Abstract: A converged system includes a computing node and a storage node. The computing node is connected to the storage node through a network to build a storage-computing decoupled architecture. A storage medium of the computing node and a storage medium of the storage node form a global memory pool through unified addressing, namely, a global storage medium shared by the computing node and the storage node. When a read/write operation is performed in the system, processing request data is obtained, and a memory operation of the processing request data is performed on the global memory pool based on a memory operation instruction.

Abstract: A method for a source storage device replicating data to a backup storage device, where the source storage device identifies a current fingerprint set based on an identifier of a current backup period. Each of the plurality of fingerprint sets corresponds to a backup period. The current fingerprint set includes one or more fingerprints and identifies one or more data blocks respectively. The one or more data blocks are received by the source storage device between an end moment of a previous backup period and a start moment of the current backup period. Further, the source storage device obtains the one or more data block and sends them the backup storage device. Therefore, data backup efficiency can be improved.

Abstract: Example methods and network devices for order-preserving execution of a write request are disclosed. One example method is performed by a network device of a storage node. The example method includes receiving an order-preserving confirmation request, where the order-preserving confirmation request carries a first write address assigned for a first write request. It is confirmed that execution of a second write request for which a second write address has been assigned is not completed, where the second write address precedes the first write address. Sending feedback information for the order-preserving confirmation request is delayed.

Abstract: A data deduplication method and apparatus are provided. The method includes receiving an overwrite request sent by an external device, where the overwrite request carries a data block and a first address into which the data block is to be stored; determining whether an overwrite quantity of the first address exceeds a first threshold within a time period [t1, t2], where both t1 and t2 are time points, and t2 is later than t1; and when the overwrite quantity of the first address exceeds the first threshold within the time period [t1, t2], skipping performing a deduplication operation on the data block; or when the overwrite quantity of the first address does not exceed the first threshold within the time period [t1, t2], performing a deduplication operation on the data block. Therefore, a large quantity of computing resources of a storage server are saved, and impact brought by a deduplication operation on storage server performance is also decreased.

Abstract: A computer system includes a computing node, a storage node, and an intermediate device. A service runs in the computing node. The storage node stores data of the service. The service is provided with a storage space, and the service performs an operation on the data of the service in the storage node by accessing the storage space. The intermediate device manages the metadata of the storage space, and implements a data operation between the computing node and the storage node based on the metadata of the storage space.

Abstract: In embodiments of the present invention, when a duplicate data query is performed on a received data stream, a first physical node which corresponds to each first sketch value and is in a cluster system is identified according to a first sketch value representing the data stream, and then the first sketch value representing the data stream is sent to the identified physical node for the duplicate data query, and a procedure of the duplicate data query does not change with an increase of the number of nodes in the cluster system; therefore, a calculation amount of each node does not increase with an increase of the number of nodes in the cluster system.
