Improve Linux swap for High Speed Flash Storage - Shaohua Li, Fusion-io

Sign up or log in to save this event to your list and see who's attending!


Because of high density, low power and low price, flash storage (SSD) is a good candidate to partially replace DRAM. A quick usage model is using SSD as Linux swap. But Linux swap is designed for slow hard disk storage. There are a lot of challenges to efficiently use SSD for swap. This presentation will give details
about these challenges, the mystery behind them, possible solutions and current progress. Some solutions are specific for SSD, so some SSD internals will be discussed too.

This talk involves both Linux swap and SSD optimization. It would be good staff for people who have interesting in these areas. While this is for high speed SSD, actually some contents can be applied to relatively low speed flash storage too (for example, SD card swap in Android phone).
