Of course it will. There's an error-checking protocol that runs over the SAN cable. Memory will detect errors as well. There's error checking, or checking and correction, every step of the way. Better integration of all of this error checking could be an improvement, though. -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
