A power distribution system includes a plurality of loads and a plurality of power sources. The power distribution system also includes an interconnect arrangement including a plurality of interconnects. The interconnects connect each load to a given number of different ones of the sources so that each load is fully powered notwithstanding failure of any one of the sources.

Power distribution system utilizing redundant AC sources or DC sources

A system controls operating system images for a group of diskless servers and comprises an operating system builder, an operating system image manager and a run-time configuration and management tool. The operating system builder is configured to create a binary image of an operating system and modify components of the image by automated operation. The binary image is operative as common base operating system image for multiple servers. The operating system image manager discovers and manages a set of diskless servers in conjunction with a server manageability interface and a boot server. The run-time configuration and management tool for the diskless server set is configured for high-availability management, server and application health monitoring, and enforcing a security protocol between a network and a host server and individual diskless servers.

Methods, apparatus and articles of manufacture to control operating system images for diskless servers

One embodiment disclosed relates to a system for power management of a group of computers. The system includes server side infrastructure (SSI) circuitry at each computer in the group and a centralized power management module (CPMM). The SSI circuitry includes local monitoring circuitry coupled to a central processing unit (CPU) of the computer. The CPMM has a management link to the SSI circuitry at each computer in the group. The local circuitry at each computer monitors power consumption at the CPU of that computer and transmits power consumption data to the CPMM. The CPMM applies a set of rules to the power consumption data to determine when and at which computers to enable and disable a CPU power throttling mode.

Rack-level power management of computer systems

One aspect of the present invention provides a server card that is removably insertable into a server chassis. An electronic power switching mechanism is disposed on the server card and is configured to cause three power states of the server card including a fully operational state, a standby state, and a fully shutdown state. In the fully operational state, a system power of the server card is enabled and a standby power of the server card is enabled. In the standby state, a system power of the server card is disabled and the standby power of the server card is enabled. In a shutdown state, the system power of the server card is disabled and the standby power of the server card is disabled.

Server card power switch

A component for insertion into a hole in a multiple-layer substrate enables impedance matching of the substrate. The component comprises a conductive ground core arranged to extend through multiple-layers of the substrate when the component is inserted, a dielectric layer laterally encasing the conductive ground core, and a signal conductor layer coupled lateral to the dielectric layer.

Component for impedance matching

A power distribution system provides power source redundancy. The system includes a bank of loads and first and second groups of power sources. An interconnect arrangement includes a plurality of interconnects that connect each load to one or more sources of both the first and second groups of sources so as to be fully powered by sources of both the first and second groups of sources and such that if any one source or all sources of one of the groups of sources fails, all of the loads remain fully powered.

Power distribution system having redundant mixed sources and method

The present invention provides a method and system that is capable of identifying an event type from a plurality of event types to direct an event translator to determine an event occurrence based on the event type. A method is provided for identifying the event type from a plurality of event types, determining an event occurrence based on the event type; and communicating the event occurrence. A system is also described.

Method and system for supporting a plurality of event types

The present invention provides a margin testing system, incorporated in an electronic system (e.g., a computer system), that includes a controller, a frequency control module, and a voltage control module, and a fault bypass module. In response to commands from the controller, the frequency control module and/or the voltage control module can set a test clock frequency and/or a test voltage for application to one or more components of the electronic system to elicit system response to these test values. The response of the system at each test value can be monitored, e.g., by executing a diagnostics software, and analyzed. The fault bypass module can mask fault signals during margin testing to ensure that these signals will not disrupt margin testing of the system.

Method and construct for enabling programmable, integrated system margin testing

One embodiment disclosed relates to an apparatus for supplying redundant power to a plurality of computer systems. The apparatus includes at least one bus bar, a plurality of power supplies each supplying power at a same voltage level, a plurality of power switches, and a power supply management controller. Power inputs of the computer systems are connected to the at least one bus bar. The power supplies are selectively connected to the at least one bus bar using the power switches. The power supply management controller controls the power switches such that the power is supplied redundantly to the computer systems.

Apparatus and method for real-time power distribution management

A power distribution system comprises a flexible power connector, a printed circuit board, a power supply, and a processor mounted on the printed circuit board. The flexible power connector comprises a first end electrically connected to the processor and a second end electrically connected to the power supply. The flexible power connector is configured with a length so that the power supply is in a spaced relationship relative to the processor and the flexible power connector includes a plurality of stacked layers arranged generally parallel to each other for distributed power transmission. These layers include at least two ground layers and at least one power layer. The power layer is sandwiched between two of the at least two ground layers.
