A cluster is configured by Customer Support as per the customer's request.
The Cluster main menu is displayed in the tree structure if you manage at least one cluster in your SE server configuration via the SE Manager:
Two or more SE servers are always managed in a Management cluster. Depending on the configuration, there can be one or more additional SU clusters.
In an SE server configuration with an SE server that has more than one SU x86s, an SU cluster can be configured. In that case, only the SU cluster but no Management cluster exists.
The Cluster -> Overview tab displays all clusters in the server configuration and their status.
In the Dashboard main menu, the Cluster -> Overview tile displays the status of the clusters in accumulated form, and the link branches to the Cluster -> Overview tab.
In the case of a Management cluster, the displays in SEM become correspondingly more complex.
Examples:
- The dashboard contains another tile called Cluster (also in case of an SU cluster only).
- Where necessary, tables contain a further column called Server, e.g. the central overviews for systems and units.
- Where necessary, menus are split into server-specific menus, e.g. for systems and units.
A detailed description of the cluster functionality is provided in the "Cluster Solutions for SE Servers" whitepaper [8].
