As mentioned in Section 5.1, Functional Requirements, individual servers must be designed to be redundant and have the ability to fail over if a host fails or hardware servicing is required. In addition, in the event of a site disaster at the on-premises data center, the VMware Cloud Provider Program data center must be able to service the entire user population.

The IT organization has determined that database failover between mailbox servers within the same data center must be automatic with no loss of data. However, administrative actions must be required in the case of a site failover.
