Paper Title: Introduction to Open-Channel SSDs

Paper Abstract: The talk covers (i) the characteristics of open-channel SSD management, (ii) introduces the new open-channel 2.0 specification, (iii) provides background on LightNVM, the Linux subsystem that we designed and implemented for open-channel SSD management, and at last, we show the effectiveness of open-channel SSDs against state-of-art block-based SSDs.
