No. Each of the RAIDZs that you create can be combined into a single pool.

For 800TB of data that would be unacceptable. Today, you wouldn't be able to do it easily. In the future, you may be able to expand the RAIDz device. (or if you could remove a VDEV from a pool, you could rotate through and remove each of the RAIDz devices followed by an addition of a new (8-column) RAIDz). -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
