History
In 2010 Bonwick co-founded a small company called DSSD with Mike Shapiro and Bill Moore, and became chief technical officer.{{Cite news |title= Meet DSSD, Andy Bechtolsheim's secret chip startup for big data |date= April 4, 2013 |work= Giga Om |author= Stacey Higginbotham |url= http://gigaom.com/2013/04/04/meet-dssd-andy-bechtolsheims-secret-chip-startup-for-big-data/ |access-date= March 4, 2017 }} 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.{{cite web|last1=Harris|first1=Robin|title=What is DSSD Building?|url=http://storagemojo.com/2013/03/13/what-is-dssd-building/|website=StorageMojo|publisher=TechnoQWAN LLC|access-date=27 July 2016}} DSSD was acquired by EMC Corporation in 2014,{{Cite news |title= EMC acquires flash storage startup DSSD |author= Sephen Lawson |date= May 5, 2014 |work= Computer World |url= http://www.computerworld.com/article/2489005/data-center/emc-acquires-flash-storage-startup-dssd.html |access-date= March 4, 2017 }} 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.{{Cite news |title= DSSD President quits Dell EMC |author= Chris Mellor |date= December 9, 2016 |work= The Register |url= https://www.theregister.co.uk/2016/12/09/dssd_president_quits_dell_emc/ |access-date= March 4, 2017 }} The DSSD product, called D5, was cancelled in March 2017.{{Cite news |title= Dell kills off standalone DSSD D5, scatters remains into other gear: Blueprints and staff shifted to different projects after EMC spent '$1bn' on tech |author= Chris Mellor |date= March 2, 2017 |work= The Register |url= https://www.theregister.co.uk/2017/03/02/dell_cans_standalone_dssd/ |access-date= March 4, 2017 }}
LZJB
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.{{Cite journal|author=Y. Rathore, M. Ahirwar, R. Pandey|title=A Brief Study of Data Compression Algorithms|url=https://www.academia.edu/11814232|journal=Journal of Computer Science IJCSIS|year=2013|volume=11|issue=10|pages=90}} The name LZJB is derived from its parent algorithm and its creator — Lempel Ziv Jeff Bonwick.
