Abstract: A self-powered processing device comprises both a processing device and a power generator that are physically, electrically, and thermally coupled to one another. The power generator can be a fuel cell that can be manufactured from materials that can also support processing circuitry, such as silicon-based materials. A thermal coupling between the power generator and the processing device can include a thermoelectric either generating electrical power from the temperature differential or consuming electrical power to generate a temperature differential. A computing device with self-powered processing devices also includes energy storage devices to store excess energy produced by the self-powered processing device and provide it back during times of need. The self-powered processing device comprises either a wireless or wired network connection, the latter being connectable to a slot on a backplane that can aggregate multiple self-powered processing devices and provide fuel delivery paths for them.

Abstract: A bid-based network sells network capacity on a transaction-by-transaction basis in accordance with bids placed on transactions. A transaction is the transmission of a quantum of data across at least some portion of the network, where the quantum of data can be as small as a single packet. Bids for network capacity are ranked in order of monetary value, or other criteria relevant to the network service provider. The amount charged to the highest bidder is based on the maximum bid of the next highest bidder. Bids are evaluated on a real-time basis at the time when the link is ready to transmit data. An automated system makes individual bids at each link through which data is transmitted and can take into account additional criteria that can be specified as part of the bid information, including latency and routing requirements. Bid information is passed with data through the network.

Abstract: Computing devices receive power from multiple fuel cells, consuming natural gas and outputting electrical energy natively consumable by the computing devices. The fuel cells are sized to provide power to a set of computing devices, such as a rack thereof. The computing devices of a failed fuel cell can receive power from adjacent fuel cells. Additionally, the fuel cells and computing devices are positioned to realize thermal symbiotic efficiencies. Controllers instruct the computing devices to deactivate or throttle down power consuming functions during instances where the power consumption demand is increasing faster than the power being sourced by fuel cells, and instruct the computing devices to activate or throttle up power consuming functions during instances where the power consumption demand is decreasing faster than the power being sourced by the fuel cells. Supplemental power sources, supplementing the fuel cells' inability to quickly change power output, are not required.

Abstract: A computer system comprising a motherboard and a power supply having an associated power management bus controller with memory storing the power capacity of the associated power supply. A power circuit provides power from the power supply to the motherboard, wherein the motherboard has a processor and a baseboard management controller. The system further comprises a power management bus providing communication between the baseboard management controller and the power management bus controller associated with the selected power supply, wherein the power management bus controller provides the stored power capacity to the baseboard management controller. This allows the baseboard management controller to limit operation of the processor to control the amount of power consumed from exceeding the power capacity of the selected power supply. The power capacity of the power supply may be sent to the baseboard management controller in response to booting the motherboard.

Abstract: A data processing system and method analyze the performance of its components by obtaining measures of usage of the components over time as well as electrical requirements of those components to recommend an optimal configuration. The location in the system and the time duration that any one or more components is in a performance-limiting or bottleneck condition is determined. Based on the observed bottlenecks, their times of occurrence and their time duration, more optimal configurations of the system are recommended. The present invention is particularly adapted for use in data processing systems where a peripheral component interconnect (PCI) bus is used.

If the current configuration is not optimized, alternate configurations are generated and analyzed to find at least one optimized alternate configuration. If an optimized alternate configuration is found, the system optimizer notifies a user. However, if at least one optimized alternate configuration is not found, the testing criteria is altered and the set of generated alternate configurations are analyzed utilizing the altered testing criteria.

Abstract: A method and system for accessing data in a redundant array of inexpensive disks (RAID) subsystem is disclosed. The RAID subsystem includes a RAID controller having a cache and a plurality of disks. The method and system include utilizing the cache in a write back mode if the RAID subsystem is lightly loaded. In write back mode, the data is written to the cache prior to storing the data on at least one disk of the plurality of disks or prior to outputting the data from the RAID subsystem. The method and system also include utilizing the cache in a write through mode if the RAID subsystem is heavily loaded. In the write through mode, the data is written directly to at least one disk of the plurality of disks and, in a preferred embodiment, at the same time written to any cache buffer. Thus, data is written to the disks without the delay associated with managing a full cache when in write back mode required to flush an existing cache buffer to make a free buffer available.

Abstract: A method of optimizing server hardware performance and predicting server hardware bottlenecks monitors server hardware utilization parameters over a selected time period and computes the averages of the measurements. The method then compares the computed averages to thresholds. If some of the computed averages are equal to or greater than the threshold, the method reports a performance bottleneck and provides a recommended solution for the bottleneck. The method predicts a future server hardware performance bottleneck by computing running averages of the measured server utilization parameters. The method uses a linear regression analysis to determine a trend in the running averages and compares the trend to threshold values to predict the occurrence of a performance bottleneck.
