Trever Nightingale has been doing UNIX administration full time for over 10 years for a very wide variety of organizations, from higher education and scientific research environments, to fortune 50 corporations, to mega volume web startups, to defense. His IT career started at Minnesota Public Radio, where he did (among other things) the live webcast for Garrison Keillor's "Prairie Home Companion," including traveling with the show to stream it from Town Hall in NYC. Most recently Trever worked for over three years at the Naval Research Laboratory in Monterey, where he built JAVA web application servers and also work-group-sized HPC Linux clusters for the researchers and developers he supported. His involvement there was all the way up and down the stack, from motherboard firmware, to Infiniband drivers and library stacks, to touching upon code parallelization issues in MPI. His recent work at NERSC has included rebuilding NERSC's web hosting infrastructure and introducing new filesystem technology (ZFS) into our server operations. Trever holds a Bachelor of Arts in Chemistry from Amherst College and a master's degree in Philosophy from the University of Minnesota.
T. Nightingale, No Cost ZFS On Low Cost Hardware, NERSC High Performance Computing Seminar, June 14, 2011,
Today's data generation rates and terabyte hard drives have led to a new breed of commodity servers that have very large filesystems. This talk looks at the implications and describes the decision to deploy ZFS under FreeBSD on NERSC servers. Included will be a look at pertinent ZFS features, configuration decisions adopted, experiences with ZFS so far, and how we are using the features ZFS brings with it to gain some new functionality that was not possible with previous filesystems.
