Primary Site - Virtualized - Failover Scenario
Among the advantages of virtualization is the redundancy that can be built in to the system. The
following diagram reflects a possible failover scenario that remains at full operational capacity while

windows.
The following chart shows the processor assignment-workload association. This distribution
demonstrates maintaining fully operational functionality while one host is offline.
