    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 server management method and a server, where the server is divided into two parts, a computing component and a storage component, according to a part maintenance cycle. The computing component and the storage component are connected in a detachable manner. The computing component includes a part with a short maintenance cycle, and the storage component includes a part with a long maintenance cycle. Therefore, the computing component or the storage component can be flexibly replaced during server maintenance, and maintenance efficiency is high.

    Abstract: A method, device, and system for implementing hardware acceleration processing, where the method includes memory mapping input/output (MMIO) processing being performed on a data buffer address of a hardware acceleration processor in order to obtain an address in addressing space of a central processing unit (CPU). In addition, a network adapter has a remote direct memory access (RDMA) or a direct memory access (DMA) function. Alternatively, a network adapter of a hardware acceleration device can directly send received data on which the hardware acceleration processing is to be performed to a hardware acceleration processor. In this way, resource consumption is reduced when the CPU of a computer device receives and forwards the data on which the hardware acceleration processing is to be performed, and in addition, storage space of a memory of the computer device is saved.

    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.
