ZFS in OSX

According to World of Apple, the next release of OSX (Leopard) contains Sun’s ZFS. If you haven’t heard of ZFS, you should really check it out. Sun is calling it “The last word in file systems”, and they may be right. Maximum filesystem sizes in the zettabyte range, maximum file sizes in the exabyte range, built-in checksumming to guarantee filesystem integrity. Simple storage pools for creating filesystems without a separate volume manager. Self-healing. Blazingly fast. Dynamic striping. Automatic block size adjustment. Snapshots. It’s all there and then some. Think of it as being able to treat your local storage like an enterprise SAN. I’m pretty excited about this (if you can’t tell). I wonder if Apple will let me put my root filesystem on ZFS…
