Abstract: A multi-node server includes a plurality of nodes and a hard disk backplane. Each node includes a power supply module. The power supply module is built in the node. The hard disk backplane is connected to the plurality of nodes through a first connector. The power supply module of each node is connected to a power supply interface of another node through a second connector, where the first connector and the second connector are spaced apart, and air flowing from an air inlet of the multi-node server circulates through a spacing between the first connector and the second connector. A system backplane for connection is not arranged in the multi-node server, but is replaced with the first connector and the second connector with a relatively small volume.

Abstract: Embodiments of the present invention disclose a peripheral component interconnect express interface control unit. The unit includes a P2P module, configured to receive a first TLP from a RC or an EP and forward the first TLP to a reliable TLP transmission RTT module for processing. A reliable TLP transmission module is configured to determine, according to the received first TLP, sending links connected to active and standby PCIE switching units, and send the first TLP to the active and standby PCIE switching units through the sending links at the same time. A destination PCIE interface controller of the first TLP selectively receives the first TLP forwarded by the active and standby PCIE switching units and sends the first TLP to a destination EP or a destination RC. Thereby, reliable transmission of a TLP is implemented in a case of a PCIE switching dual-plane networking connection.
Abstract translation: 本发明的实施例公开了一种外围组件互连快速接口控制单元。 该单元包括P2P模块，用于从RC或EP接收第一TLP，并将第一TLP转发到可靠的TLP传输RTT模块进行处理。 可靠的TLP传输模块被配置为根据接收到的第一TLP确定连接到主用和备用PCIE交换单元的链路，并且通过发送链路同时将第一TLP发送到主用和备用PCIE交换单元。 第一TLP的目的地PCIE接口控制器选择性地接收由主用和备用PCIE交换单元转发的第一TLP，并将第一TLP发送到目的地EP或目的地RC。 因此，在PCIE交换双平面网络连接的情况下，实现TLP的可靠传输。

Abstract: A detection apparatus and a server are provided, where the apparatus is configured to detect whether a coolant heat pipe or a solenoid valve on the coolant heat pipe in a device is abnormal, and the apparatus includes a control chip. The control chip can control a working state of the solenoid valve. The control chip can further obtain a temperature of a component in the device. When it is detected whether the coolant heat pipe or the solenoid valve is abnormal, the control chip may obtain a temperature difference of the component in the device when the working state of the solenoid valve is controlled, and relatively conveniently determine whether the coolant heat pipe or the solenoid valve is abnormal based on the temperature difference.

Abstract: A computer device and a memory startup method of a computer are provided, where a basic input/output system initializes only a first part of memory in a memory initialization phase after a computer is powered on and started, so that an operating system can be started, and after the operating system is started, the basic input/output system continues to initialize memory that is not initialized in the computer, so that, in a startup phase, the computer can start the operating system without needing to wait until all memory has been initialized; therefore, a time from being started to entering the operating system is reduced for the computer, and a user can quickly enter the operating system to perform an operation, thereby improving user experience.

Abstract: The motherboard includes a basic computing unit and an extension unit. The basic computing unit is provided with a basic component and an external interface. The extension unit is configured to extend a function of the basic computing unit. The basic computing unit is coupled to a second external interface of the extension unit through a first external interface on the basic computing unit. A conventional motherboard is split, and a basic computing unit that includes only a processor subsystem and an extension unit that extends input/output and management are formed by properly dividing the processor subsystem and a peripheral system. Impact of an extension component on the basic computing unit is reduced, and the extension component can be flexibly replaced based on an actual requirement.

Abstract: A server power supply includes a first voltage input line, a second voltage input line, a ground cable, a switch, and a voltage limiting device. The switch and the voltage limiting device are connected in series and located between the first voltage input line and the ground cable. When a voltage of the first voltage input line is greater than a conduction voltage, both the switch and the voltage limiting device are in an ON state, so that the server is protected from a relatively high voltage. When the voltage of the first voltage input line decreases and is less than the conduction voltage after the voltage of the first voltage input line is greater than the conduction voltage, the voltage limiting device is in an OFF state.
