Please stop with the FUD... 'long time ago'? No elaboration on what 
implementation/platform you 'played with'?

With a proper implementation, ZFS is an excellent, mature, reliable 
option for storage... maybe not quite the fastest/highest performing 
screaming speed demon, but enterprises are concerned with more than just 
raw performance - in fact, data integrity tops the list.



Yes, the LINUX version has a long way to go (due to stupid licensing 
restrictions it must be rewritten from scratch to get into the kernel), 
but personally I'm chomping at the bit for BTRFS, which looks like it is 
coming closer to usability for production systems (just got a basic fsck 
tool which now just needs to be perfected).


Best regards,
