Abstract: A central node of the system is connected to a working node through a network device. The central node generates a plurality of tasks based on a query request input by a user. When allocating execution devices to the plurality of tasks, the central node configures execution devices of some tasks as the network device, configures execution devices of some tasks as the working node, and then sends configuration instructions to the configured network device and working node, to set, on the network device and the working node, tasks configured for the network device and working node. After configuration is completed, the network device executes the set tasks on the data that passes through the network device.

Abstract: In a solution for accessing a storage system, a client sends, based on an obtained start address that is of a queue of an NVMe storage device and to which an access request points and an obtained logical address that is of the NVMe storage device and to which the access request points, a remote direct memory access command to a storage node in which the NVMe storage device is located.

Abstract: In a method for accessing a storage system, a client in the storage system identifies a logical address of a storage device, and queries a management server regarding a mapping between the storage device and a start address of a submission queue (SQ) in the memory of the storage node. The client then sends an access request including the logical address of the storage device directed to the start address of the SQ to a network interface card NIC of the storage node. The NIC receives and sends the access request to the start address of the SQ in the memory. The storage device obtains the access request from the start address of the SQ and executes the access request.
