Failover support was introduced into Management Center (MC) in version 1.5.2
Failover support in MC is similar to what customers are used to seeing in Director.
One device is designated as the primary (Active) the other is designated as the secondary (Passive) device
The secondary replicates data from the primary using secure SSH
Replication of data is near real time
Only the primary can be used to manage devices
Failover support can be configured on both two physical devices or on two virtual devices, however Symantec recommends using VMotion for failover support in a virtual environment. (One advantage to using VMotion in this scenario is that the customer only needs to purchase 1 MC license)
