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.

His roles included Sun Fellow , ^{[5] [6]} Sun Storage CTO, ^[7] and Oracle vice president. ^[8]

History [ edit ]

In 2010 Bonwick co-founded a small company called DSSD with Mike Shapiro and Bill Moore, and became chief technical officer. ^[9] He co-invented DSSD's system hardware architecture and software. He developed DSSD's whole-system simulator, which enabled the team to explore possible hardware topologies and software algorithms. ^[10] DSSD was acquired by EMC Corporation in 2014, ^[11] which then became part of Dell Technologies in 2016. By the end of 2016, Bill Moore had left the company, while Bonwick remained as CTO. ^[12] The DSSD product, called D5, was cancelled in March 2017. ^[13]

LZJB [ edit ]

Bonwick invented LZJB, a lossless data compression algorithm to compress crash dumps and data in ZFS . The software is CDDL license licensed . It includes a number of improvements to the LZRW1 algorithm, a member of the Lempel?Ziv family of compression algorithms. ^[14] The name LZJB is derived from its parent algorithm and its creator ? Lempel Ziv Jeff Bonwick.
