Abstract: The description relates to cooling electronic components, such as computing devices. One example includes a rack defining a volume and multiple sealed chassis modules removably fluidly coupled to a two-phase condenser tank via a vapor coupler and a liquid coupler. Individual sealed chassis modules can contain one or more electronic components immersed in two-phase coolant that when heated by operation of the electronic components experiences a phase change from a liquid phase to a gas phase and travels to the two-phase condenser tank via the vapor coupler and is cooled in the two-phase condenser tank until experiencing a phase change back into the liquid phase. Individual sealed chassis modules can be decoupled from the two-phase condenser tank without releasing two-phase coolant and an entirety of the multiple sealed chassis modules and the condenser tank are contained in the volume of the rack.

Abstract: A computer system with thermal management includes a boiler tank and a first computer component on a substrate in the boiler tank. A cooling fluid is positioned in the boiler tank and covering the first computer component. The boiler tank has a length, width, and height where the length and width of the boiler tank define a tank area that is no more than 50% larger than the substrate area.

Abstract: The discussion relates to disaggregated computing. One example can monitor multiple two-phase liquid immersion tanks. Individual two-phase liquid immersion tanks can contain multiple components of a single type of component type. The example can receive requests for virtual machines and allocate sets of components from individual two-phase liquid immersion tanks to work together to support the virtual machines requests.

Abstract: Techniques for controlling cooling of electronic components in computing facilities are disclosed herein. In one embodiment, a method includes detecting a pressure drop of a coolant flowing across multiple servers in an enclosure between the inlet and outlet manifolds and a supply temperature of the coolant at the inlet manifold. The method further includes automatically adjust operations of the pump to maintain the calculated pressure drop at or near a pressure-drop setpoint while automatically adjusting operations of the air mover to maintain the supply temperature at or near a temperature setpoint.

Abstract: Rack configurations provide increased storage device density without compromising cooling or immediate device availability. A device rack has a frame including posts which define an interior containing system board(s) with electronic device connectors. The system board is fixed relative to the frame, and the rack is devoid of sliding rails and cable management arms for the devices, thereby reducing rack weight and mechanical complexity. A vertical plenum within the rack between loaded system boards carries cooling air for the devices and may also permit use of a service robot to install or replace hot-pluggable hard disk drives or other devices, which can be arranged in columns. As one objective measure of the increased density provided, a connector density is at least a specified number of hundreds of mechanically and electronically releasably connectable electronic device connectors per cubic meter within the rack.

Abstract: Various technologies described herein pertain to racking equipment in a data center. A modular equipment rack system can include an upper track, a lower track, a vertical support, a power and network distribution unit, and a tray. The upper track and the lower track can respectively include incrementally spaced mounting locations at which the vertical support and the power and network distribution unit can be attachable. The tray can be attachable to the vertical support and the power and network distribution unit when the vertical support is attached to the upper track at a first upper mounting location and attached to the lower track at a corresponding first lower mounting location, and the power and network distribution unit is attached to the upper track at a second upper mounting location and attached to the lower track at a corresponding second lower mounting location.

Abstract: A computing device having partitions, and a method of communicating between partitions, are disclosed wherein at least one partition comprises: at least one register substantially always accessible to other partitions and capable of defining an address area; at least one address area that may be accessible to other partitions and is capable of being defined by the at least one register; and address areas other than the at least one accessible address area that are not accessible to other partitions. A method of processing interrupts comprising receiving an interrupt, assessing the origin of the interrupt, accepting, rejecting, or further assessing the interrupt, depending on its origin, when further assessing the interrupt, accepting or rejecting the interrupt depending on its contents, and forwarding accepted interrupts but not rejected interrupts to a target processor, and a device carrying out that method are also disclosed.

Abstract: Computing unit enclosures are often configured to connect units (e.g., server racks or trays) with a wired network. Because the network type may vary (e.g., Ethernet, InfiniBand, and Fibre Channel), such enclosures often provide network resources connecting each unit with each supported network type. However, such architectures may present inefficiencies such as unused network resources, and may constrain network support for the units to a small set of supported network types. Presented herein are enclosure architectures enabling flexible and efficient network support by including a backplane comprising a backplane bus that exchanges data between the units and a network adapter using an expansion bus protocol, such as PCI-Express.

Abstract: Water for data center uses is generated from the ambient air by a water generator that cools air below its dew point, thereby causing the water in such air to precipitate out. The water generator is powered by renewable energy sources that provide a sufficient amount of energy over an extended period of time, despite temporary interruptions. Heated air from the data center is exhausted so as to absorb moisture from the ambient air, with such heated air being capable of holding a greater amount of moisture, and is then directed through the water generator, thereby enabling the water generator to generate a greater amount of water. The level of water available is monitored and the water generator utilizes on-demand power sources to generate a greater amount of water so as to avoid emptying water storage units.
