A voltage regulator dynamically adjusts the voltage distribution on a voltage rail based on multiple feedback measurements. The voltage regulator provides electrical power to a voltage rail at multiple power supply locations along the voltage rail. The voltage regulator obtains voltage measurements from multiple voltage sensing locations on the voltage rail and detects a spatially unequal voltage deviation in the voltage rail. The voltage regulator adjusts the electrical power provided to the voltage rail at each of the power supply locations to compensate for the spatially unequal voltage deviation in the voltage rail.

A solid state drive (SSD) device includes a cage with a top wall and a bottom wall spaced a distance from the top wall so as to define a cage interior between the top and bottom walls. In addition, at least 10% of an area along a side of the cage is open to the cage interior to permit airflow through the side of the cage. At least one printed circuit board (PCB), which includes at least one integrated circuit component, is also provided within the cage interior.

This disclosure relates to methods and systems for dynamically partitioning of PCIe disk arrays based on software configuration/policy distribution. In one embodiment, at least one PCIe switch has an input port operatively connected to a respective CPU and at least one output port. A multiplexer is connected between the output port(s) of the at least one PCIe switch and a PCIe disk array, for example an NVMe SSD, and is configured to connect the PCIe disk array in a first configuration to a single PCIe switch in either one-x4 port or two x2 port mode, or in a second configuration to two PCIe switches in x2 port mode. The multiplexer can dynamically switch between the first configuration and the second configuration on the fly. Switching can occur, for example, in response to a hot-swap of an NVMe SSD or a policy change.

A scalable multiprocessor computing system includes first and second computing devices and a link module connecting the computing devices. The link module includes a guide connector that aligns and couples the first computing device with the second computing device in an orientation in which a printed circuit board assembly (PCBA) support housing wall of the first computing device faces a PCBA support housing wall of the second computing device, a bracket member that is connected along corresponding lengthwise sides of the first and second computing devices, and a cable connector that provides a signal connection between the processor of the first computing device and the processor of the second computing device. The guide connector is connected to the bracket member.
