Linux Employees of Lawrence Livermore National Laboratory have ported Sun's/Oracle's ZFS natively to Linux. Linux already had a ZFS port in userspace via FUSE, since license incompatibilities between the CDDL and GPL prevent ZFS from becoming part of the Linux kernel. This project solves the licensing issue by distributing ZFS as a separate kernel module users will have to download and build for themselves.

One of the ZFS features I think is coolest is L2ARC which let you put a fast SSD as a read/write-cache in front of a pool of slower mechanical disks. The blocks you use most frequently will have a copy on the SSD for quick access. IIRC the cache currently doesn't survive a reboot though (it will start caching from scratch again), but they are working on fixing that.
