Abstract: Self-contained server assemblies for housing servers or server blades and associated computing facilities are disclosed herein. In one embodiment, a server assembly includes an enclosure having an interior space housing a server blade, a dielectric coolant submerging heat producing components of the server blade, and a condenser assembly having a condenser coil in fluid communication with a vapor gap in the interior space. The condenser coil is configured to receive a coolant that removes heat from a vapor of the dielectric coolant in the vapor gap, thereby condensing the vapor into a liquid form to be returned to the server blade.

Abstract: The present disclosure relates to systems, methods, and computer readable media for optimizing resource allocation on a computing zone based on bursting data and in accordance with an allocation policy. For example, systems disclosed herein may implement a lifetime-aware allocation of computing resources to facilitate computational bursting on respective server nodes to prioritize different aspects of performance on the server nodes of a cloud computing system. The systems described herein provide a number of benefits, including, by way of example, facilitating an allocation policy that enables more densely packing virtual machines on respective server nodes, boosting individual virtual machine performance, and reducing a buffer of empty nodes that need to be maintained on one or more node clusters. This may include more densely packing virtual machines on respective server nodes.

Abstract: The discussion relates to cooling computing devices and specifically to managing two-phase cooling. One example can include a two-phase liquid immersion tank containing heat generating components and a liquid phase of a coolant having a boiling point within an operating temperature range of the heat generating components. The example can also include a stratification chamber fluidly coupled to the liquid immersion tank and configured to at least partially separate a gas phase of the coolant from other gases. The example can further include a condenser chamber fluidly coupled to the stratification chamber and configured to receive the gas phase of the coolant and cause the gas phase of the coolant to phase change back into the liquid phase of the coolant.

Abstract: A computing system includes a housing, processing circuitry, one or more additional components, and a cryogen evaporator plate. The housing includes a cryogen input port, a cryogen output port, and an interior chamber. The processing circuitry and the one or more additional components are in the interior chamber of the housing. The cryogen evaporator plate is thermally coupled to the processing circuitry and configured to receive a cryogen via the cryogen input port, cool the processing circuitry using the cryogen such that the cryogen is evaporated during the cooling of the processing circuitry to provide evaporated cryogen, and provide the evaporated cryogen into the interior chamber of the housing such that the evaporated cryogen is distributed over the one or more additional components to cool the one or more additional components.

Abstract: Immersion cooling enclosures with insulating liners and associated computing facilities are disclosed herein. In one embodiment, an immersion cooling enclosure includes a well formed in a substrate material, a lid in contact with and fastened to the well to enclose an internal space configured to contain a dielectric coolant submerging one or more computing devices in the internal space, and an insulating liner on the internal surfaces of the well. The insulating liner has a first side in contact with the dielectric coolant and a second side in contact with the substrate material of the well. The insulating liner is non-permeable to the dielectric coolant, thereby preventing the dielectric coolant from passing through the insulating liner to the substrate material.

Abstract: A removable immersion cooling infrastructure module can have a form factor equivalent to that of one or more of the computing devices being cooled by immersion cooling, thereby enabling the immersion cooling infrastructure module to be installed and removed in the same simplified and efficient manner. Moreover, the quantity of immersion cooling infrastructure modules can be varied depending on need, since the immersion cooling infrastructure modules and computing devices can be interchangeable within the openings designed to house the computing devices. An immersion cooling infrastructure module can comprise a filter, a pump that can circulate the immersion cooling liquid through the filter, a power supply and a controller, with the module receiving power, and, optionally, communications and other like connectivity, from the same source as the computing devices.
