I'm also not so sure ZFS made that much sense for Apple. They sell some servers, but their target market is desktops and laptops. ZFS is great on a server, where you have multiple disks for redundancy and lots of RAM to satisfy ZFS's vast hunger for memory. On a single-disk laptop? Not so much. Remember, Apple still sells base systems with 2 GB of RAM. Even 4 GB is sometimes not sufficient to make ZFS happy, in my experience. (On one of my 4 GB fileservers ZFS would sometimes consume so much RAM that the ethernet driver couldn't allocate buffers.) I don't think ZFS was going to be a good end user experience on a typical Apple machine. -- David Brodbeck System Administrator, Linguistics University of Washington _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
