    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 chassis for an edge device includes a cabinet and a heat exchange component. The heat exchange component is disposed in a space enclosed by the cabinet. The space in the cabinet is divided into a first space and a second space for placement an electronic device. The heat exchange component performs heat transfer between the first space and the second space. A first air inlet and a first air outlet are disposed in the first space, and an airflow entering from the first air inlet flows through a first surface of the heat exchange component and exits from the first air outlet.

    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.

    Abstract: A storage system comprises a host, a first control device, a second control device, and a storage drive that has a physical connector A and a physical connector B for connecting to the first control device and second control device, respectively. When the storage drive is configured to operate in first working mode, it provides a shared storage space to be accessed by both the first control device and the second control device. When the storage drive is configured to operate in a second working mode, it provides a first storage space for access by the first control device and a second storage space for access by the second control device.

    IPC: G06F3/06

    Abstract: A first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied to a storage system that includes an NVMe SSD.
