    • 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.
    • 用于表征具有设置在其中的至少一个硬盘驱动器的机架结构的振动的系统和与所述机架结构可操作地相关联的振动激励器包括一个或多个计算机。 一个或多个计算机被配置为命令振动激励器向机架结构提供振动输入并且从至少一个硬盘驱动器命令多个读取,使得对于多个读取中的每一个,存储在 从至少一个硬盘驱动器检索至少一个硬盘驱动器。 一个或多个计算机还被配置为获得与多个读取相关的读取速率信息,并且基于读取速率信息来识别机架结构的至少一个谐振频率。
