multi-level fault tolerance to ensure the best balance of reliability, security and redundancy Adopt a multi-level fault-tolerant design, focusing on multi-copy fault tolerance with high redundancy, supplemented by erasure code fault tolerance with low redundancy.

At the same time, based on the volume and application characteristics of each data, large-volume data uses erasure coding for fault tolerance, and small-volume data uses multi-copy fault tolerance.
