A modular network switch is disclosed. In an embodiment, removable interface modules and a switch circuit board (SMB) are housed in a chassis. Each of the interface modules includes a circuit board that is positioned in parallel with other interface modules. The SMB is oriented in a plane perpendicular to orientation planes of the interface modules, and the circuit boards are connected to the switch circuit board. A switch chip is electrically connected to SMB, and configured to switch network traffic between network connections of the interface modules. The chassis may include airflow regions separated by a divider with respective air intake vents. A power supply is housed in one of the regions and the SMB/interface modules are housed in another region. Power supplies provide power to the interface modules via a bus bar and provide power to the switch circuit board via a connection separate from the bus bar.

A system includes a coolant reservoir, a coolant pump, and a heat exchanger. The coolant reservoir is at least in part included in a data center rack and configured to hold a coolant. The coolant pump is configured to pump the coolant to a manifold configured to distribute the coolant to a plurality of different rack mounted devices. The heat exchanger is configured to cool the coolant via an ambient air of a data center.

An apparatus for minimizing installation footprints of expansion cards may include one or more expansion cards that include a short edge, a long edge that is longer than the short edge and is substantially perpendicular to the short edge, and an edge connector disposed on the short edge. The apparatus may also include an expansion-card frame dimensioned to 1) guide an expansion card toward a printed circuit board of a computing device at a substantially vertical orientation such that the short edge of the expansion card is disposed proximate the printed circuit board of the computing device and the long edge of the expansion card extends away from the printed circuit board and 2) removably couple the edge connector disposed on the short edge of the expansion card to the printed circuit board of the computing device. Various other apparatuses, systems, and methods are also disclosed.

An interface adapter may include a printed circuit board that includes an edge connector dimensioned to be inserted into an expansion socket of a computing device. The interface adapter may also include a plurality of modular computing components removably mounted to a top surface of the printed circuit board, where each modular computing component includes a connector dimensioned to be inserted into a socket of the printed circuit board and the connector of each modular computing component includes a pinout that is more compact than a pinout of the edge connector of the printed circuit board. In addition, the interface adapter may include one or more modular heatsinks coupled to a top surface of each modular computing component to facilitate heat dissipation from the top surface of the modular computing component. Various other apparatuses, systems, and methods are also disclosed.

In one embodiment, a pluggable module has fins along a length of its shell, and a planar gap on its shell in front of the fins. The fins may rise higher than an industry-standard pluggable module. The planar gap provides for a pressure drop as air reaches the fins, and thereby improves air flow. The pluggable module plugs into a port of a cage. A key pattern or rotating door on the port is configured to allow the pluggable module's fins to pass through, while also placing a height limit on non-fin regions of the shell.

Thermally-enhanced pluggable modules

An expansion card latching mechanism may include a base anchored to a printed circuit board. The latching mechanism may also include a latch coupled to the base such that a proximal end of the latch locks a proximal end of an expansion card to a fixed position on the printed circuit board. In addition the latching mechanism may include a compression spring wrapped around an arm of the latch such that the compression spring exerts a tension to maintain a locked position of the latch. Various other apparatuses, systems, and methods are also disclosed.

Technology is provided for a storage card adapter. The storage card adapter is used for housing storage cards (e.g., M.2 storage cards), and the storage card adapter can then be inserted into a drive bay. The storage card adapter includes a latch system that, when engaged, brings together the cover and carrier frame of the storage card adapter such that at least 75 lbs. of compressive force is applied to thermal pads disposed on either side of storage cards housed within the storage card adapter. The storage card adapters can also include removable spring arms suitable for use in engaging the storage card adapter with a drive bay.
