Introduce the characteristics of ZNS SSDs and current Linux SW ecosystem for ZNS SSDs. Describe an adapter xZTL that enables the host to access ZNS SSDs easily. We adopt xZTL to Percona and benchmark by sysbench. The results show that xZTL improves TPS of ZNS SSD by 14% – 90% and reduces latency (p99) by 19% – 47% compared with conventional SSD of identical hardware.
