One Line Summary
Introduction to Open-Channels SSDs and LightNVM. It will show the possibilities of this new storage interface, report on the current status of LightNVM, and present the development roadmap.
This presentation gives an introduction to Open-Channels SSDs and LightNVM – the kernel subsystem creating support for Open-Channel SSDs. Open-Channel SSDs allow applications to directly control internals of an SSD, thereby controlling data placement and garbage collection within the SSD. The benefits are consistent latency and throughput in high-performance workloads and extending its lifetime. The main objective of this talk is show the possibilities of this new storage interface, report on the current status of LightNVM, and present the development roadmap for both upcoming kernel functionality and user space support.
Matias Bjørling obtained a Ph.D. in operating systems and characteritics of solid state drives. He is a member of CNEX Labs technical staff. Prior to that, he worked on performance characterization of flash-based SSDs, operating- and database systems research and the multi-queue block layer. Matias is a contributor to the Linux Kernel and is the creator of the LightNVM framework for Open-Channel SSDs.
