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 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.
