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.

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.

An apparatus and method is provided for conveying heat away from an electronic component. In one embodiment, a method positions a conformable thermal interface element in heat conducting contact with an electronic component. A heat conducting member is disposed within the conformable thermal interface element. The heat conducting member is coupled with a manifold so that the heat conducting member is in heat conducting contact with the manifold. The electronic component may be installed or removed without disassembly of the apparatus.

One embodiment provides a heatsink having a flexible base and height-adjusted cooling fins. The flexible base includes a single base plate, with cooling fins and heat pipes secured directly to an upper surface of the single base plate. The use of the single base plate allows the length of the cooling fins to be increased. The use of a single base plate also allows the base to flex when mounted at the outer region of the base plate to a circuit board using fasteners. The flexure of the base biases the heatsink against the heat-generating component. The flexure also displaces the outer cooling fins, and the length of the outer cooling fins is further increased to compensate for the anticipate displacement.

A fluid-cooled computer system includes a plurality of heat-generating components and a cooling system configured for supplying a cooling fluid at a controlled cooling fluid flow rate to cool the heat-generating components. A temperature-based cooling control circuit includes a temperature sensor configured for sensing a temperature of the heat-generating components and control logic for increasing a cooling fluid flow rate in response to the temperature exceeding a temperature threshold. A power-based cooling control circuit is configured for identifying and quantifying an increasing power consumption trend over a target time interval and, during a period that the temperature of the electronic device does not exceed the temperature threshold, increasing a cooling fluid flow rate to the electronic device in response to the magnitude of the increasing power consumption trend exceeding a power threshold. In one option, the fluid-cooled computer system is a server and the heat-generating components include a processor.

A computer-implemented method comprises accessing historical operating data for a unit of information technology equipment, wherein the historical operating data includes power consumption, fan speed, inlet air temperature, workload, and any processor throttling events at various points in time. The method further comprises receiving user input selecting a fan speed, and using the historical operating data to determine a performance impact that is expected from operating the unit at the selected fan speed, where the power consumption is a proxy for performance. The estimated performance impact of the selected fan speed and one or more alternative fan speeds is then displayed.

Apparatus and method are provided for facilitating liquid cooling one or more components of an electronic subsystem chassis disposed within an electronics rack. The apparatus includes a rack-level coolant manifold assembly and at least one movable chassis-level manifold subassembly. The rack-level coolant manifold assembly includes a rack-level inlet manifold and a rack-level outlet manifold, and each movable chassis-level manifold subassembly includes a chassis-level coolant inlet manifold coupled in fluid communication with the rack-level inlet manifold, and a chassis-level coolant outlet manifold coupled in fluid communication with the rack-level outlet manifold. The chassis-level manifold subassembly is slidably coupled to the electronics rack to facilitate access to one or more removable components of the electronic subsystem chassis. In one embodiment, the electronics subsystem chassis is a multi-blade center system having multiple removable blades, each blade being an electronics subsystem.
