2.5 Cluster
Two types of clusters are possible in an SE server configuration.
2.5.1 Management Cluster
If two SE servers are combined into one Management Unit, it is called a "Management
Cluster" (or "SE Cluster").
A Management Cluster is configured by Customer Support based on the customer's wishes
and is used to operate und administrate the two SE servers together.
A Net Unit connection between the two SE servers (ISL-E) and one or two external
configuration disks for managing the global data are required to establish a Management
Cluster.
