The Promise of NVMe Flexible Data Placement in Data Center Sustainability
By 2040, data centers could account for up to ~14% of all carbon emissions worldwide. Flash SSDs contribute to data center carbon emissions due to their limited endurance. The common practice of over-provisioning Flash SSDs to control write amplification, improve lifetime and optimize for total cost of ownership of data centers is inefficient and contributes to the carbon footprint. Considering the increased focus on data center climate impact and net-zero carbon goals, improving Flash SSD lifetime and utilization are key to reducing carbon emissions. Targeted data placement on SSDs is known to reduce write amplification and improve lifetime. The latest data placement technology - NVMe Flexible Data Placement (FDP), shows great promise in reducing carbon emissions with minimal engineering effort. Providing control to applications to place their data with NVMe FDP results in more informed data placement strategies with minimal modifications to the application stack. Consequently, this leads to reduced SSD write amplification and enables better utilization. In this talk, we explore NVMe FDP’s future in Data Center Sustainability by showcasing its ability to reduce embodied (endurance) and operational (power) carbon emissions for systems at scale. We use several example workloads and CacheLib - a deployed system at scale, to illustrate the impact and reduction in carbon emissions with NVMe FDP.
