There is far more too it than has been made public, and all the conjecture in the world isn't likely to clear it up for us. If you post a link to one side of the story, you should at least post a link to the other side. Here's a couple updates from Sun's legal counsel. Oct 2008: http://www.sun.com/lawsuit/zfs/ Jun 2008: http://blogs.sun.com/dillon/entry/netapp_draft Oct 2008: http://blogs.sun.com/dillon/entry/more_on_the_netapp_litigation Oct 2008: http://blogs.netapp.com/dave/2008/10/current-status.html It appears that Sun is besting NetApp. Sun has gotten numerous NetApp patent claims invalidated, including all claims for one of NetApp's self described 'core' patents. Sun has also had a few of its patent claims dismissed, but they have a larger arsenal which which they are countersuing. If I were to put some skin in the game, I'd put money on Sun. But what about Apple? Apple needs a next generation file system, and they need it last year. Or 2-3 years ago. Hence Apple's interest in ZFS. But the case is already 2 years old and Sun is filing motions to stay the suit for even longer, giving the US PTO office time to review and invalidate even more patent claims. If Apple committed to and deployed ZFS, they could easily be on the hook for many millions of dollars in licensing fees down the road. It could end up costing them far more than building a next generation FS for Mac OS X in house. And what about FreeBSD? This is what MLP had to say at http://blogs.sun.com/jonathan/entry/harvesting_from_a_troll > First, the basics. Sun indemnifies all its customers against IP > claims like this.
