The Cluster Software

The cluster software enables servers across a network to work together in a computer cluster to provide application high availability.

Important! The steps described in this chapter apply to Microsoft cluster software and Active Directory only.

In a high availability deployment, the cluster software performs the following tasks:

Monitors the status of the primary and secondary Enterprise Management Servers
Verifies that only one instance, either the primary or secondary servers, is active at a time
Manages the CA Access Control services on the Enterprise Management Servers
Manages the shared host name that points the endpoints to the active server
