In one embodiment, a printed circuit board assembly comprises a printed circuit board including a processor, a heat sink mountable to the printed circuit board proximate the processor, and a memory module comprising logic instructions which, when executed by the processor, configure the processor to initiate a processor load routine, collect temperature gradient data during the processor load routine, and verify operation of the heat sink using the temperature gradient data.

A blade computer system includes a plurality of client devices, a blade enclosure having a plurality of blades therein, and an allocation server configured to allocate and deallocate the blades to and from the client devices. The blade enclosure is configured to place individual ones of the blades into or out of a sleeping state responsive to network messages received from the allocation server.

Power conservation technique for blade computer systems

In some embodiments, a computer network comprises a computing engine comprising a plurality of compute nodes and a load balancer coupled to the computing engine and coupled to a processor and a memory module, wherein the memory module comprises logic instructions which, when executed by the processor, configure the processor to receive, in the load balancer, a connection request from a first client computing device and a corresponding first persistence identifier for computing services provided by a first compute node managed by the load balancer, restore, on the first compute node, a stored computing session when the first persistence identifier is associated with the stored computing session, initiate, on the first compute node, a generic computing session when the first persistence identifier is not associated with any stored computing session, and assign the connection request from the first client computing device to the first compute node.

Restoring user states in dynamic computing environments

In a method for managing power consumption among compute nodes having respective power components, an increase in the power utilization of a first compute node of the compute nodes may be detected. In response to a detected increase, a sum of the power consumption levels of the compute nodes and the requested increase in power utilization of the first compute node is compared with an allowable power budget for a compute node pool. In addition, the power state of the first compute node power component is varied in response to the comparison.

Power consumption management among compute nodes

A blade enclosure includes a plurality of blades, an enclosure manager processing device and a bus coupling the enclosure manager processing device to each of the blades. Each blade has at least one power mode bit configured to be controlled by the enclosure manager processing device via the bus, and each blade is configured to cause itself to enter a working state or a sleeping state responsive to its at least one power mode bit.

A power management agent for managing power among electronic systems includes a module for predicting a future power consumption level of the electronic systems, a module for determining a power budget threshold for the electronic systems, and a module for determining whether a predicted future power consumption level will exceed the power budget threshold. The power management agent also includes a module for selecting one or more of the electronic systems to throttle in response to a determination that the predicted future power consumption level will exceed the power budget threshold and a module for selecting a throttle level to be applied to the selected one or more of the electronic systems to substantially prevent the future power consumption level from exceeding the power budget threshold.

Agent for managing power among electronic systems

In a method for estimating a condition of an electronic device, a model correlating at least one utilization metric of a component of the electronic device and the condition of the component to be estimated is formulated. In addition, the at least one utilization metric of the component is detected and the condition of the component and the electronic device are estimated based upon the formulated model with the detected at least one utilization metric as an input to the formulated model.

Estimating an electronic device condition

In one embodiment, a printed circuit board assembly comprises a heat sink having an electrically conductive mounting support and a printed circuit board including detection circuitry to detect an electrical connection between the electrically conductive mounting support and an electrically conductive receiver on the printed circuit board.
