Figure: Enterprise Vault in an active/passive failover pair configuration illustrates a typical configuration.
In this example:
NODEA and NODEB are the two Enterprise Vault nodes in the Microsoft server cluster. NODEA is the primary node. NODEB is the failover node.
The SQL server and Microsoft Exchange may also be configured in the cluster: this does not affect Enterprise Vault.
The volumes for the Enterprise Vault services data are configured on shared storage.
The Enterprise Vault virtual server is configured on the primary node, NODEA. If NODEA fails, the virtual server's resources fail over to NODEB, and the virtual server comes online on NODEB.
