History

[edit]

In 2010 Bonwick co-founded a small company called DSSD withMike Shapiroand 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 byEMC Corporationin 2014,[11]which then became part ofDell Technologiesin 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, alossless data compressionalgorithm to compresscrash dumpsand data inZFS.The software isCDDLlicense licensed.It includes a number of improvements to theLZRW1algorithm, a member of theLempel–Zivfamily of compression algorithms.[14]The name LZJB is derived from its parent algorithm and its creator — Lempel Ziv Jeff Bonwick.
