摘要： Methods, systems, and computer program products are provided for managing computer power consumption in a data center. Embodiments include monitoring aggregate power consumption of a plurality of computers in the data center, each of the computers being supplied power individually from a shared circuit in the data center; determining whether the aggregate power consumption exceeds a predetermined maximum threshold; if the aggregate power consumption exceeds the predetermined maximum threshold, selecting a number of computers for throttling in dependence upon priority; and throttling-down the selected computers, reducing the aggregate power consumption to a level below the predetermined maximum threshold. Some embodiments may also include determining whether the aggregate power consumption is below a predetermined minimum threshold; if the aggregate power consumption is below the predetermined minimum threshold, selecting a number of computers for throttling in dependence upon priority; and throttling-up the selected computers, increasing the aggregate power consumption to a level above the predetermined minimum threshold.

摘要： Embodiments include a power-efficient failover method. The method includes operating a primary server at a normal operating state in which program code is executed, and dynamically generating a backup of the results of the executed program code while in the normal operating state. The method further includes operating a redundant server at a reduced power state in which less power is consumed than in the normal operating state of the primary server. The workload of the primary server may be assumed according to the backup in response to a failure of the primary server. The power state of the redundant server is managed, including maintaining the redundant server in the reduced power state prior to detecting a failure of the primary server and increasing the power state of the redundant server and assuming the workload of the primary server in response to the failure of the primary server.

摘要： Multitasking in a hardware interrupt free environment. Event indicators are employed to multitask between processes of the environment. Processes to be multitasked register with one another, and then during processing, one of the processes toggles an event indicator to allow another process to execute. The toggling allows the processes to share resources in an interrupt free environment.

摘要： A level of indirection is utilized when writing to a microprocessor array structure, thereby masking hard faults in the array structure. Among other benefits, this minimizes the use of a backward error recovery mechanism with its inherent delay for recovery. The indirection is used to effectively remove from use faulty portions of the array structure and substitute spare, functioning portions to perform the duties of the faulty portions. Thus, for example, faulty rows in microprocessor array structures are mapped out in favor of substitute, functioning rows.

摘要： The monitoring of a worker process by an executive process. A worker process periodically sends a signal to an executive process, such as via a call to a heartbeat interface, which receives the signal and determines whether the worker process is improperly functioning. If the worker process is improperly functioning, the executive process terminates the worker process. The executive process may also examine the worker process for diagnostic purposes before terminating, or returning control to, the worker process.

摘要： In one embodiment, a computer system has a plurality of chassis interconnected by cables. Each cable initially connects a unique port pair consisting of a port of one chassis and a port of another chassis. The disconnection of cables is monitored, including electronically recording a disconnection sequence in which the port pairs are disconnected by removing each cable from at least one port of the respective port pair. Visual guidance is provided for re-cabling the computer system by sequentially identifying the port pairs in a reversal of the disconnection sequence, wherein identifying each port pair includes illuminating visual indicators associated with the ports of each port pair with a matching illumination pattern.
