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: This application discloses a data access method applied to a first storage node in a storage system. The 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 a storage system that includes an NVMe SSD.

Abstract: A data processing method and a storage apparatus are disclosed. The data processing method includes: receiving, by a non-volatile memory express (NVMe) storage device, an NVMe write command sent by a host, where the NVMe write command carries a key and a value pointer, the value pointer points to first storage space, and the first storage space is used to store a value; obtaining, by the NVMe storage device, the key from the NVMe write command and a value length, and allocating second storage space to the value according to the value length, where the second storage space is in the NVMe storage device; and obtaining, by the NVMe storage device, the value from the host, and storing the value in the second storage space.
