A stackable form-factor Peripheral Component Interconnect (PCI) device can be configured as a host controller or a master/target for use on a PCI assembly. PCI device may comprise a multiple-input switch coupled to a PCI bus, a multiplexor coupled to the switch, and a reconfigurable device coupled to one of the switch and multiplexor. The PCI device is configured to support functionality from power-up, and either control function or add-in card function.

Stackable form-factor peripheral component interconnect device and assembly

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 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

A computer system includes a chassis, a backplane coupled to the chassis and a card including a printed circuit board and an external connection bulkhead. The backplane extends in a vertical plane. The card has a major length and a minor width. The card is releasably connected to the backplane along the major length.

Computer system

A frequency manager automatically selects a clock frequency for each device or bus, or for a plurality of devices or buses, in a system, based on various factors and objectives. These factors and objectives can include optimizing performance of the devices without exceeding the system's power/thermal budget. The frequency manager can then control circuits that generate and provide clock signals having the selected frequency(ies) to these devices or buses. For example, in a system that is less than fully populated with devices, embodiments of the invention can select higher clock frequencies than a fully populated system would utilize. Some embodiments of the invention select higher clock frequencies for high-bandwidth devices than for low-bandwidth devices. Other embodiments use information about application programs that will be executed by systems, such as which devices these application programs will frequently access, to select higher clock frequencies for the frequently accessed devices. Yet other embodiments use information about whether the application programs are more memory or I/O intensive to allocate higher clock frequencies to either memory subsystems or I/O subsystems.

Bus clock frequency management based on device load

Bus clock frequency management based on device bandwidth characteristics

One embodiment of the invention includes a system for changing a bus configuration of a computing device. The system includes a first bus of the computing device, a second bus, and a third bus. Additionally, a multiplexing module is coupled with the first, second, and third buses. As such, the multiplexing module can selectively couple the first bus with the second bus or the third bus. A configuration module is coupled with the multiplexing module and controls its operation.

Device bandwidth management using a bus configuration multiplexer

A multi-computer system includes a chassis and a plurality of computers within the chassis operable independent of one another. Each computer has a plurality of subassemblies. The subassemblies of different computers are physically grouped together within the chassis based upon at least one of size, function or configuration.
