As I understand active-backup mean that some OS daemon will enable a backup interface in case where primary interface will be down - it can be too slow for RAC -
Active - active (Linux eth bond) will give you a stability in case of one NIC failure - of course if you have more than one NIC and one switch. Be aware that RedHat 5 has some problem with proper order of ETH interfaces after reboot - see my post about it -
