when OpenSolaris was released it seemed like a nice thing for all those Solaris admins who wanted a shiny new free version to play with, but not so relevant to folks with actual work to do. Zettabyte filesystem, however, changed the landscape. Officially it's just ZFS now, not Zettabyte. But zettabyte is more fun to say. At any rate, ZFS is very impressive and represents a huge leap past other filesystems on the market. You know, all those filesystem utilities you've been relying on all these years? All that fsck, dump, restore, mkfs, tunefs, and their Ext3/JFS/XFS/ReiserFS/UFS counterparts; volume managers like EVM and LVM; raidtools; rysnc; quota; fdisk, and all the rest of the baggage you've been forced to lug around just to coax filesystems into a semblance of usefulness - using ZFS means you can dump them all. ZFS was written from the ground up to meet modern needs.
