Jeff Bonwick was a Sun Fellow at Sun Microsystems, later a Vice President at Sun and then a Senior Software Architect at Oracle until his departure from the company on 30 September 2010.[1]
He led the team which developed ZFS for Solaris.[2]
Notable among Bonwick's other work is the slab allocator,[3] an object-caching kernel memory allocator, and the LZJB compression algorithm.
Bonwick published a blog,[4] which details the development of ZFS.
