processing, based on the write operation command, the to-be-written data to obtain first processed data; and writing the first processed data into the storage pool. ### Claim 2 (depends on 1) The method of claim 1, wherein processing the to-be-written data comprises performing erasure coding (EC), data integrity field (DIF) protection, encryption on the to-be-written data, or decryption on the to-be-written data. ### Claim 3 (depends on 1) The method of claim 1, wherein the first processed data comprises a verification data block of the to-be-written data, and wherein writing the first processed data comprises storing the verification data block in the storage pool. ### Claim 4 (depends on 3) The method of claim 3, wherein writing the first processed data further comprises storing, the verification data block in a memory of the network adapter. ### Claim 5 (depends on 3) The method of claim 3, wherein the first processed data further comprises the to-be-written data, and wherein before processing the to-be-written data, the method further comprises storing the to-be-written data in a memory of the network adapter. ### Claim 6 (depends on 5) The method of claim 5, wherein writing the first processed data comprises storing the to-be-written data from the memory into the storage pool. ### Claim 7 (depends on 1) The method of claim 1, wherein the first processed data comprises the to-be-written data and data integrity field (DIF) protection data, or wherein the first processed data comprises data based on encryption of the to-be-written data. ### Claim 8 (depends on 1) The method of claim 1, further comprising: receiving, from the host, a read operation command to read data from the storage pool; reading, based on the read operation command, the data from the storage pool to obtain read data; processing the read data to obtain second processed data; and sending, to the host, the second processed data. ### Claim 9 (depends on 8) The method of claim 8, wherein processing the read data comprises performing decryption processing on the read data. ### Claim 10 A network adapter, comprising: a transceiver configured to receive, from a host, a write operation command to write to-be-written data into a storage pool; and at least one processor coupled to the transceiver and configured to: process, based on the write operation command, the to-be-written data to obtain first processed data; and write the first processed data into the storage pool. ### Claim 11 (depends on 10) The network adapter of claim 10, wherein the at least one processor is further configured to process the to-be-written data by performing erasure coding (EC), data integrity field (DIF) protection, encryption on the to-be-written data, or decryption on the to-be-written data. ### Claim 12 (depends on 10) The network adapter of claim 10, wherein the first processed data comprises a verification data block of the to-be-written data, and wherein the at least one processor is further configured to write the first processed data by storing the verification data block in the storage pool. ### Claim 13 (depends on 12) The network adapter of claim 12, wherein the at least one processor is further configured to store the verification data block in a memory of the network adapter. ### Claim 14 (depends on 12) The network adapter of claim 12, wherein the first processed data further comprises the to-be-written data, and wherein before processing the to-be-written data, the at least one processor is further configured to store the to-be-written data in a memory of the network adapter. ### Claim 15 (depends on 14) The network adapter of claim 14, wherein the at least one processor is further configured to write the first processed data by storing the to-be-written data from the memory into the storage pool. ### Claim 16 (depends on 10) The network adapter of claim 10, wherein the first processed data comprises the to-be-written data and data integrity field (DIF) protection data, or wherein the first processed data comprises data based on encryption of the to-be-written data. ### Claim 17 (depends on 10) The network adapter of claim 10, wherein the transceiver is further configured to receive, from the host, a read operation command to read data from the storage pool, and wherein the at least one processor is further configured to: read, based on the read operation command, the data from the storage pool to obtain read data; process the read data to obtain second processed data; and send the second processed data to the host. ### Claim 18 (depends on 17) The network adapter of claim 17, wherein the at least one processor is further configured to perform decryption processing on the read data. ### Claim 19 A computer program product comprising instructions that are stored on a computer-readable storage medium, and that when executed by at least one processor, cause a network adapter to: receive, from a host, a write operation command to write to-be-written data into a storage pool; process, based on the write operation command, the to-be-written data to obtain first processed data; and write the first processed data into the storage pool. ### Claim 20 (depends on 19) The computer program product of claim 19, wherein the instructions further cause the network adapter to process the to-be-written data by performing erasure coding (EC), data integrity field (DIF) protection, encryption on the to-be-written data, or decryption on the to-be-written data.
