summary

Describes SetMP, a set-associative mapping-management scheme for SSDs that proactively aggregates I/O requests to increase multi-plane (MP) operations across planes within a die. It targets the plane-level parallelism and long block-open-time issues in multi-plane SSDs by changing when and how aligned-page writes are scheduled, and reports a 16.9% average I/O latency reduction compared to prior optimizations without substantially increasing block open time.
