A modular compute platform including an enclosure, a first module including an application specific integrated circuit, the first module being disposed in the enclosure, a second module including an input/output device, the second module being disposed in the enclosure, the input/output device connected to the first module through a first cable, and a third module including a media device disposed in the enclosure, the media device connected to the first module through a second cable.

Modular server design

Software intrusion protection systems to prevent remote access to sensitive data are very prevalent. In some cases, additional physical access protection may also be desired. By preventing physical access to a system an intruder may not be able to physically 'steal' component parts of the system and then obtain their contents (or design criteria) at a remote site (e.g., after the physical theft). Monitors are provided to detect potential access to a secure computer system and identify if inappropriate access to the secure computer system is obtained (or is imminent). In a case where unauthorized access is predicted, warnings and alerts may be sent prior to an actual breach. Upon determination that a breach may be likely to occur, techniques to protect data (e.g., erasure, destruction, etc.) and component parts may be initiated. Sensors monitor internal and external physical environmental conditions to assist in detection of intrusion.

Intrustion detection and notification device

An example device in accordance with an aspect of the present disclosure includes a plurality of memory segments corresponding to at least one memory channel of a computing system that is to receive a memory module. A performance attribute of an Advanced Configuration and Power Interface (ACPI) table is set to indicate performance of at least one of the plurality of memory segments, and is usable for memory allocation by an operating system memory manager.

Performance attributes for memory

A system and method for a computing device having a processor, a memory module including volatile memory for random access memory (RAM), and an integrated circuit to intercept an error signal from the processor, the intercept delaying a system shutdown of the computing device. Firmware is executed by the processor to copy contents of the volatile memory to a non-volatile memory during the delay of the system shutdown.

Data copy to non-volatile memory

Examples relate to a modular server architecture that comprises a server chassis, a plurality of independent resource modules releasable attached to the server chassis a memory semantic protocol controller connected to the plurality of independent resource modules. Each one of the resource modules of the plurality of resource modules has a distinct Printed Circuit Board (PCB). The memory semantic media controller is to manage the plurality of independent resource modules.

Modular server architectures

Example implementations relate to a server node shutdown. For example, a system includes a control module and a secondary power supply. The control module includes a detect engine to detect an even that triggers a sequenced shutdown of a server node and prevent execution of the sequenced shutdown and execution of a data transfer. The control module also includes an initiate engine to initiate a data backup process, by a basic input/output system (BIOS) of the server node, to write data from a volatile memory location of the server node to a non-volatile memory location of the server node. The secondary power supply is to support the data backup process.

Server node shutdown

A printed circuit board having a substrate layer, at least one electrically conductive trace disposed on the substrate layer, and a solder mask layer disposed over the substrate layer and the electrically conductive trace, wherein the solder mask later includes a void region over at least a portion of the electrically conductive trace. Also, a method of optimizing printed circuit board designing including selecting printed circuit board data comprising at least a solder mask layer area, varying the solder mask layer area, determining an insertion loss value for each varied solder mask layer area, comparing the insertion loss values for each varied solder mask layer area, and selecting a solder mask layer area based on the comparing.

Solder mask void regions for printed circuit boards

A computing device having firmware, an uninterruptible power supply (UPS), and a memory module with volatile memory. Firmware tasks are prioritized to elevate tasks associated with the copying of the contents of the volatile memory to the nonvolatile memory external to the memory module during the loss of main or primary power.

Prioritizing tasks for copying to nonvolatile memory

In one example, a processor may include a processor core with a central processing unit as well as a processor cache separate from the processor core. The processor may also include flushing circuitry. The flushing circuitry may identify a power loss event for the processor. In response, the flushing circuitry may selectively power the processor by providing power to the processor cache but not to the processor core. The flushing circuitry may further flush data content of the processor cache to a non-volatile memory separate from the processor.

Flushing data content in response to a power loss event to a processor

An apparatus in accordance with one example includes a battery module in a dual in-line memory module (DIMM) form factor. The battery module is insertable in a DIMM slot of a host device to provide backup power to a plurality of loads of the host device.

Dual in-line memory module (DIMM) form factor backup power supply

Example implementations relate to backup power communication. For example, a system for backup power communication can include a shared backup power supply coupled to a node, a plurality of loads supported by the node, and a pass-through device to support multi-master communication between the shared backup power supply and the plurality of loads.

Backup power communication

Example implementations relate to backup power supply support. For example, a backup power supply support system can include a shared backup power supply controlled by a backup power control module and a support switch coupled to the shared backup power supply. The support switch enables a transition from a primary power supply to the shared backup power supply and the support switch includes system firmware. The system firmware detects a primary power supply compromise, isolates a hardware switch from the shared backup power supply, enables the hardware switch, and transitions to the shared backup power supply.

Backup power supply support

A printed circuit board (PCB) having a thermal relief pad around at least one via. The thermal relief pad includes at least four thermal cut-outs and at least four conductive bands. The at least four conductive bands are formed between the at least four thermal cut-outs such that adjacent conductive pads are orthogonal to each other. Each pair of mutually opposite conductive bands have substantially equal lengths and each pair of adjacent conductive bands have unequal lengths.

A system and method for voltage and frequency margining of a digital system such as a digital processing system. Various implementations of the present invention may be utilized to programmatically vary the voltage and or frequency utilized by one or more components within a processing system to effect changes in system and or component margining.
