I know little about QFS, other than hearing about some of its problems. However, I think it's safe to say that they are entirely different. Right now if you need to have multiple writers on a SAN, you'd have to use QFS. I'm hoping that eventually this will change to also include ZFS, but have no idea when that might be. Bob Netherton has his ZFS presentation on his blog: http://blogs.sun.com/bobn In this ZFS presentation there's a picture of a NFS module sitting above the DMU. What that means is that ZFS will support NFS directly as part of the filesystem API. The example he gave is the potential of running a db like Oracle on such a NFS shared filesystem. I was going to ask if this meant such a share might eventually support local filesystem semantics like memory mapped files, but alas I had a meeting to run to. That might be a stretch anyway. Here are a few other links that I have handy... http://uadmin.blogspot.com/2005/11/zones-on-ufs-vs-zfs.html http://www.opensolaris.org/os/community/zfs/demos/selfheal/ ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
