"ZFS on Linux" ready for wide scale deployment

Quoting lead developer Brian Behlendorf from Lawrence Livermore National Lab (LLNL):

"Today the ZFS on Linux project reached an important milestone with the official 0.6.1 release! Over two years of use by real users has convinced us ZoL is ready for wide scale deployment on everything from desktops to super computers." Read the full announcement

ZFSOnLinux (or ZoL) is a high performance implementation of ZFS as a Kernel module and performance is on par with Solaris (especially on new Hardware).

It is used by the LLNL Sequoia HPC Cluster with 55PB of storage:

The porting of ZFS to Linux has been funded by DOE and did start in 2008. Is it important to understand that ZoL is not currently an unstable beta but the result of a more than 5 year effort.
