I/O deduplication is a key technique for improving storage systems' space and I/O efficiency. Among various deduplication techniques content-defined chunking (CDC) based deduplication is the most desired one for its high deduplication ratio. However, CDC is compute-intensive and time-consuming, and has been recognized as a major performance bottleneck of the CDC-based deduplication system.
