Abstract
Modern flash storage provides high performance but suffers from unpredictable latency due to internal parallelism and resource contention. This paper presents IODA, a host/device co-design that provides strong predictability contracts for flash storage arrays.

This paper presents IODA, a comprehensive framework for achieving I/O determinism in flash storage arrays. It provides programming interfaces and system support for predictable I/O performance through host/device co-design.
