Fuzzy fairness controller for NVMe SSDs

Modern NVMe SSDs are widely deployed in diverse domains due to characteristics like high performance, robustness, and energy efficiency. It has been observed that the impact of interference among the concurrently running workloads on their overall response time differs significantly in these devices, which leads to unfairness. Workload intensity is a dominant factor influencing the interference. Prior works use a threshold value to characterize a workload as high-intensity or low-intensity; this type of characterization has drawbacks due to lack of information about the degree of low- or high-intensity.
