Fan noise attenuation at hard disk drive in rack-mount

A sound-attenuation part, such as for use in a rack-mount server, is configured for insertion into an orifice of a backplane to which at least one data storage device is coupled. The sound-attenuation part may include one or more pipes extending from a mounting portion. The sound-attenuation part he...

Beschreibung
Zusammenfassung:	A sound-attenuation part, such as for use in a rack-mount server, is configured for insertion into an orifice of a backplane to which at least one data storage device is coupled. The sound-attenuation part may include one or more pipes extending from a mounting portion. The sound-attenuation part helps to attenuate acoustic noise, such as from a cooling fan, which might otherwise reach the data storage device, such as through airflow orifices constituent to a backplane that is positioned between the fan and the storage device, while maintaining enough airflow through the backplane for system cooling purposes. Thus, degradation of the head positioning accuracy within the storage device, caused by the forces associated with this acoustic noise, may be reduced.
