Licensing: Setting Up the License Server on a Microsoft Cluster

This white paper provides details about setting up the Citrix License Server on a Microsoft Cluster. Cluster servers are groups of computers that are combined to increase availability, reliability, and scalability. A typical cluster configuration has, at a minimum, one active and one passive (backup) server. When the active server in a cluster fails, the ownership of the resources in the cluster is transferred to the backup (passive) server. Typically, users cannot detect when one server in a cluster fails over to another. Citrix Licensing supports clustering the license server with two servers in a cluster and a shared drive. That is, one can cluster the license server in a two-node Microsoft Cluster in an Active/Passive Microsoft clustering configuration.
