What I think original article author, Robin Harris, probably knew, but didn't point out explicitly, is that all the official "RAID" algorithms are ** block oriented **, RAID-1 just as much as RAID-5, and *that's* why they're "dead". The only question how long it'll take for better solutions to become widespread enough for us to ditch block-oriented RAID entirely. Everything else Harris mentions is just supporting detail. ZFS and Btrfs seem to have the right approach; end-to-end data assurance provided by the file system. I look forward to the time when I can easily use it for real on all my computers. -- Andrew Piskorski <a...@piskorski.com> http://www.piskorski.com/ _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
