Ding Yuan will be presenting The Design and Implementation of a Log-Structured File System ( by Mendel Rosenblum and John K. Ousterhout.

This paper presents the design of log-structured file system, a novel and unconventional file system design at the time when it was published. NetApp's WAFL file system is later designed as log-structured; but perhaps the paper's biggest impact is in the use of Solid State Drive (SSD): today there is a log-structured file system in every SSD.
