Jeff Bonwick invented and led development of the ZFS file system,[1] which was used in Oracle Corporation's ZFS storage products as well as startups including Nexenta, Delphix, Joyent, and Datto, Inc.[2][3] Bonwick is also the inventor of slab allocation,[4] which is used in many operating systems including MacOS and Linux, and the LZJB compression algorithm.
[8] In 2010 Bonwick co-founded a small company called DSSD with Mike Shapiro and Bill Moore, and became chief technical officer.
He developed DSSD's whole-system simulator, which enabled the team to explore possible hardware topologies and software algorithms.
By the end of 2016, Bill Moore had left the company, while Bonwick remained as CTO.
[14] The name LZJB is derived from its parent algorithm and its creator — Lempel Ziv Jeff Bonwick.
