The Active/Active or Load-Sharing Configuration
In the load sharing configuration, each CPU manages six of the twelve I/O
slots, much like a dual 8-slot system with the added benefit of one CPU
being able to control all twelve I/O slots if the other CPU fails. It is
important in a load-sharing configuration to note that the total critical
activity does not exceed the capabilities of a single CPU, because either
one of the CPUs must be ready to take over the load carried by the other.

H.110 traffic and HA Linux do not support a load-sharing
configuration.
