Abstract: Disclosed herein is an algorithm that leverages the unique features and capabilities of a DCC-DAS in order to perform automatic measurements of uplink noise, PIM, and any uplink interference. Once an interference in the uplink is detected, this algorithm may automatically measure its parameters such as frequency, intensity, bandwidth, etc., and identify the source of the problem. It may automatically isolate and identify which element or cable of the DCC-DAS is the root cause of the problem or also which external source is generating the problem.

Abstract: To avoid the need to operate in-chassis fans to cool rack-mounted servers in a data center, the data center is arranged into a hot aisle and a cold aisle. The cold aisle is adjacent to a first side of the rack mounted servers and receives cold air from a cold air supply unit. The hot aisle is adjacent to a second side of the rack-mounted servers and has a lower pressure than the cold aisle. Because of the pressure difference between the cold aisle and the hot aisle, cold air flows through the rack-mounted servers, cooling electronic equipment therein, into the hot aisle. Control systems are used to obtain sufficient cooling.

Abstract: In a data center, components of a server are located on a different circuit board than the processor. For example, components such as a network interface controller, storage devices, power supply, and memory are located on one or more circuit boards different than the circuit board on which the processor is located. Having server components on different circuit boards allows the components to be updated on different schedules, reducing resource consumption caused from tying component updates to processor updates. Locating server components on separate server boards also allows virtualization of server components included in a server rack.

Abstract: A file storage system may be implemented by coordinating non-exhaustible and exhaustible storage devices. The exhaustible storage devices may be lower grade flash based storage devices. The non-exhaustible storage devices may be storage devices based on magnetic recording mechanisms or higher grade flash storage. The file storage system may store received content items on the exhaustible storage devices. The file storage system may additionally store metadata for the content items and/or the file storage system on the non-exhaustible storage devices. During operation, the file storage system may globally optimize the content items on the exhaustible storage devices such that more heavily accessed items are moved to exhaustible storage devices that have experienced relatively few data operations. The file storage system can move less frequently accessed content items to exhaustible storage devices that have experienced a relatively large number of data operations.

Abstract: The need for an uninterrupted power supply (UPS) in a data center is obviated by tying a DC voltage from a backup power source directly to the motherboards of multiple servers in the data center. AC power received from a power utility service is converted into a lower voltage by a site transformer and then provided to one or more power distribution units at a site. The power distribution units supply power to a plurality of servers, which include power supplies that convert the AC electrical power to DC electrical power for use by the servers' motherboards. In the event of a failure of power from the utility service, the backup power source provides DC electrical power to the motherboards, e.g., for sufficient time to start up a generator to provide power in place of the utility service.
