Daniel, Imagine 2 servers afred with each other. On the client side you configure HA translator with its subvols as the afrs on the two servers. (Previously we used DNS round robin system) If 1st server goes down, the HA translator will continue working with the second afr and this failover happens seamlessly. on server1: AFR1 -> (server1posix + server2posix) [server2posix is connected using client translator) On server2: AFR2 -> (server1posix + server2posix) [server1posix is connected using client translator) AFR1 is on server1 and AFR2 is on server2. server1posix is on server1 and server2posix is on server2. Hence server1 and server2 are AFRed with each other. On client: HA -> (AFR1 + AFR2) [ AFR1 and AFR2 are connected using client translators) If server1 goes down, the HA will continue operating using its connection with AFR2. Was this clear?
