Abstract: A data access method implemented by a first computing device includes receiving a second write operation command sent by a second computing device, where the second write operation command is obtained after the second computing device preprocesses a first write operation command generated by a host, and the first write operation command is used to write to-be-written data into a storage pool, and performing a data processing operation on the to-be-written data according to the second write operation command, wherein the first computing device writes processed to-be-written data into the storage pool.

Abstract: A data processing method and system, where the method includes: receiving, by a non-volatile memory express (NVMe) controller, a first Peripheral Component Interconnect express (PCIe) packet sent by a host, where a memory in the NVMe controller is provided with at least one input/output (I/O) submission queue, and the first PCIe packet includes entrance information of a target I/O submission queue and at least one submission queue entry (SQE); and storing the at least one SQE in the target I/O submission queue based on the entrance information of the target I/O submission queue. Therefore, an NVMe data processing process is simplified and less time-consuming, and data processing efficiency is improved.
