For 100 TB, the methods change dramatically. You can't just reload 100 TB from CD or tape. When you get to this scale you need to be thinking about raidz2+ *and* mirroring. I will be exploring these issues of scale at the "Techniques for Managing Huge Amounts of Data" tutorial at the USENIX LISA '10 Conference. http://www.usenix.org/events/lisa10/training/ -- richard -- OpenStorage Summit, October 25-27, Palo Alto, CA http://nexenta-summit2010.eventbrite.com USENIX LISA '10 Conference November 8-16 ZFS and performance consulting http://www.RichardElling.com
