Abstract: In a data access method, a network device receives access requests sent by a plurality of clients connected to the network device, and sends the access requests to an access queue of a storage unit. The storage unit executes the access requests in the access queue, and returns processing results of the access requests of the plurality of clients. The network device returns the processing results that are of the access requests and that are returned by the storage unit to the clients corresponding to the access requests.

Abstract: A data access method and a related apparatus and system, where the data access method includes receiving, by a non-volatile memory express (NVMe) from a processor, a first key-value command whose format meets an NVMe interface standard, where the first key-value command carries a first operation manner indicator and a first operation object type indicator, and an operation object type indicated by the first operation object type indicator includes a value, obtaining, by the NVMe, N keys corresponding to the first key-value command, and performing, by the NVMe on a value corresponding to each of the N keys, an operation indicated by the first operation manner indicator. Hence, the data access method is helpful in promoting a data access manner in an NVMe technology.

Abstract: A first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied to a storage system that includes an NVMe SSD.

Abstract: A data processing system and method, and a corresponding apparatus, where the data processing system includes a controller and at least two storage nodes. The controller is configured to receive, using a first coupling between the controller and a host, an operation request received from the host, where the operation request includes an identity of target data and an operation type, determine at least one target storage node from the at least two storage nodes according to the identity of the target data, and send an instruction message to the at least one target storage node using a second coupling to the at least one target storage node, where the at least one target storage node is configured to send the target data to the host or obtain the target data from the host according to the instruction message.

Abstract: A data storage method includes that a first device generates N check units for M data units, where M and N are both positive integers, and M+N=K. The first device stores the K units in K hard disk modules in the storage system, where the K units include the M data units and the N check units. Each of the K hard disk modules stores one of the K units. Each hard disk module includes an interface module and a hard disk, and the interface module communicates with the hard disk.
