#202: What is the NVM Express® Flexible Data Placement (FDP) Storage Developer Conference
-
- Technology
This presentation by provides an overview of the NVM Express® ratified technical proposal TP4146 Flexible Data Placement and shows how a host can manage its user data to capitalize on a lower Write Amplification Factor (WAF) by an SSD to extend the life of the device, improve performance, and lower latency. Mike Allison, the lead author of the technical proposal will cover: a) The new terms associated with FDP (e.g., Placement Identifier, Reclaim Unit, Reclaim Unit Handle, Reclaim Groups, etc.); b) Enabling the FDP capability; c) Managing the Reclaim Unit Handles during namespace creation; d) How I/O writes place of the user data to a Reclaim Unit; e) The differences between other placement capabilities supported by NVM Express.
Learning Objectives 1) Obtain an understanding of the architecture of the NVM Express Flexible data placement (FDP) capability; 2) Learn how issue I/O write commands to place user data and avoid SSD garbage collection; 3) Understand the differences between FDP, ZNS, and Streams.
