US Classification:

Abstract:

In one example, a data center may be built in modular components that may be pre-manufactured and separately deployable. Each modular component may provide functionality such as server capacity, cooling capacity, fire protection, resistance to electrical failure. Some components may be added to the data center by connecting them to the center's utility spine, and others may be added by connecting them to other components. The spine itself may be a modular component, so that spine capacity can be expanded or contracted by adding or removing spine modules. The various components may implement functions that are part of standards for various levels of reliability for data centers. Thus, the reliability level that a data center meets may be increased or decreased to fit the circumstances by adding or removing components.

International Classification:

H02J 9/00

US Classification:

307 64

Abstract:

Machines may be connected to power distribution units (PDU/STSs) in such a way that if one PDU/STS fails or is taken out of service, the machines' loads are shifted more-or-less evenly to the other PDU/STSs. Several PDU/STSs may be provided for a group of dual-corded machines. The two cords of each machine are connected to a pair of PDU/STSs. Different pairs of PDU/STSs may be used for different machines. In normal operation, each machine may draw part of its power through each of the two cords. If one PDU/STS to which a machine is connected fails or is taken out of service, the entire load on that machine may be shifted to its remaining cord. Since redistribution may be approximately even across PDU/STSs, tolerance for one PDU/STS failure can be implemented with relatively little over-sizing of the PDU/STSs.

International Classification:

H02J 9/00

US Classification:

307 68, 307 64

Abstract:

Unlike symmetric power feeds for dual-corded server environments, an asymmetrical power system for high availability environments uses an imbalanced power feed system, allowing lower cost implementation and, in some cases, reduced energy loss in the primary power supply path. One asymmetric power feed uses a direct power feed to supply normal operating power and uses a second system to supply back up power via a switched, conditioned, path with UPS and generator. Because the main power delivery is through the direct line, reliability and power loss are improved.

US Classification:

Abstract:

Super capacitor supplemented server power is described. In embodiments, a power system manager is implemented to monitor the capability of one or more power supplies to provide power for a server system. The power system manager can determine that the capability of the power supplies to provide the power is deficient, and then engage one or more super capacitor power modules to provide supplemental power for the server system to mitigate the power deficiency.

International Classification:

H02J 4/00
H01R 43/00

US Classification:

307 65, 29825

Abstract:

Equipment in a data center may be wired in a topology in which each piece of equipment is served by one Static Transfer Switch (STS). Each group of equipment is assigned a main UPS and a reserve UPS, which may be connected to an underlying power source such as a utility. The main UPS and the reserve UPS are connected to the first and second inputs of an STS. For dual-corded equipment, the first cord is served by the output of the STS, while the second cord is served by the main UPS without an intervening STS. Thus, if the main UPS fails, the STS transfers power to the second UPS, thereby allowing the first cord to be powered. The second cord, not being served by the STS, simply loses power, thereby doubling the power draw at the first cord at roughly the same time that the transfer occurs.

International Classification:

H02J 4/00

US Classification:

307 18

Abstract:

A power distribution system among a set of units (e.g., server blocks) may comprise, for each unit, a utility line and a unit generator, and a reserve generator providing failover transient performance and redundancy improvement to the power for the unit generators. The reserve generator may connect to the units via a reserve bus, and the unit generators may selectively connect to a wraparound bus connected to the reserve bus. When the failover load exceeds the available failover transient capability of one generator, one or more unit generators may (automatically or by operator selection) be connected with the wraparound bus to apply available transient capability to satisfy the excess failover load with minimal increase in power distribution resources and complexity.
