In Huawei OceanStor 9000, the CA that processes write requests divides data into strips based on the protection level and writes data strips into non-volatile dual in-line memory modules (NVDIMMs) if the corresponding nodes. Then these nodes calculate and write parity strips into their NVDIMMs. After all these nodes have successfully written parity strips, the write operation is successful.
