of reads and to identify at least one resonant frequency of the rack structure based on the read rate information.

摘要： A method for processing signals from a data server system including generating, by a monitoring module on a monitoring facility, a plurality of frequency data items, where the monitoring facility comprises a central processing unit, obtaining, by the monitoring module, a first signal value from the data server system, where the signal value is a measurement of an element of the data server system, and calculating a plurality of fit errors for the plurality of frequency data items using the first signal value. The method further includes selecting a frequency data item of the plurality of frequency data items with a lowest fit error to obtain a selected frequency data item, removing a cyclic component of the first signal value using the selected frequency data item to obtain a first processed signal value, and displaying the first processed signal value on a graph.
