Data access method and apparatus, and first computing device

A first computing device comprising:

• a transceiver configured to:
• receive, from a host, a first write operation command for writing to-be-written data into a storage pool coupled to the first computing device through a network interface card;
• and
• receive, from a second computing device, a second write operation command that is based on preprocessing the first write operation command;
• and
• a processor coupled to the transceiver and configured to:
• perform a data processing operation on the to-be-written data according to the second write operation command to obtain processed to-be-written data;
• and
• in response to the data processing operation, enable the network interface card to:
• read the processed to-be-written data;
• write the processed to-be-written data into the storage pool;
• receive, from the storage pool, a write complete command;
• and
• send, to second computing device, the write complete command.

A computer program product comprising instructions that are stored on a computer-readable storage medium, and that when executed by a processor, cause a first computing device to:

• obtain, from a host, a first write operation command for writing to-be-written data into a storage pool coupled to the first computing device through a network interface card;
• receive, from a second computing device, a second write operation command that is based on preprocessing the first write operation command;
• perform a data processing operation on the to-be-written data according to the second write operation command to obtain processed to-be-written data;
• and
• in response to the data processing operation, enable the network interface card to:
• read the processed to-be-written data;
• write the processed to-be-written data into the storage pool;
• receive, from the storage pool, a write complete command;
• and
• send, to second computing device, the write complete command.
