Patent number: 9257818Abstract: Computational enclosures may be designed to distribute power from power supplies to load units (e.g., processors, storage devices, or network routers). The architecture may affect the efficiency, cost, modularity, accessibility, and space utilization of the components within the enclosure. Presented herein are power distribution architectures involving a distribution board oriented along a first (e.g., vertical) axis within the enclosure, comprising a power interconnect configured to distribute power among a set of load boards oriented along a second (e.g., lateral) axis and respectively connecting with a set of load units oriented along a third (e.g., sagittal) axis, and a set of power supplies also oriented along the third axis. This orientation may compactly and proximately position the loads near the power supplies in the distribution system, and result in a comparatively low local current that enables the use of printed circuit boards for the distribution board and load boards.Type: GrantFiled: August 11, 2014Date of Patent: February 9, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Eric C.
