Ben Rockwood is awesome. If you haven’t had a chance to check out his blog, its a must read for any Solaris Admin.
He gave a presentation at the Open Storage Summit about ZFS. (Video Here)Its worth the read / view for some indepth ZFS concepts.
Joerg assisted in turningsome of this into plain English so the rest of us can understand.
Kudos to Ben for giving props to Matty in the pdf!
