摘要： An embodiment of the present invention is directed to a memory module connector having a pivotable air baffle that controls airflow at the memory module connector. When the memory module connector is occupied by a memory module, the air baffle may rest on an upper edge of the memory module, substantially parallel to the system board and in general alignment with the airflow. When the memory module has been removed, the air baffle may be pivoted downward toward the connector base and into the airflow, to offset the reduction in airflow impedance caused by the removal of the memory module from the memory module connector.

摘要： One embodiment provides an error detection method wherein single-bit errors in a memory module are detected and identified as being a random error or a repeat error. Each identified random error and each identified repeat error occurring in a time interval is counted. An alert is generated in response to a number of identified random errors reaching a random-error threshold or a number of identified repeat errors reaching a repeat-error threshold during the predefined interval. The repeat-error threshold is set lower than the random-error threshold. A hashing process may be applied to the memory address of each detected error to map the location of the error in the memory system to a corresponding location in an electronic table.

摘要： Embodiments of the invention address deficiencies of the art in respect to digital signal transmissions and provide a novel and non-obvious fall time accelerator circuit for use in a USB interface. In one embodiment of the invention, the USB interface can include a USB port driver coupled to a host controller driver over a USB bus. The USB interface also can include a fall time accelerator circuit coupled to the USB bus between the USB port driver and the host controller driver. The fall time accelerator circuit can include a pulse signal generator coupled to an inbound signal path from the USB bus and arranged to generate a tunable pulse upon detecting a falling edge of a digital signal on the inbound signal path. The circuit further can include an active timer additionally coupled to the inbound signal path to hold the tunable pulse for a set period of time. Finally, the circuit can include a falling drive signal strengthener coupled to an outbound signal path from the pulse signal generator arranged to release the tunable pulse on the outbound signal path onto the USB bus.

摘要： A method and system are disclosed to enable and control power reduction in a blade/chassis system. A “maximum power reduction” attribute is stored in the VPD of the blade (or can otherwise be input to or retrieved or calculated by the management entity). The management module of the chassis in which the blades and power supplies are located uses this information to manage the power reduction of blades when the system is operating in an over-subscription mode and a power supply fails. If throttling is required, the system knows the amount of power reduction available for each blade and controls the throttling by spreading it out among the blades in the system so that, ideally, no blade will cease operation altogether.
