A data storage system includes a chassis housing multiple data storage devices, such as hard disk drives, a compartment housing cooling fans, and an air plenum positioned between the fans and the storage devices. A multibody chambered acoustic attenuator, which may be installed in the air plenum, includes a plate part having airflow holes therethrough and may include a convex arched part having airflow holes therethrough and coupled with the plate part to form a chamber. Acoustic damping material lines an interior surface of the plate part and the interior and exterior surfaces of the arched part, and the airflow holes of the plate part and of the arched part are not aligned, such that direct acoustic emissions and reflections would contact the acoustic damping material and a circuitous airflow path is provided from the cooling fans to the storage devices, to reduce the acoustic sound pressure upon the devices.

Multibody chambered acoustic attenuator for a data storage system

A data storage system may include multiple data storage devices, such as solid-state drives, an enclosure housing the devices, and a thermal bridge positioned in a gap between and in contact with each of the enclosure and a device, where the enclosure is cooler than the device. Thus, heat is conducted away from a hot spot of the device and to the enclosure. The thermal bridge may be flexible enough to bridge different sized gaps, while stiff enough to generate contact forces applied to the enclosure and the device. For example, the thermal bridge may be constructed primarily of copper and configured to function like a compression spring.

Hot spot cooling for data storage system

To provide enhanced operation of data storage devices and systems, various systems and apparatuses are provided herein. In a first example, a data storage assembly includes an enclosure configured to house at least one data storage device and a fan assembly configured to provide airflow within the enclosure to ventilate the at least one data storage device. A plurality of acoustic waves emanate into the data storage device from one or more fans of the fan assembly during operation. An acoustic attenuation device is positioned within the enclosure and configured to deflect at least a first portion of the plurality of acoustic waves away from the at least one data storage device and absorb a portion of acoustic wave energy of at least a second portion of the plurality of acoustic waves.

Acoustic attenuation in data storage enclosures

Described herein is a first system that includes sleds each having sidewalls, a mounting plate, and a first cover. The first cover is movable relative to the sidewalls between a closed position and an open position. The first cover includes at least one first opening. The system additionally includes at least one data storage device fixed to each mounting plate. A first air gap is defined between the at least one data storage device and the mounting plate, and a second air gap is defined between the at least one data storage device and the at least one first opening of the first cover. The sleds are stacked together such that the first covers of adjacent sleds are directly adjacent each other, and the at least one first opening of the first cover of one sled at least partially overlaps the at least one first opening of an adjacent sled.

Stackable sleds for storing electronic devices

A mass storage chassis assembly configured to accommodate a predetermined number of storage drive failures is provided. The mass storage chassis assembly in one example includes a chamber, a plurality of working storage drives in the chamber, and an outside deck including one or more empty storage drive receptacles outside the chamber.
