Abstract

With Flexible Data Placement (FDP) from NVM Express® (NVMe) finalized and increasing in ecosystem momentum, it has become clear that implementation choices are becoming a real differentiator among FDP drive configurations. Some customers leverage years of Multi-Streams deployment to migrate onto large RU sizes within a single RG. Some customers may be eager to mirror their experience with Open Channel SSDs by requesting small RGs and RU sizes. Yet another customer base might be examining FDP from a history of working with high Zone counts translating into large RUH counts. This presentation will provide customers with some high level guidance and background while engaging with SSD vendors. By understanding the drive impacts of such FDP configuration choices, customers and vendors can arrive at the best system solution for varying use-cases.

Learning Objectives

Upon completion, participant will be able to describe the impact of Garbage Collection implementation choices in the SSD on system WAF and Host experience.
Upon completion, participant will be able to understand the Host SW architecture and system impacts on FDP SSDs with many RGs, differing RU counts, and different RU sizes.
Upon completion, participant will be able to refine Host SW architecture and customer requirements to best suit their storage objectives.
