Cluster Planning 33
When a failed node reintegrates into the cluster, it takes back the resource
group for which it has the highest priority. Therefore, even in this
configuration, there is a break in service during reintegration. Of course, if
you look at it from the point of view of performance, this is the best thing to
do, since you have one node doing the work of two when any one of the
nodes is down.
Third-Party Takeover Configuration
Figure 4 illustrates a three node cluster in a third-party takeover
configuration.
Figure 4. Third-Party Takeover Configuration
This configuration can avoid the performance degradation that results from a
failover in the mutual takeover configuration.
