Two dhcp servers with same dhcpd.conf (fixed-address hosts)

If all machines/clients use fixed addresses, you can simply run two servers - you don't need fail-over.
In this case, no matter which server replies, the clients will get the same addresses. There doesn't need to be any coordination between the two servers at all.

[However, obviously, as you change the fixed address assignments, you'll need to propagate those changes to both servers.]
