Data processing method and apparatus

A client, comprising:

• at least one processor;
• a network interface card configured to communicate with the at least one processor;
• and
• a first memory, the first memory stores a computer program, that when executed by the at least one processor, causes the client to perform operations comprising:
• generating, by the at least one processor or the network interface card, a first copy of data and a second copy of the data;
• and
• writing, by the network interface card, the first copy of the data into a first address in a second memory of a storage device and the second copy of the data into a second address in the second memory in a one-time unilateral remote direct memory access (RDMA) manner.

A storage device, comprising:

• at least one processor;
• a network interface card;
• and
• a memory, the memory stores a computer program, that when executed by the at least one processor, causes the storage device to perform operations comprising:
• receiving, by the network interface card, a unilateral remote direct memory access (RDMA) write request sent by a client, wherein the unilateral RDMA write request comprises a first copy of data and a second copy of data, a first address corresponding to the first copy of the data in the memory of the storage device, and a second address corresponding to the second copy of the data in the memory;
• and
• writing, by the network interface card, the first copy of the data into the first address and the second copy of the data into the second address according to the unilateral RDMA write request.
