CLUSTERS

Example of clustering partitioned servers
You can include partitioned servers in a cluster. You can cluster partitioned servers with individual servers and with partitioned servers that are on different computers. Do not include partitioned servers that are on the same computer in the same cluster. Doing so can cause significant failover and workload problems in the cluster if that computer fails.

If you use port mapping for your partitioned servers, it is not a good idea to include those partitioned servers in a cluster. Because a failure of the port mapping server makes communication with the other partitioned servers impossible, this can cause failover and workload problems in the cluster.

The following figure shows two computers with three partitioned servers on each. These partitioned servers are configured in three clusters with two partitioned servers in each cluster.

Six partitioned servers configured into three clusters

When you include a partitioned server in a cluster, you do not have to include all the partitioned servers on a machine in the cluster. The following figure shows two computers that each have three partitioned servers. Four of the partitioned servers are configured in two clusters, and two of the partitioned servers are not in a cluster.

Only four of six partitioned servers are in clusters
