Abstract: A magnetic storage track and a magnetic memory are provided. The magnetic storage track includes multiple stacked storage track units. A transition layer is disposed between two neighboring storage track units. The transition layer is constituted by a semiconductor material deposited on an insulating material, and includes a gating circuit and a read/write apparatus. Because the magnetic storage track includes multiple stacked storage track units, a track length of the magnetic storage track is constituted by track lengths of the multiple storage track units. Therefore, when a storage capability of the magnetic storage track needs to be improved, the track length of the magnetic storage track may be increased by adding the storage track unit.

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: 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.
