Abstract: WAFL is a high-performance, enterprise file system running on over 250,000 customer systems. With increasing core counts on high-end storage servers, WAFL must continue to scale performance in order to remain competitive. This presentation gives an overview of the WAFL file system and then describes the evolution of WAFL’s core multiprocessor software architecture that has allowed for CPU scaling without requiring a major operating system rewrite. This work was published in OSDI 2016, the premier academic conference on operating systems.
