An computing device for dual-access high-performance storage for BMC to host data sharing includes a storage device, a host input/output ('IO') domain hardware, a BMC that includes an external data connection, and a switch that includes a connection to the host IO domain hardware, a connection to the storage device, a connection to a root port in the BMC, and a connection to an end point port of the BMC. The switch is configured to connect the host IO domain hardware to the end point port of the BMC and configured to alternately connect the root port of the BMC to the storage device while uploading data from the external data connection to the storage device, and the host IO domain hardware to the storage device to permit the host IO domain hardware to access to the data uploaded from the external data connection.

Dual-access high-performance storage for BMC to host data sharing

A computing system includes a processor that has a processor cache built-in, and a non-volatile memory, such as a non-volatile dual-inline memory module (NVDIMM), which is being used as system memory within the computing system. The processor processes a transaction. If the computing system is connected to an uninterruptible power supply (UPS) (and the UPS is connected to a mains power source that is currently providing power), the transaction is committed without first flushing the processor cache to the non-volatile memory. If the computing system is not connected to a UPS (and is connected to a mains power source that is currently providing power), the transaction is not committed until the processor cache has been flushed to the non-volatile memory.

Methods, apparatus, and products are disclosed for optimizing a physical data communications topology between a plurality of computing nodes, the physical data communications topology including physical links configured to connect the plurality of nodes for data communications, that include carrying out repeatedly at a predetermined pace: detecting network packets transmitted through the links between each pair of nodes in the physical data communications topology, each network packet characterized by one or more packet attributes; assigning, to each network packet, a packet weight in dependence upon the packet attributes for that network packet; determining, for each pair of nodes in the physical data communications topology, a node pair traffic weight in dependence upon the packet weights assigned to the network packets transferred between that pair of nodes; and reconfiguring the physical links between each pair of nodes in dependence upon the node pair traffic weights.

An electronic device may be provided with more than one industry-standard type of AC power connector. The electronic device may be powered in any of a variety of locations by selectively exposing one of the power connectors selected according to an AC power outlet available at that location. A location-specific power cord may be used to connect the exposed power connector to the AC power outlet. The location-specific power cord may have, for example, a line socket at one end of a type that matches the exposed power connector, and a power plug at the other end of a type that matches the AC power outlet at the location. Predefined power settings appropriate for use with the AC power outlet and the exposed power connector may be automatically invoked.

Multi-capacity power supply for electronic devices

An arrangement for controlling a system generated noise level such that the same is adapted to an actual ambient noise level of the system environment. Internal noise generators will thus not run at a needlessly lowered rate than actually needed. For instance, by permitting a fan to run at a generally higher speed, the system will not needlessly undergo significant internal temperature increases. By the same token, CPU performance, to the extent that it represents a noise generator, will not be needlessly throttled.

A system and method are used for electronically detecting the accumulation of dust within a computer system using a capacitive dust sensor. The dust detection system may be implemented on a smaller computer, such as an individual PC, or in a more expansive system, such as a rack-based server system ('rack system') having multiple servers and other hardware devices. In one embodiment, each server in a rack system includes a capacitive sensor responsive to the accumulation of dust. The capacitive sensor may include one or more capacitive plates integral with a heatsink. As dust collects on the capacitive plates, the capacitance increases. When a capacitance setpoint is reached, indicating the dust has reached a critical level, an alert is generated. The alerts may be received by a management console for the attention of a system administrator. Each alert may contain the identity of the server generating the alert, so that the system administrator knows which server(s) are to be removed for cleaning.
