Supported VCS configurations and software

Both active/passive and N+1 configurations are supported, but active/active configurations are not.

In an active/passive configuration, a dedicated spare server is available for each Enterprise Vault server, ready and waiting for the primary server to go down. In an N+1 configuration, there is a computer for each Enterprise Vault server and then one or more spare servers waiting for any of the active servers to fail over.

The following software must be installed:

Veritas Storage Foundation HA for Windows, version 4.3 MP1 or later
Enterprise Vault
Windows Server 2003/2008

Neither Compliance Accelerator nor Discovery Accelerator must be installed on any server in the planned cluster. These products are not supported within a cluster. However, an unclustered Compliance Accelerator or Discovery Accelerator can reference a clustered Enterprise Vault virtual server.
