Описание: Building on the momentum of Live Migration and Flexible Data Placement, NVM Express® (NVMe®) is ratifying TP4176 Quality of Service for PCIe Bandwidth and IOPS for a Controller. However, implementing this standard in real-world SSDs can be complex. This presentation will provide clarity on the standardized modes for QoS control, including key parameters and simplified control knobs. Through example use cases and scenarios, we will explore reasonable settings for meeting customer requirements, as well as situations where "best effort" approaches may be necessary. This presentation by Dan Helmick of Samsung aims to initiate a conversation on intelligent QoS parameter setting on the host side, with a focus on achieving specific goals and exploring the potential for consistency across SSD vendors and generations.
