We have four brokers running across two machines on AIX with mutual failover support via HACMP. There are a number of reasons for doing this:
Each broker runs under a separate user account. This enables us to control how much CPU resource is assigned to each broker at the user ID level. Different brokers are used for different business areas. Execution groups within a broker handle work on behalf of different business systems. We can fail over at the broker level. Thus if one machine gets too busy and the other is idle, we can fail a broker from one machine to the other to re-distribute the load (to a certain extent). All brokers can fail onto a single machine in the event of a hardware problem to keep all flows running at reduced capacity. We can fail everything onto one machine so we can perform maintenance (e.g. apply CSDs, fixpaks, operating system patches etc) with minimal downtime (though at reduced capacity).

I prefer a single broker to simplify the MQSI administration.
