NVM Express Flexible Data Placement (FDP) - Architecture and Implementation

Learn about NVM Express® Flexible Data Placement (FDP) in this technical presentation from the Storage Developer Conference 2023, delivered by lead proposal author Mike Allison and John Rudelic. Explore how hosts can optimize user data management to achieve lower Write Amplification Factor (WAF), extend SSD lifespan, enhance performance, and reduce latency. Master key FDP concepts including Placement Identifiers, Reclaim Units, Reclaim Unit Handles, and Reclaim Groups. Discover the process of enabling FDP capabilities, managing Reclaim Unit Handles during namespace creation, and executing I/O writes for user data placement in Reclaim Units. Compare and contrast FDP with other NVM Express placement capabilities, while gaining practical knowledge about avoiding SSD garbage collection through strategic I/O write commands. Delve into the architectural framework of FDP and understand its distinct advantages over ZNS and Streams implementations.
