    Abstract: According to the method for determining a redundant array of independent disks provided in the present invention, for an actual physical disk including n disk groups in which each disk group includes m disks, the n disk groups include m2*(m*n) logical blocks, and a logical block matrix corresponding to m distributed RAIDs can be generated. Therefore, a correspondence between the actual physical disk and the distributed RAIDs can be obtained. In a scenario of data storage or the like, a mapping relationship table of the physical disk and the RAIDs does not need to be stored, thereby saving storage space of a system, reducing maintenance costs, and improving reliability of the system.

    Abstract: The technology of this application relates to a packet processing method, a gateway device, and a storage system, and belongs to the field of storage technologies. In this disclosure, a request for accessing a non-volatile memory express (NVMe) node is converted into a request for accessing a remote direct memory access (RDMA) node. Because a storage medium of the NVMe node is a hard disk, and a storage medium of the RDMA node is a memory, the memory can provide a faster read/write speed than the hard disk. Therefore, storage performance is improved. In addition, this helps a conventional NVMe over fabrics (NOF) storage system expand an RDMA memory pool, and improves flexibility of networking and capacity expansion of the storage system.
