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 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.

Abstract: A storage system comprises 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. The physical connector A and physical connector B are independent access ports. The first control device is configured to access the storage drive through the physical connector A, and the second control device is configured to access the storage drive through the physical connector B.

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 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.

Abstract: A just a bunch of flash solid-state drive cluster (JBOF) and a method for transmitting a data processing request include obtaining a data processing request sent by a storage controller, determining a type of the data processing request, and either forwarding the data processing request to the target solid state drive (SSD) when the type of the data processing request is a bypass type, or sending the data processing request to a computing unit in the JBOF and sending the data processing request processed by the computing unit to the target SSD when the type of the data processing request is a background computing type.
