Large Block I/O for Linux

Explore the evolution and future of block I/O in Linux with this informative conference talk. Delve into the historical context of 512-byte sector sizes and how the Linux storage stack was designed around this standard. Learn about the challenges posed by increasing device sizes and the shift towards larger sector sizes, such as 4K bytes in modern NVMe devices. Discover the limitations of current page sizes in Linux and the potential benefits of moving to even larger sector sizes, especially for high-capacity devices. Gain insights into ongoing developments for implementing large block sizes in Linux, understand the advantages of this approach, and witness a demonstration of a system utilizing large block sizes. This presentation provides valuable knowledge for those interested in Linux storage optimization and the future of block I/O management.
