cluster resource, allowing failover for higher availability in case o
f a system failure or planned
shutdown. Cluster resources are also created for other Insight Software components, including those
that are bundled with Insight Control and Insight Dynamics, allowing failover of these services.
Additionally, by distributing
the load for Microsoft SQL Server and Insight Software components on
separate systems, more efficient use can be made of cluster system resources.
This white paper describes the steps to install a highly available clustered version of Insight
Software on
HP ProLiant servers running Microsoft Windows Server 200
3
Enterprise
Edition
and
Microsoft SQL Server 2005
Enterprise
Edition

that are
registered with the DNS.
Within the cluster, the same network
