    Abstract: A data reading method, apparatus, and system, and a distributed system, related to the field of storage technologies and can be applied to data reading. The method includes: receiving a data read request sent by a terminal, where the data read request includes a logical address of target data; locally searching, based on the logical address, a first slave node for a latest version of the target data; and, when it is determined that the latest version of the target data has been stored in each of a plurality of slave nodes, sending the latest version of the target data to the terminal. This data reading method, apparatus, system, and distributed system can avoid a rollback of a version of read data.

    IPC: G06F12/02

    Abstract: In a data read/write method, a storage server receives a write request of a client and performs storage. Each write request carries a to-be-written slice, an ID of a first storage device, and a virtual storage address of a first virtual storage block. If storage is performed continuously successfully from a start address within virtual storage space of a virtual storage block in the storage device, a successful continuous storage address range is recorded. For each storage device, all data within the successful continuous storage address range is successfully stored data. When receiving a read request of a client for an address segment within the address range, the storage server may directly return data that needs to be read to the client.

    Abstract: A method, an apparatus, and a system for calculating a identification threshold to distinguish cold data and hot data. The method includes: obtaining, according to a total capacity of hot data storage mediums, a size of data blocks, and the IO count statistical values on all the storage nodes and when the hot data storage mediums are filled with the data blocks corresponding to large IO count statistical values, a minimum IO count value in a count range corresponding to a minimum IO count statistical value in the large IO count statistical value, and using the minimum IO count value as a identification threshold to distinguish cold data and hot data. In the present invention, all storage nodes in a storage system, independently but cooperatively, implement hierarchical data storage in the entire storage system.

    Abstract: A beamforming method and apparatus are disclosed, to expand coverage of a PDCCH in a particular direction, and improve demodulation performance of the PDCCH. Under this method, a cell-specific reference signal CRS wide beam can be combined by a base station with N CRS narrow beams to form N CRS composite beams. A first beam can be selected by the base station from the N CRS composite beams. Beamforming processing can be performed by the base station on a physical downlink control channel (PDCCH) based on a weight of the first beam to form a second beam. The first beam and the second beam can be sent.
