BIZA: Design of Self-Governing Block-Interface ZNS AFA for Endurance and Performance
All-flash array (AFA) has become one of the most popular storage forms in diverse computing domains. While traditional AFA implementations adopt the block interface to seamlessly integrate with most existing software, this interface hinders the host from managing SSD internal tasks explicitly, which results in both short endurance and poor performance. In comparison, ZNS AFA, such as RAIZN, adopts ZNS SSDs and exposes the ZNS interface to the users. This solution attempts to raise the level of responsibility for SSD management. Unfortunately, it faces severe compatibility issues as most upper-layer software only takes block I/O accesses for granted.
