Huawei OceanStor 9000 uses the erasure code technology to protect data. A site has six nodes, and the customer requires that data can be restored if three of the disks where a stripe is distributed are faulty. The redundancy level 4+3:1 means that data is striped across four disks and protected by three parity disks. The redundancy level 6+3 means that data is striped across six disks and protected by three parity disks. Both of these redundancy levels can be used to meet the customer's requirement.
