摘要： Embodiments of the present invention include computer-implemented methods for selectively applying remedial actions, according to a predefined order, for reducing the error rate in a computer memory system. In one embodiment, an ordered set of remedial actions are sequentially invoked in response to a single-bit error (SBE) in a DIMM reaching successive error thresholds. For example, in an air-cooled system, the remedial actions may include dynamically increasing a DIMM refresh rate, dynamically increasing a rate of airflow used to cool the DIMMs, and dynamically throttling the DIMMs. The remedial actions may be layered as they are successively invoked, to provide a cumulative remedial effect. At least two of the remedial actions may be simultaneously invoked in response to a multi-bit error rate reaching an associated threshold.

摘要： DIMMs are cooled by positioning a thermally conductive base between adjacent DIMMs. The thermally conductive base, such as a heat pipe or metal rod, receives heat from the DIMMs through thermally conductive elements that are selectively biased outward against the installed DIMMs. The base transfers the heat to a liquid conduit extending along the end of the DIMMs, where a circulating liquid carries away the heat. The thermally conductive elements provide an adjustable span to accommodate variations in distance between the DIMM surfaces. Embodiments of the invention may be installed without extending above the height of the DIMM.

摘要： Apparatus and method are provided for facilitating air-cooling of an electronics system employing a vapor-compression heat exchange system, and front and back covers. An evaporator housing of the heat exchange system is mounted to a system housing of the electronics system and extends at least partially between air inlet and outlet sides of the system housing. The evaporator housing includes air inlet and outlet openings, and an evaporator. The front cover is mounted to the system or evaporator housing adjacent to the air inlet side or air outlet opening, and the back cover is mounted to the system or evaporator housing adjacent to the air outlet side or air inlet opening. Together, the system housing, back cover, evaporator housing and front cover define a closed loop airflow path passing through the system housing and evaporator housing, with the vapor-compression heat exchange system cooling air circulating therethrough.

摘要： One embodiment involves detecting the fouling of an air filter used to filter airflow entering a computer system. An expected airflow rate is obtained from a current fan speed. An expected temperature rise between two positions is computed as a function of the expected airflow rate and the power consumption of heat-generating components, such as servers. An actual temperature rise is obtained from temperature sensors. An electronic alert is automatically generated in response to the actual temperature rise exceeding the expected temperature rise by a setpoint. Different setpoints may be used to trigger distinct electronic alerts.

摘要： Detecting a fouled air filter in a computer equipment enclosure that includes an air filter, a supply plenum connecting the air filter and the computer equipment enclosure, a fan operating at a current fan speed, and a filter monitoring module connected for data communications to a management module. Detecting a fouled air filter according to embodiments of the present invention includes calculating, by the filter monitoring module, a pressure differential across the air filter; determining, for the current fan speed by the filter monitoring module in dependence upon a pressure differential profile for the air filter, whether the calculated pressure differential across the air filter exceeds a predetermined threshold value; and if the calculated pressure differential across the air filter exceeds the predetermined threshold value, reporting, by the filter monitoring module to the management module, that the calculated pressure differential across the air filter exceeds the predetermined threshold value.
