Abstract
System and methods are provided for reducing vibration in server or data storage units. An anti-vibration system according to the present invention includes one or more disk drives and one or more fans in a defined area, and a controller which is configured to control operation of each of the one or more fans. A nominal speed setting and a speed range are determined for the one or more fans, either commonly or independently with respect to each, and the fans are caused to be driven in accordance with the determined speed setting and speed range. As a result the occasions in which individual fan speeds are coincident with fixed frequency sensitivities for each disk drive are substantially minimized.
