摘要:
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.

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.

Methods and systems for controlling fluid coolant flow in cooling systems of computing devices are disclosed. According to an aspect, a method may include determining a temperature of a fluid coolant in a cooling system of a computing device. For example, a temperature of water exiting a cooling system of a server may be determined. The method may also include determining an operational condition of the computing device. For example, a temperature of a processor, memory, or input/output (I/O) component may be determined. Further, the method may include controlling a flow of the fluid coolant through the cooling system based on the temperature of the fluid coolant and/or the operational condition.

An apparatus for cooling a memory module installed in a computer system includes a liquid coolant conduit that is connected to a conduit support structure having a form factor selectively securable within a first preconfigured memory module socket of the computer system in order to position the liquid coolant conduit above the first socket. A heat pipe provides direct thermal contact between the liquid conduit and a heat spreader assembly in direct thermal contact with a face of the memory module. The apparatus may include a second heat pipe and second heat spreader assembly for similarly cooling a second memory module. In alternative configurations, the apparatus may cool memory modules on opposing sides of the conduit or memory modules that are both on the same side of the conduit.
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.

A system comprising a chassis that includes a plurality of modules and a fan assembly disposed in a distal end of the chassis for drawing air in parallel pathways through the plurality of modules. At least one of the modules is a compute module having a thermal sensor disposed to sense the temperature of air flowing across a processor mounted on a motherboard. The system further comprises a fan controller receiving output from the thermal sensor, wherein the fan controller operates the fan assembly to cool the plurality of modules and maintain the thermal sensor output within an operating temperature range. The fan controller controls the fan speed according to predetermined thermal profile settings associated with one of the compute modules received in the chassis. For example, the predetermined thermal profile settings may include a minimum fan speed, a maximum fan speed, and control loop feedback settings.

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.

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.
摘要:
A fansink arrangement for a laptop computer wherein two distinct patterns of air intake can be employed. Particularly, dual air intakes of the laptop can be managed and controlled depending upon an operating mode of the computer. Thus, when the computer is in a “stand alone” mode, only one air intake is employed while in a “docking” mode of the computer two air intakes are employed.
