Abstract: 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.

Abstract: An apparatus comprises an input node, a power rail to power a circuit load, and multiple current paths coupled in parallel with each other between the input node and the power rail. Each current path respectively provides a sense output to indicate current in the path and a current switch having a control input to control the current in the path. A control circuit, coupled to each control input individually and to each sense output individually, controls the current in each path individually based on the indicated current therein after a non-zero input voltage is initially applied to the input node, such that all of the paths concurrently conduct current from the input node to the power rail and collectively cause a total inrush current and corresponding voltage at the power rail to gradually increase.
Abstract translation: 一种装置包括输入节点，为电路负载供电的电力轨道以及在输入节点和电力轨道之间彼此并联耦合的多个电流路径。 每个电流路径分别提供感测输出以指示路径中的电流和具有用于控制路径中的电流的控制输入的电流开关。 控制电路单独地耦合到每个控制输入和单独的每个感测输出，在非零输入电压最初被施加到输入节点之后，基于其中指示的电流来单独地控制每个通路中的电流，使得所有的 路径同时将电流从输入节点传导到电力轨道，并共同引起总浪涌电流和电力轨道上的相应电压逐渐增加。

Abstract: Embodiments herein describe a computing system which is reconfigurable into different server configurations that have different numbers of sockets. For example, the computing system may include two server nodes which can be configured into either two independent servers (i.e., two 2S servers) or a single server (i.e., one 4S server). In one embodiment, the computing system includes a midplane which is connected to processor buses on the server nodes. When configured as a single server, the midplane connects the processor bus (or buses) on one of the server nodes to the processor bus or buses on the other server node. In this manner, the processors in the two server nodes can be interconnected to function as a single server. In contrast, the connections between the server nodes in the midplane are disabled when the server nodes operate as two independent servers.
