Abstract: A fire resistant and water resistant enclosure for an operable computer digital data storage device is provided. The enclosure has walls made of gypsum or concrete and, in one embodiment, has two small ventilation openings which remain open during normal operation of the digital data storage device and during the presence of fire. This embodiment has no moving parts. In the presence of fire, air and superheated steam from inside the enclosure expand and flow outwardly through the ventilation passageways. As those gases flow outwardly, they simultaneously block or prevent the transfer of heat from the exterior fire inwardly through those passageways. A water resistant pouch or coating surrounding the storage device prevents damage from flood, water, steam generated by the insulation or smoke from passing through said passageways and damaging the storage device.

Abstract: Airflow bypass dampers made from a resilient material and systems including the resilient dampers. The dampers are secured in a chassis and extend into a deployed position to obstruct airflow through a component bay of a chassis in the absence of a component, such as a sever blade, within the selected bay. The airflow bypass damper bends into a retracted position in response to installing a component into the bay. It returns to its original shape and position when the component is removed. An air moving device moves air through a component installed in the chassis. A plurality of the resilient airflow bypass dampers may be secured in a plurality of bays of a chassis, each resilient damper moving independently of the others. The resilient material bends without permanent deformation. For example, the resilient material may include, without limitation, natural polymers, synthetic polymers and metals. A preferred damper has a curved cross-sectional shape.
