Flash devices introduced a sudden shift in the performance profile of direct attached storage. With IOPS rates orders of magnitude higher than rotating storage, it became clear that Linux needed a re-design of its storage stack to properly support and get the most out...
Understanding how Linux kernel IO subsystem works is a key to analysis of a wide variety of issues occurring when running a Linux system. This talk is aimed at helping Linux users understand what is going on and how to get more insight into what is happening. First we...
Storage keeps moving forward, and so does the Linux IO stack. This talk will detail some of the recent additions and changes that have gone into the Linux kernel storage stack, helping Linux get the most out of industry innovations in that...
Since the dawn of time, Linux has had to make do with inferior IO interfaces. Native Linux AIO supports only a niche application class (O_DIRECT), and even for that use case, it’s far too slow for modern storage. This talk will detail io_uring, a modern IO interface...
A review about what’s new with io_uring. Faster IO with a consistent...
