Abstract: A file management method, a distributed storage system, and a management node are disclosed. In the distributed storage system, after receiving a file creation request sent by a host for requesting to create a file in a distributed storage system, a management node allocates, to the file, first virtual space from global virtual address space of the distributed storage system, where local virtual address space of each storage node in the distributed storage system is corresponding to a part of the global virtual address space. Then, the management node records metadata of the file, where the metadata of the file includes information about the first virtual space, and the information about the first virtual space is used to point to local virtual address space of a storage node that is used to store the file. Further, the management node sends, the information about the first virtual space to the host.

Abstract: Embodiments of this application provide a storage component, a preparation method, a reading/writing method, a storage chip, and an electronic device, is related to the storage technology field, and is used to resolve a problem that a quantity of storage states of a spin orbit torque-magnetic random access memory is increased while a storage state change range remains unchanged. The storage component includes: a first magnetic tunnel junction, a spin orbit coupling layer and a second magnetic tunnel junction that are sequentially arranged in a stacked manner. The first magnetic tunnel junction includes a first free layer, and the second magnetic tunnel junction includes a second free layer. The first free layer and the second free layer are arranged on two opposite surfaces of the spin orbit coupling layer.

Abstract: A device suspension method and a computing device are provided. In the method, before a device enters a suspended state, memory space occupied by a background process that is unrelated to a foreground process is released. In this way, the background process unrelated to the foreground process is not saved in a memory of the device. In other words, it reduces data stored in the memory when the device is suspended. Therefore, when the device needs to be woken up, only a relatively small amount of data needs to be read from the memory, and a working state can be rapidly restored. This can reduce a delay of reading data from the memory when the device is woken up, thereby accelerating a wakeup speed of the device. In addition, the data is stored in the memory when the device is suspended.

Abstract: A hybrid storage device includes a controller, a volatile storage unit, and a non-volatile storage unit. When the hybrid storage device is in a first working mode, the volatile storage unit is in an enabled state, and the non-volatile storage unit is in a disabled state; when the hybrid storage device is in a second working mode, the non-volatile storage unit is in an enabled state, and the volatile storage unit is in a disabled state. When the hybrid storage device runs in the first working mode, and when detecting that a running parameter of the computer meets a first switching condition, the controller enables the non-volatile storage unit, copies data in the volatile storage unit to the non-volatile storage unit, and switches the hybrid storage device to the second working mode.

Abstract: An electronic device includes a processor, a volatile memory, and a non-volatile memory. The non-volatile memory stores a first operating system, and the electronic device works in a first working mode and a second working mode. When the electronic device is in the first working mode, a second operating system is run in the volatile memory. When the processor detects that the electronic device reaches a preset condition for entering the second working mode, the non-volatile memory is enabled, and non-system data in the volatile memory is moved to the non-volatile memory. The non-system data does not include the second operating system. After the movement of the non-system data is completed, the volatile memory is disabled, and the first operating system is run in the non-volatile memory, so that the electronic device enters the second working mode.
