Abstract
A data storage enclosure can employ an acoustic baffle for the purpose of reducing performance degradation in a data storage device, such as a rotating medium hard disk drive. A storage enclosure may house a plurality of data storage devices and at least one cooling feature. One or more acoustic baffles may be positioned between the at least one cooling feature and the plurality of data storage devices. The acoustic baffle can separate a first sound pressure region that is proximal the at least one cooling feature from a second sound pressure region that is proximal the plurality of data storage devices.
Claims20
An apparatus comprising an acoustic baffle separating a first sound pressure region proximal a cooling feature of an enclosure from a second sound pressure region proximal a data storage device in the enclosure, the acoustic baffle comprising a plurality of protrusions each extending from a base to define a plurality of air passages, each air passage of the plurality of air passages shaped to move air in multiple different directions relative to a mid-plane of the base.
A method comprising:
- positioning an acoustic baffle between a data storage device and a cooling feature in an enclosure, the acoustic baffle comprising a plurality of protrusions each extending from a base to define a plurality of air passages, each air passage of the plurality of air passages shaped to move air in multiple different directions relative to a mid-plane of the base;
- activating the cooling feature to move air and create a first sound pressure level proximal the cooling feature;
- and
- reducing the first sound pressure level to a second sound pressure level with the acoustic baffle, the second sound pressure level being proximal the data storage device.
