Drive vibration prevention system
Abstract:
A drive vibration prevention system includes a fan and a drive. The drive includes a vibration detection device and a vibration notification pin. A management engine is coupled to the drive and the fan. The management engine is operable to determine whether the vibration notification pin is being asserted in response to the vibration detection device detecting a vibration that exceeds a predetermined threshold. In response to determining that the vibration notification pin is being asserted, the management engine retrieves vibration data from the drive. The management engine then modifies a fan speed of the fan using the vibration data. Drives may be grouped into drive groups that output a single vibration notification signal to the management engine, and in response to the assertion of a vibration notification pin in the drive group, the management engine retrieves vibration data from each of the drives in that drive group.
