    Abstract: A cabinet server and a data center where the cabinet server includes multiple function node layers vertically arranged to form a server core and multiple intra-cabinet antennas vertically arranged and disposed at one side of the server core, an intra-cabinet antenna is wirelessly connected to adjacent intra-cabinet antennas. A transmission path is formed of the vertically arranged intra-cabinet antennas when a radio signal is transmitted within the cabinet server. Since the intra-cabinet antennas are disposed at the side of the server core, electromagnetic radiation generated by the radio signal in a transmission process has a relatively small effect on the function nodes, thereby reducing the effect of the electromagnetic radiation on various electronic devices in the function nodes, improving service lives of the electronic devices, and improving transmission quality of the radio signal.

    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: An information storage apparatus includes a magnetic track, a writer, and a reader, where the magnetic track includes a number of magnetic domains. Each magnetic domain is divided into at least two magnetic regions, and the writer is disposed on the magnetic track, and configured to write information to the at least two magnetic regions of each magnetic domain. The reader, disposed on the magnetic track, is configured to read the written information from the at least two magnetic regions. Therefore, multiple pieces of valid information are written to one magnetic domain of the magnetic track, thereby increasing storage density of the magnetic track, and expanding a storage capacity of the storage apparatus.

    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.
