Abstract: To create secured offline data that is inaccessible by any computing devices external to a datacenter, a system includes an offline storage area for the datacenter. The offline storage area is distinct from a production area of the datacenter. The system also includes an offline storage unit that is configured to include storage media items that have been designated for offline storage. The storage media items include data from the datacenter. An automated system that operates within the production area of the datacenter is configured to transfer the storage media items into the offline storage unit. The system also includes a unidirectional security system that prevents the automated system from removing the storage media items from the offline storage unit after the storage media items have been moved into the offline storage area, thereby making the storage media items inaccessible to the automated system.

Abstract: Techniques for mitigating loss of vaporized working fluid in a two-phase immersion cooling system may be implemented using one or more supplemental condensers that facilitate condensation of vaporized working fluid when the immersion tank is open, and one or more vapor collection points that are in fluid communication with at least one supplemental condenser. One or more fluid displacement devices may be configured to create suction pressure at the one or more vapor collection points. One or more vents may be positioned in the door. The one or more vents may be configured to permit movement of air from outside the immersion tank into an interior portion of the immersion tank without permitting loss of vaporized working fluid. A directional blowing device may be configured to blow a gaseous substance against a computing device in a downward direction as the computing device is being pulled upward out of the immersion tank.

Abstract: A continuously growing physical structure may be generated by identifying a plurality of metrics associated with the physical structure. The plurality of metrics may include at least one of a shape of available physical space, a size of available physical space, a type of soil/earth of a location of the physical structure, a context of use of the physical structure, a climate of the location, or availability of resources associated with the location. The plurality of metrics may be analyzed to determine at least one of a rate of growth of the physical structure or a most suitable shape of the physical structure. Growth of the physical structure may then be generated according to at least one of the determined rate of growth of the physical structure or the determined most suitable shape of the physical structure. The identified plurality of metrics may then be monitored periodically.

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.

Abstract: Improving the operations of a computer system that is located within a power grid and that is associated with its own power sources. Past operational characteristics of the power grid are analyzed to derive learned characteristics for the power grid. Future operational characteristics of the power grid are also monitored. A prediction regarding a future load event associated with the power grid is then generated using the learned characteristics and the monitored characteristics. In response to this prediction, one or more operations are performed to balance the computer system with the power grid during the future load event, and to ensure a determined availability of services associated with the computer system during the future load event.

Abstract: Techniques are described herein that are capable of performing RFID-based navigation of an autonomous guided vehicle (AGV). An intended location of the AGV is determined based at least in part on a previously determined location of the AGV and further based at least in part on a calculated motion of the AGV from the previously determined location. The AGV includes an RFID device that is paired with RFID devices in an environment of the AGV. The RFID device of the AGV and one or more of the RFID devices in the environment may communicate in accordance with an RFID technique to enable the AGV to determine an actual location of the AGV. A reference location of the AGV on which navigation of the AGV is based is set to be the actual location rather than the intended location.

Abstract: Improving the operations of a data center that is located within a power grid and that includes its own power sources. Past operational characteristics of the power grid are analyzed to derive learned characteristics for the power grid. Current and/or future operational characteristics of the power grid are also monitored. A prediction regarding an upcoming, anticipated load for the power grid is then generated using the learned characteristics and the monitored characteristics. In response to this prediction, one or more mitigation operations are selected and then performed at the data center to ensure that the data center is adequately available. Some of these mitigation operations include, but are not limited to, causing the data center to consume more power, causing the data center's power sources to store more power, or causing the data center to migrate services and/or data to a different data center.
