The vSphere Replication appliance provides all the components that vSphere Replication requires.

An embedded database that stores replication configuration and management information.

A vSphere Replication Management Server and a vSphere Replication Server that provide the core of the vSphere Replication infrastructure.

You can use vSphere Replication immediately after you deploy the appliance. The vSphere Replication appliance provides a virtual appliance management interface (VAMI) that you can use to reconfigure the appliance after deployment, if necessary. For example, you can use the VAMI to change the appliance security settings, change the network settings, or configure an external database. You can deploy additional vSphere Replication Servers using a separate .ovf package.
