What I've wondered about such a configuration is how you bring a disk back on line after it has failed. Do you rebuild the information on it by reading the other drives and using the ECC? If so how long does it take and what effect does it have on the performance of the system? Just curious. -- Toivo Pedaste ACSNET: toivo@uniwa.uwa.oz
