Host Workloads Achieving WAF==1 in an FDP SSD
Flexible Data Placement (FDP) is a new NVM Express® (NVMe) feature that advertises the ability to achieve Write Amplification Factor (WAF) of 1. This presentation will describe what a WAF of 1 means for an SSD. Several example workloads achieving a WAF of 1 will be discussed. Additionally, some Hosts have an increased ability to restrict either the deallocate behavior or the write behavior of their various workloads. For this reason, a review of different Host side rule implementations will be discussed.
