Who are we?
I am Oliver Gould
, a System
Administrator and student at Stevens Institute
in Hoboken, NJ. Google
is giving me a Summer of Code
port ZFS to NetBSD
during the summer of
Dieter Baron will be mentoring me through this project with Jason Thorpe,
Matthias Scheler, Brett Lymn, and, of course, the NetBSD, FreeBSD, and
What is it?
Sun Microsystem's Zettabyte Filesystem (ZFS), since Nov 2005, has
proven to be a major breakthrough in filesystem technology, supporting
features such as disk pools, snapshots, 'unlimited' scalability, and
various other performance improvements over prior art. Such
advancements will make ZFS a major force in industry in coming years.
A BSD-licensed implementation of ZFS is utterly impractical within the
constraints of Google's Summer of Code (SoC). However, porting the
CDDL'd ZFS implementation present in OpenSolaris is feasible. In
particular, Pawel Jakub Dawidek has been able to port a significant
portion of ZFS to FreeBSD. His work provides a good basis for porting
ZFS to NetBSD.
Furthermore, OpenSolaris has published a high-level roadmap for
porting ZFS to other platforms. This outlines a path for success,
which I shall follow.
